Rare-Rare(Rarity)

Twilight woke up from her nap and yawned loudly. That had been a good nap. Her eyes still closed, she felt Smarty Pants' soft touch on the side of her face. She hugged her tight and rolled onto her back, opening her eyes. The only thing she saw was a white face with dark-blue eyes, staring right at her. She yelped and sat up, seeing one of her best friends, Rarity, sitting in front of the rug, herself in a baby-blue onesie, similar to Twilight's, but in blue, and covered in gems.

"Rarity!", Twilight said, "Wh-why are you here?!"

"Rare-Rare!", Rarity said, her voice still sounding upper-classed, but babyish.

"What?!", Twilight said.

"My name Rare-Rare!", Rarity said again. At that point, Celestia had walked into the chamber, smiling as she saw her student awake.

"Good", she said, "You're awake".

"Princess C... Mommy!", Twilight yelled in fear, remembering what she had to call her, "Why is Rarity here?!"

"I invited her", Celestia said, "I figured you were getting lonely, so I invited one of your best friends".

"I was fine!", Twilight said, "And now she knows my secret! She knows about my foal fetish!"

"Well, maybe not", Celestia said.

"What d-", Twilight said, getting annoyed at Celestia, "She's looking right at me while I'm dressed as a foal!"

"Well, why don't you look at her?", Celestia said. Twilight rolled her eyes and looked at Rarity, who was suckling her hoof in boredom. Twilight then raised her eyebrow.

"Wh-why is she...?", Twilight asked, "What's going on?" Celestia smiled.

"I figured you would want a playmate to make your foal fetish better", Celestia said, "So, I decided to get your friends to play with you. I started with Rarity and made a deal with her to regress her and allow her to play with you". Twilight looked back at Celestia.

"So... she thinks she's a baby?", she asked.

"Yes", Celestia said, "I regressed her mind to the mind of a foal. She completely thinks she's a baby, and won't remember any of this, I promise". Twilight smiled a little.

"Oh, OK", she said.

"Now, why don't you go say hi to your friend?", Celestia said. Twilight looked at the mentally-regressed mare, feeling a little awkward Rarity pulled her saliva-soaked hoof out of her mouth and put it on the floor.

"Uh... hi Rarity", Twilight said. Rarity's bottom lip started to quiver, and Twilight could hear a small whimper come from her. "What's wrong with her?"

"You have to call her 'Rare-Rare'", Celestia said, "It hurts her feelings if you don't".

"Oh...", Twilight said, "Uh... hi... Rare-Rare". Rarity smiled and hugged Twilight very tight.

"Me love Twily!", she squealed in excitement, kissing her cheek. Twilight almost had to push Rarity off of her. The regressed mare giggled at Twilight and went back to suckling her hoof.

"Alright", Celestia said, "Would my little fillies like to play with their toys?"

"Me wanna play!", Rarity yelled, her hoof still in her mouth. Twilight just shrugged as Celestia put the toys in front of the mares.

"Play nice, you two", she said, "I have some paperwork to complete". Twilight nodded and played with the toys, as did Rarity. After a while, Rarity spotted Smarty Pants laying next to Twilight. She smiled and picked her up, cuddling her tight.

"Me like Smarty Pants", she said, petting Smarty Pants' mane. Twilight saw Smarty Pants being strangled in Rarity's hooves and gasped. Ever since Smarty Pants was stolen from her, Twilight didn't let anyone else touch her.

"Gimme her!", Twilight yelled, trying to pull Smarty Pants out of Rarity's hooves. Rarity may have been a lady, but she was strong, and it was a game of tug-of-war between the two.

"Twily!", Rarity whined, "Me wanna play with Smarty Pants!"

"No!", Twilight yelled, "She's mine!" Twilight finally pulled the doll out of Rarity's hooves and held her tight away from Rarity. Tears came to Rarity's eyes and she started crying loudly, alerting Celestia.

"What's going on?", she asked, walking over to the mares.

"Twily won't let me play with Smarty Pants!", Rarity whined, reaching for Smarty Pants.

"Rare-Rare", Celestia said, "Smarty Pants belongs to Twilight. Only she can decide who gets to play with her". Rarity began to cry again. Celestia only smiled and pulled out her secret plush she hid behind her pillow. "But, you can play with my friend, Sunny Dreams". Rarity looked at Sunny Dreams. The shininess of the plush was beautiful to Rarity's eyes.

"Thank you, Mommy", she said, taking the plush into her hooves. Celestia smiled and went back to her paperwork. Even though she did like playing with Sunny Dreams, she still wanted to play with Smarty Pants.

"Twily?", Rarity asked.

"What, Rarit- Rare-Rare?", Twilight said.

"Me play with Smarty Pants? Please?", Rarity asked, giving puppy-dog eyes. Twilight wanted to say no, but she didn't want to make her best friend cry again. Plus, Rarity was sitting next to her, so it wasn't like she was trying to steal her.

"OK", she said, holding Smarty Pants out to Rarity, "But please be careful with her". Rarity smiled.

"I be careful", Rarity said, "Smarty Pants Twily's friend. Me no hurt Twily's friend". Rarity took the doll and started playing with it as Twilight played with Sunny Dreams. But then, Twilight got an idea and smiled.

"Hey, Smarty Pants", Twilight said, moving the doll up and down to make it look like it was talking. "My name's Sunny Dreams". Rarity giggled and decided to do it too.

"My name Smarty Pants!", she said, "I like Twily and study and candy!"

"Me too", Sunny Dreams said, "Candy is the best food ever! What's your favorite?"

"Me like lollipop!", Smarty Pants said.

"Me like chocolate", Sunny Dreams said, "Even the ones with peanuts". Both mares giggled. After a while of playing, both Rarity's and Twilight's stomachs rumbled.

"Hungry!", Rarity yelled, rubbing her stomach.

"I could eat", Twilight calmly said. Celestia smiled, having just finished the last of her paperwork.

"Well, lunch is to be served in ten minutes", Celestia said, "Follow me, little babies". Twilight smiled and walked over to Celestia, as Rarity just stared. "Are you coming, Rare-Rare?"

"Pee-pee!", Rarity said, a small hissing noise easily heard. Celestia giggled.

"Seems she's wetting her diaper", she said, "Twily, I'm going to change her wet diaper. You and Smarty Pants go wash up and sit down". Twilight nodded and walked into the bathroom with Smarty Pants.

After Twilight and Smarty Pants finished washing up and Rarity got changed into a dry diaper, the three mares all went down to the dining room. Twilight sat down, Rarity sat down next to her, and Smarty Pants sat on the table. Celestia sat down across from the two mares and placed her napkin in her lap. Once everyone was settled, the chefs brought out the food, filled their drinks, and left. Everyone had gotten a 6" daffodil and daisy sandwich, along with a side of hay-fries, and Twilight was glad she could feed herself for this one.

"Alright", Celestia said, "Everyone be at their best behavior at the table, or there will be consequences, understand?"

"Yes, Ma'am", Twilight said. Rarity didn't care as she began eating her sandwich very fast. Both Celestia and Twilight giggled as they ate their own sandwiches.

"Uh, Twily?", Smarty Pants said. Twilight smiled and grabbed the doll.

"Yes, Smarty Pants?", Twilight whispered to the doll.

"I don't like this", Smarty Pants said, "I liked when it was just you and me playing together, and when only you were the baby".

"Smarty Pants...", Twilight said, "I did too, but if we want Princess Celestia to stay as the mommy, we have to play with our friends too".

"I know, but it's not the same", Smarty Pants said, "And Rarity was hugging me too hard. She could have split me in half if she wanted to".

"But I made sure she didn't", Twilight said, "Now, if you let me do this, I'll make it up to you, I promise". Smarty Pants smiled and grabbed a hay fry from Twilight's plate, chewing it with a loud noise. "Hey, that was mine!"

"Do you want it back?", Smarty Pants said, opening her mouth and sticking out her tongue, showing Twilight the chewed hay fry. Twilight giggled.

"No thank you", Twilight said, "You can have it". Smarty Pants smiled and swallowed the hay fry, wiping the grease from her mouth. Soon, everyone finished their lunch and Celestia had the maids collect the plates and silverware.

"It seems everypony was good at the table", she said, "In that case, who wants dessert?"

"Me me me!", Rarity chanted, raising her hoof high. Celestia giggled again and had the chefs bring out some chocolate cake for herself and some banana pudding for the "foals". Rarity ate her's like a dog, her face buried in it. Twilight giggled. Seeing Rarity act like that was so funny to her, considering she would never see her do that with her adult mind.

After finishing their dessert, the three mares went back upstairs, Smarty Pants riding on Twilight's back. Once they got into Celestia's bedchamber, Twilight and Rarity went back to playing with their toys. With her paperwork finished and no court to attend, Celestia played too. Twilight smiled, liking the presence of her mentally-regressed friend. Acting like a foal was fun, but sharing her fetish with her friend was better. She enjoyed playing, until a nasty smell assaulted her muzzle.

"Poopy!", Rarity said, "I make poopy!" Twilight looked at the back of Rarity's onesie, seeing it puffy and bulged. Twilight giggled again, knowing this definitely wasn't something she would see Rarity do.

"Oh my", Celestia said, "I think somepony needs a change". Celestia picked up the regressed mare and laid her on the bed to change her diaper.

"Mommy?", Twilight said, having just finished messing her own diaper, "I make poopy too". Celestia smiled and laid Twilight on the bed also. After changing the two, she looked at them again.

"OK, my little fillies", she said, "Bath time".

"Bath time?", Twilight asked.

"Yes", Celestia said, "Let's get you two cleaned up". Celestia carried Twilight and Rarity into the bathroom and ran the water in the tub, pouring in some bubble bath to make the water bubbly. While the tub ran, she undressed the mares and set them in the tub.

"Me like bath!", Rarity said, splashing the water right in Twilight's face out of happiness, "Oops, sorry Twily".

"It's OK, Rare-Rare", Twilight said, returning the favor of splashing the water in Rarity's face, making the regressed mare giggle.

"Fun!", she said.

"Alright, no splashing, please", Celestia said, "I don't want to have to clean up too much".

Both mares nodded as Celestia grabbed her golden pouf and soaped it up. Starting with Twilight, she lightly scrubbed her mane, Twilight keeping her eyes closed to avoid getting soap in them. Then, Celestia moved on to her neck and belly. Twilight turned her back toward Celestia and allowed her to clean her wings and her tail. After cleaning her private area, Celestia then moved on to Rarity, cleaning her the same way. Rarity began to giggle and squirm as it tickled her a bit.

"Hold still, Rare-Rare", Celestia said, "I'm almost finished". After cleaning Rarity, she drained the tub and dried the mares off, putting them back in their diapers and onesies. Then, she carried them back into her bedchamber and sat them on the rug.

"Mommy", Rarity said, "Me sleepy".

"Me too", Twilight said. Celestia smiled.

"Well let's get you two in bed, shall we?", she said. She went into her closet and pulled out a small crib she built for Twilight's fetish and laid the two mare down, tucking them in with the blanket. After that, she reached behind her pillow and grabbed two foal bottles, full of warm milk for the mares to help them sleep.

"Good night, my little angels", she said.

"Ny-ny, Mommy", Rarity said, suckling her bottle.

"Night, Mommy", Twilight said, hugging Smarty Pants tight. Celestia turned her light off and laid down on her rug, catching her own Z's.

~~~~~~~~~~

Rarity yawned lightly and sat up, taking the sleepy-time blinder off of her eyes and rubbing them. She looked around and saw that she was in her own room, in her own bed, wrapped in her own robe. She then saw something on her dresser next to her, along with a note from Celestia. Rarity grabbed the note and read it softly to herself.

"Dear, Rarity", she said, "Thank you for allowing me to regress you and play with Twilight Sparkle. Honoring my part of the deal, I have given you a year's supply of Canterlot's most expensive fabrics which I have placed in your closet". Rarity stood up and walked over to her closet, seeing several colored, and shiny fabrics that all cost a fortune. She squealed with joy, thinking about all the money she could make and how pleased Sapphire Shores would be after buying one her her new dresses.

"Remember", Rarity continued to read, "You know about Twilight's foal fetish now, but you must keep it to yourself. Do not tell anypony else, period. If you should ignore my orders and speak to another soul, the fabrics I have given you will vanish and you will have no reward. Your Princess, Celestia".

"You have my promise, Princess", Rarity said to herself, "I will keep it to myself". She grabbed a roll of fabrics and placed it on her ironing board, as she heard her front door open.

"Ms. Rarity?", Sapphire Shores' voice called out, "I'm here, just like you requested". Rarity squealed again and quickly ran downstairs.

Author's Note

Rarity's chapter has been completed. (I know it's a bit shorter than the previous one, but that's because it didn't contain Twilight's foal fetish explanation. Trust me, they will get better).

Anyway, there are four characters left before background ponies can be selected. And after the last member of the Mane Six has been selected, Spike will go after it, since he technically is a main character in the show.

Remaining: Applejack, Rainbow Dash, Fluttershy, and Pinkie Pie. Start voting now!

Dashie(Rainbow Dash)

Twilight woke up when she felt a tickle on her nose. She groaned and used her hoof to scratch her muzzle, only to feel something powdery on her face. Opening her eyes, she saw foal powder all over her face and hoof. A bit of confusion struck her as she sat up, but she then realized she had been pranked. Twilight became angry and looked at Smarty Pants, who was sleeping peacefully.

"Smarty Pants!", she said, "Why did you sleepy-prank me?! I thought we agreed to stop that!"

"I didn't prank you, Twily", Smarty Pants said, her face still buried in her pillow, "I would never do that". That's when she heard a raspy giggle.

"Me got you, Twily!", the voice said. Twilight sighed with frustration , knowing who had done it.

"Of course", she said, "It was you, Rainbow Dash". The voice began to laugh again. Sure enough, it was Rainbow Dash, who was dressed just like Twilight, a bottle of foal powder in her hoof. Twilight shook the foal powder off of her face and blew it off of her hoof.

"Why did you do that, Rainbow Dash?", Twilight asked, "That was mean!"

"My name Dashie!", Rainbow Dash said, "Rainbow Dash my sissy". Twilight sighed.

"Right...", she mumbled, "Just like Rarity, she thinks her nickname is her real name". At that moment, Celestia walked into the room, having finished raising the Sun.

"Good morning, my little filly", she said, kissing Twilight's cheek, "Feeling alright this morning?"

"Yes, Mommy", Twilight said, ignoring the uncomfortable cold wetness in her diaper, "But Rainbow D-, I mean 'Dashie', put powder on my face while I was sleeping".

"Nuh-uh!", Rainbow Dash said, giggling again, "YOU did. You scratch your nose and put powder on you". Celestia sighed.

"Dashie, I said no pranking", she said, "Twily doesn't like it when you do that". Rainbow Dash pouted.

"No!", she yelled at Celestia, "Me wanna prank!" Celestia stood over the regressed mare.

"If you do that one more time", she said, "Somepony's gonna get a timeout". Rainbow Dash gulped in fear. "Do you want a timeout?"

"No, Mommy!", Rainbow Dash said, "Me be good!" Celestia smiled and pet Rainbow Dash's head.

"Good Dashie", she said as Rainbow Dash suckled her hoof in boredom.

"So", Twilight said, "You chose her next?"

"Yes", Celestia said, "She was the next one I had in mind".

"Are you sure she's regressed?", Twilight curiously asked, "She seems like her normal self".

"Well, she was a bit of a debater", Celestia said, "So not only did I have to regress her mind, I had to remove any memories of her adulthood. But don't worry, I'll return them to her after tonight".

"So she doesn't know that she's an adult?", Twilight asked.

"No", Celestia said, "And she will not remember any of this". Testing Rainbow Dash, Twilight looked at her.

"Hey... Dashie", she said, "How old are you?" Rainbow Dash smiled, pulling her hoof out of her mouth.

"Me three years old!", she said. Twilight laughed under her breath. "How old Twily is?"

"I'm twenty-f...", Twilight said, before cutting herself off, "I mean, four". Rainbow Dash gave a toothy smile.

"Yea!", she said, hugging Twilight, "Twily my big sissy! Me love Twily!" Twilight literally had to push Rainbow Dash to separate them.

"I... uh... love you too... Dashie...", she forced herself to say, feeling very uncomfortable. Celestia smiled.

"Twily", she said, "Why don't you introduce Dashie to Smarty Pants? I'm sure they'd get along". Twilight smiled, crawled over to Smarty Pants, and picked her up, carrying her over to Rainbow Dash.

"Dashie, this is Smarty Pants", she said, "She's my best friend, and likes to study, just like I do". Rainbow Dash smiled.

"Me hold her...?", she asked, reaching out for Smarty Pants. Twilight, with a little bit of unease, gave Smarty Pants to Rainbow Dash. Rainbow Dash happily played with her for five seconds, then caught a glimpse of two loose threads hanging from Smarty Pants' button-eyes. Smiling evilly, Rainbow Dash purposely pulled on them with her teeth. The threads were pulled completely out of Smarty Pants, making both of her button-eyes fall on the floor. Twilight yelped as she saw the buttons fall off of her sister.

"Smarty Pants!", she said, quickly snatching her from Rainbow Dash's hooves, "Dashie! Why did you do that?!" Rainbow Dash giggled.

"I don't know...", she sarcastically said, chuckling again.

"Mommy!", Twilight whined to Celestia, who had been reading a book.

"Yes, Twilight?", she asked.

"Dashie pulled Smarty Pants' eyes out on purpose!", Twilight said. Celestia walked over to the mares and picked up Smarty Pants, seeing her button-eyes were missing.

"Dashie... did you do this?", she asked. Rainbow Dash giggled again.

"Nope!", she confidently said. Celestia sighed.

"I really don't like it when ponies lie to me, Dashie", Celestia said.

"Me no lie, Mommy...", Rainbow Dash argued. Celestia shook her head.

"You did it again", she said, "Just for being untruthful, you get a timeout. I want you to stand in the corner until I stitch Smarty Pants' eyes back on". Rainbow Dash frowned.

"No!", she said. Celestia raised her eyebrow.

"Are you being defiant?", Celestia asked, "See, when I was a little filly, and I was defiant to my mommy, I didn't get timeouts... I got this..." She opened her closet and pulled out a long meterstick, dangling it in front of Rainbow Dash. Rainbow Dash saw the meterstick and gasped. Her fear was so great that she began to soak her blue diaper.

"No mommy!", she begged, "No spankies! Please!" Celestia smiled and put the meterstick back in the closet.

"Thank you", she said, "But if you make a no-no again, I won't hesitate to use that". Rainbow Dash nodded and stood un the corner, while Celestia smiled at Twilight.

"Don't worry, sweetie", she said, kissing her cheek and picking up the buttons from the floor, "Just give me a few minutes, and I'll have Smarty Pants seeing again". Twilight smiled as Celestia sat on her bed and pulled her sewing kit. After just five minutes, Celestia had sewed the buttons back onto Smarty Pants as tight as she could so they couldn't be pulled off again. Celestia gave the stuffed pony a kiss on her cheek and gave her back to Twilight.

"There you go, Twily", she said, "All fixed". Twilight gasped and smiled, grabbed Smarty Pants.

"Smarty Pants! You're OK!", she said, hugging her tight, "Mommy! Thank you!"

"You're very welcome, Twily", Celestia said. She then looked at Rainbow Dash, who was still standing with her nose in the corner. "Dashie, I believe you owe a certain pony an apology". Rainbow Dash nodded and crawled over to Twilight.

"Me sorry Twily... and Smarty Pants...", she said.

"That's OK, Dashie...", Twilight said, "Just... please don't hurt her again..." Rainbow Dash looked at Celestia.

"Wet...", she said, pointing at her crotch. Celestia smiled.

"Alright Dashie", she said, "Let's get you changed". Celestia used her magic to pick Rainbow Dash up and lay her on the changing table. "Twilight, while I change Dashie, go wash up. Dinner is in five minutes".

Twilight nodded and after washing up, she went downstairs to the dining room, sitting in one of the chairs and sitting Smarty Pants comfortably in her lap, lightly petting her head as she waited for Celestia and Rainbow Dash.

"Twily...", Smarty Pants said, rubbing her sore button-eyes.

"Yes, Smarty Pants?", Twilight asked.

"Why did you let Rainbow Dash do that to me...?", Smarty Pants asked.

"Oh...", Twilight said, "Don't say it like that... you know I didn't know she'd pull your eyes out".

"But it hurt so bad, Twily!", Smarty Pants said, "I couldn't see! You said you'd never let anypony hurt me!" Twilight felt a bit guilty.

"Smarty Pants...", she said, "I'm sorry... you know I love you more than anything else..." Smarty Pants smiled a little.

"OK, Twily...", she said, "But please... don't let Rainbow Dash play with me again..." Twilight giggled.

"I won't", she said, kissing her cheek. At the same time, Celestia and Rainbow Dash came into the dining room and sat at the table as they all received their dinner: spaghetti with Brussel sprouts.

"Alright, everyone be on their best behavior, OK?", Celestia said, placing her napkin in her lap.

"Yes Mommy", Twilight and Rainbow Dash said. Everyone began eating. After twenty minutes, Celestia had finished her meal and Twilight had Lady-and-the-Tramp-ed the last noodle with Smarty Pants. Rainbow Dash however, had finished her spaghetti, but was picking at her sprouts.

"Eww!", she said, "Yucky!" Celestia looked at Rainbow Dash.

"Dashie, eat your vegetables", she said, "They're good for you".

"No! Yucky!", Rainbow Dash said, pushing her plate away from her. Celestia sighed.

"Dashie, if you don't finish those sprouts, you're not getting any dessert", she said. Rainbow Dash blew a raspberry at Celestia, pushing her plate further away from her. Celestia shook her head. "Alright, no cake for Dashie. Twilight, it looks like you get two slices". Twilight giggled.

"No I don't", she said, "I get one, and Smarty Pants gets one". Celestia chuckled.

"Right", she said, "My apologies, Smarty Pants".

"It's OK, Mommy", Smarty Pants said, blowing Celestia a kiss.

Two hours later, the mares were all in Celestia's bedchamber again. Celestia was attending Day Court, while Twilight and Rainbow Dash were playing inside a large playpen that Celestia had hidden in her closet. Rainbow Dash however, couldn't enjoy herself, thanks to her growling stomach. Since she didn't have any dessert, or finish her dinner, her stomach was paying for it. As her stomach growled for the thirtieth time, she moaned.

"Twily...!", she whined, "Me hungry!" Twilight looked up from Smarty Pants.

"Dashie... I don't know what you want me to do about it...", she said, "You should've finished your dinner..."

"Me not wanna eat yucky food!", Rainbow Dash complained, "Me want cookies!" Twilight sighed.

"I don't have any cookies, Dashie...", she said, "I can't help you". Rainbow Dash smiled.

"Uh-huh!", she said, "There's cookies in kitchen!"

"But we're in here", Twilight said, "What do you want me to do?" Rainbow Dash chuckled.

"Well...", she said, raising her eyebrows. Twilight caught what Rainbow Dash was getting at.

"No no no", she said, shaking her head, "I'm not sneaking cookies from the kitchen".

"Twily... come on!", Rainbow Dash tried to persuade, "Me hungry!"

"But I'm not getting in trouble for you", Twilight said. Rainbow Dash saw Smarty Pants in Twilight's hooves. Smiling evilly again, she snatched the doll from Twilight's hooves, Twilight yelping.

"Hey!", she said, "Give her back!"

"Me give you Smarty Pants if you help me get cookies...", Rainbow Dash said.

"No!", Twilight refused, "I'm not getting in trouble for you!"

"OK...", Rainbow Dash said. She then grabbed Smarty Pants by the tail with her teeth and gave it a tug, loosening the threads. Twilight gasped, knowing it was only a matter of time before she saw Smarty Pants' cotton-guts again.

"Dashie, no!", Twilight begged, "Please don't hurt her!" Rainbow Dash let go for a minute.

"Cookies...?", she asked. Twilight grunted in desperation, knowing the only way to keep her friend from suffering another injury was to go with it.

"F-fine...", she said, "Just please don't hurt Smarty Pants!"

Rainbow Dash smiled and gave Smarty Pants back to Twilight. Twilight used her magic to levitate herself and Rainbow Dash out of the playpen and down to the kitchen. Once they got there, sure enough, there was a cookie jar sitting on the counter. Rainbow Dash climbed onto the counter, sitting on it and opening the cookie jar, her mouth watering at the assorted goodies.

"Just pick a few so we can get back upstairs...", Twilight said, "I don't wanna be caught down here by Mommy..." Rainbow Dash completely ignored Twilight and began to scarf down several hooffuls of cookies. As seconds went by, Twilight began to get more and more impatient.

"Dashie... come on...", she said. Rainbow Dash continued to stuff her face. "Dashie... I think you've had enough..." Rainbow Dash continued to eat.

"Dashie!", Twilight said sternly with her teeth clenched, "That's enough! Please, let's get back upstairs!" Rainbow Dash grabbed a few more cookies, but rather than eating them, she stuffed them in her diaper and jumped down from the counter.

"OK, Twily", she said, "I'm done". Twilight raised her eyebrow in surprise.

"Did you stuff cookies in your diaper...?", she asked.

"Mm-hmm!", Rainbow Dash said, "For later!" Twilight sighed.

"Alright...", she said, "Just, don't soil yourself before you get those out". Twilight and Rainbow Dash snuck back upstairs to Celestia's bedchamber. Unfortunately, when they opened the door, Celestia was standing in the door frame, not looking too happy.

"Well well well...", she said, "Did you two enjoy your little field trip?"

"Mommy...", Twilight said, "We just went and got a glass of water. Dashie said her throat was hurting". Rainbow Dash nodded in agreement.

"Really...?", Celestia said, "Then why do I smell cookies on her breath?" She used her magic to pull the back of Rainbow Dash's diaper down. "And why are there cookies in your diaper, Dashie?"

"Uh... uh...", Rainbow Dash mumbled.

"Dashie, I believe I said you do not get any dessert", Celestia said, "Only fillies that eat all of their dinner can have dessert. You refused to finish your sprouts, and instead went behind my back and stole cookies from the jar. You were defiant, Dashie, and you know what I said would happen if you were defiant..." Rainbow Dash gulped.

"No Mommy!", she begged, "No spankies!"

"I'm sorry Dashie...", Celestia said, "But you've given me no choice..."

Celestia used her magic to carry Rainbow Dash over to her bed. Celestia sat down, and draped Rainbow Dash over her knee. She pulled the back of her diaper down, exposing her behind, and pulling the meterstick out of the closet once more. Not wasting any time, Celestia began to spank Rainbow Dash with the meterstick. Rainbow Dash cried and squirmed as the meterstick smacked her bottom several times. After spanking Rainbow Dash fifteen times, Celestia finally stopped and looked at Rainbow Dash.

"Have you learned your lesson?", she asked.

"*sniffle* Yes!", Rainbow Dash whined, "No more! Please!" Celestia smiled.

"OK", she said, "Just don't make me have to do it again". Celestia then used her magic to remove the cookies from Rainbow Dash's diaper and dump them in the trash. "I'll get you a fresh cookie in a minute, OK?" Rainbow Dash smiled.

"OK, Mommy", she said. Celestia kissed Rainbow Dash's cheek and let her go.

"Now, as for you Twily...", Celestia said. Twilight's eyes widened.

"What did I do?!", she complained.

"You helped Rainbow Dash defy me", Celestia said, "And not only that, but you lied to me when I caught you. You must receive a punishment for that".

"But Mommy!", Twilight whined, "Can't I just get a timeout...?"

"I can't be that lenient, Twily...", Celestia said, "It wouldn't be fair to Rainbow Dash".

"But... but...", Twilight continued to debate.

"Twily, it'll be better if we just get it over with now", Celestia said.

Twilight sighed and finally listened. After setting Smarty Pants down with her ears and button-eyes covered, she walked over to Celestia and draped herself over her knee. Celestia used her magic to pull the back of Twilight's diaper down, exposing her purple bottom. Just seconds later, Celestia began to spank Twilight with the meterstick. Twilight cried in pain, squirming hard as the meterstick repeatedly smacked her flank. She never thought she'd be receiving that form of punishment from Celestia. After fifteen spanks, Celestia stopped, looking at Twilight.

"Have you learned your lesson?", she asked.

"Y-yes, Mommy!", Twilight said. Celestia smiled and kissed her cheek.

"OK then", she said, putting the meterstick back in her closet, "Dashie, let's go get your cookie so I can get you and Twily in bed". Rainbow Dash nodded and followed Celestia to the kitchen.

"Mommy?", Twilight asked, her bottom still a little sore.

"Yes, Twily?", Celestia said.

"I made a messy...", Twilight said, showing Celestia her full diaper to prove it. Celestia smiled.

"Well, Dashie did too", Celestia said, "Let's get you two changed so you can lay down for the night". Two changes later, Celestia carried the two foals to the large crib, tucked them in, and dimmed the lights.

"Goodnight my little angels", she said, giving them both a kiss on their muzzles.

"Night, Mommy", Rainbow Dash said, instantly rolling over and passing out. Twilight giggled, knowing that was just what Rainbow Dash did.

"Goodnight, Mommy", Twilight said. Celestia smiled at Twilight and laid down on her carpet. Twilight rolled over and tried to go to sleep, but she heard someone speak to her.

"Twily...?", Smarty Pants asked. Twilight smiled and looked at Smarty Pants.

"Yes, Smarty Pants?", she asked.

"Th-thank you for not letting Rainbow Dash hurt me anymore...", Smarty Pants said, "Even though you got spankies for it..."

"Like I said, Smarty Pants", Twilight said, "I would never let anypony hurt you, and I wasn't going to start then. Even though I had to be hurt a little bit, I saved your life, and I want to keep you safe". Smarty Pants blushed.

"Thank you Twily", she said, kissing Twilight's cheek, "At least 'Dashie' is leaving tomorrow". Twilight giggled.

"Yeah", she said, "And you won't have to see her again". Smarty Pants smiled and yawned.

"Goodnight, Twily...", she said, "I love you..."

"I love you too, Smarty Pants", Twilight said, slowly falling asleep.

~~~~~~~~~~

Rainbow Dash woke up in the bed of her cloudhouse and gave a very long and completely audible yawn, smacking her lips a few times afterwards. After rubbing her red eyes and getting them level with each other, she spotted two letters on her nightstand, one wrapped in a blue ribbon, the other in a yellow one. She first picked up the blue letter and opened it, reading it aloud to herself.

"Dear Rainbow Dash", she uncaringly mumbled, "Thank you so much for allowing me to mentally regress you and play along with Twilight". Rainbow Dash snorted hard through her nose in anger.

"Are you serious, Celestia?!", she yelled, "I said no fifty times and you still did it anyway?! Ooh! You're lucky you're a frickin' Royal, because if you weren't I swear!" Rainbow Dash took a deep breath, calming herself down. "Calm down, Dash. Just finish the letter before you become a total hothead. That's Applejack's job". Rainbow Dash continued the letter.

"And I apologize greatly for ignoring your orders", she read, "To prove that I really am sorry, I have given you a very great reward that I'm sure you will enjoy. But be warned, you now know about Twilight's foal fetish, and you must keep it to yourself. Should you ignore my orders and tell any other soul, you will no longer have this reward. Yours, Princess Celestia". Rainbow Dash raised her eyebrow and started looking all over the paper for her reward.

"But, where's the reward?", she asked. She then peeked at the yellow letter. After putting down the blue letter, she opened the yellow one and read it.

"Dash", she read, "Come to my office as soon as you get this letter. I gotta tell you something that I'm sure you'll wanna hear. Spitfire".

Rainbow Dash jumped out of her cloudbed, threw on her Wonderbolts uniform, and flew to Cloudsdale. Once she got there, she flew to the Wonderbolts Training Center and to Spitfire's office. The door was open, and inside was Spitfire, sipping coffee and smiling at Rainbow Dash.

"Hey, Cadet Dash", she said, "How's it going?"

"You requested for me, Captain Spitfire?", Rainbow Dash asked. Spitfire chuckled.

"I really hope you aren't used to calling me that", she said, "Because you don't have to anymore". Rainbow Dash raised het eyebrow in surprise.

"Whaddya mean?", she asked.

"Well", Spitfire said, smiling in delight, "Why don't you come open this envelope on 'my' desk and find out?"

Rainbow Dash shrugged and walked over to Spitfire's desk, seeing an envelope with her name on it. She picked it up and opened it, sliding out what was in it. It was a solid gold medal, with Rainbow Dash's cutie mark on it, and under it said "Superior Captain".

"This is a Captain's medal, with my name and cutie mark on it...", Rainbow Dash said. Her eyes then began to raise in surprise. "Wait... does that mean... what I think it means?" Spitfire smiled.

"Yep", she said, "As of today, Rainbow Dash, I officially name you, Captain of the Wonderbolts!" Rainbow Dash's eyes almost popped out of her head.

"Oh Celestia!", she yelled, "You're pulling my hoof. You can't be serious!"

"Nope", Spitfire said, "This office is all yours, Dash. You're the new Captain, and I'm the Co-Captain". Rainbow Dash's eyes went even bigger.

"Wait, you mean, you listen to me now?!", she said.

"Yep", Spitfire said. Rainbow Dash smirked.

"Prove it", she said, "Go get me an oat smoothie. A good one from Guava Splash". Spitfire nodded.

"You got it, Captain Dash", she said, walking out of the room. It was at that point when Rainbow Dash knew Spitfire wasn't kidding, and what her reward was.

"So that's what you were talking about, Princess...", she mumbled to herself, "Well, I ain't gonna tell nopony else! I'll staple my lips shut if I have to!" Rainbow Dash sat in her new office chair, propping her hind hooves on the table.

"Oh yeah, and thanks".

AJ(Applejack)

Twilight woke up the next morning and gave a pleasant yawn, smacking her lips a few times. A familiar foul smell punched her muzzle, but wasn't enough to make her cringe. Smelling the odor, Twilight rolled over onto her back and poked the back of her diaper, expecting to feel the squishy feeling she loved. But, when she only felt dry cotton brush against her behind, she became confused, then looked at Smarty Pants.

"Smarty Pants... did you pass gas...?" Twilight asked curiously. Smarty Pants rubbed her button-eyes.

"No, Twily..." she said, yawning, "It would be great if I could, but I can't..." Twilight raised her eyebrow and poked again to make sure she was clean, feeling the same dry cotton.

"*giggle* That's not'chou..." a Southern-sounding voice, "I'm the stinker over 'ere." Twilight looked to her left, her eyes raising in surprise. Her best friend Applejack was sitting next to her, wearing an orange onesie, the outline of her diaper easily seen. Sure enough, judging by the bulge showing underneath her tail, she had messed her diaper.

"Applejack?" Twilight asked. Applejack giggled.

"Well, Princess Celestia said mah name would be AJ..." she said, "But yeah... it's me."

"Are you... not regressed?" Twilight asked.

"Nope," Applejack said, "I'm still me." At that moment, Celestia flew in through the window, smiling at Twilight.

"I see you've been conversing with your friend," she said.

"You chose Applejack next?" Twilight asked.

"Yes," Celestia said, "And luckily, she wasn't hard to persuade either."

"Nope," Applejack said, "I was quick ta say yes when Princess Celestia offered me to do dis."

"So... you've got a foal fetish too?" Twilight asked.

"Well, not exactly," Applejack said, "I've got a diaper fetish, but not b'cuz I like actin' like a filly."

"Why?" Twilight curiously asked.

"Well, it's a bit of a long story," Applejack explained, "As ya know, I lost mah ma and pa to timber-wolves when I was a little filly." Twilight nodded, feeling a bit sorry for her. Every time she heard that, she'd feel bad, even though Applejack was fully over it. "I was four, Mac was ten, and Apple Bloom was only a few months old. So then, of course, Granny Smith took me and Mac in, and she let me stay in 'em for two more years, because I always felt snug in 'em. It was like I was still bein' cuddled by Ma and Pa whenever I wore 'em or Granny Smith and Mac changed 'em. It was like mah diapers were a way fer me to feel like mah folks are still able to hold me in their hooves."

"Wow," Twilight said, "It sounds like you really enjoyed wearing diapers. But, what made you give them up?" Applejack looked at the rug she was sitting on.

"I was forced to give 'em up when I was livin' with Aunt and Uncle Orange in Manehattan," she said. Twilight gasped.

"You mean...?" Twilight asked, "You weren't ready to give them up when you did...?"

"No," Applejack continued, "See, I got there, and I was happy to see 'em, but they weren't happy to see me, because I had pooed mahself right b'fore I had knocked on the door. So they yelled at me and made me clean mahself, and threatened ta punish me if they caught me wearing them again, b'cuz they said they weren't gonna deal with a stinky little filly, even though Granny Smith allowed it. B'sides, Granny Smith and Big Mac never complained about me bein' stinky when they changed me, b'cuz livin' on a farm all yer life practically makes yer muzzle invincible to the smell of poo, so I never thought anypony would think that I was a stinky filly. In fact, Granny Smith and Big Mac said mah dirty diapers weren't as stinky Apple Bloom's."

"Makes sense..." Twilight mumbled as Applejack finished up.

"So... within the three months I lived with Aunt and Uncle Orange, I finally learned how to use a commode..." Applejack finished, looking down at the floor in sadness, "...even though I was forced to sit on it fer six hours every day with nothin' to do, even if I didn't have ta go... they coulda at least given me a newspaper to read or somethin..." Twilight felt extremely sorry for her as Celestia pat her back lightly.

"And that's why I chose Little Applejack next," Celestia said, "After finding out about this tragic past she had, I felt that she deserves a night of wearing diapers along with a friend."

"But, I've got more than just a diaper fetish," Twilight said, "I've got a FOAL fetish, meaning I completely love acting like a filly. You said you only have a diaper fetish."

"Yeah," Applejack said, "But that don't mean I can't try it out. I'm an adventurous mare, and foals wear diapers, so I figured I'd give it a try." Twilight smiled.

"Alright then," Twilight said, "But, when I'm in Baby Twily mode, I don't hold back. If I need to fill my diaper, I'll do it, even if you're around me." Applejack chuckled.

"Twily, yer talkin' to a filly whose wearin' a poopy diaper," she said, "Ya think I'm gonna care if ya poo yer's around me?" Twilight smiled.

"I guess not," she said.

"Exactly," Applejack said, "I'm just here to be yer playmate fer the day b'fore Princess Cel-" Applejack cleared her throat. "'Scuze me... b'fore Mama has ta take me back home." Celestia smiled.

"Well, I hope you enjoy your experience, AJ," she said, "And I'm sure Twily would be happy to have you around. In fact, Twily has a sister who would love to meet you." Celestia winked at Twilight, who smiled and uncovered Smarty Pants, lightly lifting her off the rug and showing her to Applejack.

"Applejack, this-" Twilight started to say, before Applejack cut her off.

"Pardon me fer interruptin' Twily," Applejack said, "But, mah name's AJ." Twilight smiled and corrected herself.

"My apologies, AJ," she said, "Anyway, this is Smarty Pants, my little sister." Applejack smiled and took her.

"Well howdy there, Smarty Pants!" she said, "I haven't seen ya since Twily gave ya that weird spell and ya-"

"AJ!" she said, quickly cutting her off, "She doesn't like to talk about that... so please don't."

"Oh, alright," Applejack said, "Pardon me, Smarty Pants." Smarty Pants smiled.

"It's OK, AJ," she said, snuggling into Applejack's mane, "Mmm... you smell like apples..." Applejack smiled as well, liking the compliment.

"Why, thank ya, Smarty Pants," Applejack said, "And you smell like fresh cotton." Smarty Pants blushed as Applejack noticed she was missing something. "Hey wait, if yer Twily's little sis, why ain't'cha wearin' a diaper? Yer a foal too right?" Smarty Pants looked down.

"Yeah... but there aren't any diapers that can fit me..." Smarty Pants said, "And plus... I can't make them stinky..." Applejack smiled and comfortably cuddled Smarty Pants as Celestia gave them their space.

"Smarty Pants, just b'cuz ya can't make 'em stink don't mean ya can't wear 'em," she said, "And as fer the size, why don't'cha let 'cher sissy AJ fix that fer ya." Applejack looked around the bedchamber, seeing a table full of expensive cloths Celestia uses for cleaning. "Hey Mommy, may I borrow some of yer cloth?"

"Go ahead, AJ," Celestia said. Applejack smiled and grabbed a piece of purple cloth, using scissors to cut it into a smaller square. After that, she placed Smarty Pants on the changing table and laid her down, wrapping the cloth around her waist like a diaper, and stitching it together so it wouldn't fall off.

"There ya go, Smarty Pants," she said, "Now ya got a diaper that's just yer size." Smarty Pants looked at it, gasping hard.

"I love it!" she excitedly yelled, "It's so soft and cuddly! And purple's my favorite color!"

"And," Applejack said, lightly sliding it down a little, "Twily can always slide it off of ya, just in case ya want a pretend change."

"Thank you, AJ!" Smarty Pants said, kissing Applejack's cheek repeatedly.

"Yer welcome, Smarty Pants," she said, taking her back to Twilight.

"Well, you sure made her happy," Twilight said, "How'd you do that?"

"It's just a little trick I learned while in Manehattan," she said, "I wanted to buy some cloth diapers and hide them from Aunt and Uncle Orange, but they were too darn expensive, so I made mah own, b'fore I was caught."

"Wow... I should try that one day..." Twilight said. Applejack felt her stomach growl.

"I don't know abou'chu, Twily," she said, "But I could use some chow."

"So could I," Twilight said.

"Me too," Smarty Pants said, rubbing the front of her new cloth diaper for the twelfth time.

"Did I overhear my little fillies say they have morning munchies?" Celestia teased. Twilight giggled.

"Yes!" she squealed playfully, "Twily hungwy!" Applejack giggled as well, deciding to play along.

"AJ too!" she squealed. Smarty Pants nodded, still mesmerized by her new diaper. Celestia giggled as well.

"Well, shall we go on to breakfast?" she asked. Twilight smiled as Smarty Pants horsebacked her.

"Yes!" Twilight squealed. Applejack stood up, feeling her full diaper squish against her backside.

"Wait!" she said playfully, laying on her back, "AJ still poopy..." Celestia smiled and began to walk toward her, but Twilight stopped her.

"I'll do it," she said, "If Applejack doesn't mind." Applejack smiled.

"Sure, Twily," she said, "As long as mah stink ain't too strong fer ya."

"I think I'll live, AJ," Twilight said, giggling as Celestia smiled.

"Well then, go ahead," she said, "Just remember to wash your hooves before going to the table." Twilight nodded as Celestia nuzzled her, making her giggle as Celestia walked downstairs. Applejack hopped onto the changing table as Twilight grabbed the supplies and a spare diaper.

"Well, I didn't know mah pretend sis likes changin' diapers," Applejack said, resting herself comfortably on her back. Twilight chuckled and walked up to Applejack with the supplies, Smarty Pants sitting on the table next to the messy mare.

"Well, I'm just being a good pretend sister," Twilight said, "You may be here for only today, but you've been missing your diaper days for years, and I would be that great of a friend if I made you go home unsatisfied." Applejack blushed in flattery as Twilight began to change her best friend.

"Plus, I do owe you a bit," Twilight continued, "You made that diaper for Smarty Pants after she's been begging me for months to get her one."

"And I love it!" Smarty Pants said, "Now I feel like a real foal!" Applejack chuckled as Twilight stripped the tapes from her dirty diaper.

"Well, I like makin' other ponies happy, even if they're made o' cotton," she said, making Smarty Pants smile. Twilight changed Applejack in silence for a bit before Smarty Pants broke the silence.

"Eww!" she joked, playfully covering her muzzle, "You're such a ripe baby! And I thought Twily was stinky with a poopy diaper!" Both Twilight and Applejack laughed.

"Well, I guess I'm just a pretty big stinker then," she said as Twilight taped up the new diaper around waist.

"All done, AJ," she said. Applejack smiled as Twilight slipped her back into her onesie.

"Thank ya so much fer changin' mah stinky butt, Twily," she said.

"No problem," Twilight said, patting Applejack's padded behind, "Did I do it well?"

"Ya did perfect," Applejack complimented, "As long as I feel snug, and nuthin' leaks, it's perfect." Twilight blushed with flattery as Applejack hopped off the table. "Do you need a change too?" Twilight blushed a little harder.

"I... I may have... been pooping while changing you..." she confessed. Applejack caught the odor coming from Twilight's diaper and giggled.

"Looks like we've got another stinky foal in this Castle," she teased, making Smarty Pants giggle.

"Yeah!" she joined in, "Twily made a poo-poo!" Twilight blushed harder and hopped onto the changing table.

"Yes I did," Twilight said, "May I have a change as well?" Applejack smiled and nodded.

After Applejack finished changing Twilight, and Twilight gave Smarty Pants a pretend change, the mares all walked downstairs to the dining room. Plates and drinking glasses were already uncovered and filled, and Celestia was sitting in her chair, having not touched anything, wanting to eat with her pretend daughters. Twilight and Applejack sat across from her in two of the other chairs, and Smarty Pants sat on the table in front of Twilight.

"Sorry for being so late, Mommy," Twilight apologized, "We didn't realize how much time we wasted up there."

"Plus, Twily made an accident in her diaper and needed a change too," Smarty Pants added.

"That's quite alright, my fillies," Celestia calmly said, "Everything is still warm, and I have not started yet. All is forgiven." Applejack smiled.

"Thank ya, Mama," she said. She then looked at her plate, smiling wide at the pancakes and hashbrowns. "Oh yeah, chow time!" She dove right into her food like a dog. It seemed like she had eaten about three-quarters of her pancakes in one bite before the sound of a throat-clear stopped her.

"AJ," Celestia said, "I understand if you like your breakfast, but you are enjoying your meal with the presence of Royals, so please, use your table manners." Applejack nodded and swallowed what was in her mouth as Celestia levitated her napkin over to Applejack.

"Mah apologies, Mama, Twily," she said, wiping her face with the napkin. Twilight and Smarty pants giggled as they and Celestia began eating.

"So, Smarty Pants," Twilight whispered to Smarty Pants, "What do you think of Applejack, hmm?" Smarty Pants looked up at her sister, nibbling on a tiny strand of hashbrown.

"She's wonderful, Twily!" she happily said, "She's funny, playful, and kind! And she made me my first diaper!"

"So, would you say she's better than 'Dashie'?" Twilight asked. Smarty Pants gave Twilight a nonplussed look.

"Do you really have to ask me that, Twily?" she asked, "Let this answer your question." Smarty Pants raised her hind leg and made a raspberry-noise with her tongue, making Twilight giggle.

"I get it, Smarty Pants," she said, hugging her, "Anyway, AJ is a great playmate. In fact, I'd play foal with her as many times as I could." She whispered even lower. "I'd even let Pinkie Pie join us once we decide to confess to each other."

"Why, thank ya, Twily," Applejack said, having heard everything but the low whisper, "Pardon me fer sneakin' into yer conversation, but I didn't know y'all liked me around that much." Twilight smiled.

"Well, you are a good friend, but your a better playmate," she said, hugging Applejack, who blushed heavily.

"Aw Twily..." she said, "...yer makin' me blush now..." Smarty Pants giggled and joined in the hug.

"I like AJ..." she said. Celestia smiled with a blush as the fillies continued to hug.

"Also," Applejack said, "When y'all were talking about 'Dashie', did y'all mean Rainbow Dash?" Both Twilight and Smarty Pants nodded. "So she has the same fetish?"

"Heck no!" Twilight said, "Mommy had to completely erase her memories and regress her to get her to play along." Applejack laughed.

"Oh mare, I wish I coulda seen that!" she said, "Dashie actin' like a baby?! That'd be so priceless!"

"Well, she wasn't such a nice sister..." Twilight said, "...after what she did to me and Smarty Pants, I'd never want to play foal with her anymore..."

"She pulled my eyes out and blackmailed Twily with pulling out my tail to help her sneak cookies out of the kitchen..." Smarty Pants explained, "...and Twily got spankies for it..."

"Aww..." Applejack said, comfortingly hugging Twilight, "...well, I'd never do somethin' so cruel to y'all... I'm yer best friend fer a reason, and I wanna make sure I deserve to be yer best friend." Twilight smiled.

"Thank you, AJ," Twilight said, "You can bet we're gonna have our own foal time once Mommy's had her fun with me."

"And I'll be lookin' forward to it, Twily," she said.

"What about me...?" Smarty Pants asked, giving a pleading look. Twilight giggled.

"Of course you can join us, Smarty Pants," she said, cuddling her sister, "It wouldn't be the same without you." Smarty Pants smiled and snuggled into Twilight's coat as everyone finished their breakfast simultaneously.

"Did everyone get enough to eat?" Celestia asked.

"Eeyup!" Applejack said, "I mean, the portion was a bit smaller than I'm used to, but I love me a good ol' pancake!"

"Me too!" Twilight agreed. Celestia chuckled.

"Well, I'm glad everyone got enough," she said, smiling kindly, "Now unfortunately, I must attend six hours of Day Court in ten minutes."

"Aww..." Smarty Pants whined, "But I wanna play with you, Mommy!"

"I understand," Celestia said, "But I must attend these six hours or I'll just have to attend twelve hours tomorrow morning, and I'd much rather attend six hours than twelve. In the meantime, you can enjoy a little playtime in my chambers, and I'll be there once it's over."

"That's A-OK, Mama," Applejack said, "I'm sure Twily, Smarty Pants and I can find somethin' to do while we wait on ya. In fact, I brought a case o' Legos I'm sure ya'd like." Twilight smiled happily.

"I absolutely love Legos, AJ!" she said, "Let's go!" Celestia giggled and got up from the table.

"Well, you two go have fun," she said, "I'll be up there in six hours."

Twilight, Applejack, and Smarty Pants nodded and walked upstairs, while Celestia went to court. Once everyone reached the chamber, Twilight used her magic to open the door. Applejack walked in, went into her saddlebag, and grabbed her box of Legos. Twilight then flew herself and Smarty Pants into the large playpen, using her magic to levitate Applejack into it. The second Applejack's padded rear end touched the padded floor of the playpen, she sighed and rested her back against the net.

"This playpen sure is a might comfy," she comfortably said.

"Thank you," Twilight said, "Mommy made it for my fetish, and she said I could have it once I'm ready to go back to Ponyville."

"Well, you know I'm definitely coming over for playtimes whenever we get back," Applejack joked, making Smarty Pants laugh.

"AJ's funny!" she cheered.

"Why thank ya, Smarty Pants," Applejack said, kissing Smarty Pants' cheek, making her blush, "Well, y'all ready to play with mah Legos?"

"Of course!" Twilight said.

"But I wanna tell y'all now," Applejack said, "These were mah third birthday present, and mah folks gave 'em to me, so please play with 'em nicely."

"You can trust Twily and me!" Smarty Pants said, "We play with Mommy's toys too, and we no hurt them!" Applejack smiled and poured the multicolored Legos in the middle of the three.

"Well, dig in!" Applejack said. Everyone began to play with the Legos. After ten minutes, everyone showed off what they had built.

"I made a Lego-sculpture of me!" Twilight said, showing it off, "A little something for Smarty Pants to play with if I'm not around." Smarty Pants blushed as Twilight gave her sculpture to Smarty Pants.

"I made a basket o' apples!" Applejack said, showing it off, "*giggles* Yeah. Maybe I love apples a bit too much."

"But there's nothing wrong with that," Twilight said, "They're what your cutie mark tells you." Applejack smiled.

"Well, that's the truth," she said, "Plus, we all know I'm better at harvestin' apples than makin' purty dresses." Both Twilight and Applejack giggled as Applejack looked at Smarty Pants. "What'd ya build, Smarty Pants?" Smarty Pants smiled and pointed to her Lego-sculpture.

"I made my own potty!" she said. She pulled her diaper down to her ankles, sat on the fake toilet, and crossed her legs comfortably. Both Applejack and Twilight laughed again.

"Very creative, Smarty Pants!" Twilight said through giggles, making Smarty Pants smile with proudness.

"But, how is that comfy?" Applejack asked, "Just steppin' on them Legos is one o' the worst feelin's ever, so how are ya not hurtin' while yer sittin' bare-bottom on 'em?"

"When you're made of cloth and cotton, nothing hurts you externally," Smarty Pants said, giggling, "You don't know how many times Twily threw me around or banged me on things like a drumstick to a drum or stepped on me or sat on me when she was a foal."

"Not that I meant to though..." Twilight added.

"Of course Twily," Smarty Pants agreed, "But, I'm still here today, and unless something happens to make my cotton exposed, I'm impervious to pain!"

"Well, arn't'chu a lucky pony?" Applejack said, ruffling Smarty Pants' mane, who purred like a kitten.

"Oh, excuse me, AJ," Smarty Pants said. She grunted and made another raspberry sound with her mouth, sighing. "I just made a poo-poo in my potty!"

"Really?" Twilight asked, "Can I see it?" Smarty Pants hopped off the toilet and showed off a brown Lego she had stuck in the toilet before she sat down.

"Well, I'll be," Applejack said, "Ya actually did it. Good job, Smarty Pants!" Smarty Pants proudly smiled.

"Thank you, AJ!" she said, nuzzling Applejack. She then looked at Twilight. "I guess that means I'm the big sissy now!" Twilight giggled.

"Yes, that does," she said, "You learned how to use the potty first, so you're the older one."

"Yay!" Smarty Pants said. She then hugged Twilight. "But, I wanna stay in diapers, like you."

"And I'm not gonna stop you from it," Twilight said, hugging Smarty Pants back. At the same time, Celestia had walked into the chamber, giving a pleasant sigh.

"Mama?" Applejack asked, "Arn't'chu a little early?"

"Yeah," Twilight said, "It's only been half an hour. Didn't you say it would take six hours?"

"Yes, I did," Celestia said, "But there was a shortage of cases, so therefore, I only had to attend thirty minutes of court."

"Well, that's wonderful!" Twilight said, "In fact, you're just in time to join us for Legos!"

"Oh, and Smarty Pants used the potty fer the first time, too," Applejack said, showing the fake toilet to Celestia, who chuckled.

"So she did," she said, "Well, congrats Smarty Pants. Somepony's growing up to be a big pony like her mother."

"But I don't wanna be a big pony yet," Smarty Pants said, "I'm a baby, like Twily."

"You sure are, Smarty Pants," Twilight said, hugging her. Celestia smiled as well.

"My apologies, Smarty Pants," she said, "Anyway, I was wondering if my fillies would like a little snack. Since you behaved at the table so well, I feel that you deserve one."

"Yay!" Smarty Pants cheered, "I want some!"

"Count me in!" Twilight said.

"Right b'hind ya!" Applejack said. Everyone climbed out of the playpen and followed Celestia downstairs and outside after Celestia grabbed a few bowls off of the kitchen-counter. Everyone settled in the backyard garden comfortably in a circle.

"Uh, Mommy?" Twilight asked, "Why are we outside for this? Shouldn't we be in the dining room for snack?"

"Well, yes," Celestia said, "But this is a little messy, so it's better to have outdoors."

"It's no hassle, Mama!" Applejack said, "I'm sure it'll still taste good outside." Celestia smiled and gave Applejack a bowl, and gave one to Twilight for her to share with Smarty Pants, keeping one for herself. Applejack and Twilight looked into their bowls, seeing a orange, lightly-burned mixture with a white chocolate crust along the top.

"Is this crème brûlée?" Smarty Pants asked, sniffing the bowl.

"Yes, Smarty Pants," Celestia said, smiling, "My personal favorite dessert, next to cake."

"Well, that explains why we have to eat it outside," Twilight said, smiling as well, "Enough to know Smarty Pants and I love this!"

"I don't think I've ever had this stuff b'fore," Applejack said, "But it smells pretty good."

"Well, you're about to have your life turned upside down!" Smarty Pants said, "Because crème brûlée is yummy!" Smarty Pants greedily slurped the thick brûlée from her and her sister's bowl.

"Hey, leave some for me, you greedy little pig!" Twilight said. Celestia and Applejack giggled and ate their own brûlée . After about five minutes of silent-eating, everyone finished their dessert, and Celestia collected their bowls.

"Wee-doggy!" Applejack said proudly, "That crème brûlée was hoof-lickin' good!"

"You said it, AJ!" Smarty Pants said, a glob of brûlée covering her muzzle, "I love crème brulee!"

"So do I, Smarty Pants," Twilight said, "Even though you ate most of it before I could even start."

"I can't help it, Twily!" Smarty Pants said, speaking through her hoof in her mouth as she was sucking any excess brûlée it, "Crème brûlée is really yummy, and I'm like a lion to a steak when it comes to that!" Celestia giggled and had the maids collect the bowls and spoons.

"Well, I'm glad everyone enjoyed it," she said, "I most certainly enjoyed it more while having it with my fillies." Everyone else blushed.

"Mommy~!" Twilight whined, "You're making us blush!"

"I can't help it Twily," Celestia continued to coo, "You three are much cuter when you're blushing." Applejack smiled through her blush.

"Why, thank ya, Mama," she said.

"Thank you!" Smarty Pants also thanked.

"A thanks from myself as well," Twilight added.

"You're all welcome," Celestia said, giving her signature ladylike bow at her fillies. Applejack yawned and stretched her hind-legs with a light moan. A loud, wet noise was heard as Applejack had accidentally passed gas from the relaxation. Everyone looked her way as she blushed and crossed her legs, using her tail to waft the smell behind her.

"P-pardon me, everyone..." she embarrassingly said, "I do that when I stretch sometimes..." Twilight smiled, not wanting Applejack to have to sit embarrassed because of a little gas. Twilight lifted her hind-leg and passed one of her own, hers slightly louder than Applejack's. Everyone then looked at Twilight. "Twily... did you just-"

"Yes, I did," Twilight said, not even bothering to waft her odor behind her, "And now we're both guilty." Applejack laughed and nuzzled her friend.

"Girls, while that is a natural bodily function, it's very rude to do that around other ponies, especially Princesses..." Celestia said. Both Twilight and Applejack looked at Celestia.

"Oh... right..." Twilight said. Before she could apologize however, Celestia raised herself into a small squat and farted as well, dominating both Applejack and Twilight in terms of length, sound, and odor.

"...unless that Princess does it as well," Celestia finished, wafting her gas toward her fillies rather than away from them. All three foals laughed seriously hard.

"M-Mommy farted!" Smarty Pants yelled, rolling on the grass. Celestia giggled as well.

"Yes, I did," she confidently said. Once Applejack recovered from her laugh-attack, the smell of Celestia's gas finally reached her, and kicked her right on the button as she scrunched up her face.

"Hoo-wee!" she exclaimed, covering her muzzle with her hoof, "No offense, Mama, but y'all stink! The hog-pen back at home smells better than yer fart!" Twilight sniffed as well, instantly regretting it.

"Oh gosh!" she exclaimed through a gag, covering her muzzle as well, "AJ's not kidding! Why does your fart smell so bad?!"

"Well, I am a very large mare," Celestia bragged, "Plus, I do love beans, broccoli, cheese, and onions. Maybe it's just a sign that I should eat less of those."

"Or none at all!" Smarty Pants said, Twilight covering her muzzle as Celestia laughed again.

"C'mon, Twily," Applejack said, her voice a bit nasally from her nose being plugged, "Let's go back upstairs and get away from this stinky little Princess." Applejack winked at Celestia to show she was just joking, who nodded approvingly. Twilight nodded as well and walked over to Applejack, who walked over to the door.

"Are you coming, Mommy?" Smarty Pants asked.

"I'm going to sit out here for a few more minutes," Celestia said, "Just to be sure my gas doesn't follow me back inside." Smarty Pants giggled and nodded as they all walked back upstairs.

~~~~~~~~~~

Later that night, after escaping Celestia's stinky cloud of death, everyone spent the day playing games and having snacks. After Twilight, Applejack, and Smarty Pants had a bubble bath together, Celestia gave Twilight and Applejack a quick feeding before bed. Applejack suckled her stomach full and slowly pulled away, licking away any stray drops.

"How was it, AJ?" Celestia asked, wiping the excess cream from AJ's lips.

"To be honest, that wasn't bad, Mama," Applejack said, "Even though it was a little uncomfy drinkin' it from you, it was just like drinkin' regular ol' milk. Actually, it was better than that!"

"Well, I'm glad you enjoyed it," Celestia said, kissing her cheek, "Twily loves it as well." Twilight blushed lightly.

"It's alright, Twily," Applejack said, nuzzling her sister, "I'm not gonna snitch on ya." Twilight smiled.

"Thank you," she said, nuzzling back.

"Alright, you two," Celestia said, "It's bedtime now. Please pack Applejack's Legos up so you two can turn in for the night." Both mares nodded.

"Yes, Mama," Applejack said. Twilight and Applejack cleaned the Legos out of the playpen and put them back into the box. Smarty Pants picked up the Twilight figure made for her and held it out to Applejack to put in the box. Applejack simply smiled.

"Ya know what, Smarty Pants?" she said, "Y'all can keep that." Smarty Pants blinked in surprise.

"R-really?" she asked, "But, you said your mommy and daddy gave you these."

"Well, I've got thousands more in this box," Applejack said, "So it ain't gonna hurt if I let'cha keep a couple of 'em."

"Oh thank you, AJ!" Smarty Pants said, repeatedly kissing Applejack's cheek.

"No problem, Smarty Pants," Applejack said, "Just have Mama put some glue on that so it doesn't come apart." Smarty Pants smiled abd nodded. "Alright, let's get some shuteye."

"Let's," Twilight agreed, "Right after I get changed. I'm wet right now." Celestia smiled.

"Then let's get you changed, Twily," she said. Twilight smiled and laid on the changing table. One change later, Twilight hoped off the changing table and joined Applejack in the crib. Celestia used her magic to tuck them in and kissed them on their cheeks.

"Goodnight my little fillies," Celestia said, turning off the lights and laying down on her own rug. Applejack, loving the soft feeling of the crib, fell asleep almost instantly. Twilight heard Smarty Pants yawned and smack her lips loudly.

"Is my little sister getting sleepy?" she whispered.

"Mm-hmm..." Smarty Pants said, "Our tag game took a lot outta me... not to mention I was dizzy after getting trapped in Mommy's stinky fart..." Twilight giggled. "...but, I'm gonna miss AJ... she was just as fun to play with as Pinkie was..."

"Well like I said, we'll have a slumber party with her once we go back home," Twilight said, "But for now, let's go to sleep." Smarty Pants nodded.

"Night-night, Twily..." she said sleepily, cuddling Twilight close.

~~~~~~~~~~

Applejack woke up to the sound of a rooster's crow the next morning at the crack of dawn. She groaned a little and sat up, feeling something squish underneath her, followed by a familiar smell. She looked underneath her blanket and saw that she was still wearing her onesie and her diaper was messy, just like it was when Twilight had woken up the previous night. She smiled, enjoying her own stink.

"Looks like Princess Celestia was nice enough to let me keep the onesie," she mumbled groggily. She then saw a letter sitting at the foot of her bed, wrapped in an orange ribbon. Applejack grabbed the letter, opened it, and read it to herself.

"Dear Applejack," she read, "Thank you so much for allowing me to treat you as mah own foal and playin' along with Twilight Sparkle. I understand ya accepted without a deal, but I felt very bad fer ya, knowing yer unfair past, so I've left ya a wonderful reward I'm sure you'll greatly enjoy. But remember, ya now know about Twilight's foal fetish, so ya must keep this to yerself and yerself only. Should you ignore mah orders and tell anypony else, I will revoke yer reward, and you will go with out one, and I strongly advise you listen to me, because it'll be a major disappointment if you lose it again. You're Princess, Celestia." Applejack looked at the letter in confusion.

"What reward is she talkin' about?" Applejack mumbled, "And 'lose it again'? I don't even know what she's talkin' about." That was when the door was opened, and two ponies, a mare and a stallion, walked in. The sight of the two surprised Applejack to her core.

"It's been a long time, Applejack," the mare said, smiling at her.

"M-ma...? P-pa...?" Applejack said with disbelief.

"Yes," the stallion said, "It's me, Apple Turnover."

"And Apple Cider," the mare said, "AKA, yer folks." Applejack looked back and forth at them.

"B-but... y'all were... killed..." she said.

"Princess Celestia brought is back from the Afterlife," Apple Turnover said.

"Y'all must've done somethin' really good fer her," Apple Cider said, "Princess Celestia wouldn't do that fer just anypony." Applejack burst into tears of joy and hugged her parents.

"I can't believe it!" she yelled, "It's been twenty-one years! I never thought I'd see y'all again!"

"We didn't think so either, Sugarcube," Apple Turnover said. Applejack let go of them, smiling through her tears.

"I've got so much to tell y'all!" she said, "I've been doin' so much better than I was when I was four!"

"Y'all can tell us over some chow downstairs," Apple Cider said, "But first, I think ya need a new nappy. Y'all are a might stinky." Applejack blushed lightly.

"Yes, Mama," Applejack said. Apple Turnover walked downstairs to start breakfast, while Apple Cider changed Applejack into a new diaper. As she received her change, she peeked out the window toward Celestia's Castle.

"Now I see what'cha were talkin' about," she thought to herself, "Well, I promise ya on my family's lives that I'm not gonna tell nopony else about it. If I gotta glue mah mouth shut, then I'll do it." Apple Cider finished changing her daughter and carried her downstairs to the kitchen.

"Thank ya so much, Princess," Applejack mumbled, "Now if y'all will excuse me, I'm gonna go catch up with mah folks."

Author's Note

Alright, now I know some of you are going to complain to me for not regressing Applejack, but go with me here.

Don't you think that some characters have good enough excuses for them not to be regressed? Don't you think Pinkie Pie not getting to enjoy her foalhood because of living on a rock farm half her life is a good enough reason? Don't you think Applejack losing her parents at an early age and being forced to give up her diapers when she wasn't ready to is a good enough reason?

Of course, Rarity and Rainbow Dash wouldn't have willingly done it. Rarity wouldn't approve of soiling herself like a foal, and Rainbow Dash couldn't drink out of a foal bottle if you put apple cider in it. That's why they were regressed. But Applejack and Pinkie Pie had good excuses, which is why I chose not to regress them.

Plus, I know Celestia resurrecting Applejack's parents was probably too big of a reward, but think about it. The only thing Applejack has stated she really wants is money to fix up Sweet Apple Acres, but Celestia giving Applejack money for acting like a foal seems a bit unfair to everyone else. Cloth, bakeries, and leadership isn't a good of a prize than money, so that's why I chose the return of Applejack's parents.

Anyway, Applejack's chapter has finally been completed. I know it took six months, but I had internet problems, and other stories to tend to, so that's why it took so long. I'll try not to take so long for the next chapter.

Now, Fluttershy is the only mare left, and then Spike will go before background/side characters can be selected. No need for a vote now, but be on the lookout for Fluttershy's chapter next. And just to set the record straight, Fluttershy will not be regressed either. You'll find out why in the next chapter.

Hope you enjoyed this chapter, and sorry for the delay!

P.S. In case you haven't guessed yet, yes. I'm a big fan of diapers, flatulence, and toilet humor, which is the only reason I had Celestia fart. If you think that was a bit immature and unladylike, than so what? Celestia a pony too, so I'm sure she's had her own gassy moments. If you want more Celestia farts, let me know! *wink wink*

Fluttershy

Twilight, once again, woke up when Celestia's beautiful sunlight shined in her face. Before she could open her eyes, she felt something slightly heavy draped over her, something furry in her face, making her smile.

"Good morning, Smarty Pants," she mumbled, thinking the doll was hugging her. But a small yawn from her side told her otherwise.

"What did you say, Twily...?" Smarty Pants mumbled, waking up as well. Twilight blinked her eyes open, but something pink and hairy was blocking her view. That's when it finally hit her that she wasn't alone at that point.

"Is that Pinkie Pie again...?" she said inside her head, too lazy to push whoever was on her off, "No... Celestia wouldn't do a repeat... and the pink is too light..." She thought for a minute, and then remembered that she had another friend with a pink mane. "If it's not Pinkie, then it has to be..." She brushed the pink mane out of her face.

"...Fluttershy!" she finished aloud. Sure enough, Fluttershy was gently laying over her, cuddling into her onesie. Fluttershy, after hearing Twilight say her name, let go of her.

"Hi Twilight..." Fluttershy said in her usual timid tone of voice. Twilight sat up and looked at her best friend. Fluttershy was dressed in a yellow dress that was a little short for her, which exposed the bottom of her white diaper, which had a bit of a yellow tint to it, indicating she was wet.

"Hi... uh..." Twilight said, "What's your name...?" Fluttershy giggled.

"It's still 'Fluttershy', silly," she said, "I didn't ask to be called anything specific..." Twilight smiled.

"So, you're not regressed either, hmm?" she asked.

"No, I agreed to do this," Fluttershy said.

"Oh, I see," Twilight said, "Element of Kindness and whatnot, right?" Fluttershy blushed.

"Well... no..." she said, "I had other reasons..." Twilight raised her eyebrow.

"Other reasons?" she asked. Fluttershy nodded and was about to explain, but right when she opened her mouth to speak, Celestia flew in through the window, having just finished raising the sun. She saw Twilight awake and smiled.

"Good morning, Twily," she said, affectionately licking her cheek. Twilight blushed.

"Good morning, Mommy..." she said. "So... I take it Fluttershy's the next pick?"

"That's correct," Celestia said, "And as you probably saw, I didn't regress her."

"Yeah, she was just about to tell me why," Twilight said, picking up Smarty Pants and cuddling her.

"Oh, well a thousand pardons for my interruption, sweetheart," Celestia said to Fluttershy, "Please, carry on." Fluttershy nodded and cleared her throat.

"Well, it started last month," Fluttershy said, "I had to have my toilets removed because they were drowning hazards for my animals. So, that left me with wonders on how to dispose of my... excrement..." Twilight nodded.

"And...?" she asked.

"At first, I used the stables the animals use," she said, "But it was a little embarrassing with other animals watching me go, and after years of being toilet-trained, it was hard to just squat and... do my business..."

"I can understand that," Twilight said.

"So then, I decided to walk to Sweet Apple Acres and ask Applejack if I could use their outhouse if I needed to go," Fluttershy continued, "Even though they were nice enough to let me use it anytime, I still felt bad and that I was using my best friend for her outhouse. Plus, sometimes I desperately needed to go, and galloping quarter-mile doesn't help you hold it, especially if the outhouse is occupied when you get there..." Fluttershy took a small breath.

"And so... I started using diapers..." she finished up, "At first, I only used them when I really needed to go, and I couldn't make it to Sweet Apple Acres, because two years of potty-training and twenty-one years of being potty-trained made it awkward... but..."

"But it slowly started to grow on you, didn't it?" Twilight asked, "After filling your fifth or sixth diaper, you started liking it, didn't you?" Fluttershy blushed hard.

"...yes..." she said shyly, "...after a few stinky diapers... it was enjoyable... diapers on their own are already so fluffy and cozy... and the warm feeling you get when... well..."

"It's OK, Fluttershy," Twilight said, "I understand. So that's how you developed a diaper fetish?"

"Yes..." Fluttershy said, "...I love diapers now..." Celestia smiled and nuzzled her.

"So, that's why I chose her next," she said, "She too has a diaper fetish, but unlike Applejack, she has a happy reason for liking them." Twilight nods.

"But, what are your takes on foal fetish?" Twilight asked, "Like drinking from bottles or suckling pacifiers or playing with toys...?"

"Well, that is new to me, Twilight," Fluttershy said, "But I'd do anything if it meant for a friend to be happy." Fluttershy nuzzled Twilight, making her blush. Twilight really liked Fluttershy, but there was something about Fluttershy that made Twilight like her a bit more than her other friends.

"W-well... thank you... Fluttershy..." she said. Fluttershy giggled as Celestia smiled.

"Well, Mommy has to go to court now," Celestia said, "I only have two hours today, so I'll be back in no time." She kissed both of their cheeks. "If you get hungry, you may help yourself to anything in the kitchen."

"OK Mommy..." Twilight said, "Have fun..."

"I'll try," Celestia said, giggling and walking out of the room, leaving the fillies alone.

"Hey, how come you're wearing a dress instead of a onesie?" Twilight asked, "They're a lot more comfy."

"Yes, I understand," Fluttershy said, "But onesies are made of flannel, and flannel is made of wool... so out of respect for sheep, I decided not to wear one."

"Oh, I see," Twilight said, "I forgot you're completely vegan." Fluttershy smiles and nods.

"Yes," she said, "I love animals very much, and I'd never wear anything made of animal fur or skin." Fluttershy shifted uncomfortably. "But, my wet diaper is getting a little cold." Twilight smiled.

"Would you like a change?" she kindly asked. Fluttershy blushed in shyness.

"Oh... my..." she said, "Are you sure...? I can change myself..."

"Of course I'm sure," Twilight said, "It's easier to have somepony else change you than changing yourself." Fluttershy smiled.

"Well... if you insist..." she said, Twilight smiled and carried Fluttershy to the changing table. Fluttershy yelped at the sudden lift, on account of her acrophobia, but she calmed down once she realized Twilight was carrying her. Twilight laid Fluttershy down, lifted her dress, and changed her diaper.

"So... uh..." Fluttershy said, a light blush of embarrassment on her face, "...when did... you start enjoying foal-play...? I-if you don't mind me asking...?"

"I don't mind," Twilight said, grabbing a box of baby wipes, "Well, it pretty much started after Princess Celestia granted my royalty. I used to read books and turn in reports, but being a Princess is much more time-consuming and difficult. It used to stress me out horribly, but I read in a book that foal-play can be a wonderful stress-tamer."

"Oh, interesting," Fluttershy said, grunting in discomfort at the coldness of the wipes, "So that's *eep* why you enjoy *ah* it?" Twilight finished wiping Fluttershy and placed a new diaper underneath her bottom.

"Well, not exactly," Twilight said, "See, I told myself only to pretend to be a filly during times of stress, and only when I absolutely need to, but I did give into it a little more than that." Fluttershy giggled.

"I understand," she said as Twilight taped up Fluttershy's new diaper and pulled her dressed back down, "It just became too irresistible, and you loved it." Twilight smiled.

"Yes, exactly," she said. Fluttershy sat up and slid off the table, landing behind her friend. That's when a pungent, but familiar smell traveled under her muzzle, and it wasn't a mystery where it was coming from.

"Um... Twilight...?" Fluttershy asked, "Do you... need a change as well...?" Twilight blushed as well.

"I may be a little messy..." she said. Fluttershy smiles and patted the changing table.

"Hop up, please," she said. Twilight smiled and settled herself on the table, squishing the contents of her full diaper accidentally. Paying to mind to it, Fluttershy changed Twilight with a smile. The foul smell emanated between the two, making Twilight blush harder.

"I'm sorry if that's a little too stinky to you..." she said with a babyish accent, sitting up slightly to look at Fluttershy, who giggled lightly as she powdered her friend's crotch.

"It's OK," Fluttershy said, "I live with 500 animals, so this is the last smell that's going to make me cringe."

"Wow..." Twilight said, resting her back against the padded table again, "And I thought Spike had the strongest nose in Equestria..." Fluttershy giggled again as as taped up Twilight's new diaper.

"All done, Twilight," she said, buttoning up the flap to her onesie. Twilight hopped off the changing table and stretched.

"Thank you, Fluttershy," she said, nuzzling her friend.

"You're very welcome, Twilight," Fluttershy said with a smile.

After a few hours of playing with some Legos and blocks, the fillies were reunited with Celestia, who had just finished her court. Everyone played with the toys for another hour until a simultaneous growl from everyone's stomachs told them it was time for something else.

"Looks like it's lunchtime," Celestia said with a smile.

"Yay!" Twilight said happily, having just finished brushing Smarty Pants' mane and tail. "I'm so hungry I could eat a Castle!" Celestia laughed.

"Well, don't eat my Castle, Twily," she joked, making Twilight laugh harder. Fluttershy laughed as well, accidentally wetting herself as a result.

"Mommy... I'm... wet..." she said between giggles and breaths. Celestia smiled and lifted Fluttershy onto the changing table.

"You may go on to the dining room, Twily," she said, "Fluttershy and I will meet you down there." Twilight nodded and walked downstairs to the dining room, taking Smarty Pants with her.

"Hey Twily," Smarty Pants said, tucked comfortably into Twilight's wing.

"Yes, Smarty Pants?" Twilight asked, sitting down in her chair and sitting Smarty Pants next to her.

"Thank you for doing my hair," she said, happily caressing it, "I finally look like a Princess again."

"You're welcome, Smarty Pants," she said, "I'm always happy to help." Smarty Pants smiled.

"And Fluttershy is fun and sweet!" she continued, "She's almost more fun than Pinkie and Applejack!"

"You know, I was thinking the same thing..." Twilight said, "And besides... I do really like Fluttershy..." Smarty Pants giggled.

"Yeah, I know..." she said, "You really like Fluttershy, even more than books."

"Yes... but it's still our little secret OK...?" Twilight said.

"It's still our secret, Twily," Smarty Pants said. After about five minutes, Fluttershy and Celestia made their way to the dining room. Fluttershy sat next to Twilight, and Celestia sat across from the two.

"Hey Twily...?" Smarty Pants said, "May I sit with Fluttershy this time please...? She's cuddly..."

"Well, of course you may," Twilight said. Smarty Pants smiled as Twilight lifted the doll and held it out to Fluttershy. "She wants to sit with you." Fluttershy smiled and grabbed her, sitting her in her lap.

"Hello, Smarty Pants," she said, "It's nice of you to sit with me." Smarty Pants smiled and hugged her.

"Yay!" she said. Fluttershy giggled as one of the many maids brought out lunch. It was a raspberry vinaigrette salad and French onion soup. Fluttershy smiled at her lunch, but it made Twilight raise her eyebrow.

"Uh... is that it...?" she asked.

"Oh my, I forgot to inform you, Twily," Celestia said, "Fluttershy asked me to inform the cooks to make soup and salad only, out of respect to her veganism." Fluttershy nodded to prove it.

"I'm sorry, Twily..." she apologized with a shy blush. Twilight smiled and scooted her plate and bowl a little closer to her.

"It's fine, Fluttershy," she said, "Anything for a friend." Fluttershy smiled and ate her lunch, Celestia doing the same.

"Hey Fluttershy," Smarty Pants asked, "What's it like living with so many animals?" Fluttershy smiled.

"Well, it's wonderful," she said, slurping her soup, "Everyone loves me and we're always doing fun things like picnics and sleepovers. Even though they can get a little wild, it's still fun."

"Wow!" Smarty Pants said.

"Do you like animals, little one?" Fluttershy asked.

"Mm-hmm!" Smarty Pants said, "I love animals! Twilight reads me bedtime stories about animals all the time, and we always sit in the backyard and watch birds and squirrels that come by!"

"Aww, that's wonderful!" Fluttershy said, kissing her cheek, "What's your favorite animal, Smarty Pants?" Smarty Pants smiled, eating a piece of lettuce Fluttershy fed her.

"Kitties!" she said, "I LOVE kitties! I want a kitty soooooo bad..." She pouted and crossed her front legs. "...but Spike is allergic to kitty-dander... and Twily won't let me have one..." Twilight looked down, then at Fluttershy.

"It... it's not like I wouldn't let her have one if I could..." Twilight said, "...but Spike's allergies nearly killed him last time... and he almost set fire to the Castle with his sneezing..."

"It's alright, Twily," Fluttershy said, nuzzling her friend. She then looked at Smarty Pants again. "Well, you're always welcome to come by the cottage when you like. I've got plenty of kitties that I'd be happy to let you play with."

"Really?" Smarty Pants asked.

"Of course," Fluttershy said, "I'm always happy to let my friends play with my animals."

"Yay!" Smarty Pants yelled, "Twily! Can we go to Fluttershy's house when we go back to Ponyville?"

"Of course we can, Smarty Pants," Twilight said with a smile. Smarty Pants squealed in joy and hugged her sister hard.

"Thank you, Twily!" she said, burying her muzzle in her coat. Twilight smiled and hugged her back.

"I'll be waiting for you two," Fluttershy said. After everyone finished lunch, Celestia had everything cleaned up and the table cleared.

"Did everyone enjoy everything?" Celestia asked the fillies.

"It was delightful," Fluttershy said. Smarty Pants ate the last bit of salad from Twilight's plate, making her giggle.

"I agree," Twilight said. Celestia wiped her mouth with her napkin and set it on the table.

"Well, now that our tummies are full, what would you like to do now?" she asked. Fluttershy thought for a minute.

"Hmm... well... um..." she mumbled to herself. Twilight smiled and answered for her.

"How about we go to the zoo, hmm?" she asked, "It's free on Saturdays."

"Well, that sounds quite delightful," Celestia agreed, "Fluttershy, would you like to go to the zoo?"

"I'd love to," Fluttershy said with no hesitation, "I haven't seen my animals yet today, so it'd be nice to see some."

"And I wanna see the aquarium!" Smarty Pants said, "The angelfish there are so colorful!" Both Fluttershy and Twilight laughed, while Celestia smiled.

"Then it's settled," Celestia said, "We'll go to the zoo."

"Yay!" the three fillies simultaneously said.

"But first, I must take a quick shower, and Twilight, you must change into your dress." Twilight nodded.

"Yes, Mommy," Twilight said, "C'mon Smarty Pants. Let's go change." Smarty Pants nodded and held her hooves out to her. Twilight grabbed her and carried her upstairs, Celestia following, while Fluttershy sat patiently at the table, drinking the wheatgrass-smoothie she previously asked for with her lunch.

After Celestia had showered and Twilight had changed from her onesie to her lavender dress, Twilight and Smarty Pants joined Fluttershy, who had just finished her smoothie. Celestia grabbed the stroller from the closet and filled the diaper-bag with the supplies she needed. Once she was ready, she strapped the diaper-bag to her side and walked back into the dining room, the stroller being pulled with her magic.

"Alright Fluttershy, Twily," she said, "Come get in the stroller so we can get going."

Fluttershy and Twilight smiled and settled themselves comfortably in the carriage. Celestia draped a fluffy cotton blanket over the two, pulled the sun-blocker out, and began walking to the zoo, pushing the stroller with her. Twilight snuggled Smarty Pants, sighing in comfort, while Fluttershy sang to herself quietly, playing with the bottom of her dress to keep herself entertained.

Twilight blushed lightly at the soft sounds of Fluttershy's singing. Even though her lyrics were only "la-la-la," they were still wonderful to Twilight's ears. That was another thing Twilight liked about Fluttershy. Her singing was like magic, no matter what she was singing about. Twilight sat there with a blush on her face, listening to Fluttershy's soothing singing. Once Fluttershy stopped singing for a bit, Twilight scooted a little closer to her.

"Uh... Fluttershy...?" she asked timidly, almost as low as Fluttershy's normal tone of voice.

"Yes, Twily?" Fluttershy asked, looking at her friend.

"Do you mind if I... cuddle you...?" Twilight asked, "I'm a little cold..." Fluttershy smiled.

"Of course you may," she said, "I love cuddles." Twilight smiled and snuggled into her best friend's coat, loving the slight banana scent of her coat. Fluttershy blushed as well, nuzzling her friend.

"You're very affectionate, Twily," she said.

"Well... you're really cuddly..." Twilight said, "Plus... you deserve a hug for agreeing to play along with me..." Fluttershy smiled as Twilight continued to hug her in silence.

"And..." Twilight continued, "Your singing is wonderful..." Fluttershy smiled, her blush growing a little redder.

"Thank you, Twily..." she said, kissing her cheek. The cheek-kiss made Twilight blush so much harder than she had ever blushed in her life. Twilight felt her heartbeat increase, and she knew there was something she needed to say.

"Fluttershy...?" she asked, "I..."

"What is it, Twily?" Fluttershy asked.

"There's something I have to tell you..." Twilight said, holding Fluttershy's hoof, making her blush a little harder.

"Oh... my..." Fluttershy said.

"Fluttershy..." Twilight said, "I... I... I have... uh..." Before Twilight could get it out, they had already reached the zoo.

"We're here, my little fillies," Celestia said. She pushed the stroller into the locker room and helped Twilight, Fluttershy, and Smarty Pants out of the stroller. She then folded the stroller, chose a locker, and placed the stroller inside, along with the blanket.

"I think you'll have more fun if you can explore the zoo on your hooves," Celestia said. The fillies nodded. "Alright, which exhibit should we visit first?" Fluttershy smiled.

"Could we go to the butterfly room first, please?" she asked, "I love it when the cute little butterflies give me kisses on my muzzle."

"Alright then," Celestia said, "We'll go there first." Celestia walked to the butterfly room, Twilight and Fluttershy following.

"Twily?" Fluttershy asked, "What were you going to ask me in the stroller...?" Twilight gulped.

"Oh... uh... it was nothing..." Twilight said.

"Are you sure?" Fluttershy asked, "It sounded a little serious..."

"It's just something I'd now like to keep to myself, OK...?" Twilight said.

"Alright then, Twily..." Fluttershy said, "But if you decide to tell me, I'll listen." Twilight nodded.

For the next hour, the mares enjoyed their time at the zoo, looking at several exhibits and visiting the aquarium for Smarty Pants to see the angelfish she loves. At that point, with Celestia in the restroom, Fluttershy and Twilight were at the skunk exhibit.

"They are so precious," Fluttershy said.

"Yeah, but I've still got a few bones to pick with skunks, ever since last year's Winter Wrap-Up," Twilight said. Fluttershy tried really hard not to laugh, but stifled a little giggle.

"Well, even the stinkiest of animals can still be cute and adorable," Fluttershy said, Smarty Pants nodding in agreement.

"I don't mind the stink," Smarty Pants said, "I sat in the bathroom with Twilight when she was being potty-trained, and she was one big stink-bomb."

"Hey!" Twilight whined. Fluttershy giggled again. Right then, Fluttershy spotted a note taped next to the Skunk Information at the front of the habitat. She glanced at it and scanned through it, instantly wishing she hadn't.

"Oh no!" she yelled.

"What's wrong, Fluttershy?" Twilight asked, "Do you need a change?"

"No!" Fluttershy yelled, "Even worse!" She pointed to the note. Twilight quickly scanned though it.

"Huh?!" she exclaimed, "Canterlot Zoo is going bankrupt?!"

"Can I help you, little fillies?" a zookeeper asked them.

"The zoo is going bankrupt?!" Fluttershy asked.

"Unfortunately, yes," the zookeeper said, "Nopony is as interested in going to the zoo anymore, and the owner is getting older. We can't afford to keep the zoo much longer."

"But what will happen to the animals?!" Fluttershy worriedly asked.

"Well, some will be taken to their natural habitats, and some will have to be put down," the zookeeper said.

"Put down?!" Fluttershy squealed.

"Yes," the zookeeper said, "It would cause too much buildup if we were to drop all of our animals off into nature..." Fluttershy gasped, a tear coming to her eye. The one thing that made her sadder than anything else was the thought of animals being killed.

"There must be something I can do to help!" she said.

"Well, we are taking names to help contribute to the zoo," the zookeeper said, pointing to a box full of strips of paper, "We'll be selecting the winner tomorrow, and the winner will be rewarded ownership of the zoo, if they present proof that they can be trusted around innocent animals. But if the winner rejects ownership or does not have the valid proof we need, then the zoo will be forced to shut down."

"I'll enter!" Fluttershy said.

"Well, sign your name and age, and then put the paper in the box," the zookeeper said, "And hope that you'll be chosen tomorrow."

Fluttershy nodded worriedly and quickly did just that. She then stuffed her paper into the bottom of the box, fearing the wind would blow her paper away. The zookeeper smiled at her.

"Good luck," he said, before walking away. Twilight walked over to Fluttershy with a slight smile.

"That's very kind of you, Fluttershy," she said, "You're definitely going to get chosen." Fluttershy couldn't say anything, as she looked down at the ground, a saddened look on her face. The thought of animals being put down was the one thought that could instantly hit her in her soft spots.

"Fluttershy?" Twilight asked. Fluttershy continued to look at the ground. "You don't have to look so sad... tomorrow, it could be you owning this zoo, and the animals would be safe..." Twilight caught a tear leaking out of Fluttershy's eye. She couldn't help but hug her friend.

"Hey... how about we go to the bunny cages, hmm...?" she suggested, "Maybe the zookeepers will let you cuddle one..." Fluttershy sniffled and smiled.

"Yes... that'd make me feel better..." she said. Twilight smiled and turned her diapered read end toward Fluttershy.

"I'll carry you there if you like," she offered. Fluttershy smiled and climbed onto Twilight's back, comfortably positioning herself.

"Thank you, Twily..." she said, kissing her cheek again. Twilight blushed hard and walked to the bunny cages.

~~~~~~~~~~

After the day at the zoo, Fluttershy finally cheered up and she and Twilight were sitting in the playpen, playing with some Lincoln logs and connecting cubes, while Celestia was downstairs, making cookies for herself and the fillies. Twilight had just finished sculpting her own Castle with the logs.

"All done," Twilight said. Fluttershy smiled.

"What a wonderful Castle, Twilight," Fluttershy complimented.

"Thanks, Fluttershy," Twilight said, "What did you build?" Fluttershy showed Twilight the little animal figures she made out of the connecting cubes.

"I just made a few animal figures," she said, "This is a bunny, this is a squirrel, this is a skunk, and this one is a blue jay."

"Hm, not bad," she said, "They'd look just like the real things if they weren't square."

"Yes, I agree," Fluttershy agreed, "If only toy stores could make connecting spheres." Twilight laughed hard.

"Oh Fluttershy! You're so funny!" Twilight said. Fluttershy smiled, a light blush on her face. After Twilight stopped laughing, the smell of something foul attacked her muzzle, which was just teetering over the limit to make her cringe. "Huh...? What's that smell...?" Fluttershy blushed a little harder, raising her dress up, showing Twilight her freshly-messed diaper.

"Sorry, Twily..." Fluttershy said, "...I pooped myself..." Twilight saw the embarrassed look on Fluttershy's face.

"Hey, it's alright, Fluttershy," Twilight compassionately said, "You're a baby. It's not like you could get to the potty in time." Fluttershy blushed harder and giggled. "So, do you want me to change you, or do you wanna stay stinky for awhile."

"Hmm..." Fluttershy thought for a minute, "Well... I did just mess it... and the feeling is a little warm... so... I think I'd like to keep my messy diaper for now..."

"Alright then," Twilight said, "When you want a change, let me know." Fluttershy nodded as the door was opened by Celestia's golden aura. Celestia then walked in, carrying a few plates of cookies and two bottles of milk.

"Whose ready for sweet-sweets?" Celestia teased. Twilight and Fluttershy both eagerly flew out of the playpen and sat on the sofa.

"Me!" Twilight squealed.

"I am!" Fluttershy squealed. Celestia smiled and levitated the plates off of her back.

"Alrighty," Celestia said, "We have sugar cookies for myself, peanut-butter-chocolate-chunk cookies for Twily..." Celestia used her magic to give Twilight her cookies.

"Thank you, Mommy," Twilight said.

"You're welcome, Twily," Celestia said, grabbing the last plate, "...and oatmeal raisin cookies for our vegan guest." Fluttershy smiled and took them.

"Thank you, Mommy," Fluttershy said, ignoring the mushy feeling in the back of her diaper.

"You're welcome, Fluttershy," Celestia said. She then set a glass of milk on the table for herself, and gave a bottle of her own breast milk to Twilight. "And Fluttershy, I wasn't sure what to get you to drink along with your cookies, since you don't drink milk. So, I went out and found some completely organic and vegan foal formula, and I figured you'd like it." Fluttershy smiled and took it.

"Thank you," she said.

"You're welcome," Celestia said, "If you don't like it, then you don't have to finish it." Fluttershy nodded as everyone ate their cookies silently. Fluttershy sipped her formula timidly, Twilight seeing this.

"How is it, Fluttershy?" she asked. Fluttershy smacked her lips, letting the taste marinate with her taste buds. Her eyes popped open in surprise.

"W-wow... this tastes wonderful!" Fluttershy said happily. Twilight was surprised.

"Really?" she asked.

"Yes!" Fluttershy said, "It's very sweet, and there's no chalkiness texture!" Fluttershy suckled her bottle for a few seconds, making Twilight curious.

"May I try some...?" she asked. Fluttershy smiled and held her bottle out to her friend.

"Of course you may," she said. Twilight took the bottle and took a small suckle of her own. Sure enough, the taste was just as Fluttershy described.

"Woah!" Twilight said, "This is foal formula?!"

"It is," Celestia said, "Organic and vegan."

"Wow!" Twilight said, drinking more, "I never knew foal formula was so delicious!" Fluttershy took the bottle back and drink some more as well.

"I agree," she said.

"Once I get back to Ponyville, I'm definitely going to find some of that!" Twilight eagerly said.

"That would be a wonderful choice," Fluttershy said, holding her bottle out to her friend, "But for now, we can share my bottle." Twilight nodded with a smile and took it back. Right after finishing their cookies, Twilight gave a wet fart and began to mess her diaper with a devious smile.

"Oops," she sarcastically said, "I had an 'accident'." She giggled, Fluttershy giggling as well as she finished her last cookie.

"Now we're both messy!" Fluttershy squealed in a babyish tone. Celestia smiled and finished her last cookie as well.

"Alright, my stinky little fillies," she said, "Let's get you two changed so you can go sleepy. Mommy's getting sleepy herself." Twilight smiled and hopped onto the table.

"Me first!" Twilight squealed. Fluttershy smiled.

"You go ahead," she said, "I need to make more poo-poos anyway." Celestia smiled and changed Twilight's diaper, while Fluttershy began to mess her diaper again, adding onto the previous mess. Once she finished, and the bulge in the back of her diaper grew twice as big, Celestia had finished changing Twilight.

"All done, Twily," Celestia said, kissing Twilight's cheek.

"Thank you, Mommy," Twilight thanked her, hopping off the table. Celestia then picked up Fluttershy and laid her on the changing table.

"Oh my!" Celestia said, playfully covering her muzzle, "My filly is a really stinky filly, isn't she?" Fluttershy blushed.

"Sorry... I really had to go again..." she said timidly.

"Mommy's just joking, Fluttershy," Celestia said, kissing her cheek, "No need to become embarrassed." Fluttershy smiled and nodded. After Fluttershy was changed, Celestia placed them both in the crib, tucked them in, and turned off the light.

"Goodnight, my little fillies," she said, "Sweet dreams." Celestia laid down on her rug as Fluttershy scooted closer to Twilight, snuggling close to her.

"Do you mind if I snuggle with you...?" she asked, "I get cold easily..." Twilight smiled.

"Go ahead..." she said, kissing Fluttershy's forehead. Fluttershy blushed and giggled.

"Thank you... Twily..." Fluttershy mumbled, slowly falling asleep. Twilight smiled and cuddled her friend close, slowly falling asleep as well.

~~~~~~~~~~

Fluttershy woke up to the feeling of something rubbing against her face. She opened her eyes and saw that she was in her own bedroom, and her bunny assistant, Angel, was nuzzling her awake like every morning. She smiled and pet the top of his head, making his left hind leg stamp on her stomach.

"Thank you for waking me, Angel," she said. She yawned quietly, then rubbed her eyes. "Alright, give me a minute to wake up, and I'll make you some breakfast." Angel smiled and hopped off. Fluttershy sat up and saw a scroll wrapped in a yellow ribbon sitting on her nightstand. She picked it up and placed her reading glasses over her eyes, reading quietly to herself.

"Dear Fluttershy," she read, "Thank you so much for allowing me to be your temporary mother and playing along with Twilight Sparkle as an adult foal. Now, I understand you accepted without a gift in return, but I gravely insisted, as I overheard a certain conversation you were involved in yesterday. But be advised that you now know about Twilight's foal fetish, and you mustn't tell another soul about this. Should you disobey me, your reward will be taken from you. Your Princess, Celestia."

"Oh... my..." Fluttershy said, "That's very kind of her... but... I wonder what reward she's talking about..." Right then, there was a knock at the door. Fluttershy yelped at the sudden sound, but quickly threw her robe on and walked downstairs, opening the door. To her surprise, standing at the door was the zookeeper from the previous day.

"Good morning, Ms. Fluttershy," he said.

"Oh my... Mr. Zookeeper... hello..." she said, "How can I help you...?" He smiled, showing her the paper she signed yesterday.

"I'm happy to announce that you have won the new position of owner of Canterlot Zoo," he said. Fluttershy's eyes went big.

"E-excuse me?!" she said in surprise.

"You are now the new owner of Canterlot Zoo, Ms. Fluttershy," he repeated.

"B-but... what about the proof and other things you said were required?!" she said, "Shouldn't you check for that first?!" He smiled and looked past her and into her house.

"Judging by the many animals you possess, I believe you more than qualify for the position," he said.

"Oh... oh my..." Fluttershy said, "I... I..." She finally smiled. "I'd love to own Canterlot Zoo, Mr. Zookeeper!" He smiled.

"Well, come to Canterlot by 7:00 PM tonight to pick up the legal documents," he said, "And then, you'll officially be the new owner."

"Wonderful!" she squealed, "Thank you, Mr. Zookeeper!" The zookeeper smiled and walked away. Fluttershy smiled.

"...and thank you... Princess Celestia..."

Author's Note

OK, I know most of you are getting sick of waiting so long for new chapters, so now, I've decided to completely dedicate most of my time on this story, as this is my mostly-noticed story.

Now, I know most of you are going to complain that I already used the diaper fetish excuse on Applejack, but that was for a totally different reason. I'm sure I'm not the only person who thinks Fluttershy uses her own poop for fertilizer.

Also, I'm sure most of you are going to complain that Twilight's chance to open her heart to Fluttershy went nowhere, but hang in there. Things on that subject will bloom again, I promise.

OK, all five members of the Mane Six have been chosen, and Spike will go next. But, here's how I'm going to do the next voting:

As you comment, leave a name for a background/side character, and the top five that gets mentioned the most will be selected for next voting session. (During the next voting session, once a background/side character is chosen for the next chapter, a new one will take its place, so there will always be a new name in the polls)

Get to naming, and hope your character will be picked!

Spike

Twilight woke up the next morning to a very foul smell once again. She groaned, her eyes still closed, and placed her hoof over her muzzle. She reached down to poke her diaper, but it was just wet. In fact, the foul stench didn't even smell like a dirty diaper to her. It smelled like something far more worse than that.

"Ugh... what is that nasty smell...?" she mumbled to herself, "...that can't be a poopy diaper..." She sniffed again, fighting back a gag. She rolled over, her muzzle bumping against something fleshy and scaly, the smell becoming stronger as she did. It was at that moment that the smell became familiar, as she had smelled it so many times. And the scaly feeling was familiar as well. After putting two and two together, she finally realized what the smell was.

"Of course... the bad smell... the scaly feeling..." she mumbled, "...that definitely has to be..." She opened her eyes, seeing a pair of purple dragon feet in her face. She squealed and rolled away from them.

"...Spike's stinky feet!" she squealed. She sat up and sure enough, sitting on the rug, was Spike, her purple dragon assistant. He was wearing a green onesie, with a multicolored gem pattern on it, and the puffiness around his crotch and bottom, giving away his padding. And sure enough, his rancid-smelling feet were pointed at her face, which had woken her up. Twilight caught on as to why he was there, and why he was wearing what he was.

"Spike? Celestia chose you next?" she asked him. The baby dragon giggled loudly.

"I'm a baby!" he squealed, "I'm a baby dragon!"

"Yeah, I know," Twilight said, "But did Celestia choose you to play with me?" Spike's face scrunched up as he began to grunt, giving a loud fart as he began to mess himself, a bulge forming in the back of his onesie, He giggled again.

"Me make poopy!" he squealed. Twilight raised her eyebrow, a bit frustrated that Spike wouldn't answer her. Luckily, Celestia flew in through the window, having finished raising the sun. She saw Twilight awake and smiled.

"Good morning, my sweet filly," she said, hugging her. Twilight giggled a little and hugged her back. No matter how old she was, she always loved hugging Celestia, as she found her very cuddly.

"Good morning, Mommy," she said. Celestia then looked at Spike.

"I see you've met your playmate for today," she said.

"Yeah," Twilight said, "So you decided to go with Spike?"

"Yes," Celestia said, "I know how much you love playing with your favorite assistant." Twilight giggled again.

"Mm-hmm," Twilight said, "He could play with me for ages." Celestia's smile dropped a bit.

"Well... that's actually why I chose him next," she said.

"What do you mean?" Twilight asked, looking at her pretend mother.

"See, when I talked to Spike to ask him, I asked Spike over tea to hopefully improve my chances," Celestia said, "However, he was a little more willing to accept this offer than I thought. The thought of getting to play with you was enough for him, because he was a tiny bit desperate for it."

"Desperate?" Twilight asked. Celestia nodded.

"Yes," she continued, "He told me that ever since I appointed you to Royalty, you've been busier and busier, and he doesn't get to play with you as he used to when you were a filly. The only times he gets to spend time around you is whenever you ask him to take a letter or have him help you with your booksortcations. Basically, he feels that he is no longer the baby dragon you hatched from his egg, and feels more like a Princess' servant." Twilight looked down in so much guilt and sadness. She knew Spike always asked her to play with her over and over, and she always told him "Maybe later" or "Maybe next time," but she never knew he felt so bad about it.

"Oh... oh my..." she said, "He... he said all of that...?"

"I'm afraid so, honey," Celestia said, "He really misses when you used to be more available." Twilight felt a tear come to her eye. Whenever Spike was upset, she could feel it as well.

"B-but... if... if he felt so bad... why didn't he tell me...?" she asked, her voice breaking, "...I... I would've listened to him... I'm always considerate to his feelings..."

"Well, that's what I asked him," Celestia finished up, "He explained that he felt you wouldn't listen, and that your Royal duties wouldn't let you listen. He figured that it would be telling his feelings to a brick wall, not his best friend." Twilight began to weep lightly into her hooves, feeling bad for Spike. Celestia pat her back lightly.

"I know it feels terrible, but these are his words, I assure you," she said. Twilight sniffled and hugged her diapered friend, who had been sucking his claw in boredom. She hugged him tight, ignoring the strong stench coming from his full diaper.

"I'm very sorry, Spike!" she apologized, kissing his cheek, "I'm very sorry!" Spike giggled and hugged her back.

"Twily cuddly..." he said, licking her cheek. Celestia smiled.

"Isn't that precious?" she said, patting them both on their heads. Twilight looked at Spike.

"I promise that all my attention will go to you today," she said.

"Yay!" Spike squealed as Twilight let go of him.

"But I do wonder," she said, "If he accepted your offer, then why did you regress him? I thought if they accepted, then they don't have to be regressed, like Pinkie, Applejack, and Fluttershy." Celestia smiled again.

"Well, I regressed him for you, actually," she said, "I figured you would have a better experience with Spike if he were the baby dragon you hatched years ago, so I took it upon myself to regress him for you." Twilight smiled. "Of course, if you prefer me to restore his mind to normal, I can." Twilight looked at Spike again, who was poking at his messy diaper in interest.

"No, it's fine, Mommy..." she said, "...he's perfect the way he is..." She hugged him again, making him giggle.

"Spike like huggies!" he squealed. Twilight then caught the stench of his messy diaper once again.

"Uh, Mommy?" Twilight said, "Spike's got a poo-poo diaper." Celestia poked Twilight's diaper, making her squeal a little.

"And you're a wet filly, aren't you?" she asked. Twilight giggled and nodded. Celestia picked her up with her magic and laid her on the changing table, changing her wet diaper. After getting a new diaper, Twilight hopped off the changing table.

"Thank you, Mommy," she said.

"You're welcome, Twily," Celestia said, "Now, go wash up, and meet me downstairs for breakfast." Celestia began to walk off, when Twilight saw that Spike was still in a dirty diaper.

"Mommy, what about Spike?" she asked, "He still needs a change, too."

"Well, I think you should have the honor of changing him," she said, "He is your baby dragon, is he not?" Twilight smiled and picked Spike up.

"Yes... he is..." she said, laying him on the changing table. Celestia smiled and walked downstairs, while Twilight changed Spike's diaper.

"You're one stinky dragon, Spike," he cooed at him, "You're just as stinky as you were when you were little." Spike giggled as Twilight wiped him clean. "But I couldn't care less. All I care about is giving you the time you want back." Spike squealed in joy.

"Me like Twily!" Spike said. Twilight smiled again.

"I like you too, Spike," she said. She leaned down to kiss him, but before she could, a yellow stream of liquid came from Spike's crotch and met her face. She squealed and quickly covered Spike's crotch with a baby wipe.

"Spike!" she whined, "You just peed on me!" Spike laughed hard.

"Me go pee-pee on Twily!" he squealed, kicking his feet in the air. Twilight rolled her eyes and put a new diaper on Spike.

"You think that's funny, don't you?" she asked. Spike nodded fast. "Yeah, I'm sure you do. Now I'm gonna go wash my hooves, and my face, before we go get breakfast."

Twilight walked into the bathroom and washed the urine off her face and washed her hooves. After that, she walked back into the bedroom, grabbed Spike and Smarty Pants, and walked downstairs, sitting in one of the chairs and sitting Spike in the highchair next to her. The chefs brought everyone a stack of pancakes and eggs. Blueberry pancakes for Celestia, banana ones for Twilight, and pancakes with multicolored gems for Spike. Twilight's stomach growled as she licked her lips, very satisfied with her breakfast.

"This looks so delicious!" she said, complimenting one of the chefs, who smiled at her. Spike squealed in joy, reaching for his pancakes. Twilight giggled and used her magic to slide his plate over to her.

"Calm down, Spike," she said, "I have to cut them first." He giggled again and nodded. Twilight cut Spike's pancakes into little pieces and tired a napkin around his neck, simulating a bib as Spike hummed a small tune to himself, kicking his feet as they hung out of the highchair. Twilight smiled as she watched him, as he did the same thing when he was littler. Anyway, Twilight finished cutting the pancakes and drizzled a bit of syrup on them.

"Spike~!" she cooed at him, getting a piece onto his fork and flying it around, "The dragon's trying to find his cave! But, he can't find it! Do you know where his cave is?" Spike giggled and squealed, pointing at his mouth and sticking his tongue out. Twilight giggled and aimed the fork at his mouth. "Here it is!" Spike took the fork into his mouth, sucking on it a little as Twilight pulled it out. Spike squealed in joy again as the taste was wonderful to him, Twilight giggling.

"I know, it's yummy, isn't it?" she asked him.

"Yummy pancakes!" Spike squealed, "Really yummy pancakes!" He pointed at his mouth again, wanting a second bite. Twilight giggled again and fed Spike another bite of his pancakes, feeding herself as well. Celestia smiled, watching Twilight feed the baby dragon.

"Very familiar memories have been brought back, have they not?" she asked. Twilight smiled, feeding Spike his final bite.

"Yes, they have..." Twilight said, watching Spike suck his thumb, "I never thought I'd get to take care of the baby dragon I hatched again..." She nuzzled him, making him giggle.

"Twily love me!" he said, hugging her neck, "Me love Twily!" Twilight smiled again and pulled him out of the highchair, cuddling him in her hooves.

"Of course I love you, Spike..." she said.

"Aww..." Celestia said, a small blush appearing on her face, "It has been so long since I've seen this sight..." Twilight giggled at her as Celestia finished her pancakes as well.

"Anyway," Celestia said, "It would be so nice for you to enjoy a special moment with your baby dragon. So, is there something you'd love to do with him later today?" Twilight thought for a bit.

"I'm not sure..." Twilight said, "I don't have any ideas..." She then smiled at Spike. "Do you have any ideas, Spike...?" Spike smiled wide.

"Gamies!" he squealed loudly. Celestia raised her eyebrow.

"Excuse me?" she asked.

"Gamies! Gamies!" Spike squealed. Celestia looked at Twilight.

"Do you know what he means, Twily?" she asked.

"'Gamies' is what he called video games when he was a toddler," Twilight explained, "That means he wants to go to the arcade. That was one of his favorite things to do when he was little." Spike nodded fast.

"Yeah!" he said.

"Well, I think that's a wonderful idea," Celestia said, smiling again, "Everypony loves video games, including myself, so I think some time at the arcade would be wonderful." Twilight then got a better idea as she smiled.

"Actually, instead of the arcade, why don't we go to Stenchy McSkunkin's Fun Zone this afternoon?" she asked "It's been quite some time since Spike and I have gotten to play together, and I know Spike loves that place more than the arcade." Spike's smile widened, as he knew exactly what that place was.

"Yeah!" Spike squealed in joy, "Me wanna go!" Twilight giggled, patting his back as Celestia smiled

"Then we shall go later today," she said, "But it will have to wait after court, understood?" Both nodded.

"Yes, Mommy," they said simultaneously. Celestia smiled as one of her Pegasus Royal Guards entered the room.

"Your highness, I dearly apologize for interrupting you during your morning mealtime," he said, "But your first case will begin in two minutes, and I would hate for you to be tardy." Celestia nodded and stood up.

"Understood, Sir Guard," she said to him. She then looked back at Twilight and Spike. "I'll be back soon, my children." Both nodded as Celestia followed the guard to the courtroom. Twilight smiled.

"Hey Spike, why don't we go upstairs and play with our toys?" Twilight asked, "Someone would really love to see you again." Spike smiled wide.

"Yeah!" he said happily. Twilight giggled and pulled him out of the highchair, carrying him back upstairs. Once they reached Celestia's bedchamber, Spike looked down and giggled.

"Uh oh!" he said. Twilight looked back at him.

"What's wrong?" she asked.

"I made pee-pees!" he squealed, poking his diaper, which was now yellow and puffy. Twilight smiled.

"Oh, well let me fix that," she said. She laid him on the changing table and changed his wet diaper, giggling as she taped it up.

"At least you kept all your tinkle in your diapee and not in my face this time," she joked. Spike laughed very hard, passing a loud toot as a result.

"Twily make funny!" he yelled. Twilight smiled.

"Thank you," she said, picking him up again. She placed him in the large playpen, climbing in after him. She then used her magic to grab Smarty Pants from the rug and held it in front of him.

"Hey look, Smarty Pants," Twilight said, "It's Spike! Our best friend!" Smarty Pants looked at Spike.

"Spike...?" Smarty Pants asked. Spike squealed and grabbed Smarty Pants, hugging her tight.

"Smarty Pants!" he squealed, "Smarty Pants back!" Smarty Pants squealed and hugging Spike back.

"Spikey-wikey!" she squealed, "I never thought I'd see you again! We've been apart ever since you grew up!" Spike giggled.

"I'm a baby now!" he said, "Smarty Pants play with me again?"

"Yeah!" Smarty Pants said. Twilight giggled.

"It's nice to see you two reunited," Twilight said, "And that you didn't forget each other."

"'Course not!" Spike said, "Me love Smarty Pants!" Twilight giggled again.

"Well, let's play, shall we?" Twilight asked, "What would you like to play?" Spike and Smarty Pants both smiled wide.

"Hide and seek!" they shouted simultaneously. Twilight smiled as well.

"Good idea!" Twilight said, "Let's play!"

For the next three hours, Twilight, Spike, and Smarty Pants played back-to-back games, like Hide and Seek and Charades. The trio was playing Guards and Changelings at that moment. Spike was the guard, and the sisters were the changelings. Twilight and Smarty Pants were hiding in the closet, underneath a big pile of Celestia's clothes and towels.

"He's never gonna find us, Queen Chrysalis!" Smarty Pants whispered cheerfully.

"Silence, my subject!" Twilight whispered back, "We cannot allow that guard to find us!" Spike wandered around the bedchamber, once or twice going into the bathroom to find them, but unsuccessful. Both Twilight and Smarty Pants smirked.

"You can't find us, you can't find us!" Smarty Pants teased.

Right when it seemed like Spike was gonna give up, he heard the sound of a wet pass of gas. He smirked a little as he looked toward the closet, walking over to it. Smarty Pants yelped and looked over at Twilight, who blushed a little as she began to mess herself. Spike grabbed the towel covering them, throwing it off as he squealed in joy.

"Found you!" Spike said happily.

"Twily!" Smarty Pants whined, "Your poo-poos gave us away!"

"I'm sorry, Smarty Pants..." Twilight said, "I really needed to go... and I didn't know it was gonna be so loud..." Smarty Pants sighed and hugged Twilight.

"It's OK..." she said, "It's only a game." Twilight smiled as she finished messing herself. Luckily, the sound of hoof-clops were heard in the hallway, and Celestia walked in.

"I'm back, my precious children," she said.

"Yay!" all three of them simultaneously cheered. Celestia giggled and then sniffed the air.

"Oh my," she said, "It smells to me that one of you needs a diaper change." Spike and Smarty Pants both giggled and pointed to Twilight, who blushed and raised her hoof.

"It's me," she said, "I made poopies." Celestia smiled and lifted Twilight onto the changing table.

"It's alright, Twily," Celestia said, "Thanks for telling the truth." Twilight smiled as Celestia changed her diaper.

"Thanks, Mommy," she said.

"You're very welcome, Twily," Celestia said. She then smiled. "Alright, let's get everyone dressed so we can go to Skunky's."

"Yay!" they all cheered again. Twilight and Spike got out of their onesies and went into Celestia's closet to find some public clothes. Twilight found the purple dress she loved to wear out in public, but Spike couldn't find anything for colts.

"Mommy..." Spike said, "C... can't... find nudding..." Celestia smiled.

"Aww, well let me help you, Spike," she said. She then reached behind a big dress and smiled again. "Here's your outfit." Spike looked at it. It was a plain white t-shirt, with a pair of blue overalls. Spike smiled and reached for them.

"Yeah! Me wanna wear those!" he squealed.

Celestia giggled and helped Spike get dressed, putting the shirt and overalls on him and clipping them on his shoulders. They were a little small for him, which caused his diaper to press against his crotch and backside a little, but there were still comfortable to the baby dragon. Anyway, after getting Spike dressed, she grabbed the stroller out of the closet. Twilight grabbed Smarty Pants and sat in the stroller, Spike joining her. Celestia strapped them in and pulled the sun-guard over them.

"Everyone comfy?" she asked.

"Yes, Mommy," everyone said.

"Wonderful," Celestia said, "Alright, everyone enjoy the ride."

Celestia pushed the stroller out of the Castle and pushed them to Stenchy McSkunkin's Fun Zone. The cool breeze and light bouncing of the stroller as it was pushed felt great, and Twilight rested her back against the padded seat as she smiled. But then, Spike turned a little bit to hug Twilight tight, nuzzling into her dress. Twilight jumped a little at the sudden touch, but instantly smiled.

"Me... me love you, Twily..." Spike said, nuzzling into her dress again. Twilight blushed in flattery as she hugged him back.

"I love you too, Spike..." she said, "And I promise... once we get back home... I'll make you a necessity in my life once again. No more putting my royal duties in front of my number one assistant." Spike smiled again.

"Yay!" he squealed. Twilight giggled.

"You silly baby dragon," she said, kissing his cheek.

After pushing the stroller for about ten minutes, Celestia and her foals finally reached Stenchy McSkunkin's Fun Zone. The very strong smell of pizza and cake hit their muzzles, almost making their mouths water. Several games were everywhere, an animatronic band was on the stage, upbeat music was playing, and several little fillies and colts were playing games and having fun. Twilight, Spike, and Smarty Pants all squealed in excitement, as there were itching to have fun. Celestia pushed them up to the red rope, where the foal-check manager was, dressed as a honey badger. He smiled at Celestia.

"Welcome to Stenchy McSkunkin's Fun Zone, Princess Celestia!" he said, "My name is Han E. Badger, and I'm Stenchy's cousin!" Celestia smiled.

"Good afternoon, Mr. Badger," she said, giving a royal bow at him. Han E. Badger looked at the foals in the stroller.

"Why, hello there, little cuties!" he said, "Are you here to have fun?" All giggled.

"Yeah!" they all said.

"Well you've come to the right place!" Han E. said. He grabbed his stamper and pressed it on the stamp ink a few times. "Please show me your paws, please!" Spike, Twilight, and Smarty Pants held out their hooves. Han E. stamped their hooves, and then Celestia's.

"Okie Dokie!" Han E. said, removing the rope, "All stamped up! Remember, I'm Han E. Badger, and if you need anything, come get me!" Celestia smiled.

"What do we say, everyone?" she asked the foals.

"Thank you, Mr. Badger!" they all said with smiles.

"You're very welcome, everyone!" Han E. said, "Now, go have fun!"

After Celestia unstrapped the foals, put the stroller in the storage closet, and ordered 150 tokens, she gave everyone fifty each and allowed them to play amongst themselves, while she sat at a table and kept watch. From playing skee-ball to crawling through plastic tunnels, Twilight, Spike, and Smarty Pants were simply having fun, collecting tickets, and winning big. But the best part about it to them is that they could spend time altogether with each other. After playing for an hour and a half, they joined the table with Celestia for some food, their won tickets hanging around their necks like snakes. The three foals shared a personal pineapple-hay pizza, while Celestia enjoyed a salad.

"I'm having so much fun here!" Smarty Pants squealed.

"Me too!" Spike said, marinara all over his face, "Me love this place!" Twilight giggled and wiped his face with a napkin.

"I'm having fun as well!" she said.

"Well, I'm glad everyone is enjoying themselves," Celestia said, feeding herself a bite of her salad, "I'm guessing my idea was a good one, correct?"

"Yeah!" Spike squealed. Celestia giggled.

"I'm glad you think so, Spike," she said. Right then, the music stopped, and the sound of microphone feedback was heard as everyone looked to the stage. Han E. was onstage with a microphone.

"Is everyone having fun?!" he asked. Fillies and colts cheered very loudly. "I'm glad you are! But now, it's 6:00! You know what that means!" Fillies and colts cheered again.

"Stenchy! Stenchy! Stenchy!" they chanted loudly. Han E. smiled.

"That's right, kids!" he said, "Put down the pizza and hurry up in the restroom, because now, it's time for the live show of the star of the place, and my good cousin..." He moved from the front of the curtains and introduced the star.

"Stenchy McSkunkin!" he yelled. The curtains opened and out came the mascot of the place, a giant striped skunk with huge whiskers, named Stenchy McSkunkin. Han E. gave the mic to Stenchy as Spike smiled wide.

"It Stenchy!" he squealed happily. Twilight smiled.

"I know!" she said, "And if you're lucky, you'll get to dance with him!" He squealed again as Stenchy spoke.

"Hello, kids!" he said, "It's your stinky pal, Stenchy McSkunkin! Is everyone having fun in my fun zone?!" Everyone cheered again, Spike louder than everyone. "It sure sounds like fun! But you know what? I really feel like I need to dance, but I don't wanna dance all by myself. Is there anyone out there who wants to dance with their favorite skunk?" A lot of "pick me" chants rang out as Stenchy looked out to choose a volunteer. Spike repeatedly jumped up and down on the chair with his hand raised, hoping Stenchy would pick him. Twilight crossed her hooves, rooting for him. Luckily, both of them got their wish, as Stenchy looked at Spike with a huge smile.

"Wow!" he said, "Hey everyone, look! I think I see a baby dragon back there!" Everyone turned to look at Spike. "Hey, little one, come up to the stage!" Everyone cheered for Spike loudly as he squealed in excitement, looking at Celestia for approval.

"Go ahead, Spike," Celestia said, patting him on the back. Spike squealed again and ran quickly onto the stage, getting face to face with Stenchy, who smiled at him.

"What's your name, baby dragon?" he asked.

"Spike!" Spike squealed loudly.

"Well, Spike," Stenchy said, "Would you like to dance with Stenchy?"

"Yeah!" Spike said.

"Well then!" Stenchy said, "Han! Hit the music!"

Han E. smiled and restarted the music. A very upbeat disco song began playing, and Stenchy began dancing. Spike hesitated for a bit, a little confused about what dances to do. But, he then began mimicking Stenchy's dance moves, getting cheers from the crowd. Twilight smiled, watching him dance with Stenchy as Celestia cuddled her from behind, pulling her into her lap.

"More memories returning?" Celestia asked.

"Yes..." Twilight said, "He used to dance with Stenchy every time he was in here, even if he wasn't chosen to go up there. This place used to make him so happy, and he always thanked me for taking him." Twilight sighed. "I just... I just wish I didn't make him feel the way he did to accept your offer... I wish... I could've thought about him more than myself... so he could see me as his hatcher and not a brick wall..." Celestia hugged Twilight a little tighter.

"I'm sure it still hurts you, Twily, but look at him," Celestia said, "He's happier than ever right now, and that's because of you. You were the one who suggested we come to this place, because you knew he would love it. If you ask me, this is a perfect way of thinking about him more than yourself." Twilight looked at Celestia.

"You really think so?" she asked.

"I know so," Celestia said, "Just because something pains you doesn't mean you can't fix it, and this is a nice way for you to fix it." Twilight smiled again, watching Spike dance again.

"Yeah... I suppose it is..." she said.

After Spike and Stenchy danced together to a five-minute song, Stenchy complimented Spike's dance moves, gave him a handful of tickets and a big hug, and sent him off the stage so another filly or colt could dance with him. Spike quickly ran over to Twilight and Celestia and jumped into Twilight's hooves.

"Me did it!" he squealed loudly, "Me gotta dance with Stenchy McSkunkin!"

"I know, Spike!" Twilight said happily, "I'm so happy for you!" Spike giggled.

"You're so lucky, Spike!" Smarty Pants said, "I've never got to dance with Stenchy before! It must be wonderful!"

"It is!" Spike said, "Stenchy good dancer, and he say me good dancer too!"

"You're a wonderful dancer, Spike," Twilight said, kissing his cheek, "I'm glad you had fun with Stenchy." Spike giggled and hugged Twilight tight.

"Me love you, Twily!" he said happily.

"I love you too, Spike," Twilight said. Celestia smiled and joined the hug, along with Smarty Pants.

"This is nice," she said, "We definitely are one big happy family." Spike giggled again.

After spending another two hours at Stenchy McSkunkin's Fun Zone, everyone was ready to go. First, everyone cashed in their tickets and bought prizes. Smarty Pants got a can of silly string and a noisemaker, Twilight got a yo-yo, a pair of fuzzy dice, and a poster, and Spike got a giant Stenchy plushie, about the same size as him. After getting their prizes, Celestia got them back into the stroller and went to the foal-check zone again. Han E. checked their stamps and made sure they came in together, and let them leave. Spike leaned back, cuddling his plushie as Twilight nuzzled him.

"Did you have fun, Spike?" she asked.

"Yeah!" Spike said, "Me love Stenchy!" Smarty Pants smiled.

"I know!" she said, "And look! Stenchy gets to go home with you!" Spike hugged his giant plush tighter.

"Yeah!" Spike squealed again, "Me love you Stenchy!" Twilight smiled and grabbed Stenchy with her magic, making it look like he was talking.

"I love you too, Spike!" she said, trying her best to mimick Stenchy's voice. Spike giggled and nuzzled him again. For a few minutes, it was a silent ride, Spike cuddling Stenchy and Twilight cuddling Smarty Pants. Halfway there, a foul smell filled the stroller, and Smarty Pants was the first to catch it as she sniffed the air.

"Eww!" she said, covering her muzzle and looking at Twilight, "Twily, did you make a stinky?!" Twilight shook her head.

"Nope," Twilight said, "I'm clean." Spike giggled.

"Me make poopy!" he said proudly.

"Aww, Spike!" Smarty Pants said, "Why didn't you wait until we got home first? That's really stinky!"

"Oh... sorry..." Spike said. Twilight smiled and used her magic on Stenchy again.

"I don't think you're very stinky, Spike," Stenchy said, "I think you smell kinda nice, and I'm a skunk." Spike giggled.

"Stenchy no mind it!" he said. Smarty Pants sighed and hugged Spike.

"I don't mind either, Spike," she said, "You're more cuddly than stinky." She kissed his cheek, making him smile again.

"Me love you, Smarty Pants," Spike said.

"I love you too, Spike," Smarty Pants said. That's when a loud fart came from Twilight as she messed her diaper as well with a sigh of relief. Spike and Smarty Pants giggled and held their noses.

"Twily go poo-poo too!" Spike squealed.

"Aww!" Smarty Pants whined, "You too?!" Twilight blushed and giggled.

"Sorry... I had a lot of pizza and really needed to go..." she said.

"Great..." Smarty Pants said, "Now I gotta share a stroller with two stinky babies..." Everyone giggled and rode the rest of the way in silence.

After getting back to the Castle, Celestia took the foals upstairs and placed the stroller back in the closet. She changed Spike and Twilight and gave them a bath, Smarty Pants and Stenchy joining them. After their bath, Celestia re-diapered the foals and dressed them in their night-clothes. At that point, Celestia was nursing Spike, Twilight watching him. He only needed to suckle for two minutes, as his reptilian stomach didn't need much milk to be full. He slowly pulled away from Celestia's teat and wiped his mouth.

"All better, Spike?" Celestia asked, patting his back. Spike's face twisted a bit as he let out a loud belch, then sighed.

"Me better now," he said. Celestia smiled.

"Wonderful," she said, "Alright, I think it's time for the babies to go night-night." Twilight nodded and grabbed Smarty Pants, while Spike grabbed Stenchy. Celestia used her magic to tuck both of them into the crib, gave them a kiss on their muzzles, and turned off the light.

"Goodnight, my little angels," she said.

"Goodnight, Mommy," Twilight and Spike said. Celestia laid down on her rug and went to sleep as Twilight snuggled Spike.

"I really enjoyed playing with you, Spike..." she said, "It was nice to play with you like I did when you were little..." Spike smiled.

"Me like playing with Twily..." he said, nuzzling into her pajamas, "...cuz Twily my sissy..." Twilight blushed very hard as she felt her heart skip a beat at his kind words.

"You really see me as a sissy...?" she asked.

"Mm-hmm," Spike said, "Twily fun to play with, and me love her..." Twilight kissed his cheek.

"I love you too, Spike..." she said, "Goodnight..." Spike smiled again.

"Ny-ny, Twily..." he said. Twilight and Spike fell asleep, deep in each other's embraces.

~~~~~~~~~~

Spike woke up in his bed the next morning with a loud yawn. Rubbing his eyes and smacking his lips, he sat up, feeling something heavy sitting in his lap. He opened his eyes and looked in his lap, seeing the Stenchy plush he had gotten the previous day. Spike smiled and giggled a little.

"Hmm, I wonder how this got here..." he sarcastically said, giggling again, "Man... that was an awesome time, yesterday..." Spike hugged Stenchy for a little, but then Spike noticed a scroll wedged in-between Stenchy's hind legs, wrapped in a purple and green ribbon. Spike grabbed the scroll and opened it, reading to himself.

"Dear Spike," he read, "Thank you so much for agreeing to play along with Twilight and pretending to be a foal. And I must say, you did a wonderful job pretending to be regressed. I didn't believe you could keep it up, but I'm glad you could, so you could hear her apologies." Spike smirked.

"Yeah, but it wasn't easy," Spike said, "I almost blew it like twenty times, because of how nice Twilight was being." He continued to read.

"And I hope you enjoyed your time with Twilight," he read, "Because Twilight sure did. Also, I know you accepted without a gift request, as you just wanted to spend time with Twilight, but I thought of something you've also wanted for a long time, and I took the liberty of arranging something special regarding this. However, though I trust you as I do Twilight, you must keep this to yourself, and speak of Twilight's fetish to nopony else, not even the ones who know about it. Your Princess and co-mentor, Celestia." Spike smiled, but was also a little confused.

"Well, that's great," he said, "But what is she talking about...? Arranged something special... regarding what...?" Right then, there was a knock at the door. Spike groaned and stood up, walking downstairs.

"I swear," he said, "If this is another pony asking for an autograph from Twilight, I'm gonna be mad." He went over to the door and opened it. "Look, I told you, Twilight is in Cant-"

He cut himself off when he saw who was standing at the door. It was Rarity, wearing her saddlebag and sunhat. She looked at Spike and smiled.

"Good morning, Spike," she said, doing a ladylike curtesy at him. Spike yelped.

"Rarity!" he said, "Is today a gem-hunting day?! I-I-I think I forgot again! If you give me a few minutes, I can-" Rarity placed her hoof over his mouth.

"You don't need to worry about anything, Spike," she said, "For once, I am not here to have you accompany me to the gem-grounds." Spike blinked in surprise.

"Oh..." he said, "Well... what do you need...?" She smiled and pulled a coupon out of her saddlebag.

"Well, I was on my way to that new French restaurant that recently opened to cash in this coupon," she said, "However, after reading this on my way there, I realized it was for two, and I have no one to share it with, soooo..." Spike instantly caught on.

"Are... are you... are you...?" Spike asked.

"Yes," Rarity said, "Would you like to share this coupon with me?" Spike gasped loudly.

"Are you asking me on a date?!" he yelped. Rarity giggled.

"I suppose I am," she said. Spike squealed excitedly.

"Holy cow! Yes!" he said, "I'll go!" Rarity smiled. "B-but, I just woke up! Sh-should I go upstairs and take a shower or put on something to wear or-?!" Rarity put her hoof over his mouth again.

"No, Spike," she said, nuzzling him, "You're perfect just the way you are." Spike smiled, blushing hard. "Now, let's go, darling."

Spike nodded fast and hopped onto Rarity's back, Rarity using her magic to lock the Castle back up. Spike excitedly hopped up and down on Rarity's back, as he was going on a date with the mare he's always had a crush on. Speaking of which, once he thought about it, he smiled and looked toward Canterlot.

"First a playdate with Twilight, and now a real date with Rarity?!" Spike said in his head, "This is awesome! Don't worry, Celestia! Twilight's secret is safe with me!" Rarity had just gotten to the restaurant and right before Spike went in, he smiled another time.

"Oh yeah, and thanks, Princess Celestia," he said, "Keep Twilight safe for me."

Author's Note

And I must say, you did a wonderful job pretending to be regressed. I didn't believe you could keep it up, but I'm glad you did, so you could hear her apologies.

Yes, Spike was pretending to be regressed for this chapter. See, this is a compromise. I really wanted to keep Spike normal for this chapter, since he's got a good reason for why he accepted. Seriously, I can't be the only one out there that thinks Spike is drifting further and further away from Twilight ever since she became an Alicorn. But I feared that people would begin to call me out for not regressing characters as often as I made it seem, so I made a compromise.

I'm am VERY sorry for such a long delay. I've got a job now, and I'm going into my final year of high school, so I've been much, much busier than I use to be. I hope I haven't been away for too long, and that I still have a good amount of readers for this story. I'm just glad I was finally able to continue this story.

ANYWAY! Votes are back, and new characters have been chosen!

Vinyl Scratch*
Octavia*
Princess Cadence*
Shining Armor*
Minuette
Big Macintosh
Princess Luna
(*Separately first, then together later, once I start combining characters)

Also, once the winner is selected, a new name will take its place, so new characters can always be voted for! (Some characters I will have to reject, on accounts that I can't make anything out of a character, or because I can't stand them in the show) [Please do not ask for Discord or Starlight Glimmer, because they will be rejected. Tear me apart in in the comments if you want, but I just absolutely hate them both.]

Cast your votes now, and in two weeks, the winner will be decided.

Thank you for being patient, and I hope you enjoyed Spike's chapter.

Caddie(Princess Cadence)

Twilight woke up the next morning to a rather calm voice. A very calm, cuddly voice. Her ear flicked in the direction of the voice, her eyes still closed.

"Twily... Twily..." the voice said in a light singsong sound, "...wakey wakey... it's morning..."

Twilight's lips curled into a smile as she listened to the voice. The voice made her feel so warm, cuddly, and safe. Not only was it a sweet voice, but it sounded familiar. Very familiar, as if she had heard it while a filly. But, this voice didn't sound like Smarty Pants' voice, or a friend's voice, not even Celestia's voice. This voice sounded much more familiar, as if she knew the owner of this voice earlier than Celestia.

"That voice..." she mumbled to herself, "It... it sounds... so familiar... but... but who is it...?" But then, when she smiled at the voice, it spoke again.

"Ohp! I think I see a smile!" the voice cooed. Twilight then felt a hoof run through her mane very comfortably. "Is Twily awake yet?" Right then, Twilight knew exactly who it was, as there was only one pony in her life that woke her up so calmly and pleasantly.

She very slowly opened her eyes, and sure enough, she was correct. She saw a familiar pink pony standing over her, wearing a pink bathrobe, and a bit of white peeking out around her crotch, showing off her diaper. Twilight blinked a few times, rubbing her eyes as she looked up at the pink pony.

"C... C... Cadence...?" she mumbled. The pink pony smiled and very slowly laid next to Twilight, mimicking a mother deer laying with her fawn. Sure enough, it was her. To others, this pink pony was Princess Mi Amore Cadenza, Princess of the Crystal Empire. But to Twilight, it was Cadence, her old foalsitter and her sister-in-law.

"Good morning, Twily," she said, "Are you awake now?" Twilight moved over a little and buried herself in Cadence's furry side.

"Cadence..." she mumbled, "M... Mommy... chose you next...?"

"That she did," Cadence said, very slowly removing the blanket from Twilight so she wouldn't be tempted to fall asleep again.

"And... and you're not regressed...?" Twilight asked, her sleepiness slowly fading.

"Why would I be?" Cadence asked, "I don't need to be regressed to play with my Twily!" She booped Twilight's nose, which made Twilight giggle like a baby.

"So... you're OK with this...?" Twilight asked, sitting up and resting against Cadence, "Like... seeing me in a diaper...? This doesn't make you uncomfortable...?"

"Well, it's quite surprising," Cadence said, "But of course not. Why would I be uncomfortable to see my old Twily back?" Twilight smiled, but then she felt puffiness on the back of Cadence's robe.

"Are you wearing a diaper too, Caddie?" Twilight asked, using Cadence's nickname, that she only used when alone with her. Cadence giggled.

"I might be," she said, letting Twilight poke her diaper a second time. Twilight pieced it together.

"Oh my..." she mumbled, "Caddie... are you my playmate for today...?" Cadence giggled.

"That's right," Cadence said, "I took care of you for most of your life as the guardian, but for tonight, we're equals." Twilight was extremely happy inside.

"But... that means you have to act like a foal and wear diapers..." Twilight said, "And... you're OK with this?"

"Of course I'm OK with it, Twily," Cadence said, nuzzling her, "Besides, ever since I had Flurry, I've been in desperate need of relaxation and leisure. So, I figured a few hours of foal-play would be a nice way to recharge my batteries." Twilight smiled.

"It sure is!" Twilight said, "Acting like a foal is so relaxing, because you can be completely carefree and happy. I love it so much!" Cadence giggled.

"From the looks of things, I'd say so," Cadence said. Twilight blinked twice.

"But Caddie," she said, "That means Shining Armor is alone with Flurry, and he also has his responsibilities as well. Don't you think that's a bit too much to handle for him?"

"Yes, I realized that a few minutes after I accepted Auntie Celestia's offer," Cadence said, "But I promised him that after he finishes his Royal Guard duties tomorrow, I'll have a nice hot bath and a soothing massage for him." Cadence giggled. "And maybe something else, that I prefer not to mention openly." Twilight giggled as well.

"Don't worry, you don't need to," Twilight said, "Anyway, you said you're OK with foal-play, right?"

"Yes?" Cadence said.

"Well... um... how can you prove it...?" Twilight asked, "...I just want to be absolutely sure..."

What happened next was something Twilight wasn't expecting. Cadence smiled and raised herself from laying on her stomach to sitting. She then raised herself a little bit, arched her tail a bit, then sighed. A loud hissing noise was heard by Twilight, and she could see Cadence's white diaper very slowly become yellow. Her eyes went big as Cadence sighed in pleasure, the hissing noise fading and Cadence's tail went limp again.

"C-Caddie..." Twilight said, "Did... did you just...?" Cadence giggled.

"As I said, I'm OK with it," she said, sitting down again. The wet diaper pressed against her backside, and Twilight noticed that Cadence didn't make any cringing faces or signs of discomfort after sitting in her own urine. Twilight blushed, staring at Cadence's now-wet diaper. Never once in her life had Twilight even been in the bathroom at the same time Cadence was using the toilet, but now she had seen her wet a diaper. "Do you believe me now, Twily?"

"Yes, Caddie..." Twilight said, "I believe you..." Twily hugged her sister-in-law, then looked up.

"Um, where's Mommy?" Twilight asked, "She's usually here by now."

"Well actually, Auntie Celestia is going to spend the day alone to catch up on her responsibilities as a Princess," Cadence said, "So, it'll just be you and me for today." Twilight looked down.

"Oh..." she said. Cadence saw the disappointed look in Twilight's face and smiled.

"I know that'll be a bit unusual than what you're used to," Cadence said, "But I see this as our makeup for the last time we tried to spend time together."

"Oh?" Twilight asked, looking up at her.

"If you recall, our last time together was tarnished by Discord," Cadence said, "So, now we can make that up today, just you and I." Cadence kissed Twilight's cheek, making her blush.

"I... I never thought about it that way..." Twilight said, "That sounds wonderful..."

"Of course it does, Twily," Cadence said, "And we can do whatever you want today." Twilight smiled and hugged her again, Cadence hugging her back. After hugging for a few seconds, Cadence nuzzled Twilight.

"So, why don't we go get some breakfast?" she suggested. Twilight smiled.

"That sounds great," Twilight said, "But, are you going to change yourself first?" Caddie smiled and laid on her back, her wet diaper facing Twilight.

"Actually, would you like to change me, Twily?" she asked. Twilight blushed extremely hard.

"Oh... oh my..." Twilight said, "C-Caddie... are... are you sure...? You don't... need to embarrass yourself for me..."

"Who said this was embarrassing, hmm?" Cadence asked, "I'm just asking my sister-in-law if she'd like to change me, nothing more. Of course, it's a question, not an order, so you don't have to." Twilight blushed a bit harder and nodded.

"Sure," she said, "I'll change you." Cadence smiled.

"Well, go ahead," she said, "Take your time."

Twilight grabbed a spare diaper and supplies. After that, she changed Cadence's wet padding. Twilight's emotions fought each other inside her mind as she did. She was changing the mare who used to foal-sit her, which made her feel strange, but she also felt happy, flattered even. She never knew Cadence was willing to stoop to such a level to make her happy.

"I'm done," Twilight said. Cadence smiled and sat up, using her magic to discard her wet diaper.

"Thank you, Twily," she said, kissing her cheek. Twilight blushed again and giggled.

"That was... strangely enjoyable," she mumbled.

"Oh was it?" Cadence asked.

"Yes," Twilight said, "I'm a bit embarrassed to admit it... but it was." Cadence smiled.

"Well, I'm pretty sure that's not the only time I'll need a new diaper," Cadence said.

"R-really?" Twilight asked.

"Of course," Cadence said, "I'm not holding anything back, Twily. Auntie Celestia wanted you to have a babyish playmate, so that's what I'm going to be for you, no matter what." Twilight's weird feelings soon became flattery.

"You mean it, Caddie?" she asked.

"Of course I mean it, Twily," Cadence said, "My only veto is crying, on account that I can use my voice." Twilight giggled.

"Deal," Twilight said, "Plus, I'm pretty sure Flurry bombards you enough with the crying, so I wouldn't expect you to cry for something." Cadence and Twilight shared a laugh, then Twilight's stomach growled. Cadence smiled.

"I think it's about time we go get breakfast, wouldn't you say?" she asked. Twilight smiled and stood up, but before she could begin walking, Cadence's magic engulfed her and placed her on Cadence's back. Twilight jumped at the sudden magic pull, but blushed when she saw where she landed.

"I figured you'd like a ride downstairs," Cadence said, "After all, this was your favorite thing to do when you were little."

Twilight remained silent as she was too happy to speak. Cadence walked downstairs to the dining room, her wings extended to keep Twilight from falling. The gentle bouncing motion felt great as Twilight rode on her sister-in-law's back. It had been several years since she had rode on the back of another pony, and she had forgotten how it felt. But now, the feeling had returned, and she was loving it as a sigh of relief escaped her mouth. Cadence's ear flicked as she caught the sigh and giggled a little bit.

"Do you like that, Twily?" she asked.

"Yes... I really do..." Twilight said, "It feels wonderful... now I know why Spike loves this so much..." Cadence giggled again.

"Well, I knew you'd like it," Cadence said, "I know what's right for my sweet sister-in-law." Twilight blushed again.

"Caddie~" she whined, "How many more times are you gonna make me blush today?"

"As many times as I must," Cadence said, "You're just as sweet and precious as you were as a filly." Twilight giggled.

"Thanks, Caddie," she said, nuzzling the back of her neck.

A few seconds later, Cadence and Twilight had reached the dining room. Cadence let Twilight off of her back and sat in one of the chairs. Twilight was about to sit in a different chair, but instead, she decided to sit in Cadence's lap. Cadence smiled a little bit.

"Well, this is a bit unexpected," Cadence said.

"I... I kinda wanna sit with you," Twilight said, "If... if you don't mind, though. I could go sit somewhere else..."

"Of course I don't mind, Twily," she said, petting her mane, "Why would I be uncomfortable with my sister-in-law sitting with me?"

"I suppose it's impossible," she said. Cadence smiled as the cooks brought out their breakfast. Twilight's eyes went big as she saw what was brought out. It was cinnamon French toast, with sunny-side-up eggs, a bit of cut melon, and apple juice. Cadence smirked.

"Does this breakfast look familiar to you?" she asked.

"This... this is my favorite breakfast as a filly..." Twilight said, "My mom used to always make this for me..."

"That she did," Cadence said, "So, I spoke to the cooks, and they were happy to make it for you." Cadence grabbed a fork and knife with her magic and cut the toast up into small squares. Right then, Twilight realized she had forgotten something.

"Caddie wait," she said, "I can't eat without Smarty Pants. She could want some." Cadence smiled.

"Oh my," she said, "Well, give me a second." Cadence pointed her horn toward Celestia's bedchamber and used her magic to grab Smarty Pants and bring her downstairs. Twilight smiled and grabbed her best friend out of the air.

"Smarty Pants!" she said, kissing her cheek, "Sorry for leaving you up there."

"It's OK, Twily," Smarty Pants said, "You still remembered me." She looked up at Cadence and smiled wide. "Caddie!" She hugged Cadence. "I haven't seen you in a long time!"

"I haven't seen you in quite sometime either," Cadence said, "I'd never forget Twily's favorite toy when she was little." Smarty Pants giggled as Cadence finished cutting Twilight's breakfast, poured some syrup on her toast, and got some on her fork.

"Here comes the train, Twily!" she cooed, "Open up the tunnel!" Twilight smiled and opened her mouth as Cadence fed Twilight the bite of toast. "How is it?" Twilight smiled wide as she swallowed.

"It tastes amazing!" she said, "It tastes just as I remember it!" Cadence giggled and fed her a second bite.

"I knew you'd like it," she said. After a bit of silent eating, Twilight spoke again.

"So, how do you plan to spend our time together?" she asked, licking syrup from her face.

"Well, I was about to ask you the same thing," Cadence said.

"Oh?" Twilight asked.

"Of course," Cadence said, "After all, you're the younger baby here, so I think you should have a say in what we do today." Twilight received another bite of her breakfast and thought for a second.

"Hmm..." she mumbled, "I uh... I don't know.. Mommy usually suggests things to do while we do this..."

"Well," Cadence said, wiping Twilight's mouth, "Why don't you think of things we like to do together?"

"Like go to the Starswirl Museum?" Twilight asked.

"Ehh, think of our earlier years," she said.

"Go to the spa?" Twilight asked.

"A little earlier," Cadence said.

"Go to the park?" Twilight asked. Cadence smirked.

"Just a tiny bit later," she said. Twilight thought for a bit, then her eyes went huge.

"Are you suggesting 'that'...?" she asked.

"Suggesting what, hmm?" Cadence teased.

"You wanna go to the carnival?" Twilight asked.

"I don't know, do you?" Cadence asked. Twilight squealed in joy.

"Oh yes!" she excitedly squealed, "It's been a long time since I've gone there and to go with you again will only make it more fun!" Cadence giggled as she fed Twilight the last bite of her breakfast.

"Well then, we'll go to the carnival later tonight," Cadence said, "It's more fun when you go when its dark outside."

"I know!" Twilight squealed, "I haven't been there since Spike was a hatchling, so it'll be wonderful to go again." Cadence smiled.

"I'm glad you think so," she said, "But how about we play a game to burn some time?"

"Like what?" Twilight asked.

"Well, I would love a game of hide and seek," Cadence said, "How about you?"

"That sounds like fun!" Twilight said, "Can I hide first?"

"Oh course you can, Twily," Cadence said, "But, we need to get ready first."

In a matter of five minutes, Twilight and Cadence wrapped their horns in tinfoil and tied a rope around their torsos, which pinned their wings to their sides. This kept them from flying and using their magic to hide, which they felt was cheating.

"Alright," Cadence said, "You've got twenty seconds to hide, Twily!"

Twilight squealed and grabbed Smarty Pants, running off to hide as Cadence began counting to twenty. Twilight avoided hiding in the courtroom, as cases were still going on and she didn't want to bother Celestia. She also avoided hiding in any bathrooms, as that was too easy. Right after she heard Cadence get to fifteen, she quickly ran into the Royal Guard armor storage room and hid, uncomfortably laying on a bunch of helmets. She knew she had hid in much more uncomfortable places, so she didn't worry too much.

She remained quiet for a solid three minutes, listening to Cadence's hooves clop as she walked around the Castle, trying to find Twilight. Twilight couldn't see under the door, and the storage room had no light, so all she could do was listen.

Soon, the door opened, and in walked someone. Twilight held her breath and tried to remain as still as she could.

"Twily~~" Cadence called, "Come out, come out, wherever you are." Twilight pressed her hooves against her mouth, trying not to giggle and expose herself. Cadence walked around, trying to find Twilight, and Twilight curled into a ball, hoping Cadence wouldn't find her. But, Cadence walked closer to her, and Twilight was about to accept defeat, but surprisingly, Cadence walked out of the storage room and closed the door back. Twilight squealed to herself happily.

"She walked off!" Twilight said, "I think I just won!" Twilight stood up and decided to sneak out and find a new hiding spot. She quietly cracked the door open and peeked out. When she didn't see Cadence, she smiled and opened the door more to get out.

"BOO!" Cadence popped out of nowhere and spooked Twilight. Twilight squealed and jumped back, tripping over one of the helmets and falling onto her padded butt. Cadence laughed hard as Twilight tried to recover from her spook attack.

"Found ya!" she squealed. Twilight sighed and stood up, grabbing Smarty Pants.

"You scared me..." Twilight said.

"Yeah, I did," Cadence said, "I just wanted to surprise you. Sorry if I scared you too hard."

"It's fine, Cadence..." Twilight said, "But... uh... now I need a diaper change..." A foul smell reached Cadence's muzzle.

"Oh my," Cadence said, "It seems I frightened the mess out of you." Cadence took Twilight upstairs to change her diaper. One change later, Cadence disposed of Twilight's messy diaper and Twilight sat up, hugging Smarty Pants again.

"Thank you, Cadence," she said.

"You're welcome, Twily," Cadence said, "Alright, it's my turn to hide. Ready?" Twilight smiled.

"Yep!" she squealed.

Twilight covered her eyes and counted to twenty as Cadence quickly hid from her. But, instead of going downstairs, she instead hid behind Celestia's sofa, a few feet away from Twilight.

"Ready or not, here I come!" Twilight squealed, taking Smarty Pants with her as she walked downstairs to find Cadence, who giggled quietly to herself as she watched Twilight leave the room.

Twilight checked every room downstairs to try and find Cadence, but had no luck. She checked the kitchen, the dining room, the lobby, the foyer, and every single bathroom, but had no luck.

"Wow, Caddie is hiding good..." Twilight mumbled to herself.

"Need help finding her, Twily?" Smarty Pants asked.

"I don't know, Smarty Pants." Twilight said, "I've been searching for seven minutes. I've checked every single room down here, and she's nowhere to be found."

"Well, why don't you check Mommy's room?" Smarty Pants suggested.

"Smarty Pants, Caddie can't be in Mommy's room," Twilight said, "I counted in there, so it would be too easy."

"You could always try, Twily," Smarty Pants said, "Ponies always hide in weird places when playing hide and seek."

"I... I guess you're right, Smarty Pants," Twilight said, "Let's go check Mommy's room."

Twilight walked back upstairs to Celestia's bedchamber. Cadence held her breath after hearing Twilight come in as Twilight searched around the room.

"Where do you think she could be, Smarty Pants?" Twilight asked.

"Ummm... check the closet," Smarty Pants said. Twilight walked over to the closet and searched around Celestia's formal clothes, no luck finding Cadence.

"She's not here," Twilight said, Cadence shaking lightly as she kept herself from laughing.

"OK... um... how about the bathroom?" Smarty Pants suggested. Twilight shrugged and checked the bathroom. Cadence wasn't hiding in the shower, or the towel closet, or inside the medicine cabinet, or inside the toilet.

"She's not here either," Twilight said, "Do you really think Caddie's hiding up here?" Cadence's face turned red as she kept trying not to laugh.

"Of course she is," Smarty Pants said, "How about we check the balcony?"

"OK," Twilight said, "But if she's not out there, then I'm gonna go look somewhere else." Twilight went out to the balcony to look for Cadence. But, the only thing out on the balcony was Celestia's telescope and the beautiful sight of Canterlot.

"She's not here, Smarty Pants," Twilight said, walking back into the bedroom.

"Huh..." Smarty Pants said, "Maybe she's in Princess Luna's bedchamber?" Cadence strained to keep herself from laughing, but her straining only caused her to accidentally pass a loud blast of gas. She gasped as Twilight heard the sound of Cadence's "slip."

"Huh?" Twilight asked, looking toward the sofa, "Smarty Pants, did you hear that?"

"It sounded like a fart," Smarty Pants said, "Was that you?"

"No, but I think I know who it was!" Twilight squealed. She ran over to the couch and looked behind it, finally finding Cadence after ten minutes of searching.

"Found you, Caddie!" she squealed. Cadence giggled and stood up.

"Took you long enough, Twily!" she teased, booping her nose, which made Twilight giggle.

"You were hiding really good!" Twilight said, "I probably wouldn't have been able to find you if you hadn't have farted." Cadence giggled.

"Well, that was an accident," she said, "I tried to keep myself from laughing, and that happened."

"Oh, it's OK, Caddie," Twilight said, "Yours aren't that stinky. Nopony's are as stinky as Mommy's. Ask Smarty Pants."

"Eww!" Smarty Pants whined, "Don't remind me! It was hard to breath in it, and I don't even have lungs!" Cadence laughed.

"Oh, trust me, I know," Cadence said, "Auntie Celestia always ripped some pretty huge ones while we played outside or after she read me a bedtime story and thought I had fallen asleep. I sometimes had to use half a can of air-freshener to battle her clouds of death." Twilight laughed as well.

"But I did excuse myself, did I not?" a voice called. Cadence and Twilight both looked toward the door. Celestia had walked into the room, having just finished court, and having heard their whole conversation.

"Oh... sorry, Auntie Celestia," Cadence apologized, "We didn't know you were here."

"All's forgiven, Cadence," Celestia said, hugging her niece, "It was just a joke, and I'm able to take one." Twilight smiled and hugged Celestia's leg.

"Hi, Mommy," she said.

"Good afternoon, my sweet daughter," Celestia said, kissing the top of Twilight's head, "I'm guessing my next decision was a good one?"

"You bet!" Twilight said, "Caddie and I are having so much fun, and we've just gotten started!"

"Well, I'm glad to hear that," Celestia said, "Your happiness always brightens my day." Twilight blushed.

"Mommy~!" she whined, "Don't make me blush in front of Caddie!" Cadence giggled a little.

"I can't help it, honey," Celestia said, ruffling Twilight's mane with her hoof, "I just love you so much." Twilight smiled and nuzzled Celestia's leg.

"I love you too," she said. Celestia smiled and walked over to her carpet to finish some of her paperwork.

"Hey, Twily," Cadence said, "Let's continue our fun-time downstairs so we don't disturb Auntie Celestia." Twilight nodded and grabbed Smarty Pants again.

"Sounds good," she said. Cadence smiled and carried Twilight back downstairs.

~~~~~~~~~~

Once Luna's beautiful moon came out, Twilight and Cadence began getting ready to go to the carnival. Twilight got dressed into her favorite purple dress and brushed Smarty Pants' tail with her little toy brush as Cadence finished brushing her own mane.

"I'm so excited to go to the carnival with you!" Twilight said, "It's been such a long time!" Cadence giggled.

"Indeed it has," Cadence said, "I hope you enjoy your time."

"I will!" Twilight said, "How could I not?!" Cadence giggled again and put down her manebrush.

"Glad to hear you have such great spirit," Cadence said, "Alright, are you ready to go?"

"Mm-hmm!" Twilight said happily. Cadence smiled and looked at Smarty Pants.

"Smarty Pants, are you ready?" she asked.

"I sure am!" Smarty Pants said, hugging Cadence's leg.

"Well then, let's go," Cadence said.

Cadence performed a small squat and Twilight hopped onto her back, holding Smarty Pants in her hooves. Cadence then, after letting Celestia know they were about to leave, she took off and flew to the carnival. The second Twilight could see the insanely bright lights to the carnival, she squealed and began bouncing up and down eagerly. Cadence touched down at the line to the entrance as they waited in line for their tickets.

"I can't explain how excited I am!" Smarty Pants said.

"I know!" Twilight said, "And looking in from here, it's not very crowded tonight! Maybe lines won't be too long!" Cadence giggled and reached the ticket booth.

"Good afternoon, Princess Cadence," the ticketmaster said, "Princess Twilight. How may I help you?"

"Good afternoon to you as well," Cadence said, "Could we have fifty tickets please?"

"Oh, that won't be necessary," the ticketmaster said, "For royals, we simply give you these." He grabbed two pink, paper necklaces and placed them on the counter. "These will grant you unlimited rides for as long as you're here." Twilight's eyes went huge in surprise.

"Oh my," Cadence said, "Sir, I don't think I could accept this. We're here just for fun, not to conduct business."

"Oh, but I gravely insist, Princess Cadence," the ticketmaster said, "Besides, just to have you and Princess Twilight here is an honor of itself. I couldn't possibly charge you for tickets." Cadence thought for a bit, then smiled.

"Well, I humbly thank you, Sir," she said, taking the necklaces.

"You're very welcome, your highness," he said, "Enjoy your rides." Cadence smiled as a security pony let her go through the gate and into the carnival.

"Well, wasn't that mighty kind of him?" Twilight asked, "Now we don't have to worry about running out of tickets!" Cadence smiled and clipped her necklace around her neck, clipping her own afterwards.

"Yes," Cadence said, "Now, just to be fair, I think we should take turns going to rides. That way, everyone gets to ride what they want to."

"Everyone?" Smarty Pants asked, "Even me?" Cadence smiled.

"Yes, even you, Smarty Pants," she said.

"Then yeah!" Smarty Pants squealed, "Let's do that!" Cadence looked at Twilight for approval.

"I agree," Twilight said, "That's sounds fair enough to me."

"Yay!" Smarty Pants squealed happily.

"Well then," Cadence said, "Who would like to pick first?" Twilight smiled and looked at Smarty Pants.

"Smarty Pants," Twilight said, "Why don't you choose the first ride, hmm?" Smarty Pants squealed happily.

"Teacups!" she squealed, "I wanna ride the teacups!" Cadence smiled.

"Alright then," she said, "Let's go."

For the next two hours, Cadence, Twilight, and Smarty Pants all took turns riding the assorted rides at the carnival. First they started with the teacups, then Cadence chose the bumperships, and Twilight chose the Ferris wheel. After each of them chose two more rides, they all took a breath from rides and got some snacks. Cadence got some popcorn and Twilight and Smarty Pants shared some cotton candy.

"This is so fun!" Twilight said, "I've never had so much fun at the carnival before!" Cadence giggled.

"I'm glad you're enjoying yourself, Twily," she said. Smarty Pants took a huge bite of cotton candy from the stick.

"I love cotton candy so much!!" she squealed, licking her paws.

"Hey!" Twilight whined, "Save some for me, you little hog!" Cadence giggled and sighed.

"I think we should be getting back to the castle soon," Cadence said, "We've been here two hours, and I don't want to make you stay up too late." Twilight nodded.

"Yeah, sounds good," Twilight said, "But, how about one more ride?"

"Yeah!" Smarty Pants squealed.

"Alright then," Cadence said, "What ride would you like to finish off on?" Twilight and Smarty Pants looked at each other, then smirked.

"Leap of Faith!" they said simultaneously. They both pointed to a very large roller coaster a few meters away from them. Cadence looked at it.

"Oh my," she said, "That's quite a roller coaster. Are you sure you're not too afraid?"

"Heck no!" Twilight said, "I've been wanting to ride that roller coaster for years, but I've never been tall enough to ride it! I wanna ride it now!" Cadence smiled.

"Alright then," she said. Twilight smiled wide and grabbed Smarty Pants.

"Leap of Faith, here I come!"

Twilight grabbed Smarty Pants and flew as fast as she could over to the Leap of Faith, Cadence following behind her. They waited in line for about five minutes before being second in line. Twilight looked up at the massive roller coaster.

"Wow..." she said, "That's really tall..."

"Indeed it is," Cadence said, "Are you sure you still want to ride this?"

"Yes," Twilight said, "I've been waiting for years, and I may not get a chance like this with you ever again." Cadence smiled and nuzzled her.

"You've always been a brave filly," she said, "And I'm proud of you." Twilight blushed.

"Caddie, please don't make me blush now..." she said, "You're gonna mess up my scared face when they take photos..." Cadence giggled as they reached the front of the line. Twilight, Cadence, and Smarty Pants all sat in the very front car and strapped their safety belts, pulling the safety bar over their laps, which also pinned Smarty Pants to Twilight's lap so she couldn't fly off during the ride.

"We're in the front," Smarty Pants said, "That means we'll be able to see everything!" Twilight took a breath, petting Smarty Pants.

"Yeah..." she said, light fear kicking in. Cadence looked at Twilight.

"Is everything OK, Twily?" she asked.

"I'm OK, Caddie, I promise," Twilight said, "I'm just bracing myself." Cadence smiled and kissed Twilight's cheek.

"Kiss for good luck," she said. Twilight smiled and kissed Cadence back.

"One for you as well," she said. After sitting for a few seconds, the operator of the ride smiled.

"Everyone seems to be strapped in and safe," she said, "Ride will begin in three, two, one! May faith be on your side!"

She hit the button and slowly, the roller coaster began moving forward, and then up a huge incline. Twilight's fear, after Cadence's kiss of luck, had turned into eagerness as she bounced happily on the seat.

"This is happening! This is happening!" she squealed.

"I hope you don't wet yourself, Twily!" Smarty Pants teased.

"If I do, you can't blame me!" Twilight squealed. Cadence giggled as they reached the top of the incline.

"Caddie, let's count it down!" she squealed.

"Alright then!" Cadence squealed in excitement. They both took a deep breath and counted.

"Five! Four! Three! Two! One!!!"

Immediately, the roller coaster took off, going from 0mph to 70mph in less than five seconds. Twilight screamed loudly as the roller coaster rode over huge inclines and loops.

"ITTT'SSS SSSOO FAAAAAST!!!!" Cadence screamed.

"BUUTTT ITTT'SSS SOOOO FUUUNNN!" Twilight screamed in joy. Smarty Pants was unable to speak, as she was too consumed by excitement to speak. The ride ended after a full minute and came to a screeching halt at the entrance. The safety belts and safety bar automatically let up.

"Looks like you all survived!" the operator said, "Have a great night!"

Cadence, Twilight, and Smarty Pants all got off the ride and walked through the exit, all of them shivering from the excitement and their manes frazzled as all heck.

"Th-that... was AMAZING!!!" Twilight screamed, "That was definitely worth the long wait!!!"

"I'll say!!" Cadence squealed, "I've never rode on such a roller coaster, and I'm glad I just did!" Smarty Pants mumbled incoherently, clenching Twilight's leg hard. Twilight giggled.

"Looks like Smarty Pants couldn't take the speed!" she teased. Cadence giggled as well.

"Yes," she said, "But... you kinda lost it back there."

"Lost it?" Twilight asked, "Lost it how?" Cadence smirked and poked the back of Twilight's diaper. When she felt the familiar squish and smelt the familiar odor she knows very well. She blushed hard.

"I did that during the ride...?" she asked.

"You did," Cadence said, "A little bit after we hit the second loop as a matter of fact." Twilight giggled a little bit.

"I guess I can say that the Leap of Faith really scared the crap outta me!" she said. Cadence and Twilight shared a laugh, then sighed.

"Alright, Twily," Cadence said, "Let's get you back home and into a fresh diaper. It's almost midnight, and I don't wanna make you stay up too late." Twilight nodded and hopped on Cadence's back again.

"Sounds good," she said. Cadence smiled and took off, flying back to Canterlot. Once they got back to the Castle, Cadence laid Twilight on the changing table and changed her diaper.

"So, did you have fun, Twily?" Cadence asked.

"I sure did!" Twilight said, "You're more fun as a playmate than you are as a foalsitter!" Cadence smiled and powdered Twilight's bottom.

"I'm glad you think so," she said, "It definitely was fun to play with my little Twily again." She booped Twilight's nose, making her giggle like a foal.

"Oh, stop it, you!" she whined. Cadence smiled and taped up Twilight's new diaper, putting her onesie on her. Twilight sighed in comfort.

"It always feels great to get a new diaper," she said, "No matter what." She sniffed the air. "Wow, I really made quite a stinky, didn't I?" Cadence blushed and looked down.

"I... I don't think that's your mess you're smelling," she said.

"It's not?" Twilight asked, "Then what is it?" Cadence smirked.

"It's probably mine," she said. She turned her rear end toward Twilight, her diaper sagging and turning brown. Twilight blinked in surprise.

"Caddie... you pooped yourself...?" she asked, totally surprised. Cadence giggled.

"Well~ I did say earlier wasn't going to be the only time I'd need a new diaper," she said, "And those snacks from the carnival made me have to go." Twilight blushed.

"Well... I didn't say that was bad," Twilight said, "It just surprised me..." Cadence giggled as Twilight climbed off the table. "Do you want me to change you?" Cadence smiled and climbed into the table.

"If you don't mind, I'd love that," she said. Twilight smiled and changed Cadence's diaper, tossing both their messy diapers in the wastebasket. Cadence hopped off the changing table and stretched her hind leg.

"Thank you, Twily," she said, "I feel much better now." Twilight smiled and yawned.

"That's great... Caddie..." she said, fluttering her eyes. Cadence smiled again, looking down at her sleepy sister-in-law.

"I think it's time for you to get some sleep, Twily," she said. Twilight looked down and hugged Cadence's leg.

"Do I really have to...?" she asked, "I really had fun with you... and if I go to sleep... you won't be here when I wake up..." Cadence nuzzled Twilight.

"You're right," Cadence said, "I wish I could stay here with you forever, but I have responsibilities of a royal just like you do. On top of that, I'm sure Shining is wearing himself out right now, so I eventually have to go help him."

"Yeah yeah..." Twilight said, sighing in disappointment. Cadence smiled and hugged her sister-in-law.

"But, that doesn't mean we'll never get another time like this," she said, "Now that I know about your little secret, that means we can do this whenever you want next time."

"Really?" Twilight asked, "You'd do this again...?"

"Twily, I'd do anything you love to do," Cadence said, "I did everything you loved to do when I was foalsitting you, and I will still do it as your sister-in-law." Twilight smiled and hugged Cadence again.

"Thank you, Caddie," she said.

Cadence smiled and carried Twilight over to her crib, placing her inside and tucking her in. She then placed Smarty Pants in the crib with Twilight and tucked her in as well.

"Caddie..." Twilight said, speaking through her sleepiness, "...could you wait until I fall asleep... before you go...?" Cadence smiled and nodded, petting her mane.

"Of course," she said, "Goodnight, Twily."

"Goodnight... Caddie..." Twilight mumbled, her eyes slowly closing.

~~~~~~~~~~

After Twilight fell asleep, Cadence went back home to the Crystal Empire and went to sleep for as long as she could. At 7:00 A.M., she woke up once again and yawned, next to her sleeping hubby. She smiled and kissed his cheek affectionately.

"Thank you, honey..." she whispered into his ear. When a loud snore came from him in response, she giggled and sighed, rolling onto her back. That's when she caught the sight of a scroll, wrapped in a pink ribbon, sitting on her nightstand. Cadence grabbed it and opened it, reading it in her head.

"Dear Cadence," she read, "Thank you so much for agreeing to pretend to be a foal and playing along with Twilight. I don't think I've ever seen Twilight so happy with a playmate. You did quite a job, and I thank you for that. Now, I understand you asked for no reward, but I had to insist, and have rewarded you with something you could definitely use. Once again, I thank you, Cadence. Your aunt, Celestia." After reading, Cadence looked a bit confused.

"It's no problem, Auntie Celestia," she said, "But I'm confused... what reward do you mean...?" That's when Flurry began crying loudly a few feet away from her. She groaned and got out of bed, going over to Flurry's crib.

"Shh, it's OK sweetie," she said, "Mommy's here." That's when she felt that Flurry was crying because she had wet herself. Cadence smiled and changed Flurry's diaper.

"There we go," she said, giving her diaper a playful pat, "Who's my clean little filly?" She blew raspberries on Flurry's tummy, making her squeal happily and squirm. After a few seconds, she grabbed Flurry and sat on her bed with her, rocking her back and forth.

"Mommy loves you, Flurry," she said. Flurry smiled and grabbed her mother's hoof, sighing as she hugged it. Right then, to Cadence's complete surprise, she heard Flurry say something.

"M... Mo... mmy..." Flurry softly said. Cadence's ear flicked in surprise as her eyes went wide.

"...Flurry... did you... just say 'Mommy...?'" she asked.

"Mom-my..." Flurry repeated, nuzzling into her coat. Cadence's look of disbelief turned into a look of joy.

"Oh my goodness! Flurry! You just said your first word!" she squealed, "My daughter just said 'Mommy!'" Shining yawned and slowly woke up.

"Hon... is something wrong...?" he asked her.

"Flurry just said 'Mommy!'" she squealed. Shining immediately sat up.

"What?!" he said.

"Yes! I mean it!" Cadence squealed, "Flurry, can you say it again? Say 'Mommy.'"

"Mom-my..." Flurry said again. Shining gasped.

"My goodness! That's her first word!" Shining squealed.

"I know!" Cadence squealed, "Shiny, go get the camcorder! We need to save this moment!" Shining nodded and jumped out of bed.

"I gotta tell Mom and Dad and everyone!" Shining said, running downstairs to the lobby to get the camcorder, wobbling as his hind legs were asleep, "This is amazing!" Cadence giggled as she watched him leave, then kissed Flurry's cheek. She then smiled and looked out the window.

"I suppose you're responsible for this, Auntie Celestia," Cadence said, "Well, thank you very much. Anytime you want me to do that again, you can count on me."

Author's Note

OK! So let me address the elephant in the room.

Yes, I understand the waits for these chapters are extremely long, and I'm sorry for that. But, I'm 18 now, so that means I have much more responsibilities in my life now. I'm going through my final year of high school, I've got a job, and the time I have to write gets lower and lower. I'm sorry for the very long waits, and I hope I still have some readers for this story.

Anyway, Princess Cadence's chapter has come and gone. And now, voting is back up. Here are the remaining characters:

Vinyl Scratch*
Octavia*
Shining Armor
Minuette
Big Macintosh
Princess Luna
(*Separately first, then together after I start combining characters)

And now, here's what I'd like. Go ahead and vote for who you want next, AND vote for who should replace Cadence in the poll. Also, after you vote, tell me if you want him/her regressed or not. Think of this as my way of making it up to you for the long waits.

Start voting now! Winner will be selected in two weeks.

(Also, yes, I had Cadence be Celestia's niece. See, if Blueblood is Celestia's nephew, then he has to be Luna's child. And I've seen people make Blueblood Cadence's brother on multiple occasions. So, that's why I believe Cadence is Celestia's niece and Luna's child.)

[And as for Cadence's reward, if you're wondering how Celestia did that, I figured Celestia could've enhanced Flurry's thinking power a little to have her comprehend how to pronounce "Mommy." I had trouble finding out a gift for Cadence, because it's hard to give a gift to someone who probably already has everything, like a royal.]

Busted!

Princess Twilight Sparkle had just finished dinner and made her way up to her old bedchamber in Canterlot Royal Castle. She was staying the weekend in Canterlot along with her mentor, Princess Celestia, getting some friendly advice about how to handle being a royal. One of the things Twilight loved to do was spending time with Celestia. She didn't get to do that at the Grand Galloping Gala, so she was making up for it that night, for the whole weekend, even though she only had to for a day. Twilight ate up every second she got along with Celestia, no matter how long. Anyway, Twilight walked upstairs to her old bedchamber she had when she was a filly living in the Castle, one of the Pegasus Royal Guards following her. Once she got there, she turned to face the guard.

"Thank you, Sir Guard", she said politely as the guard saluted her, "Now, I will be in my chambers for the remainder of the night. I would not like to be disturbed unless there is an absolute emergency, understand?"

"Understood clearly", he said back, "You have a good night, Princess Twilight". Twilight bowed a bit.

"You as well", she said, "Dismissed". The guard saluted again and walked off and down the stairs. Before closing her door, Twilight looked up and down the long hallway, making sure she was completely alone.

Seeing no one else around, Twilight quickly hopped into her bedchamber, closing and locking the door. She then slid her back against the door until she was sitting on the carpeted floor, sighing very loudly. Nothing soothed Twilight's nerves more than relaxation, besides reading, and after running around, doing errands with Celestia all day, that was just what she needed. But, she had her own way of relaxation, and she was going to do it. She levitated her purple saddlebag and pulled out her special and secret item, and it wasn't a book.

Twilight smiled as she stared at the object: a large, purple, disposable diaper, with a pattern of her cutie mark on it. Yep, foal fetish. That was her main source of relaxation. She rubbed the pillow-soft garment against her face, shakily sighing at it. She knew she would be teasing herself if she waited any longer, so she decided to start. She walked over to the bed and laid the diaper flat on it, exposing the soft, cotton inside. Then, she grabbed a bottle of foal powder from her saddlebag and sprinkled a large amount on the padding. After that, she raised herself onto the bed, sitting on the back of the diaper. Lastly, she pulled the front of the diaper over her private area and taped it up, using her hooves instead of her magic to get the full experience. She smiled as she looked in her full-body mirror, but something was missing.

Knowing what is was, Twilight went back into her saddlebag and pulled out her attire. A big pair of purple, flannel pajamas, that covered every part of her body, including her hooves, and even had a flap between the crotch for diaper changes. She smiled and slid the pajamas on herself, snapping the buttons to the flap to cover her diaper. She squealed with excitement, loving the warm feeling of the pajamas. She sat down on her bed against the bed frame, giggling to herself. After a while, she began to get lonely, so she decided to play with a friend. She used her magic to open a small chest next to her saddlebag, smiling as she levitated her Smarty Pants doll over to her and into hooves, hugging it tight.

"Oh, Smarty Pants", she said, "I love you so much!" In her mind, she imagined Smarty Pants talking back to her.

"I love you too, Twily", Smarty Pants said, planting a soft kiss on her cheek, "Even though you used me to start a riot in Ponyville".

"Smarty Pants...", Twilight said, feeling a bit offended, "You're still holding that stupid grudge? That was over two years ago".

"But Twily", Smarty Pants said, "You infected me with that 'Want it, Need it' spell, and I was fought over by hundreds of other ponies! Then, that red stallion kidnapped me and I became Winona's chew toy! If you hadn't found me laying in the orchard, I would be a headless body right now!"

"I know", Twilight said, "And I'm sorry. I've had you since Mommy made you for me when I was a baby, and I'll never let anypony hurt you". Twilight gave the doll a small nuzzle on her cheek, making her smile and wipe a pretend tear from her button-eye.

"I love you, Twily", she said.

"I love you too, Smarty Pants", Twilight said. Suddenly, Twilight felt an uncomfortable pressure in her bladder from the four glasses of lemonade she purposely had with dinner. She smiled and looked at Smarty Pants. "Uh... Smarty Pants?"

"Yes, Twily?", Smarty Pants said.

"I really have to go pee-pee", Twilight said, playfully crossing her hind legs, "Do you mind?"

"Not at all, Twily", Smarty Pants said, "Do what you have to. I won't look".

Twilight giggled as Smarty Pants held one of her front legs over her button-eyes to give Twilight some privacy. Twilight tucked her lower body underneath the multiple blankets and relaxed. She didn't push, she just relaxed and let her bladder release when it wanted to. Soon, she felt herself starting to pee into her purple diaper, sighing loudly as she felt, and heard, the warm urine spray into the diaper she was wearing. After she finished, she sighed once more and looked over at Smarty Pants, who's pink button-eye was peeking right at Twilight's crotch. Twilight gasped and covered herself playfully.

"Smarty Pants~~~!", she whined playfully, "You said you wouldn't look! It's rude to watch another pony make potty!"

"S-sorry, Twily...", Smarty Pants said, "I just got curious". Twilight giggled and nuzzled Smarty Pants.

"It's OK, Smarty Pants", Twilight said, "I understand. Besides, you've seen me go potty before. Don't you remember when I was going potty training? You sang to me and helped me go potty. I couldn't even tinkle a drop without your beautiful singing". Smarty Pants blushed.

"Twily~~", she whined lightly, "You're making me blush!" Twilight smiled and yawned, rubbing her lavender eyes.

"Smarty Pants?", she said, "I'm getting sleepy. Is it OK if I go ny-ny?" Smarty Pants yawned as well.

"Only if I can go too", she mumbled. Twilight giggled.

"OK", Twilight said. She tucked herself in deeper into the comforters, using Smarty Pants as a pillow. It didn't bother Smarty Pants though, because Twilight's thick mane was as comfy as a blanket, no matter how heavy her head was.

"Hey, Twily?", Smarty Pants said, "When we get back home, can I sleep with you instead of in that dark and scary chest?"

"Of course you can", Twilight said, "As long as you don't wet the bed". Smarty Pants raised her eyebrow at Twilight.

"I can't wet the bed, Twily", she said, "I can't even tinkle".

"Exactly", Twilight said. It took Smarty Pants a while to understand Twilight's joke.

"Ohhhhhhh", Smarty Pants said, giggling, "I get it". Twilight giggled also and turned the off the lamp. The only light that was in the room was the beautiful Moonlight, lightly shining through the window. Twilight snuggled herself under the blankets.

"Goodnight, Smarty Pants", she said, "I love you". She slowly drifted off into Dreamland.

Meanwhile, in the bedchamber across Twilight's...

Princess Celestia, having just finished a glorious and pleasant seven-hour bubble bath, was laying on the purple rug she uses as a bed, looking at old photo albums and having a slice of cake before bed. She loved looking at old photos of anything, but her favorite ones were the ones with Young Twilight and herself. She had taken and saved several pictures from Twilight's fillyhood. From the day she first moved into the Castle to the day she moved to Ponyville, she had lots. There was even the time she caught Twilight sneaking snacks from the kitchen, and fell face-first into a giant vanilla cake, covering her face in frosting. That one made Celestia giggle every time she saw it.

"Oh, Twilight Sparkle...", she mumbled low to herself, "Why did you have to grow up so fast? You were so playful and funny during your years under the roofs of this Castle. But now, you're a grown Princess mare, and you have your own Castle in Ponyville now. You've been doing so good without my help, and all you need is the help from your friends. *sigh* I wish you were young again, just so we could go back to those good times".

Celestia finished her cake, but before going to bed, she got up from the rug and waked across the hall to her student's bedchamber. Pressing her ear against the door lightly, she heard nothing but soft breathing and light snoring. Twilight was sleeping. Being as quiet as a mouse, she unlocked the door and let herself in. It was dark, but the Moonlight help her see her student sleeping peacefully, with Smarty Pants laying underneath her head.

Celestia smiled and walked slowly over to her sleeping student, trying not to make too much noise from the clopping sound of her hooves. Once she got to the bed, a very strong smell of ammonia and urine combined reached her muzzle, making her muzzle twitch a bit. It didn't bother her much, because even though she was a Princess, she did have her own little bed-wettings once in a while after too much lemonade before bed. What confused her was the smell was coming from Twilight, and the bed was dry.

Curious, the Sun Princess slowly peeled the covers from the sleeping mare, seeing a surprising sight. Twilight was wearing a pair of foal pajamas that looked like it had been custom made for her. Even more curious, she undid the flap to her pajamas, exposing her diaper. Celestia was surprised, but happy. Twilight was sleeping like a baby, dressed like a baby, and had wet her diaper like a baby. She had gotten her wish. Twilight had foal fetish, and liked acting like a baby.

Smiling, Celestia went into Twilight's saddlebag and changed her into a nice, clean diaper. Then, she threw the wet diaper in the wastebasket and placed Smarty Pants in her hoof, levitating a pillow behind her head. After that, she left the room and closed the door, smiling with a request for Twilight she would never forget.

~~~~~~~~~~

The next morning, the beautiful Sunlight shined lightly in Twilight's face, waking the lavender mare up. She yawned loudly and rubbed her eyes, opening her eyes. She saw Smarty Pants in her hoof and smiled, hugging her tight. Smiling wider, she reached down and poked at her diaper, wanting to feel the wetness. But, she didn't. Her diaper was completely dry. Twilight became confused, because she remembered wetting her diaper like the bottom of her hoof.

Twilight then became paranoid. If she wet her diaper, but didn't remember changing herself, that means someone else did, and saw her fetish. It could have been a maid, a guard, or... even Princess Celestia. Twilight started to get up and quickly change out of her attire, but she saw a familiar golden aura start to unlock the door. In a panic, she quickly got back into the bed and used the multiple blankets to cover everything but her head as the door opened. Princess Celestia had waked in, smiling brightly at her student.

"Good morning, Twilight Sparkle", she said, her voice sounding marvelous, "How are we feeling this fine morning?"

"G-great, Princess Celestia", Twilight said, trying hard not to sound suspicious.

"Did you sleep well?", Celestia asked.

"Like a baby", Twilight said, starting to shiver. Celestia smiled and nuzzled her student.

"Well, breakfast is to be served in ten minutes", she said, "I came up here to wake you".

"I'll be down in about five minutes", Twilight said.

"So", Celestia said, "I see you have a foal fetish". Hearing that made Twilight completely paranoid and begin to sweat heavily.

"Wh-what are y-you talking about, P-Princess?", she said, "I don't have a-" Before Twilight could finish her sentence, Celestia quickly ripped the blankets off of the nervous mare, catching her dead in her lie.

"You were saying?", Celestia said, teasing the mare. Twilight's eyes welled up with tears. Her only secret was exposed, by the worst of all the ponies she knew. Celestia knew her only secret. Twilight buried herself in the covers, crying into Smarty Pants' stomach. Celestia instantly felt bad.

"Twilight?", she said, sitting down next to the sad Alicorn, "What's wrong?"

"Leave me alone, Princess!", Twilight said.

"Twilight, look at me", Celestia said, her voice calm, but demanding. Twilight uncovered herself and looked into Celestia's magenta eyes. "Now, what's wrong?"

"You think I'm disgusting, that's what!", Twilight said, trying hard to keep her voice calm.

"Why would I think you're disgusting?", Celestia asked, "Because of your fetish?"

"What do you think?!... your highness", Twilight said, adding that last part, remembering she was talking to a higher Royal than herself. Celestia pulled Twilight towards her, letting her rest her head in her lap.

"Twilight...", she said, "I would never think of you badly because of a little fetish. This is your decision, and I shouldn't act sour toward you because of it". Twilight looked up at her, tears flowing from her lavender eyes.

"Y-you're not mad, Princess?", she asked.

"Of course not, my student", Celestia said, "Fetishes are completely normal, no matter what. In fact..." She stopped herself and looked around, making sure it was just her and Twilight around. "Luna and I both had a foal fetish once". Hearing that surprised Twilight a bit.

"You did?", she said, hardly able to believe that.

"Yes", Celestia said, "After we lost Mother and Father in the Equestrian War against the griffons, we fell into a deep depression. The only thing that helped us calm down was foal fetish. We had one for almost 500 years before we were able to get over them".

"Wow...", Twilight said, "Princess Celestia and Princess Luna had foal fetishes".

"Yes", Celestia said, "In fact, I saw you last night in your little getup. You were sleeping peacefully, so I changed your diaper so you wouldn't wake up and smell strongly of urine. I actually think your fetish is a little cute". Twilight blushed heavily.

"Well... thank you... Princess", she said. Then, Celestia smiled.

"Twilight", she said, "May I ask you something?"

"Sure, Princess", Twilight said.

"Well... before I saw you in your little jammies", Celestia said, "I wished that you could be young again, and seeing you in this babyish attire could do that. My student... would you please allow me to have my wish?"

"What do you mean?", Twilight asked.

"Well, you like acting like a foal, correct?", Celestia asked. Twilight nodded happily. "Well, foals need mommies to take care of them, right?"

"Yeah... but what does that have to...?", Twilight said, before what Celestia said finally caught on, "You mean...?"

"Yes", Celestia said, "Will you allow me to baby you, as if you were my own filly?" Twilight blushed and looked down.

"I... I don't know what to say...", she said, "I... I..."

"It's your choice, Twilight Sparkle", Celestia said, "It's a request, not an order".

Twilight thought about it for a minute. Acting like a foal might have been great, but being treated like one sounded weird, especially by her mentor and not by her mother. Though she did want to, she couldn't see herself saying yes. But, at the same time, it did sound tempting. Plus, after all of the mentoring, studying, and supporting Celestia did for her, Twilight knew giving Celestia her wish was all she needed to make up for it. Plus, she did owe Celestia for not being sent back to Magic Kindergarten after the riot she caused in Ponyville.

Taking a deep breath, Twilight replied, "Yes, Princess".

"What was that?", Celestia said.

"You can baby me", Twilight said, "But, only under one condition".

"What's that?", Celestia said.

"Can you call me 'Twily'?", Twilight asked, "I like being called that". Celestia smiled.

"Sure I can", she said, "Only if you call me 'Mommy'". Twilight smiled and happily nodded. "Alright then, breakfast is to be served in a few minutes. Let's go... Twily". Twilight nodded and started to walk out with Celestia, but heard Smarty Pants clear her throat.

"Wait... uh... Mommy", Twilight said, trying to get used to saying that, "Can Smarty Pants come too? She get's scared and lonely without me".

"Of course she can", Celestia said, using her magic to levitate the doll on Twilight's back, "It's always good to eat with a friend". Twilight giggled and followed her "Mommy" downstairs to the dining room.

Once they got there, Twilight sat down in one of the cushioned seats as Celestia sat across from her, placing Smarty Pants in the seat next to her. Twilight lightly bounced up and down on the cushion like a baby as she patiently waited for her breakfast, making Celestia chuckle a bit. Soon, the chefs came out and gave both of the Alicorns a plate of pancakes and filled their mugs with coffee. Twilight smiled as she stared at her pancakes. They were chocolate chip pancakes, with caramel sauce, extra oats, whipped cream, diced hay, and sprinkles, her childhood favorite. The delicious pancakes made Twilight's mouth water, and she wasn't about to just sit there and stare at them, either. She used her magic to levitate her fork and knife, but before she could cut herself a piece, her silverware was stolen from her by a golden aura.

"Ah ah ah, Twily", Celestia said, "Babies can't play with knives or forks. I don't want my baby getting any owwies".

"But Mommy!", Twilight said, pounding on the table with her hooves like a foal, "I'm hungry!"

"I know you are", Celestia said, "So I'm going to feed you". Celestia used the knife and fork to cut Twilight's pancakes into little pieces, while Twilight waited patiently, hugging Smarty Pants tight as she did. After she finished, Celestia placed a piece on the fork and held it out to Twilight. Even though she wanted it, Twilight decided to play a little. She made a disgusted face and turned her head, winking at Celestia afterwards. Celestia chuckled, catching on to Twilight's joke.

"Come on, Twily", she said, lightly poking Twilight's lips with the fork, "You're not leaving this table until everything on that plate is in your tummy, so I suggest you eat up". Twilight opened her mouth and allowed Celestia to place the pancake in her mouth. The very sweet flavor assaulted Twilight's taste buds, hypnotizing Twilight.

"Mmm...", Twilight mumbled, making Celestia smile.

"That's a good filly", she said, "Eating her breakfast like she's supposed to". Over and over Celestia fed Twilight her pancakes, while at the same time feeding herself. Twilight felt happiness on the inside and outside, being fed like a baby. She thanked herself for accepting Celestia's offer. Anyway, Twilight soon finished the last bite of her pancakes and wiped the caramel and whipped cream from her mouth. Then, she felt a little thirsty. She reached for her mug of coffee, but a golden aura slid it across the table to Celestia.

"Babies can't have coffee", Celestia said, "If I were to give you coffee, you'd be bouncing off the walls for hours". With only two gulps, Celestia completely downed Twilight's coffee, making the adult foal look at the floor sad. "Aww... no need to be sad, Twily. I have something else you may have to drink". Twilight smiled. "But, we'll have to go upstairs first. Follow me to my chambers, please". After Celestia called for the maids to collect the dishes, she walked upstairs, Twilight and Smarty Pants following.

Once they got to Celestia's bedchamber, Celestia let Twilight in, closing and locking the door behind her. After seeing they were both alone in the chamber, Celestia laid down on her side on her bed-rug, exposing her underside. Twilight sat down on the rug, facing Celestia's underside.

"So...", she said, "What am I going to drink?"

"You're looking at it", Celestia said, stretching her hind legs to expose her underside a little more.

"What do you mean?", Twilight asked. She looked at Celestia's underside, seeing two large, pink nipples easily visible through her white coat. It didn't take an egghead to catch what Celestia was saying then. Twilight gasped a little. "Are you saying...?"

"Yes", Celestia said, "It's healthy for a baby to nurse from its mother". Twilight nervously rubbed the back of her neck.

"Uh... uh...", she said, hardly able speak.

"I know you want to, Twily", Celestia said, "I can sense your excitement".

"Well... yeah... but...", Twilight said, "It... doesn't seem right".

"Of course it doesn't", Celestia said, "But that doesn't mean it has to be, right? It's only you and I in this chamber, and nopony else will know".

Twilight felt her throat starting to become sore as her thirst became more and more heavy. She did want to nurse from Celestia and see how it felt, but it also made her feel awkward. Celestia wanted Twilight to suckle from her, even though they weren't real mother and daughter. Twilight figured it might have been just like suckling a foal bottle, but a little different. She felt her mouth become dry as she kept sitting there, so she finally worked up the courage to do it.

"O... OK", she said, "I'll do it, but please don't tell anypony else! Not even Princess Luna or Cadence or Shining Armor!"

"I won't, Twily", Celestia said, "Our little secret, I promise".

Twilight exhaled lightly and laid down on her stomach, her lips about just an inch away from one of Celestia's mounds. Twilight gulped and stared at her mentor's impressive mounds. She was starting to feel very uneasy about the idea, but her thirst was extreme, and she already said she would do it. She leaned forward a little and gave the teat a small lick, making Celestia squeal lightly. It didn't taste too bad and Twilight didn't get any hairs in her mouth, so she finally started. She latched onto the nipple, comforting her mouth to the size, getting a small squirt of breast milk for her effort. She took a few seconds to let the taste marinate with her taste buds.

Twilight's eyes popped open in surprise. The milk tasted great, better than any other milk she had ever tasted. It was warm, sweet, and creamy, and it felt like heaven as she continued to drink the warm milk. Even though it was a little heavy in viscosity, she still loved it. She began to pick up the pace, suckling a normal flow of milk from her mentor's teats. It did feel like suckling from a foal bottle, but better. Celestia let a few light moans out as she felt her milk exit her breasts and enter Twilight's mouth.

"That's it, Twily", she said, lightly petting Twilight's mane as she drank, "Drink up. You're gonna big so big and strong like your mommy". She continued to coo at Twilight as she drank. After about two minutes, Twilight had filled her belly to fullness and slowly pulled away, licking the leaking drops away from Celestia's teat, a bit of it around her lips. Celestia smiled and wiped the cream from her student's mouth.

"Did my baby get enough?", she playfully asked.

"Milky good!", Twilight said, expelling a few drops from her mouth, "Tummy full!" Celestia smiled.

"I'm glad you got enough", she said, "Anytime you desire more, just let me know. I'm holding more milk than a dairy cow". Twilight giggled and nodded. "Now, would Little Twily like to play with her toys?"

"Toys?", Twilight asked, "I didn't bring any-" Celestia placed her hoof over Twilight's mouth before she could finish.

"You didn't have to, Sweetie", she said, "Because I've got some you may play with". Twilight smiled as Celestia went into her closet and pulled out several toys, setting them in front of her student. Twilight smiled at the tiny mountain of dolls and blocks in front of her.

"Those look so pretty", she said.

"Thank you", Celestia said, "Now, play nice with those. They were given to me by my mother, and I've had them since my childhood". Twilight nodded and played with the toys, while Celestia sat at her desk and completed some paperwork. After about an hour, Twilight began to get lonely again.

"Mommy", she said. Celestia looked up at her student.

"Yes, Twily?", she asked. Twilight held one of the dolls out to her "mother".

"Play with me, please?", Twilight asked. Celestia smiled and walked over to her "baby", sitting down next to her.

"Sure", she said, taking the doll. The two mares played with the toys for several hours, enjoying the fun. But, after about another hour, Celestia stood up.

"OK, Twily", she said, "Mommy has to go to court now". She started to walk away, but Twilight grabbed one of her hind legs before she could leave. Celestia looked down at her student, seeing puppy-dog eyes on her face. "Aww... does somepony not want their mommy to leave?" Twilight shook her head. "It's OK, Twily. Today's Saturday. On weekends, court only lasts two hours instead of six. I'll be back in no time".

"OK, Mommy", Twilight said, letting go of Celestia and going back to playing. Celestia smiled and leaned down, kissing the top of Twilight's head and walking down to the Castle Courtroom.

~~~~~~~~~~

Even though court was only two hours, it still felt like six to Celestia, since she had been doing it for over 1000 years. Once her final case ended, she banged her gavel and almost ran back up to her bedchamber, once she got to her chamber, she opened the door and walked in, closing and locking the door behind her. She smiled as she saw her student still happily playing with the toys.

"I'm back, Twily", she said, "You know what that-" She cut herself off when a very foul smell she was familiar with attacked her muzzle. She looked at the back of Twilight's pajamas, seeing a large bulge in the center. "Twily?" Twilight turned to face Celestia.

"Yes, Mommy?", she asked.

"Did you... mess yourself while I was gone?", Celestia asked. Even though she knew she did, Twilight decided to play a little.

"No, Mommy", she said, "I didn't make a messy". Celestia kept herself from laughing.

"Really?", she said, "Then what smells so stinky, hmm?"

"I don't smell a stinky", Twilight said, giggling.

"Come on, Twily", Celestia said, "I know you have a poopy diaper right now".

"No I don't", Twily said.

"Tell the truth", Celestia said, "Unless you want your best friends to know about your fetish?" Even though Twilight knew Celestia wasn't serious, she decided to fess up.

"I make a big stinky poo-poo in my diapee!", she said, making her voice sound as babyish as she could. Celestia smiled.

"Alright", she said, "Let's get you changed". Celestia walked into Twilight's bedchamber to change her, Twilight following. After getting cleaned up, Twilight followed Celestia back into Celestia's chamber and sat down on the rug, yawning loudly and fluttering her eyes. Celestia smiled.

"Aww...", she said, "Is my little filly getting sleepy?" Twilight did want a nap, but decided to play one more time.

"No", she said, "Me not sleepy". Celestia chuckled again.

"You're not?", Celestia said. Twilight shook her head. "Then you wouldn't be sleepy if I put this blanket over you?" She used her magic to grab her biggest comforter and place it over the sleepy mare. Twilight yawned again and laid down on her stomach, but continued to fight.

"Still not... sleepy", she said, her voice getting weaker.

"Well, what if I let Smarty Pants lay with you?", Celestia said, levitating Smarty Pants over to Twilight. Twilight couldn't help but grab her and hold her close to herself. Feeling the doll's soft touch, Twilight became more sleepy, but was still able to fight it as she refused the urge to get comfortable.

"Is that all...*yawn*...you got?", she said. Celestia then levitated her biggest pillow over to Twilight. Twilight slowly rested her head on it and sighed, barely able to keep her eyes open. "I can...*yawn*...stay awake, Mommy". Celestia saw that Twilight was a fighter, so she decided to use her secret weapon, that she had gotten from Fluttershy.

"If your not tired", she said, "Then you would be able to stay awake if I sing a lullaby?"

"A lullaby?", Twilight asked.

Celestia sat down next to Twilight and sang "Hush Now, Quiet Now" softly in her ear, lightly petting her mane. That did it. The soft sound of Celestia's beautiful singing voice, plus the warmth and softness of the blanket, was just enough to put Twilight asleep. She was completely comfortable, and wasn't able to keep her eyes open. She could feel herself peeing her diaper from the relaxing, but didn't care. She slowly drifted off to sleep with one final yawn. Celestia smiled and kissed Twilight's muzzle as she slept.

"Have a good nap, my filly", she said. She then walked back over to her desk to finish her paperwork. As she stared at the sleeping adult foal she wondered how to make Twilight's fetish a little more better.

What if... a playmate was added?

Pinkie Pie

Twilight Sparkle woke up once again and yawned loudly. Instead of waking up on her own however, she woke up to really high-pitched giggling. She opened her eyes and looked over at Smarty Pants.

"Smarty Pants...", she mumbled, "Stop laughing. I'm trying to sleep". Smarty Pants groaned.

"I'm not laughing, Twily", she said, "I just woke up too".

"Then, if it's not you, then who is it?", Twilight asked, sitting up. Suddenly, the giggling sounded very familiar, and she knew exactly who it was coming from. "Oh no. Not her".

"TWILY!", a very high-pitched voice said. Next thing Twilight knew, she was tackled onto the rug and hugged very tight. A pink mane blocked her view, but she knew exactly who it was.

"P-Pinkie Pie!", Twilight said, trying hard to struggle out of the Earth Pony's grasp, "Let go of me!". Pinkie Pie let go of Twilight, giggling at her.

"I couldn't help it, Twily!", she said, "You're so cuddly!" Twilight caught her breath and looked at her best friend. She was wearing a pink flannel onesie and the outline of her pink diaper could easily be seen.

"Yeah, whatever", Twilight said. She then popped her eyes open in surprise, as Pinkie Pie had just responded perfectly. "Wait, you're not regressed?!"

"Nope!", Pinkie Pie said, "I'm still me! Me and my grown-up mind!" Twilight was two seconds away from panicking before Celestia walked in, having just raised the Sun.

"Good morning, my little filly", she said, kissing her on the cheek.

"Princess Celestia!", Twilight whined, "Don't call me that! Not in front of her!"

"What's wrong?", Celestia said, "She's one of your best friends".

"But she's not regressed!", Twilight said, "She knows everything now! My secret is out!"

"Nuh-uh!", Pinkie said, "Not if I don't tell!" Twilight looked over at her diapered friend.

"What?", she asked.

"I'll explain", Celestia said, "You see, I wanted another one of your friends to play along with you again, so I chose Pinkie Pie. However, unlike Rarity, she wasn't hard to persuade, plus has the same fetish you do, so I allowed her to spend the night here".

"And I won't tell anypony!", Pinkie sweetly said, "I Pinkie promised Princess Celestia. You know I never have, and never will break a Pinkie Promise!" Twilight nervously rubbed the back of her neck.

"B-but, I didn't know you have a foal fetish too", Twilight said.

"Oh yeah, I do!", Pinkie proudly said, "It's a long story, too. See, I never got to wear diapers, not even as a foal. Growing up on a rock farm, my parents couldn't afford diapers or toys or most of the stuff foals need. Me and my family usually had to go on a pile of pebbles or in a bush. I didn't mind for years, but every time I babysit Pound Cake and Pumpkin Cake, they remind me what I never had. So, I grabbed one of Pumpkin Cake's diapers and tried it on, and it surprisingly fit me. Once it was on me, I never wanted to take it off. Over time, I became more and more attached to acting like a foal. Diapers are so comfy and the fact that I don't have to go to the toilet to relieve myself is great".

"Isn't it?", Twilight said back with a smile.

"Yeah!", Pinkie said, "In fact, I like wetting and messing diapers. It's gives them a warm feeling, and I don't care how stinky it gets".

"Me neither", Twilight said, "Wow Pinkie. You and I strangely have a lot in common". Celestia smiled and let the mares play with each other as Pinkie continued to talk.

"Yeah", Pinkie said, nuzzling Twilight, "Oh, and someone wants to meet you!" Pinkie reached into her diaper bag and pulled out the rubber chicken that her friend, Cheese Sandwich gave her. "Twily, this is Boneless. He's my friend". Twilight giggled and played along.

"Hi, Boneless", Twilight said, "I'm Twily".

"What was that, Boneless?", Pinkie said, leaning her ear towards her rubber chicken, "Boneless wants to meet your friend". Twilight smiled and crawled over to Smarty Pants.

"Smarty Pants", she whispered, lightly tapping her shoulder.

"*yawn* Yes, Twily?", Smarty Pants sleepily said.

"Wake up", she said, "Somepony wants to meet you". Smarty Pants yawned again.

"OK", she said, holding her hooves up to Twilight. Twilight smiled and carried Smarty Pants over to Pinkie and Boneless. "Boneless, this is Smarty Pants. She's been my friend ever since I was only three months old". Pinkie smiled and this time let Boneless to the talking.

"That's nice", he said, "I was recently given to Pinkie after my former owner, Cheese Sandwich visited Ponyville. By the way, Pinkie has a huge crush on Ch-"

"Anyway!", Pinkie said, cutting Boneless off, "Boneless, how about we let Smarty Pants Talk?" Smarty Pants smiled.

"Nice to meet you, Boneless", she said, "I'm Smarty Pants. I like candy, reading books, oats, research, and doing homework".

"You sound like a nerd", Boneless said, very lightly offending Smarty Pants.

"Boneless!", Pinkie said, smacking Boneless' tail feathers, "Don't say that! She has her hobbies, and you have yours, OK?" Boneless sighed.

"Yes, Pinkie", he said.

"Now, apologize to Smarty Pants", Pinkie said.

"I'm sorry", Boneless said.

"It's OK, Boneless", Smarty Pants said, "By the way, I know what you were going to say. Well, Twily has an even bigger crush on Fl-"

"So!", Twilight said, interrupting Smarty Pants, "Who's hungry?"

"I could eat", Pinkie said.

"Mommy", Twilight said to Celestia, "When's breakfast?"

"In five minutes", Celestia said, "I was just letting you two play for a while".

"OK!", Pinkie said.

"Well, if you two are finished", Celestia said, "Follow me to the dining room". Twilight smiled and walked over to Celestia, Smarty Pants following her, while Pinkie continued to sit on the rug.

"Are you coming, Pinkie?", Twilight asked. Pinkie blushed a little, the pink color of her coat letting it slightly be seen.

"I... think I... made a pee-pee", she said.

"Well, would you like a change?", Celestia asked. Pinkie smiled and nodded. Celestia began to walk over to Pinkie, but Twilight stopped her.

"Mommy...", Twilight said, "Maybe I could change Pinkie?" Celestia smiled.

"Of course you may", Celestia said, "Only if Pinkie agrees". Pinkie smiled wide.

"Sure!", she said.

"Well, alright then", Celestia said, "I'll let you have your privacy. Just make sure to wash your hooves afterwards". Twilight smiled and nodded as Celestia walked out of the bedchamber, closing the door after herself. Twilight walked over to Pinkie as Pinkie hopped onto the changing table and laid down.

"So", Pinkie said, looking up at her friend, "Why do you wanna change me?"

"Well, it is kinda hard to change your own diapee", Twilight said, "And since you have the same fetish as me, I'm not really that uncomfortable with doing it. You can trust me, right?"

"Of course I can", Pinkie happily said, "I was just asking. But should we do it while our friends are watching?" Twilight looked at the stuffed animals.

"I won't look", Smarty Pants said, turning her back toward the mares.

"Me neither", Boneless said, turning his back toward the mares as well. Twilight smiled and changed Pinkie's wet diaper, small giggles coming from the party animal.

"Twily, you're tickling me!", Pinkie said, trying hard to keep still.

"I can't help it, Pinkie", Twilight said, "You don't want a rash, do you?"

"Oh no no no", Pinkie said, "Diapee rashes are a big no-no! They hurt bad!"

"I know", Twilight said, "I learned that the hard way. I stayed in a poopy diapee for six hours, and got a pretty bad one that spread from my tail to my... front".

"Owwie!", Pinkie said, just shivering at the thought, "Well, now we know not to stay in a yucky diapee for too long, no matter how comfy and stinky it gets".

"Correct", Twilight said, zipping Pinkie's onesie back up, "All clean, Pinkie". Pinkie sat up with joy.

"Thank you so much, Twily!", she said, "That's why you're my best friend!"

"Correct again, Pinkie", Twilight said. Pinkie then noticed a blush forming on Twilight's face.

"What's wrong, Twily?", she asked. But then, a small hissing noise answered it for her, making her giggle. "Looks like Twily needs a changie-wangie too!" Twilight chuckled and laid herself on the changing table.

"Yes", she said.

After Pinkie changed her best friend's diaper and zipped her onesie back up, they washed their hooves and grabbed their friends, walking down to the dining room and sitting down right next to each other. The cooks brought out the food and beverages and walked back into the kitchen. Each mare had gotten a plate of French toast and crispy hash-browns.

"Alright, my little fillies", Celestia said, placing her silk napkin in her lap, "Everyone be on their best behavior at the table, and I'll reward you".

"Yes, Mommy", the mares said. Celestia smiled and began eating her breakfast.

"Hey, Twily", Pinkie said, "Can I ask you something?"

"Sure", Twilight said.

"Well, we're babies", Pinkie said, "Babies don't know how to use knives and forks. So, you wanna feed each other?" Twilight almost squealed with joy.

"Sure!", she said. Twilight used her magic to cut Pinkie's toast into small squares while Pinkie used her hooves the best she could. Pinkie and Twilight then fork-fed each other their breakfast, speaking among themselves as they did.

"So", Twilight said, wiping a bit of syrup from her lips, "How's everything going with the bakery and such?"

"Pinkie Perfect!", Pinkie said, "We made a record-breaking sale yesterday! A.K. Yearling and Rainbow Dash came in and order soooo much cake and ice cream! We actually met the quota right after that!"

"A.K. Yearling was in Ponyville yesterday?", Twilight asked as Pinkie fed her another bite of toast.

"Yep!", Pinkie said, "They were talking about mixing the Rainbow Dash fan-club and the Daring Do fan-club together for a year". Twilight swallowed and fed Pinkie a bite with her magic.

"That'll sure please a lot of fans", she said, "It'll also be more crowded than the Grand Galloping Gala". Pinkie swallowed.

"Yeah!", Pinkie said, "So, how the whole 'Princess' thing going for you?"

"It's great", Twilight said, "It's a little tiring, and it gives me much more responsibilities, but I really like it. I just hope I can get a better control of these wings. I can't fly higher than six hooves off the ground". Pinkie fed Twilight again.

"Well, who cares about your wings?", she said, "You're a Princess now! Everypony knows you now, and you have your own Castle in Ponyville! You don't know how bad I wish to be a Princess!" Twilight fed Pinkie.

"I'm sure you'll get your time eventually", she said, "Just a warning, being a Princess isn't like you think it is. Sure, you can get your way all the time, but you still have to work, almost more than a middle-class pony".

"I work twelve hours a day, seven days a week, Twily", Pinkie said, "I think I can handle it". Twilight giggled.

"I guess you will", she said. Pinkie and Twilight fed each other the last bite of their breakfast, wiping each other's mouths as Celestia finished her own breakfast.

"Well, was everything enjoyable?", she asked.

"Mm-hmm!", the "foals" both said, cuddling their friends tightly in her hooves.

"Everypony at the table was on their best behavior", Celestia said, "So as promised, I will reward you".

"With what, Mommy?", Pinkie asked.

"How would you like to have a playtime at the park?", Celestia asked, "I do not have a court this morning, so I figured I would share my spare time with my fillies".

"You want us to go out in public dressed like this?", Twilight said, "What if somepony laughs at us?"

"Then I will deal with them", Celestia said, "But I assure you, nopony will laugh at you. Would they laugh at me?"

"Nope!", Pinkie said.

"Exactly", Celestia said, "So, would you, or not?" Twilight, Pinkie, Smarty Pants, and Boneless talked it over in a small huddle, making Celestia giggle once again. After about ten seconds, Pinkie and Twilight looked at Celestia again.

"Yes, Mommy", they simultaneously said. Celestia smiled.

"Well, alright then", she said, "But I cannot take you two out in public wearing onesies".

"Aww!", Twilight whined, hugging herself, "Why not? I love my onesie!"

"Me too!", Pinkie whined.

"I'm sure you do", Celestia said, "But flannel onesies are only supposed to be worn around the Castle. You would burn up very quickly out in the Sun wearing one".

"She's right...", Twilight said, feeling very dejected.

"But not to worry, my little ponies", Celestia said, "I have something else you and your sister may wear". Celestia got up from the table and walked back upstairs, everyone else following her. After they walked back into the bedchamber, Celestia went into the closet and pulled out two dressy, but comfortable dresses, one lavender, one pink. Pinkie smiled as the pink dress sparkled in her pupils.

"Ooh! That looks so pretty!", she said. Twilight smiled also.

"It does", she said. Celestia smiled again.

"Well, would you like to wear these?", she asked.

"Yeah!", Twilight and Pinkie said.

"Well then, reach for the Sun please!", Celestia said. Twilight and Pinkie raised their hooves to the shy as Celestia slid the dresses onto them, trying the laces in the back. Twilight and Pinkie then stood up and looked at each other, smiling. The dresses were sparkly and fit comfortably. They were a little small, which exposed their diapers at the bottom a little, but they didn't care. They loved the dresses.

"Thanks Mommy!", Twilight proudly said.

"Thanks Mommy!", Pinkie repeated. Celestia smiled.

"You're very welcome, my sweethearts", she said, "Alright, let's get you to the park". Celestia reached into her closet once more and pulled out an adult-foal stroller that was big enough to hold two ponies.

"Wow!", Twilight said, admiring the stroller, "When did you get that?!"

"After I asked Pinkie to play along with you and she accepted", Celestia said, "She and I went to the store and picked up a few items to get ready. So instead of having to walk all the way there, I'll push you there in this stroller". Pinkie smiled and jumped into the stroller.

"C'mon, Twily!", Pinkie said, patting the seat next to her, "We're losing Sunlight!"

"It's 11:00, Pinkie", Twilight said, "But I'm coming".

"Twily!", Smarty Pants yelled, "Don't forget me! I wanna go to the park too!"

"Oh, I almost forgot", Twilight said, grabbing Smarty Pants, "Smarty Pants loves to swing".

"Can I go too?", Boneless politely asked, "I like the slides".

Twilight smiled and grabbed Boneless, placing him in Pinkie's hooves. After that, she got into the other seat of the stroller and rested as Celestia's magic strapped them in. After pulling the flap over the top to black the light out of their eyes, Celestia left the Castle, pushing the stroller to the park. Pinkie hummed to herself as the ride continued, and Smarty Pants and Twilight whispered to each other.

"Twily?", Smarty Pants asked, wrapped in Twilight's feathery wing.

"Yes, Smarty Pants?", Twilight replied.

"I kinda like Pinkie Pie", Smarty Pants said, "She's funny". Twilight chuckled.

"I like her too", she said, "It's great to be able to share my fetish with somepony else". Smarty Pants frowned.

"I wish I can be an adult foal too", she said, "But I can't make a stinky diapee".

"Smarty Pants, you don't have to be able to make stinky diapees to be an adult foal", Twilight said, "All you need to do is act like one".

"But babies always go pee-pee and poo-poo in their diapees", Smarty Pants said.

"Sure...", Twilight said, "But that doesn't mean we have to".

"What do you mean?", Smarty Pants asked.

"Well, you can still eat baby food and drink from a baba, right?", Twilight asked. Smarty Pants nodded. "And you can wear a diapee and a onesie, right?" Smarty Pants nodded again. "Then you seem like an adult foal to me". Smarty Pants smiled.

"OK, Twily", she said, "As long as we stay friends".

"Smarty Pants...", Twilight said, "We can't be friends if you're an adult foal".

"What?!", Smarty Pants said, "But Twily, I love being your friend! I've been your friend ever since you were a real foal! I-!" Twilight covered Smarty Pants' mouth with her hoof.

"I wasn't finished", she said, "We can't be friends. If you're an adult foal, we'll be sisters". Smarty Pants smiled again.

"I would love being your sister!", Smarty Pants said, "Then we could always be together!"

"Of course", Twilight said, "I love you".

"I love you too", Smarty Pants said.

After a twenty-minute stroller ride, Celestia and the foals all reached the park. Luckily for them, it was completely empty, as it was a hot day, and most ponies wanted to stay inside an air-conditioned house. Anyway, Celestia stopped pushing the stroller at the park bench and sat down, using her magic to unstrap the foals and allow them out of the stroller.

"Thanks for the ride, Mommy", Twilight said. Celestia smiled.

"You're welcome, Twily", Celestia said, "Alright, I'm going to sit here and read my book while you play. You must stay inside of the park's fence and if there's anything you need, you may come get me". Pinkie and Twilight nodded and walked away from Celestia, taking Boneless and Smarty Pants with her. Once they were far enough away from Celestia, they spoke again.

"So, Pinkie", Twilight said, "What should we do first?"

"Sandbox!", Boneless said with cheer, "I wanna play in the sandbox!"

"That sounds like fun!", Smarty Pants agreed, "Twily, can we please go play in the sandbox?" Twilight smiled.

"Of course we can, Smarty Pants", she said, "Pinkie, would you like to play in the sandbox?" Pinkie smiled as well.

"Sure!", she said. Twilight, Pinkie, Smarty Pants, and Boneless all walked to the sandbox to play. Once they got there, they all sat down in the warm sand, and Twilight and Pinkie kept their hind legs closed to avoid raking sand into their diapers.

"So", Boneless said, "What should we do first?"

"How about a sandcastle contest?", Smarty Pants suggested, "Whoever can make the best sandcastle wins!"

"Sounds fun, Smarty Pants!", Pinkie said, "But, are we on teams, or every mare for herself?"

"How about I team with Boneless, and you team with Smarty Pants?", Twilight said to Pinkie.

"Sure!", Pinkie said.

"But Twily~!", Smarty Pants whined, "I wanna be on your team!"

"I know", Twilight said, "But if we're all going to play together, we have to see if we can all get along. So, I'm teaming with Pinkie's friend, and Pinkie's gonna team with you, OK?"

"OK, Twily...", Smarty Pants said. Pinkie picked up Smarty Pants and hugged her.

"Don't worry, Smarty Pants!", she said, "You and me can work together just as good as you and Twilight!" Twilight chuckled and held Boneless in her lap. "OK! Let's build our sandcastles!"

For the next ten minutes, they all made their sandcastles the best they could, hoping to win. Once they were finished, they started inspecting each other's sandcastles. But, neither team could choose a winner. Both castles were magnificently built, with great accessories. Pinkie and Smarty Pants had added seashells as windows and doors, while Twilight and Boneless had added a drawbridge and a tiny moat using a water bottle.

"Uh... maybe you win?", Boneless said.

"No way!", Pinkie said, "You win! That moat is cool!"

"But the seashells bring out your castle so well", Twilight said.

"Why don't we go get Mommy to decide?", Smarty Pants suggested.

"No", Twilight said, "Mommy's trying to enjoy her free time. We shouldn't bother her".

"Then how do we decide who wins?", Smarty Pants asked. That's when Twilight spotted a blue and white mare walking toward the fence, humming a tune to herself as she walked. Twilight then began to panic.

"Oh no!", Twilight said.

"What's wrong, Twily?", Pinkie asked.

"It's Minuette!", Twilight said, "She's walking over here!"

"What's wrong with that?", Pinkie said, "She's our friend".

"But she's going to see us!", Twilight said, "She can't see me dressed like this! She'll make fun of me, and you! We gotta get out of h-!"

"Twilight? Pinkie Pie?", Minuette said, having walked up to the fence.

"Hi Minuette!", Pinkie happily said.

"It is you!", Minuette said, "Hi!" Pinkie hugged her best friend.

"Uh... hi, Minuette...", Twilight said, trying hard to hide her diaper.

"Why didn't you tell me you were in Canterlot?", Minuette said, "I wanna play with..." She then noticed the diaper around Pinkie's waist. "Wait... Pinkie... are you wearing... a diaper?"

"Yeah!", Pinkie said, "See, I'm playing with Twilight because we both have-!"

"It's an experiment!", Twilight said, cutting Pinkie off, "Pinkie's helping me with an experiment that requires her to wear a diaper".

"But you're wearing one too, Twilight", Minuette said.

"Oh... uh...", Twilight said, trying to stall. But it was too late.

"Twilight... do you and Pinkie...", Minuette said, "Like acting like... babies?"

"*sigh*... yes...", Twilight confessed. But then, Minuette smiled, to the surprise of Twilight.

"Aww!", she said, "That's so cute!"

"What?", Twilight said.

"I said that's cute!", Minuette said, "Seeing you two dressed like that reminds me of when you and I were all toddlers in kindergarten".

"Oh...", Twilight said.

"Hey, how about a selfie?", Minuette said, "Just for memory lane?"

"Sure!", Pinkie said, "Twily?" Twilight smiled.

"OK", she said, "But only to ourselves". Minuette smiled and pulled out her cellphone. One selfie later, Minuette smiled.

"That's so my wallpaper!", she said. That's when they all saw an ice cream carriage ride by, playing a colorful tune. Pinkie instantly stood up.

"Ice cream!", she yelled. Pinkie would have dashed off fast enough to make it to Manehattan in two seconds if Twilight hadn't grabbed her tail.

"Pinkie...", she said, "We don't have any bits to get any".

"Oh... right...", Pinkie said, sounding very dejected.

"No need!", Minuette said, "I'll pay for all of us!"

"Oh Minuette", Twilight said, "You don't have to-"

"Minuette, you're the best!", Pinkie said, "C'mon, Twily!" Twilight shrugged and walked over to the ice cream carriage.

"Good morning, everypony", the creamer said, "What can I get for you?" Twilight and Pinkie were about to say what they wanted, but Minuette beat them to it.

"One vanilla-oat-swirl pop, extra oats, one banana-mango fizzy stick, and one double-chocolaty-fudgesicle with a crispy hay coating", she said.

"All right", the creamer said, "Five bits, please". Minuette took out five bits and gave them to the creamer. After they all got their ice creams, they walked back into the fence.

"Minuette, thanks", Twilight said.

"You're welcome, Twilight", Minuette said, "I hope I ordered correctly".

"You did!", Pinkie said, having already finished three-quarters of her fudgesicle, chocolate all over her face. Minuette and Twilight giggled as they ate their ice creams. "Oh yeah! Minuette, which one of these sandcastles look better to you?" Minuette looked at the sandcastles.

"I think the one with the shells is better", she said. Pinkie smiled.

"Looks like I win, Twily!", she said.

"Yeah you do", Twilight said.

10:00 PM...

After everyone had dinner and had a bath, they all made it back into the bedchamber. Pinkie was nursing from Celestia after Twilight had persuaded her to. Since she had previously seen Twilight do it, she felt alright to do it also. Anyway, once Pinkie was finished, she slowly pulled away, a bit of cream leaking from her lips.

"Are you finished, Pinkie?", Celestia asked.

"Yes", Pinkie said, feeling just a little uncomfortable.

"Alright", Celestia said, "And I promise, nopony else will find out about this". Pinkie nodded. "Alright, I think it's bedtime for my fillies".

"Aww...", Twilight said, "Do we have to go to bed?"

"I'm afraid so, Twily", Celestia said, "I have court tomorrow".

"*sigh* OK", she said, "Um... Mommy?"

"Yes, Twily?", Celestia asked.

"I made a stinky mess in my diapee", Twilight said. The smell had reached Celestia's muzzle at that point.

"I made a stinky too", Pinkie said.

"Well then, let's get you cleaned up", Celestia said. Two changes later, Celestia placed the adult foals in the large crib and tucked them in with the white blanket. She then leaned down and gave them both a kiss on their cheeks. "Goodnight, my little angels".

"Night, Mommy", Twilight and Pinkie said. Celestia turned off the light and laid herself on her rug, sleeping peacefully.

"Pinkie...", Twilight said, "You made today fun". Pinkie blushed with flattery.

"So did you, Twily", Pinkie said. A small yawn came from them both. "Goodnight, Twily".

"Goodnight, Pinkie", Twilight said as they both fell asleep.

~~~~~~~~~~

The next morning, Pinkie Pie woke up in her own bed and yawned, scratching her face with her hind leg like a dog. She then saw a sparkly letter with a pink ribbon wrapped around it, sitting on her nightstand. She picked up the letter and opened it, reading softly to herself.

"Dear Pinkie Pie", she read, "I strongly thank you for playing along with Twilight as an adult foal. Now, I know you said I didn't have to give you a reward, but I gravely insisted and gave you the gift you've always desired for. But remember, you must keep Twilight's secret to yourself, for if you tell another soul, you will no longer her this gift. Yours, Princess Celestia".

"But... what gift?", Pinkie mumbled to herself. That's when she heard Mrs. Cake call her from downstairs. "Coming!" She walked downstairs and saw Mr. and Mrs. Cake all packed up, their foals with them. "Where are you going?"

"We've decided to pursue our dream of owning a bakery in Canterlot", Mr. Cake said, "Since a position opened up for us, we're moving there for the time in being". Pinkie gasped.

"But who's gonna look after Sugarcube Corner?!", Pinkie panicked. Mr. and Mrs. Cake smiled at each other, and then looked at Pinkie again.

"You are", Mrs. Cake said.

"What?", Pinkie asked.

"Carrot Cake and I are giving Sugarcube Corner to you", Mrs. Cake said.

"You mean... the whole bakery?!", Pinkie said, "It's all mine?!"

"Yes", Mr. Cake said, "Sugarcube Corner, and everything that stays here, is now yours". Pinkie pulled them both into a bone-crippling hug.

"Thank you thank you thank you!", she said, "I got a whole bakery to myself now!" She let go of Mr. and Mrs. Cake.

"Alright, we're going to go now", Mrs. Cake said, "But we will visit sometimes to check on you".

"I'll make Sugarcube Corner even better than it was!", Pinkie said.

"Well, good luck", Mr. Cake said, "And goodbye". Mr. and Mrs. Cake left the bakery, taking their stuff with them. Pinkie stared around in awe at her new bakery.

"Thank you so much, Princess Celestia!", she whispered to herself, "I Pinkie Promise I won't tell anypony else".
