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*
