Busted!

Princess Twilight Sparkle was at Canterlot Royal Castle, just finishing a dinner with her mentor and teacher, Princess Celestia, to celebrate her new royal place. Twilight was staying the night, so she could have all of the time she could with Celestia, for she knew that it would be a long time before she could get more. She savored every moment of time she got with Celestia, no matter what they were doing. After her dinner, Twilight began walking up to her old bedchamber she had as a filly, one of the Pegasus Royal Guards following her. Once she got there, she turned to the guard, as he bowed in front of her.

"Thank you, Sir Guard", Twilight said, as the guard rose, "Now, I'm very exhausted and will be in my chamber for the remainder of the night. Please do not disturb me, unless it's an absolute emergency".

"Understood", the guard said, "You have good night, Princess".

"You too. Dismissed". The guard saluted and walked away. Twilight opened the door and looked up and down the hallway, making sure nopony else was in there. The hallway was empty, just the way she liked it. Smiling, Twilight closed and locked the door, and sighed loudly, sliding her back against the door until she was in a sitting position. She had been waiting for this. A change to relax, after all of the running around she had to do with Celestia. But, just sitting around in her spare time wasn't all that was planning to do. She was planning to do something else, and reading books isn't what it is.

Smiling with anticipation, she walked over to her purple suitcase and pulled out something she was dying to wear: a thick, white, disposable diaper, made at the size for an adult. Just looking at the garment made Twilight excited. She pressed her muzzle against the diaper and inhaled deeply, enjoying the fresh foalish scents of a nursery. It smelled like baby powder on its own. Twilight giggled at the smell and walked over to her bed. She opened the diaper and laid it out flat. She got onto the bed and laid her flank on the back. She then levitated some foal powder and powdered her marehood. After that, she used her hooves to finish diapering herself, wanting to feel the full sensation. After finishing, she put the powder back and looked at herself in the full-body mirror. She smiled, liking the look of the diaper, but something was missing.

Knowing what is was, Twilight walked back over to her case and smiled at what she picked up a pair of hoofie pajamas, made with lavender flannel. Twilight smiled as she put on the pajamas. Then, she looked at herself again. Twilight squealed in joy at herself. She looked adorable.Going over to her case one more time, she pulled out a lavender pacifier. Twilight popped the pacifier into her mouth and happily suckled. She then walked over to her bed and sat down, resting her back against the frame. She suckled on her pacifier for a while. Then, feeling a little lonely, she looked over at the chest she had brought with her. Smiling, she used her magic to open it and levitated her Smarty Pants doll over to her. She hugged the doll tightly as she began to talk to it.

"Oh, Smarty Pants", she said, "I love you". In her mind, she imagined Smarty Pants speaking back to her.

"I love you too, Twily", Smarty Pants said, "Even though you used me to start a riot in Ponyville".

"Smarty Pants, you're still holding that grudge? That was about six months ago".

"But, Twily, you infected me with that 'Want it, Need it' spell, and I was nearly torn apart. It took Princess Celestia to stop it, and that red stallion took me from you, and I spent three weeks as Winona's chew toy. Do you know what you put me through?!"

"I know, and I'm sorry. You know I still love you, and I won't give you up".

"Well, can you at least let me sleep next to you at home and not in that dark and scary chest?"

"Sure. Anything for you". Twilight kissed Smarty Pants on her muzzle. Then, she felt her bladder aching for release from the twelve glasses of water she purposely had at dinner. She blushed as she looked at Smarty Pants again. "Umm... Smarty Pants?"

"Yes, Twily?"

"I... have to go pee-pee. Do you mind?"

"Not at all. Go ahead". Twilight smiled as she buried herself in the covers of her bed. Twilight didn't push, she just relaxed and let it happen. Soon, she felt her warm urine flow out of her and into the diaper. Twilight sighed loudly, loving the warmth and wetness happening inside of her diaper. Soon, her stream came to a stop. Twilight began poking at her wet diaper, feeling the puffiness. "Feel better, Twily?"

"Much better". Twilight hugged Smarty Pants again. Then, Twilight suddenly felt sleepy. The warmth from being buried under thick comforters, soft sheets, and her newly-wet diaper began to feel very relaxing to her. She yawned loudly and began to lightly rub Smarty Pants' mane. "Twily needs a nappy. Does Smarty Pants want one too?"

"Yes she does". Smarty Pants yawned and Twilight laid her down next to her, cuddling her gently. After a few seconds, Twilight fell asleep, still in her foal attire.

Meanwhile...

Princess Celestia was in her own bedchamber, looking at old photo albums full of pictures of her and Twilight when she was a filly, studying together. Those were good memories. Not only did they study together, they ate dinner together, laughed together, and spent so many good times together. There was even a time when Twilight had the munchies in the middle of the night, and while she was caught in the kitchen, trying to sneak some snacks, she fell face-first into a cake. Both her and Celestia howled with laughter, and enjoyed the cake. Celestia closed the last album and sighed.

"I remember all of those good times", she said, "Twilight and I lived together and had so much fun together. But, now she has finally found her destiny, and is now a princess. I'm proud of her, but I do miss those days. I wish she was more like a foal, so I could take care of her". Celestia facehoofed, knowing that she was talking to herself. Celestia stood up and went to see if Twilight was OK. She used her magic to unlock the door and open it. What she was was unexpected.

Twilight was sleeping soundly in her bed, wearing flannel pajamas, cuddling her doll, and suckling a pacifier. Celestia walked over to Twilight to see if she was wearing something else. She used her magic to unzip the pajamas a bit and saw Twilight's wet diaper. Celestia was very surprised, but couldn't help letting out a small 'aw'. Twilight looked so cute in her diaper and pajamas. And she was sleeping with her doll, which made her cuter. Celestia smiled. She had gotten her wish. Celestia changed Twilight's wet diaper, not wanting her to be cold and clammy down there. Then, she left the room, not wanting to disturb Twilight while she slept. However, when Twilight would wake up, she would ask Twilight a question that she would never forget.

~~~~~~~~~~

Twilight woke up with the cutest yawn ever heard. She smacked her lips and rubbed her eyes for a few seconds. Then, she looked at Smarty Pants and hugged her tightly, smiling.

"Good morning, Smarty Pants", she said, rubbing her mane.

"Morning, Twily", Smarty Pants said. Twilight gave her a small peck on her muzzle while she reached down to poke her wet diaper. But, when she poked her diaper, she felt nothing but soft, dry padding. Twilight raised her eyebrow, confused. She remembered wetting her diaper like the bottom of her hoof. Then, she began to get a frightening thought. What if someone came in and changed her diaper? What if someone had seen her secret fetish? Her train of thoughts were interrupted when she saw a golden aura form around the lock on the door. Twilight's pupils shrank to the size of needles as she buried herself in her covers, covering everything but her head. The door opened and Celestia walked in, smiling bright.

"Good morning, Twilight Sparkle", she said.

"M-morning, Princess Celestia", Twilight said, not wanting to show her nervousness.

"I take it that you slept well?"

"Like a foal". Twilight realized what she said, and it made her even more nervous.

"Well, breakfast is to be served in five minutes, so you may want to get ready".

"Understood, Princess".

"So, I see that you have a foal fetish". Twilight nearly had a heart attack.

"Wh-What? I-I don't have a-" Before Twilight could even finish, Celestia used her magic to uncover Twilight, exposing her pajamas.

"You were saying?", Celestia said, catching Twilight dead in her lie. Twilight felt tears of embarrassment come to her eyes. Her secret was exposed, to one of the most important mares in all of Equestria. "Twilight, are you OK?"

"Don't look at me!", Twilight said, burying herself back in the covers. Celestia sat down next to Twilight and uncovered her upper body. Twilight was crying, embarrassed heavily.

"Twilight, are you OK?",Celestia said again. Twilight only sniffled, not saying anything else. Celestia knew Twilight was very embarrassed. "Twilight, look at me". Twilight slowly looked at Celestia, her purple eyes pouring tears. "Why are you sad?"

"I'm ashamed!"

"Ashamed of what?"

"Myself!"

"Why? Because of your little fetish?"

"What do you think?!... your highness". Twilight had to add that last part, remembering that she was talking to a higher-class royal than her.

"Sweetie, why are you ashamed? This is what you like to. Did you think I was going to be disgusted?" Twilight nodded. "Well, I'm not. In fact, I saw you sleeping in that last night, and I changed your wet diaper, because I didn't want you to wake up cold and clammy".

"Really?"

"Yes. What did you think I was going to do? Send you back to Magic Kindergarten because of your little fetish?"

"That's exactly what I thought you were going to do".

"Well, first of all, I can't, because sending you there would be against the rules of royalty. Second of all, I would never send you there because of a fetish. By the way..." Celestia looked around, making sure her and Twilight were alone. "Both Luna and I had the same fetish".

"You did?"

"Yes. Right after we lost Mother and Father, we were very stressed out, and we used to act like foals, and that relieved high levels of stress".

"Wow. Princess Celestia and Princess Luna... both had a foal fetish".

"Yes. Now, there's something I have to ask you".

"What is it, Princess?"

"Since you have this fetish, would you mind if I treated you like my own?"

"You mean like... feed me, dress me, play with me, and... change me?" Twilight had to restrain her excitement while saying those last words.

"Yes. That is, if you would like that". Twilight didn't even hesitate to answer.

"I would, very much!" Celestia smiled.

"Great!"

"But... could you please call me 'Twily'? I love that name".

"Only if you call me 'Mommy'". Twilight nodded. "OK, Twily. Let's go. Breakfast is about to be served". Twilight gave Celestia puppy-dog eyes and a saddened lip. "What's wrong Twily?"

"Can Smarty Pants come too, Mommy? Please?"

"Of course she can". Celestia levitated Smarty Pants into Twilight's hooves. Twilight hugged her tightly. Celestia stood up and walked downstairs to the dining room, Twilight following.

Once the two alicorns reached the dining room, Twilight sat down in a seat and Celestia sat across from her, just in time for breakfast. The cooks served the two, and then left. Twilight smiled as she looked at her plate. Chocolate chip pancakes, sprinkled with diced hay, and topped with whipped cream, oats, and chocolate syrup, her fillyhood favorite. Twilight's stomach growled at the sight, and she wasn't about to just sit there and stare at them. She used her magic to raise her knife and fork, but before she could take a bite, she 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 to get owwies".

"But Mommy", Twilight whined, "I'm hungry!"

"I know you are", Celestia said, "So I'm going to feed you". Twilight had to strain to keep her excitement in.

Celestia cut Twilight's pancakes into little pieces while Twilight waited patiently, hugging Smarty Pants. After cutting Twilight's pancakes, Celestia used her magic to tuck Twilight's napkin in the collar of her pajamas. Celestia put a piece on the fork and held it out to Twilight. Twilight knew she wanted it, but decided to play a little. She made a disgusted face and turned her head. Celestia chuckled, catching Twilight's joke.

"Come on, Twily", Celestia said, poking Twilight's lips with the fork a few times, "You're not leaving this table until you finish your breakfast, so I suggest you eat up". Twilight reluctantly opened her mouth, taking the fork into her mouth. Twilight could taste the sweet pancake as she chewed and swallowed.

"Mmm", Twilight said, smacking her lips audibly. Celestia smiled.

"There we go", Celestia said, "Good girl". Celestia kept feeding Twilight and herself until both of their plates were clean. Twilight could feel her full tummy as she rubbed it. But, she could feel her throat a little dry also. She reached for her mug of coffee, but it was slid across the table over to Celestia.

"Babies can't have coffee", Celestia said, "If I were to give you coffee, you'd be very hyperactive". With only two gulps, Celestia completely downed Twilight's coffee, making the young alicorn look down with sadness. "Aww, Sweetie. Don't be sad. I have something else for you to drink". Twilight's frown soon turned into a smile. "But, we'll have to go upstairs first". Celestia walked upstairs, Twilight following.

Once the two got upstairs, they went into Celestia's bedchamber. Celestia smiled as she laid down on her side on her big purple rug she uses as a bed. Twilight walked over to her and sat down next to her.

"So?", Twilight said, "What is it?"

"Well", Celestia said, "It's inside me, and you'll have to suck it out".

"Suck it out? What do you mean?" Twilight looked at Celestia's two pink nipples, and then back into her eyes. "You mean...?"

"Yes. It's good for a baby to nurse from its mother".

"I... I don't know..."

"You know you want to. I can sense your anticipation".

"Well... yeah, but it doesn't feel right, and what if I accidentally hurt you?"

"Sweetie, you won't hurt me by simply suckling from me, and besides, I'm your mother, remember?"

"Yes". Twilight felt her throat starting to become sore from dryness, and the nursing sounded more and more tempting. And to Twilight, milk was a lot more appealing than coffee. Twilight could feel her mouth starting to go dry as she became more and more thirsty, and she finally decided to do it. "OK, I'll do it, but please don't tell anypony else! Not even Princess Luna or Cadence!"

"I won't, Sweetie. Our little secret".

Twilight looked at Celestia's mounds again. Though she was excited, she still felt a little uneasy. She laid down on her stomach, her muzzle about an inch away from a teat. Twilight gulped, starting to feel very uneasy. She gave the teat a small lick, making Celestia shiver a bit. Twilight didn't taste anything bad or didn't get any hair in her mouth, so she became more comfortable. She wrapped her lips around the nipple, comforting her mouth before getting a small squirt of milk, which instantly touched her tongue. She took a few seconds to let the milk marinate with her taste buds.

She couldn't believe it. She LOVED the taste. It was sweet, warm, and creamy. Even though it was a little heavy in viscosity, she still loved it. She began to pick up her pace, suckling a normal stream of milk from Celestia. Celestia smiled as she felt Twilight's suckling and her milk exiting her and into Twilight's mouth.

"That's it, Twily", Celestia said, rubbing her back, "Drink up. You're gonna be so big and strong". Celestia continued to coo at Twilight as Twilight continued to suckle.

Soon, Twilight had suckled Celestia dry. She pulled away, milk dripping from her chin. Her tummy was seriously full. Even fuller than it was after her pancakes.

"There we go", Celestia said, sitting up, "Did my little filly get enough?" Twilight nodded. "OK. If she gets hungry again, she can have more once Mommy's milk comes back".

"I think that'll be a while", Twilight said, "My tummy is full to the top".

"Great. Now, Mommy has to go to court for a few hours". Twilight shot Celestia with the cutest puppy-dog eyes she'd ever seen. "Aww, does somepony not want Mommy to leave?" Twilight nodded. "Well, don't worry. Today's Saturday, and on Saturdays, court only lasts two hours instead of six. I'll be back in no time". Celestia stood up. "In the meantime, would Twily like to play with some toys?"

"Toys? I didn't bring any-" Celestia placed her hoof over Twilight's mouth before she could finish.

"You didn't have to, because I've got some for you to play with". Celestia walked over to her closet and took out several dolls and blocks and laid them out on the rug. Twilight smiled as she looked at the tiny mountain of toys in front of her. "Now, play nice with those. They were given to me by my mother". Twilight nodded and began playing. "I'll see you in two hours". Celestia kissed Twilight's cheek and went to court.

~~~~~~~~~~

Once Celestia's court ended, she went back upstairs to check on Twilight. She walked into her bedchamber and smiled as she saw Twilight still playing.

"I'm back, Twily", she said, "Would you like Mommy to-?" She was cut off when a very foul odor struck her muzzle. She held her muzzle and saw the back of Twilight's pajamas bulging out a little. "Twily?" Twilight looked at Celestia.

"Yes, Mommy?", she said.

"Do you have a poopy diaper?", Celestia asked. Twilight blushed, deciding to play a bit.

"No, Mommy", she said, smiling.

"Then what smells so stinky?"

"I don't smell a stinky".

"Come on Twily. I know you made a poopy".

"Uh-uh".

"Don't lie to me, Twily, unless you would like the whole city of Canterlot to know about your fetish?" Even though Twilight knew she was joking, she decided to fess up.

"I made a big, stinky poo-poo in my diapee!", she said in her best foalish voice. Celestia smiled.

"OK", she said, "Thank you for telling the truth, Now, let's go get you changed".

A few minutes later, Twilight was changed and smelled good again. Celestia carried Twilight back into her bedchamber and sat her back down on the rug. Twilight yawned loudly, feeling the need for a nap. Celestia smiled as she rubbed Twilight's mane.

"Is little Twily getting sleepy?", she said. Twilight looked at Celestia, fluttering her eyes. Even though she was sleepy, Twilight still wanted to pretend she wasn't before her nap.

"No, Mommy", Twilight said, "Me not tired". Celestia chuckled, getting Twilight's joke again.

"Are you sure?", she said. Twilight nodded. "Well then, you won't feel sleepy once I put this blankie over you?" Celestia levitated a big yellow comforter over Twilight. It was think and soft, and feeling it made Twilight more sleepy. She laid down on her stomach, still fighting the sleepiness.

"Nope", she said, her voice starting to become weaker, "I'm still... not... sleepy". Celestia smiled.

"Well, will you be if I let Smarty Pants lay with you?" Celestia levitated Smarty Pants over to Twilight and her down next to Twilight. Twilight couldn't help but grab Smarty Pants and cuddle her. Feeling the soft doll's touch, Twilight felt even more sleepy. She yawned again, having trouble keeping her eyes open. Twilight resisted the urge to get comfortable and continued to fight.

"Is that all... *yawn*... you got?" Celestia then levitated her biggest pillow over to Twilight and placed it under her head. Twilight could feel the soft, smooth pillow touching her face, and every second that passed made her even more sleepy. She was able to use the last of her strength to keep herself awake. "Still... not... sleepy". Celestia saw that Twilight was fighting tough, so she decided to bust out her secret weapon... that she had gotten from Fluttershy.

"If you're not sleepy", Celestia said, "Then you would be able to stay awake while I sing a little lullaby?"

"Lullaby?", Twilight said.

"Yes, and I'm sure you're familiar with it".

Celestia sat down next to Twilight and started singing "Hush Now, Quiet Now" softly into Twilight's ear, while rubbing the purple alicorn's back. That song was very strong to the ears of Twilight, she yawned again. Twilight couldn't keep her eyes open anymore, and she was completely comfortable at that point. She could feel her bladder releasing itself into her diaper from the relaxation, but she didn't mind. Twilight threw in the towel and went to asleep, sighing loudly. Celestia smiled as she kissed Twilight's muzzle and covered her up a little better.

"Sweet dreams, Twily", Celestia said. She even gave Smarty Pants a little kiss, knowing Twilight would like it. After that, she sat down next to Twilight and began to do some of her paperwork. However, while doing them, she kept thinking about Twilight's fetish. She wondered if Twilight would get bored of just having a mother to take care of her. What if Twilight wanted something else?

What if she wanted... a playmate?
