Three Princesses and a Twily
By Scribe Feather

	Evening fell upon Equestria as the sun started to set in the night sky. Hues of orange and reds replaced the daytime's blues, marking the end of the work day. A cool breeze brushed through the sky, gently nudging the summer heat away. 

	Canterlot was slowly making it's transition to it's lively night life when a carriage pulled by two royal guard ponies came rolling down the main streets of the city. The sole passenger, Twilight Sparkle, was never one to travel in such an over-the-top manner, but her fellow princesses were insistent. She was even expected to wear her normal princess garb to keep up the image. At least the long ride to Canterlot Castle gave the alicorn time to lean back and relax.

	Twilight was, to say the very least, exhausted. Her new duties as a princess had sapped the young pony of her energy and easily tired her out.

	Lucky for the purple alicorn, the Princess Conference was today and that meant she'd finally find time to relax. She smiled to herself at the thought of what was to come.

	On the surface, the conference was a monthly gathering of the four princesses. It was masqueraded as an important discussion among the royalty to plan and negotiate and strategize. But in reality it was an opportunity for Twilight to de-stress and forget about the heavy burden of princesshood, even if it was just for a day.

	Twilight was rather excited when the other three princesses said they wanted to take care of her like a foal. She was told it was the 'most efficient way to get rid of stress', plus they all seemed eager to do it. It was a strange way to de-stress, but Twilight quickly found it to be exactly what she needed. The regression did wonders for her mind and allowed all the princess stress to just melt away.

	Canterlot Castle soon came into view, steadily getting bigger as the carriage rolled away. It's white color seemed to change with the sunlight as the reds and oranges reflected off the many towers and spires of the grand structure. It's moat reflected the sunlight like a shimmering mirror.
	
	The carriage pulled up to the castle's main entrance, slowing down gently before the ponies stopped completely. Two guards waited by the main doors, saluting Twilight when she arrived.

	Twilight climbed out of the carriage and readjusted her princess dress. "Thank you sirs,"  she said as she bowed her head towards the carriage pullers. The two white ponies in golden armor bowed their heads back before pulling the carriage away. Their services were concluded for the day.

	The purple pony's natural curiosity couldn't help but guess where the two guard ponies would be off to after they ended their shift back at the barracks. Perhaps a quiet dinner with their family or a romantic evening in Cloudsdale with their significant other. It was tough to really guess what all these guards did off duty. Whatever it was, it was surely not as unusual as what Twilight was up for.

	Twilight entered through the main doors of the white castle, passing pairs of guard ponies here and there who saluted her as she passed. Princess Celestia was the first princess to greet her at the foot of the large, main steps. The white alicorn stood with grace and princess like poise. She smiled when Twilight came close. "Good day, Princess Twilight," She gave the purple pony a graceful bow of respect.

	"Good day to you too, Princess Celestia," Twilight returned the bow before the two walked up the main steps. The sound of their hooves clopping loudly against the marble steps bounced off of the tall walls that surrounded the room. Twilight adapted her stride to better fit the prim and proper reputation that princesses had. She had to behave like a princess while she walked alongside her fellow princess. 

	"We are please you could make it. The other princesses are waiting for us in the conference room," Celestia calming replied as they reached the head of the steps.

	"After you, Princess," Twilight respectively bowed her head and allowed the white pony to walk ahead.

	The two turned and walked down the hallway to their left. A long red carpet stretched down the length of the quiet hall, quieting their hoofsteps, but still echoing as the moved down it's length.

	The 'conference room', as the new gold sign on the outside of the door called it, was a room that at one point was just an empty room that was left neglected over the years. No pony ever used it, so the doors remained closed, leaving the room to gather dust. At the genesis of this Princess Conference idea, the castle's work hands went right to work, cleaning the area up to better suit the royal ponies.

	The Princesses' requests for the room were rather simple: A big open gathering area where they could bring in whatever they needed for the conference as well as a small connected bathroom with a bath. They also requested a small kitchen area where they could store and cook food. Nothing Equestria's finest builders could create and the finest artisans to decorate.

	Upon entering, Twilight found that the room had a collection of large, discrete crates that sat in neat stacks to one side. Other then that, the room was rather barren for now. It was nothing but carpeted empty space, save for a small tea table with four cushions surrounding it.

	Luna and Cadence were already there when Twilight had arrived, sitting by the small table with tea cups floating in the air. The two princesses gracefully raised their heads towards the purple pony and smiled.

	"Greetings fair Princess Twilight," Luna said rather theatrically as the group joined together around the table.

	"Salutations, Princess Luna. Princess Cadance," Twilight bowed her head to each princess respectively, wearing a regal and polite smile on her face.

	The group stood there for a moment in silence, each having that royal smile as they looked at each other. Twilight was the first to break, grinning widely before she giggled out loud. The three other ponies looked at each other before laughing as well.

	"'Salutations'?" Princess Cadence said with a laugh.

	"What? Lot's of ponies still use that word!" Twilight answered back with a big smile.

	"Not as many as you'd think," Celestia added as she magically locked the main doors. "Shall we get started?"

	Twilight couldn't smile any bigger as she nodded with excitement.

	"Alright alright. Into the bath then," Celestia ushered the excited purple pony out of the room and into the connected bathroom. "Luna and Cadence have quite a bit of work to do."

	The bathroom was quaint by Canterlot standards, containing a single toilet, sink, and a comfortable looking bathtub. The softest of white towels hung on a rack beside the tub as a selection of shampoos and bubble bath lined the back wall.

	Celestia turned on the bath water, running a hoof under it to insure the optimal temperature. She ran it for a few more seconds before plugging the drain with a rubber stopper. Twilight waited patiently, doing her best not to hop up and down as Celestia prepared the bath. 

	As the water filled up the tub, Celestia took it upon herself to undress Twilight. Twilight tried her best to help, but every twist she tried to make to ease the task seemed to just complicate things. Celestia did well enough without her help and didn't ask for any assistance as her princess dress was taken off, piece by piece. A series of hangers floated in the air, each taking on a piece of Twilight's dress before being hung up on a nearby rack.

	A bottle of flower scented bubble bath came floating from the cabinet as Celestia poured a bit into the water. Bubbles started to fill the tub as Twilight squeaked with excitement. Celestia was quick to notice as she turned off the water, "somepony excited for her bath?" Twilight nodded happily before quickly jumping into the water, splashing the water everywhere, including Celestia who got hit by the bulk of the splash. Celestia sighed heavy as she floated a towel off the rack and dried herself off.

	"Oops...Sorry," Twilight flinched before slowly sitting down in the tub. She patiently waited for Celestia to dry herself off and made no attempt at washing herself.

	"It's alright...Quite frankly I should have seen it coming," Celestia said as she finished drying herself off, using the same towel to soak up the puddles that gathered outside the tub. "So we're not here all night, could you save all the splashing for my sister?"

	Twilight blushed shyly and nodded, "O-okay...Sorry."

	And with that, Celestia nodded and proceeded to bathe the purple alicorn. She used a clean washcloth to get in the hard to reach parts including Twilight's back, behind her ears, and the hinges of her wings. Twilight loosened up under Celestia's touch, drooping a bit in the flower scented water as she was cleaned up well. She wore a soft, regressed smile on her face, feeling so pampered. Already she could feel the princess stress melt away.

	Slowly, the white pony worked her way from head to toe, cleaning Twilight up well, leaving a pleasant flowery scent behind. She seemed to slow down when she reached Twilight's waist where the purple pony got noticeably tenser. Celestia grinned as she slowly got closer to Twilight's sex, hearing the purple pony pant heavily at the teasing.

	Twilight silently begged for Celestia to continue. She could just about feel the wash cloth near her pussy. She even went as far to lean towards the invading hoof, but every attempt would be casually avoided by the white pony.

	After teasing the regressing pony quite a bit with near hits, Celestia floated a small cup into the scene and began shampooing Twilight's mane. The shampoo had a much stronger and much more infantile smelling scent to it. The smell filled Twilight's nose as she shut her eyes while Celestia scrubbed the shampoo into the mane. Celestia gently washed out the shampoo with a couple cupfuls of water, before she deemed the bath complete.

	Celestia stood up from her spot next to the tub and grabbed another fluffy towel. She opened up the sheet of absorbent fabric for Twilight. "Climb on out, silly filly."

	Twilight climbed out of the bubbly water, much more carefully this time. She tried her hardest not to splash her caretaker before being wrapped up in the soft towel. Celestia dried the pony off well, not letting her help even once.

	A brush as well as a couple pink bows floated from the cabinet as Twilight finished drying. Celestia slowly brushed Twilight's drying mane, neatening it up. Celestia tied Twilight's mane into pigtails, giving her a youthful appearance. Twilight smiled big at her reflection now, it was such a big difference and she loved it!

	"There! There's the little Twily!" Celestia chirped happy as she looked at Twilight's reflection. A true example of an adult foal and she felt like it too save for the warm heat growing between her legs.

	When the two returned to the conference room proper, nursery furnishings were already being magically set up around the room. Cadence and Luna were just finishing up the place, carefully setting each item in a set and organized location. A changing table sat against the right wall, complete with it's fresh stock of diapers, wipes, and a pink diaper pail resting beside it. Luna could be seen neatening up a lovely crib with starry night sheets that sat on the left wall, but close enough to the window to allow moonlight to shine on the sheets. A large high chair fit for a full grown pony was being assembled next to the kitchen area by Cadence. After only a short bath, the room quickly took the form of an adult nursery.

	Twilight was awestruck by the sight. Her eyes were wide open as she scanned the room. All those bright colors and infantile furnishings. It was enough to make any princess feel like she regressed into a little foal.

	"Staring at it isn't going to get you padded up, foal," Celestia broke Twilight's staring with a firm nudge to her side. "Go on!"

	Twilight didn't need to be told twice before she was dashing over to the large changing table. She turned to the other ponies with a happy bouncing and smile on her face.

	Celestia chuckled at the eager adult foal and lifted the purple pony up with her magic. Twilight was gently placed on top of the padded changing table, positioned on her back and ready to be changed.

	A fluffy pink diaper was pulled out from the shelves underneath the changing pad as well as foal powder. Twilight's legs were gently lifted up and the soft diaper slipped underneath effortlessly. Celestia gave Twilight's diaper area a liberal amount of powder and even sprinkled some onto her chest to spread the infantile scent. The powder helped remind Twilight that she was being a big foal today as well as turn her on just a little bit more.

	Twilight giggled with a big smile as she couldn't help but wiggle with excitement as the diaper was slowly pulled up between her legs, taped securely around her waist. She was now enveloped in the wonderful, plush garment and was ready for bed.

	"There we go! All set for the night!" Celestia concluded the diaper change by putting away the powder and picking Twilight back up.

	With little resistance from the her, Twilight was carried over to the crib and deposited inside. She quickly snuggled under the soft baby blankets that covered the plastic mattress, getting nice and warm for her sleep.

	Celestia lovingly tucked her in, making sure no limbs stuck out from under the layers of baby blankets. A pink pacifier was floated down to Twilight and slipped into her mouth which gladly accepted it. "Sweet dreams, little princess," Celestia commented softly, kissing Twilight's forehead before raising the crib's side.

	Celestia left the room shortly after turning off the main light with Cadence following behind. It was past Celestia's bedtime as well and she needed to be up early to raise the sun. She closed the door behind her ever so gently, leaving the room cloaked in a soft blue light from the nearby night light.

	Twilight felt safe and secure inside the crib, regressing into a pleasant mindset as she stared up at the star themed mobile that hung over head. She smiled behind the pacifier as she lazily suckled on it's rubber nipple. She quietly watched the mobile gently spin above her, slowly falling under it's sleepy spell until she was fast asleep.

	With the pony slumbering soundly in her crib, Luna's horn began to glow in the dark room. Her magic slowly worked it's way into Twilight's dreamscape, helping the pony reach a natural level of regression.
✶✶✶✶✶
	Twilight found herself floating in pitch blackness. She couldn't remember how she got there or why she was floating there in the first place. Her mind simple dealt with it as her body floated in the empty voice with no real direction or reason.

	"Twily," a voice slowly came into focus as the darkness slowly started to fade. "Twily, wakey wakey..."

	Twilight started to open her eyes and was instantly greeted with the shining faces of all her pony friends. The four other ponies stared at her as she slowly woke up from a nap she didn't remember having. 

	She looked around for a moment and found that they were all in the Ponyville library and she was being totted around in a stroller for some unknown reason. Everything around her seemed brighter and more vibrant.

	"Good morning, Twily," Fluttershy said with a smile as she looked down at the much smaller pony.

	"Ya dozed off fer a moment there," Applejack added with a little smile.

	"She's up!?" Pinkie Pie bounced into the picture with a big smile. "Let me see! Let me see!"

	"P-pinkie, easy!" Applejack chimed in, "she just woke up!"

	With that said, the rest of the group gave the foal some room. The purple pony took a moment to look at herself. She looked over her smaller body and the diaper that seemed to shrink with her.

	Twilight Sparkle then caught a glimpse of her reflection in a nearby mirror. It was her, but a much younger version of her. She was a foal and a thick diaper butt to prove it! She smiled at this realization and started to wiggle in her seat.

	"Lookit! She's looking at herself through the mirror!" Pinkie giggled as she bounced in place.

	"Well then absolutely LOVE looking at herself after we get her dressed in THIS!" Rarity crooned over a pink dress that she floated over from a hanger.

	Twilight was floated out of her stroller seat and magically dressed up in this new dress. Rarity gently manipulated her foal limbs through the holes of fabric. The material was a bit itchy to her oddly sensitive foal coat and was rather extravagant for foal wear. 

	"Oh don't you look ADORABLE!" Rarity smiled behind Twilight as she posed the foal in front of the mirror. Twilight felt like she was on a runway, showing off the latest fashion as everypony gawked at her new clothes.

	The dress didn't seem to cover her diapered rump at all. In fact, it seemed to amplify it. One might say it was purposely like that to make the foal appear cuter, but it could have very likely just been a way to make diaper checks easier.

	"Rarity, you can't have her wear that!" Rainbow Dash commented, hovering over the floating foal who was being posed in front of the mirror.

	"Because it's too froufrou?" Rarity assumed as she adjusted an uneven hem of the dress.

	"Because it's got more layers then Pinkie's birthday cake!" Rainbow Dash looked over the pink and white dress with it's many layers. "She'll get too hot!"

	Rarity thought the feedback over as she looked at Twilight from different angles. "Perhaps you're right. I'll have to make a few adjustments,"

	Twilight was undressed as quickly as she was put into the thing. Piece by piece, Rarity started to undress the pony in front of her friends. They didn't normally wear clothes, but somehow being stripped down to nothing but her diaper made Twilight feel exposed and small. She curled her limbs up close to her body in shyness. A normal foal would probably find nothing wrong with floating in front of friends with a diaper on, but Twilight couldn't help but blush a little bit as she was slowly floated down to the floor once again.

	Her foal hooves wobbled underneath her weight for a moment before the limbs buckled causing her to plop down onto her diapered rump. She dropped to the ground with her diaper absorbing most of the impact. She barely felt any of it.

	Her friends looked at her for a moment, likely expecting her to cry from the shock alone. But the regressed foal simply smiled up at them as they sighed with relief.

	Rarity went off to a corner of the room with a pair of scissors and cuts of fabric floating around her head. The diligent pony would likely have a new, 'updated' dress for Twilight to try out soon.

	A collection of toys caught Twilight's eyes. Wooden blocks and colorful rattles laid scattered across the floor. She crawled closer to the epicenter of all the fun looking toys before plopping her diapered rump on the play mat. 

	Pinkie Pie joined in as a playmate, laying down next to Twilight in an excited thud as she dropped to the floor. At first, Pinkie tried to entertain the little foal by introducing new games using the toys that she had scattered around her. However, the more fun games the pink party pony came up with on the fly, the less she paid attention to her and more to the toys.

	Twilight's body didn't portray it, but inwardly she rolled her eyes at her easily distracted friend. Just Pinkie being Pinkie. Twilight's eyes locked onto a familiar doll, her childhood toy, Smarty Pants whom she quick grabbed and cuddled. The group of spectating ponies 'awwed' at the sight.

	"She'll be gettin' hungry soon," Applejack suggested.

	"Uhm, Dash? Could you keep an eye on her while I fix her bottle," Fluttershy asked softly to the other pegasus.

	"Me? Why can't Pinkie Pie do it? She LOVES babies!"

	"Yes, that's true...But Pinkie's..." Fluttershy trailed off as she glanced over at the pink earth pony who was found laying on the ground next to Twilight. She was playing with the pile of wooden blocks, paying little attention to the purple alicorn who cuddled her doll. "Pinkie's Pinkie."

	"Alright, fine!" Dash dropped down from the air and seated herself close to Twilight.

	Twilight noticed Dash's disapproval of the task and looked around for a way to cheer the pony up. She grabbed a nearby rattle and held it up to Rainbow Dash, smiling behind her pacifier.

	A small smirk managed to sneak it's way to Dash's face. "Well I guess you're kinda cute...For a foal," Rainbow Dash picked up the rattle and started to shake it a couple times. Twilight seemed to like that, clapping her hooves and giggling.

	"Having fun?" Applejack's voice chimed in as Rainbow Dash looked in her direction.

	"I'm just playing with the baby!"

	"Well, it's time for the baby to have her bottle," Applejack smirked at the pegasus, "unless you want to play alone."

	"I was just playing to keep HER happy! Geez!" Rainbow Dash rolled her eyes at the teasing and stood back up.

	With no use of fancy magic, Applejack gently lifted Twilight up from her play mat and carried her over to a pile of cushions. She gently laid herself down, placing Twilight in her lap before replacing Twilight's pacifier with the warm bottle.

	Twilight quickly latched onto the bottle, sucking down the milk as quickly as the rubber nipple allowed. The liquid filled her foal tummy up with it's soothing warmth, making her smile lazily behind the bottle. She even slipped into a daze for a moment or two. She snapped back to reality when she saw Applejack pulling out a book from the corner of her eye.

	"This was my favorite story when I was a filly," Applejack smiled down at the foal who suckled down the warm milk.

	Twilight looked at the book cover and tried her hardest to remember what it was. Her memory was fuzzy and the book didn't seem all too familiar. The title was blurry for some reason and the only thing that could be made out was a happy pony trotting through a green forest.

	Applejack picked up on Twilight's curiosity and opened the book to it's first page. Twilight couldn't make out the scribble like words that littered the page. She did however enjoy colorful pictures that accompanied each paragraph.

	Applejack's voice seemed muffled, but somehow the magic of the story spun around Twilight as she became engrossed in the wonderful adventure.

	Picture by picture, the story seemed to become white noise as Twilight paid less and less attention towards it. Twilight found herself dozing off once again. She felt safe and secure without a care in the world. The bottle was replaced by her hoof at some point which she suckled as she slowly fell asleep once again.
✶✶✶✶✶
	Twilight was suddenly woken up by the sunlight. She opened her eyes wider and wider before letting out a big yawn. She looked around and remembered that she was still in the crib from the night before. Slowly facts of yesterday came crawling back to the sleepy pony. She smiled warmly as she stretched all her limbs up into the air, the memories bringing pleasant feelings to her body. 

	As she moved, she noticed a warm squish coming from between her legs. Craning her neck, Twilight found that she had wet in her sleep and her diaper didn't leak, not even once. She gave her swollen, wet diaper a couple testing pokes. The padding squished and morphed a little bit under her touch, sending shivers down her spine. The pony happily squirmed in place, reveling in the wonderful sensations that filled her body to the peak.

	Twilight was just about to enjoy the feelings fully, floating a hoof down to her squishy diaper front before a voice interrupted her play. "Morning sweetheart!" Cadence looked down at the diapered pony with a warm, motherly smile.

	Twilight snapped her naughty hoof away from the swollen diaper and smiled big up at the other princess. "Morning!"

	"Sleep well?" Cadence asked, eyeing Twilight's well used diaper with a hungry gaze.

	"Mhmm," Twilight let out another yawn and stretched her legs again.

	Cadence lowered the crib gate and smiled at the diapered pony. "That's good to hear. How's your diaper?" Before Twilight could answer, Cadence was already doing a thorough job of checking the swollen yellow diaper. She gave it a good couple squeezes, pressing it firmly against Twilight's body. It was obviously a way of teasing the aroused pony little by little, but Cadence carried on her way as if it was absolutely normal. "Just as I thought. You're absolutely soaked, sweetheart!"

	Twilight panted a little, holding back a whimper when Cadence finally pulled her teasing hoof away. Her wings felt stiff underneath her as she was pulled out of the crib once again by the glow of magic.

	As she floated over to the changing table once again, Twilight noticed how much her soaked diaper sagged between her legs. Her wings stiffened a little bit more as she reminded herself that she wet herself. 

	Once on her back, Twilight's diaper was slowly opened up, tape by tape. Cadence continued with the change as slowly as possible, tensing the other pony up with sexual tension. The diaper finally opened, letting a cool breeze brush against Twilight's heated pussy, causing her to shiver.

	The diaper change proceeded as usual. Cadence wiped Twilight clean of urine, spending a little too long around her crotch. The wipes were gathered in the old diaper and the rolled up ball of urine was tossed into the diaper pail. The old diaper was quickly replaced with a new one complete with its own powdering and subtle teasing. Cadence looked over her work, testing the leg gathers to ensure a tight fit.

	"Now let's get the little princess some num nums!" Cadence said, officially concluding the diaper change.

	Twilight was once again lifted off of the changing table, this time carried over to the blue highchair that waited in the kitchen area. She was gently placed in the white, plastic seat before the metal tray was slid into place. The tray allowed enough room underneath it for her to move her hooves over it and beneath it freely, but it'd take a lot of effort for her to slip out from the childish seat.

	"Oh! But where's my head! I need to get somepony her bibby!" Cadence smiled, giving Twilight's nose a little boop. She turned around and left the pony in her highchair.

	Now with a moment to herself, Twilight's crisp diaper started to beckon her. A hoof slid under the high chair's metal tray and rested on top of the white diaper. The powdery scent sent shivers down the purple pony's spine, making her gasp a tiny bit. She continued to rub a hoof into the padding, biting her lip to quiet any moans that slipped through her muzzle. She knew she shouldn't be doing this and was being a naughty little princess for rubbing. Her eyes slowly started to close as she teased herself further and with stronger rubbings.

	Her hoof quickly shot back down to her side when she felt a bib being floated from behind, she didn't want to be caught being naughty...Not yet at least. The soft, blue colored bib magically slipped around her neck before Cadence knotted it loosely.

	"Now we won't be getting any messies on ourselves!" Cadence cooed when she finished the job. The pink pony pulled a chair up next to the diapered pony, before walking off to the small kitchen area that hugged the south wall.

	Cadence hummed a happy tune to herself as she prepared Twilight's meal of oatmeal. Her back turned towards the diapered pony as she hovered around the oven, boiling some water and mixing in the tasty oats into a small plastic bowl.

	As Cadence worked hard at assembling the simple ingredients of today's breakfast, Twilight slowly reverted back to what she was doing before. Her hoof returned to the front of her diaper, her ears wiggling at the pleasant sounds of the crinkling padding. "M-mph," was all the pony said as her eyes closed once again. Her rubbings dug deeper into the crisp padding as her arousal built up higher and higher.

	Suddenly her rubbings were abruptly interrupted by the sound of a plastic dish being dropped on the tray in front of her. She quickly stopped rubbing and opened her eyes. Cadence was seating herself next to the high chair. Was she watching? How long had she been watching?

	Cadence smirked up at the diapered pony before levitating a plastic spoon into the mushy oatmeal. She knew, somehow Twilight knew she interrupted her before she could finish. "Open wide, sweetheart," Cadence floated a spoonful of oatmeal in front of Twilight.

	Twilight pouted a bit as she reluctantly accepted the oatmeal. Cadence could have given her just a little bit more time to finish. Just a few more minutes and Twilight would have been satisfied.

	Regardless of what she pouted about, Twilight still ate every mouthful of oatmeal that she was given, finding that she enjoyed the little bits of apple that were mixed into the oats. Every now and then Cadence would 'accidentally' miss Twilight's mouth, getting oatmeal on her chin, cheek, or even dribbling some down her bib and onto her exposed diaper.

	Much to her excitement, the oatmeal was moving things along inside, reminding her of her need to use the bathroom. In normal circumstances, Twilight would excuse herself and use the bathroom like a big pony, but this time wasn't normal circumstances.

	As Cadence scooped up another spoonful of oatmeal, Twilight began to push, wearing a far off look in her eye.

	Cadence was quick to notice, keeping the oatmeal floating in front of the diapered pony. "What's the matter, sweetheart?" Cadence played dumb as the diapered pony continued to push with her eyes slammed shut.

	Twilight grunted loudly, leaning forward in her seat as she gripped the high chair's tray. Her face strained for a moment as her bowels began to push. Her rump raised a bit from the chair as her diaper began to bulge with her new mess. She loudly grunted as her face became red. Her bladder even decided to join in, hissing ever so faintly as it warmed up her diaper. Cadence waited patiently for her to finish.

	Twilight finally let out a sigh of relief, plopping back down in her seat with a satisfied grin on her face. She was quite happy with herself.

	Cadence pretended not to notice and simply continued feeding Twilight the rest of the sweet tasting oatmeal. She kept this up, spoonful by spoonful till the bowl was empty and Twilight was full with only minor damage done to the big. Twilight leaned back in her highchair, feeling as full as her diaper.

	Cadence loudly sniffed the air in front of Twilight and then looked at the diapered pony with a knowing look, "what's that I smell?!" Twilight giggled as her cheeks flared up. She simply shook her head in playful denial as Cadence continued to look at her with a raised eyebrow. "Are you hiiiiiding something, sweetheart?" Again, Twilight shook her head and giggled.

	The high chair's tray was pulled out, exposing Twilight's well used diaper. Cadence lifted Twilight up out of her seat with her magic and playfully floated her in the air. The purple alicorn giggled loudly as she was moved this way and that, her brown seated diaper swaying from left to right.

	The floating alicorn was turned around and Cadence gave her diapered rump an old fashioned sniff test. Her nose was mere inches away from the well used padding as she sniffed loudly and theatrically. She pulled her head away from the offending odor in an exaggerated manner. "Phew! What a stinky little foal!" Cadence chuckled as she held her nose with a hoof, floating Twilight away from the high chair.

	Twilight was effortlessly carried over to the changing table once more. With careful control, her body was laid on top, sitting squarely on bulging mess in her diaper. The pony yelped at the squishy sensation before being gently nudged to her back in the changing position.

	The purple pony giggled like a foal as her legs wiggled in the air above her. Filling her diapers was one of the most infantile things the princess could do and it made her feel more regressed than before. A pleasant fluttering filled her body as heat returned to her crotch. The smaller and cuter she felt, the more turned on she became.

	Cadence didn't say anything about Twilight's rising arousal and merely stilled the excited pony with a hoof on her tummy. With a glow of her horn, the princess floated a new diaper, wipes, and powder up from the bottom shelves, keeping them suspended in midair as she began the diaper change.

	First, the diaper was untaped. Each tape was removed slowly to further tease the diapered pony with anticipation. Her panting became shallower and shallower as the change progressed. Once free of it's four tapes, the yellow front of the diaper fell open on the changing table between Twilight's legs, releasing the strong odor that was being moderately held back by the garment.

	"Phew! Stinky stinky!" Cadence teased the other pony who blushed and giggled. Scented wipes were floated one by one down between Twilight's legs. Cadence placed each wipe inside the dirty diaper, making a small pile.

	Twilight twitched and 'mmphed' quietly each time a wipe found it's way too close to her hot pussy. She bit her lip as the cleaning continued, silently begging for Cadence to hurry up.

	Cadence noticed how aroused Twilight had quickly become as she replaced the smelly diaper with a crisp, white one. "Now we're nice and clean!" Cadence chirped happily with a little flutter of her wings. She slowly ran a hoof down the length of Twilight's body. The hoof slowed down once it reached Twilight's more sensitive lower half. "...And ready for the fun part."

	Twilight shivered on top of the padded changing table as Cadence's hoof brushed across her heated marehood. Her hoof brushed across it a second time and then a third until it started to rub against her. Twilight was quick to respond, panting heavily and watching Cadence tease her with hungry eyes.

	Cadence leaned her head down to Twilight's crotch, her tongue running down the length of her pussy. Her moist marehood became wetter with spit as Cadence pushed her closer to the orgasm she so craved. Cadence soon moved onto licking her clit which sent strong bolts of arousal down Twilight's spine.

	The purple pony moaned and squirmed on top of the table. Her hooves pressed deeply into the padding beneath her as her hips seemed to float closer to Cadence's muzzle. She was getting close, and Cadence could sense it.

	With one swift motion, Cadence quickly pulled her muzzle away from the moist marehood and pulled the fresh diaper up against it. She pressed the thick, crinkly padding against Twilight who moaned loudly now. She rubbed the dripping pussy through the diaper, moving steadily faster and faster.

	"M-mph! Ah!" Twilight exclaimed loudly as her limbs stiffened. Her diaper was still held close to her moist sex by Cadence, sucking up her aroused juices.

	"Such a big girl!" Cadence cooed as she waited for Twilight to ride out her orgasm.

	Twilight laid there in a daze, lazily staring up at the ceiling with a big goofy smile on her face. Her mind snapped back to reality when she felt the diaper being taped around her waist. "B-but I gotta go home today!"

	Cadence ignored her and finished changing her. Twilight merely watched as she was powdered and the diaper was pulled back up between her legs. She taped it securely around her waist, ensuring a leak free fit. "Now, I don't want you to take that diaper off till it's good and used, alright sweetheart?"

	Twilight blushed deeply, but nodded. She didn't want to disappoint her foalsitter, even if it required the risk of having her diapers discovered.

	The purple pony was lifted off the changing table once more and brought back on her feet. Her hooves wobbled for a few moments as they tried to remember their strength while coping with the extra thick padding taped securely around her waist.

	Cadence retrieved Twilight's dress from the bathroom and started redressing the other princess. She watched through a mirror as Cadence dressed her up with little help from her. Piece by piece, the dress was reassembled around Twilight. The flowing layers of the regal fabric hid the thick diaper well and made her look less like a diapered foal and more like a princess of royalty. Finally, the bows in her hair were removed, suddenly making her appear older.

	"There we go!" Cadence concluded, floating the now empty hangers over to the crib.

	Twilight smiled at her reflection, "thank you for the wonderful time!" She turned around and gave Cadence a big hug. 

	Cadence gladly returned it, embracing the diapered princess with a warm smile. "We enjoy having you here."

	Their hug was broken when there was a knock at the door. The magical locks clicked before the door slowly opened. Luna and Celestia peeked their heads in as they both smiled softly at the dress wearing Twilight.

	"Come to see me out?" Twilight asked as the two princesses walked in.

	"We wanted to say goodbye before you left." Luna said as Celestia closed the door once again.

	"And clean up your nursery before the maids came in." Celestia added.

	Twilight waddled up to the two princesses and gave them a big hug as well. "Thank you guys so much!"

	Luna was caught a bit off guard by the sudden hug, but leaned into it. Celestia smiled at the happy purple pony.

	Celestia's ears picked up the faint sound of plastic crinkling and pinpointed it's source. She looked at Twilight's dress covered flank and then at Twilight. "Taking home a little souvenir?" Her horn started to glow as she lifted up the hem of the dress slowly.

	Twilight blushed and lowered her head shyly. She stepped away from the two and shooed away the magical aura that was pulling at her dress. She managed to stop it just in time for the thick diaper to show through for a second. "C-Cadence said I can't waste it and not take it off until it's full."

	"Maybe you can get your loyal assistant, Spike to change it," Celestia teased quietly.

	Twilight recomposed herself, straightening up in a typical princess manner. "Yes well. Until next time, Princess Celestia. Princess Luna. Princess Cadence."

	"Fair thee well, Princess Twilight." Celestia returned the level of prim and properness, bowing her head regally. "Until next time!"

	"Remember, don't waste the diaper!" Cadence reminded her as she walked towards the door.

	Twilight bashfully looked at the other ponies as the door opened, "I-I'll have it leaking. Promise!" The other ponies seemed to like that, allowing her to walk out.

	The same carriage as yesterday returned to pick up Twilight. The guard ponies bowed from their harnesses in the front.

	Twilight carefully climbed into the carriage, trying her hardest not to let any of her diaper peek out. When she finally got into it and was able to sit down without risk of her diaper being exposed, the purple princess pony was able to relax.

	The carriage pulled away from the castle, heading down the main road back down towards Ponyville. Twilight just about forgot about her diaper save for the occasional brush up against it and the cool spot where her orgasmic juices had been soaked up.

	Twilight was much looser than when she arrived. She was noticeably much more relaxed and carefree. The new princess was now completely stress free...For now.
