The Beginning

The wide open expanse. The risky thrill of getting caught. These were the details that made the Canterlot Castle throne room so tantalizing for Princess Celestia. Just the thought of somepony seeing her...like this made her legs quiver as fantasy dominated actual reality. She had waited for this moment for weeks and every second that ticked away tasted all the sweeter as the anticipation was devilishly stimulating. She was finally here!

She knew there was a very small chance of getting caught, especially during this time of day. The late afternoon was never a time of high activity around the castle as most ponies grew lazy right after lunchtime. Very few ponies even ever visited the castle at this time of year anyway, too busy enjoying the last few weeks of summer while they could. The perfect time, as Celestia planned, to indulge in her secret desires. She had chosen this time perfectly.

A diaper crinkled around her waist, something that was usually quiet had its sounds amplified tenfold by the tall walls of the room. She could hear every rustle of the garment echo off the walls and columns as if reminding her of her naughty deed. It was as if the very walls knew that the Princess of the Sun shouldn’t be in a diaper. She was being very naughty wearing such a thing. Each step made the fresh diaper brush against her inner thighs oh so softly, sending tiny bolts of lightning through her body. Exposed and public. She was actually doing it!

She now stood in the middle of the throne room, dead center of the royal red carpet that stretched far into the distance. Behind her stood a raised platform and some steps leading up to a pair of golden thrones where she and her sister would sit on any given day. To her left and right stood thick, marble pillars that shot high up to the ceiling far above the alicorn. Beyond those columns of pillars were stained glass windows and tall, peaked windows cleaned to a crystal clear finish.

Through the windows she could see a cloudy sky outside. Looked like rain, but what COULD have been there is what really fueled the princess’s active imagination more than what was actually there. There could have been pegasus guards flying by, adventurous ponies spying on the princess during her private time, a zeppelin filled to the brim with tourists peering into the castle. Perhaps even sneaky paparazzi ponies with cameras ready to take a revealing photo of the diapered alicorn. The thought of it all made her breathing quiver. What a rush!

Her thick, white and gold diaper bulged out between her legs, emphasizing her curves with its thick padding. Her legs bowed out broadly as she made no attempts at walking normal with such padding. It’s bulky padding made her waddle, so she allowed them to make her waddle. The plastic diaper crinkled with each step she made. No matter how much she tried to be graceful or normal, her diaper would always crinkle to remind her of her embarrassing state. She was in a diaper and it would be difficult to forget that. Not that she wanted to. She was diapered and out in the open and she couldn’t have been happier!

She took one last glance down the length of the throne room as her back legs stepped wider apart. Not a soul in sight, but there was so much open space. So many places for ponies to hide and spy on the diapered princess. So many nooks for hidden cameras to conceal themselves. In reality, she wouldn’t have to worry about any of these things actually happening, but fantasy made the very idea of them existing enticing for the diapered princess. A reality she'd dread, but a fantasy she lusted over!

A pressure grew in her gut as a smile grew on Celestia’s face. It was time. All that cider and cake she filled up on not hours ago as a second lunch were finally reaching their end. She slammed her eyes shut, shamelessly thrusting her rump into the air. She pushed with all her might, bearing down on her full bowels and bladder. Years of potty training tried to interfere, but she pushed right past those initial instincts. She wanted this. She wanted this exposure!

Her bladder was the first thing to go. After some careful shifting and relaxation of her muscles, Celestia was soon rewarded with a loud hissing that gurgled and sprayed into her diaper. The thirsty padding swelled between her legs, quickly warming up with a yellow spot that quickly appeared and spread far across her absorbent diaper. The white face of the padded garment quickly darkened and yellowed, advertising to the invisible crowds she performed for that the Princess of the Sun, had in fact, wet herself. How very naughty and unprincess like of her!

Her bowels followed shortly after. Once her bladder had opened the doors to her public diaper fill up, Celestia found it much easier to mess herself. Perhaps it was tapping into some long forgotten instinct that she had overlooked when she was no longer a foal. Perhaps its was just her body’s way of figuring if she already wet her diaper, there was no reason to stop her from going all the way. Whatever the reason, her bowels were finally obeying her command, and Celestia soon felt the pleasurable release of publicly pooping herself.

The mess started small and slow, pushing out the back padding of her diaper before the load plopped into the midsection where the diaper hung so grossly behind her. A satisfied moan slithered out of her mouth as she continued to push, filling the diaper with a hefty load that she had been saving up specifically for this occasion. The firm but squishy load filled out any wrinkles in the diaper that her urine failed to even out as she continued to publicly soil herself.

Her eyelids flickered as she took in a shaky breath. Her wings vibrated with a pleasurable buzz. What a rush! She had actually soiled herself in public! There she stood in the middle of the throne room, wide open space in all direction, and she was in a diaper, a wet and messy diaper.

Without turning her head, Celestia hooked a hoof around to press into the lumpy back of her diaper. She could feel the squishy material ooze about as her hoof pressed it into her rump. The touch felt electric as she gave the new mess a series of testing squishes. The feeling tingled as she squeezed her thighs together. That was one wet and stinky diaper.

Celestia giggled, wiggling from hoof to hoof like a happy toddler. She actually did it! What a rush! She felt like she could have danced and giggled all over the throne room like this. And nothing would get in her way!

Suddenly she heard a deep voice clearing his throat, causing her blood to instantly run cold. Her neck snapped back behind her to see a golden armor clad unicorn guard staring back at her. The color drained from her face as her eyes widened. She stared back at the guard completely paralyzed with fear. Her mouth hung open, petrified, as words failed to form.

The guard didn’t break his straight expression, despite seeing the proud Princess of the Sun standing before him in a messy and wet diaper. His intense military training made sure his ramrod poise was unwavering. “Princess Celestia, you have a...visitor.”

The cyan maned unicorn stepped aside as he motioned towards the pony behind him. Twilight Sparkle, Princess Celestia’s most esteemed pupil stood there slack jawed and wide eyed. The purple unicorn stared at Celestia with equal amounts of surprise and fear as they could only blink at each other.

Celestia’s cheeks now flared up a bright red, redder than she ever thought possible. She fantasized about being exposed and caught, but only in the realm of conjured fantasy. Now that she was finally experiencing it for real, she could only feel cold terror and intense humiliation. This wasn’t what she wanted!

“Twilight!” the stammering princess exclaimed, “please don’t look!” In a fit of panic, all she could think to do was cover her blush covered face with a white wing and cover her diaper as best as she could with her tail. To no avail, the diaper still bulged out predominantly behind her.

Twilight only blinked, hardly able to comprehend the sight. “Princess?” the dazed purple unicorn simply replied, barely able to react.

“Please...don’t look!” Celestia repeated with a squeaky voice, “leave at once!” She forced every ounce of authority in her command, but only ended up with what sounded like a weak, pleaful whine.

The guard hardly hesitated, too disciplined to fully react at the strange sight. He quickly bowed his head and trotted down towards the throne room’s exit. There was no doubt that his loyalty and training as a guard would prevent him from blathering on about what he just saw. He wouldn’t tell a soul, there was no doubt about that.

Twilight on the other hand was a loose end. To the panicking Celestia, a loose end was just enough to expose herself to the entire world. Even a well learned pony like Twilight Sparkle whom knew the princess for years couldn’t be trusted with such a secret. She couldn’t let the unicorn simply leave knowing what she knew. This was something she couldn’t let happen.

The shocked unicorn took a moment or two to finally budge from her spot. She started by stammering a panicked apology as she struggled to fully digest what was going on here. She slowly turned around and made a frightful dash for the main doors, too embarrassed to even say goodbye to her mentor.

Out of nowhere Twilight suddenly felt her limbs freeze up like they were made of stone. She was stopped dead in her tracks with a forehoof raised off the ground in a half step. She strained against the mysterious force that suddenly overtook her body, unable to break free. She was stuck! Looking closer at her frozen hooves, she could spy a faint, golden aura glowing around them.

“I-I’m sorry, Twilight, I have to fix this,” Celestia stated. Her horn began to glow gold and then a bright white. Soon the light grew to such power that it blinded the two, engulfing the room in its bright radiance.

Author's Note

After a loooooooong hiatus, I return with a small story I've had on my writing desk for quite some time. This story is a bit on the experimental side of things in that it contains multiple endings. While brainstorming for this story I couldn't settle on just one ending, so I decided to experiment with multiple options. Technically the "official" ending is the last chapter marked "The End", but the chapters in between experiment with other themes I felt like exploring.

Outcome B - Birds of a Feather

Twilight’s vision slowly came back to her as the black, foggy haze over her eyes seemed to dissipate. Right away she had to squint, as the warm afternoon sun shined brightly into her face. She tried to raise a hoof to shield her eyes from the hot sunlight, but found them resisting her commands somehow.

Her eyes began to open wider as more of the world around her took shape. Blurry images slowly focused themselves into city buildings and shops and pedestrians. She found herself now at a busy intersection of Canterlot, bustling with activity during the busy afternoon. Dozens of ponies trotted by as she could hear voices and noises all around her. Slowly everything began surging back to her senses.

Her mind was groggy and slow to start as confusion and disorientation fogged it up. She could faintly recall going to the castle to meet Celestia in the throne room. She had planned to catch up with her long time mentor, but she wondered why she was out here in the middle of the street. Everything between then and now was all a blur.

As she scanned the area, some ponies began to slow down, staring back at her. Their walking grinded to a halt as they looked at Twilight with expressions ranging from shocked to puzzled. At first a group of two or three stopped to look at the purple unicorn, but than more began to take notice, amassing into a growing crowd.

Twilight could only stare back, equally as puzzled as some of them appeared to be. Just what were they staring at?

It was only now that she took notice of a certain bulkiness between her legs. Like a fluffy pillow was preventing her thighs from touching. She gasped when she noticed a thick diaper taped around her waist, causing her back legs to wobble a bit in shock. The bulbous, white and lavender padding stood out like a sore thumb against her purple coat, which only seemed to emphasize the yellow hue around its midsection even more.

She squirmed in place, desperately trying to cover up the large diaper that a dozen eyes around her stared at. She was panicking, too fearful of the public eye to fully process it all. No matter how much she tried she could only fidget a bit, even when she wanted to run away. Every angle she turned, there'd be five sets of eyes staring back at her and her humiliating situation.

Most of the ponies around the embarrassed unicorn just stared in disbelief or disgust. Some even snickered or flat out laughed at the hilarious sight. Regardless of their reaction, the spectacle garnered quite the crowd. As Twilight fidgeted and became increasingly aware of her soggy diaper that grew warmer by the second, there were at least fifty ponies surrounding her.

Twilight was forced to endure the passing comments and the stares of the ponies around her. Her diaper crinkled and squished loudly with every move she made. She now could move her legs up and down, and even spin around in place, but somehow was still unable to move from her spot. Something unseen compelled her not to do so. She raised a hoof to cover her face in shame. It was the only thing she could really do at this point.

Suddenly her stomach began to gurgled, causing the color from her face to drain. She felt the overwhelming urge to turn around so that her thickly diapered rump was facing the audience to which she followed without a second thought. Her stomach churned and ached as she crouched where she stood, sticking her diapered butt up into the air.

Loud grunts could be heard from Twilight as her bowels automatically began to empty themselves. Tiny spurts of gas could be heard as visible lumps bulged out the back of the diaper. Her soft mess tinted the back of the diaper with a slight brown coloration as she filled the diaper up for all to see.

When she was finished, Twilight regained control over her body, but she didn’t want to look up. She didn't want to face the countless crowd of staring ponies that watched her publicly soil herself. She knew that the longer she stood like this, the more ponies could see her heavily used diaper, but she was too petrified with fear and shame.

Gasps and whispers could be heard from the crowd as more and more ponies gathered around the thickly diapered unicorn. Passing comments and quiet laughs were made as everypony couldn’t help but stare in disbelief. Everypony wanted to get a good look at the disgusting sight of the purple unicorn who publicly soiled herself.

After a good ten minutes of having her butt raised high into the air, Twilight finally lowered it in shame. She suddenly felt her body being released from whatever invisible bindings that kept her there, allowing her her freedom.

Twilight took full advantage of this and quickly made a mad dash out of the area. Her legs bowed out wide as she hastily left the scene, desperate to escape the prying eyes of the fifty or so ponies who stared and laughed and whispered. Her tail could only partially cover the bulging diaper that sloshed and shook behind her.

A fair distance away from Twilight's pubic stage, Celestia watched this all unfold from a tower's balcony. “I’m sorry, Twilight,” Celestia mumbled to herself as she watched the embarrassed diapered unicorn waddle out of sight as quickly as possible. “I can not trust that you'll keep my secret unless you go through something worse. This is all necessary to keep the public eye off of me.”

When Twilight finally disappeared Celestia took in a deep breath. She panicked, but this was all necessary. To rationalize such a drastic decision she kept telling herself this. This was all necessary.

Outcome C - A Typical Playdate

She didn’t know when she closed her eyes, but suddenly Twilight found herself waking up from a foggy slumber. The gentle waft of baby powder and lavender tickled her nose as she opened her aching eyes.

She was still in the Canterlot Castle throne room like before, but something about it felt a little off. She now sat in the middle of the room, on top of a large pink playmat. Other than the smell of diapers and the large toy chest that sat on the edge of the playmat, the room seemed unchanged. Although, the more she thought about it, Twilight couldn’t quite recall what it looked like before than. She just felt like something felt off.

“Twilight?...Twilight? You alright?” Celestia’s voice slowly came into focus as it started muffled and grew clearer over time. Twilight turned her head to find Celestia sitting beside her on the mat. A thick, soggy diaper squished between the princess’s legs as she so peacefully sat beside Twilight. She looked to the unicorn with curious eyes, honestly invested in what Twilight had to say.

The purple unicorn blinked deeply, rubbing her eyes as a fog lifted from her mind. “What’s...What’s going on?” Twilight asked as she continued to rub her head.

“We're having a playdate, remember?” Celestia stated as her horn began to glow yellow. “You wanted to come over and diaper up with me.”

Twilight felt a minor pain in the front of her mind, causing her to flinch and rub the invisible pain. “You sure?...I don’t remember-”

Celestia’s horn suddenly began to glow again, taking on a bright light that caused Twilight to cringe a tiny bit more. “Of course. Just like a dozen times before. Remember?”

Twilight rubbed her temples, “really?” She flinched at another twinge of pain. “Yeah...I guess that makes sense...”

The glow on Celestia’s horn began to die down as she smiled. “You do look very cute in a diaper,” the alicorn chirped, "I never realized it before."

Only now did Twilight notice the large diaper taped around her waist. The diaper was white and lavender, styled to look like a real baby diaper with ample padding for larger ponies. Before she could fully examine the garment, an invading, white hoof stretched inwards and pressed into the diaper’s front.

“Soaked too,” Celestia stated as her hoof pressed into Twilight’s swollen diaper, feeling the warmth of a freshly soaked diaper. Once again, Twilight struggled to remember a time when the diaper wasn’t wet. “Don’t worry. The babysitter will change you.”

“Babysitter?” Twilight replied puzzled before raising her head.

Out from her peripheral came in the same unicorn guard from earlier. He wore the same armor as before, but again, Twilight couldn’t quite remember whether or not that before actually happened.

“Yes, your highness?” the unicorn stood there at attention with his head held high.

“My faithful student, Twilight requires a diaper change,” Celestia plainly stated before her horn glowed a bit. “would you please change her?”

The unicorn flinched for a second or two. An off putting twinge in his head caused him to break his usual disciplined pose just for a moment. He squinted, rubbing his temple for a moment or two. “O-of course, your highness.”

Twilight still struggled to digest what was happening around her. She couldn’t quite remember ever doing this sort of thing before, let alone with Princess Celestia. She struggled to find a genuine memory where the two wore diapers together. Even as she dwelled on the thought, memories of the two wearing diapers together felt...off. They felt almost artificial. As she was gently laid down on the ground for her diaper change, the unicorn tried to sort through the mental debris.

The unicorn guard did seem familiar though. Perhaps she had been doing this thing before. And a vague image of Celestia standing with her legs bowed out and a well used diaper sagging between her legs further supported this suggestion. Perhaps Celestia was right. They always did this sort of thing...Right?

“Legs up please,” the unicorn guard said as he lifted Twilight’s legs high into the air with one hoof while sliding her old diaper out from under her.

“And then, when you’re done with her,” Celestia stated as she waddled up to the two, “you can help me with mine.”

The unicorn guard nodded passively as he pulled out a tub of wipes. “Yes your highness,” he plainly stated, pulling out wipe after wipe to clean Twilight up.

As Twilight was being cleaned, Celestia spun around so that her soggy diaper butt was close to the other two. An adrenaline rush tingled her spine as her legs bent out slightly. No more than a foot away from the unicorn guard's face, Celestia began to grunt and push.

It didn’t take long for a large lump to grow in the back of her diaper before the stinky load plopped into her already saggy diaper. The mess pushed out the padding only slightly before squishing against her butt and adding to the pile of stink that grew inside of the diaper.

Celestia felt invigorated from the experience. Here she was messing her diaper in the middle of the throne room like before, only this time it was done right in front of Twilight. And all it took was a simple series of memory alteration spells! She couldn't figure out why she hadn't done this sooner!

When she was finished with her dirty deed, Celestia pressed a hoof into the lumpy back of her diaper. “Feels like you got your work cut out for you,” she grinned naughtily as she leaned her stinky diaper butt towards the unicorn stallion.

The guard was visibly put off by the princess soiling her diaper so close to him. His face curled up a tiny bit in disgust. But when he thought to have a thought to decline, he felt his forehead burn and sting for a short second. “Y-yes your highness.”

Despite the gross spectacle of watching the princess soil herself in the middle of the throne room, the unicorn guard didn’t lose a beat in his diaper change. He expertly powdered Twilight’s crotch and began pulling the front of her new diaper up between her legs and taped it snuggly around her waist.

“I’m next!” Celestia exclaimed, plopping noisily on the floor right beside Twilight. The purple unicorn hardly had time to sit up before the messy diaper clad alicorn flopped beside her. The unicorn guard went right to work, hardly gagging at the smelly diaper was untaped. “And then when we’re done, we can start playing with our toys. Would you like that, Twilight?”

Twilight felt the familiar stinging sensation in the front of her mind, causing her to flinch before she answered, “yeah,” she replied, “yeah, that sounds like a lot of fun!"

Outcome E - Creative Processes

“Discord? Discord!” Fluttershy’s voice echoed off her cottage walls as she trotted through the rooms. Tiny animals scurried out from under her as she walked through the house, searching every nook and cranny. “Discord? Where are you?”

Suddenly in a white flash, the draconequus, Discord, appeared before the yellow pegasus. He was wearing a dark brown writer’s jacket with padded elbow pads. A smoking pipe floated beside his head as a writing desk floated next to him. On top of the desk rested a stack of loose papers and an inked quill.

“Yes, Fluttershy, what is it?” Discord asked before taking a few puffs of his pipe, producing bubbles from the pipe’s bowl.

“Oh, I’m sorry, I didn’t know I was disturbing you,” Fluttershy meekly backpedaled, “I was just wondering if you’d be joining us for lunch.”

“Afraid not,” Discord answered with a dramatic backwards whip of his neck. “I’m much too involved in my creative process to stop now.”

“Oh? I didn’t know you were an author,” Fluttershy commented, “What are you working on?”

“Oh it’s a bit of a romantic piece. A short story about a pony who’s caught indulging in one of her vices by one of her most trusted colleagues,” Discord described his newest work with a dramatic flare, making it sound like his greatest masterpiece. “Only I seem to have gotten stuck.”

“Writer’s block?”

“In a way,” Discord replied, leaning forward to look over the random sheets of paper that floated just above the writing desk. “I’m having trouble settling on an ending. I have so many ideas for possible endings, but I can’t just settle on one.”

“Maybe just keep it simple,” Fluttershy meekly suggested, “have the characters become friends and live happily ever after.”

“Hmm, I don’t know,” Discord answered, rubbing his chin, “that feels too...simple...”

“Simple might be what your audience wants,” Fluttershy answered, “sometimes a story is best left a bit open ended so the audience can draw their own conclusions.”

Discord rubbed his chin in thought, “well, I suppose I could have Twili-...the pony’s colleague flat out admit she likes the main character’s...vice and join in.”

“See? Simple,” Fluttershy smiled, “at least it’ll wrap up your story so you can move on to other projects.”

“Perhaps you’re right,” Discord answered, “my fans do need to be appeased. I cannot spend my whole life on just one project.”

“That’s the spirit!” Fluttershy exclaimed as best as her soft spoken demeanor would allow.

Outcome A - A Fresh Start

A unicorn couple crowded closely around a plain looking basket. Up from the basket, staring back at them, was a little pink foal. The filly looked at the two other ponies with the widest eyes, innocent and unfocused.

She had the prettiest lavender eyes and had her pink and lavender mane tied up in the frilliest of bows in a set of pigtails. Peeking out from the filly’s mane was a tiny, underdeveloped horn that still had a few more months left before it could possibly cast any magic. Her body was tiny, frail, and stubby, a typical thing to expect for a pony her age.

The two unicorns who looked down back at the small filly were a young couple who had yet to have children of their own. They were deeply in love with each other, but parenthood would have been a big step for the two. Both of them had their reservations with taking such a big step, however it was mostly nerves at this point.

“And you just found the poor dear out on the doorstep by her lonesome?” the mare unicorn looked down at the tiny filly who idly drooled on a suckling hoof.

“‘Fraid so!” the unicorn stallion replied, “little thing must be scared to death!”

The mare nodded, looking down at the foal with warm and understanding eyes. “You didn’t see anypony? Hear anything?”

The stallion just shook his head, “nu-uh, alls I could find was this note.” He held up a plain sheet of paper that was once folded and attached to the outside of the basket. On its face was a few lines of writing, written in elegant calligraphy.

“'This little filly is in dire need of a good home and good parents. I cannot provide these for her, but I just know in my heart that you two would be able to.'” the stallion paused to give his wife a passing and affectionate glance. They smiled at each other lovingly before he finished up the note. ”'She’s very young, but she cannot go back to her old life. Please take good care of little Dayglow.’”

“Dayglow,” the mare repeated to herself, “you really think we’re ready?”

The unicorn couple looked at the note, then at each other, and then at the foal. The pink foal just stared at them with wide, blank eyes, occasionally blinking with a puzzled tilt of her head.

“I think we can do it,” the stallion replied with a confident smile.

“Yeah, I think so too,” the mare answered with an equally confident smile. Her horn began to glow as she lifted the little, pink filly out of the basket and into her arms. “Welcome to the family, Dayglow.”

The little foal smiled and cuddled into the loving arms of her new parents. Years from now the young pony would have the faintest of memories cropping up in her head that she would know for sure didn't belong to her. Memories of a white pony who panicked and hastily used her magic to regress a purple pony to the age of a foal. This white pony would even go as far as to changing the purple pony's mane and eye color to further cover up her mistakes. Dayglow would never really make any connections to these rogue memories and pass them off as something she read in a book or dreamed about. She hardly needed to trouble herself with silly things that may or may not have happened.

Years from now she would even catch the interest of Princess Celestia as her skills with magic earns her the alicorn's mentorship. The Princess would show a deep devotion to her new student and likely commit even more time and energy into this one out of some unknown guilt for the young unicorn. Despite having a new pupil, Celestia would find it difficult to separate the present from that fateful night when a panicked regression spell lost her a star pupil.

As Dayglow grew older she would care less and less about the fragmented dreams and half remembered memories that floated in the dark recesses of her mind. None of that mattered anyway. What did matter was that she had parents who loved her and she had her whole life ahead of her.

Outcome D - Backfire

“Twilight?!” Luna exclaimed as she darted into the room, “I came as soon as I heard! What’s...”

Being called into the throne room with an urgent message from Twilight was certainly something that would put Luna in a bit of a panic, something that certainly merited a bunch of questions from the blue alicorn. However, when she arrived in the throne room and saw her sister crying on the floor with a heavily used diaper around her waist, a lot of Luna’s questions were answered. And of course, such a sight created a dozen more questions that needed answers.

Twilight stood near the door shaken up with worry when Luna arrived. The foul smell of burnt magic charged the air with an off putting scent as the unicorn was lost for words.

“Twilight...” Luna started again, much calmer this time around. “What exactly happened here?”

“Sh-she was charging at me,” Twilight answered with a rattled voice, “I-I panicked and i-it just sort of happened in defense! I didn’t mean to-”

Luna was quick to console the panicked unicorn. “It’s quite alright, young Twilight. It was an accident.”

“I-I was just scared, you know?” Twilight’s voice quivered, “I-I wasn’t trying to-”

“You’ve done nothing that cannot be undone, Twilight. Accidents happen,” Luna handled the problem calmly, occasionally glancing down at her regressed sister who was starting to stink up the place with her messy diaper. “I admit the result isn’t...typical, but a quick defensive spell is far from permanent.” She used her magic to levitate the crying white alicorn into the air and gently rocked her in place. That seemed to calm Celestia down quite a bit as her loud bawling slowly devolved into quiet sniffles. “My sister will be back to her old self in a few days.”

“A-and...until then?”

“Until then...well...” Luna paused, looking at her regressed sister who now occupied herself with chewing on her hoof, “how good are you at changing diapers?”

“Well...I guess I have some experience,” Twilight answered, wiping the tears out of her eyes.

“Oh good, because...” Luna’s words trailed off as she caught another whiff of Celestia’s diapers. She felt her face turn green as she plugged her nose with a hoof. “Because she could certainly use one...”

“I’m so sorry, Celestia,” Twilight apologized to the regressed pony, “I-I’ll make it up to you. I’ll keep an eye on you every day until all of this rights itself!”

Celestia giggled and kicked her hooves a little bit in the air. In a strange way, Twilight felt like she was accepting the apology. A few days of this. Then everything would be back to normal.

Outcome F - Happily Ever After

In the middle of the royal throne room, Celestia and Twilight stood across from each other. They remained locked in a staring contest of wits. Celestia wore a well used diaper, as wet as it was messy. Twilight wore a shocked expression, surprised and slack jawed.

"Oh Princess Celestia! Why didn't you tell me sooner!" Twilight exclaimed. "I LOVE diapers!"

"You do?" Celestia was genuinely shocked. Who knew her most esteemed student was into the same stuff as she was. "Gosh I always thought to tell you, but I was always scared you'd think I was weird."

"You're not weird for wearing diapers, Celestia!" Twilight assured her. “In fact,” she added, ripping off her soft blue robes that she had been wearing this whole time, revealing a thick pink diaper. “I’m wearing a diaper too!”

“Wow!” Celestia exclaimed, happier than she ever could be, ”I never knew!”

“Now we can wear diapers together!” Twilight added.

“I would be happy to! I’m so happy to have found a pony who shares in my vices!”

Outcome G - The End

“Right this way, Ms. Sparkle,” the cyan maned unicorn guard bowed his head as he motioned an armored hoof towards the large double doors beside him.

He pushed open the tall wooden doors as they effortlessly gilded apart with neither a squeak or creak. The doors opened up to an expansive throne room. A long red carpet led the way as the two ponies trotted down the room’s marble floored length.

On the other end, standing so elegantly before her golden throne was the Sister of the Sun herself, Princess Celestia.

The white alicorn smiled down at the purple unicorn as she so gracefully bowed her head. “Ah young Twilight, what a pleasant surprise!”

“It’s nice to see you, princess” Twilight said as she bowed her head deeply, “sorry for the surprise visit, but I realized how long it’s been since we last talked.”

“I must admit, I was not expecting you to show up so suddenly,” Celestia answered, “but no matter. I was not in the middle of anything...embarrassing...” She paused, staring off to the side for a second or two before looking up at Twilight. “It would be nice to catch up over some tea,” She smiled as she trotted towards the left of the throne room where a hallway leading to the royal gardens could be found.

She looked behind her to find the purple unicorn stopped in her tracks. A quizitive expression hung on Twilight’s face as she appeared deep in thought.

“Is...something wrong, Twilight?” Celestia asked.

“Uhm...no...No, Princess, everything’s fine,” Twilight shook her head, “just...feeling a bit of deja vu.”

“Deja vu? How odd,” Celestia commented.

“Yeah...almost like...I’ve done this exact same thing a couple times before,” Twilight thought out loud as she followed Celestia out of the room, “only a little different, you know?”

Celestia paused, “I’m...afraid I don’t know, sorry. But you can tell me all about it over some tea. That should soothe the nerves.”

“Yeah,” Twilight said as she rubbed the front of her head for a moment, “tea would help settle this headache.”
