Twilight dabbed one of the twenty or so quills in her magical grasp into their shared inkwell, eeking out the last few drops from it she could. She snapped it back over to one of the many waiting papers, scribbling her name at the bottom. The other quills duplicated the action with their own documents, creating a scratchy chorus to fill the throne room.

She bit her tongue in concentration, eyes narrowing at her pile of royal paperwork still waiting. Even as she whipped through nearly two dozen pages at once, it felt like she was barely making a dent in the scores of documents that covered the Cutie Map. Not exactly a comforting thought, given that her weary eyes fluttered closed every so often. The tantalizing prospect of taking a rest seemed more and more like an impossibility.

It didn’t even seem to matter than she had been tearing through work for the past three hours this way; the mountain of paperwork before her was far from the molehill she wished it was.

“Sweet Celestia,” she muttered under her breath. Heavy eyelids threatened to slam away the sight before her.

Her signatures soon became scribbles, and the scribbles became blobs of ink. A yawn overtook her, dropping half her quills before she was able to shut her mouth. How late was it again? How long had she been up again?

With no windows in her throne room these questions went unanswered. But Twilight hypothesized Celestia had long since lowered the sun. Her brain had started winding down already, and she could feel her body catching up. She didn’t feel all that sleepy even, but worn out for sure.

Another yawn and the rest of her quills gave up. They clattered to the ground and Twilight wished very much to follow their example.

But instead, she stood up from her throne and stretched all six of her limbs. Her muscles ached from lack of activity, making her wonder again just how long she’d spent working.

Looking back, just behind her throne, she could see the stacks of paper in her ‘done’ pile. Her head whipped around to the Cutie Map again as she compared it to her remaining work load.

Must’ve been eight hours. Twilight judged. Come to think of it, did I skip dinner?

Her stomach rumbled, momentarily tricking her into expecting a thunder storm.

And lunch? she added.

In fact, had she even stopped for a bathroom break?

Twilight shook her head, not wanting to think about the pressure in her lower hip she just now noticed. However long she’d spent working, it was clear that it had been too long. Right now, she needed food, a trip to the restroom and a nap.

“Errgh.” Twilight doubted she had the energy to get through one of those things right now, let alone all three.

But there is a way… A smile sprouted on her lips. It blossomed into a full on grin once she realized she had the answer to all her problems and more.

Spurred back from the near-dead, Twilight actually trotted out of her throne room, leaving hundreds, if not thousands, of scrolls to fend for themselves. Come tomorrow morning—or, maybe tomorrow afternoon—she’d be back to finish them all, but for now she was going to de-stress.

She flapped her wings a little, but didn’t have it in her to fly right now. Sticking to her hooves, she made her way through the halls of her castle. Moonlight leaked in through tall windows; Luna’s night had long since fallen.

That meant Starlight and Spike were probably already asleep. Good. She couldn’t let anypony know what she was about to do. If anypony ever found out about her… Twilight shook her head. She wouldn’t think about such unpleasant things.

Her stomach growled again. A pack of starving wolves were tearing each other apart inside her, it seemed. Her pace picked up even as her exhaustion multiplied. She was so close now.

Throwing open the doors to her personal library, Twilight was greeted by shelf-lined walls and book-lined shelves. Her vast collection towered over her as she entered, but it was not the reason for her visit tonight.

Scampering over to the left-most shelf, Twilight looked up to the third row and brushed a hoof-full of books to the side. They revealed a small switch, one that almost blended into the wall of the shelf. That was by design, as it would be so easy to glance over unless you knew exactly what you were looking for.

Twilight pressed the switch, the book shelf clicked and whirred lowly. Setting the books back in their place, Twilight stepped back as the heavy shelf swung open.

Her grin could only widen as her secret doorway revealed a spiral staircase, descending into the depths of her castle. Twilight trotted in place, holding back a delighted squee.

One step onto the staircase was met with a drastic temperature change. Twilight shivered against the frigid air, always forgetting how cold it got down here. She wrapped her wings around her body, rubbing her feathers against her coat in a bid to warm up. As she descended, bracing for more chills, it didn’t even occur to her to shut the bookshelf-door behind her.

The stairs spiraled downward, looping around twice before they finally reached the bottom; her castle’s basement.

Of course, Friendship Castle technically didn’t have a basement. This had taken Twilight a lot of time, a lot of magic, and a lot out of her personal piggybank to make a reality. But it was so, so worth it in the end.

The stairs reached their end at a heavy steel door. One small window near the top provided the only light source in the stairwell. The light was always on; Twilight had affixed a permanent power source to the rooms beyond this door so they’d always be ready for her. And out of paranoia, she’d added two back-up generators as well.

With heavy eyes, but a fluttering heart, she turned the doorknob and pushed it open.

The light that had been trickling through the window now flooded the stairwell. Twilight blinked and narrowed her eyes, familiar with the routine by now. When her pupils adjusted, everything became much more clear.

She smiled as she took in her favorite room in the castle: the nursery.

Snow white carpet met her eyes first, still a little hard to look at as her eyes grew used to the light. It covered the floor of the room, stopping only to make way for padded walls made of pale purple felt. Little white stars and red hearts dotted them in simple, repeating patterns, only stopped by the presence of two doors on the opposite side of the room.

The carpet was littered with foalish amenities. A tall crib and matching mobile stood in the right corner, just big enough for Twilight with a little wiggle room left over. Right next to it was a changing table and a dresser stocked exclusively with thick adult diapers. There was a pail for the used ones close by, too. A playpen dominated the corner across from there, swallowing up a generous amount of space to hold all the baby toys contained within it.

The center of the room was filled with all the toys too big for the playpen such as a walker, along with a baby bouncer just above that. Beside them sat a plastic easel and paints, left in a decidedly messy state. A training potty was close by, practically at her hooves. Meanwhile, near the wall and in between the two doors was a folded up baby carriage and stroller. Just before them was a cutesy plastic table and matching chairs all filled with stuffed plushies save one, with a tea set all set up.

To the left sat decidedly less foalish things. While the high chair certainly kept the spirit of the room thriving in that territory, the wardrobe, heart-shaped vanity, fridge, and small wooden stool were of a more neutral nature. But Twilight had at least managed to liven them up with liberal application of a pinkening spell.

Scattered about the room, from the floor to the ceiling to all four walls, were individual little holes, all closed up by metal doors. They were connected to the last detail of the room, this one right next to the doorway where Twilight stood: a small monitor.

This was her “true” kingdom. Twilight had been an adult foal for as long as she could remember. What had caused? Any number of possibilities, really. Her mom’s consistent coddling, needing diapers for bedwetting well into her teens (and a foalsitter, for that matter), Princess Celestia as a personal secondary mother figure… It didn’t really matter which one had done her in, because here she was now.

A nursery like this, it had been a part of her wildest dreams for a long time, but only after becoming a Princess could she make it a reality. The only trouble was finding the free time to use it. Though, she found herself making time for it more often than not.

Twilight took a deep breath, absorbing the scents of foal powder, cheap plastic toys, and freshly cleaned linens. It triggered hundreds of memories, but more importantly the desire to create more.

“Twily’s home,” she whispered to the empty room, eyelids drooping with exhaustion. No more work had to be done today; she could finally relax.

Stepping inside and shutting the door, Twilight turned to the monitor and gave it a little tap. The screen flashed blue as the magical computer awoke. Eventually a smiley face and the phrase “Welcome back” appeared on the screen. It quickly gave way to a list of pre-programmed activities Twilight had done previously. She scrolled past all of them, however, selecting the “Free Play” tab.

The screen changed again, now displaying three sliding tabs, each numbered from one to ten.

The first tab was labeled “Mothering Level”. Twilight wasted no time in dragging the slider all the way up to ten. She didn’t want to have to do anything tonight. It would be better to let the machine dictate everything for her, even if that meant coddling.

For the second tab, labeled “Discipline Level”, Twilight paused. Normally, she’d keep it at around a five or six. Generally speaking she wouldn’t disobey the program, but those levels gave her enough room to be naughty while still letting her indulge in a few punishments should she choose to push it that far. But tonight she felt differently. She couldn’t afford for the program to let her goof off, as she was inclined to do whenever diapered. The slider found itself nudged all the way up to the nine setting. Not quite zero tolerance, but it would keep her on track without a doubt.

Lastly, “Adapting A.I.”. Her program recognized speech, but didn’t register vocal commands. It was up to the machine to intuit what she needed, based on all sorts of stimulus. Already, the program had learned enough about her these past few months to make this part a little unnecessary now. Still, Twilight only nudged it down to a four. It was best not to hamper the AI’s capacity to learn too much, after all.

With her sliding finished, a new pop-up appeared asking for confirmation. Too tired for second thoughts, Twilight tapped yes.

The screen went black. Above it, a section of the wall slid open and pushed two buttons toward her, one green and one red. Green was the obvious “Go” command and Twilight pressed it without hesitation, already breathing a sigh of relief.

There was a gentle hum behind the walls as her commands were inputted and the system booted up for real. Twilight’s heart pounded with excitement. It felt like it had been so long.

“Hello, little one,” Her AI spoke. It’s voice made her ears flick. Compiled from a sampling of her own mother’s voice, along with Celestia’s and Cadence’s thrown in for good measure, it made for the most affectionate sound Twilight had ever heard. “I’m delighted you’re backI”

“Me too,” Twilight said. She plopped down on her flanks, running a hoof through the shaggy carpet as she waited.

“Oh poo. Sweetheart, you’re not wearing your didees, are you?”

“I guess not,” Twilight giggled, hoof to her mouth. “Will you change me?”

“Of course, honey.”

There was a whirring noise, and two holes on the ceiling popped open. From them, gloved hands emerged, with flexible tube arms guiding them down to Twilight.

Beaming, she lifted her hooves up, letting the hands grab her under the shoulders and lift her into the air. She was whisked over to the changing table, her back meeting it’s cold surface with a shiver.

“There there,” Her mechanical nanny cooed. One hand reached below the changing table while another went for the top drawer of the dresser.

As tired, hungry, and in need of a restroom she was, Twilight couldn’t help but smile in anticipation. The dresser hand was ready first, pulling out a big, fluffy diaper.

A third hand came out of the wall to help it, unfolding the garment to reveal the sun design that would soon occupy her butt. Twilight giggled, knowing the sight of Celestia’s Cutie Mark anywhere. This particular brand, Sunnies, were notorious for the design. Their foal line of diapers were often a filly or colt’s first introduction to the monarch’s Mark. But for Twilight, it was more of a comforting sight than anything else.

The other hand returned from down below, cradling bottles of rash cream and foal powder in between its fingers. It tossed one down, just in time for an arriving fourth hand to catch.

The hands with the diapers approached her plot. “Upsie daisy,” called out the AI.

Twilight obliged, lifting her hind legs up in time for the diaper to land. One hand grabbed her tail and tucked it through the hole in the back of the diaper while another pushed the fluffy plastic under her butt.

Eager, Twilight brought down her legs before she even needed to be asked.

“Ah ah ah,” her Mommy’s voice tutted. A hand gently nudged her legs back up, denying her plot a chance to crinkle the diaper. “Not yet, sweetheart.”

Rash cream made it’s way to her under carriage, chilling to the touch. It actually got an “Ooh,” of surprise out of her.

Next came the foal powder, applied liberally to her bottom. The hand holding her back relented now, and Twilight spread her legs as she lowered them.

Her butt made poofy contact in milliseconds. Twilight’s sigh overpowered the crinkles she caused, and her fore hooves kicked with glee. More foal powder met her nethers, coating her with a protective layer. Now it was time for the main event.

The free hands grabbed the diaper and brought it up, wrapping Twilight’s waist in a perpetual hug of floof. She felt her marehood twitch with delight as the fluffy texture of her diaper made contact. Twilight cheeks blushed a light pink and for a moment, her eyes darted over to one of the two other doors in the room.

No, Twilight decided, immediately but regretfully. I’m too tired for that tonight.

Pushing off naughtier thoughts for another time, Twilight’s eyes returned to her diapering, just as the tapes were being smoothed down for her.

“There we go, little one,” Mommy said. “A nice, clean diapee, just for you!”

An ache in her bowels told her it wouldn’t be clean for long. “Tank woo,” Twilight playfully lisped. Though she needed to go, she wouldn’t force her Mommy to change her so soon.

Besides, her growling stomach all but demanded priority.

“Teehee, sounds like somefilly is hungry. Is that you?”

Twilight nodded, throwing her hooves to the air as she begged for upsies. “It’s me!”

Two hands took her again, lifting her up. The spares jumped back into their holes, their job done for now.

“Let’s fix that, shall we?”

Twilight was carried to the other side of the room. She could see hands already active over there, prepping the high chair and digging around in the fridge.

While she dangled in the air, Twilight looked down and grinned at her diaper. For the fun of it, she tried pushing her legs together. The predictable result had her hind hooves barely touching, while a swath of padding found itself pushed against her marehood.

“Mmmph.” Twilight bit her lip, longing springing to her loins.

She pushed down the feeling as her diapered plot met the seat of her high chair. There was a hiss as air escaped the diaper; it crinkled under her weight, but only compressed slightly.

Twlight kept her hooves up as the table of the high chair closed. Having her hooves free was a nice little bonus during meal times.

Two arms descended on either side of her, sporting a baby blue bib with white frills. Twilight didn’t complain as it was tied around her neck. Now everything was set.

A jar of foal food appeared on the table, a hand already unscrewing it while another hovered nearby with a spoon. When Twilight saw its label, she gagged a little.

“Broccoli?” She asked in dismay.

“Aww, but you need your veggies to grow into a big, strong mare one day.”

Twilight rolled her eyes, hooves slamming against the table. “But I don’t like broccoli!”

“Hush, little one.” The voice tone grew more stern, and cold. “Mother knows best.”

Twilight settled down, but her brow furrowed. She wasn’t just playing, broccoli flavored foal food was her least favorite. The only reason any was left in the fridge was because she was so stubborn about not eating anymore.

A hand came over and pinched her cheek, wiggling her face. “Oh, there there. Mommy will get you a new flavor after you finish this one, okay?”

Her stomach rumbled again, not as much of a picky eater as she was. “…Okay…” Twilight groaned. If it was just one jar, she’d live.

“Splendid!” The spoon dipped into the jar, withdrawing a large chunk of brown-green mush.

Twilight winced at the sight, mouth automatically scrunching as it neared. The spoon was undeterred, and nudged at her lips, trying to coax her to eat.

“It’s num-num time, sweetie! Open up your mouth for the choo-choo train.”

She groaned. “Fi—Mmmf!”

The spoon leapt into her mouth, taking a broccoli flavored dump on her tongue before popping out on the other side of her lips.

“Mmrr!” Twilight slammed her hoof into the tray table a few times. She was reluctant to swallow, but with each passing second the foul taste permeated her mouth more and more. She had to tighten her lips to fight the instinct to spit it out.

Eventually, she had to admit swallowing would be better than letting the taste accumulate anymore. Resisting her gag reflex, Twilight let the foal food slither down her throat. It landed to applause in her stomach, even as her taste buds booed.

Bits still lingered on her tongue and teeth, not letting her forget the nasty taste. But even if that weren’t an issue, the next trainful was already staring her down from the spoon.

“Choo-choo!” cheered her Mommy, the spoon going for her waiting mouth.

“Eergh!” Twilight groaned as the mush invaded her mouth once again. She was much faster to swallow this time, even as her hooves curled in disgust.

To her disappointment, she wasn’t out of the broccoli woods yet. Even with seemingly larger and larger spoonfuls each time, the jars themselves were fairly sizeable. It didn’t help that her Mommy insisted on scraping as much from the sides as possible, too.

But eventually, mercifully, the last spoonful of broccoli was defeated. She may have won every fight, but the mush certainly won the war. Everywhere from the roof of her mouth to her cheeks to between her teeth had a thin coat of broccoli flavored foal food now. The cost of victory, as it were.

Twilight squirmed as she flicked her tongue around her mouth, trying to clean up whatever she could to remove the flavor ghost from her mouth. Her dissatisfaction only lasted so long, though, as she soon saw her Mommy make good on her promise.

“Such a good eater. I think my wittle Twi-Twi has earned a reward.” Her Mommy set a jar of peaches down next to the empty foal food.

“Hmm!” It snapped her back to a good mood faster than she expected. “Yes please!”

“Hehe. Now I know fillies your age shouldn’t be taking solid food yet, but I trust my little girl is smart enough to chew.”

“Uh-huh!” Twilight nodded, her tail swishing in anticipation. Anything was better than broccoli at this point, but actual fruit? That was perfection.

“Okay then, sweetie. Open wide.”

Twilight was happy to oblige this time. Compared to the foal food, actual fruit was candy.

She ate like a starving pony, snout leaping for the spoon before the arms had a chance to offer it to her. The peaches washed away the lingering foal food. Twilight only picked up her pace. Normally she wasn’t such a messy eater, but right now she was hungry.

In her haste, she didn’t even notice the sticky peach juices dribbling down her chin, or the trace amounts that splashed onto her bib to join bits of broccoli mush.

She still didn’t notice them until her meal was finally done and a hand brought a napkin down to wipe off her face.

“Silly filly,” the nursery teased as it opened the high chair table. “You’re not supposed to wear your food.”

Twilight giggled. “Sorry.”

“Now then.” The napkin flew away from her face. “Who wants her baba?”

Twilight threw both of her hooves into the air, wings spreading in excitement. “Me!”

Two arms lifted her up again, while another four moved towards the center of the room. They linked up, forming a hammock with their arms. The hands all sat near the head to act as a makeshift pillow.

She was laid down, body sinking into the arms. Twilight flapped her wings as she nestled her head against the hands. Now that she was cradled, the nursery lowered a large foal bottle towards her.

The soft, amber nipple drew Twilight’s attention and the sloshing formula made her lick her lips. She reached up and grabbed the bottle with her hooves. Bringing the nipple to her lips, Twilight was suckling instantly.

It took a few seconds, but she earned her reward. Warm milk flowed into her mouth, filling her cheeks. She swallowed and suckled in rhythm, nestling against her makeshift hammock.

Curled up like that, she just about fell asleep. She was already dog-tired and now it seemed like the soothing act of suckling her bottle was going to put her out for the night. Her eyelids fluttered, hardly putting up a fight as they closed.

Twilight relaxed. No thinking, no moving, just suckling on her bottle. The milk drained swiftly, each cheekful eliciting a happy moan from her.

Once more, she felt her bowels push in anguish. Brow creasing, Twilight actually held them back at first. Then, realizing she was safe, stopped. And started pushing with them instead.

With nothing holding them back now, her desperate bowels gave way and Princess Twilight Sparkle finally pooped herself.

Her diaper bulged as the mess hit, crinkling as it made room. She had to grunt and push to force her first messy log out, chomping down on the amber nipple in her mouth as she did.

Once that one cleared, the rest came out almost readily. A hot, steaming mudslide hit the walls of her diaper, filling even more than the first round could have hoped. She moaned as her ache eased itself into relief, and returned to her suckling while she kept pooping.

The diaper was forced to expand even more now, and Twilight’s mess shuffled from her plot to her inner thighs as it looked for new places to go. Before long, her pristine padding was stained a rich shade of brown from its seat all the way to the crotch.

By now, the stink had wafted high enough to slap her nose into a wrinkle. Twilight actually stopped suckling now just to breathe through her mouth; the stench of her mess was too powerful for her to take.

Finally, she reached the end of her little bathroom break. Her soiled diaper had weathered quite a blow, but had kept everything contained as it continued its (now messy) hug around her plot.

Twilight grinned as her lips returned to the bottle. Bringing her legs together as best she could, she caused the warm and slimy mush to shuffle about. Her whole body shivered at the sensation, but most prominently was her marehood, which quivered longer than the rest of her.

As she tried to settle down, Twilight glanced back. Her gazed lingered at one of the doors. For a moment she really considered going back there. But then her exhaustion kicked in. Not tonight, Twilight decided, yawning. I need to go to sleep.

A new hand descended from the ceiling. “Uh oh,” the nursery gasped. “Did somefilly have to go poopie?”

Twilight smiled. She knew where this was going. The new hand snuck down to her diaper, hovering over it for just a second. Then it’s fingers touched down, invading the brown stain.

“Unnf~” Twilight bit her bottle’s nipple as sensations flooded her. The fingers dug into her diaper, exploring her crotch for just a moment before it drifted to the lumpy seat of her padding.

The palm joined in for this one as it groped Twilight’s mess. Her dirty diaper jostled at the touch. She gasped with delight. Diaper checks were always the best.

“Seems you did, Mush Tush,” the nursery teased with a giggle. The hand retracted all to soon. Twilight whimpered as it left, leaving her more pent up than before.

Once again thoughts drifted to the door across the room. She chased them off with a yawn.

“Aww, are you a sleepy filly, Twi-Twi?” The nursery asked her.

“I am.” She yawned again. Her mess’s warmth cradled her backside, lulling her closer to sleep. She dropped her bottle from her mouth and raised her hooves. “Can I go to bed now?”

Mechanical arms uncoild from the hammock below her. Hands grabbed her once again and she was in the air.

“Let’s get you changed first.” A finger booped her nose. “And perhaps a bath is in order, Stinky Pants.”

Twilight groaned. Really? She was tired. And she even wanted to go to bed messy.

“I said I’m tired.” Swinging her legs toward the crib, Twilight tried to make it obvious to the AI what she wanted. She regretted the lack of vocal commands now. They’d be pretty useful in situations like this.

“In a minute, sweetie.” The nursery carried her over to the changing table with casual ignorance.

Twilight grunted, crossing her hind legs. The mess in her diaper was still warm and squishy; she wanted to fall asleep like this if possible. Why was her nursery ignoring her?

Maybe I set the mothering algorithm too high, she mused as she squirmed about. Or maybe the adapting one is too low.

Regardless, she struggled out of the hands’ grasp. Dropping to the floor was awkward with her spread gait, but she managed to stay on her hooves despite some squishy crinkles.

Moving toward the crib, Twilight fought back another yawn. She was looking forward to her forty—maybe eighty—winks tonight.

Then two mechanical hands grabbed her by the shoulders. She jutted to a stop, brow furrowed as she turned to look at them. “Uh…”

“Now now, Twily,” the nursery said. “Be a good little filly and get changed properly.”

She narrowed her eyes, shrugging off the hands. “I don’t want a change, okay? Just let me go to sleep.”

Before she could take a step forward, the hands grabbed her sides and lifted her up. She was pulled away from the oasis that was her crib.

“Twilight.” The AI’s voice was stern, like a scolding from Celestia. “Don’t ignore your mommy.”

At this point, Twilight knew she was pushing some buttons. But she also knew she wasn’t in the mood to play around.

Unfurling her wings, she slapped away the hands. She fell less gracefully this time, ending up on her belly. Twilight wobbled to all fours, only for four hands to leap out and grab her hooves.

“Hey!” she cried, returning the the air. Her wings flapped, but couldn’t angle far enough to hit anything.

“That was very naughty of you, Twilight.” The machine berated.

“Let me go!” Twilight demanded. She put up a struggle against the arms, but it amounted to little.

“Naughty fillies need to be punished,” the machine declared.

It pulled her across the room, now not even aiming for the changing table. Turning her head, Twilight saw she was headed over to the stool across the room. Another hand popped free of the wall beside it, brandishing a large, wooden paddle.

Twilight groaned. She did not need this right now.

With a spark from her horn, she teleported. The hands holding her in place found their grip tighten around air. Twilight appeared just below them, a frown forming across her face.

Guess I set the levels wrong, she thought as her magic grabbed the four arms in the air. Maybe lowering the discipline would’ve been better? A smarter learning algorithm?

She could correct that in a moment, begrudgingly. It didn’t change the fact that her much needed rest was delayed. More hands appeared from the walls, ceiling, and floor, all moving towards her.

“Twilight, you’re being a very bad filly,” the nursery warned. She ignored it.

Despite how tired she was, Twilight’s magic caught every arm coming for her. Even the one carrying the paddle had made an attempt.

Normally spankings would be fun for her, but tonight was just not the night for it. Maybe in the morning she’d be more willing to indulge in the more fetishistic aspects of her nursery. As for now she just bunched all the wiggling arms in a pile.

That should be all, Twilight thought as she waddled to the control panel. She just wanted to shut the nursery’s AI off and hop in the crib for now. Come morning she could fiddle around with the settings all she wanted. The big red button above the monitor was the only thing standing between her and a good night’s sleep now.

Just to be safe, she counted up all the arms in her grasp. Thirteen, fourteen, fifteen, six… wait. She froze. Where’s the last one?

Just then she felt something cold slip around her horn.

The purple aura holding all the arms together fizzled out. Terrified, Twilight looked up. She caught the last hand pushing an thick metal band down her horn.

Her pupils shrank. Her heart pounded. The bundled up arms seized the opportunity to disentangle.

Wait… no! Twilight blinked away her shock, shaking her head. Where did it get… it shouldn’t have access to inhibitor rings in this room!

But she didn’t have any time to worry about that. All fifteen hands lunged for her.

With an “eep” of surprise, Twilight tried to remove her inhibitor ring before it was too late.

It was too late.

Her hooves made it just passed her chin before the arms reached her. Two hands snapped around each foreleg and forced them out. Twilight struggled against them, but couldn’t recover an inch.

Her hind legs were targeted next, each earning two more hands. All eight arms lifted her into the air now. Flapping her wings, Twilight struggled against their hold.

“No!” she cried. “Stop it!”

“I’m sorry, Twilight, but you’ve been a very bad filly.” Hands glommed onto her wings and sides, forcing her still. “And bad fillies need to be punished.”

“Wait!” Twilight pleaded. The nursery didn’t. It yanked her through the air, aiming once more for the stool near the end of the room.

Twilight looked back desperately. The failsafe button on the wall was definitely out of her reach now. And if she couldn’t break free then that meant…

I’m stuck. Twilight thought as she was laid across the stool. The paddle disappeared behind her and she gulped. Oh Celestia…

CRACK! squish.

“Ah!” Twilight flinched. Though the nursery swing was powerful, her poofy, poopy diaper absorbed most of the shock. But she could still feel it. And worst of all, she could feel her mess jostling about within her diaper.

CRACK! squish. CRACK! squish.

“Unf~” Twilight bit her lip. The paddling spread her mess around in her diaper, leaving no space clean. As much as it pained her to admit it, she loved it.

CRACK! squish. CRACK! squish.

The sensation sent her marehood quivering with each strike. As the warm mush spread, so to did a deep blush on her face.

CRACK! squish. CRACK! squish.

“Oooh! Ah-AH!” Twilight groaned as her libido kicked it. For a moment, it barely registered that all her limbs were being held down.

CRACK! CRACK! CRACK!

Things changed. After a few good whacks, her diaper had been flattened and the bulk of her mess escaped to less volatile areas. Now her padding wasn’t doing much to protect her.

CRACK! CRACK! CRACK!

“Ah~ A-Aaah!” Twilight still couldn’t deny the pleasure, but now it was mixed with pain. Her plot suffered a flurry of unprotected blows as the nursery continued what it thought was a well deserved punishment.

CRACK! CRACK! CRACK! CRACK! CRACK! CRACK!

“S-Stop it!” Twilight whined. Her butt was on fire, but her marehood doubly so. She was being pushed closer to the edge with each whack, but that couldn’t mask how much it hurt.

CRACK!

One last spank connected. Twilight’s plot stung as tears leapt to her eyes. It was hard to decide if she was more aroused or more in pain right now.

Nine is too high, she concluded, sniffling. Way too high.

Her resistance having faded, several of the arms holding Twilight in place retracted. Four still remained, one for each leg. Clearly she wasn’t trusted anymore.

“I’m sorry, Twily,” the machine cooed, back to motherly in an instant. “I promise you that hurt me more than it did you.”

She wanted to get off a sarcastic laugh, but only a whine came out. Her plot radiated with pain and her marehood cried out for attention.

Neither were getting relief though, as Twilight found herself lifted back into the air.

“Now then,” a much cheerier tone returned. “Let’s get you changed.”

“C-Can you take off my horn ring now?” Twilight managed through everything.

“Oh, I’m sorry sweetie, but clearly your magic has been acting up lately.” She got a consolatory pat for her trouble. “So I’ll just leave this on to keep that under control.”

Twilight clenched her jaw. Not that she expected that to work, but still. She was completely at the AI’s mercy without her magic and while in certain scenarios she could find that quite thrilling right now wasn’t one of them. Especially since it didn’t look like there was an end in sight.

But at least she was coming to understand how the nursery had gotten the inhibitor ring idea from. If it thought Twilight’s magic was in a state of flux that most young ponies experienced, the mothering program must have sought this out as a way to protect her from herself. But how it had access to them in this room was confusing. Maybe a bug in the programming? Did the AI overwrite her protocol to get it?

Twilight shivered at the thought of that. That was a worst-case scenario if there ever was one.

She was carried back to the changing table. After everything, she was still going to get a change. Though, at this point Twilight couldn’t complain. Her libido was all wound up from the spanking; she needed something to calm it down or she’d never get to sleep. And a good night’s rest was surely what she needed to be able to think her way out of this problem.

Not wanting to risk more spankings, Twilight played along with the machine as it set her down on the changing table.

Her forelegs were still pinned down for her change. The dirty diaper was peeled away, while extra hands fetched wipes.

Cold hit her undercarriage as the wet wipes scrubbed away ever last remnant of her mess. They were a soothing presence on her stinging backside.

A nighttime diaper—twice as poofy as the last—came to her waist. The familiar sight of Luna’s Cutie Mark decorated her rear now, marking this diaper as one from the Nighties brand. With a puff of foal powder and a dab of rash cream, it was sealed around her.

The fluffy padding toyed with her already excited marehood, but that desire was fading now. Exhaustion was creeping in once again, held at bay just barely by her surprise spanking session before.

With another yawn, she finally earned a giggle from the nursery.

“Let’s get my little Twily to bed.”

Finally, Twilight was taken to the crib. Her back met the soft mattress, head sinking into a plush pillow. Her legs were finally set free as the hands pulled a snuggly blanket over her body.

Though she was effectively a prisoner, bars and all, fear for her situation wasn’t keeping Twilight awake. Not even her sore plot made a difference. Already her eyelids were sinking, ready for dreamland.. The mobile above her spun, and her fading eyes tracked it round and round before fluttering closed.

Everything else about the nursery seems to be operating normally, came Twilight’s last thoughts. Even in the presence of the Sandmare she couldn’t stop thinking. I’m sure whatever glitch caused this will be worked out of its system by morning.

Come morning… it’ll all be fine…

I’ll be fine…

She hoped.

Author's Note

And here it is, folks: the first chapter of my longest fic ever. I teased this one way back in early July, but now we've finally begun!

When I asked a bunch of you guys about this, the consensus was pretty overwhelmingly 'Publish when you've got it' so that'll be the norm for this one. New chapters will be a little slow going for this one, but each update should be a pretty sizable one at least.

Hope you all are looking forward to more!
