Twilight sniffled and whimpered quietly. Her red bottom was sat squarely on the stool, being given no respite after the brutal lashing it had just received. Her oversized diaper helped, but a cushion could only do so much to assuage her stinging, burning cheeks.

She was stuck in time out, facing the corner while the many hands of the nursery scrubbed away the mess she’d made. Twilight knew that stepping out of line here would mean another round with the paddle. She stayed put and merely suckled on her pacifier.

Ideas ran through her head, but no escape plan she could come up with seemed viable anymore. The nursery was well equipped to handle her at this point, so unless she could free her horn she was stuck. But any plans for that were equally dashed. She knew the nursery was keeping a close eye on her, especially after that last escape attempt. If she even so much as touched the ring on her horn she could very well get another spanking session for that too.

In short, she had no idea what to do. Maybe, maybe, the nursery would leave her unattended for a moment and she’d be able to switch it off.

She snorted. With it’s mothering matrix maxed out? Unlikely.

At night the AI would go into a less active mode in order to recharge, process the days events, and calibrate itself. That would be about the only time she wasn’t going to be under constant scrutiny.

But she couldn’t wait until nighttime! She had to get out now. More of that dreaded paperwork was bound to pile up while she sat here doing nothing. Not to mention ponies would eventually go looking for her. While she doubted anyone would find her down here, she didn’t want to cause any worry. Not to mention she would not be looking forward to explaining where she was.

She shifted in her seat, plot radiating pain. Twilight whimpered into her pacifier and suckled. She also had to escape before she got spanked again.

Her marehood was still quivering from the last one. It nagged her while she tried to think, demanding release. It really didn’t help that her diaper was smushed right up against it. The padding rubbed her slit with each movement, sending shudders through her body.

Twilight shifted again. Her plot stung, but her marehood shivered. She moaned into her pacifier.

Maybe… maybe I should take care of this, she thought. I can’t be expected to concentrate on escaping while I’m all hot and bothered…

That thought wasn’t fleeting either. In fact, it stuck out as the one good idea she’d had so far. After all, she’d been teased since yesterday. And this was a room specifically built so she could take care of those urges.

It wasn’t like she needed a lot of convincing.

Another shift in her seat, another delightful rub of floof against her marehood. That tears it!

Her hoof dove into her crotch.

“Nn~” Twilight bit down on her pacifier. The barrage of poofy padding against her marehood was intense. It flooded her folds, soaking up the first juices from her already wet pussy. “Ngahh!”

She rubbed. Back and forth, slowly and deliberately. Her marehood grew hot and tingled as the padding brushed against it. The sensation was as incredible as it always was, and her constant edging lately only heightened her desire for more.

“Gah~ Ahh, ahh huhh!” Twilight picked up speed, digging deeper into the padding.

The sting of her backside didn’t feel so painful anymore. In fact, the memory of her spanks only made her more horny. The radiating pain was a turn on more than anything at this point.

“Oooh~ Oh Celestia,” Twilight moaned. She was getting close. Her pacifier fell out of her mouth as her gasps of pleasure grew stronger.

“Okay, Twily,” Hands suddenly wrapped around her body, gripping her below the shoulders once again.. “I think you can come out of time out now.”

The hands tugged her into the air, pulling her fore legs away from her crotch in the process. Twilight whined, kicking all four hooves in protest. “Wait, no!”

Her marehood ached as the pressure left. Her padding crinkled back into place, it’s fluffy interior leaving her bereft of a climax.

“Come on!” Twilight complained. Her legs kicked uselessly in the air. She couldn’t even bring them together to try to bunch up her padding against her her marehood. The diaper was just too thick.

All she was left with was a cloying set of privates and a feeling of frustration. After so much teasing already today, she’d just about had it.

“Aww, sweetie, you dropped your paci.” An arm reached down to chase the dropped device. Meanwhile the hands carrying her brought her around to face the rest of the room.

The nursery had done an admirable job cleaning itself. The white carpet still had a faded orange stain on it, but it was about as perfect as one could expect after what she had done to it. ‘If you weren’t looking for it, you could easily miss it.

Twilight also noticed the easel was folded and resting against the wall, unlikely to be played with again. She grumbled a little at that. Her failed escape attempt had cost her.

But if nothing else she was off her stinging plot. As arousing as the pain was, it didn’t take away from the fact that it was truly uncomfortable. Hanging in the air like this was probably the best thing for her butt right now. But it also meant she couldn’t finish rubbing one in, nor could she focus on escape.

The pacifier reappeared, shoving its way back between her lips. Twilight grumbled, but accepted it. Right now she couldn’t afford to get on the nursery’s bad side again; it could ruin her next escape attempt.

“There we go, sweetie.” A finger pushed the pacifier against her mouth, keeping it in place. Twilight rolled her eyes. She knew the AI wanted her to suckle, but she really wasn’t in the mood. Her tingling marehood was about the only thing she could focus on.

“Now let’s give that diaper a check, shall we?” A new hand reached for her crotch.

Twilight kicked. “I cwean,” she protested. Couldn’t the stupid thing just put her down already?

“Now now, Twily, don’t be so fussy.” More hands appeared, latching onto her legs and pulling them out even further than her diaper already splayed them.

Twilight swallowed. The nursery had her on a very short leash right now.

The hand groped her diaper. Padding leapt back against her marehood, and Twilight practically purred. Her folds were once again swallowed by floof. The lingering embers of her arousal sparked back into a raging fire.

“Mmmph~!” Twilight arched her back, hooves curling. The nursery continued thumbing the crotch of her diaper, checking for wetness. And right now, she definitely was. Just… not the kind of wet the nursery was expecting to find.

Fingers hooked around against the seat of the diaper, as the palm continued exploring her crotch. Padding rubbed against her, scratching that oh-so sensitive itch.

It wasn’t long before Twilight was back on the edge. Chewing on her pacifier, her eyes rolled back. She could feel an orgasm coming, and she found herself pleading that the nursery wouldn’t stop anytime soon.

She was so distracted by the diaper check that she almost didn’t hear the metallic taps coming from the otherside of the room. But when she did, her ears pricked up. Her attention locked onto the door across the room. The door outside. The door somepony was knocking on.

The nursery paused too, keeping a hand buried in her diaper, leaving Twilight perpetually on the edge.

“Hello?” Came an inquisitive voice from the other side of the door. Twilight’s pupils shrank. Starlight!

“Starwight!” She cried out. “In here! Helwp!” Her situation was lost on her. All of a sudden Twilight saw a way out, and that was all she could focus on right now. Even her libido was taking a back seat on this one, though barely.

“Helwp me!” she yelled again. It was no good, the room was still soundproof to the outside. Twilight was able to hear Starlight, but Starlight would only get silence, no matter what.

There was a pause, probably as Starlight decided what to do. For a moment, Twilight’s heart seized at the thought that she’d leave. But instead, the knob clicked and the door gave way.

Starlight walked into the nursery, eyes squinting at the harsh lights. She blinked everything into focus. “What is this—“ She froze at the sight of Twilight. “—place…?”

It was then that Twilight realized just how she must have looked. Held in mid air, pacifier in her mouth, diaper around her waist, and mechanical hand around her diaper.

“T-Twilight?” Starlight’s jaw was on the floor.

It took a whole femtosecond for the humiliation to set in. A blush spread from cheek to cheek, redder than her glowing flanks. She squirmed against the arms that held her, doing basically nothing. And the hand against her crotch… Never in her life did Twilight wish so desperately not to cum.

“It’s nawt wha’ it wooks wike!” Twilight insisted. She couldn’t even spit out her pacifier.

“Uh...” Starlight looked like she was struggling to form words. “R-Right…” She snickered, covering her mouth with a hoof. Her eyes were on Twilight’s diaper.

“I’m sewious!” Twilight cried, face burning. She couldn’t believe somepony had actually found her before she managed to escape. How was she supposed to explain this now?

She shook her head; that wasn’t important right now. She still had to get out of the nursery. “Starwight, push da—AaauUUOooh~” The nursery’s hand left her diaper, sending a shudder of pleasure through her body.

“Aww, hello there, little filly. Are you a new playmate for Twily?”

Starlight’s brow scrunched at the sound of the disembodied voice. “Uh, Twilight what was that?”

“Da—gah… uuh…—da nuwsewy,” she wheezed out. She was trying so desperately not to climax. Her situation was already hard enough to explain as is.

“And what’s your name, precious?” The nursery cooed.

“I’m Starlight Glimmer.” Starlight looked around, trying to pin point the source of the voice. “And who… er, what are you?”

“You can call me Mommy, Glim Glam.” Hands descended from the ceiling.

Starlight’s snout scrunched and she stepped backwards toward the door. “Uh… okay, this is getting pretty weird. I’m just gonna go—“

Twilight wrenched her head away from the hand on her face. She spat out her pacifier and screamed, “HIT THE BUTTON!”

Starlight flinched. The hands above closed in on her while she looked around. Finally her eyes fell on the control panel. She looked back to Twilight. “That but—?”

Two hands suddenly grabbed her shoulders.

“Hey!” Starlight shrugged them off. Stepping away, she only put distance between herself and the failsafe.

Twilight felt her stomach drop like a rock. She had a bad feeling about this. “THE BUTTON!” she screamed again. “JUST HIT IT! HURRY!”

“Now don’t worry, Glim Glam. Mommy’s going to take good care of you, I promise.” The hands reached for her again.

Starlight shot a glance from them to Twilight. “Okay, what the heck is going on here?”

Twilight kicked uselessly at the two hands holding her hind legs. It was clear Starlight wasn’t aware of the danger she was in. If she had been, she’d be slamming that red button like there was no tomorrow.

“It wants to treat you like a foal!” she cried. “You hav—MMMPHMMFF!” Her pacifier forced its way back into her mouth, cutting off her warning. Twilight couldn’t even spit it out; the hand kept it pressed in place with a finger yet again.

Starlight at least seemed to get the message. She backed away from the approaching hands, but new ones popped out from the wall just behind her.

Twilight tried warning her with muffled screams, but despite her thrashing Starlight didn’t see them. Instead she just stepped up to the control panel completely unaware.

But she still had time!

Starlight raised her hoof, ready to press the failsafe. Relief overcame Twilight. This nightmare was finally going to end. But then Starlight paused and that fantasy shattered.

She turned to a fearful Twilight. “Which button do I need to—?”

The hands got her.

Three from behind managed to get her sides and the base of her tail. Starlight flinched. When she turned around to look at them the other two from the front caught up to her and grabbed her forelegs.

“Stop it!” Starlight cried out.

“Mmmph! Mmrph! Mrrrhrrrhrr!” Twilight screamed. Red! How could she forget to say it was the freaking red button?

The hands lifted Starlight into the air. Starlight had other plans.

Her horn ignited, filling the room with a brilliant blue. In a flash she teleported out of the hands’ grasps. They were left floundering momentarily while their captive reappeared at Twilight’s side.

“Seriously, what is up with this thing?” She asked.

Starlight’s aura wrapped around the hands holding Twilight and ripped them away. Twilight plopped on the ground, yelping as her sore plot was introduced to the floor.

“Hmm, seems my little Glim Glam has the same problem Twily did,” the nursery mused.

Twilight stood, spitting out her pacifier again. “Red!” she cried, almost angry. “It’s the red button!”

“Geez, calm down,” Starlight said. Twilight was acutely aware that the hands were already regrouping. “You’re acting crazy.”

“Don’t get overconfident!” Twilight begged, pointing to the now ten hands approaching them. “And don’t waste time! We need to hit the failsafe and get out of here!”

Blue magic snapped around all ten arms, freezing them. “I’m pretty sure I can handle anything this nursery can throw at me,” Starlight replied with a smirk. She wiggled the hands in her grasp like they were toys. “Why can’t you?”

“Because—“ Before Twilight could point to her inhibitor ring, she froze. Right behind Starlight, a new hand was approaching, wielding yet another one of those accursed rings. “Behind you!”

Starlight didn’t even hesitate. She teleported reflexively, right before the inhibitor ring slipped over her horn. The hand dropped the band over nothing and it flopped on the ground.

Starlight ended up across the room by the changing table. Her magical hold extended to the eleventh hand when she saw it. Her smirk only grew.

“See?” Starlight called to her. A twelfth hand descended from the ceiling, a new ring in its grasp. “Nothing I can’t handle.”

Twilight’s body stiffened. “Look ou—”

Too late.

The ring slid over Starlight’s horn. It fizzled immediately, then sputtered out.

Starlight’s eyes went wide. She looked up, seeing the hand and touching the metal ring around her horn. “…Oh.”

The eleven hands she’d been holding were now free once again. They wiggled free from their clusters and zoomed toward Starlight. She tried to pry the ring off of her horn, but there was just no time.

“No!” she screamed as all eleven hands clasped onto her body. Starlight resisted, thrashing and flailing with all her might, but it was a losing battle. “Stop! STOP!” Starlight screamed.

Hands held down each leg, locking her firmly in place before moving her. Starlight continued her struggle as she was lifted into the air. It was impressive how little she was actually moving, despite using all her strength. She was set down on the changing table.

“There we go little one. No more of those magical oopsies anymore. Now let’s get you diapered up so you can play with Twily.”

“Let me go!”

Twilight’s heart sank. Starlight had been her best chance of escape, but now she was doomed to the same fate as her. And possibly worse, there was no way she wasn’t going to find out what this nursery was for now.

But then, Twilight realized something. She was free! Four hooves on the ground, and the nursery’s attention focused elsewhere. Her gaze shot over to the failsafe on the wall. It was completely unguarded.

Yes! Now was the perfect time to strike. Twilight scampered forward, almost tripping over the size of her own gait. She slowed to a waddle, but made headway.

“Hold on!” Twilight called out to Starlight. The pink unicorn screamed in response. She was kicking and squirming, as a diaper was set beneath her undercarriage.

Twilight reached the halfway point and kept going. She was so close! The failsafe! The open door! Freedom! She could just about cry.

So of course she was crushed when two more hands appeared before her.

She practically skidded to a halt, ears dropping. Was she about to be spanked again? She didn’t think her plot could take another beating, as much as the thought excited her.

“Don’t worry, Twily. Mommy hasn’t forgotten about you,” the nursery cooed. One of the hands reached back and nudged the door closed. Twilight watched the stairs behind it disappear with a thud. The other hand approached her, and she realized it was holding something.

Her pacifier, but upgraded.

A thick, rubber strap was attached to the guard. Twilight gulped.

“Since you keep losing it so much,” The nursery explained.

Twilight stumbled back and tripped. She landed on her diapered plot, sore flanks sinking into the padding with quiet screams.

The hands looped the strap around her head. She would struggle, but what was the point? All that would happen is another spanking. She couldn’t win against the nursery, not like this anyway.

With the strap against the back of her head, the nursery pulled the pacifier until the rubber was taut. The fingers released, snapping the pacifier into her mouth with a loud TWACK!

Twilight whimpered as the guard smacked her lips. The rubber nipple of her pacifier was back in her mouth, settling onto her tongue despite her best efforts.

“Bu—But I don’ wan’ my paci,” Twilight sniffled. The nursery scooped her up, giving her a pat on the head.

“Don’t worry sweetie, it’ll help you calm down.” One of the hands booped her nose. “Now don’t you want to play with your new friend?”

Twilight sniffled. Tears threatened, and she was tempted to let them loose. How could her situation keep getting worse and worse?

She was spun around, just in time to see Starlight be lifted from the changing table. She had a fresh diaper wrapped around her flanks, and an angry glare on her face. Only a few hands were taking care of her now; apparently the nursery decided she wasn’t all that dangerous anymore. Despite this, Starlight still swatted at the few that were around her.

Still too afraid to defy the nursery right now, Twilight just hung her head in shame. “O’tay,” she answered.

“Good girl!” The two of them sailed through the air, finally meeting up just above the playpen. Twilight couldn’t make eye contact with Starlight. Her face just cycled through shades of red as the other mare struggled against the hands.

“Put me down!” Starlight yelled. The nursery obliged, lowering them both into the playpen.

“Have fun you two!” The nursery chirped. A handful of hands hovered nearby. “Just call for your Mommy if you need me.”

Twilight bit down on her pacifier. She rolled on her flanks, trying to find an angle to sit on that didn’t sting. Her marehood was in anguish, so close to a climax only to have it ripped away in the end. And Twilight wasn’t exactly eager to return to it given her new playmate.

Starlight was stunned still for a second. But when that ended, hooves scrambled. She went for her horn ring first, but soon learned same as Twilight had that it was just to tight to take off by herself.

Her attention then turned to the diaper, hooves ripping at the tapes and legs kicking as she tried to get it off. She was tomato-faced as the garment crinkled with each touch. Her legs stiffened and kicked as she struggled with it, but eventually she managed to peel the tapes a little ways off.

“Wait!” Twilight said, finally stepping in. Starlight glared at her, but paused. “If woo twy to take it off idd’ll punish woo.”

Starlight huffed, but left her diaper alone. It crinkled as she tried to get comfortable, and she winced, no doubt unfamiliar with all the sensations of wearing a diaper. Her cheeks were pinker than usual by the time she finally managed to sit.

At least she only had one of the Sunnies. Twilight would kill to get out of her Nightie; if she’d had a smaller diaper back there she might’ve made it to the control panel in time.

Actually, she may get one soon. She could feel her bladder rear its ugly head again. She’d ignored it once before already, and that had only made it worse. Now it ached for release.

Twilight shifted in a poor attempt to cross her legs. She couldn’t afford to pee herself now. Not with Starlight watching. She was just going to have to hold it.

“What the heck is going on?” Starlight whispered, catching her attention. Her eyes glanced at the nursery’s hands, as if she feared eavesdropping.

Twilight bit her pacifier and twiddled her hooves. Eventually, she decided that she’d have to tell the truth. “I been stuck down hewe since wast night.”

“Okay,” Starlight said, as if that didn’t explain anything. “But what is “here”? Why were you down here in the first place? And… oh yeah, what the heck is going on?”

Twilight chewed her paci, dreading this part.. “O’tay… but, pwease don’ get mad at me.”

Starlight thought about it for a moment. “Alright…”

Twilight sniffled again. “And… pwease don’ waff at me.”

“Alright.”

Twilight took a deep breath. She really wished she didn’t have to do this with the pacifier, but she didn’t have much of a choice right now. “I… I buiwt dis nursewy. For myself.” Her lips twitched.

Starlight blinked, processing. “Okay…”

“A-And… wast night I was tiwred. So I came down hewe to… wewax. And I got stuck.”

Starlight nodded, but her brow was furrowed. “How?”

Twilight swallowed. “I pwogwammed the nursewy to take care of me, but it wen’ too far. Now I can’ stop it unless I hit da wed button.” She pointed.

“You can’t just tell it to stop?” Starlight asked.

Twilight shook her head. “I nevah pwogwammed voice commands. It… it was a wot of wowk and I jus’ wanted to…” she sniffled and wiped her eyes. “I nevah needed dem untiw now.”

“Right...” Starlight’s voice was straining to stay even. She could see Twilight’s face was even more flushed than her own. “Why did you even want something like this?”

Twilight’s stomach was all up in knots. “I…” She squeezed her eyes shut, turning away. No, she couldn’t explain it to Starlight. Hadn’t she been humiliated enough already? Twilight just resorted to suckling on her pacifier, hoping the subject would change.

Sensing her discomfort, Starlight just sighed. “So, to get this straight, you made a program to baby you, lost control of it, and now we’re both stuck in a nursery that’s going to treat us like foals for… how long?”

Twilight bit her pacifier. “I-Indefinetwy.”

“Indefinitely,” Starlight repeated, sourly. “That’s just… great.”

“I’m sowwy!” Twilight cried, nearly ready to burst into tears. “I nevah meant for woo to get caught up in dis, I sweawr!”

“I believe you,” Starlight said, trying to calm her. “Seriously. I bet this is the last thing you ever wanted anypony to see.”

She sniffled and nodded. “How did woo even know I was hewe?”

“You left that bookshelf-door thingy open,” Starlight said. She forced a laugh. “Might wanna be more careful next time.”

“Yeah,” Twilight sniffled.

“But it’s a good thing you weren’t, cause now I can help you get out of here,” Starlight told her, smiling.

Twilight blinked back tears. “W-Woo not gonna make fun of me?”

“I don’t exactly have a lot of ground to stand on right now,” Starlight gestured to her diaper. “Thanks to this stupid thing.”

“Heh, yeah.” Twilight managed a smile behind her guard.

“But trust me, once we get outta here you’ve earned a boatload of teasing,” Starlight smirked.

Twilight furrowed her brow, but couldn’t exactly deny it. She’d gotten Starlight trapped in here after all.

“Now come on,” Starlight pushed herself up and offered her a hoof. “Let’s go press that button.”

Twilight reached out her hoof, but hesitated. She had a feeling Starlight still didn’t understand the gravity of their situation. She’d yet to be at the receiving end of the nursery’s spanks.

Still, she took that hoof. Starlight’s determination was a life preserver after a morning spent drowning in hopelessness. It helped that she seemed to be understanding too.

“Come on.” Starlight toddled over to the play pen’s wall, face flushing at her infantilized walk. She reached up to the top of the mesh prison, ready to hop over the edge.

“Wait!” Twilight called out. Starlight froze. “If you try to leave it’ll stop you.”

Starlight frowned. “Well, we have to do something. Do you have a plan?”

“Weww…” Twilight bit her lip. She still couldn’t think of anything. The nursery had every angle covered and every advantage. Even exploiting its weaknesses hadn’t worked, as her plot could attest. “Maybe we shouwd just stay put and wait for a better oppowtunity.”

Starlight furrowed her brow. “Look, no offense, but I’m not staying a second longer in diapers than I have to. I’m gonna need more than a ‘maybe’.”

Twilight chewed on her pacifier. This was the first time the AI wasn’t constantly coddling her. Would they really get a better opportunity than this? Maybe she was just too fearful of another spanking.

Her plot whimpered, making a good argument for why she should be.

Twilight shook her head. No, they weren’t going to make any progress just waiting around. It would be better to try. Even a failure would be preferable than lying down and accepting her fate. “O’tay, wet’s go.”

“Now you’re talking.” While Twilight waddled over to the edge of the play pen, Starlight hopped up. She managed to get a single hind leg up on the edge before the hands whirred to life.

“Uh oh, is somefilly getting antsy?”

It grabbed up Starlight pretty quickly. Twilight winced, preparing for retaliation, but it didn’t seem like the nursery was all that upset.

“Here, let Mommy play with you a bit.” The nursery set Starlight down, but it’s hands didn’t leave her. Instead it picked up a rattle from the scattered foal paraphernalia around them and started shaking it in her face.

Starlight gave the nursery a disgusted look, but when she saw Twilight she motioned for her to keep going while she struggled against the arms around her.

Twilight gulped, nervous enough already for what might happen. She reached up to the top of the playpen and grabbed on.

Nothing happened.

Taking a deep breath she brought up her hind leg. It was a struggle with her poofy diaper butt working against her, but she managed to touch her hind leg on the edge the way Starlight had.

Nothing happened.

That was a surprise, considering Starlight had only made it this far. Twilight looked around to make sure no hands were coming for her and somehow none were.

She kept going, pushing herself up the rail. It wasn’t easy with her diaper in the way, but Twilight managed to jump up and roll over the top of the playpen.

“Oof!” She plopped down on the carpet outside. Her bladder almost released then and there, but Twilight barely managed to hold it back.

She’d actually made it.

Before getting up, she looked around. Only three of the nursery’s sixteen hands were active. They were still busy playing with Starlight, despite her best struggles.

Twilight pressed her lips together. Odd. Why were none coming for her? It’s not like there weren’t hands available.

“Twilight,” Starlight cried. “Go!”

“Mmph!” Twilight scrambled to get her footing. She couldn’t waste this chance!

It would take too long to stand, so Twilight just crawled. It was actually easier with her diaper anyway. Less chance to trip this way.

She scooted across the carpet. It was painfully slow, but better than nothing. The whole while, Twilight still couldn’t shake the idea that something was wrong. Why wasn’t she being pursued?

Sure, it wasn’t like she could complain. With the failsafe in sight, it felt like they might actually escape this time. But it was just… too easy.

“Hmm…” Twilight suckled as she thought. What was going on here?

Lost in thought, her hoof bumped into the plastic training potty. Twilight barely paid attention to it, and just kicked it out of the way.

“Oh.”

She froze, hair standing up on end. Hands appeared nearby. She was spotted, and still too far from the button to do anything.

“Mmm!” she squeaked in fear. Now she was going to get it! Another spanking for sure.

“Twily, what are you doing out of your playpen?” The nursery asked. So it had only just now noticed her.

“I sowwy,” she managed, trying to sink into the floor.

A hand picked up the training potty she’d kicked away and set it upright. “Aww, did you want to use the potty like a big girl?”

Twilight chewed her pacifier. Words stumbled around in her mind and died at her tongue.

The hands finally approached her. “Well you should have just told your Mommy instead of leaving your playpen, silly filly.”

She let out a sigh of relief. If it was using nicknames then it wasn’t angry with her. The hands grabbed her, but she didn’t resist. If it was just going to take her back to the play pen then there was no need too.

It didn’t take her back to the playpen.

Instead, Twilight was in the air for a whopping second and a half before her diapered bottom met the training potty. Her padding crinkled to make room for the plastic seat. The hands holding her didn’t leave, instead opting to keep her steady on her new chair.

“Okay sweetie, go ahead and go potty!” The nursery encouraged.

Twilight paled. It wanted her to… Oh no.

She shot a glance at Starlight, who was definitely looking at her. Even at this distance Twilight could see a brow climbing up that pink forehead.

Her ears flopped down. Did she have to? She could feel her bladder ache. It was nearly full, but it wasn’t like she couldn’t put this off until she and Starlight escaped, right?

Except, was the nursery even going to accept a clean diaper here? It seemed to think Twilight had left that play pen just to use the potty. That might be the only reason she was getting leniency right now. Her butt still stung from the session earlier, not helped by the forced seat she was taking; she didn’t want another lashing right now. Or ever.

Twilight mulled over her options, suckling her pacifier in thought. What could she do?

“Aww, is somepony having trouble with her potty training?” The nursery cooed. “It’s okay that you’re not a big girl yet, Twily.”

She grunted, but her cheeks flushed. Even in a situation like this she could help but enjoy being treated like a filly on some level.

Her bladder complained loudly. It seemed focusing on her need to go wasn’t helping. Twilight whined into her pacifier and slumped.

Maybe… Maybe I should just go, she thought. Afterall, a change into a smaller diaper would only help right now. Her stupid Nightie had kept her from escaping properly how many times now?

If only she didn’t have an audience. With Starlight right there, Twilight could do nothing but hesitate.

“There there, sweetie.” The nursery stroked her mane. “Just take your time.”

“Mmmm!” she groaned. Great, it was going to keep her here until she peed herself, wasn’t it? Well, in that case…

Twilight shifted on the plastic seat, trying to get more comfortable. She looked to the ceiling, unable to meet Starlight’s eyes. If she was going to have to do this, might as well just get it over with.

“Mmmm…” Twilight relaxed her bladder. It was so second nature now that she didn’t even have to try.

Hissssss

Twilight winced. In the quiet nursery, there was no avoiding that noise. Starlight definitely heard it, but Twilight didn’t look. Her face still flushed anyway, and ears flopped down. Her focus remained squarely on the ceiling.

Warm pee leapt into her diaper. It met up with a dam of padding ready to soak it up. Within seconds the fluffy interior became damp. Seconds more and it was soggy.

Twilight’s hind legs stiffened at the sensation. Warm, wet padding now tickled her pent up marehood. She could feel her libido revving back up at the slightest graze against her diaper.

“Mmm! Mmmm~”

Despite instinct, Twilight managed to hold her hooves away from her crotch. A feat that only grew harder the longer she peed.

Her diaper kept getting soggier as the wetting continued. As thick and fluffy as the Nightie was, it was almost ill equipped to handle the flood Twilight had unleashed on it. The padding became heavy with how much it was absorbing. New pee was forced to spread out and find drier corners to pollute.

Twilight could feel the warm stain expand. First along her inner thighs, then down by her plot to say hi to her cheeks. The damp sensation was soothing against her aching butt, and she had to hold back a moan. Against her better judgement she glanced down to check to damage. Surprisingly, her Nightie looked clean and dry on the outside, even though she knew that wasn’t the case.

Well… it is really big.

Her steady stream slowed until it was a mere dribble. Twilight breathed a sigh of relief now that it was over. She felt so much better.

She shifted atop the plastic potty, feeling her diaper slosh around. Her face burned a deep red, but it was her marehood that was really on fire. The sensation: warm, wet, padded… it was all a little much to handle right now.

Her twice-teased libido begged for a third-time's-the-charm scenario, but Twilight couldn’t obliged. Not in front of Starlight, at least.

Twilight looked up to see how her friend was doing. Starlight had turned away to give her a modicum of privacy, but the tips of her ears were a fiery red. She’d definitely heard every last drop.

Twilight’s cheeks were going to melt right off if her blush grew any hotter. She chewed her pacifier while holding back a moan.

Today can’t possibly get any worse.

She sat for a moment, waiting for the hands holding her down to free her from the training potty. The nursery made no attempt to. The only hands active where the ones still shaking the rattle for Starlight, while the AI cooed at her.

Twilight frowned. What was going on? She’d peed herself; surely the nursery knew that. But it almost seemed like it was ignoring… her…

Wait a second. A light bulb went off over her head. Is that why…?

It must be! The nursery was having trouble looking after two fillies at once. It made sense; it was so used to caring for just her, and with it’s learning algorithm at a four out of ten there was no way it could have perfectly adapted by now.

This could be how they escape!

“Mmm! Mmmph!” Twilight yelped into her pacifier. Her eureka moment was so powerful she completely forgot her situation. “Oh… wight…”

Hands gripped her side, and a soggy diaper gripped her hips. She’d have to fix these first.

The nursery still wasn’t paying attention to her. That, or it was waiting for her to call for it. For “Mommy”. Twilight groaned. Guess she’d just have to say it.

“I…” she blushed. Starlight cocked her head in her direction. Twilight slammed her eyes shut. “I made a peepee!”

Silence. Twilight could feel nothing but the burn of her cheeks and the wet padding against her hips. Then, finally…

“Aww, did wittle Twily finally use the potty-wotty?”

She cringed. For a moment, Twilight opened her eyes. Instant regret; she locked eyes with Starlight.

“Y-Yes,” she struggled to say.

The hands holding her sides jerked upwards. Twilight was carried into the air, as a new hand reach down for her...

“Wait!” Twilight cried.

The hand grabbed her crotch. Wet padding jumped into her marehood. Her already desperate privates now went for round three with the diaper. And it was good.

Twilight could fight back a moan that escaped her paci. It dropped the room into another deafening silence, save the sounds of the nursery fondling her wet spot.

squish. squish. squish. squish.

Starlight had undoubtedly heard. She burned some holes in the opposite wall, flopped ears a bright red.

But even that flush couldn’t compare to Twilight’s. Her face wasn’t even purple anymore, just a mishmash of pinks and reds that only dipped into deeper shades as time passed.

Finally the fingers withdrew, leaving Twilight’s marehood bleating for more. She took deep, sharp breaths just trying to calm down. Sooooo close… but she couldn’t let herself cum. That would create an awkwardness singularity she and Starlight wouldn’t never escape from, let alone this room.

“Looks like my little Twilight is all wet,” the nursery teased. It booped her nose. “But still not quite ready to use a big girl potty.”

Twilight grumbled a little as the nursery carried her over to the changing table. At least she’d be freed from this cloud of a diaper soon.

The nursery laid her down on the cold plastic of the changing table. Twilight shivered at the touch, but got used to it quickly. The routine of changing diapers commenced, with four hands on duty.

Twilight looked to the ceiling while supplies were grabbed and her tapes undone. Under normal circumstances, she’d be having a blast right now. In fact, on some level she was enjoying herself… she guessed. After all, it was hard for diapers to not be fun for her. But that didn’t mean she should even try to enjoy herself. She had to shut the nursery down, for her sake and Starlight’s.

She groaned into her paci-gag. Sweet Celestia, Starlight knows now! She hadn’t stopped to consider just what that meant before. Her deepest, darkest, most humiliating secret was on the table now. What was she going to do? Starlight wouldn’t tell anypony, right? Probably not, but this was still the type of thing that would prevent them from making eye contact for a long, long time. Was their friendship in jeopardy?

Twilight whined. Of course it was. If she’d gotten stuck in somepony’s fetish dungeon against her will, that would certainly put a damper on the magic of friendship between them.

Great. Twilight bemoaned as her soggy diaper was peeled back. Phenomenal even. Just perfect!

Her privates shivered at the rush of cool air. Her quivering marehood almost couldn’t take it.

Wipes rushed in and cleaned her up, while the diaper was tugged away. The hands operated efficiently, balling up the diaper and tossing it while unfolding a new one. Twilight found her legs lifted and a new slab of padding pushed underneath. Powder soon followed, before her plot met the new, plush interior that would soon hold it.

In the end, she barely had any time to get used to life without a diaper. Her new one was hugging her hips in no time.

She at least breathed a sigh of relief at the sight of the Sun Cutie Mark at her crotch. The new, slimmer diaper finally let her gait regain some lost ground. Her legs were still spread, of course, but it was much more manageable this way.

“There we go, you cutie-patootie.” The nursery pinched her cheek. “All clean and happy.”

Twilight blushed. Only one of those is true! she insisted.

But the nursery couldn’t hear that, nor would it have cared. It just lifted her up and turned her around back to the room. Twilight let all four legs dangle; she knew resisting this part was useless.

When her attention turned back to the nursery, she caught sight of Starlight. The mare must’ve seen an opportunity because she was back to climbing out of the playpen. The arms formerly entertaining her were still nearby, limply holding a rattle.

Twilight lit up, realizing her theory was true. The nursery still couldn’t divide it’s attention well. Though, for how long that would work, she had no idea. It was slow, but it was still learning. They may not have this advantage for much longer.

“Oh, dear,” the nursery gasped. “Glim Glam, are you trying to get out again?”

Twilight whimpered. Now it’s focus was back on the playpen, apparently.

Starlight froze, three legs on the edge. She looked to Twilight, wondering if she should make a run for it. Twilight shook her head; she didn’t want to risk Starlight getting any spankies right now.

Starlight huffed, but her legs came down. “No,” she grumbled.

“I think my little Glim Glam’s a little anxious. Maybe she just wants her pwaymate back,” the nursery teased. It plopped Twilight back into the pen. Square one again. “Have fun, sweeties!”

The two locked eyes before they darted down, then away. Now “alone” again, there was a whole new elephant in the room.

Twilight bit her pacifier. She couldn’t believe she had to pee herself in front of Starlight! And worse yet, the moan… there was no explaining that away.

Starlight was well aware, just based on the look on her face. The two just sat there, exchanging shades of red with their cheeks.

“Well,” Starlight finally broke the silence. “Did you think of a new way out of here? Cause it doesn’t look like just running for it will do the trick.”

They were changing the subject. Thank Celestia.

Twilight nodded. “I tink so.” Her tongue rolled around the pacifier and she silently cursed this stupid lisp. “Da nuwswey’s nawt good at handwing two fiwwy’s at once. At weast for now.”

“So if one of us distracts it,” Starlight realized. “The other can hit the failsafe!”

Twilight nodded. “Bu’ we don’ habb wong. It’ww figure it ouwt eventuwawwy.” How long exactly did they have? A few hours? All day? “We weawwy need to bweak ouwt by night. If we’re put to bed it’ww go into nighttime mode and pwocess evewyting. Den we won’ stand a chance in da mowrning.”

Starlight took a moment to translate in her head, then nodded. “Okay. It’s not like I was planning to stick around that long anyway.” She shifted uncomfortably in her diaper, trying to cross her legs.

Twilight’s eyes widened. “Woo hafta go to da baffwoom?”

Starlight cringed but shook her head. “No! No… I’m fine. I just meant we gotta get out of here before…” She bit her lip in thought. Then a light bulb went off. “Trixie! I invited her over today and I gotta meet her by noon. We need to get out of here before then or she might go looking for me.”

Twilight decided to let the bathroom remark drop there; it wouldn’t be the best thing to keep bringing up. “O’tay,” she said. Besides, they had a pretty heavy deadline now. The last thing they needed was Trixie, or Spike for that matter, poking around and finding them like this.

“In dat case, we need a pwan,” Twilight said, one already taking hold. Starlight smiled, knowing the look sprouting on Twilight’s face.

This next attempt would surely succeed. It had too.
