Warning: This does go to some naughtier, more adult places than most of my stories do, as there is a decent chance future Matti stories will as well, so be aware!

Matti swallowed, turning slowly to face Ms. Emily's desk again, yanking her thumb out of her mouth so she could grab at the hem of her dress's skirt with both hands, trying in vain to hide what had happened, even though she knew Ms. Emily had to have seen the whole display, and that the dress was nowhere near long enough. It hadn't been for just the diaper, and there was no way it could be now that she'd used the diaper.

"N-Nothing," she fibbed anyway, shuffling her feet nervously. She knew it was pointless, yet the truth was too humiliating for her to admit out loud.

"Nothing?" Ms. Emily raised an eyebrow. "I think something did, don't you? So, what was it?"

Matti shrugged, staring down at the floor intently. "I-I dunno."

"You don't know, huh~?" Ms. Emily's tone made it clear she wasn't buying that for a second, that she was just playing along, like she might with a bashful little kid. "You'd better let me have a look, then."

Matti gasped. "N-No!" she shook her head frantically. It was bad enough Ms. Emily had watched her do it! She didn't want to get closer to the woman, let her see the damage she'd done up close!

"Yes," Ms. Emily replied sternly, pointing at the floor beside her chair. "You march yourself over here right now, young lady, or we'll have to add another spanking to your discipline regimen! One now, and one after everything else!"

"Y-Yes, ma'am," Matti sniffed, shuffling around the desk, her cheeks darkening further still as she felt the mass in her pants shift and squelch between her legs with every step, a constant reminder of what had happened, and what Ms. Emily was about to witness.

"Turn around," Ms. Emily ordered when Matti had arrived, waiting for the girl to slowly turn, exposing her lumpy bottom. Matti whimpered, feeling her skirt being raised up, then let out a squeal as the seat of her diaper was given a pat. "I think I've solved the case," Ms. Emily teased, tugging out the waistband of Matti's diaper, then running her hand along the whole back of it.

Out of nowhere, Ms. Emily picked Matti up, setting her down straddling her knee, facing Ms. Emily. Matti let out a tiny, shocked sound as her backside sank into the mushy mess for the first time, getting the full impact of what, exactly, she'd done, and how truly infantile it was. "You, young lady," Ms. Emily told her, lifting the girl's face by the chin when she attempted to look down and avoid eye contact, "filled your little diapers to the brim."

"I-It's not my fault!" Matti insisted, squirming in place, diaper squishing beneath her. "Y-You made me eat all that oatmeal, a-and..."

"No, sweetie," Ms. Emily told her. "I'm not mad at you! You're such a good girl! That's exactly what you're meant to do! In fact, I think we may need to feed you that for every meal from now on!"

"E-Every meal?!" Matti squeaked. The oatmeal had tasted so icky, that was the last thing she wanted. And if it affected her like this every time, she'd be spending all day filling her diapers! The thought was incredibly humiliating, but also, embarrassingly, kind of hot. Being forced to eat that bland, mushy paste over and over for the sole purpose of making sure she kept her diapers messy, her confidence it her ability to use the potty like a big girl quickly eroding, since, as she'd discovered already, the oatmeal, at least that much of it, was too much for her system to handle...

It was almost like Ms. Emily knew she was thinking it, too, because she chose that moment to begin bouncing Matti on her knee, the girl gasping at the sudden movement, the redness in her face intensifying as the contents of her pants squelched and spread beneath her, they, and the padding of her diaper, brushing against Matti in a way that was absolutely mortifying and almost equally electric, sending a jolt straight up her spine, her toes curling in her heels, and an involuntary moan escaping her lips.

"It's very important to keep little girls like you regular," Ms. Emily told her, continuing to bounce her leg. "Don't you worry, though, we'll mix in some nice pea, or banana, or prune baby food now and then to make it interesting."

All of that was just going to fill Matti's tummy more, and, in turn, make her fill her diapers more. And if that led to her having the chance to feel this way, Matti wasn't sure she minded too much. Never in her life had she felt anything like this, or that even came close! She knew that this was serious, and she needed to find a way out of this, but she couldn't help herself. Her feet dangling on either side of Ms. Emily's leg, she began trying to move in time with the bouncing, to rub against the woman's leg, every success making her feel like she was vibrating with pleasure.

Ms. Emily smiled down at her, the constant surveillance making Matti self-conscious, but not enough to be able to convince herself to stop. "Aww, do you like that, sweetie~?" she asked after a few minutes.

Matti knew she should deny it, but she also knew it was pointless, that her actions were betraying her. She nodded, blushing and nibbling her bottom lip as Ms. Emily reached up, wiped off a line of drool that had started to emerge from the corner of the girl's mouth. Already, she was thinking about the playroom again, remembering all the giant stuffed animals she'd seen in there. It might not be quite the same with an inanimate object, but the relative privacy might make up for that, and she could hardly wait to find out, to fill her next diaper and find a fluffy companion to hump.

"I hope you are having fun," Ms. Emily continued, "but if you make squirties in your diaper, I'm afraid I'm going to have to lock up your princess parts for a long, long time."

Matti's eyes widened, hoping that this was a joke. It seemed like Ms. Emily wanted her to do this! Why would she punish her for it?! She swallowed, squirming in place as she looked into the woman's eyes, seeing no indication there that she wasn't being serious, though there was definitely some amusement there as she watched Matti trying to stop, only to be lured back in with every successive knee bounce, helplessly horny despite having been told the consequences.

"That's not something good little girls do, is it~?" Ms. Emily asked. Matti shook her head. "Big girls don't either, not like this. A big girl would never feel this way in a messy, stinky diaper!"

"I-It's not my fault!" Matti groaned.

"Nothing is, is it, Mathilda?" Ms. Emily taunted. "It's not your fault you pooped your pants, it isn't your fault that you're turning a perfectly innocent little horsey ride into something so dirty and perverted..."

That wasn't what was happening! Matti didn't know how, but Ms. Emily was definitely doing something more, not just a simple knee bounce! But how? And what? There was no evidence of that whatsoever, of there being anyone else to blame except for Matti's own dirty mind.

"I'm serious, Mathilda," Ms. Emily told her, not pausing, or slowing, the pace of her bouncing. "You'd better stop it right now! I want you to have fun, but I have to show you that there are consequences for your actions, and I know you aren't going to like that! So, go on, Mathilda. Stop it~."

But Matti was too far gone. She moaned loudly as a wave of pleasure washed over her, her back arching, toes curling, body shuddering. "O-Oh, my God!" she gasped, struggling to catch her breath.

"Oh, Mathilda," Ms. Emily shook her head, brushing a few stray, sweaty strands of hair away from Matti's face. "You're a virgin, aren't you?"

The question came out of nowhere, taking Matti by surprise, that, and the wave of euphoria she was riding keeping her from even thinking about lying. "Uh-huh," she admitted. In all honesty, she'd never even been on a real date. The whole experience made her nervous, from being expected to dress up, to what she was expected to do at the end, and trying to figure out what that was so she wouldn't be considered either a total prude, or a complete slut. "I-I've never... That was... Wow..."

"I had a feeling," Ms. Emily smirked, picking Matti up and setting her down on her floor, the girl's knees still not recovered enough, sending her falling to the floor to her mushy bottom with a squeal, immediately starting to squirm, searching for a return to the sensation she'd just experienced. "That's exactly why I have to do this," she said, opening up one of her desk drawers. "When little girls like you feel big girl feelings like that, that they aren't ready for, they just can't control themselves. This is for your own good."

Matti whimpered, seeing the metal contraption Ms. Emily produced, and, without thinking about where she was, and who she was in front of, reached down, trying to rub herself through her double diaper, barely able to feel it through all that bulk. Ms. Emily calmly grabbed her hand, pulling it away from the diaper and pulling Matti to her feet by it, leaning forward to fasten the belt around Matti's waist.

"You see~?" she asked. "You need this, Mathilda. You can't help yourself."

Matti sniffed, feeling a tear rolling down her cheek as she heard the click of one lock, and then another, as the belt was secured snugly over her diaper, the crotch strap snug against the padding, ensuring no naughty sensations would be able to get through to the other side. "H-How long?"

"Oh, a long, long time," Ms. Emily promised gleefully. "Until I think you're ready. Once I decide you're ready for a clean diaper, I'll put this back on underneath it, and lock it up nice and tight again, and then who knows? I might just wind up losing the key, especially if you're not a good little girl for me, and do whatever I say."

It wasn't fair! Matti had found something incredible, no matter how embarrassing it was, and how she knew nobody back in her real life would understand, and she'd already had it taken away from her! So much of what she'd heard about in diaper stories hadn't quite lived up to her imagination, but this had blown well past any expectations she'd had, whether that was somehow thanks to Ms. Emily or not. And now, she wasn't going to be able to enjoy it again for God only knew how long!

It was so cruel, too! Ms. Emily had made sure she knew just how good a messy diaper could feel, right before taking it away, while also ensuring, with Matti's diet, that she'd be having plenty more of them! Every time, she'd think back to this one, and wish she could do it again, and she wouldn't be able to! She'd just have to sit and squirm in her poopy pants like any other toddler, waiting for a grown-up to decide to change her.

"Aww, are you crying because I won't let you make stickies in your stinky diapers anymore~?" Ms. Emily teased, making Matti aware that the one tear she'd noticed had started to multiply. The woman was phrasing it to make it sound as bad as possible, though it was, indeed, pretty humiliating, but that didn't stop Matti from nodding, admitting it.

"Oh, Mathilda!" Ms. Emily declared suddenly, clapping her hands. "You clever little girl! Maybe I was wrong about you! I thought you were being naughty, but you were just demonstrating what a baby you already were by behaving that way, weren't you? I guess I'm the silly one, thinking that you need to be disciplined for just being yourself! Honestly, I ought to just let you go home, because there's nothing more for me to teach you here! You're already the perfect baby!"

"Wh-What?" Matti sniffled. "N-No, I'm not! I-I'm a big girl!" She knew she wasn't supposed to say it, but she couldn't help herself.

"Are you?" Ms. Emily asked simply, eyebrow arched.

Matti gulped. "Y-Yes."

Ms. Emily crossed her arms. "Is that what you WANT to be?"

"Y-Yes, of course!" Matti replied perhaps a bit too quickly.

"Is that why you're failing all your big girl glasses?" Ms. Emily pushed the report card towards Matti, who quickly grabbed it, trying to hide it behind herself. "Is that why you messed your diaper?" Matti had a much harder time disguising that, though she made one more attempt with her useless skirt. "Why you had your little orgasm in it? Is that what big girls do, Mathilda?" Matti didn't know how to answer that, or, rather, didn't want to. Ms. Emily turned back to her desk, this time producing an oversized pink bonnet, leaning forward to tie it around Matti's head. "You are the purest, sweetest, most perfect little baby I've ever seen, and I've seen a lot."

"B-But I'm not!" Matti shook her head, toddling away from Ms. Emily, trying to think straight. There wasn't far for her to go in the woman's office, however. "I-I didn't even know about any of this until a few hours ago!"

"Such a natural!" Ms. Emily purred. "All it took was one little push, wasn't it? That's how it always is with babies like you. One tiny suggestion, and they're happy to leave their grown-up selves behind and go back to what they really ought to be."

"Th-That's not..!" Matti grumbled, pausing as she saw the picture book on the floor, where it had fallen out of her hands when she'd gotten out of her seat. She bent over, picking it up, looking at the picture of herself on the cover, a happy baby. "W-Well, if I am the perfect baby," she threw the words back in Ms. Emily's face, even as acknowledging them made her head spin a little, "then I wish you would let me go back home!"

And then, all of the sudden, she was outside, Ms. Emily's office gone. She gasped, looking around, for a moment thinking that everything was back to normal when the sides of the bonnet were no longer blocking her view, before the smell of her diaper reached her nose. Thankfully, the chastity belt was gone, at least, but the rest of her outfit remained, as she stood right in the middle of her college campus.

"No!" she gasped, her eyes widening, her skirt feeling shorter than ever. Thankfully, it was night, even darker and later than it had been when she'd left campus what felt like ages ago, but anyone could still appear at any moment. Or there were security cameras, or... She shook her head, stomach churning at the many ways she could be found like this.

That wasn't the least of her problems, either. She had nothing, except the report card and the picture book. The bag she'd taken was gone, along with her car keys, her student ID, her phone... Everything! Some of it was back at the school with Jasmine, others on the floor of the daycare's playroom, but no matter where it was, all that mattered was that none of it was there, with her, where it could help her.

"This can't be happening!" she whimpered. How was she going to get out of this?!

Her first instinct was to head back to her dorm, of course, but, thankfully, she stopped short. Her dorm was the smallest on campus, full of only single rooms, and, while she loved that normally, it also meant that everyone there was at least familiar with her. If they spotted her, they'd recognize her right away.

The better option was to go to one of the bigger dorms, try to hide and wait for someone to go in and hope she could catch the door before it closed and locked behind them. It was late enough now that most of the big parties would have died down, she hoped, and anybody filing it was probably coming from a smaller one elsewhere on campus, and would hopefully be too drunk to notice her slip in behind them.

It did take a bit of waiting, crouching in the bushes, at once both grateful to be free of the chastity belt, and frustrated with herself for how much she wanted to see if enjoying herself in her messy diaper would feel the same when she did it on her own, or if Ms. Emily really had somehow been doing something more to her that she hadn't been able to see. Now was absolutely not the time for that! She couldn't afford to get distracted, or to make any noise! But the temptation was strong anyway.

Thankfully, she eventually saw a girl stumbling down the sidewalk, and, thanks to having taken off her heels so she could move faster, was able to run up to the door and catch it before it latched shut. She crept inside, making a bee-line for the stairs down into the basement, where she knew the laundry room was. She held her breath as she peered into all the dryers, praying that at least one person would still have their clothes in there.

They had. The t-shirt was huge on her, as were the sweatpants, but beggars couldn't be choosers, and the sweatpants had a drawstring, so she was able to make them work. The basement bathroom was even empty, giving her the privacy she needed to clean herself up as best she could and throw away the diaper and babyish outfit.

Most of the people from her dorm weren't big on going to parties, so it took longer for someone to show up there. On the plus side, she didn't have to creep around to avoid being seen, as they were happy to let her in with them. From there, all she had to do was knock on her RA's door to be let into her room, and, finally, her long day was over.

~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~

The chastity belt hit the floor of Ms. Emily's office first, the bonnet drifting down gently on top of it as the djinn's eye twitched.

She should have known better. She knew that book was magic, of course, but she hadn't thought there was enough left to matter, not in her domain. How could that little brat have tricked her into granting a wish?!

She had other playthings, more than enough to keep her entertained, but this was personal now. Nobody escaped from her daycare. Nobody.

In the playroom, Tiffany, Kendra, and Junie were playing with their dolls, on their best behavior, while Stacey let out a little grunt, finished the job of filling her post-breakfast diaper, somehow the last of them to do it this time. Hopefully, Ms. Emily would change them quickly this time, but it was always hard to tell with her.

And then, they heard something they'd never heard before. A piercing, almost inhuman scream of rage came from the office. They paused, starting to turn towards the door, wondering what could possibly have happened, when cylindrical cages slammed down from the ceiling around each of them. They had just enough time to process that, to reach out to touch the bars curiously, before the floor opened up beneath them, the cages lurching as they were slowly lowered into the floor, their eyes widening as the playroom sank out of view, replaced by darkness as steel plates slid over the holes they'd vanished into, securely locked away and out of trouble while Ms. Emily went on the hunt for the brat who had gotten away.

~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~

Matti groaned, adjusting her gym bag on her shoulder, feeling like everyone was watching her as she slunk into the gym, and like they all knew exactly why she was there.

It had been humiliating, having to call her dad the morning after everything had gone down and beg him for money, but she had no choice. She could request a new debit card online, but that wouldn't be there for a few days, and, until then, she had no way to pay to replace her room key, or car key, or her driver's license and student ID, and phone so she could get an Uber to the other school to pick up her car once the locksmith had her key ready...

She had to lie to him and tell him she'd gotten mugged, and promise not to go anywhere late at night on her own again, but luckily, he seemed to buy it. Unfortunately, there wasn't much he could do about most of it over the phone that day. "It'll be quicker for you to go to Kelsey and borrow money from her," he said. "Then I can pay her back."

"But daddy!" she whined, hating that she'd reverted to that without thinking.

"She's your sister," he told her. "She'll help you."

And she had, but only under one condition. "If I do this," she said, "I want you to try out for the cheerleading squad. And I mean, like, really try. Come to some practices to get a feel for it, put an effort in, all that. I really think you might like it, if you give it a chance. And try-outs aren't for a while, so you have time."

"Kelsey!" Matti pouted. "I don't wanna be a cheerleader!"

"And you might not be," Kelsey shrugged. "You might not make the cut. I just want you to actually give it a shot."

She could have waited for her replacement debit card to get there, or for her dad to send a check or something, but Matti had always been bad at waiting. "Fine," she gave in. "I guess even if I do get in, there'd only be one more semester until graduation."

It had seemed like an acceptable trade then, but now, as she headed to her first practice, she was questioning that. If her guy friends ever found out about this, they'd never let her live it down! And what if, somehow, she actually did wind up doing well in the try-outs and becoming, of all things, a cheerleader?! The thought was horrifying.

She paused outside the door to the room the cheerleaders were practicing in, peering in through the window to see them stretching, getting ready. Kelsey wasn't going to make her actually participate today, was she? It was her first day, so she'd probably be okay with her just watching, and Matti could hopefully look at her phone most of the time.

"Excuse me," a snotty voice said from behind her. Matti turned to see a cheerleader standing behind her, blonde and perky, a perfect example of what Matti was not. "You're in my..." the girl started to tell her, before she tilted her head, a grin crossing her face. "Wait a minute, I know you." She'd probably seen the girl with her sister at some point, but, honestly, it was hard to know for sure, since there were so many girls on the team who looked like her.

"Yeah, yeah, I'm Kelsey's sister," Matti sighed.

"You're not on the squad," the girl observed.

"No!" Matti recoiled, before reminding herself that she was going to do her best to be fair with this experience. "Kelsey wants me to try it out, though."

"If I'm not mistaken," the girl stared down at her, "you're the one who thinks you're so much better than us, aren't you? You think we're all just dumb, brainless bimbos?"

"I never said that!" Matti shook her head. She may have thought something similar, though maybe not with quite those words, and she'd tried to convey those thoughts wordlessly as she glared at her sister and her friends, during some of the many attempts Kelsey had made to get her to do this. So, maybe this girl really was someone she'd met before!

"I knew it," the girl shook her head, reaching into her own bag, taking out her phone. "I was so sure, but then I thought, no, no way could that be it." She held her phone up next to Matti's head, staring at something on the screen. "Oh, my God!" she giggled. "I knew it!"

Matti rolled her eyes. "What are you talking...?" she started to ask, until the cheerleader turned her phone so she could see it, words failing at the sight of the video playing.

It was zoomed in, fuzzy, and dark, but there was no doubt about it. There she was, running across campus in her tiny, baby dress, her diaper bobbing along behind her, clearly messy in the frame the girl stopped it on, where Matti was on the edge of a pool of light from a streetlamp. "Wh-Where did you get this?!" Matti gasped, immediately regretting going with that, rather than pretending she didn't know what it was.

"Oh, I got lucky," the cheerleader grinned. "I looked out my window at the right moment, and got a nice little show. I wasn't sure what I was going to do with it yet, but now, look at you, coming right to me. How convenient."

"L-Listen..." Matti squirmed.

"No, you listen," the girl interrupted. "Do you even remember my name?" Matti had to shake her head. "My name is Valerie," she said. "We've met, like, five times, and..."

"A-And I'm really sorry!" Matti told her. "I am! Please, you can't show that to anyone! I-I'll do whatever you want!"

"Poor, silly Matti," Valerie sneered. "Of course you're going to do whatever I want. I own you, and your little padded bottom." She reached down, giving Matti's rear a squeeze. "Oh, not in one now? Don't worry, we'll fix that soon enough. You think you're so much better than us, huh? Well, we'll just see about that, diaper girl! I'm going to turn you into the dumb, brainless bimbo slut you think we all are, so you can see how much better we all actually are than you. Because none of us run around pooping our pants like little babies. But you," she jabbed a finger into Matti's chest, "are going to be doing quite a lot of that."

Matti swallowed, looking up at Valerie, having a very hard time not thinking about her brief time with Ms. Emily, and how that had laid the groundwork for what the girl was threatening. She hated how intimidated she was by this cheerleader, how much she held her fate in her hands, but, most of all, she hated how turned on she was, squirming there in front of the taller girl, starting to fantasize about the humiliating fate that might be in store for her.

The End
