Matti's eyes were fixed on that paddle, seemingly the answer to her earlier question of whether spanking was allowed in this school. She wriggled in her seat, heart pounding, the threat of that object feeling very real, even without Jasmine saying, explicitly, what she was going to do with it. She didn't have to. They both knew what was on the line here.

Spanking was certainly a common theme in the stories, and, in them, Matti didn't dislike it. It was a fun way to show the character how hopeless their situation was, how helpless they were compared to whoever they were up against. It was not, however, one of the things that she had daydreamed about happening to her. She was pretty sure her parents had never spanked her, but they had threatened her with it a time or two, when she was really misbehaving, and that had been enough to contain her shenanigans. She'd really thought she had passed the point where she had to worry about it happening to her, long ago. Reading the descriptions in the stories, and seeing the reactions in the videos she'd watched, she was certain it was just as bad as she'd always feared.

Like most everyone Matti had been in class with for close to a decade now, when her peers were getting their final growth spurt that, for her, had done next to nothing, despite her mother's insistence that it would if she gave it time, Jasmine was bigger than Matti. Her years as a teacher had certainly agreed with her, too, her fancy clothes giving her an air of authority that Matti was positive she would have felt even if she hadn't been in a schoolgirl uniform herself, or in the diaper she had underneath. When they'd been on the trivia team, their age gap hadn't seemed like such a big deal, especially when Matti could so easily outshine her, but now, it felt huge, the difference between a true adult and a child who had been pretending to be one, until tonight, when her disguise had completely failed.

"Well, Mathilda?" Jasmine said. "I'm waiting."

Matti winced at the use of her full first name, but not daring to correct the teacher. What was she going to do?! How could she get out of this without having to experience that paddle for herself?!

"I-I don't know who you're talking about, Miss Hale," Matti shook her head. This was a stupid plan, one that was almost definitely not going to work, but in the moment, it felt like the best one to her. "Th-That's not my name. You've mistaken me for someone else, ma'am."

"Oh, I did, did I?" Jasmine raised an eyebrow. "Then who are you?"

Matti's mind went blank, and she spouted out the first name that came to mind. "I-I'm Sierra, ma'am. I-I just started here, and I don't have any classes with you yet, but some of my friends told me about you, a-and that's how I knew your name. I-I'm very sorry, Miss Hale, you're right, I shouldn't have been out of my room after curfew, and I swear, I'll go right back there right now if you let me..."

"Why were you out of bed?" Jasmine demanded. "What were you up to, 'Sierra?'"

Matti squirmed, the woman's tone letting her know that she wasn't buying this, that spanking feeling like a more and more real possibility. Embarrassingly, she could feel herself getting wet again, despite her fear. She'd fantasized about being trapped in diapers, and, in a lot of cases, this was a part of that. That had just been a fantasy, though! It didn't mean she wanted it to happen for real!

Jasmine had started typing at her computer, however. Maybe Matti was overthinking it, letting her imagination get the better of her. Maybe she was checking to see if there were any Sierras registered here. Matti didn't want to get them in trouble if they were, but hopefully if Jasmine saw that name pop up, she'd have some second thoughts about this.

"I-It was Aubrey!" Matti exclaimed, fine with throwing that girl, and her cronies, under the bus after what they'd done to her. It was a good plan, she thought, even if there was no reason those girls would back up her story. Maybe Jasmine would go fetch them and bring them here. On one hand, that would be awful, since, after they said she was lying, she doubted Jasmine would make them go back to their rooms without giving them a show, letting them witness her punishment. On the other, she might leave Matti here while she did that, and Matti would have the chance to escape. Even if she took Matti with her, there was a possibility that Matti could pull free from her grip on the way to the dorms, although running away still seemed unlikely given how much taller Jasmine was than her.

"Sh-She invited me to go smoke with her friends," Matti continued. "I-I've never smoked before, but I thought it would be good for me if I could make some older friends, so I was going to give it a try, but they just wanted to bully me."

"Aww, poor thing," Jasmine mocked, Matti blushing at the complete lack of sympathy she was getting. Jasmine wasn't even bothering to stop clacking away at her keyboard to listen to her! Maybe she deserved it, to be honest. She had gotten bullied, but since she was older than those girls, it was hard to expect anyone to feel too sorry for her over it. "You know what? Maybe I was wrong. Maybe you are just a freshman. There's no way anyone older than that would make up such a stupid lie and think it was going to work."

Matti blushed, hanging her head. She'd known it was a dumb plan, but hearing someone else say it still stung. After she'd stopped playing soccer, her grades had felt even more important to her, and, while they'd been good before then, she'd worked hard to make sure they were excellent afterwards. Even if Jasmine wasn't really her teacher, it was very obvious that was what she was, and having a teacher call something she did stupid shook her in a way she hadn't expected.

"And since you are a freshman," Jasmine said, "you're up well past your curfew, and that means you need to be punished."

Matti's eyes darted back to the paddle, Jasmine smirking as she noticed. "That's right," she taunted. "A nice, long spanking ought to teach you to stay tucked snugly in your bed, instead of roaming the halls."

Matti bit her bottom lip, realizing she may have made things worse for herself. Jasmine didn't really think she was Sierra, did she? It hadn't sounded like it, but now she was going all in on the story. At least when she'd been calling her Mathilda, the threat had only been implied!

"N-No, you were right!" Matti exclaimed. "I-I don't go to school here! It's me, Matti!"

"Oh, I don't know about that," Jasmine shrugged. "I think you're just trying to get out of trouble now, and it isn't going to work."

"N-No, I am!" Matti insisted.

"Then prove it," Jasmine demanded. "Prove to me why I shouldn't bend you over my desk right now and warm your backside."

Even in the midst of her panic, Matti couldn't help squirming, a heat rising in her at the thought of her former rival doing that, pushing her over her desk, lifting her skirt, finding her diaper. Would that make her more or less likely to follow through on the spanking?

"Right now, Sierra!" Jasmine snapped. "I'm starting to lose my patience with you! One... Two..."

Matti didn't have time to think it through. "Okay!" she squealed, leaning over, opening up her messenger bag, the real, shrunken Sierra scrambling out of the light as Matti fumbled with the shorts she'd stuffed into her bag, knowing her wallet was in there, with her driver's license and student ID in it. She really wished now she'd taken more care with how she'd put her old clothes in there, as they were a huge jumble, and every passing second, as she attempted to untangle them, she was certain her punishment was drawing nearer.

"Here." Matti jumped as she saw Jasmine's hand push past hers, into the bag, having been so preoccupied that she hadn't noticed the woman standing up from her desk and walk over to her. "I'll do it."

"B-But..." Matti protested, seeing Jasmine yank the whole mass of cloth out of her bag, her whole outfit, other than the underwear she'd had taken from her at the nurse's office, her wallet, even her keys, in the other pocket of her shorts.  Without that, she had almost nothing!

And then, as if sensing that 'almost', Jasmine paused, peering into the bag. Matti gulped, sure that Sierra had been spotted, hoping she'd stay perfectly still, and that, if anything, Jasmine would mistake her as a doll, and assume that anyone carrying around a doll was obviously not a college senior after all. Or was that what she wanted Jasmine to think? Matti couldn't even remember for sure now!

"I'll take this, too," Jasmine reached in, Matti holding her breath. For a moment, she was relieved not to see Sierra being plucked out of her hiding spot, until she saw that it was, instead, her phone.

Now Jasmine really did have everything, every connection Matti had to her real identity, everything she could use to easily get herself out of this mess. Despite, or probably because of, the hopelessness of her situation, how much her fate rested in the hands of Jasmine, Matti could feel her diaper growing wetter beneath her. How much was she going to have to beg to get it all back? What was Jasmine going to make her do?! There were so many absolutely mortifying possibilities, all of which were only amplified in their humiliation factor by the diaper hiding under Matti's skirt, and the possibility of Jasmine discovering it, having that one more thing to hold over her head.

"Well, well, well," Jasmine smirked, pulling Matti's wallet out of her pants, looking at her IDs. "Isn't that funny. These say your name is Mathilda after all, Sierra. But they also say you're a college student, and there's no way that's true, is there? So these must be fake." She slid the driver's license and student ID out of the wallet, holding them up. "Isn't that right?"

Matti gulped, her head swimming. "I-I don't know," she said, so turned around that she wasn't sure what else to say, what the best option was.

"You don't, huh?" Jasmine stood up again, stepping around to the other side of her desk, looming over her. "Let me make this simple for you, then, since you clearly need that. You're either a naughty little freshman who was up past her curfew, or some weird adult that I caught wandering around my school for God know what reason. I'd have to assume you're some sort of pervert and call the police to come pick you up."

Matti couldn't believe how sticky her diaper was, how wet, how turned on she was. If she'd have been in her undies, they would have been drenched, but, then again, if she was in her underwear, she never would have been this horny. Or so she assumed, since it had never happened before to this extent, which only made it more humiliating, and turned her on more. What was wrong with her that this was the only thing that did it for her to this extent?! If the police did find her this way, it would be hard for her to claim she wasn't some weird perv.

Maybe the reason she couldn't decide on the best option was that there wasn't one. There was no easy way of getting out of this, and while, in a story, that made it all the more delicious, and after a full day of immersing herself in these sorts of stories it was hard not to find some perverse enjoyment in that, in reality it was kind of scary.

"Th-They're fake," she said at last, hoping she wouldn't regret it. After seeing those, and confirming that it was Matti, if that had ever really been in question, Jasmine wouldn't really think she belonged here, would she? Matti was still at her mercy, which was probably a very bad position to be in, but, in the long run, it was better than a run-in with the police, and the possibility of this going on her record, right?

"That's what I thought," Jasmine declared, reaching behind her on the desk.

By the time Matti saw what she was reaching for, it was almost too late. She was able to get out a futile, "No!" as she leaned forward in her desk, eyes wide, but that did nothing to stop Jasmine from putting the cards between the blades of the scissors she'd grabbed, slicing them each in two, then taking those pieces and slicing them in half again.

"You won't have any use for those," Jasmine told her, marching back to the other side of her desk, opening up a drawer and dumping the remains of Matti's IDs into it, sweeping her clothes and phone in as well before closing it. "I'm sure the office will be annoyed that you lost your ID here so early in the school year, but you can go get a new one tomorrow."

"B-But I don't need an ID here," Matti stammered. "C-Come on, Jasmine, you know..."

"Miss Hale!" Jasmine snapped, Matti squeaking, melting a bit at that display of authority. "And what I know is what you just told me, Mathilda. Those were fake IDs, which means you need to get a real one to show everyone that this is where you belong."

She still had no idea if Jasmine was aware of the diaper hiding beneath her uniform, but it was hard not to think of that statement as including that. Matti, the college senior, belonged here, at high school, as an accident-prone freshman, one who was no doubt going to be in for quite a lot of teasing from Aubrey and her gang when they found her again.

"Although, I have to say," Jasmine grinned, reaching for a shelf at the bottom of her desk, picking up a piece of paper from the printer there, strutting back to Matti's desk, "from the look of things, you might not be staying for long. It's so sad that you're struggling so much, so early in your time here."

She slid the paper across the surface of the desk, Matti gasping at what she saw. There was her name across the top, and, underneath, a list of classes and grades, all of which were letters she'd never seen on a report card of her own before. She was on the verge of failing each and every one of them, a single less than perfect grade probably enough to send her over the edge in each. They were all things she was familiar with, of course, but she had no experience with this school's specific curriculum, and it had been a while since she'd taken some of them. It would be easy to miss a couple questions, especially if there was a pop quiz before she had the chance to do any studying, and then...

"A straight D student," Jasmine shook her head. "How sad. And, since you're a freshman, you may not know, but an F means a trip to the headmistress's office. And you'd better believe she has a paddle of her own."

This was so humiliating! Being taken from being a college senior, getting all A's, to a high school freshman teetering on the edge of flunking out, and being kept in diapers as the cherry on top! Matti bit her bottom lip, her toes curling in her sneakers, fighting to keep from reaching between her legs, almost overwhelmed by it all, only the reminder that this wasn't a story, that it was happening to her, stopping her.

"I think you'll find that you do, in fact, have a class with me," Jasmine pointed out. "Which means that no matter how well you do in your other classes, you'd better be the perfect little teacher's pet for me, or you will be taking that trip to the headmistress's office. I am going to have so much fun with you!" She pinched Matti's cheeks with a sinister laugh. "For now, though, I get to have my turn with the paddle, and then we'll go pick up the key to your new room from the office. I can't believe you lost that already, too! You'd better be glad the secretary isn't here on the weekend, or she'd probably give you a few swats of her own for that."

Somehow, in her worries about her future, and any spankings that might be coming to her then, Matti had forgotten about the one looming over her now. She stared up at Jasmine, wide-eyed. "Pl-Please, Miss Hale," she gulped. "I-I'll be good!"

"I know you will," Jasmine nodded, stepping to her desk, picking up her paddle. "They all are, after I'm done with them. Now get up here and bend over."

Matti squirmed in her seat, in her bulky, sticky diaper. This was it. If Jasmine hadn't known about her diaper now, she was about to. And if she gave it a squeeze, discovered the state of it... Jasmine might think she really was just here being a perv, and that call to the police might happen after all. Would that be better or worse than what Jasmine had revealed her fate here would be? She didn't know, but she couldn't bare the thought of Jasmine finding her like this. She had to hide it, and there was only one way she could think to do that.

She had been curious about this anyway, had been tempted to do it as soon as she'd been put into the diaper, but had been having a hard enough time getting used to the diaper normally. She wiggled, trying to start, her body refusing to comply.

"Mathilda," Jasmine told her, "Get up here."

Matti shook her head, pushing desperately, her potty training betraying her. Or, rather, doing its job perfectly, the one time she didn't want it to.

"You think you can tell me no, young lady?" Jasmine fumed. "Now!" she pointed at her desk.

Matti closed her eyes, attempting to pretend she was alone, in the bathroom, sitting on a toilet. The fact she was sitting did help a lot, although the teacher berating her in the background definitely didn't. "One..." she began to count again, Matti hating how well that childish manipulation worked on her, making her frantic. "Every number I count is another five swats," she warned.

Finally, Matti felt a trickle, a bloom of warmth soaking into the waiting padding, but even her excitement at that wasn't enough to keep her body from rebelling, feeling the sensation of an accident and assuming that, as usual, it was a bad thing. "Two..." she heard Jasmine continue.

"Come on," she whispered, trying again, not knowing how long Jasmine would let her go before she yanked her up off the chair, which was going to make this even more difficult.

"Three... You must really not want to sit down for a while."

At last, there was another trickle, and this time, Matti pushed through her bladder's instincts, pushing harder, turning it into a stream. She swallowed a sigh of relief, not wanting to tip Jasmine off about what was happening, as the padding beneath her turned warm and squishy. Just like the diaper itself, it wasn't quite what she'd expected. If anything, it made her appreciate the dry diaper more, the trapped heat of that nothing compared to what she could feel now, hugged tight against her shaved crotch by the snug padding.

"Four..." Jasmine sighed. "You really don't think I'm going to do it, do you? It's your funeral."

Matti stumbled to her feet, feeling the now truly soaked diaper squish between her legs, making her blush. "O-Okay!" she said. "I-I'll do it!" Gulping, she positioned herself, bending over the desk, nibbling her bottom lip as she looked back, glad to see that it seemed the skirt was long enough to cover her diaper, if just barely. That would be good to know in general, though for now, she doubted it would matter.

"You'd better get comfortable," Jasmine warned. "You're going to be here for a while."

Matti's breath quickened, knowing the moment was approaching as the teacher positioned herself, taking a moment to adjust the paddle to just the right angle, taking her time, building up Matti's anticipation, and fear, and excitement. Any moment now, Matti thought, she was going to bend over and lift that skirt, and find her diaper.

She was so busy waiting for that, she wasn't ready for the spank itself, hadn't braced herself in the slightest. "Ouch!" she yelped, pain shooting through her body. The stories always talked about the diaper providing some protection, but if that was the case, she was truly scared by what that would have felt like on her bare bottom. Already, just from that one swing, it stung, and she could practically feel the welt growing beneath her padding, turning pink and swollen and tender. "Th-That hurt!"

"Of course it did," Jasmine smirked. "That's the point." And, as if to prove it, she gave Matti another, the girl squealing and trying to wriggle away, tears already springing to her eyes.

Had she wet herself for no reason? She had other concerns at the moment, of course, but she couldn't help wondering that as she whimpered, bouncing in place. She'd been so sure Jasmine would lift her skirt, because that was how it happened in the stories, but she hadn't done that at all, or even mentioned it! She blushed, feeling as stupid as that report card showed her to be at making that assumption, being so sure of herself that she'd been willing to pee her pants, and taking so long to do that she'd earned herself twenty extra spanks!

Twenty. The number made her shudder. She had no idea how many the initial spanking would have been, but she'd only gotten two so far, and even just twenty on their own felt impossible to take. She was so grateful for that diaper, and however much it was shielding her.

It was another three swats before Jasmine paused. "What in the world are you wearing, Mathilda?" she asked, poking at Matti's already throbbing bottom with the paddle. "I thought it was my imagination at first, but I've definitely never heard that sound before."

Matti's stomach sank, her anger at herself for peeing her pants for no reason turning to embarrassment as, finally, Jasmine's hand inched towards the hem of her skirt. She opened her mouth to tell her to stop, but, since she had no follow up if Jasmine asked why, perhaps it was for the best that she she was able to produce only a wordless squeak of pain as the skirt was raised.

"Oh, my God," Jasmine snickered. "Are you serious right now, Mathilda?" Matti groaned. "Why are you wearing a diaper?" Jasmine demanded. "You don't need them, do you?" Matti shook her head as Jasmine gave the crotch of her diaper a squeeze, at least justifying what she'd done, though it was hard to feel too grateful for her past self in this moment. "Then why are you soaked? Oh, my God! You really do belong here! I always knew you were a big baby, but I never thought it was this bad!"

Matti gasped at the feeling of fresh, cool air on her bottom. It did feel nice, but she knew what it meant, as her diaper was slid down, exposing her to the paddle's full wrath. "I can see why Aubrey and her friends were teasing you," Jasmine said. "If only they knew the truth about you. Maybe I'll have to let them know who you really are, and that they're free to torment you as much as they want, as far as I'm concerned. Aww, look at how red your face is getting! You know you deserve it!"

"N-Nuh-uh," Matti replied weakly.

"Oh, you don't?" Jasmine smirked. "Let me see."

To Matti's surprise, and relief, she set the paddle down, walking away for a moment, returning with the report card, setting it down next to Matti's face, the watery eyes behind her glasses having a hard time seeing it clearly. Jasmine took a pen, scrawled something on it, then held it up, giving Matti a better view.

There, at the bottom, Jasmine had added in one more 'class.' It was, of course, Potty Training, and for the grade, she'd put a big, fat F. "Don't worry, though," she patted Matti on her head as she stepped away again for a moment. "I won't tell the headmistress about this F. We'll just handle it ourselves, how about that?"

"Ow!" she shrieked as the paddle smacked down on her again, this time on her bare skin, just as bad as she'd thought it would be.

"Much better," Jasmine nodded sadistically. "Now we can really get started. I hope you're ready."
