"What was that, Miss Nivera?"

Sierra winced, squirming in her seat, feeling the slick plastic of her diaper sliding over the finely polished wood of her desk's chair. It was so hard to sit still! At first, she'd assumed that was a mistake, or an oversight that had been made when this school had been built, like whoever had chosen the seats hadn't realized most, if not all, of the students there were going to be diapered, but, before long, she realized it was almost definitely intentional. If a little girl couldn't keep herself from squirming, since she had to do that to stop from sliding right out of the chair, there was always something to punish her for.

That wasn't why she was in trouble this time, however. "Come on, then," the teacher said, stepping closer to Sierra's desk, right in the front of the room. If she had a choice, Sierra preferred to sit further back, so she could hide and hope the teacher forgot about her so they wouldn't call on her, but, almost as if the teachers here knew that, they all assigned her to sit in the first row, where they could 'keep an eye on her.' "If you have something to say, stand up and share with the whole class."

Sierra knew better than to do that. She should have known better than to say anything at all, but the 'assignment' for the class was so stupid, she hadn't been able to stop herself from muttering under her breath. Of course the teacher had been watching her like a hawk, and caught her.

"Stand!" the teacher ordered, tapping the top of Sierra's desk with her paddle, making Sierra jump, feeling her diaper grow a little damper as she scrambled to her feet. Here, that would be seen as a good thing, though. She gulped, staring at the paddle, and the 'Q' carved into it. All the teachers had one waiting nearby here, just in case they needed it, which seemed to happen very often. Of course, in a place called a 'School of Hard Swats', that wasn't exactly a surprise.

"I-I was just saying," Sierra said, frantically searching her mind for a suitable fib, "that I f-felt sorry for you to have to change everyone after this lesson."

She knew right away she'd made the wrong choice. If she'd been called out for talking, the teacher had probably at least seen her mouth moving, if she hadn't actually heard what Sierra had said. She surely knew that Sierra hadn't said anywhere near that much.

She never found out if that was the case or not, however, because the girl in the desk next to Sierra raised her hand. "That's not true!" she tattled, as soon as the teacher nodded at her. "She said this was stupid, and she isn't a baby!"

Sierra glared at the girl, wishing very much she could do something to her for telling on her. She should have been able to, after all. She was a witch! At Hogwarts, she'd been doing so well, even if that was at least partially because she was in a class for kids far younger than her. Unfortunately, the stuffed badger sitting on her lap had drained all her magic, and she had no idea how to get it back. And, to make matter worse, she couldn't bear to be away from it, which was all it needed to keep siphoning away her powers, to ensure she couldn't recover.

It had been a particularly dastardly plan from those awful Slytherins. Turning her wand into a paddle had been pretty mean, too, although, if there were any positives about her situation, it was that at least it, and the snake enema bag, had been kept away from her while she was waiting to be auctioned off. They'd tried to separate her from the badger, which might have actually allowed her to escape, eventually, but she'd involuntarily launched into such a huge temper tantrum that she'd been 'allowed' to keep it.

Sierra fidgeted in place, listening to the chain between her ankles clink softly, reminding her of how serious this really was. There weren't many students who had them, just a few, like her, who were waiting for the auction, and some who had been sold off previously whose owners had decided to enroll them here, and keep them restrained, 'just in case'. It still didn't feel completely real, despite having been there for several days. She had no idea who was running this thing, or how the Slytherins had found out about it, only that, if she couldn't find a way out of here, she was going to be sold off as a Baby Slave. Nobody had told her when it was going to be, or what that position entailed, although the name itself gave her a pretty good idea, only that her time here at the school was designed to make her more desirable.

Saying that she wasn't a baby, therefore, only proved her lessons hadn't been sinking in. She opened her mouth to deny it, but she knew better. All her resistance had done so far was land her at the bottom of all her classes, and earn her more than her share of spankings. The teacher would believe anyone else in the class over her, if she hadn't heard what she'd said in the first place. Lying would just make things worse. It was definitely better to say nothing.

"Is that true, Miss Nivera?" the teacher asked, stepping even closer to Sierra, making the girl very aware of how short she was compared to the woman, how helpless she was here, as she clutched her badger to her chest, another trickle of warmth soaking into her diaper as she swallowed anxiously.

"Honestly," the teacher sighed, taking Sierra by surprise as she poked at her diaper with the tip of the paddle. Sierra's skirt didn't come close to covering her diaper, just like everyone else's uniform, and obviously the teacher was very used to seeing people wet themselves. She should have known her accidents wouldn't be a secret for long. "It seems like you should be a natural here, yet, for some reason, you refuse to learn anything."

"I am not a natural!" Sierra grumbled, despite herself. "I don't belong here!" She'd been doing so well at Hogwarts, and not just in her classes. She very rarely had daytime accidents, and even at night, she'd mostly stopped. Just a little while here, however, and all the control she'd worked so hard to re-establish was slipping away, even more than she'd realized, she thought as the paddle made more of a squish against her diaper than she had expected.

"Whether you do or not," the teacher said, making it obvious which side she was on, "you're here. You've mastered the art of using your diapers, but that isn't all there is to being a proper Baby Slave."

"Well, I don't want to be that!" Sierra protested. "I'm an adult!"

"Maybe at one time, you were," the teacher shrugged. "Now, you're a Baby Slave, and it's my job to make you see that. Now, are you going to do your assignment or not?"

"No!" Sierra refused. The 'assignment' was for each of them, individually, on command, to fill their diaper, then find some way to convince the teacher they loved doing that. There was no way she was going to subject herself to that, so she might as well make sure the teacher knew that now, and got it over with. She'd probably have called on Sierra first, anyway.

"That is very disappointing," the teacher sighed. "I've been putting this off, but clearly, it was a mistake. Go to the corner, young lady."

"Fine!" Sierra scowled, wishing her ankles weren't chained together so she could stomp her foot. It wasn't like this was the first time she'd been sent to the time-out chair. Honestly, it was probably better to spend classtime there, than having to listen to teachers trying to indoctrinate her into being a mindless, obedient, diaper-loving slave. Usually, though, she got a spanking first, so it wasn't exactly a pleasant experience. Her bottom was still a bit sore from the last one she'd gotten, but enough time had passed that, along with the padding of her diaper, the hard surface of the naughty stool wasn't too awful.

The stool did have the same problem as the desks, combined with her diaper, and, unlike the desks, there was no back on the stool, so it was even more difficult to sit still. It was also even more imperative she did so, however, since her bottom coming off the stool for even a second, even if it was because she was falling and couldn't help herself, would count as trying to escape, and earn her detention.

Normally, she'd be left over there to squirm and think about what she'd done, but, to her surprise, the teacher appeared behind her after a couple seconds. "What?" Sierra whined. "I haven't gotten up!"

She regretted her attitude immediately, realizing it was possible the teacher had realized she'd forgotten the customary spanking, and was there to deliver it. Fortunately, that didn't seem to be the case, since the teacher said, "And you'd better not," rather than yanking her off the stool.

Instead, she placed something on top of Sierra's head. It wasn't heavy at all, and slid down over her hair easily, like a hat, but there was definitely something about it that felt strange. Sierra reached up, feeling what seemed to be a cone of paper, stretching up and up, tall enough she couldn't quite reach the tip.

"Leave that alone!" the teacher scolded.

Sierra blushed, nibbling on her bottom lip. She couldn't see it, of course, but she had a bad feeling that cone had the word 'Dunce' written on it, that she was being shamed for not being 'smart' enough to accept her fate. This was so dumb! She pouted, wiggling in her seat, imagining what she would do to the teacher if she just had her wand.

There were tons of great spells she could use. Technically, since she was outside of Hogwarts, she wasn't supposed to use them, but this was a special case. Besides, unlike most students, she was old enough that they couldn't really stop her, only encourage her to be careful. If they knew what was happening, though, they'd probably be okay with it. Maybe they'd even join in, and hit this mean woman with a...

Sierra frowned. She could think of the spell she was considering, yet, when it came to its name, her mind was drawing a complete blank. That was weird. It wasn't even anything difficult, she was pretty sure. She'd learned it a long time ago, at Ilvermorny, but now, it was so fuzzy. She tried to remember how to cast it, thinking that might help. Instead, it made her more worried. There were definitely words she had to say, and a wand movement, yet she had no clue what those were. She was positive she'd cast it so many times at... at...

"Oh, no," she squeaked.

"Do I hear talking from the corner?" the teacher snapped.

Another spurt of pee-pee cascaded into Sierra's pants as a wave of fear overcame her. What was she supposed to do?! She'd been in this exact situation before, but now, she couldn't remember if the teacher wanted her to answer, or if doing that would be counted as more talking, and get her into trouble. She'd learned it so early on, and it had stuck with her, as an essential survival fact, but now it was buried as deep as the names of her previous schools.

She sniffled, her thumb moving up to her mouth, as her other hand clutched her stuffed badger a little tighter. She could feel wetness on her chin as her thumb brushed past it, realized she was drooling. She suspected she might be dribbling elsewhere, too, but her diaper was already so wet, and she didn't dare do much squirming to test the squishiness, because she knew if she fell off the stool, that was very naughty.

"Oh, my," the teacher chuckled, plucking the hat off Sierra's head. Sierra could see there was something on it, and that they might have been letters, but she couldn't read them any more than she could remember what she'd thought it said. "That was much quicker than I expected. I guess there wasn't much in there to scramble, was there?"

Sierra stared up at her, sucking her thumb, drool dripping from the corners of her mouth. She should probably be insulted by that, but she could barely piece together what the woman had meant. There were so many big words, way too many for her to try to decipher. Cautiously, she nodded her head, hoping that was what the grown-up wanted from her.

"Now, then," the teacher smiled, helping Sierra off the stool, keeping ahold of her hand so the girl didn't fall flat on her face once her feet touched the floor. "Are you ready to do your assignment, Miss Nivera?"

Sierra nursed her thumb a little harder, eyes, and mind behind them, blank. What was she being asked? She tried to think about that word the grown-up had used, and giggled to herself, thinking about how funny it sounded. Ass! That was a bad word, but also a word for her bottom! She gave it a little shake, giggling again at the sound of her diaper crinkling.

There was something else her bottom could do, besides wiggle. She felt a pressure in her tummy, and, without thinking, gave a push, listening as her diaper started to crinkle in a different way, slower, as it expanded, mixed with her own grunts, and other noises. It all seemed so right, so natural, it took a while for her to notice the mushy mess building up inside her diaper. Even then, she wasn't certain what it was, poking at it and whining, not realizing she was the one making it happen.

"What's wrong?" the teacher asked. "Don't you like it, Sierra?"

Sierra stared up at her, furrowing her brows. Was she supposed to like it? She knew so little, she wasn't sure. She supposed it wasn't so bad, really. She wriggled some more, feeling the goo move and shift, feeling her cheeks warming despite herself, even as she told the woman, "Yeah!"

"Then why don't you sit here on the floor and enjoy it?" she suggested, helping Sierra down, so she didn't fall, letting her sink into her dirty diaper, the sensation of the mess squishing between her legs making her deeply embarrassed, yet proud of doing what she'd been told, at the same time.

Slowly, throughout the rest of the class, Sierra felt her mind piecing itself back together, making her more and more humiliated at what had happened. She had no idea if that dunce cap was magic, or some kind of Muggle technology, but whatever it was, it was terrifying how powerful it had been, and how helpless she'd been against it. Maybe, if it wasn't for the badger, she could have fought back a little, but she wasn't sure if it would have done any good or not, really.

Sierra stayed there on the floor, even after the effects had worn off, not wanting to draw attention to herself. Once the teacher dismissed the class, she tried to clamber to her feet, having some trouble with the chain between her ankles, only for the woman to order her to, "Stay put," anyway.

After the rest of the students left, the teacher knelt down in front of her. "You see, Miss Nivera," she smiled evilly, "we can make you into the perfect little Baby Slave, whether you like it or not. It's up to you whether you go along with your lessons like a good girl, or if you resist, and we have to do it by force. Or, I guess, once the auction happens, that will be up to your new owner."

"I-I don't want an owner," Sierra sniffled.

"Well, that's too bad," the teacher told her. "A cutie like you will definitely sell, so you'd better either hope that whoever buys you wants a brat, or start trying harder. Do you understand?"

Sierra gulped and nodded, snuggling her badger tightly. She really did now, far more than she had before. She might not want to mindless, diaper-loving little girl, ready to do anything she was told by a grown-up, but this school could turn her into one anyway, at one word from her owner. She really hoped those Slytherins were planning on getting her out of this before the auction, although, the longer she spent here, the more worried she was that she'd seen the last of them, and, instead, she should be following this teacher's advice.

"Now, go on," the teacher helped her up, sending her out of the classroom with a hard swat on her full diaper. "You don't want to be late for your next class, do you? Guess you'll just have to skip the changing room for now."

"Y-Yes, ma'am," Sierra nodded, blushing as she shuffled along as quickly as she could, not even noticing that she'd started sucking her thumb again as she hurried down the hallway.
