Sierra smiled in triumph as she bent down, grabbing the other girl's wand. The taller Slytherin scowled at her as the huge stuffed rabbit forced another bottle into her mouth, but she couldn't do much other than that. Sierra had to admit, she'd felt a little nervous about this duel, but it had gone even better than she could have hoped! And now, with only a few weeks before her graduation, she had another win under her belt!

She slid both her wand and her opponent's into her robe pocket, then gave the defeated girl's diaper a pat. Maybe she should have gone a little easier on her. There was a chance this was the girl's first real wizard duel, since she hadn't been able to find any rumors about the girl's style, not that it had mattered. Since she had barely even managed to touch Sierra in the battle, Sierra supposed she should be nice, only teasing her a little bit before giving her wand back and letting her be on her way.

"Now, then," she said playfully. "What should I do with you? You're just so cute like that! Maybe I should shrink you down and keep you in that dollhouse over there! Wouldn't that be fun?" She giggled a little, remember how Olivia had threatened her with that, back in their second duel. It hadn't seemed funny then, at least not until Sierra had used that dollhouse to her advantage. "I can come back and play with you whenever I want! That's what you said you heard, isn't it? That I'm just a silly overgrown little girl who likes dressing up her dollies and can barely keep her pants dry, much less use magic? Well, I think I did all right with my magic this time, don't you? And you're the one in wet pants! But I do feel like having some fun with my new doll."

"That's enough, Ms. Nivera!" Sierra gasped at the all too familiar voice coming from behind her, freezing even before the invisible ropes bound her arms to her side. Her cheeks blazed bright red as she felt a warmth began to run down her thighs as she helplessly listened to the sound of the Headmistress's footsteps approaching.

"I-I'm sorry!" she squeaked, struggling in vain. "I didn't go looking for her! She came to me wanting a duel! It isn't my fault!"

"You promised me last time that you were done with this nonsense," the Headmistress shook her head. "And I thought after spending a week with the first years you really had learned your lesson. I told you I can't have this kind of thing going on at my school."

Sierra's blood ran cold as she remembered the conversation. The Headmistress had told her she would hold Sierra back a year, then send her to Hogwarts's reform school the next year. Sierra had been certain that didn't actually exist, but when she'd asked about it, she'd heard an awful lot of rumblings from people who at least believed that it did. "B-But I only have a few weeks left!" she whined, biting her bottom lip. "I'm almost done with my N.E.W.T.s!" Those were the final tests she needed to take to be able to graduate! She was so close!

"I know, Ms. Nivera," the Headmistress told her gently. "But I can't just let this behaviour go unpunished. What am I going to do with you?"

---------------------------------------------------------------

That was the question still going through Sierra's mind the next morning as she sat in front of the nurse's office at a strange, new school. She had been woken up early and bundled off to the train with all of her school supplies, but none of her clothes or personal belongings other than the uniform she was wearing. Well, that and Miss Hoppikins, who Sierra had hidden in her bag.

It had been a long ride, alone in her train compartment, feeling just as nervous as she had the first time she'd gone to Hogwarts, with just as little an idea of what to expect. All she'd been told when the Headmistress had seen her off was, "The punishment will fit the crime."

That didn't help with the nerves she had been developing since she'd been caught. Neither had the conversation she'd had the night before with some of her friends, as she'd tried to find out if there really was some secret reform school Hogwarts used for its naughtiest students. They'd heard plenty of rumors, but of course didn't know anything for sure. They did seem convinced that since she was an adult now, the school would be even tougher on her.

She wasn't sure if it was fortunate or not that this train ride was far shorter than that first one. She had less time to worry about what was in store for her, but that also meant that she couldn't put her fate off for too long. And this time, she knew that whatever was waiting for her was not pleasant.

Outside the window, she could see something coming into view at the end of the tracks. It was dark, stretching up higher and higher as they seemed to inch their way towards it and she eventually realized it was a very tall fence. The train chugged forward straight at it with no sign of slowing, its path seeming to lead it right into the side. Sierra wondered if this was like Platform 9 3/4, where the wall was merely an illusion, although she still felt a bit nervous as they got closer and nothing happened. Right before the train collided, a section of the wall swung open, just big enough for the train to enter, sliding shut behind them.

Only once the train was inside did it start slowing down, though the ride still went on for a little while longer, going several miles at least, to what looked to Sierra like the very center of the huge fence, and the castle sitting there. Sierra was confused at first, because what she was looking at was almost exactly the same as what she had left, to the point where she almost wondered if the whole trip was meant only to scare her. The location was clearly different, however, since there was no Great Lake between the train and it. And as the train pulled to a stop outside of it, Sierra realized that, although it looked almost identical in most other ways, this castle was much smaller than Hogwarts.

She had a couple minutes to ponder that before the curtains on her train car closed suddenly, blocking out her vision outside. She bit her bottom lip as she looked around, wondering if this was a sign that she was supposed to get up and go outside now. She hadn't been told much of anything. She knew she would have to go into that new school at some point, but there weren't any announcements telling her it was time. If she waited long enough, would the train go back to Hogwarts? She knew she would probably get in trouble if she was still on it then, but if they didn't tell her what to do, how was she supposed to know?

Sierra jumped at the sound of a tap at the compartment's door, turning to see a shadow lurking outside. She expected whoever was out there to burst in, but instead there was another knock. "Come in?" she said uncertainly, unsure of what to expect.

The woman who opened the door was not at all what Sierra was expecting. She was short, hardly taller than Sierra, and quite pleasant looking. She smiled at Sierra, offering a hand. "Oh, good, you're awake! I know it can be a boring ride, and they got you up rather early! You must be Ms. Nivera! I'm Madame Wright!"

"H-Hi," Sierra shook the woman's hand, still a little nervous. "Do you run this school?"

"Me? Oh, no!" Madame Wright chuckled. "I'm just the head nurse! I'm in charge of getting you your new uniform, and all settled in."

"New uniform?" Sierra's ears perked up at that. She didn't want to be stuck in this place, but after being stuck in the same uniform for most of seven years, the idea of getting something new to wear was probably more exciting than it should have been.

"Oh, yes," Madame Wright smiled. "We have our own uniform here. Although yours will have its own special addition."

Sierra's cheeks burned red at those words. She had a bad feeling she knew exactly what that meant, especially after what the Headmistress had told her about her punishment.

"Now, we'd better make sure you didn't try to bring in anything naughty. I'm sure you didn't, but I have to check! I'm sure you understand!" Before Sierra could say anything one way or the other, the woman began to rummage through her things, spreading them out around the train compartment. Sierra barely had time to open her mouth before Madame Wright had pulled Miss Hoppikins from her bag, holding her out with a shocked look. "What is this? A little hitchhiker?"

Sierra began to blush again, and she only grew redder when she realized the woman actually wanted an answer. "Yes?" she tried.

Madame Wright shook her head. "I think that's a lie, don't you? Very disappointing, Ms. Nivera. I'm sure you were scared, coming to a new place, but you were told to leave everything that wasn't necessary for your studies at Hogwarts, weren't you? I'd love to let you keep your little friend here, but that would be unfair to your classmates. I'll tell you what, though, I'll keep her with me, and any time you want to see her, you can just visit me, all right? And when you graduate, you can have her back. How about that?"

Sierra hated to admit it, but she couldn't remember ever having slept without Miss Hoppikins. Even though her stuffed bunny had been used against her in some of her duels in some very embarrassing ways, the thought of going to bed without her still made her feel a little more anxious about this whole situation. She didn't realize how much until Madame Wright reached up, wiping away a tear she hadn't noticed herself crying.

"I'm sorry, dear. Rules are rules. I promise, I'll take good care of her." Madame Wright enveloped Sierra in a big hug for a few long minutes before saying, "And I'll take good care of you, too. I'm glad that was all you tried to sneak in. Now come on, let's get you settled in."

With a wave of Madame Wright's wand, Sierra's things had gathered themselves back up, tucking themselves into her bag or stacking themselves into a neat pile. They levitated behind the pair as Madame Wright led Sierra off of the train and into the castle. The only item kept separate was Miss Hoppikins, who was hopping along with them, much to Sierra's humiliation as the castle's doors opened and she saw her new classmates milling about inside.

She wasn't sure what she was expecting, but despite being the 'bad kids', the students didn't look that different from the ones she'd just left at Hogwarts. They were, indeed, in a different uniform, but that didn't make that much of a difference. Instead of the robes and ties Sierra was used to, these kids were wearing what looked more like a Japanese school uniform, at least from what Sierra had seen of them in cartoons. They were sailor uniforms, with shorts for the boys and skirts for the girls. The main color of the uniforms were color coded after the primary color of each student's House and the trim and bow tied around the neck of the top were the House's other color. It definitely was different, but Sierra wasn't sure it was much of an improvement, if any.

One thing that worried Sierra about the students she was seeing, however, was that they all seemed to be on the older side. It made sense that there wouldn't be many, if any, first or even second years around now that she thought about it, since this place was apparently for only the worst of troublemakers. Unfortunately, those were the only kids at Hogwarts she could hope to be taller than with her 4 foot, 11 inch (if she was being generous with her measurements) frame, which meant that even though she was probably one of the oldest pupils here, she was also almost certainly one of the smallest. Would that make the others think she was, instead, one of the youngest? The thought made her blush, especially when she realized Madame Wright was still carrying Miss Hoppikins out in the open.

Fortunately, their walk ended not long after that realization as Sierra was led into the infirmary, then back to the nurse's office at the rear. The things she'd brought settled into neat piles on the floor as the door closed behind them, and Miss Hoppikins floated up to the top of a large cabinet to stare down at Sierra as she glanced nervously at her surroundings. Besides the closed cabinet there was a desk, a cot, and an examination table. The latter made Sierra feel anxious, even before she saw Madame Wright pulling on a pair of disposable latex gloves that indicated it might be about to be used.

Sure enough, Madame Wright turned back to her and shook her head. "Come on, now, dear, off with your old uniform. We'd better get you checked out!"

"B-But I feel fine!" Sierra protested, only to gasp as Madame Wright reached over and began to unbutton her shirt.

"That is exactly why you need an examination now, young lady," she said, slapping away Sierra's hand as she tried to rebutton the top button of her shirt. "You had your chance to help! We need to get a good baseline to make sure we know for sure whether you're faking or not if you try to skip class for not feeling well."

"I-I won't do that!" Sierra promised as the woman pulled off her robe and set it aside, then undid her tie and did the same.

"I'm sure you won't," Madame Wright responded, but by her smirk it seemed she had her doubts. Quickly and efficiently, she removed Sierra's shirt, then her skirt, leaving her in her childish, matching, pink polka-dotted bra and panties. "Now, can you take your shoes off for me, or do I need to do that, too?"

"I-I'll do it!" Sierra said quickly, bending down to untie and kick off her shoes, putting them by the rest of her clothes. Madame Wright nodded her approval, then led her over to a medical scale. She guided Sierra up onto it, pulling out the height measuring rod. The top of it jutted out at a 90 degree angle, and Madame Wright twisted it so that it was facing Sierra, then rested it against the top of Sierra's head before grabbing a folder and starting to jot things down.

"Be still!" she ordered, which almost made Sierra squirm more from surprise, not having noticed she was fidgeting impatiently. "Do you have ants in your pants or something?"

Sierra blushed. She wasn't sure when the last time she'd even heard that saying was, especially aimed towards her and not one of the kids she babysat in the summertime! "No," she pouted.

"Well, we'd better check to make sure," Madame Wright said, reaching for Sierra's underwear. Sierra gasped and reached out for them as well, only earning herself another smack on the hand. "Be still!" she snapped again, pulling the girl's underwear off, then continuing with her bra and socks until she was completely nude, just when Sierra had started to feel happy that she'd at least get to keep those things on during this exam.

She whimpered softly, trying to step away from the scale, since standing on it made her feel even more like she was on display here, only to realize that she couldn't. She was stuck there, unable to do anything except what the nurse told her to do, as she was ordered to turn around, then hold out her arms while Madame Wright began to measure what felt like every part of her.

"All right, almost done," the woman said after what felt like hours. "Go hop onto the exam table, poppet."

"But I..." Sierra started to protest as Madame Wright finally removed the height rod. As soon as it was taken from Sierra's head, she could step off the platform of the scale with no problem, though there wasn't much she could do other than what she'd been told.

Even that wasn't right, though. When Madame Wright turned back towards her, she gave a chuckle as she saw Sierra trying to settle her feet into the stirrups at the bottom of the table. "Not like that, dear," she said. Sierra gasped as she saw what the woman was holding, shaking her head defiantly.

"No, not that!" she whined. "I told you, I feel fine!" Deciding this had gone on long enough, she tried to stand back up from the table, only to feel something cold close around her ankles. She looked down, eyes widening as she saw the cuffs that had grown out of the stirrups, shackling her to the table.

They loosened only when Madame Wright approached and grabbed her, flipping her over despite her protests, then fastening around her legs again once she was in the proper position, her bottom now fully exposed and waiting for the Vaseline-coated thermometer the nurse held. She tried to reach behind herself to cover herself, but an impatient wave of Madame Wright's wand later, straps she hadn't noticed at the sides of the table reached out and wound themselves around her wrists. They pulled her down firmly against the table, leaving her helpless to do anything but squeal as the cold glass tube was pushed into her backside.

"Be still, Ms. Nivera," Madame Wright told her, patting her on the rear lightly before walking past Sierra and to the cabinet Miss Hoppikins was now sitting on top of, watching this all. Sierra was doing her best to follow that advice, knowing that no amount of squirming would get rid of the thermometer and even if it did, it would just mean she'd have to start all over. It was difficult to ignore the invasive, cold sensation in her behind, but it turned out all it took was one look inside the cabinet to freeze her in place.

The cabinet was filled with all manner of tools of punishment. There were paddles ranging from fairly small to quite large, some with holes drilled in them, straps, canes, belts and even wooden hairbrushes and spoons. Madame Wright looked them over, glancing back at the horrified Sierra every now and then, just long enough that Sierra began to think that this was just meant to scare her before she finally chose one of the larger hairbrushes.

"I'm not moving!" Sierra squeaked, but as soon as she did she began to wiggle again as Madame Wright closed the cabinet and began to approach the table.

"Oh, this isn't for that, dear," Madame Wright smiled wryly. "You were given very strict instructions on what you were allowed to bring with you. Your little friend is quite cute, and I don't mind looking after her, but I'm afraid I can't abide any breaking of rules here. You're here now because Hogwarts was too lenient and allowed you to do as you wished for too long. Things are different here. Maybe it's for the best that you're learning that right away."

With that, Madame Wright unceremoniously plucked the thermometer from Sierra's bottom and recorded its findings, ignoring Sierra's pleas as she continued squirming on the examination table. She set the thermometer down in the sink, then marched back over to Sierra's wriggling butt. "I do hope this teaches you a lesson, and this is the last time I have to do this," Madame Wright said, patting the girl's pale backside with her still gloved hand. "But to be honest, it is rarely that simple."

Before Sierra could respond, there was a loud smack, and pain suddenly exploded across her left butt cheek. Sierra yelped, tears springing to her eyes as she tried more frantically to escape from the table. She had just enough time for the pain to really sink in before a matching spank was delivered to the other side of her bum. "I-I'm sorry!"

"I hope you are, and your time here helps you learn a valuable lesson," Madame Wright replied. Her next swing was much lighter, making Sierra wonder if she'd gotten through to the woman, but to make up for that mercy, it was followed up much more quickly by the one after, and the one after that, quickly switching sides so that her backside was being evenly warmed.

"S-Stop! I'm s-sorry!" Sierra wailed, helpless to get away from the hairbrush, tears starting to blur her vision. In her thrashing, she caught a glimpse of Miss Hoppikins on top of the cabinet, almost seeming to watch her. Sierra blushed even darker than she already was, remembering the roles her stuffed bunny had played in her duels, which had ultimately landed her here. If only she'd left the stupid toy back with her other things!

Finally, after Sierra's pleas for her to do so had been rendered gibberish by her crying, Madame Wright did stop, walking back to the cabinet to hang the brush back up. That gave Sierra a couple minutes to sniffle to herself, trying to calm down and not think about how red her throbbing bottom must be now. She reached up to wipe her eyes, reaching behind herself to try to rub the pain away, not even thinking about the fact that her hands were now free until Madame Wright stepped back beside her, carrying something new in her hands.

In the midst of everything else, Sierra had completely forgotten about what Madame Wright had said on the train until now. Her stomach dropped and it was only her freshly paddled backside that kept her from loudly declaring that she would definitely not be wearing the thick, disposable diaper the nurse was now holding. Instead, she whimpered, "Y-You don't really want me to use those, do you?"

"Oh, certainly not!" Madame Wright chuckled. "Roll over now, dear. Your punishment is over."

Sierra almost would have preferred her spanking go on a little longer if it meant avoiding this, but when she hesitated, Madame Wright asked, "Do I need to strap you down for this as well?" Sierra couldn't help but remember how easily the woman had flipped her over and the table had held her down last time, and she shook her head.

"Good girl," Madame Wright complimented her as she carefully rolled over on the table. Sierra had only enough time to wince as her sore bottom touched the table before the woman had lifted her back up and slid the diaper beneath it. "There, doesn't that feel better?" Wright asked, and Sierra had to nod. The extra padding did make it more comfortable, and the lotion the woman began to rub into her skin helped, too, cooling her off. She almost didn't think about what it was actually for until Madame Wright began to sprinkle baby powder onto her crotch as well.

"Why do I need that if I'm not going to use these?" she demanded.

"Well, you aren't meant to," Madame Wright replied. "But we have to be prepared, don't we? And we can't have you getting a rash!"

"That's not gonna happen!" Sierra blushed. "I can get to the bathroom just fine on my own!"

"I'm afraid that's not your only concern, dear," the nurse said, massaging the last of the powder into Sierra's skin, then starting to tug the front of the diaper up between her legs, forcing her thighs slightly apart at the bulk. "These diapers are part of your punishment, so you aren't going to be able to take them off on your own."

The thought of being stuck in diapers she couldn't get off by herself, again, made Sierra gulp and fidget, especially since she was just hearing about this as she felt Madame Wright tug on one of the sides of the diaper, making sure it was nice and tight.

"You're going to have to go to a staff member and ask for their permission before you can use the bathroom," the woman continued, pulling open the diaper's tape and smoothing it down onto the front of the diaper. Sierra didn't see anything, but she had no doubt the magic Wright was talking about was happening, ensuring she was now half sealed inside the thing. "A tap of any of their wands on the diaper will unlock it and give you ten minutes to go to the bathroom, take it off, and use the toilet before putting it back on."

Sierra's blush deepened at the thought of having to expose her diaper to her teachers in order to be allowed to use the restroom, but she supposed she should be grateful she wasn't going to have to pee herself, or worse.

"I would keep an eye on the time carefully if I were you," Madame Wright advised, pulling on the other side of the diaper. "If you go over that ten minutes, it will be just as bad as it will if you actually use the diaper."

Sierra's eyes widened at that. "Wh-what happens then?" she asked, feeling very uncomfortable at what it could be, and at not knowing that anything would happen until the nurse's hand was on the final tape, about to peel it away from its backing.

"Have you heard of a Howler?" Madame Wright asked, pausing in her task to watch Sierra warily nod her head. "Well, these diapers are similar. If you try to leave them behind after getting a bathroom break, they'll simply go off indefinitely wherever you leave them, informing anyone nearby that you, Ms. Nivera, are without your diaper, and telling them to report you to me. I'm afraid such a thing would require more punishment. Do you understand?"

Sierra swallowed hard and nodded as Madame Wright pressed the tape against the diaper, locking it shut. "Wh-what about if I use them?" Sierra asked, as if it really mattered at this point.

"I'm afraid the diapers will have to announce that fact, too," Madame Wright replied, sounding almost apologetic. "The only way to make them stop will be to come to me for a change. But I'm sure that won't be necessary, now will it?"

Madame Wright patted the front of the diaper as Sierra nervously chuckled, "O-Of course not," and did her best not to think about the little accidents she'd been having since her duels. They usually weren't too bad, but how sensitive were these diapers? The thought was almost scary enough to cause her to test it out right then and there!

"All right then, enough of that!" Madame Wright declared. "We'd better get you into your uniform and get you off to class!"

"Y-Yes, ma'am," Sierra nodded, sitting up with a crinkle that sounded about as loud as a Howler on its own to her ears, watching the nurse walk off again. She expected the woman to return with a yellow and black uniform, but instead it was green with silver trim. "A-Aren't these supposed to be color-coded for our House?" she asked in confusion.

"Yes, they are!" the woman smiled at her as she started to dress her, not even giving her the chance to do it herself. "Very nicely observed!"

It was difficult to enjoy the compliment when she was looking down and seeing herself in green. "B-But I'm not a Slytherin!"

"Oh, I know that, of course," Madame Wright assured her. "Unfortunately, all of the single rooms in Hufflepuff are occupied, and I thought that, given your condition, you'd want one of those. Am I wrong?"

Sierra blushed. "W-Well, no, but..." Sierra felt confused at that news, fidgeting in place, the sound and feeling of her diaper only making her more upset. "Surely there's more room with Hufflepuff than Slytherin!"

Madame Wright paused in pulling Sierra's sock up her leg just long enough to be noticeable. "And what is that supposed to mean, young lady?"

Sierra stayed silent, not wanting to dig herself in any deeper. She wasn't sure if Madame Wright was a Slytherin herself, or just disappointed to hear that prejudice coming from Sierra, but the woman seemed a little colder as she buckled the Mary Janes onto Sierra's feet, then helped her off the table and pulled the skirt up her legs and over her diaper. It fit, but Sierra knew she was going to have to be very careful how she moved, or she wouldn't need to have an accident to make her diaper announce its presence to everyone around.

"That's not what I meant," Sierra said weakly as the nurse reached down to put the final adjustments on her skirt.

"I should hope not," Madame Wright replied. "That's a very narrow minded way of thinking." Sierra had a feeling there was a lecture building up, but she was spared that by a knock at the door. "Right on time. Here's your wand, that should be all you need for your next few classes. Your things will be in your room, along with extra uniforms and nightclothes. Samara will show you to your classes, and to your room when you have a break."

"Samara?" Sierra asked, right as Madame Wright opened the door to her office, revealing the tall, dark haired girl in green beyond it. Maybe she really was prejudiced, but the girl seemed to have the same look in her eyes as most Slytherins. Even if she hadn't towered over Sierra, it felt like her expression would make it clear she was looking down at her.

It also didn't help that the first thing she said was, "Are you sure she's supposed to come to my classes?", making it obvious she thought Sierra was younger than her, probably by quite a bit.

"Yes, I'm certain. Good bye, Ms. Nivera. And good luck. I hope I don't see you too soon." Sierra knew that last part likely meant Madame Wright didn't want her to humiliate herself by having an accident, but she worried it meant she really had offended the woman, who other than doing her job, had seemed nice enough. She wasn't sure how many other nice people she'd find in this place.

"They let you into Slytherin?" Samara asked doubtfully as they walked down the halls, eyeing Sierra up and down in a way that made the smaller girl nervous that the secret under her skirt had already been discovered.

"Y-Yes," Sierra nodded. She had a feeling that was safer than telling the truth.

Samara shrugged. "What are you in for?"

That, at least, might seem cool. "Duelling," she said as nonchalantly as she could manage. "I started up this underground duelling ring, and they couldn't get me to stop, so they threw me in here."

Samara looked at her again, then nearly burst out laughing. "Yeah, okay, shrimp. Whatever you say. Don't tell me." Then, as if to really make sure Sierra knew the other girl wasn't impressed by her, she asked, "Do you hear that rustling sound?"

Sierra gulped, barely fighting back the urge to tug at her skirt, which might draw attention to it. "N-No," she shook her head. Samara raised an eyebrow, then shrugged as she pushed open a door to a classroom. Sierra followed her into the room of green uniformed teenagers nervously.

She could only hope that Samara would forget about that noise by the time class was over, rather than looking into it, or even mentioning it to any of her friends. Even if Samara didn't say anything, though, Sierra was going to be spending all her time around these Slytherins, who always seemed quick to find any weakness and pounce on it. And these ones were probably even worse than the ones back at Hogwarts! There had to be some reason they'd been sent here! She was trapped in these diapers, which even if she didn't inadvertently show off by walking too fast or moving the wrong way, could announce just how much of a baby she was, should she have an accident. It felt like she had wandered into the belly of the beast, and any wrong move could doom her.

It was going to be a very, very long few weeks until graduation.
