She stopped outside the classroom door to catch her breath, but before she could even wonder if she'd made it on time, Ms. Taylor's voice boomed from inside the room, "You might as well get in here now, Ms. Nivera, you're already in danger of your detention time running into class time."

Sheepishly, Sierra slipped into the classroom. "I'm really sorry, but you wouldn't believe what happened to me last night," Sierra started, unsure how much of her story to tell. It turned out not to matter, since she quickly shut up as she saw her teacher standing there, tapping a paddle on her open palm. Sierra wasn't sure if it was her imagination, or just everything she'd been through so far that day, but Ms. Taylor looked even more beautiful and mature than usual, like her heels her a little taller, her skirt a touch shorter, and her shirt undone one extra button at the top. Standing in front of her in a diaper and crumpled uniform, with the paddle in Ms. Taylor's waiting hand, Sierra felt especially childish, and to her horror, she felt a trickle of pee make its way into her diaper.

After all that work and trouble to keep Ms. Taylor from finding out about her undergarment, that was all it took to ensure she knew all about it. "Sierra Nivera's diaper is wet again!" the garment blared, after such a short amount of time without having to hear it.

Ms. Taylor sighed, shaking her head. "Really?"

"I'm sorry!" Sierra squeaked, blushing bright red. There didn't seem to be any point in denying it, since the diaper itself was all too happy to tell the truth.

"Sierra Nivera's dry diaper lasted six minutes and twenty-two seconds," it informed them. "Clearly she needs them."

"Take off that skirt and let me see," Ms. Taylor ordered. Sierra hesitated, biting her bottom lip, until her teacher smacked the paddle against her own hand with a particularly loud pop, making Sierra scramble to slide the garment off, holding it out towards Ms. Taylor.

Ms. Taylor let go of the paddle, which, rather than falling, floated in the air beside her, and grabbed her wand. She  flicked it to tear the skirt from Sierra's grasp and levitate it over to the teacher, spreading itself out so the woman could examine it thoroughly. "Disgusting," Ms. Taylor shook her head. "Did you leak on this?"

"N-No, ma'am!" Sierra shook her head. She yelped loudly as she felt a smack across her bottom, one so hard that it almost made her forget she was wearing a diaper, except that the surprise of it caused another trickle to make its way out of her.

"Sierra Nivera has wet herself again!" the diaper announced. "Somebody should get her to the potty, if she can make it that far!"

Sierra rubbed her backside, looking behind herself to see the paddle now floating there. When she turned back around, Ms. Taylor was holding the skirt the other way, showing Sierra the back of it, which sure enough did have a couple wet spots, likely from wearing her leaky diaper under it on her way to the nurse's office. Had they been there when she'd been running through the halls?!

"Are you just so used to your diapers that you didn't notice, or were you lying to me?" Ms. Taylor demanded.

"Well, I..." Sierra protested, knowing that the answer was neither, but unsure how to phrase it to keep the teacher from getting more angry at her. Before she could say anything more, Ms. Taylor flicked her wand again and something came flying from the woman's desk, forcing itself into Sierra's mouth. It took a moment before the bad taste hit her, and Sierra's nose wrinkled as the bar of soap in her mouth began to wriggle, then move, seemingly intent on covering every inch of her mouth in suds.

As Sierra wrinkled her nose, trying to spit out the invading soap, Ms. Taylor marched over to her and planted a hand firmly on the girl's diapered crotch. Sierra's eyes widened as she glanced down, seeing the teacher begin to rub her diaper, running her fingers over every inch of the front of the diaper before slipping one inside and feeling there, too. Sierra tried to speak again, but that just encouraged the soap more and it started scrubbing her mouth harder. She could feel the soapy drool starting to drip from the corners of her mouth as her teacher walked behind her and tugged the rear of her diaper out before repeating the process from the front side of the diaper, giving Sierra a very detailed, thorough diaper check.

"Is that all?" Ms. Taylor asked finally, withdrawing her fingers from Sierra's diaper and wiping them on the girl's thigh. Sierra looked at her from behind the still working soap, confused. "Do you need to go more?" the woman clarified. Sierra blushed, but her cheeks only got redder as the teacher continued, "You'd better do it now, young lady. I won't be happy if you pee on my lap while I'm spanking you silly. Go on, wet your diaper like the baby you are."

Sierra whimpered at the mention of a spanking, trying to beg for mercy, which encouraged the soap even more. Her tongue was starting to burn slightly, and the front of her uniform was getting damp from her drool, making her feel even more silly and childish.

Her cheeks burned even brighter as Ms. Taylor reached for her diaper again, prodding the damp spot from the outside. "Is that all? Did you empty your bladder last night when you wet your bed?" Sierra was sure she could see a smile on the woman's face as she squirmed, unable to defend herself and say that she wasn't a bedwetter, as most of her time here had proven. "All right," Ms. Taylor shrugged, tapping Sierra's still yammering diaper with her wand. "If you get so much as one drop on my skirt, you won't be getting your own back after I'm done with you."

Sierra squealed behind the soap, trying to tell the teacher to wait, but the woman was already untaping the diaper, whisking it away. Sierra squirmed, feeling Ms. Taylor's eyes on her, worrying about what she'd been warned was coming next. Ms. Taylor grabbed Sierra by the shoulders, turning her around and examining her back for a moment before reaching out and patting her bottom.

"You're already a little red there, Ms. Nivera," she said. "Were you already spanked, or are you getting a bit of a rash there? Is that why you have so much trouble concentrating in class, young lady? Does that pesky diaper rash make it hard to sit still?"

Sierra still couldn't answer, but even if she could, she wasn't sure she could say she didn't have a rash developing. After the previous night, she did have to admit she was feeling a little itchy. Could she really be getting a diaper rash, like some toddler? If so, she really wished it would have been Madame Wright who'd noticed it, and not Ms. Taylor, who seemed to be having far too much fun teasing her.

With a flick of her wand, Ms. Taylor's chair slid out from behind her desk, settling itself right behind the woman as she sat down, pulling the half-naked Sierra down over her lap and finally plucking the soap from her mouth. Sierra immediately began to plead for mercy, but all that came out of her mouth was a series of high-pitched baby babble and a little drool. She twisted, trying to stare up at her teacher, but Ms. Taylor just pushed her back flat against her legs. "That's much better," she declared. "That soap cleaned your mouth until it was just as good as new. Don't worry, it will wear off, eventually, and hopefully not until you've learned your lesson. Now, hush."

With that, she grabbed the paddle out of midair, swinging it immediately against Sierra's backside, not giving the girl the chance to attempt to say anything more. Sierra yelped and winced, shocked at how much harder Ms. Taylor's spank was than the ones she generally got from Madame Wright. At first she thought it might be because Ms. Taylor was only going to give her a couple, but after letting Sierra whimper and squirm for a few more seconds, the woman began to swing the paddle again, giving each strike enough time to really sink in before moving on. She didn't hit the same spot more than once, which Sierra was grateful for, although she suspected it was more to make sure her entire bottom, as well as the top of her thighs, was nice and pink, rather than minimizing discomfort.

Once that was done, Ms. Taylor ran her hand lightly over Sierra's already sore bum, watching the girl babble incoherently, each goo or ga accompanied by a line of spit, before giving her backside a light pat. "That was a good warm-up," Ms. Taylor nodded after a moment. "Now, let's get on to the real thing."

Before Sierra could process that, the spanking had begun anew. The paddle didn't come down quite as hard, but it was much faster now, and harder to predict where it would hit next. Sierra squealed and wriggled, trying to get away, her cheeks bright red while Ms. Taylor ensured her bottom became so as well. The second, and third and fourth, spanks came so fast that she almost forgot that the first had shocked her so much that she was sure she felt a small dribble running down her legs. There was no mistaking the drool coming from her mouth with every whine and cry, however. She wasn't sure if it was part of the spell that kept her from being able to speak, or because of the soap itself, or just part of her reaction to the spanking, but her chin felt quite wet by the time the paddling started to slow, and by then she was wailing too hard to think much about it.

Finally, the spanking stopped, Ms. Taylor sending the paddle floating away, though only to the top of her desk, where it was still very visible. She patted Sierra's throbbing, swollen bottom gently again, letting the girl stay on her lap for a few minutes before standing her up in front of her, examining her for a moment before taking her hand, leading her to the desk at the front of the room. The normal items from the top of the desk were scooting themselves out of the way, making room for a changing mat and supplies. Ms. Taylor reached over, grabbing a baby wipe just as they landed by her hand, dabbing under Sierra's eyes gently, wiping away the last of her tears.

"Such a sad, leaky baby," she smiled, moving the wipe downward to clean the girl's mouth, clearing away the drool before going even further south. Sierra blushed, staring down at her feet bashfully as Ms. Taylor ran the wipe up her thighs and over her privates, cleaning her thoroughly before grabbing her and lifting her up onto the now fully prepared and stocked changing table. Her bottom sank down into the thick padding of the already spread out diaper she was sat down on. The cans of baby powder and oil leapt into action, dousing her crotch in their contents while Ms. Taylor pushed her onto her back with one hand, so that by the time Sierra was laid back, the teacher's other hand was already pulling the front of the diaper up between her thighs. In mere moments, the sides were yanked up and taped snugly in place, so that by the time Sierra sat back up defiantly, she was already securely diapered. She looked up at Ms. Taylor, still a bit disoriented from the spanking, and the woman just smirked at her surprised expression.

"Well, then, we'd better get your time-out started," Ms. Taylor declared. "You're already cutting it awfully close if you want to be done in time for your final exam." She picked Sierra back up, setting her down on her feet in front of her desk and pointing to the corner of the room by the chalkboard. "Nose in the corner, young lady, and don't you dare try peeking."

Sierra looked down at herself, whimpering at the sight of the thick, bulging diaper around her waist, with nothing to cover it. "Buhgooba," she burbled, frowning and trying to concentrate. She was certain her voice didn't sound quite as infantile as it had when the soap had first been removed, and if she tried hard enough, she could get specific sounds, though calling them words would be far too generous. "Googuhsk... Skoowuh..." She furrowed her brow, knowing she was close, but still not making it. Finally, she reached out and tugged at Ms. Taylor's skirt.

Immediately, as if she'd known all along what Sierra wanted and was just watching her struggle, the teacher asked, "Oh, do you want your skirt back?" She snorted, then shook her head. "We had an agreement, young lady." She reached down, spreading out her skirt to show a very small wet spot there. "Did you even know you peed on me, or are you just that much of a disgusting little baby?"

Sierra shook her head, eyes wide as she fought to protest before finally reaching up and pointing out her mouth. She did vaguely remember a trickle from down below as well, and Ms. Taylor had been sure to clean her there, but had it really been enough to get on Ms. Taylor? Surely it was just from her mouth!

"Are you questioning me?" Ms. Taylor demanded, towering over Sierra, then chuckling as the girl shrank away, burbling an apology. "I'm surprised you didn't have another accident from that," she smirked. "But don't think that means I won't punish you for it. Your time out is extended, young lady, and once it's over you have another punishment waiting for you."

Sierra started to shake her head before quickly stopping herself, sure that wouldn't help matters any. Still, the woman couldn't do this to her! She'd already said there was barely time before the exam, when the rest of the students were going to show up! There certainly wasn't time for an even longer trip to the corner, let alone a whole other punishment! "Nuhmuhtess!" she babbled. "Taytess!"

"If you wanted to take your test with the other students, you should have shown up on time to finish your detention before class. It's hardly fair to the other students for me to let you out of detention early, and since this is your last day here, there isn't another chance for you to make it up. If you finish the last part of your punishment promptly, then there should be time to do the exam as well. At least, there would be time for a good student to finish." She gave Sierra a look that told her in no uncertain terms that she didn't consider the girl a good student. "But the longer you lollygag here, the less time you'll have for that, so I suggest waddling your little diapered bum to the corner right now! And remember, your nose is to stay in the corner!"

Sierra glared at her, wanting to fight back, but realizing there was nothing much she could do. This woman held her academic future in her hands! She had to take this exam, and pass it, if she wanted to graduate, and that meant making her way through whatever awful, humiliating punishment Ms. Taylor wanted to do to her. She stomped her Mary Janes defiantly, then did as she was told, tromping over to the corner and crossing her arms.

This was ridiculous! She felt so humiliated, and silly, and helpless, standing there with the thick diaper between her legs, fully exposed to anyone who might come into the room, her backside still aching from her spanking. She stomped her foot again, angry tears stinging her eyes as she reached back to try to rub her bottom through the diaper. How could Ilvermorny endorse this place, even for its worst troublemakers?!

She jumped a little as she heard a particularly loud laugh out in the hall, squirming and catching herself before she turned her head away from the corner. She knew there was no way they could see her in here through the door, and while that wouldn't last for long, since the early bird students were sure to start arriving soon, she was safe for now.

Or so she thought. She heard footsteps behind her, and then the slight creak of the door's hinges, and suddenly the dull rumble of noise from the hallway became a little louder. She kept waiting anxiously for the sound of the door closing again, fidgeting nervously in place, but it never came.

"We're getting close to class time," Ms. Taylor told her, walking back across the room. "Just had to make sure the other students knew it was safe to come in now."

"Muhbahaychu," Sierra mumbled, blushing bright red as her diaper rub changed to trying to cover the huge diaper with her hands. Now, after everything she'd been through, she couldn't remember where the door was in relation to her corner, but she felt pretty sure it looked right in on her, so that anyone passing by could see her. Now, every giggle and chuckle she heard out there made her even more self-conscious.

She yelped as she felt a light smack on her hands, pulling them in front of herself and fighting the urge to look back and confirm that the paddle had paid her another visit. "There's no need to hide those," Ms. Taylor said. "They suit you very well, and you suit that corner even better. You look like you were meant to be there, and I probably should have made sure you spent far more time there this semester. Maybe it would have done you some good." Sierra tried to move her hands back into place, only to get them whapped again. "I told you no, young lady!" Ms. Taylor snapped. "There's no point trying to hide anyway. Everyone is going to see you and know exactly what happened. I made sure to spank you low enough that some red is peeking out from under your little diaper so they would know about that, too. But as red as I made your backside, I'm surprised that isn't glowing through your diaper!"

The teacher chuckled, making Sierra squirm all the more. Her eye darted away from the wall, catching a glimpse of the paddle floating behind her after all, along with something else, something red, and even though she was very anxiously curious about what it could be, she didn't dare look.

"You know, you are my oldest student," Ms. Taylor continued. "When I heard I was getting you in my class, I thought for sure that I'd have someone who actually understood my lessons. But you were consistently at the bottom of the class, because you refused to pay attention. It was really no surprise to find that you wore diapers. And now here you are standing in the corner in one, after a mouthsoaping and a spanking. You certainly don't look like you're one of the oldest students in this entire building. You don't look ready to graduate to training pants, much less out of school."

Sierra knew the teacher was just trying to goad her into turning around and springing whatever trap was waiting for her there, but even knowing that, it was hard to resist. She blushed deeper, balling her hands into fists and forcing herself to stay still as she heard footsteps approaching.

"I looked into your file to see why you're here," Ms. Taylor said, her voice getting closer and closer. "Honestly, if I were you, I wouldn't go tempting anybody to put me in diapers, because I'd be afraid they wouldn't let me back out. You are just too adorable in them. It's almost like you belong in them, like some big baby doll. I'm surprised none of the many, many people you lost to kept you as one. Oh, wait... One did, didn't she? How much younger than you was she? And how did you free yourself? You didn't, did you? You had to run and tattle on her because you're just a defenseless baby doll who can't do anything for herself. And yet you kept fighting even after that. Were you trying to prove yourself, or did you miss having somebody to change your Pampers for you?"

Sierra jumped as she felt another pat on her diaper, this one clearly by Ms. Taylor's hand rather than the paddle. Sierra gulped, feeling the woman's hand lingering on her diaper as she towered over Sierra. "That's what you ought to think about while you stand here in the corner, listening to the big kids take their exam. Why exactly you ended up here, and whether this is what you wanted all along."

With one more pat on the padding, Ms. Taylor walked away, leaving Sierra blushing and squirming and doing her best not to do as she'd been told, stomping her foot again and mumbling another bit of baby talk that was a little closer to real words than she expected, making her worry that Ms. Taylor might have understood. She knew the woman was wrong, but it was hard to remember that with the words of her diaper, which she'd been trapped in the dark with all night, still echoing through her head, and how it had spent so much time saying she was a baby.

She was almost thankful to have something to distract her from that when she heard another set of footsteps enter the room and greet Ms. Taylor, almost making her turn to see who it was, red-faced. She didn't really have to, anyway. There weren't a lot of teacher's pets in this place, but one of the few was Shelby, who seemed to always have to be the first to class, and always had her hand in the air first for any question, so it was easy to identify her voice. And it was also very easy to tell exactly when she spotted Sierra in the corner, as she let out a quickly suppressed snicker.

Sierra wanted to sink through the floor at the thought of Little Miss Perfect seeing her diaper and spanked bum, and knowing that more people were sure to be showing up in no time. Her only comfort was not knowing whether or not Ms. Taylor had cleaned off her desk. Maybe if the changing mat was still there, people would think it was just part of the punishment, instead of something unfortunately normal for her.

A few minutes later, as the other students started filtering in, they were much less discrete about finding Sierra's position amusing. She tried not to listen too hard as they whispered to one another and laughed, certain that it was her they were talking and giggling about. She fidgeted in place, staring hard at the walls in front of her and wondering how much longer she was going to be stuck here. It sounded like the room was filling up fast, so the exam was sure to be starting, and if she was going to have any hope of finishing it in time, she'd need to get out of the corner and through her last punishment, whatever that was, quickly. Once she aced that test, as she was even more determined to do now, she wouldn't have to see any of these people ever again, so it didn't matter what humiliating position they'd seen her in!

Of course, it was hard to remember that when she could hear them all chattering behind her, certain that she was the topic of conversation. Finally, she heard the bell ring and the classroom door close as Ms. Taylor said, "Quiet, everyone! It's time to get started." Sierra felt a slight rush of magic as the tests flew a stack on Ms. Taylor's desk to all of the students' desks. Sierra had never wanted to take a test as badly as she did right now, but instead, Ms. Taylor walked up behind her. "And as for you, Ms. Nivera," she said sternly. "I don't want to hear a peep from this corner to distract the other students. Not from you, or your diaper." Sierra blushed as the other students giggling and the teacher gave her diaper a firm pat. "I'm docking a full letter grade from your score if you do," she informed Sierra, bending in closer, as if daring Sierra to turn out of the corner to face her. It might have worked, too, if Sierra hadn't been too embarrassed to even think about looking the woman in the eyes right then.

"Quills up, and begin!" Ms. Taylor declared, waving her wand. There was a slight thwipping sound as all the exams flipped over in front of the other students, and Ms. Taylor walked back to her desk, leaving Sierra there in her corner. At first Sierra was grateful that the laughter was replaced with the scratch of quill on paper, as she itched to join the rest of the class, but it didn't take long for her to realize how boring the corner was with nothing to focus on. Every slight movement was accompanied by the seemingly thunderous crinkling of her diaper as time ticked by slowly.

The worst part about the silence was that her mind kept drifting back to the night before, the diaper's humiliating alarm still ringing through her mind as she stood there, squirming uncomfortably. She tried to think past it and go over everything she'd studied earlier in the evening that might be on the test, but she just kept going back to how she'd kept hearing what a baby she was, and how she'd used her diaper, over and over and over.

She let out a small groan, then winced and waited for a moment, sure that Ms. Taylor was going to count that against her, though fortunately the woman didn't say anything after a few tense seconds. How long had it been? It felt like an eternity! How far along were the rest of the students with the test? How much time was there left in the class period? She was desperate to find out, but obviously there was no way to do that with her nose stuck firmly in the corner!

Finally, after what she was sure had to be an hour or more, she snuck a quick look behind her. She turned her head just enough to try to catch a glimpse of the first row of desks, hoping that Ms. Taylor wouldn't notice and that she'd be able to see something. While she couldn't make anything out from the desks, she did see something else far more worrying. She gasped, eyes widening as she spun back into place, shaking slightly.

There, hovering behind her, just waiting alongside the paddle, was a large, red, bulging full enema bag, its white hose slithering around in the air like a snake. Was that what Ms. Taylor was using to make sure she stayed in the corner?! And would it take that little peek as enough justification to attack? She fidgeted in place, suddenly feeling the need to press her thighs together to keep a nervous trickle of pee from escaping and setting off her diaper.

For a moment, she thought she was safe, and then she felt a slight poke at the small of her back. She squirmed, hoping it was her imagination, or something else, and then something slipped its way into the waistband of her tight, thick diaper, slithering down her warm, red backside. She whimpered, reaching behind herself, but no matter how she snatched at the air, she couldn't grab the hose, as if it were enchanted to avoid her hand, not thinking that the movement was likely to be drawing more attention to her plight. She still tried, though, growing more and more desperate as the hose inside her diaper found its destination and suddenly began to push itself inside of her, climbing up more and more as she suppressed a squeal at the violation. This couldn't be happening!

But, sure enough, once the hose stopped moving, it lay still for a moment, deep inside of her, and then began pumping warm water out of itself, gushing out and quickly beginning to fill her up. Sierra squealed, trying again to get ahold of the hose and yank it loose, then, realizing that was doing her no good, and that she would probably be in trouble for making noise anyway, she pleaded, "Mommy, no! Make it thtop!"

She supposed it was better than it could have been, since at least it was probably understandable despite the lisp and how much higher it was than usual, but in the midst of everything, she'd forgotten about that part of this humiliation, her cheeks somehow finding an even deeper shade of red to turn at her childish voice, then again as she retroactively realized after a fresh round of giggling from the classroom that she had said 'Mommy' rather than 'Ms. Taylor', as she'd intended.

"You were given specific instructions, young lady," Ms. Taylor informed her, offering no relief as the water continued rushing into Sierra, making the girl wriggle and whimper. "You were told not to look away from your corner, and not to distract the good students who are actually here to learn. So you will take that nice, warm, soapy enema, young lady, and you will be losing a full letter grade off your test."

"No faiw!" Sierra wailed, kicking at the wall in front of her with her Mary Janes in helpless frustration. The water just kept coming! At first, she didn't dare look behind her to see how much more there was, but then she realized she'd already sprung the trap. What else could it do to her?!

Unfortunately, knowing didn't really help her much, just made her gulp nervously as she saw that the bag didn't look any more than halfway done. Already, she was feeling very full and bloated, and she wasn't sure she could hold anymore, but it refused to stop! She'd had very few enemas in her life, and none this big, and definitely not in front of an audience like this! She'd had trouble holding even the smaller ones for very long, so she knew it was bound not to be long before this one had to come out, too, but that was sure to set off her diaper and get her in even more trouble! And was Ms. Taylor going to make her stay there in the corner until she did it, filling her diaper in front of everyone?! The very idea of it made her squirm in humiliation, as her backside was filled up more and more, making sure it would be harder to hold, and result in a bigger accident. She could feel her tummy start to expand with the soap and water, pushing out against her tightly taped diaper. It made her look even more like a baby, or at least a toddler still holding on to some baby fat!

Finally, just as she was sure she was going to burst, the flow slowed, then came to a stop. The hose began to slither its way out of her, leaving her feeling more full than she ever had before. Her mind felt groggy and her stomach was already beginning to ache as the hose slid out of her diaper, rolling itself up into a coil at the base of the floating bag. How much longer was she going to be stuck in the corner now? She really didn't think she was going to be able to hold all this for long!

"All right, Ms. Nivera, your time out is over," Ms. Taylor said, walking over to her. Sierra turned, glassy-eyed, hardly able to believe it was done so quickly after the enema. Of course, that meant she had to do her test now, in less time than she probably needed, distracted by the huge amount of sudsy water inside her waiting to come out, and knowing there was no way she could get over a B on it, but at least she could sit down and get to work on making sure she was done with this place forever.

Or so she thought. Ms. Taylor grabbed her hand, pulling her over to the chalkboard, Sierra having to take careful, waddling steps to keep up and maintain control of her overly full bottom. Ms. Taylor picked up a piece of pink chalk that looked brand new, which made sense since Sierra was pretty sure she'd never seen the woman use that color, and shoved it into her hand.

"Now, for the final punishment of your detention, young lady, you are going to write lines. I want you to fill this entire chalkboard with, 'I am a baby doll'." Sierra stared at her, hardly able to comprehend what she was saying until the woman reached down and gave her diaper a pat. "Go on, now! You'd better finish filling that board before you fill your diapers."

"B-But..." Sierra whined. "You alweady punithed me! It'th ovew!"

"It most certainly is not," Ms. Taylor informed her. "You still have a punishment coming for questioning my authority, and this is it. Now, I suggest you get to work, and be grateful that I'm only going to dock your grade for talking once."

Sierra shook her head, pointing back at the enema bag, which had followed them across the classroom and landed on Ms. Taylor's desk. "No! That enema wath my punithment fow that!"

"It most certainly was not," Ms. Taylor raised an eyebrow. "That was your punishment for not following my instructions and turning away from the corner. Now, I suggest you get started. Or do you need some more incentive?"

Sierra stomped her foot angrily. "No! That'th not faiw, Mommy!" Her face flushed as she realized her mouth once again failed to say, 'Ms. Taylor', which was much more troubling than even her childish lisp. "And it'th not twue!"

In one smooth motion, Ms. Taylor turned, the paddle, which had also followed them, floating into her hand and allowing her to whack Sierra in the bottom. Sierra gave a loud yelp since even through the thick diaper, the paddle had felt as if she were bare bottomed. If it could do that, there was no reason for Ms. Taylor to have stripped her before her earlier spanking! That only made Sierra more angry, even as she whimpered and fought to hold back the enema after that shock, sure that if she let even a drop go, her diaper would announce it to everyone.

"Fine," she pouted, turning to the board and getting up on her tip-toes to write out, 'I am a baby doll,' in huge letters, taking up the entire board with one repetition. It was still an embarrassing thing to write, but knowing that she'd outwitted Ms. Taylor's awful punishment made it worthwhile.

Or at least it did until Ms. Taylor gave her another spank, making Sierra squeal and struggle again to keep her diaper clean. "Erase the board and do your lines, Ms. Nivera," the teacher ordered. "The longer you play around, the harder you make things for yourself. I'm happy to wait all day, but I doubt you'll be able to."

Unfortunately, Sierra couldn't deny that, so with a huff she grabbed the eraser and wiped out the huge letter, regretting her silly attempt now that she had to undo it. She had to pause halfway, biting her bottom lip as her hands moved to her aching stomach, squirming desperately as another cramp hit her. She fought it back, then returned to her job, hoping Ms. Taylor, or the rest of the class, hadn't noticed.

As soon as the board was clear again, she knew she didn't have any more time to waste. Grabbing the chalk again, she began scrawling the words as fast as she could, just getting the lines out of the way as fast as she could, trying not to think about the words and resisting the urge to ask Ms. Taylor if she was writing small enough this time. She trusted her hand to go through the motions as she tried to prepare herself mentally for her test, trying to review everything she'd spent so long going over in the library the night before, though, just like what happened when she tried before, all she could think about from the previous night was her diaper.

She actually thought she was doing pretty well, making it almost a quarter of the way down the board, when she felt something on her diaper. She turned her head to see the paddle being rubbed against the seat of her diaper, turning slightly more to follow that over to Ms. Taylor's arm holding it. Sierra could barely feel it through the thick padding, but she had a feeling if she hadn't, she would have earned another swat.

Instead, the teacher shook her head. "Do I have to keep an eye on you every second, Ms. Nivera? Are you really so much of a baby that you think you deserve to be the center of attention constantly?"

Sierra furrowed her brow, thoroughly confused. "B-But I..."

"I should be keeping an eye on the other students, just to make sure no cheating is going on, but because you can't show up on time for your detention, or behave yourself like a proper, adult woman, I have to watch you instead." Sierra still had no idea what the woman was talking about, until Ms. Taylor jabbed a well-manicured finger at the board. "This penmanship is horrid, young lady," she said curtly. "And I can barely read this, but it is certainly not what you were told to write."

Ms. Taylor stepped closer to the board, squinting at Sierra's words. Sierra's cheeks darkened more and more as she looked as well, realizing that her thoughts had bled over into what her hand was doing. "'Baby Sierra pee-peed her Pampers,'" Ms. Taylor read out, earning another burst of laughter from the classroom behind them. "Is that true, young lady? And did you really need to announce it as if you're proud of yourself?"

"N-No!" Sierra shook her head, gasping as the teacher grabbed her, turning her away from the board to face her and pushing a hand to the crotch of her diaper, squeezing the padding and then sliding a finger inside of it, just to thoroughly check for wetness. Sierra squirmed and whimpered, wanting to point out that Ms. Taylor knew quite well that she hadn't, since the alarm hadn't gone off, but she doubted that would matter, so she just stayed quiet as she was spun around, the back of her diaper tugged out.

"Look at that, you actually managed to stay clean and dry for once," Ms. Taylor scoffed. "We'll see how long that lasts. Now erase the board and start over, properly this time. I mean it. This is your third try, and I won't be giving you a fourth." She spun Sierra back around, shoving her towards the board one more time, this time, keeping the paddle pressed against her diaper, rubbing and circling, constantly reminding the girl that she was being watched.

If it hadn't been for that, Sierra probably would have stomped her feet and whined about how unfair this was, maybe even launching into a full-fledged tantrum, but knowing another spanking was literally inches away from her made her swallow her rage and pick up the eraser once more. Did she even really have a chance anymore? Having to start all over again was insane when she could feel the enema just begging for a release inside of her.

She had to try. She sighed, shaking her writing hand out a little before taking up the chalk and starting again. This time, not seeing much of a choice, she actually paid attention to what she was doing, watching herself write out the letters and trying to focus on only one of them at a time so she didn't have to fully acknowledge what she was writing about herself, over and over and over, though it was hard not to.

Sierra gasped as another cramp hit her, nearly doubling her over as she struggled to overcome it. "What are you doing, Ms. Nivera?" Ms. Taylor demanded, as if she wasn't fully aware, pressing the tip of the paddle against Sierra's backside a little harder.

"M-My hand hurts," Sierra lied, not wanting to admit the truth. It wasn't a lie, either. She was nearly back to the same point she'd been when she had to erase the last time, so she'd written almost half a board full of the short, humiliating phrase in total, but she still had three-quarters of the board left to go.

"Take as long of a break as you want," Ms. Taylor offered. "But you haven't even come close to filling the board yet, so you'd better hope you don't fill those diapers while you're letting your hand rest."

"I won't!" Sierra declared with as much false bravado as she could muster. She didn't take the teacher up on her offer of a break, however, going back to the lines right away, forcing herself to write faster, even as her hand began cramping up as well. She could tell her letters were starting to get sloppy again, and she wasn't entirely sure if it was more because her hand was getting tired of writing, or if her tummy was distracting her too much.

Ms. Taylor tapped the paddle against Sierra's bottom warningly. "Watch that penmanship, Ms. Nivera," she warned.

Sierra gritted her teeth as another cramp swept over her, her eyes widening when her desperate wiggling didn't seem to have any effect this time. The chalk fell out of her shaking fingers as she pulled away from the chalkboard, clamping both hands to the back of her diaper desperately, pushing the paddle aside as she bobbed in place, biting her bottom lip until, at last, it passed.

"Is someone about to fill their diapers?" Ms. Nivera teased.

"N-No," Sierra shook her head, sweating slightly from her ongoing battle, knowing that she was very close to losing.

"Then hands at your sides," the woman ordered.

"B-But I can't write with my hands..." Sierra started to protest.

"Sides!" Ms. Taylor snapped. Sierra's hands flew away from her padded seat, giving her teacher plenty of room to swing the paddle right across it, making the girl jump as she felt the full brunt of the swat. "You are not to touch my paddle unless you're bringing it to me to punish you with," she said. "Now, pick up that chalk and get back to work."

Sierra gulped as she stared down at the piece of chalk, now broken in two and looking very far away down on the floor. Bending over right now didn't seem like a very good idea at all, but she couldn't deny that it was her fault that she'd dropped it. "C-Can't I use another piece?"

Ms. Taylor, of course, didn't go for that. "I keep my classroom neat and orderly, young lady, I won't have you throwing chalk around wherever you like. Pick it up."

Sierra took a deep breath, locking her gaze on the closest half of the piece of chalk. Carefully, she began to lower herself down, reaching her hand out as far as it would go so she would have to bend as little as possible. Her fingertips brushed against it, just as her tummy began to grumble ominously again. As quickly as she could, she snatched at it, then tried to stand back up.

She felt the tip of the paddle being pressed into her back, pushing her back towards the floor. "Get it all," Ms. Taylor ordered. "It's right over there."

Sierra looked under the desk, where the woman was pointing, seeing the other half waiting there. She tried again to stand up to move over there, but the paddle was just jabbed at her even harder, forcing her down onto her hands and knees. The message was clear. She was to crawl over there on her hands and knees, like a baby.

She could feel the sweat beading on her forehead even more as she did it, knowing that her position would only make it harder if another cramp came now. She felt the paddle slide off of her back, but she stayed on her hands and knees, knowing the threat was still there. Every inch felt like a mile as she scooted along, keeping her eyes on the chalk, grabbing it as soon as it was in an arm's length.

She turned triumphantly, but still very worried, and held it out to Ms. Taylor. The teacher yanked both pieces out of her hand, taking a few steps back, away from her desk. "Come here," she ordered, pointing to her feet, "and let me make sure these are the only pieces."

Sierra had no doubt she was meant to continue crawling, so she obediently did so, blushing as she realized Ms. Taylor was making her come out from behind the desk so that the whole class could see her on her hands and knees. She felt ridiculous, sitting at the woman's feet, and as she glanced up at her after getting there, she blushed as she realized she could see up the teacher's skirt, catching a glimpse of her adult underwear hidden under her skirt, looking far more grown-up than anything Sierra herself had been allowed to wear in a long time.

The teacher was putting the two pieces of chalk together, trying to line up the crack mark to make sure they fit perfectly. How long was she going to drag that out for? Sierra couldn't help but wonder and worry as she made her way over there, still taking it slow, still determined not to...

She groaned slightly as she felt another cramp, followed immediately by an involuntary push. It was small, and she whimpered and fought to keep control, but not before she felt a small squirt escape from her bottom, a small, sticky mess coating the seat of her diaper. She had just enough time to realize what was happen and start to pale before it started.

"Sierra Nivera is going potty in her pants!" her diaper began to wail. "Baby Sierra is pooping her Pampers!"

"Ms. Nivera!" Ms. Taylor snapped, grabbing her and hauling her to her feet, checking her diaper as the class burst out laughing. "Not only did you fill your diaper before you filled the board, you're disturbing the entire class with your little diaper alarm. That's another letter grade, young lady."

Sierra squirmed, both from humiliation and worry. Now a C was the best she could hope for, and that was the worst grade she could get and still pass! She'd have to ace her test, whenever she actually got to take it, if she was going to graduate! "I-I didn't," she whimpered, cheeks burning.

"What didn't you do?" Ms. Taylor demanded. "We can all plainly hear, not to mention smell, what you've done, young lady!"

Sure enough, the diaper was happily still proclaiming the state of itself. Even so, Sierra gulped and pronounced, "I-It'th jutht a little accident! I haven't fiwwed my Pampewth!" She wrinkled her nose, disliking how her mouth had turned, 'diaper' into 'Pampers', or a rather lisp-addled version of that.

Ms. Taylor turned her around, staring down at her patronizingly. "How old are you, young lady?" she asked seriously.

"N-Nineteen," Sierra answered with a blush.

"Are you really arguing about how much you can poop in your diaper before it's considered full?" She clicked her tongue as she watched Sierra squirm. "You really do belong in these things, but we could do without the alarm, since I think we all know what's going on."

Sierra could hardly believe her luck. Sure, it was bad enough that she'd had an accident, however small, and that she was still fighting not to completely lose control here, in front of everyone, but she hadn't expected any mercy from Ms. Taylor! Simply not having to listen to that awful voice reminding her, and everyone else, about it would be wonderful, especially after the night before!

She expected the woman to tap her diaper with her wand as she had before, but instead, she traced a circle in the air with it, and after a moment, the diaper's blaring seemed to get louder, almost echoing in her ears, as the other sounds in the room grew slightly tinnier. "There, now the rest of us don't have to listen," she smirked, stepping in closer to Sierra. "Now go finish filling the board and your diaper, and let's hope you can do the former first."

"Th-Tho I haven't lotht yet?" Sierra asked, trying to find some bright side to all of this, which was difficult with the diaper sounding even more obnoxious now.

"We'll see," Ms. Taylor said. "Either way, I expect you finish your lines."

"B-But why?" Sierra pouted. "If I alweady lotht, why do I have to?"

But Ms. Taylor had already stepped away, shrugging as she looked back at Sierra. "I can't hear you, Ms. Nivera," she said, her voice sounding slightly further away than she actually was. "But I doubt a baby like you has anything important to say anyway. Get writing."

The board still looked woefully empty, and with the diaper loudly reminding her of what had happened, and was threatening to continue happening, in itself, she would have to concentrate extra hard to make sure she kept writing the right words, and that they were legible. "I hate you!" she growled, stomping her foot and glaring at Ms. Taylor, knowing that she was safe from the woman hearing her, at least. She might have continued on her tirade, but instead she groaned as another cramp hit, and the gooey spot in the back of her diaper grew larger before she could stop it. She had to remind herself that Ms. Taylor hadn't come right out and said she'd lost, so she should keep going. That was really the only chance she had of being able to try to do her final exam so she could hopefully graduate.

It was harder than ever to concentrate on her lines now. Not only was the diaper loud and annoying, and no longer just in her memory, but the struggle to keep it clean was getting tougher and tougher, with an periodically expanding icky patch in it to remind her of all the times when she'd failed at that struggle. Those occasions were getting closer and closer together, and every time it was harder to stop them from becoming an all-out accident. Her handwriting was starting to look like a little kid's, but she couldn't help it, and only hoped that Ms. Taylor didn't make her start all over again.

Finally, after what felt like an agonizing hour, she saw something moving behind her. She turned her head to see Shelby walking up to Ms. Taylor's desk. Sierra's heart thumped loudly as she saw the girl hand over her test, already completed before Sierra had even had a chance to start! She could see the girl talk to Ms. Taylor, but she was being so quiet that Sierra couldn't make out any words through her bubble. A few moments later, however, she quickly turned back to the board as Shelby raised her head and looked straight at her before heading in her direction, the teacher standing and following.

Shelby stepped into the bubble, while Ms. Taylor stayed outside of it, but still close enough for Sierra, and the rest of the class, to hear her, even if the sound was slightly distorted. More importantly, it was close enough for her to feel as the woman pressed a hand to the seat of her diaper firmly, rubbing the area to see just how much she'd used the diaper by now. Sierra gulped, biting her bottom lip as she turned to the woman, waiting to see what she was going to say.

If she'd lost, the woman didn't mention it. Instead, she instructed, "I want you to apologize to Ms. Davenport. You distracted her for almost the entire time she was trying to take her test with your immature behavior. I should make you apologize to everyone personally, but since Ms. Davenport here is the first done, she'll have to do."

Sierra's cheeks burned red. She hadn't done anything to this girl! It was all Ms. Taylor's fault! Ms. Taylor couldn't even hear her outside the bubble, so she could say anything, but she had no doubt Shelby would tell on her if she didn't follow her directions to the letter.

"I-I'm sowwy," she sighed. "I didn't mean to dithtwact you, I wath jutht doing what Mommy told me to do."

Shelby smiled and gave her a hug. "Aww, it's all right, sweetie. I just wanted to let you know that my little sister is pretty likely to be sent here next year. I'll tell her to look after you so you won't be all alone in the underclassman dorm, okay?"

Sierra was confused, and more than a little worried about what the definition of 'look after' was meant to be. "I-I won't be hewe next yeaw," she reminded Shelby. "And even if I wath, I wouldn't be an undewclathman."

"Oh, sweetie," Shelby laughed. "Do you really think they'd let you into anything higher than first year after all this?" She pulled Sierra into another hug, squeezing Sierra much tighter this time. Sierra gasped as the pressure finally made her lose the battle, and her bowels began emptying themselves into her diaper, filling them almost instantly as she stood there, mortified, while they kept going. "Just think," Shelby smirked, pulling back away from Sierra enough for the girl to see her face. "After seven more years, maybe you'll finally learn enough to be able to graduate next time around. Maybe you'll even be out of diapers by then."

She gave the now drooping seat of Sierra's diaper a hard swat, then stepped out of the bubble. "Ms. Taylor, she's pooping her diaper!" she reported, loud enough for the rest of the class, and Sierra, to hear.

Ms. Taylor summoned the paddle to her hand, running it along the seat of Sierra's diaper as the girl continued grunting, now completely helpless to stop herself. "Looks like you filled your diaper before you filled the board," she said, making sure not to step into the bubble and obstruct her words. "And you were so close, too! Oh, wait... I guess you're still filling it."

Somehow, Sierra managed to find a deeper shade of red to blush. "D-Doeth that mean I thtill have time to finith?" she squeaked, hurriedly turning back to the board, scrawling out more of the lines. The bottom half of the board was barely legible, but she was nearly done with it. "I can make it!"

"I can't hear you," Ms. Taylor reminded her. "Are you trying to suggest this isn't full enough already?" She made Sierra yelp as she gave the back of her diaper a hard whack with the paddle, one that, just like earlier, ignored the diaper's padding. She kept working anyway, clumsily writing in the final 'doll'.

"Thewe!" she exclaimed, dropping the chalk and turning around desperately. "I did it, wight?"

Ms. Taylor looked at the board, then at her, smirking. "You've failed, Ms. Nivera. Although it is good to see just how strongly you feel about being a baby doll."

Sierra's mouth fell open in shock. The word 'fail' was very worrying to her right now. She grabbed at the teacher's skirt, trying to pull her closer, into the bubble, so she could hear. "B-But I made it!" she exclaimed, squirming in her bulging diaper, not sure when her body had finished its work on that. "Well, almoth anyway."

"You're right," the teacher agreed, smiling down at Sierra from inside the bubble. "You almost did. But you failed at finishing a simple task like that, at completing your detention, at proving you're prepared to be a grown-up, or even graduate from this school. You've failed at everything except filling that diaper." She reached into the bubble, pulling open the back of Sierra's diaper, checking her like a toddler. "At least you did a good job at that."

Sierra squirmed, cheeks burning red. The whole time, her diaper was loudly reminding her, "Baby Sierra has messed her diaper! Stinky Sierra needs a diaper change, badly! Sierra Nivera has badly fudged her Huggies!" making it harder to concentrate, or argue about just how unfair this whole thing was, especially with Ms. Taylor standing there able to hear it all now as well.

Ms. Taylor waved her wand, summoning a copy of the test from her desk. The top of it had a big, red F on it, and as she handed it to Sierra, she saw, in horror, that it had been filled out with the words she'd written on the chalkboard. Even her first attempt, complete with her mistaken admittance of how she'd wet her diaper, was there. The only difference, other than it being on paper, answering questions that, of course, had nothing to do with any of that, was that it looked like it had been written with a crayon rather than chalk. And across the top, looking like it was copied from her line about how she'd 'pee-peed her Pampers', was written her name: 'Baby Sierra'.

"I've finished grading the exam you took ahead of time, so you could finish your detention," Ms. Taylor said, stepping back outside of the bubble to make sure everyone heard now. "Even without the letter grade deductions from your horrid behavior, you failed. Since it would be unfair not to take those into account, I'm afraid I'll have to change your overall grade for this class instead. If you're curious as to what that will be, just take another look at the grade on your test, because they're now the same."

"No! That'th not faiw! You can't do that!" Sierra yelled, stomping her feet angrily. Surely even the other students, as awful as they were, and how much they'd laughed at her that day, wouldn't let such an injustice go! But as she thought back, she realized Ms. Taylor had never mentioned her finishing up her punishments to be able to take the test to them. For all they knew, she was telling the truth, and Sierra really had taken her test beforehand and failed! They had no idea what was really on it, just like Sierra hadn't known that was why Ms. Taylor was having her do lines in the first place!

"I'm afraid I'll be seeing you next year, Ms. Nivera," Ms. Taylor shook her head. Since she was facing the front of the room, only Sierra could see the grin on her face, and she shivered as she thought about what the woman was already planning for her when she returned. "Ms. Davenport, would you accompany Ms. Nivera back to the dorm? I've been informed she has quite a mess to clean up there. I would suggest making sure nobody changes her before she finishes that, just to make sure the punishment sinks in. Have a good summer, you two!"

With that, Shelby happily took her hand, pulling her, still protesting uselessly from inside her soundproof bubble, out of the classroom, away from any hope she had of somehow convincing Ms. Taylor to change her mind and take pity on her. She was so stunned, she barely even remembered that her skirt was still in Ms. Taylor's drawer until she was already in the hall, waddling quite heavily from the drooping, and completely exposed, diaper.

It was a long, humiliating walk back to the dorm, especially with the diaper still playing its insults loudly in her ears. It was hard to think through that, but it was simple enough to recognize how truly unfair the situation was. She hadn't even been allowed to try her final exam, the one she needed to graduate. She'd worked so hard, studying for it! She was sure she could have done it, but the chance had been stolen from her!

By the time Shelby pulled her up to the hallway outside her room and forced her to sit on the hard floor, wrinkling her nose as her bottom sank into the mess around it while the other girl went to fetch cleaning supplies so Sierra could 'clean' the hall where she'd leaked that morning, which already looked perfectly dry to her, she'd made up her mind.

She'd been upset when her father had written and said he couldn't make it to the graduation ceremony, but now she was glad. Since she wasn't graduating, she'd probably be going home, too. She'd have to watch, and make extra sure that any letters from the school, which would probably inform him of what had really happened, got 'lost', while she would tell him she just hadn't wanted to go through with the ceremony if he couldn't be there to watch her.

With any luck, as far as he would be concerned, she'd graduated. As far as she was concerned, the same thing was true. Just because Ms. Taylor had wanted to keep her around to torture for another year, since she'd only had a day to do it this time around, didn't mean that she hadn't earned it. She could try to explain her situation to the Headmistress, but with so many other people there to witness Ms. Taylor telling her version of what had happened, she doubted it would make a difference.

No, she was done with school. She was ready to head out into the real world, and be free of these stupid diapers, and hopefully the stupid spell from the mouthsoaping would wear off soon, too. It had to be better out there... Right?
