"Well, well, well," Sierra's father shook his head, thumping the hairbrush against his open palm. "I am very disappointed in you, young lady. A big girl like you, about to graduate, and you are so immature that you get yourself sent back to first year! Seven years of hard work, and money, down the drain, all because you're too lazy to go to your classes and do your homework!"

Sierra gulped, watching the hairbrush nervously. "Th-That's not it at all!" she sniffed. "That wasn't my fault! It was that Anna girl! She kept me in diapers and..." Her cheeks turned bright red as she thought back to her week under Anna's control, and how humiliating it had been, and how far she'd fallen in just that short amount of time.

"And what?" her father demanded, stepping closer to her. "Made you use them? Dressed you up like a little toddler? Gave you enemas? Spanked you?" Sierra shrank back a little at each, flashes of memories of each of those things running through her head as her dad said them. "Well, you'd better get used to all that, because that's what your summer is going to be full of! Your Headmistress might think you're as mature as an eleven year old, but I don't think you've even made it that far! If you're lucky, by the time school starts again, I'll be convinced you're ready to go back and start again. If not, you'll be staying here. Maybe we'll enroll you in Happy Hills Daycare with all those kids you used to babysit."

"No," Sierra shook her head, vision blurring a little. "W-Wait, no, she just sent me back to first year for a day... Well, a couple, but I'm not actually..."

"Don't argue with me, young lady!" he shook his head, sitting down. "Skirt and panties off and over my lap. Now!"

Sierra shivered and blushed. "B-But daddy.... You don't believe in spanking!"

"I didn't, and look where that got us. I think it's time to start. Now hurry, or it will only get worse!" Sierra whimpered, but slid her skirt down her legs anyway, scared of what would happen if she didn't, pausing for a moment before following it with her panties. After her duel with Olivia, the girl had transfigured all of her even slightly mature looking panties into diapers and forced her to wear them at night. The only ones she'd been left with for the day were ones with cartoon characters, or her set of day of the week panties, which were decorated with cutesy animals. Unfortunately, after her duel with Anna, and subsequent baby treatment, a couple of those had been ruined, leaving her with an incomplete set, which was why she was in the Thursday pair, complete with an adorable picture of a raccoon, despite it being Saturday.

"Good girl," he told her. "Now over my knee."

"Daddy, please!" she whimpered.

He paused for a second, then pointed down at her skirt with the hairbrush. "Get your wand, young lady," he commanded. Hesitantly, she did as she was told. "You are clearly acting too big for your britches, so we're going to fix that. You are going to shrink yourself to the size of the toddler you're acting like, and then you're going to say goodbye to your wand until you prove to me you're ready to start school again."

Sierra blushed. She'd done that in her battle with Anna, and then found herself too exhausted to be able to reverse it until the next day... And even then it hadn't been her that had fixed it, but Anna, and the girl, intentionally or not, had left her an inch and a half shorter than before, just enough to drive Sierra crazy. Of course, she was rather well rested now, so that wouldn't be a problem, even if she was going to be able to keep her wand, but still, she didn't want to spend her summer that size!

"Five..." her father said, leaving her confused for a moment before he continued with, "Four..."

Sierra blushed again. Was he really doing this, counting down like she really was some little kid, convinced that their parents were going to do something awful if they got to zero?

"Three.... Two..."

Sierra began to shiver, fear sneaking up on her despite her best efforts. Even without this, her father was already big and strong enough to do whatever he wanted with her. If he really did intend to keep her in diapers for the summer... Well, maybe being a more appropriate size wouldn't be the worst idea in the world...

"One and a half... One..." His voice grew more threatening as he reached that number, the hairbrush beginning to tap against his open palm again.

"Okay!" she gave in, closing her eyes and casting the spell. She reopened her eyes to find the world looking far bigger, especially her father, who reached down and plucked her up off the floor. She squirmed, dropping her wand as she was draped across her father's lap.

"Good girl," he told her, patting her bare bottom lightly. She braced herself for the hairbrush, but it didn't come. Instead, she noticed the smell of baby powder wafting towards her nose, and then the feeling of her father's large hands massaging it into her skin.

"Daddy, what are..?" she started to ask, feeling confused. "I thought you said...?" She didn't exactly want to remind him of his threat, but at the same time, something just felt off here.

"Don't worry, you'll get your spanking, just as soon as you're taped up into your nice, thick Pampers," he promised. She gasped as she felt a diaper being held to her crotch, a big hand holding it against her bum as she was flipped over onto her back.

Something was wrong here. Well, a lot of things were wrong, really, and the more she thought about them, the more the cracks began to show. She squirmed on her father's lap, shaking her head, confused and scared as she felt the Pamper being drawn up between her legs, then one side being pulled tight. It wasn't until she heard the tape being readied that her mind finally worked through it all, however, and the world swam in front of her eyes, the sight of her living room transforming into the giant nursery where she'd fought Anna, her father changing into Olivia.

In a split second, she recalled what was happening. It was true that Anna had kept her captive as her baby, and not just for the weekends, like the girl had originally said. Sierra had spent nearly a week as the victim of the sadistic girl's strange whims, which had led to her missing quite a few classes, and plenty of homework. Once the headmistress got word of Sierra's absences, she had put a stop to it. Unfortunately, she also decided that because Sierra had failed to alert any of her teachers to what was going on during the few times she had managed to get to class - because she had been too embarrassed to do so - and hadn't put a stop to it herself, which should have been easy with the years of magical training she had over Anna, that she deserved a punishment anyway.

So Sierra had spent a long, dull, humiliating few days as a first year, going over the basics of wandwork and potion making, things that were so deeply ingrained into her from her years at the school that she could do them in her sleep. She'd been forced to sit with them at lunch as well, and even spend the night in their dorm, made all the more humiliating by the Goodnite she'd had to wear because she was afraid Anna's treatment of her might have left her with a bit of a problem. Frankly, it was a good thing, because she'd woken up damp the first night. She didn't think any of the kids had noticed it, but it had been embarrassing anyway, though so was the fact that probably everyone in the first year had seen her suck her thumb, an addiction she'd picked up while under Anna's 'care' that she had yet to cure herself of completely.

She wasn't even sure if that was the worst part of it all. The fact that she had blended in so well with her temporary classmates was pretty troubling as well. She hadn't even been the tallest person in any of her classes. She wasn't the shortest, either, like she was normally, but considering she was surrounded by eleven and twelve year olds, that wasn't much of an achievement. She told herself it was because of that inch and a half she'd lost from the duel, but even with it, she was pretty sure there were still kids who would have been taller.

And it wasn't just her height... None of the teachers seemed particularly surprised to see her there, and while she was sure the Headmistress had told them about her punishment, they still seemed far too comfortable treating her just like the other first years. The only good thing was that she always knew the answers when the professors asked questions, though by the end of the first day she had learned not to raise her hand every time, because she could hear the other kids calling her a show off and a know-it-all, which really stung because she was disguised as a rather stereotypical looking nerd, complete with braces, thick glasses and pigtails. Even knowing that she had a very good reason to know everything they were being taught, and that their opinion of her didn't much matter since she was only spending a couple days with them before moving back up to her regular classes, she still found herself feeling very self-conscious about it, and letting the other kids guess.

She wasn't sure how many of the kids had known the truth about her, but there was one who definitely did. She had even offered to help keep it a secret by coming up with, and helping to cast, the nerd disguise, seeing as the headmistress hadn't gotten Sierra's wand back from Anna when she first began her punishment so she could do it on her own, and pretending she bought the official story of her being a short term transfer from a different school... In exchange for Sierra agreeing to do her homework for her, something she was still stuck with. Sierra was a little worried that, even after she graduated, the girl would find a way to send her homework to her. Of course, by then, the blackmail wouldn't hold as much power, since she would be out of school, but at the same time, Sierra was a little afraid that the girl would somehow send a message to a future prospective employer telling them how the person interviewing for them had, as an Ilvermorny senior, messed her panties while stuck as a first year and had to turn to one of her new classmates for help. Luckily, the girl was the only witness to that particular incident, but even one person was more than she would have liked to know about something like that.

After all that, it was hardly surprising that she had been desperate to regain any shred of dignity she could. She tried to tell her classmates that she had been visiting a sick family member for the past week, but it did not escape everyone's notice that the visiting first year had been there the days she was gone. It could have been a coincidence, and some believed that, but not everyone was convinced. Olivia was chief among them. Her spell on Miss Hoppikins was still ongoing, and once Sierra was back in her own room, she had gone back to diapering her every night with the bunny, teasing her, asking why she hadn't gone to her room to collect some clothes, or, really, anything, before going to visit her relative, not taking Sierra's lame, "I was in a hurry" for an answer.

Finally, Sierra had enough. It was bad enough she'd had to go through the punishment to begin with, or that she was still stuck with the consequences of losing her first duel, with some cocky, self-proclaimed dueling master using her favorite stuffed animal to send her to a diapered early bedtime every night. She was an adult, and she was going to be graduating all too soon. Was this really how she wanted her time at Ilvermorny to end?

Of course not. And so, one night, she had faced down Miss Hoppikins and declared, "I want a rematch." The bunny had stopped in its tracks, staring at her. "Just one more fight," she continued nervously. "If I lose, that's that, and I won't ask for another rematch ever again. If I win, you have to promise YOU won't come looking for a rematch, or any other sort of revenge. And that you'll take the enchantment off of Miss Hoppikins so you can't do this anymore."

"Do what?" Miss Hoppikins teased, growing even further in size than she usually did, towering over Sierra before pushing her onto her back on her bed, yanking her skirt and Sesame Street panties down to her ankles. "Put that cute little butt of yours back in diapers where it belongs every night? I mean, I was planning on doing that anyway once we got out of school - once we're out, I'm sure I'll be too busy with my job and dating and all that to take care of you every night... But when I win, maybe I'll just keep the spell on and peek in on you every now and then to make sure you're all tucked in and diapered at your bedtime. And if not, I guess I'll just have to punish you properly. How's that?"

Sierra gulped as she laid there, letting the stuffed rabbit diaper her. She had been worried that was what Olivia was planning on doing anyway, and while the girl did say that she wouldn't have, there was no actual guarantee of that... The only way to be sure she was safe was to go through with this. "Fine," she said, trying to sound as confident as she could. "Will you be ready tomorrow?"

"I'm always ready," Olivia bragged. "You're the one who needs to prepare. But if you think that's enough time, so be it."

Sierra gave her directions to the room that Anna had set up for their duel, knowing that the girl had a house-elf friend who was maintaining it for future duels. She thought knowing the space would give her an advantage, but, to her surprise, when she arrived, the set-up was completely different. It seemed to have pretty much the same furniture, but it was rearranged, and, to her dismay, Olivia was waiting for her. Sierra wasn't sure if she had done that or not, but it didn't seem to matter much, since she at least had more of a chance to get the lay of the land. Olivia had just grinned at her and said, "Let's do this."

And then, in a matter of moments, Sierra had wound up here, on Olivia's lap, the size of a toddler, wand out of reach, about to lose the fight already. Olivia hadn't even used up any of her magic to do the shrinking herself! She had tricked Sierra into doing it herself and now, just to rub in how weak she was, she was about to put her into a genuine baby diaper, not even having to enlarge it first. Sierra had never imagined the duel could go so wrong, so quickly.

There was no escape at this point. Olivia had her on her lap, and even if she could have squirmed away before the diaper was fastened, she didn't have time to adjust her escape enough that she could feel certain that she wouldn't hurt herself in the fall to the floor. Really, she only had one option, embarrassing as it was, and she only had a moment to try to pull that off. Quickly, she reached up, grabbing the tape out of Olivia's hand, and pressed it to the panel on the front of the diaper before twisting and snatching up the other side to fasten that in place, too.

"Well, aren't you a clever little thing?" Olivia asked, reaching down, hands wrapping around Sierra's hands as she picked her up, lifting her up to her eyes. "Do you really think that's going to do you any good?" As Sierra squirmed in the air, legs kicking uselessly in the air, she had to admit she wasn't so sure. Other than her diaper, she was naked, and while her wand had shrunk with her, thankfully, it was out of her reach. "Pampers are adorable, aren't they?" Olivia mused, setting Sierra back down on her knee. "The only problem is, they just aren't as thick as they used to be. It's a good thing we can do something about that!"

Olivia pressed her wand to the front of the diaper, and instantly the padding began to expand, forcing Sierra's thighs apart while she squirmed worriedly, every passing second making her wonder if she could even walk in her super-sized diaper. "I wonder if that's big enough?" Olivia teased. "Better keep going, just in case... We don't want you to leak all over, and you're quite the heavy wetter, aren't you? Even this size, I bet you'd soak through these in no time!"

The diaper was growing comically big now, which did have one advantage. Sierra wiggled a little, then pushed backwards, letting herself fall off of Olivia's leg and onto the floor below, the diaper absorbing most of the fall quite nicely. Quickly, she grabbed her wand, then shot a spray of water right into Olivia's face as the larger girl bent down towards her. Olivia sputtered, trying to move out of the flow's way, giving Sierra the chance to crawl away.

"Most babies get their nannies wet BEFORE they get their diapies taped on!" Olivia taunted. "You can be a clever little thing, I admit that!" Sierra stopped under a massive crib, not wanting her crinkly pants to give her away. "Come on out, now, Sierra!" Olivia called. "This place is way too big for you! This whole school is! Just come on out, sweetie, and I'll see if I can get permission to take you over to the Happy Hills Daycare... That seems like it would be just right for you!"

Sierra shivered at the thought, but refused to reply, knowing that was exactly what Olivia wanted. She really wished that she had taken a little more time to practice non-verbal spells, since they would come in very handy now. Even trying to shrink her diaper would require an incantation, and she was sure Olivia was listening for just that. Untaping the diaper would be just as bad.

"You can't hide all day!" Olivia said after another minute or two. "Your little bladder can't hold out forever, and as soon as I hear you tinkling in your Pampers, I'll find you! You know you won't be able to hold it for long... Are you going right now?"

Sierra squirmed, only to realize, to her horror, that her diaper did, indeed, feel wet. One of her hands shot to the crotch of her diaper, though she couldn't really feel anything through there. She didn't think she was peeing, though. In fact, the center didn't feel wet at all, though the back did. Quickly, she turned, snatching a baby bottle full of warm apple juice out of the air before it could pour more of it down her pants. Obviously, Olivia could find her anytime she wanted... She was just playing with her, like a cat with an injured mouse.

Sure enough, a moment later, the crib was knocked sideways, revealing Olivia standing above her. No longer having to worry about staying quiet, Sierra used a spell to shoot the bottle right towards Olivia's lips, scrambling out of the way as the projectile flew. "You can't do this to me!" she declared as she went. "I am not your toy!"

Unfortunately, that seemed to give Olivia an idea. "Not yet, but I bet you'd be a pretty cute one! Maybe I won't send you to daycare... Maybe I'll shrink you down even further, until you're smaller than your little bunny without me having to grow her all the time... I can keep you on my bed, and watch you play with Ms. Hoppikins all the time! And then, when I get tired of you, I can give you to my little cousin, Susie. I bet she'd have fun dressing you up! She's a little forgetful sometimes, but I'm sure she'll remember to change you once your diapies really start to stink."

Sierra's path was blocked by a stuffed snake, one that looked awfully familiar. Both Anna and she had used it in their last fight, and even then it had been big enough to wrap either of them in its soft coils. Now, it looked like a monster, one that could eat her in one bite if its teeth were anything more than felt. She raised her wand towards it, but in one bite it and half her arm had disappeared into the plushie's mouth. Stuffed or not, once it had clamped down on her, it didn't seem interested in letting go, and she couldn't do much to stop it as it began to slither its way back towards Olivia, forcing her to crawl along behind, trying to think of a spell she could use that didn't require any wand movement.

Her struggles grew more desperate as she saw Olivia's shape looming, the snake pulling her ever closer, but she couldn't escape before the thing arrived, lifting its head, and her, into the air. She groaned as she was dangled by her arm, allowing Olivia to bend down to inspect her, poking and prodding her. "Hmm..." the girl mused, "I don't think this is quite right."

She straightened, shooting a spell across the room, causing a large doll house to swing open. A whole doll family was inside, seated around a dining table, but it was, of course, the baby that Olivia animated, calling it to her. It toddled over, standing in front of the girl obediently. Sierra wasn't happy to note that it was about the same size as her already, although, like everything else in this place, she knew that was because it was scaled up. It looked up at Olivia, opening its mouth to say, "Mama!"

"Let's see here," Olivia said, reaching down and stripping the doll down to just its diaper, which was, of course, a Pamper. "What do we need to make you the perfect dolly? Let's see... You're way too scrawny, for one! Just look how cutely chubby she is! But we can fix that..."

Sierra looked down in horror as Olivia cast a spell, and she saw her body begin to expand, ever so slowly, her thin arms and legs plumping up, her flat tummy starting to push out against the waistband of her diaper. Desperately, she tried to squirm her way free of the snake, her eyes catching on something in the distance. With a little strain, she managed to twist her hand inside the monster's mouth enough to get it aimed the right way, then fired a spell blindly forward. Thankfully, it hit her targets, sending them shooting straight ahead. Without wand movement, she couldn't give them any more complicated orders than that, but hopefully it would be enough.

Olivia turned to see what Sierra had done, giving Sierra a chance to raise her other hand and push against the snake's jaw with it, allowing her to get it open just enough for her to fall to her feet, just as the toys slammed into Olivia's ankles. It was a tiny zoo, all make of wood and on wheels, various animals made to be pulled around by toddlers - giant toddlers, of course, given that they were scaled up with the rest of the nursery -  but now they were trying to stampede across the room by themselves, not seeming to mind that Olivia was standing in their way.

Olivia had enough time to fire off a spell to pick one of them off, but the others ran into her like a wave and suddenly she was falling. Sierra had been hoping for this, and in an instant, she had launched another spell, this one towards the mobile dangling in the air over them, sending its various strings down to wrap around her opponent's legs while she was vulnerable, then yank her upwards by the ankles while, underneath, the doll she had been using as a model was carried away. Sierra crawled away quickly, her transformed body feeling heavier and more awkward now, slowing her down a bit.

She had hoped that Olivia would be distracted a little longer, but only a moment or two later she heard, "Where are you going, dolly?" Sierra glanced behind her to a collection of Playdough rising from its containers, right before shooting at her like a soft, rainbow colored hailstorm, splatting against her and starting to grow outward to encase her as she made her way across the floor, slowing her down further as it covered her skin. Some of it even made its way inside her diaper. At first, Sierra thought it was just a little, but after a moment, she could feel it start to grow and expand, pushing against her backside and the seat of the diaper, ballooning it outward and adding even more bulk between her legs.

"Uh-oh, is baby having an accident?" Olivia mocked her. "You stay right there, sweetie... I'll be there to change you in just a second!"

Sierra heard a thump behind her that she was sure had to be Olivia freeing herself. What was she going to do?! She needed to buy herself some more time, since once Olivia was free she would be able to catch up to her easily, but what could she do? A plan began to form in her mind, although as she looked around the room, she began to wonder whether she could really pull it off or not. She had spotted the changing table earlier, and knew there was a good-sized stock of baby powder there, along with anything else that might be needed for diapering, and, fortunately, she could see it from where she was. She levitated as many bottles of powder as she could between her and Olivia, then exploded them, creating a huge cloud of white.

*****

Olivia lowered her head and closed her eyes, coughing as the baby powder swirled violently around her for a moment, blindly casting spells to blow it away. If she had thought Sierra seriously had a chance, she might have been worried, since, as long as a single speck of the powder remained on her, the rules of the duel would dictate that Sierra had completed the powdering objective of her victory, but she wasn't worried. She had watched Sierra try to put up a fight against Anna in her room, had seen her studying, struggling even more than most of the students who grew up in the Muggle world. She was no match, and while it was cute that she had somehow thought she was, this match was starting to get old.

Luckily, Olivia opened her eyes before raising her head, giving her a glimpse of the puddle of white spread out in front of her, the empty bottles scattered throughout indicating that Sierra had emptied out the bottles of baby lotion as well as powder, trying to lay a trap for her. "Nice try, dolly," she called. "You shouldn't waste all of your changing supplies, though! You're going to need them!" Still, she had to admit, the powder had done its job, and she reached up to rub her eyes, trying to clear her slightly bleary vision.

She turned quickly as she saw something moving from the corner of her eye, smirking at the sight of the baby trying to crawl under the changing table to hide, obviously having been looking for something else to try to use as a trap. Her skin was completely covered in the Playdough now, the diaper straining to remain fastened.  With a smile, she silently cast another spell, causing the dough outside of the diaper to begin to harden, preparing another something as she saw her opponent's actions slow down even further.

"I've noticed," Olivia mused as she moved towards the changing table, "you're not very good at non-verbal spells, are you? You should have learned those last year, but I guess I shouldn't be surprised you still haven't caught on. You're a bit slow with magic in general, aren't you? You just aren't very good at all! I wonder what you'll do if something like this happens?" She launched a pacifier towards the girl, sending it flying straight into her mouth. It wasn't just a normal pacifier, though... She had used it a couple times before on Sierra, to fun effect. Knowing she had a duel coming up, and deciding to be prepared just in case, she'd had a house elf prepare a nice, big batch of oatmeal and keep it ready for her in a specific spot in the kitchens. She'd made a large hole in the nipple of the pacifier and then linked the inside of the nipple to the bottom of the pot of oatmeal, then used a sticking spell around the inside of the mouth guard, just in case Sierra managed to break an arm free.

She hadn't by the time Olivia crossed to the other side of the changing table, and was, in fact, stuck there, diaper bulging, tummy being filled to prepare her to make a more genuine mess in her Pampers later. "Come on, playtime's over!" Olivia announced, bending down to pick the girl up, laying her down. She almost felt sorry for her when she saw that the Playdough had even spread out over her face, holding her eyes shut. She hesitated, almost clearing that away so Sierra could see herself being defeated, but she was sure that was something the girl had seen plenty of times before, and she was just ready to get this duel over with now.

"Looks like you had a little too much fun today!" she teased as she reached down to undo the diaper tapes, annoyed that the Playdough had splattered over one of the tapes. Sighing, she tucked her wand into her robes, then began to clear the stuff away so she could get the diaper off to put a new one on. "I think you're going to need a nice, long bath later! A nice, long, soapy bath... And we might as well give you a nice, big, soapy enema, too, to clean out your naughty little insides, too!"

Finally, she managed to get the diaper open, but the mess inside, while not being hardened, was still quite formidable, and she couldn't help but regret having been so enthusiastic with that particular spell. Finally, after pulling a good bit of it away, she decided to give up, assuming she would still win as long as the powder was in the diaper... And if not, she would just try again. It wasn't like Sierra was going anywhere. She could finish cleaning the girl up later, or make her do it herself. "Here's a nice, fresh Pamper for you!" she chanted. "It's not as thick as your last one, but I'll fix that in a minute, cutie!"

Her opponent was helpless to do anything as she lifted her up, sliding the diaper underneath, and then sprinkling a liberal amount of powder onto it. She paused, looking down at the girl's hidden face. The dough hadn't covered her nostrils, so she could breath, but that was about all that could be seen, and it just wasn't quite as satisfying, not being able to hear her beg for mercy, or look up at her with her big, scared eyes. Her hand moved up to the girl's face, carefully breaking away a part of the stuff coating her, freeing her mouth. Through her blurry vision, something seemed wrong, but she couldn't quite place it, and tried to shrug it off. "Any last words?"

There was only one, though it told the story well enough. "Mama," her victim said, in a voice that was definitely not Sierra's. Quickly, she reached for her wand, but it was already gone, and in a moment, her robes were swirling around her, wrapping her up and dragging her off her feet and over to the dollhouse. Sierra stepped out of it, naked except for a few bits of Playdough still clinging to her skin and a Pamper, clutching her wand. Olivia's own wand, much too large for her to try to use effectively, was on the floor next to the house. As Olivia watched, struggling to free her arms from her own clothes, the stuffed snake slithered next to her, adult diaper in its mouth.

"Any last words?" Sierra smirked.

****

It had been simple enough - so much that Sierra had worried Olivia wouldn't fall for it.In the confusion of the powder cloud, she had scrambled to the dollhouse and summoned the doll Olivia had been using as a model, pulling off its diaper and putting her own on it before scraping off as much Playdough as possible from herself and putting it on her decoy.  She'd felt a little nervous when Olivia had so quickly blown the cloud away, leaving her anxiously spreading the Playdough over the doll, but fortunately, she'd managed it in time, sending it off to crawl towards the changing table.

She'd pondered whether or not to bother putting the doll's diaper on, but in the end, she'd decided it was for the best, just in case Olivia noticed her hiding there and her nudity gave her away. Part of her disliked the idea of posing as a doll, after everything Olivia had said to her, but part of winning a duel, it seemed, was using whatever was at your disposal, and Olivia had done her best to make her look like a doll. As soon as Olivia put her wand away, she had began working on it, slowly pulling it free of her pocket, letting it slowly drop through the folds of her cloak, then hiding it under the changing table until Olivia noticed she had been tricked, summoning it over to the dollhouse while the robe was dragging Olivia to her.

Sierra had to admit, all the casting was taking a toll on her, but she was almost done now. It was easy enough to yank down Olivia's skirt and underwear to around her ankles, and from there, she could levitate them and take Olivia's legs and backside with them. Just to make sure Olivia didn't wriggle free, she had the snake wrap around the girl, further encasing her arms, before laying down the diaper beneath her bottom. Sierra let the levitation spell fizzle, knowing the fluffy diaper would help cushion its fall, then, as she walked over to her prey, she had the snake reach down to grab the front of the diaper and pull it up over Olivia's crotch.

"No! You can't do this! This isn't fair! You're not strong enough to beat me!" Olivia raged impotently, her struggles only causing the snake to coil around her more tightly. Even so, Sierra was nervous to get too close, but she didn't have much of a choice, since she had to tape up the diaper by hand to win. Being careful to approach from the side to avoid the larger girl's flailing legs, she yanked one side of the diaper up and clumsily stuck the tape to the front before crawling over Olivia and repeating the process on the other side, heart thumping wildly, hardly able to believe what was happening any more than Olivia apparently could.

Sure enough, though, she heard a distant click signaling the doors had been unlocked. The duel was over. And, against all odds, she was the winner!

Olivia's legs continued to kick, though they looked more like a tantrum rather than defiance now. "Oh, you little brat!" she yelled. "This isn't fair! It doesn't count!"

"Doesn't it?" Sierra asked, stepping away and letting her enchantments on the clothes and stuffed animal drop. "Try it and see."

Glaring at Sierra the whole time, Olivia struggled free of her bonds, then reached down towards the diaper, trying to pull it off. Thanks to the rules of the duel, however, since the victor had put it on her, her hands just slid uselessly off of them, leaving her trapped. Now she couldn't remove any diaper Sierra put on her without help from someone else.

"Now, why don't you go ahead and do what you promised?" Sierra asked, kicking Olivia's wand over to her. "Take the spells off of Ms. Hoppikins. And fix me, too."

"Fine, fine," Olivia glowered, uttering a few spells. In a moment, Sierra could see the nursery seeming to grow smaller around her. She smiled, looking down to see herself getting bigger, the baby fat that had been added melting away before her eyes. The Pamper's sides stretched, but, somewhat embarrassingly, managed to hold on, if just barely, making Sierra wonder if she actually could fit into them normally, since these weren't even the biggest size, though she hoped not to have to find out. By the time it was finished, she almost thought Olivia had overshot her goal, before she realized that what had happened was that she was back to four feet ten (and a half, of course) inches, rather than four foot nine, which she had been stuck at since her duel with Anna. "Now what? You want to parade me around as your baby and humiliate me?"

"I'm not that mean," Sierra shook her head. "Besides, you were at least always good about keeping things private between us... And I don't really have time to take care of a big baby with exams coming up." She smiled as she saw the look of relief wash over Olivia's face, right before she reached out and snatched her wand away. "On the other hand, you were talking about putting me in daycare, or turning me into your cousin's doll..."

"That was just a joke!" Olivia insisted, although Sierra wasn't so sure. With a few flicks of her wand, she had stripped Olivia down to her diaper, and summoned an adorable sleeper from one of the room's closets. She'd seen it there during her last duel, though she had luckily not been put into it. Considering how Olivia had used Sierra's stuffed bunny against her, though, it seemed quite appropriate.

"Hop on in," she joked as she held it out for Olivia, threatening her with her own wand when she didn't move fast enough. Sierra pulled it onto the girl, zipping it most of the way up, then dropping Olivia's wand inside before pulling the zipper the last couple inches, getting up on her tip-toes to pull the hood over Olivia's head. It was pink and white, and quite fluffy, modeled after a bunny, of course. It had built in feet, mittens, and a hood, with floppy ears sewed to the hood and a big tail on the rear. There was a zipper going down the front, but, as Olivia watched, it began to vanish into the fabric, leaving her pawing after it helplessly.

"Don't worry, it'll come back," Sierra reassured her. "But only once you've used your diaper. Actually, let me rephrase that... Only once you've filled your diaper. I mean, I'm not very good at magic, so I couldn't figure out how to get it to detect just one use, so the spell only kicks in once you start leaking into your PJs. Of course, even once the zipper can be used, I'm not sure you'll be able to grab it with those mittens... And even if you can, you aren't getting that diaper off without some help. I'd offer to do it, but like you mentioned, I'm not strong enough for all this, so I need to go take a nap. I'm sure you'll find somebody to help you, though! Oh, and one more thing... Since you're so good at nonverbal spells, I bet you're pretty good with wandless ones, too, so to keep you from trying anything..."

She summoned a large, pink pacifier gag, pushing back the hood long enough to lock it into place. She gave Olivia one last triumphant smile, then reached down to grab the girl's clothes from the pile she'd flung them on, shrinking them to fit herself. She pulled the stretched out diaper off and tossed it aside, then got dressed, trying to ignore the fact that her spell hadn't completely worked, leaving her still looking a bit like a little girl playing dress up, and marched out of the room.

She managed to contain her fist pump and squeal of excitement until she was down the hall. She really did need to go take a nap, one that would quite possibly last until the next morning, but that didn't matter. She had done it. She had finally won a duel! Part of her thought about giving up, that just doing it was good enough to prove that she wasn't the baby everyone seemed to think she was, but on the other hand... If she could beat Olivia, supposedly the best duelist in the school, then who knew what else she could do? She had to admit, winning had been quite a rush, and if she could do it once, surely she could do it again!

For the first time in a long time, she flopped down onto her bed in panties, knowing that she would be waking up in them and not a diaper, feeling confident enough in herself that she didn't worry about the fact that she had been waking up wet every now and then lately, or her thumb slowly drifting upwards towards her mouth as she drifted off, which was also getting somewhat common. She could worry about those things later. For now, she was a champion.
