Sierra adjusted the bag on her shoulder, squirming anxiously as she looked around, feeling suddenly alone as she made her way into the park. It was nice, in a way... Things had been so busy as school ended, especially after all that drama with Anna, that it was nice to have a chance to just relax with her Muggle friends. She was sure it was going to be a great time! Even if her friends had already abandoned her...

That had really been her choice, though. They all wanted to start out with the roller coasters, which made sense, she supposed, since those lines tended to get pretty long pretty quickly, but she hadn't wanted to go, claiming she didn't like coasters. She wasn't a big fan, but mostly she was just nervous that she would be too short to be allowed on the hardcore ones that her friends wanted to ride, and didn't want to go through that humiliation in front of them. So, instead, she'd decided to start off at the water park while they did that, then, once they were finished, they would call her cell and meet up with her in there.

Almost as soon as they'd rushed off their own direction, however, she'd realized the flaw in that plan - she couldn't have her cell with her in the water rides. It was going to have to stay in her locker with her dry clothes and towel and such. Not wanting to seem like a worrywart, she'd let it go, figuring they would be able to find her, or she could just take a break to check her phone after a little while. No big deal!

Except that she had yet to actually find the lockers. She was starting to suspect that, in her excitement over first entering, she'd walked past them without noticing, because she was sure they had to be somewhere. She was beginning to regret her choice not to bring her wand, though, of course, she couldn't really have used it without everyone seeing. It was quiet enough now that she might be able to use a guiding spell without being too conspicuous, though.

She needed somewhere to change into the swimsuit she'd brought, and to stow her phone and cash, having left her credit card at home to make sure it didn't get stolen or anything, and to limit her spending. It was all tucked away neatly in her bag, which was starting to feel bigger and more cumbersome by the minute as she tried to figure out where she was meant to put it.

Perhaps more importantly, she needed a bathroom. Her bladder control still wasn't quite 100%, and it had been a long car ride, so she had "borrowed" a Pull-Up from the little girl she had babysat the night before and worn it. It had been embarrassing to note that she didn't even need to use any enlargement spells to fit into it, and even more to get into Ashlynn's car in it. She was pretty sure nobody knew, though, and despite a couple close calls, she had made it to the bathroom every time they stopped without any incidents. Now she was starting to get a little worried, however. If anything did happen, she did bring a pair of red Elmo panties to change into once she was in the park, but she would still have preferred not to have to use the Pull-Up.

It was still early enough that there weren't even many people around for her to ask, and those who were there were already taking advantage of the rides. Finally, she went over to the edge of one of the pools, bending over to shout to someone relaxing on an inner tube somewhat close to the edge. Before she could get it out, however, the person yelled, "Look out!"

She turned right in time to see a pair of girls, probably around fifteen, and rather tall, running along the edge of the pool, quite unsafely, but, more importantly, right towards her. Anxiously, she tried to step out of their way, only for her foot to slip. With a yelp, she fell right into the water, bag and all. Sputtering, she hastily scrambled back out, but it was already too late - she and everything she'd brought with her was soaked. She stood there, stunned, on the brink of tears as she began to wonder what she was supposed to do now with her money all soaked and phone wet as well, keeping her from being able to call her friends for help. The teenagers just giggled and hurried along, not making any move to assist her even though this was their fault.

"Oh goodness dear look at you! Soaked to the bone!" A strange woman looked down at the sopping wet Sierra; in her red dress and sunhat she held a large pink bag at her side. In her other hand she held a towel which she draped over Sierra.

Sierra looked up in surprise at the sound of the woman's voice, still a little in shock over what had happened, and how quickly, not quite able to react as she was pulled to her feet, nose wrinkling as her feet squished against her soaked socks and shoes. This was definitely not the way she had expected her day to begin.

"Let's get you to the locker rooms and into a new pair of clothes before you catch a cold." With that the woman ushered Sierra towards the locker rooms before she even knew what was going on.

By the time she had calmed down enough to think, they were already halfway there. The lockers turned out to be, as she'd expected, quite easy to spot now, making her feel quite silly for having missed them the first time.

"Th-Thanks," she said with a blush, also feeling rather silly at having had to be 'rescued' by some random woman. "I don't really have any extra clothes to change into, though... I had all my stuff in my bag!" She pouted as she looked down at it, cursing her luck. If only she had her wand, that would be no problem, but stuck as a Muggle for the day, she was all but helpless in the face of such rotten luck.

"Don't worry dear we'll have you cleaned up in no time, and I have an extra outfit in my bag here. Now, let's get you out of those soaking-wet clothes."

"Oh, that's nice of you, but you don't have to do that..." Sierra said half-heartedly, though she was glad the woman didn't seem to pay her any mind, since, otherwise, she wasn't really sure what she was going to do.

Once in the locker room, the two were alone to themselves, and the woman sat Sierra down at a bench, taking the towel and quickly starting to rub the girl dry.

Sierra had to admit, after the chaotic start her day had gotten off to, it was comforting to feel the woman drying her off, taking care of the mess she'd become. She even found herself closing her eyes, although they snapped back open as she felt the woman begin to undress her, dumping the clothes off to the side.

"I-I can do that myself," she protested bashfully, trying to squirm away, growing much more desperate as she saw the woman reach for her pants.

It was already too late, however, the woman's hand already unbuttoning her pants and pulling them down, exposing the Disney Princesses emblazoned across the front of the soaked garment.  "Hmm, care to explain these dear?"

Sierra turned bright red as she felt the woman's hand give the sodden padding a good pat, a little of the water they had absorbed getting pushed out by the motion. "I, uh... I..." she stammered, not sure what to say. "I don't need them!" she blurted out finally, figuring that was the most important thing to establish. "It was just for the car ride!" She blushed again as she realized how that sounded, trying and failing to think of some better way to explain it before clamming up and staring down at the floor, cheeks blazing.

"Oh, you don't need them?" The woman grinned, "Hmm, they're awfully wet for that... Well you may not need them but you certainly want them, don't you? Such a naughty girl."

"What? No! I-I just fell in the pool, you saw me, it isn't my fault!" Sierra squeaked in surprise at the woman's implication, blushing as she was called naughty. She had certainly felt naughty when she'd put them on that morning, remembering how she'd stolen them, feeling like her many babysitting charges whom she had seen in those exact Pull-Ups, or like she had that week she'd been stuck under Anna's care. She'd felt like a silly, naughty little kid...

But not nearly as much as she did now. She gulped as the woman pushed her back onto the bench, unsure what was happening, feeling helpless before the larger woman, especially with no dry clothes of her own to change into if she offended this person who had offered her some. The woman searched through her rather large pink bag, seemingly going through a large assortment of items hidden away in there. "Well, they're not exactly pullups, but I think they'll do the trick."

She teasingly waved the large diaper in front of Sierra, all nicely folded and crinkling, "Now, let's get these soaking Pull-Ups off and get you diapered!"

Sierra's eyes widened as the woman pulled out an all too familiar garment, one she had hoped not to wear again for a long, long time. She tried to sit up right away, shaking her head in fear. "No! I can't wear that!" she yelped, even as her Pull-Up squelched wetly beneath her. "L-Look, I told you, I don't need these," she poked at her Pull-Up, "and I definitely don't need that!"

"I think otherwise, nobody puts on a Pull-Up for no reason. And you don't have a choice either way; your clothes are soaked and no one else is going to help you out, so this diaper is going on you one or another," the woman sternly warned. "Now, be a good girl and let me take those pullups off or else they'll be the only thing you'll be wearing out of this locker room."

Sierra's cheeks turned a little redder, not wanting to explain things for fear of sounding even more like a little kid, and doubting it would make much of a difference anyway. The woman seemed to have made up her mind, and Sierra had a bad feeling that she was right - she doubted anyone else would be along to help her, not until her friends caught up with her later that day, anyway.

She could only squeak nervously as the woman pulled off her wet Pull-Up and tossed it aside, feeling embarrassed to be lying there, naked, in the locker room, in front of this person she hadn't even introduced herself to. It was far better than going outside in the soaked thing, though, so she blushed and forced herself to bear it, though the sight of the diaper still scared her a little.

She gasped as she felt her backside being lifted, then lowered into the padding with a crinkle, squirming even more as she realized she was getting diapered yet again, this time not even by another witch, just some Muggle. "Please don't do this...." she tried one last time, knowing the end was near.

"Now now, you asked for this the moment you put on those Pull-Ups, now hold still," the woman commanded, powdering Sierra with a very liberal amount of baby powder.

"Did not," Sierra whimpered weakly, watching in horror as more and more baby powder was sprinkled onto her crotch, leaving it a sea of white and filling her nose with the unmistakably infantile smell. Each shake only seemed to weaken her, making her realize more fully  the hopelessness of her situation. She managed only one more squeaky, "No!" as she felt the padding being tugged between her legs, forcing her thighs apart, and then it was done.

The diaper's padding was inescapable, crinkling and pushing against her tender skin from every angle as she squirmed on the bench, dazed by what was going on. Rummaging through her large bag again, the woman pulled out several articles of clothing. "Now, hold still while I dress you." She held some pink legging shorts..

"I-I can dress myself!" Sierra protested, not wanting to give this person any more of a chance to put things on her, unsure what those might be. Before she could stop her, however, the pair of leggings had been yanked up her legs and snapped into place, leaving her blushing even deeper. They did nothing to hide the bulge of her diaper - in fact, if anything, they emphasized it, and forced the padding even closer to her body, making it even harder to ignore.

"St-stop!" she commanded, trying to sit up, though the size of the diaper, and its unfamiliar feel, made that hard. "This isn't funny! I am not a baby! You can't do this to me!"

"Oh, I think you are a baby, or at least you wanted to be treated like one."

"I do not!" Sierra whined, managing to sit just in time to give the woman a chance to slide a dress over her head. She blushed as she looked down at it and realized just how silly and childish it looked with its watermelon shaped collar and red and white checked pattern on the rest of its short length, bottom hem held up by a green ribbon at the bottom that was punctuated with a large bow. It would have looked adorable on a little kid, she had to admit, but on her it was just humiliating.

The woman smiled, making sure the dress was snug and secure in all the right areas. After that she pull out a pair of pink Mary Janes and frilly white socks. In no time, while Sierra was busy taking in the dress, the woman had the socks pulled up and the shoes buckled on. Before Sierra could properly react, she was fully decked out like a (slightly) overgrown toddler.

"There, now you look like how you act -- a big baby." She commented, taking the wet clothes and putting them in a plastic bag and storing them in her bag. Sierra couldn't really deny it, though it was obviously the woman's fault. "Now, if you want these back you'll have to be a good little girl or else you'll be in some big trouble little missy, is that understood?"

"This isn't fair!" Sierra whined, hopping down off the bench clumsily and reaching for her clothes as she saw them vanishing into the woman's bag. "You can't take those! They're mine! You can't do this to me! I look ridiculous!"

"Clearly you are unable to properly take care of yourself, so you're going to be spending the day with me, and then we'll get you back to whoever you came with, and they can see how much of a big baby you are."

"I can take care of myself!" Sierra started to fume, only to be distracted as the woman pointed at her lap in a worryingly familiar way

"Of course, I also don't take kindly to rude little girls as well."

Sierra's cheeks turned their brightest shade of red yet at the thought of her friends seeing her like this. "You can't do that!" she said, half demanding, half begging.

Despite being one of the oldest among her group of friends, as the smallest, by quite a good deal, and, even by her own admittance, one of the most immature, preferring to spend a summer Saturday night watching cartoons rather than going out and clubbing, she was often treated like the youngest. Sometimes, she thought her friends saw her as a little sister, one who tagged along because she wanted to hang out with the big kids, even though she was older than most of them. She was sure she'd never live down any of them seeing her like this.

"You can't do that!" she repeated only a moment later, even more desperately, as the woman tired of waiting and pulled Sierra over her lap. Sierra was once again at a loss for words as she realized she was about to be spanked, having only a moment to process that before she felt the first smack. Through the thick diaper, she didn't expect it to hurt that much, but the woman seemed experienced enough to accommodate for that, and Sierra let out a yelp at the sting that the first smack brought.

There was just enough of a pause that Sierra thought that might be it, and then the woman began again in earnest, leaving her squeaking and squealing and squirming as the blows rained down on her padded bottom, blushing as she realized she was receiving an honest to goodness spanking, the embarrassment almost as bad as the pain, at least at first. Before long, though, her stinging backside was almost all she could think about, and her struggles slowed, other than her legs helplessly kicking as she tried in vain to stop the punishment. She had never spanked a child in her life, but she had reported bad behavior to some's parents that she knew would result in one, if they were very bad, always when she felt they truly deserved it... And now, here she was, getting one herself, when she was just as certain that she didn't.

"Stop, stop, I'm sorry!" she yelled, crying, sure that, beneath her diaper, her bottom was just as pink as her leggings, knowing that, at any moment, someone else could walk into the locker room. "Just stop!" The woman seemed determined to spank her silly, however, and it became difficult to talk as she worried that she was about to wet the freshly taped-on diaper just moments after being put in it.

Finally, the woman gave one more hard swat and stood Sierra up. "I hope that will teach you to show an adult proper respect."

Sierra wanted to indignantly point out that she was an adult, so she should be getting proper respect, instead of being treated like a little kid, but she was too busy whimpering and rubbing her bottom. While the woman's spanks had gotten through the diaper just fine, the rubbing did not, giving her no relief from the pain there.

The woman once again reached into her bag and pull out a red child harness, "Now, I was going to let you just hold my hand, but after that fit I think I'll take a few extra precautions here."

Sierra began to shake her head at the sight of the harness, knowing quite well what it was, but she was still sniffling and shaken from the spanking, slowing her down enough that the woman was able to slip the straps over her, making sure they were tight and secure, attaching Sierra securely to her.

Then the woman got the leash and clipped it on, "Come now, we're going for a nice walk around the park."

It suddenly became all the more real just what this woman wanted to do to her. In the locker room, it was bad enough, but, somehow, it hadn't really seemed possible that she was really going to make Sierra leave there like she was. Now, her doubts were quickly wilting away, leaving her with a horrible feeling of certainty in the pit of her stomach.

"Come on, no..." she pouted, looking down at herself. "You can't let people see me like this! Just let me have my clothes back, and you can have these... I'll wait here for mine to dry!"

"I don't think I want those back," the woman sneered, giving the crotch of a diaper a good smack. Sierra blushed as she felt a small wet spot there and realized she hadn't been quite as successful at containing herself as she'd thought. "Do I?" When Sierra couldn't bring herself to answer, she shook her head and said, "Then I won't hear another word of complaining, come along now!" With a tug the woman pulled Sierra closer, making sure she kept up with her pace.

Sierra gasped as she was pulled back out into the sunlight, exposed to anyone passing by. Her cheeks turned bright red and she stared down at her pink shoes, giving herself a good view of the thick diaper above them, emphasizing her position. She had no choice but to follow the woman, the diaper giving her walk a very pronounced waddle.

At first, she worried that would make it hard for her to keep up, but it didn't take long for her to realize that was the opposite of what the woman had planned, her pace quite slow and deliberate, making sure everyone could get a good view of the adult-turned-baby being lead around by a leash. Quickly Sierra became the one trying to urge her companion on more quickly in vain, wanting to hurry things along, feeling what seemed like everyone staring at her as she shuffled by, toddling in her diaper, which was feeling more warm by the second.

Her bladder was getting fuller quickly, too, making her squirm in discomfort. She did her best not to let the woman, or anyone else, see her, but as the trip wore on, it became harder to control when she had to do it to avoid peeing herself. Without realizing, it quickly became little more than a toddler's potty dance, adding to her childish appearance, though she still couldn't bring herself to ask the woman to be taken to the bathroom out in the middle of all the other people at the park.

A couple times she spotted her friends, though luckily, mostly they were looking ahead at the long lines in front of them as they waited for their roller coasters. One time, however, one of them turned to look almost right at her, and she froze. She wasn't sure if her friend noticed her or not - she quickly looked away, and Sierra did the same, but Sierra didn't know if that was because her friend assumed it couldn't be her, since she was in a different outfit, if she was going to point her out to the other member of their group waiting with her, or if she just thought Sierra was really a toddler. Sierra also wasn't sure which was worse.

As they reached the end of their round, Sierra's bladder was about to burst, every sign for a bathroom she saw only boosting her need to go. They were getting near the entrance of the water park, where they'd started, so she couldn't help but hope that this torture was nearly over.

"Okay, I was good," she whined, trying once again to get the woman to move faster with a tug on her leash. "Can I change back into my clothes now?"

"Oh heavens no child, it's only been an hour, we still have the whole day ahead of us!" The woman smiled and pulled Sierra towards a bench, "However, it is time for some lunch, so let's that belly filled with some yummy food!"

"We can't do this all day!" Sierra squealed, suddenly feeling very worried. What were they going to do for the rest of the time?! She didn't like the idea of just wandering around the park the whole time, as she was sure that, eventually, her luck would run out and one of her friends would spot and recognize her, if they hadn't already, but she didn't like to think of the other alternatives, either.

She had to admit that she was a bit hungry, though, and the idea of lunch wasn't too bad. She wouldn't have chosen to have it with this woman, but at least they'd probably be sitting still for it, which would limit her exposure, and the table and chair would hopefully hide her diaper.

She didn't expect the woman to push her down onto a bench, however, and pull a large bottle out of her bag. Sierra whimpered as it was thrust into her mouth, filling it with juice right away, leaving her desperately swallowing to keep it from running down her cheeks and making her look like a messy toddler to anyone passing by, since they were in full view. Every drop, however, only filled her bladder fuller, and it was already dangerously full.

"Please," she managed to gulp, pulling her mouth away, sending a few drops of the juice towards her watermelon collar before the woman could shove the bottle back in. Desperately, she tried again, nervously eyeing the still quite full bottle, not sure she could finish it all without an accident. "Please, can we just..." she tried again, uselessly. She began to squirm anxiously, waiting for her next opportunity, managing, slowly, to blurt out, "Can't I finish this in a minute? I need to use the ba-bath-potty!" bit by bit. She blushed as she had to switch to the more juvenile version of the word since she wasn't being given time to say bathroom, only to finish right as the bottle was drained, with her bladder felt so full she wasn't even sure if she could make it to a bathroom in time anymore.

"Already?" the woman shook her head. "We haven't even had any fun yet! Come on, let's just go on one ride, then you can go 'potty'." She grinned down at Sierra, seemingly to ensure that she knew that her choice of words had not gone unnoticed. "But first, finish your lunch."

Sierra groaned as she saw the woman take out a jar of baby food. "I'm not hungry!" she whined desperately.

"All right, all right, cranky-pants," the woman conceded, stashing the jar back in her bag and standing, tugging the leash. "Now, what do you want to ride?"

"Nothing!" Sierra whimpered, pressing a hand to the padding at her crotch. "Please..."

"Nonsense, surely you came here for a reason. If you're going to act like that, I guess I'll just have to pick."

Sierra began to worry as soon as the woman began walking her around again, not sure what she might choose. At first, she was sure it would be a ride with a long line, and that there would be no chance she could make it to the end without an accident, but fortunately, she was wrong, and the woman led her right up to the front of her chosen ride.

Unfortunately, the ride was the Ferris wheel. Immediately, Sierra tried to pull away, but the woman was too strong for her, and before she knew it, she was seated across from her in one of the cars, being lifted up into the air slowly, with no hope of escape until the wheel made it all the way around. Sierra squirmed frantically, her diaper crinkling beneath her loudly, unable to even try to be sneaky about what she was doing - or trying not to do, rather - even as the woman's eyes bore into her.

Finally, their car lurched into place at the rop of the wheel, and Sierra told herself they were halfway there. She still hadn't lost it, so maybe there was a chance. Maybe...

The car lurched forward, then swung back into place, staying at the top of the wheel. It did it again before it stopped moving completely.

"Oh, that's too bad," the woman cooed as Sierra stared out at the park laid out beneath her, hardly able to believe what was happening.  "Well, then, since we have a little time," the woman smiled, reaching back into her back and pulling the jar of baby food and spoon back out. "We might even have time to change you up here, since I'm sure you've soaked your little diaper."

"What?!" Sierra shrieked, hardly able to believe that was what the woman was concerned about right now, opening her mouth up quite conveniently to welcome a heaping spoonful of mashed peas into it. Her nose wrinkled at the taste, and the last thing she wanted to do was eat any more...

As a babysitter, she knew the tricks for getting a fussy baby to eat when it didn't want to, but even so, she couldn't help but fall for them anyway as she tried to explain in between bites of gross mush. "This isn't fair! A-And I have not! I'm not a baby!" She paused only as she realized how loud she had gotten in her anger and desperation, and how much like an actual child she no doubt sounded.

She blushed, looking down and getting a fresh helping of the baby food when she tried to collect herself to start again. To her dismay, she felt a warm spurt of urine flood her warm, sweaty diaper, already slightly damp diaper as she sat there, barely able to stop the flow. If only she had her wand... She probably could have found a time to escape this woman already, and everything would be okay! Then again, she probably would have left it in her bag, so it probably would have wound up in the depths of the woman's own bag.

Strangely, just as she felt the wetness in her diaper expand, the Ferris wheel lurched back to life again. Had it been stuck at all? It seemed to have been there for a while, longer than she would have expected. It had been plenty of time for her to eat nearly a whole jar of baby food, since the woman had just one more spoonful to shove into her mouth as the wheel began to take them back down to the bottom, where the woman tugged her out of the car. "Now what was it you wanted to do after that?" the woman asked teasingly. "Oh, right! Let's see..."

Sierra blushed as the woman lifted her skirt and pushed a hand into her leggings, pushing against the damp padding inside with a grin. "Oh, I see you're getting more into the role of things now! But I think that just proves you're still not big enough for the 'potty'..."

Sierra felt quite full now, which only added to her discomfort. When the woman pulled a pacifier out of her bag and shoved it into Sierra's mouth to stop her whining, without even thinking about it, Sierra began to suck on it, finding it all too easy to revert to that habit in this stressful situation.

"Well, then, let's go on another ride!" the woman declared, yanking Sierra along to the end of a relatively short line, though one that led to a roller coaster. Sierra blushed as she saw the line the woman was taking her towards, sure that there was no way she'd be able to keep her diaper dry through a coaster. Even worse, she was certain this was one she'd heard her friends mention wanting to go on. Would one of them be there, or had they already hit this one? In fact, what if they'd already ridden all they wanted at the main park, and were now at the water park looking for her?

None of it mattered much at the moment, it turned out, as the woman took her over to the board with its humiliating, "You must be this tall to ride" emblazoned on it. Sierra knew right away she wouldn't meet the requirements, making her glad she hadn't been with her friends when they rode it... Even so, while she didn't want to ride it with this woman and a full bladder, either, she had never wanted to be taller more than she did then, knowing how much higher than the top of her head it would be.

Sure enough, she didn't come close, and the woman was all too happy to point that out after pushing Sierra underneath it.  "Aww, looks like you're not tall enough for this ride sweetie," the woman said, "I guess we'll have to find you a smaller ride to go on."

Sierra squirmed, sucking harder on her pacifier instinctively as the woman loudly pointed out that she was just too small for the ride. She could hear a group of younger teens waiting in line snicker, and she quickly looked away, blushing, only to realize that one looked awfully familiar. She felt another rush of pee escape into her diaper, making the padding a little warmer and squishier around her crotch, amplifying her humiliation as she realized the girl was someone she had babysat, though not for years. She hoped the girl didn't recognize her, was sure she couldn't, but as the woman pulled her away, she saw the girl walk up to the height stand, showing off just how easily she surpassed the requirement, and Sierra felt certain that the girl did know after all.

Thankfully, the woman seemed to be done there as she began leading Sierra back through the park, this time over to the swing ride, zooming high overhead. "I think the swings will do just nicely, don't you agree?" she asked, getting into line without waiting for an answer.

Sierra stared up at the swings as they stopped again, her stomach feeling a little queasy as she saw how high they went. She'd never been a big fan of heights, either, which likely contributed to why she didn't like roller coasters so much. She shook her head, then, embarrassed that she hadn't thought of it before, reached up to take out the pacifier.

"I don't wanna ride anything, I want to go to the bathroom," she pouted. Unfortunately, it was right then that she noticed her diaper growing warmer, the padding expanding a bit. Her cheeks turned bright red as she realized she was wetting herself, much more than just the little accidents she'd been having, and, without thinking, she reached down with her other hand, trying to press it to her thickly diapered crotch, but there was no stopping it now, leaving her unable to do anything more than whimper and fidget as she peed her pants like a little baby.

The woman took the pacifier from her hand and pushed it back between her quivering lips, then reached down to lift the dress and pull back the leggings. "Hmm, well, looks like you certainly did that, but you should be fine for a little while longer." Sierra was too stunned at first to try to push the dress back down, and by the time she started to, the woman was letting the leggings snap back into place, giving the front of the diaper a hard pat, then moving the two of them closer to the ride.

"No!" Sierra whined as she was pulled along toward the front of the line, mumbling around her pacifier. "Come on, don't leave me like this!" She squirmed, diaper squishing between her legs as she walked. "Please, just ch..."

She stopped as she realized that they were already ready to go on the ride, the much smaller line for that ride having already come to them. She didn't want to have to be in the diaper any longer than she had to, especially not while sitting on this ride, way up in the air! "Come on..." she hissed, moving closer to the woman, trying to keep her from taking her to the seats. "I just want a change..." Sierra pouted as she was lifted into the seat and locked in place, squirming as her bottom sank into the sodden padding of her diaper. She supposed she was lucky that it was so thick now, since she had really had to go... She didn't think she'd have to worry about it leaking, at least for now. If the woman made her stay in it for long enough to go again, though, she wasn't so sure...

It was only after a few moments of worrying about that when she realized that the woman had left, and not just to a different seat, but off to the side, camera out and pointing at her. She wasn't even riding the stupid thing herself! Quickly, she began to reach for the restraints holding her in place, thinking that maybe she would be able to get out and make a run for it, but it was too late.

She groaned as the seat began to rise, pulling the diaper even closer to her skin. It was hard to be too bothered by the height of the swings as she was distracted by that sensation, at least until they began to really pick up speed. Between that and her wet pants, it was hard to concentrate, but she thought that maybe she'd be able to take advantage of the woman leaving her alone, that perhaps she could get herself free and get away. Of course, she didn't dare try to undo the ride's restraints while it was spinning, but she could try once it slowed down...

Though, honestly, with as nervous as she was, she couldn't get up the courage until she was almost all the way back on the ground, and only then when she saw some of the other kids doing the same, when they didn't even have a crazy person to escape from. Anxiously, she began to fumble with it, not sure what she was going to do if she did get away, with no money, cell phone, ID, or other clothes, but surely figuring something out would be better than subjecting herself to spending the rest of the day with this woman. Her fingers slid clumsily over the lock, but for some reason, it refused to do anything. Was it automatically set not to release until the ride was stopped all the way? It didn't look that advanced, but maybe she was wrong.

All too soon, Sierra felt her feet hit the ground again, and she was nowhere near out of the restraints. Cursing under her breath, she tried harder, but it was already too late, and a moment later, the woman's hand reached out from behind her, pushing her own away. "Here, let me help you out." she said woman, releasing Sierra from her restraints, "Little babies shouldn't be messing with stuff like this, they could get hurt." Refastening the leash to her harness, the woman pulled Sierra out of the ride and continued on into the park. "So, how did you enjoy the ride?"

"I-It was fine," she pouted as she was led away from the ride. "But can I please change now?"

"I'll change you when you've used that diaper to it's fullest, I only brought so many diapers with me and it'd be a waste to change you every time you wet yourself."

Sierra had just enough time to worry about just what "to the fullest" might mean before she lost the ability to ask, eyes widening as the woman pulled out another pacifier from her bag. She took the old one from Sierra's mouth, then popped the new one in. This one's bulb was quite a bit larger, but, more worryingly, it was no normal pacifier, but a gag, and the woman strapped it behind her head and locked it into place. "There, now I won't hear anymore whining out of my little babygirl."

Sierra blushed, shaking her head at this new indignity, and at the woman called her her baby girl, starting to really worry about where this was going. While it had seemed weird that the woman had clothes and diapers her size - it was embarrassing, but she knew it was possible that they could have been intended for a real toddler and still fit her all right, though it was a bit odd that they fit as well as they did - but this pacifier gag was certainly not meant for children. Annoyed, she reached up, trying to pull the pacifier out, but, as she'd suspected, finding herself unable to do so. Frustrated, she stomped her foot, mumbling some angry words from behind the pacifier as she glared up at the woman, tugging at the pacifier again.

"Oh, naughty baby, don't play with your pacifier!" The woman declared, slapping her hands away and grabbing yet another thing from her bag. Sierra's eyes widened and she tried in vain to pull her hands away as she saw a pair of mittens coming towards them, but the woman was bigger, faster, and stronger than her, which made her feel almost as helpless as the mittens themselves did. Once the pink, smooth, soft yet thick things were on, forcing her hands into a tight fist, she realized just how much they limited her movement, and it dawned on her how stuck she now was. Even if she could get away from the woman, there was no way she could get the diaper off herself with the mittens on! And with the pacifier, she couldn't exactly explain what had happened to anyone.

"There, now that'll keep your hands nice and secure!" The mittens were soft yet thick, forcing Sierra's hands in to a tight fist. The pink, smooth mittens restricted any movement her fingers might make. "Come here Babygirl, time for another feeding, then I think the cranky baby needs to go home and get some sleep."

Sierra moaned at the thought of another feeding, still feeling quite full from the last one, waiting for the woman to take her pacifier out before blurting, "Please, no! I'm fine!" If she had any more to drink, it would only make it all the more inevitable that she would wet again, and she still had her doubts about how well the diaper would hold up to that... Even if it didn't leak, it would be quite full, and even wetter and squishier against her, making it all the more humiliating. "Please, leave me alone... There has to be some stuff you want to do here! Haven't you had enough fun with me? I'm sure my stuff is dry by now! Can't you just let me go now?"

"Don't talk back to me!" The woman said, "Clearly you are in no condition to take of yourself. I mean you can't even hold it in and soaked your diaper. You're just a little baby and you need someone to take care of you."

"But you..." Sierra tried to protest, only to, once again, be interrupted by a large bottle of juice, stomping her foot helplessly as she was forced to drain it. If anything, it seemed even bigger than the last bottle, though she had a feeling that was just her imagination, and the fact that she felt even more powerless, something that was emphasized as her bladder began to dribble into her diaper during the last few gulps. It also had a strange, somewhat worrying aftertaste to it that seemed slightly familiar, though she couldn't quite place it.

"You're the one who told me to use my diaper!" she fumed as the empty bottle was finally taken out of her mouth, stomping her foot again, not thinking about how loudly she had declared that. "It isn't my fault! I can take care of myself just fine! This isn't my fault!"

Suddenly the woman grabbed Sierra and hastily pulled her over her lap, getting a loud yelp from Sierra as she said, "You are being a very cranky girl!", striking her rear end with great force.

Sierra knew right away that she had gone too far, and she was going to regret it. "I'm sorry!" she squeaked, but the spanking had already begun, and there was no sign of it stopping anytime soon.

"You are being a big brat, young lady!" the woman berated her as she continued to rain smacks down onto Sierra's backside. "You beg for me to bring you here, and then you act like this! You'd think you really were two years old and not twenty! Well, if you want to act like a brat, I can treat you like one!"

Having already been spanked, and with her diaper now wet, the spanking was even more painful and humiliating, and she was wailing in no time, unable to stop herself despite knowing she would only draw more attention to herself, which the woman was happy to take advantage of by loudly and repeatedly proclaiming how she had earned this, how she was acting so immature and bratty.

Sierra could tell they were drawing a bit of a crowd, but she did her best not to pay attention to them, at least until she happened to catch sight of one person in particular, standing there, grinning - the girl she'd used to babysit! Sierra's cheeks found an even deeper red to turn as she squirmed on the woman's lap, now unable to look away as she stared at the girl's face, partially obscured by her phone, which she was recording a video of the spanking on.

In the midst of all of that, the bottle was starting to catch up with her, and she didn't even realize it because she was too busy with her punishment. It was only when one of the girl's friends pointed and the girl happily moved towards Sierra's backside that she realized she was wetting herself again, and had been for a while. And, worse than that, once she did notice, she realized she couldn't stop it, and that she could feel a little wetness against her legs where the diaper didn't cover. She was leaking.

She, a grown woman, a graduate of Ilvermorny, as far as anyone was concerned, was not only in diapers, had not only been spanked, and wet herself, twice each that day, but she had actually leaked! She wasn't sure how bad it was - it might just be a little wet spot - but it was enough to be embarrassing. She could only hope that her former babysitting charge hadn't recognized her, had just thought it was a funny sight, and didn't circulate the video to her other clients.

"I'm sorry!" she wailed, defeated, just wanting it to end. "I'll be a good girl! Please, stop!"

Feeling the wetness from the diaper leak, the woman quickly stopped and berated Sierra, "Oh my! You are just the biggest baby aren't you?" she spoke loudly, continuing to make sure everyone knew how much of a baby Sierra was.

Sierra wanted to sink into the ground as the woman called her a baby again, hoping that, now that the spanking seemed to be over, her former charge would lose interest and leave her alone. Unfortunately, she realized a moment later that the woman was about to give everyone even more of a show, pushing Sierra off her lap and onto the bench.

As soon as Sierra was laid down on her back, she knew what was coming, although she couldn't believe it at first. Surely the woman wouldn't... Not here! And yet, before she could even stop crying after the spanking, the leggings were off, leaving her sodden diaper completely exposed, and then, before she could fully recover from that embarrassment, even that had been removed, letting anyone passing by see her bare, red, wet bottom. Again, she heard the girl's giggling ring out, reminding her that this was almost definitely being recorded.

"Well, since clearly one diaper isn't enough, we'll have to go with two. And try not to leak again, these are the last two I brought - you promised me I wasn't going to need them today!"

Sierra gasped at the thought of being put into a double diaper - one was bad enough! - but there was no stopping it, and soon the extra thick padding was securely in place between her thighs, forcing them even further apart than before. She felt like she was trapped in the middle of a volleyball or something, and that feeling was only amplified as she was pulled to her feet, after watching the woman toss the leggings into the garbage. She had even more of a waddle now, one that was quite unmistakable. She doubted the leggings would even have gone on over them, if they hadn't been wet. Without them, the dress was just barely long enough to cover the diapers, if she was standing still. Otherwise, she was flashing them to everybody, which she had no doubt would make quite the closing shot for the girl's video.

"Well, since you soaked my clothes, you'll have to pay me back for them. But since you have no money, I guess you're going to have to work them off. You'll be coming home with me tonight, and tomorrow you'll be working off those clothes, they're very expensive you know. Especially those diapers!"

And, just when she thought the worst had to be over, the woman told her that she was going home with her. "No!" she blurted out automatically. "I-I don't have any money, but my friends do! They'll pay you back!" She hadn't wanted her friends to see her like this, but if the alternative was going home with this crazy person, she would just have to live with it. Who knew what she would do to her there?! "We just have to find them!" She groaned as she felt a sudden cramp in her tummy. Really, it had been going since a little while into the spanking, but with everything else, she'd been able to ignore it fairly well, but it was starting to get bad. She had felt full after the baby food, but this was definitely something different. "A-And a bathroom," she added hopefully.

"...Fine, take me to your friends," the woman said, much to Sierra's surprise.

"Yeah, but..." Sierra started to protest, annoyed that the second, and more urgent, part of her request had been ignored, but the woman's re-insertion of the pacifier gag keeping her from asking for the bathroom again, even as she felt an even worse cramp, signalling that her need was growing even more urgent than before.

Well, she'd just have to find her friends quickly, then. While she couldn't imagine the woman would really want her to do... that... in her diaper, she wasn't sure now, without being able to use her voice, how she would convince her to take her to the bathroom. So she began to toddler her way through the park yet again.

With her double thick diaper, her pace was even slower than the woman's had been earlier, and her undergarments were now even more obvious. They were also even more hot and uncomfortable, making her feel like she was stuck in a sauna. The cramps, which were increasing in size and number, did nothing to make her feel any more at ease with her situation.

A couple times, she had to stop, pretending to look around for her friends, so she could contain one of them, and, as her search wore on, that became less effective, until finally, her eyes widened as she felt something warm and mushy begin to push its way into the rear of her thick, tight diaper. She managed to stop it, grunting frantically behind her pacifier, but it was obviously only a temporary measure, and, humiliatingly, she could feel the little bit that had escaped squishing against her bottom.

The little mess began to grow, too, as the cramps continued, getting even worse. It was growing hard to concentrate on anything else now, her pace slowing even more, but, luckily, the search finally paid off, as she spotted a pair of her friends waiting in a line not too far from them.

She turned to the woman, tugging on the leash to try to get her attention, and starting to point them out, only to freeze as, to her horror, the last bit of her control slipped away and she began messing her diaper in earnest. Her friends were nearly at the head of the line, and she knew that she needed to hurry or she would lose them again... But at the same time, the thought of them seeing her dressed like this was bad enough. She couldn't bear the thought of them seeing her filling her diaper, which her body seemed quite content on doing, despite her best effort to stop it. But if she lost them now, would she be able to find them again, or would the woman finally just assume she'd been lying about her friends and give up on the search? She wasn't sure what to do, so she just stood there, eyes wide, as she continued to poop, unconsciously sucking on her pacifier.

"Are you filling your diapers?" the woman asked.

Sierra blushed at the question, fidgeting in place as she felt her diaper continuing to fill, the mess pushing out into the small space between her skin and the diaper, then expanding it outward. She squirmed even harder as the woman pressed her hand to the rear of her diaper, mushing the still growing mess against Sierra's bottom as she felt the diaper grow for a moment before declaring, "My, you really are a baby, aren't you?" and giving the still-filling diaper a pat.

That was nothing compared to what came next, though. Sierra let out a gasp and a squeak as the woman turned to look right at where she'd been pointing at her friends, then began to pull her towards them. She tried weakly to pull away, but she couldn't do it earlier - she definitely couldn't now that she was so preoccupied with her infantile activity. Her cheeks turned bright red even before the woman brought her to her friends' attention, and she stared down at her feet, praying that, somehow, they wouldn't recognize her.

"Excuse, you two wouldn't happen to know this girl, would you? Or should I say, baby?" the woman asked.

"Oh, my god," Ashlynn gasped, looking down at her. "Sierra?! What are you wearing?!"

"What are you doing?!" Nora asked, reaching out for Sierra's skirt. Sierra tried to squirm away, cheeks bright red as she failed and her thick diaper was revealed. Nora sniffed, making Sierra's stomach churn. "Is that you?!"

Sierra stood there for a long moment, shaking her head desperately before Ashlynn began to laugh. "Oh, my god... It is! Look! I think she's still doing it!"

Sierra wanted to die, right then and there, as her friends stared at her while she fidgeted anxiously, pooping her pants like the baby she was dressed as, everyone around her knowing just what she was doing, and seeing it. She shook her head again.

"Don't lie!" Nora scolded her. "You obviously are! Just look at you go! You are filling that diaper to the brim, aren't you?"

Weakly, Sierra tried to shake her head again. Her friends always tended to treat her like she was younger, but now her friend's tone had shifted, sounding like it did when she was talking to a real toddler. They babysat together from time to time, so Sierra knew for a fact it wasn't the first time the girl had seen someone messing their diaper in front of her, and she was taking it in stride quite well, almost as if this was just the sort of thing she would expect from Sierra.

"Gross!" Ashlynn wrinkled her nose. "Look, you have your fun however you want, but you're definitely not getting back into my car like that!" Sierra blushed even deeper as the girl reach out and poked the bulging diaper, glad that, at least, her body seemed to be pretty much emptied.

Nora glanced up at the woman finally, having been too busy teasing her friend to remember the question until then. "Yeah, we know this little stinker... Though last time we saw her, she was only in Pull-Ups. Has she been making trouble for you?"

Sierra's eyes widened, and she wasn't sure whether to be mortified that they had known about her little protection during the car ride, or angry at them for just assuming that she was the one making trouble.

"Yeah, she's been a handful all day long, and she even leaked her diaper! Can you believe it?" the woman laughed. "Well, if it's fine with you, this little stinker owes me a new outfit, and with no way to pay for it I think spending some time with me will do just the trick!" the woman said, pinching Sierra's cheek and giving her diaper a good spank.

Sierra's eyes widened as she saw her friends laughing along with this woman, further confirming that they didn't seem to find any of this all that strange, like she belonged like this. So when the woman continued, despite her trying to shake her head - though she was distracted by wrinkling her nose at the squelch of the smack on the seat of her diaper - she knew what was coming. It didn't take all the sting out of it, though, especially when Nora said, "I think that's exactly what she needs."

Did they think she liked this?! Or did they just think this was fitting for her, as immature as she was? She wasn't sure she wanted to know the answer.

She whimpered behind her pacifier as Nora followed the woman's example and patted the bulging seat of her diaper. "Don't change her too soon, though... She always stuck me with changing the messy diapers when we babysat together, even if it happened while I was in the middle of something else, so it'll serve her right to stew in it for a little while."

"Oh did she now? Such a naughty little stinky baby! Well, it is getting late, say goodbye to your friends, baby," the woman said, once again giving her full diaper another smack.

Sierra wrinkled her nose as her diaper was slapped again, any last bit of hope she had that her friends would save her after all draining as they told her goodbye.

"You could have just told us about this instead of setting this whole thing up," Nora told her. "It's not like it's any big surprise."

Sierra's eyes widened a little at that, though, with the pacifier strapped in, there wasn't much she could say to that. How could it not be a surprise? She wasn't a baby!

"It is pretty funny, though," Ashlynn giggled, smacking the diaper again. "Look at this big present she made you, Nora!"

"Oh, no, for once this one isn't for me," Nora shook her head, reaching out and tickling Sierra's tummy, making her laugh again, not having expected that. "But don't worry, sweetie, I don't mind changing you once you're back from this little game, now that we know about your diapies. But we'd better let you go for now... It is getting awfully late, and we know how cranky you get when you don't get enough sleep!" Nora kissed her on the forehead, just like Sierra had seen her do with their babysitting charges. She tried her best to communicate that this was not what she wanted through her eyes, but it didn't work.

"Be a good girl, squishy butt!" Ashlynn told her, giving her diaper one last smack. And with that, they were gone, leaving Sierra alone with the woman as they ran off, laughing to each other while Sierra was yanked in the opposite direction by her leash.

As the woman pulled her back through the park, Sierra's pace was slowed even more from the large mess in her diaper, blushing as she felt it shift and squish with every toddled step through the park. She was pretty sure Nora was wrong, and she didn't leave the poopy diapers for her EVERY time, but it had definitely happened a couple times. Now she felt a little guilty, since she knew all too well how the kids felt, between this and her experiences at school.

"I think we have time for one more ride," the woman announced. "Let's just see if we can find something around here that you're big enough for." The woman paused and pretended to look around, though Sierra wasn't fooled. She had no doubt that the woman had intentionally stopped right where she was before saying that, because the merry go round was right across from them. Sure enough, that was the ride the woman chose. "That looks like fun!" she exclaimed, tugging Sierra over to it, choosing a horse for her and lifting her up onto it, setting her down on her full diaper and then wrapping the leash around the pole above the horse before stepping back and pulling out her camera again.

Siera squirmed and blushed, but at the same time, she realized this might be her best chance to get out of this. She waited until the ride had started up and the horse began moving between her legs, making her wriggle even more in her messy diaper in embarrassment, then reached up with her mittened hands towards the leash. The ride wasn't going that fast... If she freed herself, she could just jump off and, hopefully, run away before the woman had any idea what was happening. She wasn't sure where she would go, or how she would get out of the ridiculous outfit she was in, but she'd find a way.

She had to pull her hands away as the merry go round spun back around to its original position so the woman wouldn't see her, then started again. For some reason, it was even harder to grab at the end of the leash than she'd expected. With the mittens, it obviously wasn't going to be easy, but somehow, she couldn't get it at all. Groaning behind her pacifier, she tried again, and again, to no avail. The leash wouldn't move. She grew more and more frantic, just trying to budge the thing, not even to unfasten it, but it refused to do anything. She didn't even care if the woman saw her anymore, as the ride sped up, the horse bucking more wildly underneath her.

Then it came to a stop, and the woman walked up to her, pushing her hands out of the way and easily unwinding the leash from the pole. "You could have fallen off, you naughty girl! I think you need a real spanking when we get home - bare bottom, with a hairbrush!"

Sierra mumbled desperately behind her pacifier, but it was no good, and the woman began to tug her back through the park, out of the exit, and into the parking lot. "Alright little baby, once we get home I'll feed you a nice big dinner and it's off to bed! I hope you had a fun day at the amusement park because you'll be spending your days in very messy diapers!"

Sierra had hoped that the woman would change her before they left, but instead she was plopped right down on her bottom in the seat, the mass in her diaper squishing even worse than ever, and buckled tightly in, with the promise of even more messy diapers to come.

Sierra squirmed uncomfortably on the way to the woman's house, each bump reminding her anew of her position. While she didn't want another spanking, she would have preferred one of those for doing something so babyish to the prospect of being expected to do it again the next day. One dirty diaper was bad enough, but as a regular thing again, like with Anna? She shuddered at the thought. And the woman had said 'days'... How long did she expect to keep Sierra? It was just some leggings! They couldn't be that expensive. And a diaper - or three now, she supposed - but still, there was no way it could take that long to earn enough money to pay her back for them! Sierra began to suck on her pacifier gag nervously, as she started to seriously worry when, or if, she was going to escape from this crazy woman.

The house the woman took her to was quite large, and rather fancy looking, making Sierra feel all the more certain that it wouldn't have been any problem for her to just pay for a pair of leggings and a few diapers without taking her. "It's just about your bedtime, but first, we'd better get you that spanking!" the woman announced, getting out of her car and walking around to Sierra's door, opening it and pulling the girl out and into the house.

Sierra didn't see or hear anybody else there as she was pushed into the living room, the leash wound around one of the legs of a five tier corner stand displaying photos and a few knickknacks while the woman left to get the promised hairbrush. It was relatively small, and didn't look all that heavy, but for some reason, when Sierra could once again not unwind the leash from where the woman had put it, she also couldn't move the shelves one inch, no matter how hard she tried. It was only after a few moments of struggle that she looked at the things adorning the stand and noticed something quite worrying. Besides what looked like an inactive golden snitch and an ancient looking wand, there were quite a few pictures. There was a girl in nearly all of the pictures, about her age, who looked very familiar.

"Now have you figured it out?" the woman asked from behind her, smiling as Sierra turned around to stare at her with wide eyes. "Olivia was just devastated that you would cheat her in a fair fight like that. She's with her father right now, and he's doing her best to console her, but you know what they say - mommy knows best. And I think what she needs to cheer her up is you, as a perfect, obedient little babygirl sister that she can do with as she pleases. We have a full month before her father drops her off here to get you to that point. I think we can do it, don't you?"

Sierra gulped and began to suck her pacifier nervously, watching the woman tap the brush she was carrying against her palm. She would have liked to think that she could avoid that fate, but after just a week with Anna, who was just younger and less experienced, and stuck with all the rules of Ilvermorny, that had already very nearly happened. Who knew what a month with this woman would do to her? She shook her head desperately, but already, as the woman approached with the hairbrush, she could feel her bladder dribbling nervously into her full diaper, and she couldn't help but wonder if she was already too far gone.
