Sierra knew as soon as she woke up that something was wrong, and her fears were only confirmed when she opened her eyes to find Robin standing over her, arms crossed. Sierra groaned, rolling over and wrinkling her nose at the wet feeling underneath her. Drowsily, she looked down at herself and saw that while she'd been asleep, she'd wound up tossing and turning enough to wiggle out from under her blankets, making her Pull-Ups, now soaked, and the large wet spot under them, completely visible. Her lollipop, half-eaten, was also stuck to the sheets.

"I told you I had to go to the potty!" Sierra whined, immediately trying to head Robin's anger off at the pass.

"And I'd just taken you there five minutes earlier, and you couldn't produce a single drop there," Robin reminded her. "Now look at you! You've wet your bed for the second time today! You even got your shirt wet!" Robin grabbed Sierra, pulling her into a seated position, and yanked her shirt off, leaving her sitting there on her wet bed in her cutesie, heart-covered training bra, and her leaking, Cinderella adorned training pants. "What do you have to say for yourself, young lady?"

Sierra fidgeted on the bed nervously. Obviously, Robin wasn't going to accept her denying Sierra's trip to the bathroom as an excuse, and that was pretty much all she had. She nibbled her bottom lip anxiously, trying to come up with something else, before finally settling on, "I feel sick."

Robin's expression softened slightly. "I was worried about that," she said. "Come on, let's get you cleaned up." Gently, she reached for Sierra's waist, pulling apart the sides before helping the girl to her feet, naked except for her childish training bra. Without the shoes, Sierra was sure she'd be able to walk normally, but Robin still held her hand tightly as they went into the bathroom, and Robin cleaned her bottom half with a damp washcloth.

It was only when they went back out to the bedroom that Sierra noticed what was laid out on Robin's bed and began to try to pull away from the woman's grip, especially when she realized that was where she was being led. There was a pink plastic mat and on top of that was one of the thickest diapers Sierra had ever seen. She remembered Samara saying she had to go get them 'from the back', and had no doubt that the brat had used her magic to expand them to this ridiculous size.

"Please," Sierra whined. "I want my Pull-Ups!"

"You've already used up today's Pull-Up," Robin reminded her, pointing over to her bed, where the used training pants were still lying. Sierra was delighted to see that she could read the 'Monday' printed neatly across the top. The spell from the glasses had worn off! Unfortunately, that didn't take away the diaper that crinkled softly under her bottom as Robin lifted her up onto the bed, pushing her onto her back. Sierra turned her head, not wanting to look at the huge diaper about to be put onto her, and saw another six Pull-Ups on the bed, each with another day of the week written on them.

"I-I only get one Pull-Up a day?" she pouted.

Robin gave her a sharp look as she sprinkled powder on the squirming girl's crotch. "'Only'? An adult wouldn't even need that! I certainly hope you get over whatever is ailing you soon, but if you're sick enough to wet your pants once in a day, it's obvious you'll do it again, so it's just safer to keep you in diapers after that."

Sierra gasped as the diaper was pulled up between her legs, forcing her thighs apart with a rustle. They were bright pink and covered with hearts, stars, bows, and white letter blocks right across the middle, spelling out, 'Baby'. Sierra felt the hair on the back of her neck stand up as Robin fastened one tape, and then the other, giving her no doubt that there was magic in these diapers.

"There!" Robin patted the front of the diaper, helping Sierra sit up. "That's better! Nice and safe! Now, I want you to go to the corner."

Sierra's eyes widened. Was she really being put in time out?! "Why?!" she demanded.

"If you weren't feeling well, you should have let me put you in a diaper before your nap," Robin scolded. "I gave you plenty of chances, and I told you I wouldn't be happy if something like this happened. You should be grateful I'm going easy on you. Now march!" She pointed to one of the room's corners, and after glaring at the woman for a moment, Sierra trudged over.

Sierra sighed, staring at the wall as she squirmed. How long was she going to be stuck here? It wasn't fair! She shifted her weight back and forth, letting out another, louder sigh that she hoped Robin heard. She looked down at her diaper, wondering what Samara had done to it. Curiously, she reached for one of the tapes, but, try as she might, she couldn't get ahold of it. Her hand slid across the slick, plastic cover of the diaper, making it crinkle loudly, but nothing more than that.

"Hey, hands off, young lady," Robin scolded her. "Oh, and you forgot these." Sierra started to turn around, only for Robin to slip the glasses onto her face. "Whether you like them or not, these are both for your own good." She gave Sierra's diaper another pat, then walked across the room. Sierra heard the phone being dialed, and a moment later, Robin said, "Housekeeping? Hello! I'm sorry, but I'm afraid I need more clean sheets..."

Sierra's face burned as she listened to the one-sided conversation, wondering how long she was going to be stuck in time-out. She could just imagine standing there as the sweet old cleaning woman came in to clean up her wet bed again, her nose stuck in the corner and her diaper sticking out behind her very obviously. But even if she was allowed out, what was she going to do? Sierra was pretty sure none of the clothes that had been bought for her that day would come close to covering the entire diaper, and her own suitcase still hadn't shown up!

The cleaning lady had already seen her in a Goodnite, had potentially seen her Pull-Ups, and knew very well about her accident. She'd even caused it, even though Sierra was pretty sure it hadn't been intentional. On one hand, being seen by her now that she was demoted all the way back to diapers would be humiliating, but she doubted it would come as a surprise to the woman.

That didn't keep her heart from pounding as she heard a knock at the door. She fidgeted in her corner, having still not been allowed out, waiting to hear the door close behind Robin and the cleaning woman to at least block the view of her from anyone who happened to be walking past in the hallway.

"All right, Sierra, you can turn around," Robin said. "I want you to apologize for making a mess that this nice lady has to clean up now."

Sierra almost would have rather stayed in time-out! She'd already apologized to the maid once already today! She wiggled in place, trying to will something into existence to cover her training bra, which was flattening her chest, or her diaper, which felt even thicker than ever now with someone else in the room, but nothing happened.

"I'm sorry!" Sierra started, reluctantly shuffling around. She started talking before she even began to move, so the words were already out of her mouth before she realized it wasn't the same woman.

She supposed it made sense. She couldn't work all the time, after all. Instead, it was a girl in her late teens. She towered over Sierra, with long, bright red hair. Her uniform shirt was unbuttoned probably a bit lower than dress code said it should be, and Sierra couldn't help but stare at the girl's chest, blushing as she thought about what her own looked like right now. The maid's tight pants also made it very obvious that she couldn't be wearing anything as childishly padded as even the Goodnites Sierra had started the day in, much less the diaper she was in now.

"And why are you sorry?" Robin urged Sierra on.

"I... I, uh..." Sierra blushed and squirmed. "I wet my bed."

"You certainly did," the maid giggled, looking over at the wet sheets.

"And?" Robin looked at Sierra. Sierra gave her an inquisitive look back. "What else should you apologize for, from before that?" Sierra was still confused, until Robin finally clarified, "Why does she have to clean up after you now?"

"I-I'm sorry, I didn't put on my diaper before my nap," Sierra stared down at her feet.

"And I asked you, didn't I?" Robin shook her head. "A couple times! But that won't happen again, will it?" Sierra shook her head. "And why not?" Robin kept going, seemingly just to rub it in. Sierra glanced back up at her, still a little confused. "Because you'll be wearing your diapers every time you go to bed from now on, won't you?"

They hadn't really discussed that, but Sierra had no doubt what the answer was. "Y-Yes," she sighed.

"I think that sounds like a good idea!" the maid said condescendingly. "I'm sure there's no way a little girl like you could soak through a big diaper like that!" Sierra's face burned as the maid stepped forward towards her, giving her diaper a pat. "And don't you worry about your bed! I can fix it all up!" She bent over, tapping Sierra on the nose and giving Sierra a very good look at her cleavage.

Sierra blushed even deeper, trying to look away, but the maid just giggled and gave Sierra's tummy a tickle before Sierra could even try to squirm away. Sierra was very ticklish, and couldn't help but laugh and squeal as she tried in vain to wriggle away from the girl's fingers. "You are too cute!" the maid declared finally. "I could just eat you up! But I'd better get to work instead!"

She winked at Sierra, then turned back to her bed. Sierra tried to suppress the few residual chuckles that were still in her system from the tickling, but couldn't quite manage it. She watched bashfully as the maid stripped her bed, turning around and raising an eyebrow at the stuck on lollipop, which only made Sierra blush more. Once she was done, she took another plastic sheet and spread it out over the mattress, then gathered up a fresh batch of bedding.

Robin stopped her before she could do anything more. "You can just leave those on my bed," she said. "We'll take care of the rest."

"Are you sure?" the maid asked. "I don't mind!"

"No, it's okay," Robin nodded. "Thank you very much."

"No problem!" the maid assured her. "Just let me know if you two need anything! And if you want to get out and do anything at night, my shift ends at 8, and I love babysitting," she smiled over at Sierra, then surprised her with another quick round of tummy tickles. Sierra gasped, a trickle of wetness making its way into her diaper before the tickling ended. To Sierra's horror, once it started, Sierra found herself giggling even harder, having a harder time resisting the tickling, which made her go even more, until luckily the maid stopped. "Okay, bye! Have a great rest of your day!"

"All right," Robin said, turning to Sierra as the maid left. "Up on your bed, young lady."

Sierra's cheeks reddened as she looked down at the floor, noticing that the first block on her diaper, the one she knew contained the first B in Baby, although she could no longer read it, was yellow instead of white. It hadn't been that way before, had it? She tried to think, but her mind felt strangely foggy. "It's only because of the tickling!" she said defensively. She realized her mistake as Robin narrowed her eyes, then slipped a finger into the legband of Sierra's now damp diaper.

"Already?" Robin shook her head disappointedly.

"I'm ticklish," Sierra sulked.

Robin, tired of waiting, lifted Sierra up onto the bed herself. Sierra squirmed as the plastic sheet crinkled under her, wondering what this was about if Robin hadn't known about her accident. "Or are you sick?" Robin asked. "Isn't that why all this is happening?"

"Y-Yes," Sierra nodded, nibbling nervously on her bottom lip. She felt her thumb moving up towards her mouth, and as much as she didn't want to suck her thumb in front of Robin, the desire for the soothing feeling she knew would come from it was starting to grow too strong. She wasn't sure she liked where Robin's plans were going. Robin easily untaped Sierra's diaper, making Sierra's own struggle with the tape seem silly with how easily she was able to do it. Thankfully, once the diaper was open, Sierra was instantly able to suppress her need to suck her thumb, pushing her hand back onto the bed. The strange fog that had been rising up in her mind also instantly vanished. Robin unfolded the front of the diaper, leaving Sierra lying there, naked except for her childish bra, as she turned, reaching into one of the bags she'd bought earlier that day.

When she turned back around, she was pulling a pair of latex gloves onto her hands. Sierra's eyes widened at the sight, as she remembered that this version of Robin was supposed to be a nurse. "This is a very strange illness you seem to have, young lady," Robin said sternly. "I think it's about time we get to the bottom of it. Flip over."

"Why?" Sierra whined, but she had a bad feeling she already knew.

Sure enough, Robin lifted the thermometer. "We're going to take your temperature again," she said. "This morning it seemed normal, but you've had plenty more accidents since then, so let's see if you've gotten worse."

Sierra pouted, wanting to yell 'No!', but knowing that she couldn't. Instead, she impotently pounded her fists into the crinkling mattress below her until Robin finally grabbed her, turning the girl over herself and exposing her bottom. Robin held the squirming Sierra in place easily with one hand as the other dipped the thermometer in Vaseline, and pressed it firmly into Sierra's backside.

Sierra had just been through this that morning, but the thick, wet diaper under her now just made it feel worse, especially when she knew what Robin was going to find. Sure enough, after a few minutes of uncomfortable wiggling, Robin extracted the thermometer, then looked at it and shook her head. "Exactly the same. I guess we'll have to look a little deeper, won't we?"

"Huh?" Sierra furrowed her brow as Robin rolled her over again. She gasped as the woman pushed on her stomach firmly, her glove-clad fingertips moving around as if searching for something. "Wh-What are you doing?" Sierra demanded, wriggling as Robin's fingers made their way up her body. Robin stopped at Sierra's chest, and the girl almost thought that was that, but Robin only waited a moment before slipping Sierra's bra off. "H-Hey!"

Robin ignored the protest and began to examine Sierra's breasts thoroughly. There was nothing sexual about it, just business, but that didn't make it any less humiliating as Sierra laid there being poked and prodded. When Robin was finally done with that, she started moving her hands downwards again, back down to Sierra's tummy, and then lower, and lower...

Sierra let out a sigh of relief as Robin moved her hands away from her, turning away for a few seconds. It didn't last long, as the woman turned back around with something else from her bags. It was metal, and very odd looking. Sierra immediately didn't like it, even before Robin advanced on her, moving the item down between Sierra's legs.

"Get away!" Sierra squeaked as she realized where it was going. She tried to crawl away, but Robin held her in place.

"Now, now, we need to be thorough," Robin told her. "We're just lucky they had a speculum at that store. I really didn't expect to find out, but your friend was a big help!" Sierra gasped, feeling the cold metal being gently slid into her, and then opened, making room for Robin's invasive fingers.

That part of the exam felt like it went on forever, stretching on and on as Sierra wished she could disappear. And, when Robin was done with that and finally pulled out the speculum, she still wasn't done! She turned Sierra over yet again, and began prodding at her back, her fingers probing into Sierra's bottom as well. By the time she was done, Sierra was sure the woman had touched every square inch of her.

"Well, then," Robin said, making Sierra sit up on her open diaper, then pulling off her gloves, balling them up together and throwing them out. "You are one of the healthiest girls I've seen in a long time. As far as I can tell, you aren't sick in the slightest. So, why are you really peeing your pants like a toddler? Are you just being lazy? Are you just trying to push my buttons? Or were you just never properly trained in the first place?"

"I... I..." Sierra squirmed on her damp, and now quite clammy, diaper, realizing she was caught in her lie. What was the 'best' answer here? What would make Robin the least upset?

"Are you doing this on purpose, or can you really not help yourself? Or do you really expect me to believe you're sick?"

Sierra fidgeted. Robin was talking big, but she couldn't really know this wasn't because of some illness, could she? She didn't know much about medicine, but surely there was more to it than that! "I am," she pouted.

"Well, in that case, I have one more thing to try," Robin replied. "But I don't think you're going to like it." She reached down into the shopping bag and pulled out a large, red rubber bag with a length of white hose coming out of one end. "Maybe if we flush your system, we can get all the bad stuff out, and that will miraculously make you continent again."

Sierra could tell that Robin didn't think that was going to work, but she could also tell that she'd walked into this by insisting on sticking with her 'sick' story. She gulped as she stared at the enema bag, wondering if Samara had suggested that as well, or if Robin had come up with it on her own.

"Come on, let's go fill it up," Robin said, grabbing Sierra's hand and pulling her off the bed and into the bathroom. She handed Sierra the enema bag and pointed her towards the sink. "Go on, make sure it's nice and full!" she urged.

"Please," Sierra pouted, staring up at the woman with big eyes. "I'm sorry! I feel better now, I swear!"

"Then I'm sure this will complete your recovery," Robin told her, pushing her over to the sink, then reaching past her to turn the knobs, making sure the water was just the right temperature. "Just hold it under the faucet."

Sierra stomped her foot. "I'm better!" she insisted again, throwing the bag on the floor. "Enemas are dumb!"

Robin snatched the enema bag up off the floor, then pushed it into Sierra's hands, making her hold it again before pushing it under the running water and holding it there. Sierra growled and grimaced and stomped her feet some more, but all she could really do was stand there and stare at herself in the mirror, naked, as she felt the enema bag getting heavier and heavier in her hands, knowing that every drop of it was about to end up inside of her. To make matters worse, the sound of the running made her bladder fill as well, making her feel even more uncomfortable with her situation. If Robin wasn't holding her tightly in place, she would have thrown a full-blown tantrum, but that was impossible at the moment.

Finally, once the bag looked as full as it could get, Robin turned the faucet off, taking the enema bag from Sierra and screwing the top back into place. She lifted the bag up, hanging it from the shower curtain rod with its hook and leaving the hose dangling underneath menacingly. Sierra's stomach twisted inside of her as she realized with horror that this really was about to happen.

"I'm sorry!" she tried again, lower lip quivering as she watched Robin grab a tub of Vaseline and dip the enema nozzle inside. "Please, I'll be good!"

But Robin just grabbed her by the shoulders and turned her around. Sierra squirmed and squealed as she felt another invasion into her bottom, this one less cold, but much longer, than the thermometer. Robin gently guided it deeper and deeper into Sierra's insides, then reached upwards and undid the clamp on the hose.

Instantly, Sierra's eyes widened as the water began to pour into her. She gasped and fidgeted in discomfort, shocked at how quickly the bag was emptying, and her tummy was filling. "Please, that's enough," she whined, staring up at the hanging bag, her frown growing as she saw how full it still looked. How much more could she take?! She reached for the hose, wanting to rip it out of herself, but Robin smacked her hand away.

"Don't you dare touch that, young lady, and make another mess in here! You've done quite enough of that already!" she lectured. Sierra pouted, but reminded herself that her wand was on its way. If she just made it through all of this, she'd be able to get that, and she could make everything okay!

She was so preoccupied with the enema that she hardly even noticed Robin leaving the room until she returned, a diaper in each hand. One was the diaper she'd been wearing before her exam, and the other was a fresh one. That hand also held something Sierra recognized, worryingly, as a good-sized butt plug.

Sierra whimpered, wiggling unhappily as the woman approached. "The toilet is right there," she pouted, looking over at it. "Can I just use that?"

"If you can hold it that long," Robin told her. "To really be effective, you have to retain the enema for quite awhile, and you have some things to take care of in the other room. I would just let you wear one diaper, because I think it would be enough, but since you've already used this one a little, it won't be quite as absorbent." She set the plug, and clean diaper, on the bathroom counter, then laid out the damp one on the closed toilet lid before turning her attention to the enema bag. "How are we doing?" she asked, giving the bag a slight squeeze.

Sierra squealed as the water gushed into her with even more force. Already, her tummy was starting to cramp, and she knew she wouldn't be able to hold it for long. She felt so full and bloated! "I have enough already," she gasped.

"You're almost done," Robin told her, patting her condescendingly on the head. Sierra glared at her, squirming desperately under the woman's gaze as the bag's contents emptied themselves into her, feeling like it was going far too fast and way too slow at the same time.

At last, the flow dwindled to a trickle, and, after another experimental squeeze, Robin pushed the clamp back closed and slid the nozzle out of Sierra's backside, quickly escorting the girl over to the toilet, pushing her down onto the diaper waiting on it. Sierra supposed it was the most convenient place, but it still felt like adding insult to injury being right on the toilet, yet knowing she wasn't going to be able to use it.

"Now," Robin knelt down in front of the red-faced, still squirmy girl and looking her in the eyes, "you need to hold this for at least thirty minutes for it to work correctly. Do you think you can do that, or do you need some help?"

"Thirty?!" Sierra's eyes darted over towards the plug, knowing what the 'help' was going to be. She didn't want that, but at the same time, she already felt like she wanted to go. She pouted, staring up at Robin pitifully, hoping for a little mercy, but she didn't see any in the woman's expression. "I can hold it," she sighed. She didn't feel particularly confident about that at all, but what could Robin do about it if she went early? She glanced over at the enema bag still hanging above the tub, hoping that she wouldn't have to go through a second round if she failed. If that was going to be the case, she almost wanted to just use the plug, but she'd already spoken, and she wasn't going to back down now.

Even if she wanted to, Robin was already pulling the diaper up between her legs, pressing the now cold, clammy wet spot against Sierra's skin and taping it into place. As soon as the last tape was in place, Sierra could feel the fog appear in her mind again, and instantly she wanted to pop her thumb into her mouth. She frowned, fidgeting as she fought to stop herself, trying to figure out what was going on. It had to be the diapers, didn't it? But she hadn't felt like this when she'd first had them on, had she?

"Sierra!" Sierra jumped as Robin said her name loudly, making the girl warm the cold, wet spot in her diaper with a trickle of urine that turned into a much larger stream before she could stop it. Sierra couldn't help but giggle a little as she squirmed in her now even squishier diaper. "Sierra!" Robin snapped again. "Are you ignoring me?"

"No," Sierra tried to shake her head, looking up at the woman with wide eyes, which grew even wider as she realized the spell had made her do the opposite of what she'd wanted. She knew better than to try to say no! What was wrong with her?! Even though Sierra was sure the woman was still the same height, she seemed taller now, more intimidating.

"Then pay attention," Robin said coldly, giving Sierra a harsh glare. "Hop off the toilet, please," Robin asked, in a tone that made it obvious this wasn't the first, or probably even the second, time she'd asked Sierra to do it in the last few minutes.

Sierra obediently did as she was told, turning to smile up at Robin, expecting praise for being a good girl. Instead, Robin took the other diaper and opened it up, laying it out on the toilet seat. "Back up!" she patted the thick padding.

"B-But I-I-I..." Sierra sniffled, knowing she couldn't say that she didn't need two diapers, but having difficulty thinking of how else to phrase it. She was a little shocked to feel tears welling up so easily in her eyes at her frustration. She'd used to be a crybaby, but she hadn't been for a while, had she? It was even harder to think now, somehow. She pouted, wiping her eyes and looking down at her feet, hardly even noticing that now the first two blocks on the front of her diaper were lit up. It took her a moment to remember that those first two were a 'B' and an 'A'. She blamed the spell on the glasses, though she wasn't so sure.

Robin picked her up, plopping her down on the second diaper. Sierra pouted, crossing her arms over her chest, but that didn't stop the woman from carefully ripping some holes in the first diaper's plastic, then pulling the padding up between the girl's legs and taping it into place. Sierra gasped as she tried to push her thighs together, only to find that it was impossible. Without thinking, she pressed a hand to her crotch, eyes wide at the feel of the massive bulk there.

"All right, now, you need to go make your bed, young lady," Robin informed Sierra, pulling her hand away from her double diaper and helping her down off of the toilet. Sierra's legs were forced apart into an awkward, babyish waddle.

Sierra sulked and sniffled, not wanting to have to make her bed, which was an awful, boring chore, but too scared of Robin to try to say no, even if she could. "O-Okay," she gave in, slowly making her way out of the bathroom and towards her bed. She stopped as she saw the pile of sheets and blankets waiting for her on Robin's bed, a pout forming on her face at the thought of how much work this was going to be. She whimpered, stomping her foot in protest, then stared up at Robin, hoping for some sympathy.

"Get to work," Robin said, pointing. Sierra stomped her foot again, then scurried over to the bed as Robin's eyes narrowed at her. She grabbed for the fitted sheet, only to clumsily drop it onto the floor. She bent down without thinking to pick it back up, only to groan and clamp her hands over her bottom as the motion caused a worrisome cramp in her tummy.

"You didn't go already, did you?" Robin asked, at Sierra's side in a moment.

Without thinking, Sierra yelped, "No!", which, of course, the spell changed to an equally emphatic, "Yes!" She blushed as Robin pulled out the rear of her diapers, tears starting to sting her eyes yet again at the babyish diaper check.

"You definitely wet again, but it looks like that's it," Robin told her. "Are you sure you don't want the plug?"

"I-I can hold it," Sierra insisted, though she felt much less confident.

"Okay," Robin replied, sounding doubtful as well. Before she could say anything else, Sierra heard a tune playing from Robin's dresser. Robin hurried over to it and opened the drawer, pulling out her cell phone. "I'm going to take this on the balcony," she told Sierra. "But I can still see you, so keep working."

As Robin turned her back to head onto the balcony, Sierra stuck her tongue out at her, then squeaked and turned back to her bed as the woman stepped outside and turned around to face her. Sierra bit her bottom lip as she stared at the sheets again, trying to figure out how to pick them up without repeating her last mistake. After all, her tummy was already starting to hurt even without that help!

It took her longer than she would have liked to admit to figure out how to squat down to snatch up the sheet without putting too much pressure on her full belly. She tossed it up onto her bed, then pulled one corner down over a corner of the mattress and rushed over to the next corner to put it on, pouting and stomping her foot as the first corner popped back off. This was always the hardest part!

She ran around her bed several times, trying to make all four corners stay. She was on the last one, and feeling proud of herself, when she saw the opposite corner starting to pop off. With an annoyed, and frantic, yelp, she threw herself over the bed, reaching for the sheet. Before she could grab it, her tummy hit the mattress, however, and her eyes widened as she felt it push, sending a rush of water, and something more, into her diaper. She gasped, scrambling back to her feet as quickly as she could, fighting all the while to keep control, as she felt the rest of the enema straining to follow suit.

She whimpered, pressing her hands to the back of her diaper and feeling a definite mushy spot there, small, but no less humiliating. She sniffled, looking down at her feet and noticing that the third baby block, the second 'B', she remembered after a long moment, was flashing slowly between white and yellow. She wasn't sure what it meant, but it still scared her.

Unfortunately, in her scramble, she'd undone all of her hard work, so she had to start all over again. It was worse now, her nose wrinkling with every waddling step as she felt her little accident, reminding her of what she'd done, and was getting very close to doing more of. If she'd thought she had a chance of reaching the bathroom before Robin could stop her, or getting her diaper off once she was in there, she would have tried to use the toilet, but she knew it was no good.

She groaned as she went back to work, the cramps only getting worse now that she'd released a little of the enema. She managed to get the fitted sheet on, finally, though, then clumsily put on the regular sheet and blankets. It didn't look as nice as it did when the maids did it, but she still felt pretty proud of it as she stood back and surveyed her work.

Her feelings of pride quickly drained away as Robin stepped back in, handing her the cell phone. Sierra took it automatically, holding it to her ear. "Hello?"

"What exactly is going on there, young lady?"

Sierra gulped as she heard her father's voice on the line. "H-Hi, Daddy," she stammered.

"Hello," he said stiffly before repeating, "What is going on? I thought we were over your little problems."

"I-I am!" Sierra insisted.

"Then why are you having all of these accidents?" he asked. "And why are you acting like a bratty child? I sent you on this trip to bond with your future step-mother as equals, but it sounds like you've been acting like a baby the whole time!"

"I'm a big girl!" Sierra insisted with an offended sniffle.

"Then why aren't you acting like it?" he asked.

Sierra pouted, squirming and groaning as another cramp hit her. "I-I am!" she whined, turning slightly away from Robin. "She's lying, and being a meanie!"

"It sounds like she's giving you every opportunity to prove yourself," her father countered. "I can't blame her at all for the way she's treating you. In fact, I've given her full permission to discipline you as she sees fit. And that includes spankings, young lady, like the one you have waiting for you at home!"

Sierra burst into tears, quivering at the thought. She felt her bladder loosen, pouring into the already wet padding before she could stop it. The third block on her diaper, the one with a funny, swirly shape that she somehow knew should be familiar, but couldn't remember at all now, turned fully yellow as she stood there, whimpering pitifully into the phone. "I'm sowwy, Daddy!" she lisped, "I'ww be good!"

"If you are, then she won't have to do it," her Daddy told her gently. "But she's in charge now, and she knows what's best. You understand?"

Sierra turned and looked at Robin, not even realizing her thumb was in her mouth until she started chewing on it nervously. Robin looked even bigger and more mature now, even though Sierra was sure she hadn't gotten any smaller herself. "Yeth, Daddy," she sniffled around her thumb.

"Good girl," he praised her. She giggled softly, feeling proud of herself, for a moment. He kept talking, but she was distracted by another cramp from her tummy. She knew how to handle this, so she froze in place, concentrating as hard as she could to keep her diaper relatively clean. She knew she could do it!

Except, she couldn't. It was just too much. Part of her knew she'd weathered worse cramps, but that part of her felt very distant, lost somewhere in the thick fog that had settled over her thoughts. She whimpered as her body gave in, pushing a huge mass into her diaper in one awful, humiliating rush. Almost as quickly as that happened, the final baby block on her diaper turned yellow.

She lost her balance, falling flat onto her bulging bottom. The icky mess in her diaper squished all around her bottom, only getting worse and more yucky as she squirmed. Some far-off part of her mind knew she should be able to stand to at least get away from the worst of the feeling, but she was too upset to even try to do that. Instead, she began to bawl. This wasn't just the sniffling and soft tears from before, but a full fledged crying session.

"What's wrong?" she heard her Daddy ask.

"Ah-buh-buh!" she babbled, feeling her diaper grow warmer and wetter beneath her, with no idea what was going on, or how she could stop it, if that was even possible. "Gah-gah-buh!"

Robin bent down, plucking the phone away from the sobbing girl. "The enema I gave her just hit, and I don't think she was ready for it. I didn't expect her to get so upset! I'd better get her changed and see if that makes her feel better. I'll talk to you later. Love you, too!"

Robin set her phone on her bed, then knelt back down in front of Sierra. "Shh, it's okay," she tried to soothe the girl. "It's just a messy diaper!" That didn't stop the girl from crying, however, and when Robin tried to take her hand to help her up, she couldn't make more than one clumsy attempt to stand before falling back on her full diaper, which started her crying even harder. Finally, Robin just laid the changing pad out on the floor next to her and slid her over onto it.

As soon as Robin untaped the diapers, Sierra let out a gasp mid-wail, her cheeks darkening at how she'd been behaving, and at the very full diaper Robin was in the process of cleaning up. "That really was quite the big mess, wasn't it?" Robin cooed. "You've been holding it, haven't you? That isn't good for you. I think we'd better keep an eye on that, too."

Sierra's blush grew even darker as she tried to get herself back under control. The fog was gone from her mind, and that only made the way she'd been acting even more humiliating, especially as she tried to force the last of her tears to dry up. "I-I can clean myself up," she offered quietly.

"I can't trust you to clean yourself properly after using the toilet," Robin said, gently but firmly. "I don't think I can trust you to clean up after this."

Sierra squirmed, letting the woman finish the job silently. When Robin turned and grabbed a fresh diaper, however, Sierra whined, "Please, can I have a Pull-Up at least?"

"No, Sierra," Robin told her. "We've already promised, twice, that you weren't going to leak on your bed again. This time, we're going to make sure."

Sierra gulped, eyes firmly fixed on the baby blocks on the front of her diaper as soon as the padding was tugged up between her legs as Robin taped the diaper on, up until Robin pulled her into a sitting position and slid a pair of pajamas shorts up her legs. They were ridiculous, pink and so short the waistband of the diaper stuck out the top and bits of the diaper were visible through the legholes. The top was hardly better. It was pink as well, with a ruffle on the bottom that stopped just short enough that her diaper's waistband was still visible.

She vaguely remembered trying it on at the store, though there had been so many outfits it was hard to keep them all straight. With the training pants, you could almost hide the fact that she had some protection on underneath, but with these diapers, there was no chance. She didn't realize how obvious it really was until Robin led her back to the bathroom and she saw herself in the mirror. She might as well not even be wearing the shorts! Anyone would know, instantly, what she was wearing underneath!

Robin stepped behind her, gently taking Sierra's hand and guiding it over to the toothbrush. "I can do it myself," Sierra protested, but Robin wasn't taking any chances. She obviously didn't trust Sierra to do anything by herself anymore. She squeezed the toothpaste onto the brush herself, then guided Sierra's hand up to her mouth and began to brush her teeth, turning on the faucet with the other hand to prepare for when the brush needed to be rinsed.

Unfortunately, the running water also began filling Sierra's bladder up yet again. She tried to rush through her task, but Robin just kept telling her to slow down and take her time, with the water's sound pounding in her ears the whole time, ensuring there was no way she was going to wake up the next morning with a dry diaper.

When Robin was finally satisfied, she let Sierra go, but the girl couldn't help but stop and stare, red-cheeked, at the enema bag still hanging up. "Don't worry," Robin smiled as she saw Sierra's expression. "You didn't hold it the whole time, but I think you've had enough for today. In the future, though, you'll have to use your help." Sierra's eyes darted back over towards the butt plug sitting on the sink, and she resolved to do her best to make sure she didn't get another enema.

She was so worn out from her day that she didn't even protest when Robin tucked her into bed, gently pulling the glasses off her face and setting them on the table by her bed. "Sierra," Robin said gently, sitting on the edge of Sierra's bed, "Your father told you that he gave me permission to spank you, didn't he?"

Sierra gulped and squirmed. "Y-Yes," she had to admit. "B-But I'm an adult! You need MY permission!"

"And do I have it?" Robin asked.

Sierra fidgeted, realizing she'd walked right into that one. Thanks to her braces, there was no way not to say yes. "D-Do I need one?"

"Yes, you do," Robin said sternly. "You've behaved very badly today, and if that enema hadn't upset you so much, you would be going to bed with your bottom just as pink as your diapers. Don't think that will work again, though! I'm going to make you into a nice, proper young lady, even if we have to start over again from the beginning! Now, do I have your permission to spank you if you act up again?"

Sierra somehow doubted that it really mattered, but she sighed and said, "Yes," anyway, if only to end this conversation. None of what had happened today was even her fault! But she didn't want to give Robin an excuse to change her mind by 'arguing' with her.

"Thank you," Robin smiled, kissing Sierra on her forehead. "That's surprisingly mature of you. Goodnight, Sierra."

Sierra curled up, plastic sheet and diaper crinkling all around her, and contemplated the huge mess she'd gotten herself into this time. Now that her mind was working again, it was easy to figure out just what those diapers did. They were affecting her mind, making her mentally regress further the more she used them, until she was just a babbling, incontinent baby. Luckily, it only lasted as long as she was wearing the diaper. Less luckily, once the diaper was on, she couldn't take it off herself, meaning she had to either beg to use the toilet like a potty training toddler, or hope she wouldn't go enough to trigger the effect.

And, as she laid there and squirmed, she slowly began to remember what her father had been saying to her on the phone when she'd been trying so hard not to poop her pants. "By the way," he'd told her, "You must have filled out the missing luggage form incorrectly, because I just got your suitcase here this afternoon. You know you were supposed to put the address of your hotel, right? Well, it sounds like Robin's made sure you have plenty of clothes there, anyway. Make sure to thank her for that!"

Sierra whimpered as she squirmed under her covers, her bladder already feeling like it was going to explode, and make her diaper start draining her brain while she laid there. Her real clothes, the ones that might have a chance at hiding her infantile underthings, weren't coming. And, worse, neither was the wand she had packed away in her suitcase. She had no hope of breaking free of all of these spells Samara had cast on her new clothes, including this one on her diapers, until she got back home!
