Sierra looked up at Robin, eyes wide as she looked at the empty bag she'd just been given. "Wh-What?" she squeaked.

"I know you heard me, young lady," Robin sighed. "Now get to work."

Sierra pouted, not wanting to do as she was told, but too scared not to. It had already been a long morning, being taken downstairs for breakfast in her PJs, knowing her diaper was incredibly obvious under them, begging Robin not to give her an enema to make sure she was cleaned out for her time with the babysitter later that day, and getting dressed for the day. The afternoon and evening before had been even longer, and more humiliating. She'd had her dirty diaper changed by a stranger, gotten spanked by Robin, then spent the rest of the day in bed, too scared to ask to be let up even to go to the bathroom, so she just laid there, feeling her double diaper get soggier, chipping away at her mind with every little accident.

She really had made an awful mess of her new clothes the day before, digging through all the bags in a futile attempt to find her swimsuit bottoms. She supposed it was only fair that she be the one to clean it up, although if she'd known Robin would use that as an excuse to dress her like a doll, she would have done it much sooner, preferably yesterday after being put down for her nap by her new babysitter, while Robin was still at the pool.

Sierra had her diaper on, of course. She was starting to worry she'd never get to go without it again, at this rate. Over top of that was a pair of tights, with rows of ruffles across the backside, easily visible under her pink, lacy dress, its skirt held almost straight out by layers of petticoats. Sierra didn't remember trying all of this on at the store, making her wonder if Samara had added that into the cart without her noticing, or if she'd just tried on so many things that she'd actually forgotten.

"Okay, okay," Sierra sighed, bending down towards the piles of clothing.

"No," Robin stopped her. "You know better than that, don't you?"

Sierra stared up at her blankly for a moment, then sighed again, barely keeping herself from rolling her eyes. "Yes, ma'am." That had been one of the things they'd 'discussed' during her spanking the night before, how she needed to show Robin more respect. Sierra had wanted very much to point out that this whole thing had started, supposedly, as a way for Robin to get to know her as an equal but it seemed like bad timing, plus, she'd been bawling too hard to speak clearly anyway.

"That's better," Robin nodded. "Go on."

Sierra began going through the clothes, re-folding them and trying to organize them, at least a little. She really had forgotten about a lot of these outfits, she realized, and none of them were things she would have chosen to wear, even before she'd been sentenced to diapers. With them, nearly all of them were going to make her padded state immediately noticeable to everyone around her.

She froze as her fingers brushed against plastic, her eyes bristling with tears as she saw the package of day of the week panties they'd bought. They'd looked so silly in the store, with their goofy cartoon animals, but now, after so long in Pull-Ups and diapers, she would have gone for them in a heartbeat, even if her glasses meant she would have to ask someone else which ones she was supposed to wear which day.

"Put those up on the bed," Robin ordered. Sierra looked up at her hopefully, thinking that maybe the woman had changed her mind about Sierra's punishment. "We're taking those back, since you obviously have no use for them."

"Yes, ma'am," Sierra sighed.

"And you might as well put those Pull-Ups there, too," Robin said. "We can't take those back, of course, but we'll take them over to Chloe so she can use them at night. From what her mommy was telling me, she's just about done with them then, too, so this might save them from having to buy any more."

Sierra stared at the still mostly full package, her lip quivering as she lifted it, the thought of having to turn it over to some little girl, who was on the verge of being promoted out of them, because Sierra herself had been demoted back to diapers for the foreseeable future, was mortifying. And Chloe already thought of her as a baby anyway, despite how much younger she was.

Sierra was sure that would be the worst thing that could happen during her cleaning session, but she was proven wrong after a little more work, once she moved aside another dress and found what looked at first like a loose pair of underwear, even though that was one thing she knew wouldn't have been in with the things Robin would have bought for her. Only when she saw Ariel did she realize that it was actually the bottoms to her swim suit, the ones she'd been so desperate to find the day before that she'd made this mess in the first place.

She hoped Robin wouldn't notice, but the woman seemed to recognize them at the same time. "And what are those?" she asked pointedly.

There was no point, other than making herself feel better, to lie. Besides, even if it would have been nice to say something different, Robin could, and likely would, discover the truth, then be even madder. "The bottoms I was looking for," she picked them up.

"Well, look at that," Robin raised her eyebrows. "Your friend didn't take them after all, did she?"

"Yes, ma'am." Sierra's eyes widened as she realized what she'd said. She'd just been trying to answer Robin, like a good girl, forgetting that one of the intricate cobweb of spells on her kept her from being able to say 'no', like she'd expected.

"Oh, really? Then why are you holding them right now?" Robin demanded.

Sierra had no idea how to fix this, or make Robin less mad at her, so she shrugged. "I'm sorry, ma'am."

"I think the person you should really apologize to is your friend," Robin said. "And I think you might as well put those with your panties, since you never wore them. Your swim diapers work just fine, and are much cuter, so you have no need for them."

"What?!" Sierra squealed. "B-But why can't I wear these over my swim diapers?" After the accident she'd had in those the day before, she wasn't even going to try to convince Robin she didn't need the diapers. "Everyone knew what those were yesterday! It was so embarrassing!"

"Oh, don't be silly," Robin shook her head. "Nobody was paying attention to what you were wearing." As if to emphasize that point, she said, "And we can take that second pack of training bras back, too, I suppose. One pack is more than enough for you for right now." Sierra wished she could have argued the point, but Robin hadn't even bothered to put her in one that morning, and it didn't matter one bit. The spell on them had left her quite flat, even when she wasn't wearing them, and she could only hope that a little time without having one on would cause what little she'd had to begin with to start coming back, though that would probably prompt Robin to have her wear them again, and start the whole cycle over again.

"Good work," Robin complimented her as she finished her sorting and folding. "Now, put all that stuff we're returning into a bag, and I'll take a quick shower so we can get going. And don't try anything funny, young lady, I'll be checking the bag before we leave!"

So, while the sound of water pattering in the other room magically filled her bladder, leaving her squirming desperately in a matter of seconds, Sierra reluctantly filled one of the empty shopping bags with the most mature things she'd gotten to buy during that trip. That really wasn't saying much, which meant that Robin being convinced Sierra was no longer mature enough for even them was even more humiliating.

Because of all that, Sierra was more desperate than ever not to give into her aching bladder, knowing that using her diaper meant acting more babyish and proving that Robin was right. She squeezed her legs together as much as she could, then pressed a hand to her thick diaper, toddling as far away from the bathroom as she could, but the room wasn't big enough to escape the sound.

Somehow, through a lot of bouncing and pushing on her diaper and whimpering, Sierra made it. The sound of water stopped, a sense of relief washing over her, even though she still had to wait for Robin to get dressed. It was a light at the end of the tunnel, though, and she was waiting outside the bathroom door, nibbling her bottom lip. "Can I please use the bathroom, ma'am?" she begged, wanting to sound as polite as possible to keep Robin from having any excuse to say no.

It turned out not to matter. Robin looked down at her, in the middle of her desperate squirming, and said, "Sorry, Sierra, but no."

"What?!" Sierra whined. "B-But..."

"I just don't think there's any point right now," Robin told her. "I'm glad you realized you had to go this time, but from what I've seen the past few days, I don't think it will happen often enough right now to bother with. It will just be easier for everyone if you get used to your diapers."

"B-But that's..!" Sierra sniffled, wanting to complain about how not fair this was, but knowing she couldn't because of the spell on her braces, staring past Robin to the toilet, mere feet behind the woman. But even if she pushed past her, she couldn't get these diapers off by herself, unfortunately.

"I know," Robin said condescendingly, apparently knowing exactly what the girl would have said anyway, "but your Daddy put me in charge, and this is what I think is best."

Sierra did remember her dad saying Robin was in charge, but she hadn't thought it was over everything, including whether she even got the chance to try to use the bathroom somewhere other than her pants! "I wanna talk to him!" she insisted, crossing her arms. After what a fuss Robin had made the past few days about Sierra supposedly not trying, she couldn't accept this.

"Maybe later," Robin told her. "You know he's working right now. Come on, we need to get going, pick up your things." When Sierra shook her head, she threatened, "Do I need to get the hairbrush? It's right there."

That sent Sierra scrambling, since she could see that large, wooden hairbrush on the counter. She grabbed the bag and trotted back to the woman obediently, but unhappily. "The Pull-Ups, too," Robin reminded her. Sierra glared, but stomped over and picked them up, too, her clumsiness nearly making her trip over herself and ruin the angry air she was projecting.

Robin led her over to Chloe's room, knocking on the door, then pushing Sierra in front of her. "M-Maybe they left already," Sierra suggested after a moment. That was the best she could hope for at this point as she wiggled, her hands too full to press on her diaper, like she really needed to right then, her bladder feeling like it was on the verge of bursting.

The door opened, revealing Chloe's dad, making Sierra even more aware of her super visible diaper as she stared down at the floor. "U-Umm, I..." she stammered, gulping as she noticed the sound of water running from their bathroom and realized Chloe's mom was likely in the shower.

"Hold on, I'll get her," he told her. Sierra looked up to try to stop him, but he was already gone, and she had another problem. She bit down fiercely on her bottom lip as her bladder begged for relief as it started filling again with this fresh batch of water sounds, but it wasn't enough. She gasped, squirming as she felt a trickle of warmth begin making its way into her diaper, right as Chloe appeared, looking annoyed at being pulled away from whatever she had been doing.

"Umm..." Sierra's cheeks burned, feeling suddenly shy. She wasn't sure if it was just because of what was happening, or if her accident had already set off the first level of the spell on her diaper, but either way, it was suddenly even harder to speak. "I-I brought you..." She stared up at Robin for help, and got nothing more than a nod. "Th-These are for you!"

She shoved the Pull-Ups into the girl's arms, then immediately planted her thumb into her mouth, leaving it there for a moment before she realized what she was doing and blushingly removed it, wanting nothing more than to hide behind Robin. The spell was definitely kicking in now, she thought, which made sense, since she hadn't stopped peeing, and her diaper was feeling soggy now.

"I don't need these!" Chloe turned up her nose.

"Oh, Chloe, you know you still have trouble at night sometimes," her dad said. "And we are almost out. These will be very useful, thank you, Sierra." He bent down and smiled at her, as if she actually were his daughter's age. "Say thank you, Chloe."

Chloe pouted. "I'm not gonna use them," she huffed. "I don't pee my pants like her!" She pointed at Sierra's diaper, making the much older girl's heart nearly stop as she felt the adults' eyes turn there. She hoped they would think Chloe was talking about earlier times that had happened, but Robin bent down and gave her diaper a pat, shaking her head.

"You still need to say thank you," her father tried again diligently.

"Fine," Chloe rolled her eyes. "Thank you, baby, for your baby pants."

"Chloe!" her father reprimanded her.

"No, it's okay, Sierra has been acting very babyish lately. But you are wrong," she winked at Chloe, giving Sierra's still dampening diaper another pat. "These are baby pants, those are for big girls like you. Now, come on, Sierra, we need to get going."

Sierra waited for Chloe's dad to close the door, his daughter pouting down at the Pull-Ups unhappily, before asking, "C-Can I have a change, ma'am?" That encounter had been humiliating enough, she didn't want to parade through the hotel in her wet diaper, much less go to the store.

"No, I don't think so," Robin shook her head, heading for the elevator. "You didn't feel that wet yet, and you should get used to the feeling, I think. Besides, those diapers are meant for long term use, and I think we need to make sure we get our money's worth, don't you?"

"But I want a dry diaper!" Sierra whined. "You don't even hafta let me try Pull-Ups again, I just want another diaper!"

"We had this discussion already," Robin told her sternly. "I am in charge, young lady, and if I say you're staying in your wet diaper, that's what's going to happen."

And it definitely did. Sierra helplessly felt the squishy padding of her diaper grow slowly cold and clammy as they got into a car and drove to the store, then waited in the long line at the customer service desk, with her blushing whenever anybody walked past them, positive they were staring at her. Finally, they reached the counter, and Robin made her put the bag onto it and say why they were there. "I-I need to return these," she blushed as the worker began digging through the childish things.

"And why is that?" Robin asked.

Sierra glared at her, positive the woman was doing this to humiliate her, that her suspicions were definitely right about her, and she was just an evil nanny robot from another dimension after all. "B-Because..." Sierra knew Robin was looking for her to admit she didn't need the things anymore, but the spell that kept her from saying anything negative meant that was impossible. "I..." What else could she say to keep Robin happy?"

"Were they too small for you?" the worker asked helpfully.

"That's definitely not it," Robin scoffed. "Go on, Sierra, tell the nice lady."

What was she going to do? She couldn't say she didn't want it, or couldn't use it. "I... I have to wear this instead," she finally said, awkwardly gesturing at herself and blushing, very nearly putting her thumb in her mouth again.

"Well, you do look rather cute in it," the worker smiled. "Now, there isn't a receipt in here. Do you have that?"

"Sierra?" Robin asked. Sierra's eyes went wide. She hadn't even thought of that, and while she could have blamed Robin for not reminding her, she knew that wouldn't go over well. If she wanted to prove she was mature after all, she should have been able to think of something so basic on her own.

"I can still return them," the woman said, "But it will be for store credit."

"That's fine," Robin shrugged. "We'll definitely find something else for her here. Do you know if Samara is working today?"

Sierra gulped at the sound of the name. She didn't want to see her, not now, not like this! "I don't know anyone here by that name," the woman behind the counter shrugged. Yes! Sierra smiled triumphantly. Robin wasn't going to trust her now, no matter what, but maybe she'd listen to this person and see that Samara had been lying to her all along on their last trip. "I'm pretty new, though, so I don't know everyone."

The woman handed the gift card with the store credit to Robin, not Sierra, and Robin led Sierra back to the children's section to shop, but Sierra still didn't feel quite as anxious as she had when she'd first stepped into the store. After all, she knew that Samara didn't really work here, and if she hadn't shown back up yet, then she was probably safe.

"Hi, there!" Right on cue, she heard the girl's voice, and, moments later, she was at their side, giving Sierra an extra tight hug. "Back again? Getting a head start on back to school shopping?"

Sierra's eyes widened, hoping Robin wouldn't pick up on that last part. Thankfully, when she responded, she said, "No, we had to bring back a few things."

"I can guess what," Samara gave her a wink, leering at Sierra's diaper.

"Yes, you were right," Robin chuckled. "I thought I'd give her a chance, though. Anyway, Sierra forgot the receipt, so we have some credit to use up."

"I see," Samara nodded. "You know, you bought her an awful lot last time, maybe you should get yourself something. Why don't you go look around the women's section? I can keep an eye on Sierra, and we can catch up!"

"You have work to do," Robin said, and, for once, Sierra found herself enthusiastically nodding in agreement. "I wouldn't want to impose."

"It's fine!" Samara insisted. "I'm just straightening up over here anyway. Go on!"

Sierra watched Robin walk away with big eyes, turning back to Samara to see the girl there, wand out, grinning. "Look at you," she sneered. "I never imagined those spells would work this quickly. You're just a big baby, aren't you? But, then again, I guess you didn't have far to go."

"Samara, please," Sierra pleaded, only for a pacifier to fly into her open mouth as Samara stepped closer to her, pushing the tip of her wand into the crotch of Sierra's wet diaper, making the girl squirm. Sierra was sure she could feel magic, but with so many other spells on her already, it was hard to tell if it was anything new or not. She reached up to pull the pacifier out, blushing, and instantly felt wetness at the corners of her mouth, starting to drip down her cheeks.

"Babies like you don't have anything important to say," Samara said. "So you might as well keep that or your thumb in your mouth. That's the only way to keep from drooling."

Sierra blushed, reaching up to wipe her face, but that only dried it for a moment. "Samara, please, take these spells off me!" she begged. "You're a better witch than me, okay? Is that what you want to hear?"

"Of course I am," Samara sniffed. "I'm not the one running around in a diaper."

Sierra's cheeks darkened, but, much worse, she felt a rumble in her tummy. No, not now, she thought. Of all times, this was the worst! "And you did it," Sierra admitted. "You made me this way, n-now, please, change me back."

"Change you back?" Samara shook her head. "But you look so cute there in your big, thick, pink diapers." Her voice got louder and louder with each word, until Sierra was sure everyone in the department could hear, and was looking at them. Her stomach was feeling fuller and fuller, most likely because she was so nervous about how much attention was being drawn towards her.

Anxiously, she tugged at her skirt, trying to will it to be longer and actually hide her diaper, only to gasp as a cramp wracked her out of nowhere, leaving her clutching her tummy instead. What had Samara done?! She hadn't done that yet today, but she hadn't had to go nearly this badly just moments ago! She was sure it had to be because of the other girl, but what could she do about it?

"Mommy, is that girl wearing a diaper?" Sierra's cheeks burned as she heard the voice, another cramp hitting her and doubling her over, even as she tried again to pull her skirt down lower. That was almost the last straw, as she felt a push from within herself, and a gooey feeling starting to spread around the seat of her diaper. She felt her mind go a little foggier as tears sprang to her eyes, but with a little struggle, she managed to stop herself.

At least, until Samara loudly reprimanded her. "Sierra! I hope you aren't doing what I think you're doing, young lady! You promised me you were going to keep that diaper clean this time!"

If anyone nearby hadn't already been looking at her, they definitely were now. She felt ready to explode, and she knew that once it started in earnest, there was nothing she would be able to do to stop it. The more she used her diaper, after all, the harder it was to stop herself from using it further, as her potty training worsened the more her mind was regressed.

"Please, Samara," she sniffled, clutching at the girl's shirt. "I-I'll do whatever you want!"

"Oh, Sierra," Samara giggled. "You might as well get used to it, you're going to poop your Pampers right here in front of me, and there's nothing you can do about it. But, if it'll make you feel better," she flicked her wand, "your mind won't go back any further, this time. It's just temporary, though, so don't get used to it, I just want to make sure you understand what's happening."

Sierra felt a sense of relief flood over her, but it was short-lived as she reflexively grabbed for her skirt. As soon as she gave it a yank downwards, another cramp hit, and this time, it was too much. Her cheeks grew wet as she felt her diaper expand out behind her, her knees bending as she grunted, knowing that any customers in this department would know very well what she was doing just by seeing her. Worst of all, the more she went, the further her diaper sagged, making it even harder to even think about keeping hidden, although she couldn't help but try.

"Oh, my God," Samara snickered, watching with a hand over her mouth. "You really don't understand, do you? I guess you had used your diaper a little before I paused the spell, but really, that's sad. Hey, little miss poopy pants, do you know why you're messing yourself right now? Or are you just so used to it that you don't find it strange?"

Sierra stared up at Samara, shivering, unsure of what the other girl was talking about. "Okay, fine, I guess I'll be nice," Samara rolled her eyes, swatting Sierra's hands away from her skirt. "Whenever you try to hide your diaper like that, your bowels are going to fill a little more. But whenever somebody notices your diaper, or says something about it, the same thing will happen."

"Samara!" Sierra gasped. That was so evil! All of the outfits she had made it so her diapers were quite obvious, and likely to draw attention, and if she tried to keep anyone from looking at them, she'd just make things worse!

"Oh, and one more thing," Samara grinned. "I know you like to say you're a big girl, but now, you have a chance to prove it. You're staying in your diapers, of course, but it's your job to make sure you don't use them too much. I mean, if you want to keep what little mind you have intact, you have to do that anyway, but now, if you use them so much that they leak, your mental regression will be permanent. I wonder if anyone would even notice the difference."

"Samara, please fix me!" Sierra sniffled, dropping to her knees. "If I go home like this, I... I..."

"I'm sure you're a good enough witch to undo these spells," Samara smirked. "And if not, maybe you'll find someone else to ask for help eventually."

"You do it!" Sierra insisted. "My Daddy's gonna be so mad at me!"

"I'm sure he's used to changing your diapers by now," Samara shrugged. "If not, maybe he'll hire you a nanny. Wouldn't that be fun?"

"Samara, I'm asking nicely!" Sierra pouted. "Change me back!"

Samara knelt down, leaning in close to Sierra, making the girl squirm and blush for a long moment before whispering, "Make me."

Sierra, of course, couldn't. She couldn't even get out of this very full diaper she'd landed herself in! All she could do, while barely even realizing that's what she was doing, was flop down on the floor and begin kicking and screaming and crying, launching into a full fledged tantrum that didn't stop until someone pulled her to her feet, and she realized it was Robin. She tried to compose herself, but the regression that had already happened made it difficult, and she was still babbling and sniffling as the woman pulled her into an empty dressing room, put her over her knees, and yanked her hairbrush out of her handbag.

Given the state it was in, she left the diaper in place, and while it did cushion the blows some, it made the whole thing even more humiliating. Soon, Sierra was bawling for a whole new reason, and she was still doing just that while standing in the corner of the dressing room when Robin let Samara in.

"We were looking around, and she just squatted down and... Well, you know," Samara pretended to be bashful. "And when I told her we should find you to get a fresh diaper, she just started pitching a fit." Sierra wanted to tell the truth, but at this point, she knew Robin would side with Samara, and, to be honest, she couldn't blame her too much. "Did you at least find something for yourself?"

"I did," Robin said. "I think I'll get another package of those diapers with the rest of the credit, she's obviously going to need them. I hope I can find them when we get home, they seem to work very well."

"Don't worry," Samara grinned, "I can send you guys some."

"That's so sweet of you," Robin replied. "Oh, and you could bring us some in person. You've been so much help, I'd love to have you come to my wedding. Sierra's going to be a flower girl, and I'm sure she'll be adorable."

"F-flower girl?!" Sierra sniffled, turning around just long enough to be shot a glare that planted her nose back in the corner.

"If this trip has shown me anything, it's that you aren't ready to be a bridesmaid," Robin told her. "You should feel lucky I'm letting you do anything at this point, because even flower girl seems like it might be too much responsibility."

"I'd love to be there," Samara cut in. "Is Sierra getting out of school for it?"

Sierra froze. She hoped Robin wouldn't notice it, somehow, or think too much of it, but, sure enough, the woman said, "Oh, Sierra's out of school."

"Samara," Sierra squeaked quietly.

The girl either didn't hear, or didn't care. "No, no, she was supposed to be, but she failed, so she has to go back. She never graduated." A dead silence fell over the room for a few seconds, then, with faux concern, she asked, "Didn't she tell you?"

"No, she did not," Robin grabbed Sierra by the arm, pulling her out of her corner. "I don't think her father is going to be very happy about this." Sierra didn't have to think about it, she knew very well that he wouldn't. He wasn't going to like any of this.
