"Please," Sierra pouted. "Please, Ms. Haley, can you just...?" No matter how much she wanted it to be done, it was hard to say it out loud, to admit what had happened, even though there was no doubt both of them knew what had happened.

"Come on, Sierra," Haley urged. "If you can't say it, it must not be that important."

Sierra glared at her, stomping her foot, squeaking as Haley shrugged and turned, tugging on the leash, pulling Sierra forward a few more steps, the mess in her diaper squishing and squelching between her legs with each one. "P-Please!" she tried again, after feeling that. "C-Can you ch-change my... my p-poopy Pampers?"

"Sure, I could," Haley shrugged, turning back towards her victim, kneeling down to look her in the eye. "But will I? I don't know about that. You see, while I'm kind-hearted enough to look after a baby like you for free, I'm afraid messy changes are extra. Honestly, for someone like you, they're basically your default state of existence, aren't they? I'd think you'd be used to them by now."

"No, they aren't!" Sierra stomped her foot in a huff. "And no, I'm not! I'm not a baby!"

She squeaked as Haley delivered a hard spank to the seat of her diaper, keeping her hand there, giving the mushy lump a rub as she teased. "Aren't you? That's not what it feels like, baby Sierra. It's usually better to just leave babies like you in your Pampers a while. You get more obedient and sweet after a while, and diapers are expensive. But my offer still stands. I'll look after you for free, but if you want a change, you have to pay my babysitting rate."

"How about you just leave me alone?" Sierra asked. "I-I can take care of it myself if you just..."

"You're such a funny baby," Haley chuckled. "Now, what's your decision, Sierra?"

Sierra whimpered, squirming in her messy diaper. She had some more cash with her, in case she wanted to do more shopping after showing off her Victoria's Secret bag, but she was going to need to pay for the bus ride home, too. "H-How much is it?" she sighed, hoping she had enough.

"Ten dollars," Haley replied.

"Seriously?!" Sierra stared up at her. She could afford it, sure, and still be able to afford her ticket back, but that still seemed awfully expensive for a single change, especially when it was Haley's fault she'd used the diaper, and was in it in the first place.

"Okay, fifteen," Haley shrugged. "There are a lot of boosters in there, and those cost money, too. Or you can wait. I'll probably get tired of smelling you eventually. Although, I do babysit a lot, so I'm pretty used to it."

"Fine!" Sierra sighed, trying to reach behind herself to unzip the backpack so she could get her purse out.

"Well?" Haley teased. "Come on, let's see the money, Sierra."

Sierra glared at her. "You know where it is! Just give me my purse and I can give it to you!"

"You seem to think you're such a big girl," Haley grinned. "Get it yourself. Or do you not want a clean diaper?"

"I'm trying!" Sierra whined, stomping her foot.

"Sierra, if you don't stop throwing a tantrum, I'm going to spank you right here in the middle of the mall. Is that what you want, young lady?" As if to demonstrate, she gave Sierra's diaper a hard thwack, giggling as she watched the smaller blush and squirm as the mess inside was squished.

"Just let me take my backpack off, and I can get it," Sierra sniffled. "This isn't fair!"

"I'm certainly not doing that," Haley shook her head. "Not after what happened last time."

"Then how am..?!" Sierra demanded, pouting as she was pulled into motion again.

"Not my concern, little girl," Haley told her. "But you aren't getting a change until I get that money." In motion, getting the bag unzipped to reach her purse was even less likely, so Sierra could only stumble on, trying to keep up with the cheerleader's longer stride, following along reluctantly, but obediently, until she saw where they were so clearly headed.

"Wh-What do we need here?" Sierra asked, gulping, eyes widening as she stared at the sign.

"You could use all sorts of things from here, I'm sure," Haley said. "I'm here for diapers, though. They're so big and poofy, I only had room for one in my purse, so if you want a change, I need to buy more."

"Oh," Sierra blushed. She did, definitely, want a change, and that made sense, so, no matter how little she wanted to be seen there, she let herself be taken inside.

"Hello!" the cashier chirped from behind the register. "Can I help you?"

"No, we're good," Haley replied. "We're quite at home here, aren't we, Sierra?"

Sierra blushed and shook her head, looking around, a bit overwhelmed as she took it all in. She'd seen the store there before, of course, but she'd never been inside. She'd never felt the need, and, honestly, something about it had always scared her a little.

It was a baby store, but calling it that did it a disservice. It was quite large, as it had moved into the spot of whatever anchor store had been there initially, so it stretched on and on, with, from what she could see, just about anything you could want to take care of a baby inside. As an anchor store, it had its own exits outside, too. In fact, those were the mall entrances closest to the bus stop, but Sierra always walked the little bit extra to get to the main mall entrance instead.

"No, silly," Haley chuckled. "I didn't mean your actual home, just that we're here all the time to get you new diapers and things." Haley swatted Sierra's bottom again, and, as much as Sierra didn't want to give her the satisfaction, she couldn't help squealing in surprise at the initial impact, then wiggling and blushing. "Come on, we'd better go do that."

They didn't go to the diapers first, however. There was a section for clothes, and Haley led Sierra straight to them, browsing while Sierra looked around anxiously, hoping nobody saw her there. "I don't need anything here!" Sierra whined, trying to tug at her leash and pull Haley away. "I won't fit into it anyway!"

"But these are made for you!" Haley told her. "These are baby clothes, and that's what you are. I bet if they don't have your size, we can take them up to that nice cashier and she can order them for you, if you ask sweetly. Is that what you want to do, Sierra? Do you want to toddle up to the nice lady in your loaded Pampers and ask her to order you some more appropriate clothing?"

Sierra blushed, shaking her head. "N-No, Ms. Haley," she mumbled.

"I didn't think so," the bigger girl nodded. "Good thing you're enough of a baby we shouldn't have to. I think this will do nicely."

"Hey!" Sierra gasped, trying to swat Haley's hands away from her shortall straps. "What are you doing?!"

"This will just take a second," the cheerleader assured her. "We'll try these on, and..."

"Not here!" Sierra turned bright red at the thought of getting stripped down to her diaper and shirt out in the open here. "There's fitting rooms right over there!"

"I just thought it would be quicker here," Haley shrugged. "Don't worry, nobody here will care if you show off your little Pampers."

"No!" Sierra exclaimed, a little louder than she intended, stomping her foot. "No, no, no! You're so mean!"

"Sierra, calm down," Haley told her. "I'm just looking out for you."

"No, you aren't!" Sierra stomped some more, fuming at everything this girl had put her through. "You're just being a big... meanie!" There were other words she could have called her, but she was in control of her anger enough to realize there were probably kids around. "You have been all day, and I hate you!"

"Sierra!" Haley pretended to be shocked. "That is not very nice at all! Come on!"

She picked up the still upset witch, not even bothering to let her walk on her own, carrying her to the fitting room. "I am so sorry for that outburst," she told the attendant, shaking her head. "I think she needs an early nap today."

"I think you may be right," the attendant smirked, making Sierra blush, realizing the girl, who was definitely younger than her, had seen it all.

"We just have this," Haley showed off what she'd picked. "We might be a little while, though," she gave Sierra a pointed look.

"That's fine," the attendant smiled. "Take the big one there."

Sierra wasn't really sure what was going on, although that may have been because she didn't want to believe it. Haley and the attendant seemed to be on the same wavelength, however, as Haley carried her into the largest fitting room, locking the door behind her and taking off her backpack, hanging it up on a hook that seemed designed to keep things out of the reach of the little ones who were being brought in here to try stuff on, and that worked pretty well on her, too.

"I don't wanna try it on," Sierra pouted as Haley began to undo the straps on her shortalls. "I just want you to buy the diapers and change me, already!"

"Clearly, you need a reminder of who's in charge, then," Haley said, her tone instantly telling Sierra she'd made a big mistake somewhere. "I don't care what you want, Sierra. You're just a little, stinky diaper baby, and I can do whatever I want with you."

"B-But..." Sierra backed away, gulping nervously. "I-I'll pay you for the change, and..."

Haley grabbed at her and Sierra spun to try and run away, although, even in the largest fitting room, there wasn't far for her to go. She wasn't fast enough anyway, feeling the cheerleader's hands close around the back of her plastic panties, reaching in to grab the waistband of her diaper as well before giving them a pull.

Sierra squealed, feeling them creeping up her bottom as she was given a vicious wedgie. "S-Stop!" she whined, immediately regretting it as Haley lifted harder, Sierra's feet kicking wildly as they were raised off the ground, and she was left dangling there, squirming and blushing in discomfort. "Haley, s-stop!" she gasped.

"Wrong," Haley said, giving Sierra a bounce, watching her wiggle more desperately to escape. "You don't tell me what to do, do you, little lady? And you don't get to call me that, do you? You're just a naughty little girl, and you don't deserve to address me like an equal, do you?" When Sierra didn't answer right away, she bounced her again. "Do you?!"

"N-No, Ms. Haley," Sierra sniffled, just wanting to be let down. Haley didn't do that, however. Instead, she carried her over to the bench, dangling from her grip, desperately squirming all the way, then sat down and flopped the girl over her lap, bottom up. "M-Ms. Haley, I-I'm sorry!" Sierra squealed, whimpering as she felt Haley grab her arms, easily pinning them to her back with one of her hands, leaving her trapped and vulnerable. "I-I'm really sorry, a-and I won't... Ow!"

Everything she'd gotten before had just been a light warning, compared to the spank she got then. Instantly, tears sprang to her eyes, and she felt her diaper warm slightly as she whimpered, certain she could feel her bottom turning pink already. And that was through her diaper! "I-I'll be really good!" she swore. "I-I'll be the best baby ever for you, and... Ouch!"

She wriggled, blushing, feeling how the mess had squished around even more with that spank, making the whole experience all the more mortifying. "Sorry, Sierra," Haley said, not sounding the least bit sincere as she rested her hand on the seat of the girl's diapers, giving them a rub, "but this is for your own good."

Within the first handful of spanks, Sierra was sobbing, from both pain and humiliation. She hoped the attendant would come in and intervene, but then she remembered the girl's expression, and had a feeling she'd known exactly what was coming, and approved of it. By the time it was over, Sierra's bottom felt hot, and red, and swollen as it throbbed beneath her now quite filthy diaper, the mess seeming to be touching every part of her underneath the garment, giving her no escape as she was stood up in the corner, her thumb pushing its way into her mouth as she sniffled, not caring when she started to suck on it in front of Haley.

"That is too cute!" Haley exclaimed. Sierra could hear snapping sounds behind her, and knew she was having her picture taken, but she tried not to think about it too much until Haley turned her around. "Look at you," the cheerleader smirked. "Did I tell you to suck your thumb, baby?" Sierra shook her head shyly. "Then why are you doing it?" Haley asked. "Is it because you're just a baby?" The real explanation was more nuanced than that, in Sierra's opinion, but she wasn't in any state to argue the point, so she gave in and nodded.

"Just as I thought," Haley finished recording her video, setting her phone down with a smile, pulling Sierra's shirt off. "And babies don't need these, do they?" She removed Sierra's bra again, tossing it under the bench, chuckling when Sierra didn't remove her thumb from her mouth, just tried to cover herself with her other arm. "And you're not getting it back this time. There's no point, is there?"

"B-But Ms. Haley," Sierra mumbled behind her thumb.

"You just told me you're a baby," Haley reminded her. "And babies don't wear bras. Whoever comes in here next is going to be so confused where that came from." She chuckled, picking up the outfit she'd picked out. "Now, why don't we try this on?"

They were pajamas, though clearly made for a toddler, at best, and not a young woman in her twenties. The top was pink, dotted with strawberries, with a pair of pockets on the front and a row of buttons up the center. Haley gently extracted the girl's thumb from her mouth long enough to get her arm into the sleeve, then knelt down to fasten the buttons up, each one making Sierra more anxious, more worried that she was wrong, and this thing really was going to fit her, which made her feel even smaller and more helpless than she had after her spanking.

"See?" Haley smiled. "Perfect! Just like I thought!"

The bottoms could barely be called that. They were really just a diaper cover, with the same strawberry design as the top, and a row of big, poofy ruffles on the back. Once they were on, Haley turned Sierra around to give her the full view.

Sierra gulped, sucking a little harder on her thumb as she stared at what she would have assumed was a baby, ready to go to bed, if she didn't know better. The shirt was a bit short, although she wasn't sure if it was meant to be or not. It stopped short of the top of the diaper cover, allowing a bit of the diaper's waistband to show, while some of it was also visible through the cover's legholes, ensuring everyone could tell what she was wearing underneath.

"I love it!" Haley exclaimed, kneeling down behind Sierra, holding her in place, keeping her from turning away from her reflection as she leaned down and asked gently in the girl's ear, "What do you think, Sierra?"

This was a test. Sierra knew that, and she knew she couldn't make it through another spanking right now. So, despite being very sure she'd never want to be caught dead in this again, she said quietly, "I-I love it, too, Ms. Haley."

"I had a feeling you would," Haley grinned. "I know you think I'm mean, sweetie, but to prove I'm not, I'm going to buy this for you as a gift, so you can always remember today."

Sierra's free hand wandered to her bottom, rubbing it through her diaper, worried there could be a permanent mark under there to commemorate this awful day. "Th-Thank you, Ms. Haley," she forced herself to say anyway.

"Aww, you're welcome," Haley pulled her into a hug. "Now," she said, keeping Sierra in her arms, "tell me I'm the best babysitter ever, and you're going to stop being such a brat, now that you know what happens when you are."

Sierra had done plenty of babysitting herself, and, while she considered herself a pretty good sitter, her track record of winding up in diapers beside her charges, or instead of them, indicated otherwise. Even so, she still knew she was better than this bully. But she made herself tell her, "Y-You're my favorite babysitter, a-and I'll be good for you from now on."

"I doubt it," Haley gave her a tap on the bottom, much lighter than even the ones she'd given the girl before the spanking, though still enough to make her yelp after that. "But thank you for saying it."

True to her word, Haley didn't put Sierra's bra back on her after taking off the PJs, and Sierra didn't dare try to retrieve it herself. Haley did let her have her backpack long enough to get out her purse, however, and reluctantly hand over fifteen dollars. "C-Can we go get more diapers now?" she asked. "P-Please?"

"Of course we can!" Haley nodded, sliding the money into her own purse, and putting the harness back on Sierra. "Why don't you go ahead and go back to sucking your thumb again?"

It sounded like a suggestion, but Sierra wasn't sure it really was. And, honestly, she didn't take much convincing anyway, feeling much better, despite how much her bottom hurt, as she toddled out of the room once she had her thumb in her mouth. She stared down at her feet, not wanting to look at the attendant as she shuffled away, letting herself be led away.

She had no idea where the diapers were, and she couldn't bring herself to raise her head from the floor tiles below her, so, as far as she knew, Haley could have been taking her anywhere. She hoped, after what she'd put Sierra through, she was going to take it easy on her, and really was going where she'd claimed.

When they stopped, however, Sierra could tell they weren't in the diaper aisle, even before she heard Haley squeal, "Hey, Courtney!"

"Haley!" another voice exclaimed. "What are you doing here? And who's this?"

"Go on," Haley pushed Sierra forward. "Introduce yourself."

Sierra gulped, staring up at a new girl, around Haley's age. She wasn't quite as tall, although she still towered over Sierra, and looked very pretty, despite the rather conservative dress she was wearing, with a large nametag attached to the front. "I-I'm Sierra," she said.

"Sweetie, remember, you have to take your thumb out first," Haley teased, making Sierra blush, hardly able to believe she'd forgotten. "I'm babysitting her," Haley explained to Courtney.

"You're always babysitting!" Courtney chuckled. "You must be great at it! Is she?" She knelt down to look Sierra in the eyes, her tone making it obvious she didn't see her as anything more than a child.

Sierra gulped, feeling Haley putting a little more pressure on the leash, reminding her she was there, warning her to behave herself without a word. "Y-Yeah," Sierra lied. "Sh-She's the best babysitter ever..."

"That's what I've always heard," Courtney nodded, giving Sierra a wink.

"I didn't know you still worked here!" Haley claimed, although Sierra doubted that. "You get off in time for the demonstration tonight, don't you?"

"Of course!" Courtney said. "They don't let me wear my uniform here, though. It would be so much more convenient than having to change here, but whatever."

"So," Haley said, "what's this?"

"I'm giving out samples today," Courtney told her, sounding frustrated. "Or I'm supposed to be, anyway. Nobody seems interested."

"Well," Haley grinned, "what a funny coincidence. Sierra here hasn't eaten yet today, despite my best efforts, and she's getting awfully grumpy. I bet she'd be happy to help you out."

"Oh, I don't know," Courtney shrugged. "This is really for babies. I think she's a little too old for it."

"You'd think she'd be too old for diapers, too," Haley gave them another tap. "I don't think it'll bother her too much. It's better than nothing, isn't it, Sierra?"

Sierra whimpered, staring back at Haley, the expression on the girl's face keeping her from even starting to ask if she was serious, or trying to change her mind. "Y-Yeah," she nodded, even though her tummy still felt awfully full from all that soda with fiber she'd drank.

"That would be a huge help!" Courtney smiled. "The sooner I do this, the sooner I can start getting ready for the show! You can have all you want, sweetie!"

"Can we move one of these?" Haley asked, nodding towards something, and Courtney shrugged, taking Sierra's leash as Haley picked up one of the display high chairs from a few feet away, moving it to beside Courtney's sample table.

"Does she really need that?" Courtney asked.

"Yes, she does, believe me," Haley rolled her eyes, taking Sierra's harness off, then lifting her directly into the chair, locking the tray on. Sierra squirmed, trying to find a comfortable position on her spanked, messy bottom. "And don't let her out until I get back. She's a cute girl, but she likes to run."

"I-I won't do it again," Sierra claimed, but it didn't look like either of the other girls bought it.

"And feel free to give her as much as you want," Haley told Courtney, setting the backpack down on the floor. "She's going to be a good girl and finish every bite." Haley ruffled Sierra's hair, then patted her on the knee. "Aren't you, Sierra?"

Sierra gulped, wiggling in her seat, knowing, despite how little she wanted any of what she now saw were little bowls of baby oatmeal and cereal on Courtney's table, that she didn't have much of a choice. "Y-Yes, Ms. Haley," she nodded reluctantly.
