"No, silly," Valerie chuckled, grabbing Matti and pulling her in close. Matti's cheeks warmed, her heart pounding as she felt the warmth of the cheerleader's body on her back, the girl's arms wrapping around her, grabbing her wrists, positioning them correctly. "Like this!"

"O-Oh," Matti stammered. "R-Right."

It didn't feel that much different from what she'd been doing, but it seemed like this stuff was all about precision, so she assumed that was why Valerie had decided she'd needed the help. At least, she assumed that until Valerie leaned down, whispering in Matti's ear, "Pee your pants."

"Wh-What?!" Matti squealed, her blushed darkening as it felt like the entire rest of the cheerleading squad looked at her.

"What's going on?" Kelsey asked with a sigh, giving Matti a dirty look.

Matti almost wanted to tell her, to let her know that Val was being mean to her, so that her big sister could deal with her bully the way she had when they were younger, but that would leave Valerie open to show her that video, and Matti knew she couldn't let that happen.

"I'm just helping her with the move," Valerie said innocently. "She's having a little trouble, but I think she's getting there."

"Then what are you freaking out about?" Kelsey glared at Matti, who didn't have a good answer for that. "You should be thanking her! She's the one who has a game coming up, and she's using her time to help you!"

"W-Well, I didn't..." Matti protested.

"Come on, Matti," Kelsey rolled her eyes. "Can you please not embarrass me by throwing a tantrum in the middle of practice?"

"I'm not!" Matti huffed, stomping her foot, the other cheerleaders, who had giggled at Kelsey's request, laughing harder at Matti's reaction.

"Don't worry," Valerie smirked. "I've done plenty of babysitting, so I know how to deal with tantrums. I've always wanted a baby sister." Matti blushed, feeling very much like a helpless younger sister as she stood there, Valerie's hands still clasped around her wrists, holding her in place, giving her no hope for escape from the stares of the rest of the squad.

"Well, you can have her," Kelsey shrugged. "She's more trouble than she's worth most of the time." She tilted her head down towards Matti. "Can you just do what she says without raising a fuss, please? You're disrupting the whole practice!"

"Yeah, Matti," Valerie grinned. "Be a good girl."

Matti squirmed, knowing that Kelsey couldn't have known what Valerie had whispered to her, but still flustered at the thought of her sister having, unintentionally or not, reinforced the order for her to wet herself, right in the middle of practice. She felt a slight tingle in her bladder, but she knew that was never going to happen, not with all these eyes on her. Just the idea of it, though, of letting go, letting them all see the wet spot form on the crotch of her gym shorts, the urine quickly soaking through and trickling down her legs, making a puddle beneath her, showing them how much of a baby sister she was, made her a little weak in the knees. She was grateful Valerie was still holding onto her so they wouldn't buckle on her.

"Seriously," Kelsey sighed. "All right, let's get back to work!"

Matti, of course, didn't pee her pants, and she hoped that Valerie would somehow forget about it by the end of practice. Instead, she cornered Matti in the locker room afterwards. "I get the feeling you're not taking this seriously," she hissed. "I guess I'm going to have to show you how serious I am."

Valerie found Matti before the next practice, grabbing her by the elbow and dragging her to one of the tiny bathroom stalls by the showers at the back of the locker room, barely big enough for both of them. "Here," Valerie told her. "I got you a present."

She shoved it into Matti's hand, Matti's stomach lurching as soon as she felt it, and heard the soft rustling, though she had to glance down to confirm it, hardly able to believe what was happening. "Th-This is..!" she gasped, before quieting herself to a whisper, not wanting anyone to overhear. "This is a Pull-Up!"

"Yes, it is," Valerie ruffled Matti's already messy hair. "What a clever girl! And you are going to put it on, and bring me your panties to hold onto until practice is over."

"B-But I don't need them!" Matti hissed, her pulse quickening. The Pull-Ups were nothing compared to the diapers she'd worn on her last little adventure, but, somehow, this felt worse, knowing that she was going to be in it in front of her sister, and the rest of the cheerleaders. Her shorts and t-shirt with baggy enough to hide them, no problem, but what if her shorts slid down, somehow, and showed off the childish designs, the weak, sad attempts at making the training pants appear to be normal underwear that wouldn't fool anyone over the age of three, if even them?

"That's right," Valerie nodded. "You don't need those big girl panties. And you won't be getting them back if you keep being difficult."

With that, she stepped out of the stall, closing the door behind her, Matti having to scramble to grab it and lock it before it could swing open again and expose her, and what she was holding in her hands. She blushed, staring down at the Pull-Up. It might not have felt so bad if it wasn't so girly, covered in flowers, with some Disney princess she didn't even recognize, since she hadn't paid any attention to that sort of thing in a long time, on the front.

But nobody was going to see, she told herself. Nobody had to know except her and Valerie. It wasn't much of a comfort as she stripped out of her shorts and undies and pulled the trainers up her legs, but once she had them covered so she didn't have to look at the design, she had to admit she didn't mind them so much. The thought of wearing them to practice, where her sister was going to be, was nerve-wracking, but also a little thrilling, and being in any kind of padding again was nice.

Even handing over her underwear, balled up and hidden in her hands as best she could as she shuffled through the locker room, was exciting, knowing she was leaving their fate entirely up to Valerie, that there was a chance she'd never see them again. She had plenty of other pairs in her room, obviously, but in that moment, standing before the bigger girl, wearing a Pull-Up and voluntarily surrendering her big girl undies, it was easy to pretend that wasn't the case, that, if she played her cards wrong, she could be stuck in trainers for good.

So she did have a little extra incentive when, this time around, Valerie found the opportunity to whisper to her, "Pee yourself." And she did think about it. The Pull-Ups would probably hold it, and she was at the back of the gym, as usual, so as long as she kept quiet, there was a chance nobody would see her.

But there was also a chance somebody could turn around at any moment and spot her. And, as closely as her sister was watching her, making sure she was trying, and not just sulking and watching quietly, there was a decent chance it would be her. It had, of course, been a very long time since Kelsey had seen her wet her pants, but who knew what memories the sight of it might dredge back up? Not to mention that Kelsey had done some babysitting, including for their cousin, Brooke, who wasn't all that long out of trainers herself. Or what if the Pull-Ups weren't absorbent enough, and she leaked after all?!

Thankfully, the padding meant that there was no real way for Valerie to know if she'd obeyed or not without paying attention only to her, instead of practice, unless she had intended them to leak. Matti never fully forgot about the task she'd been given, but she was able to push it aside for the most part as she attempted to copy the moves the other girls were doing, and keep from getting distracted by the feeling of the Pull-Up rustling between her thighs, occasionally rubbing against her in just the right way to remind her of her time in Ms. Emily's office.

"You stay right here," Valerie demanded when practice was over, sitting Matti down on a bench. "I'll deal with you after I'm finished changing."

In a way, it was just another show of her dominance, forcing Matti to wait, but at the same time, it was also a relief, knowing Valerie wasn't going to check her right in front of everyone else as they gathered up their things from their lockers, a few going to the showers there, others opting to go back to their dorms to clean up instead.

It gave her a little time on her own, too, with everyone else busy with their own thing, not paying attention to her. She was even sitting down, which was a big help. She closed her eyes, pretending she was sitting on a toilet, rather than a locker room bench, and let go, feeling the padding grow warm and damp beneath her, swelling slightly.

"Is everything all right?"

Matti's eyes popped open, her feet swinging nervously on the bench as she looked up at Kelsey, her whole face turning red as she realized she'd just done exactly what she'd been afraid of doing during practice. Hopefully, her sister hadn't seen most of it, but there was no way for her to know now. "Y-Yeah," she nodded quickly. "I-I was just thinking over the new stuff I learned today."

"Hmm," Kelsey said skeptically. "Well, it did seem like you were paying more attention. I think having Valerie working with you has really helped."

Matti squirmed, swallowing as she felt her Pull-Up squish beneath her. "Y-Yeah," she answered weakly. "I-I think so..."

As Kelsey walked away, she cursed herself silently. Why hadn't she said no?! Maybe then Kelsey would have made Valerie leave her alone! Then again, would Valerie really have accepted that? Or would it have made her more angry? It was hard to tell. Matti tried to tell herself that was her reasoning, that it wasn't just her excitement at getting to wear training panties, despite, or maybe partially because of, the embarrassing circumstances. She honestly couldn't say for sure, though, one way or the other.

Valerie didn't emerge from the showers until everyone else was gone, whether that was by design, or just how long she normally took. She wasted no time marching up to Matti and demanding, "Shorts down."

Matti hopped off the bench and did as she was told, heart pounding as she exposed her soggy Pull-Ups, feeling very much like a naughty little girl as Valerie knelt down and gave them a squeeze, as if the faded flowers didn't already show her that Matti had, indeed, peed her pants today.

"Really, Matti?" Valerie's eyes narrowed. Matti frowned. This was not the reaction she'd expected. "This is still warm," Valerie told her. "You just did this, didn't you?"

Matti blushed, not knowing what to say. Valerie glowered. "Bring me your bag," she ordered. Matti bent down to pull her shorts back up, but Valerie grabbed them first. "Step out," she snapped.

"B-But what if somebody comes in?" Matti gulped.

"Then they'll see your wet Pull-Ups," Valerie told her simply. "You'd better get your bag before that happens, I guess."

Matti stepped out of her shorts, hurrying over to her locker quickly and getting out her bag, returning to Valerie with it. "You have your laptop in there, don't you?" Matti nodded. "Get it out and log in. Do you have any assignments due soon?"

Matti squirmed, staring up at Valerie anxiously. "Don't you try to lie to me," Valerie scowled. "You already tried to outsmart me once, you little brat, and you're about to see what that gets you."

"Y-Yeah," Matti admitted. "I have a paper due tomorrow."

"Perfect," Valerie nodded. "Log into the school system." Matti didn't like typing in her password with Valerie watching her like a hawk, but there wasn't much she could do about it. As soon as she had, Valerie took the computer from her, turning it around to poke around. "Look at these grades," the girl shook her head. "These are much too high for a little diaper bimbo like you. But don't worry, sweetie, we're going to work on that."

Matti gulped. Valerie wasn't really going to go that far, was she? She wouldn't do anything that actually affected Matti's grades! "Here we go!" Valerie exclaimed. "This looks like the paper! What a good girl, having it ready to turn in already! Except, it isn't quite ready, is it?" She clicked a few buttons, then set the computer back on Matti's lap, sitting down next to her on the bench for a moment before scooping her up onto her lap.

"This is all very nice," she nodded, scrolling through the paper. "Oh, but I don't like that part." She pointed to a paragraph on the screen. "Delete that for me, will you?"

Matti felt so tiny, so helpless, sitting there on Valerie's lap in her t-shirt and trainers, the girl's arms wrapped around her again, holding her in place. "I-I can't do that," she shook her head. "I-If I do that, then this next section won't make any sense!"

"Matti," Valerie told her sternly, "I could make you walk out of this locker room right now. You'd have to walk to your dorm just like this, with your soggy little Pull-Up on full display. Is that what you want? I mean, I know you like to do that at night, when nobody's around, but I can promise you, there are still going to be plenty of people out and about now."

Matti swallowed. She didn't just feel helpless here, she was helpless, totally at Valerie's mercy. Reluctantly, she scrolled her cursor up to the paragraph Valerie had indicated, triple clicking to select it all, and, after a tiny bit of hesitation, hit backspace and watched it disappear.

"Good girl," Valerie praised. "Now, I don't think this is how that word is spelled, do you? Why don't you try again?"

Valerie took her through the entire paper, taking out huge chunks of it, making her misspell things, completely mangling all of the work she'd done, until, finally, satisfied, Valerie told her, "I think that's ready to be resubmitted."

"B-But..." Matti whined, fidgeting on Valerie's lap. "I-I'm gonna be lucky to get a C on this!"

"Yes," Valerie nodded. "I know that's even a little high, but like I said, we'll work on it."

"I can't get a C!" Matti protested.

"You're going to what you got on this after your professor sees it," Valerie informed her. "And if you get anything above that, then you're in serious trouble, young lady. Now hit submit."

She could have pushed Matti's hand aside and done it herself, just like she could have done with any of the changes she'd requested, but there was something extra mean about forcing Matti to do it. Matti sighed, feeling trapped as she moved the cursor up to the button and hit it, getting only a pat on the head as a reward for tanking her grade in that class.

"I hope you're going to do as you're told from now on," Valerie said, lifting Matti down onto the floor. "I suppose you've earned your shorts back."

She handed them over, and Matti started to pull them on before remembering something else. "Wh-What about my underwear?"

"I don't like little girls who think they're smarter than me," Valerie told her. "I'm keeping them. Well, not keeping them, I don't want those nasty little things, but I'll be throwing them away."

"You can't throw them away!" Matti pouted. "They're mine!"

"Do you want me to do the same with your shorts?" Valerie raised an eyebrow, and all Matti could do was shake her head meekly. "I didn't think so."

Matti had worn the Pull-Ups for as long as she dared, despite her protests, changing out of them only when she went to have dinner in the cafeteria, afraid someone might smell her if she kept them on. She'd spent much of the rest of the night debating whether she should risk Valerie's wrath by trying to reconstruct her paper in its proper form before finally realizing she was too much of a chicken for that.

She couldn't face the professor for that class the next day, afraid they'd already gotten a glimpse at what she'd submitted, even though she knew she was already pushing the limit on absences from that class, and risking a lower grade from that as well. At least that would make Valerie happy, she thought sulkily.

The grades weren't up by rehearsal time, and, fortunately, Valerie didn't ask to see them. She didn't even make Matti put on another Pull-Up, though Matti didn't know if she was glad for that or not. She left Matti alone completely, in fact, making Matti wonder if she was satisfied now.

And then, practice started. "I have a little announcement," Valerie declared. "We've all seen Mathilda here lately," she gestured to Matti, who forced a smile despite being called by her full name. "And she's still learning, but she's doing her best, and it really seems like she wants to join us, so I made her a present."

She held it up, grinning. It was a copy of the other cheerleaders' uniforms, red with stripes of white and black around the edges. The top looked like two strips of cloth criss-crossed across the chest more than anything, far shorter and skimpier than anything Matti would normally wear, and the skirt wasn't much better. The worst part, however, was what was written on the front.

"Isn't that cute?" Valerie giggled, making sure everybody saw those four humiliating letters. "Because she's a baby cheerleader, who isn't really on the squad yet."

"That's so sweet of you," Kelsey smiled. "I'm sorry she's so rude that she hasn't said thank you yet." She gave Matti a pointed look. "Come on, Matti."

Numbly, Matti shuffled forward, through the other cheerleaders, hardly able to believe this was happening. She'd assumed she'd have until next year, when the try-outs happened, before there was any possibility of her having to wear one of these uniforms, yet here one of them was, made especially for her. She was never going to live this down if any of her friends saw her in this! "Th-Thank you," she mumbled.

"Go on," Kelsey urged. "Go put it on while we get started." Matti wrinkled her nose, looking at the other cheerleaders, seeing how much skin she was going to be showing in this thing.

"Actually," Valerie spoke up, "why don't I go help her? You know, just to make sure she gets all her straps straight and everything?"

"Sure," Kelsey shrugged. "Knowing her, she probably needs it."

Valerie grinned down at Matti, taking her by the hand and leading her back to the locker room, snatching the uniform out of her hands when they arrived. "Strip," she ordered, and, when Matti didn't start moving immediately, she began to undress her, tossing her baggy, comfortable clothes into a pile on the nearest bench. "Wow," she giggled when she got Matti's shirt off. "Maybe I'm going to have to buy you some padded bras, too, to give the guys something to look at when you're in your uniform."

Self-consciously, Matti crossed her arms over her chest. "N-No guys are going to see me in it," she reminded Valerie, and herself, to make her feel slightly better about the situation. "N-Not until next year, IF I get onto the squad."

"We'll see," Valerie smirked, pulling Matti's hands upwards so she could slide the top down over them. "Of course, this isn't the most important part of your uniform."

She slid Matti's shorts and underwear down, putting them aside as she turned to her locker and produced something else, something that, thankfully, she hadn't shown the rest of the squad. "N-No!" Matti stomped her foot, her head spinning. "I-I can't wear a diaper to practice! Everyone will see!" That wasn't the worst part, though, was it? "M-My sister will see!"

"But it's going to be so cute," Valerie grinned, snapping the diaper open, Matti nibbling her bottom lip as she heard that familiar crinkle, and saw Valerie lay the diaper out on the floor, open and waiting for her. "They'll think it's a part of your little uniform, Baby." She ran her hand over the printing on Matti's chest to emphasize that last word. Maybe that was true, Matti thought. Maybe they'd think it was a little joke, to go with what Valerie had chosen to put on her uniform. Of course, it had a very different meaning to Matti, and Valerie. "Well," Valerie smirked playfully, "until you wet it, anyway. Then they'll all know you really need it."

Matti gasped, turning bright red. "I-I'm not going to do that!"

"Oh, yes, you are," Valerie told her. Matti couldn't help but wonder what made her so sure, the tone of the other girl's voice making her scared, and, if she was being totally honest, a little turned on. "Now, lie down."

"I-Is the skirt even long enough to cover it?" Matti whimpered, looking at Valerie's to try to compare, though it was hard to even imagine the larger, more intimidating, girl wearing a diaper.

"It will probably be fine," Valerie shrugged, giving the diaper a pat.

"Val..." Matti pouted, ending in a squeak as the cheerleader grabbed her, pulling her down onto the diaper with a thud, her backside protected from the impact by the soft padding. The babysitting experience Valerie had claimed to have became quite obvious now as she pushed Matti onto her back, quickly and expertly taping her snugly into the diaper, no amount of squirming or protesting from Matti able to stop her.

And just like that, Matti was back in diapers, wearing a cheerleading uniform that seemed to invite everyone to look for them, and confirming for them what that extra padding around her bottom really was. As exciting as being back in diapers was for Matti, it was also terrifying, knowing she was back in the real world now, with real consequences.

"Oh, my God," Valerie snickered, snapping Matti out of her reverie with the sound of her phone's camera shutter. Matti blushed, attempting, too late, to cover her diaper with her hands, rather than giving the girl more ammunition to blackmail her with. "You look even cuter up close! Why don't we go show everyone else?"

She took Matti by the hand, and, to Matti's horror, she gave it a tug, pulling her towards the gym. "Valerie!" Matti squealed, heart thumping as she struggled to make the girl stop, and realized she couldn't, that, if Valerie wanted, she could parade her out in front of the other cheerleaders this way. "N-No! Pl-Please, give me my skirt!"

"But you didn't think it would be long enough," Valerie shrugged nonchalantly. "So why bother?"

"I-I'll try it!" Matti said. That was far better than the alternative!

"Will you?" Valerie arched an eyebrow. "I don't know. I like the way you look now, so maybe I'll just keep the skirt."

"Valerie, no!" Matti shook her head. "Please! I'll do anything!"

Valerie grinned, Matti's stomach churning at the girl's expression. She'd just given her exactly what she wanted. "Well, in that case," Valerie shrugged, leading Matti back to her locker. "I might have a little something more for you." She dug into her bag, producing a large baby bottle filled with milk. "Do you want a little snack, Matti?"

Matti wrinkled her nose. Among plenty of other foods, milk was something she was not particularly fond of. But if that was what she had to do to get her skirt, she could endure it. "O-Okay," she nodded reluctantly.

"Good," Valerie smiled. "Because I made this special for you."

Matti shivered as she heard the tone in Valerie's voice. What did that mean?! Had she done something to the milk?! She could have hidden quite a bit in there, and Matti wouldn't be able to tell from the outside! She could be trying to drug Matti with diuretics, or even laxatives, or potentially something far worse, if she wanted! Matti gulped, recognizing how much she was at the cheerleader's mercy now. "O-Okay," she repeated, more quietly, reaching for the bottle.

"What are you doing?" Valerie asked. "You're a baby, aren't you? Your uniform says it, and so do your diapers. And babies don't stand up, do they?"

"N-No," Matti shook her head, lowering herself to her knees, making Valerie tower above her even more. Her cheeks darkened as she looked up at the girl, catching a glimpse of her skimpy panties beneath her skirt before she could look away, so very different from what Matti was going to have under hers, if she was allowed to have her skirt at all.

She reached for the bottle again, Valerie waiting until the last moment to pull it away. Matti almost lost her balance, having to reach out for the nearest thing to keep from falling. Unfortunately, that was Valerie's leg, making it look like she was clinging to her for comfort or something.

"Babies can't hold their bottles on their own, either," Valerie told her. "You just leave that to me. Open wide!"

Matti bit her bottom lip, looking up at Valerie, then, slowly, opened up her mouth, readying it for the bottle's nipple, leaning forward slightly. "Hold on," Valerie said. "I think I know a better place for this."

She moved the bottle over, from her side to right in front of her crotch, holding it out in a way that felt so wrong, so obscene. "Go on, Matti," Valerie urged. "Get your milkies."

Matti whimpered, eyes darting towards the locker room door, imagining someone walking in on her, on her knees in her diaper and cheerleader top, lips wrapped around the bottle's nipple as it dangled between Valerie's legs, looking very much like she was doing something else, something she had definitely never done. "Do you want your skirt or not?" Valerie asked when she didn't move.

"Y-Yes, ma'am," Matti mumbled, slowly moving her mouth to the tip of the nipple, and starting to suck. It had been so long since she'd had milk, it was hard to judge for sure if it tasted normal or not, which almost made it worse. She could be dosing herself with something that was going to make her use her diapers before practice was over, and she'd never even know! As utterly humiliating as it all was, she couldn't deny the warmth building between her legs as she did it, not knowing what this was going to do to her, whether someone was going to walk in on them and find her this way.

"You can do better than that!" Valerie scolded. "Come on, Matti! Do you want to be in here all day? Harder!" Matti gasped in surprise as Valerie's free hand moved to the back of her head, pushing it in closer to the bottle, forcing more of the nipple into her mouth, more of the milk gushing out in response, Matti blushing as some of it dribbled out from the corners of her mouth.

Finally, Matti had drained the bottle, and Valerie helped her step into her skirt, smirking as she pulled it up over Matti's diaper. "We have a lot of work to do," she said. "But don't worry, "I'll make sure you do it."

The skirt did cover her diaper, but only just, providing a very small comfort for what she'd done to get it. "Wh-What if I have to kick?" she asked nervously, remembering only then that there had always been another part of Kelsey's cheerleading uniforms that she hadn't seen with this one. "Sh-Shouldn't I have bloomers?"

"Look at you!" Valerie chuckled. "A cheerleading expert now, are you?"

"N-No," Matti shook her head. "B-But if I move, like, at all, everyone's going to see my diaper!"

"Well, then I guess you'd better hope you're right about how stupid cheerleaders are," Valerie sneered.

"Valerie, please!" Matti fell back down to her knees, clinging to the girl's leg again. "I-I know they aren't, so please don't make me go out there like this!"

"I guess if you want them that badly," Valerie said, as if she were surprised by that, "I have something else you can suck on."

Matti stared up at her, again catching a glimpse under Valerie's skirt, getting a reminder that she wasn't wearing bloomers, either. That had to be on purpose, didn't it? Matti's heart began to thump, her palms sweating slightly. Was Valerie really going to make her do that?! Matti wasn't really into girls, but it was hard to deny how pretty Valerie was, despite how mean she had been to Matti. And, as embarrassingly hot as what Valerie had made her pretend to do with the bottle was, this pushed all those same buttons, and even harder, because it was for real.

"I-I can try," she heard herself say, reaching up to push Valerie's skirt aside.

"No, not that, you perv," Valerie sniffed, as if she hadn't been just standing there for so long, giving Matti no other indication of what she could mean, to let her mind wander to that. "I don't trust you to do that... Yet." Matti squirmed at the last word, just the way she was certain Valerie had wanted her to. "I just meant I had another bottle. Let's see if you can do a little better this time."

Whether she did or not was hard for Matti to judge, though she did finish it up a bit quicker. By the time she stumbled to her feet, she could see why Valerie had seemed so sure she would be wetting herself this time, as all of that milk sloshed around inside of her. Even without anything being added to it, those two bottles of milk were plenty to ensure that she would have a very hard time making it all the way through practice without needing to go. Thankfully, the bloomers that Valerie gave her to put on, while she slid her own up as well, were big enough to keep her diaper covered, and hide any evidence there might be of any accident. How well they'd fool anyone who was keeping an eye on her, she didn't know, but it was far better than nothing.

"I don't think I have to tell you what I want you to do during practice, do I?" Valerie asked as, finally, she took Matti back to the gym.

"N-No, ma'am," Matti shook her head. Already, she wasn't sure she'd have a choice about it anyway. She blushed bright red as the whole squad clapped for her when they reappeared, nervously adjusting her skirt until she forced herself to stop, worried she'd tug on it too much and flash the waistband of her diaper. After that, luckily, she was able to go back to the back of the gym, on her own, again, most of the other girls ignoring her, and hopefully not noticing anything strange about her movements, or hearing the slight crinkle she made, or spotting the shudder of delight that came when she moved just right, and her diaper rubbed against her in a way that made her feel so very naughty, especially after, inevitably, she had to wet herself, finding a moment when the squad was taking a break, and she could sit on the bleachers.

She was certain she'd gotten away with it until they all headed back to the locker room, Matti suspecting she'd be waiting on the bench for Valerie again, so she could decide what to do with her. This time, at least, there was no denying that she'd peed her pants long before practice was over, thanks to how cool and clammy her diaper was, so Valerie would have no reason not to let her have her panties back. Not that she necessarily needed one, if she wanted to torment Matti further.

"Hey," Kelsey stopped her before she could step through the door.

"Y-Yeah?" Matti swallowed, staring nervously down at her feet as she faced her sister, her soggy diaper suddenly feeling so much more obvious, despite everything. Did she know? Had she known all along?!

"Valerie is really taking you under her wing," Kelsey told her. "She doesn't have to do that, you know."

"I-I know," Matti nodded, wondering if Kelsey would have quite as high an opinion of what Valerie was doing if she knew the truth.

"Then you'd better not make me look bad by being an ungrateful little brat," Kelsey warned her. "I want you to do whatever she says, and be nice to her."

Matti's cheeks burned, bottom wiggling in her wet diaper, reminding her of everything that Valerie had told her to do just that day. "Y-Yes, ma'am," she said quietly.

"Did you just call me ma'am?" Kelsey giggled, Matti realizing only then that she had, having forgotten for a moment that she was talking to her sister, and not Valerie.

"Don't get used to it," Matti teased, sticking her tongue out. "It just slipped out."

Kelsey smiled, something Matti was not used to having directed at her from her sister, who was normally scowling, or rolling her eyes, at her instead. "See? I knew getting involved in cheerleading would do you some good!"

"It's certainly... doing something," Matti blushed. She wasn't sure if she would call it good or not, but she certainly had a feeling that things were never going to be quite the same for her after all this. Not if Valerie continued to get her way with her, and, as pleased as Kelsey seemed to be with Valerie 'helping' Matti out, Matti suspected that wasn't going to be ending anytime soon.
