[ABDL, Diaper Use, Soiling]

"Ehehehehe... You really can't hold it, Poopy Baby Yukikaze? No wonder you're wearing such a thick diaper!"

"Y-You're one to talk, Shigure..!"

While the gradual loss of continence had swept through the base, some were more affected by the Infitting formula than others. Especially if they had been personally exposed to the formula before it reached the base, as was the case for Yukikaze. The white-haired Destroyer had been part of the exchange program that led her to visit Maidens' Dream, and she was given the full course by the inhabitants. Much to her continued displeasure.

It was why she had earned her reputation as a Poopy Baby around the base. Even for the ones that had succumbed to the Infitting formula, they were not able to soil their diapers nearly as much as she had. And considering the way that she almost always forced it to drag against the floor from how small her body was combined with how thick her diapers were, it was impossible for people not to notice and whisper and chat about it.

But it was something that she had come to try and accept. Try being the key word, because not everyone would try and just leave her alone because of how stinky she had gotten. No, there was one specific other individual who just kept on teasing her no matter how stinky she had gotten. And that was her fellow Destroyer, Shigure. That black-haired kitty kept on pestering her, no matter the current state of her diapers. Whether they were stuffed full of poopy or they were as dry as they could possibly be.

And she just happened to stop by while she was busy trying to keep it all in this time. Because she knew that her dear Yukikaze wouldn't be able to keep it inside. Which was why the black-haired kitty was currently grinning from ear to ear, despite the fact that her own diaper was out in the open. Hers was clean, so she thought that she was immune to teasing...

"Oooo, you look like you're right on the verge of bursting again, Poopy Baby Yukikaze." Shigure grinned, as she put a hand right on that extra puffy pamper. "I bet you're going to fill it as soon as I take my eyes off you. You could never hold it in, ehehehe..." Shigure grinned, all while rubbing that diaper and pressing her hands up against the padding, forcing it to push against her fellow Destroyer's most private spots...

Yukikaze wanted to just straight up ram her padded bottom right into the black-haired nuisance's face for this kind of teasing. But her stomach was playing foul. Since she was so far along the Infitting process, her control was null and void. But that didn't mean that she couldn't feel excruciating pain. God, why did she have to have such a sensitive stomach? It just had to throw a fit whenever she started getting close to the part where she had to fill her diaper, and then she would have to squat down and lose all semblance of dignity...

*FRRRRRRRRRT*

Indeed, the white-haired kitty was forced to squat down just as the thought crossed her mind. And the fart that slipped out of her rear, adding an extra foul scent to the air around her, served as a very brief warning before the back of her diaper quickly turned soggy and brown as an untold amount of liquid poopy poured right in. At least filling it meant that she could catch her breath, since all the pain started to fade away. If it stuck around, then it would just make her experience even worse than it already was.

"That's a good Poopy Baby! Maybe we should go visit the Admiral, I'm sure that she'd love to see you fill that diaper!" Shigure wasn't going to let her rest and feel like she could endure the teasing, however. She was more than happy to just push that hand into the dirty diaper and tease her fellow Destroyer more, to see that red shade force its way across Yukikaze's face-

*Hissssss...*

But in her haste, the black-haired kitty ended up going too far. And in her excitement, the contents of her bladder just poured on out. The front of her diaper quickly turned just as soggy as Yukikaze's, while the color was more of a foul yellow rather than a stinky brown. Though that didn't mean that she was enjoying the experience or anything. In fact...

Shigure's confident teasing vanished as she muttered and mumbled and tried to back away as she felt the gross sensation of the extra wet diaper rubbing up against her. She really didn't like the way it warmed her crotch, much less the way that it just squished up against her thighs and sounded all sorts of soggy. It was the worst. The very worst. She hated it, oh she hated it...

Yukikaze took a deep breath as she finally had some peace and quiet. And, honestly, seeing Shigure lose control like that and lose a lot of her confidence in the process... It was a relief. It meant that she was going to end up just as broken as her. But how long would it take to make her a Baby like her... Well, only time could tell. Especially since she was more of a Pissy Baby instead of a Poopy Baby...

Though, a thought started to drift through the white-haired kitty's mind. Perhaps she could speed things up a bit, and still get the chance to punish Shigure for what she did to her each and every day? Sure, it meant that she would have a direct hand in another girl being reduced to her most infantile state, much like she had been... But at this point, her ability to judge things morally had already been impaired due to the continued exposure to the Infitting formula...

"O-Okay. Okay. I'm sorry for teasing you so much, Yukikaze..." Shigure took a deep breath, all while trying her best not to squeeze her legs together. She didn't want to acknowledge that she had peed herself. She just wanted to deal with the current problem and be done with. "How about we trade? I'll change you out of that stinky diaper, and you help dry me off and we call us even? I'll even stop teasing you for a few days! That's a good trade, right? Right?"

Yukikaze would disagree if she didn't have a plan in mind. So instead she nodded and softly smiled. "Glad to see you know when to quit..." She muttered, before motioning for her to follow. She needed one of the specific changing stations, because otherwise she'd have to waddle around in one of the smaller diapers. And after the last time they ended up leaking due to the size of her messes, she didn't want to chance it.

Shigure was not satisfied with the sensation of the diaper rubbing up against her crotch, nor with the way it squished in such a wet manner. But at least the trip to the changing table was short and swift. It felt a lot longer due to the sensations that were rubbing up against her, but at least... At least she wouldn't have to worry that much...

Changing Yukikaze was easy. Due to the size of the diapers, the tapes were both secure and easy to remove. A paradox, but a relief at the same time. Her messes were far too large and too frequent, so this kind of setup was a relief both to the white-haired kitty and the ones that had to change her. That, and due to the liquid nature of most of her messes, she didn't exactly need to get that much wiped away because not a lot of it managed to stick to her private areas.

Once Yukikaze was snugly padded up once again, it was Shigure's turn. And the black-haired kitty did what she thought was right. She trusted that the white-haired kitty wouldn't mess with her like she had, and carefully just laid on the table with her legs lifted into the air to make it easier to handle her diaper.

"You know, if you were a Poopy Baby like me, you wouldn't have to deal with this kind of embarrassment." Yukikaze mused as she carefully removed Shigure's diaper, balling it up and putting it into the same pail that had her own stinky diaper. All while she reached for the supplies that she needed to help clean up her fellow Destroyer...

Shigure whimpered a little. "I don't wanna be one. I like diapers, but I don't like using them. They're cozy, they're not supposed to be stinky or sticky or anything!" She cried out, almost like a Baby would as she expressed her distaste. She was definitely on her way to being a proper Baby, she just needed that little push to end up as bad as the rest that had already given in.

And it was because Shigure had already fallen so far that she didn't anticipate something getting stuffed into her butt. She could feel a rubber tip pushed in between the rim of her hole, and she immediately started to struggle. "W-What are you doing?!" She cried out, trying to get a good look at what had just happened...

Right before she felt a wet sensation traveling right up her rear. A very thick and wet sensation. As if she was being stuffed full of... M-Milk. Oh no. No no no. She wasn't... Why would she...

Yukikaze grinned a little as Shigure finally realized what had happened. "What's the matter?" She chimed, as she kept squeezing her hand down on the bottle that was currently stuffed into her fellow Destroyer's ass. "It's just a bit of Infitting milk. You've had it before, you can handle drinking it from your butt. I've tried it, don't worry." She giggled, all while slowly grabbing one of the wipes that were also prepared for changes like these.

"S-Stop! I don't wanna-" Shigure tried to cry out, only to let out a very rough moan as she suddenly felt a scraping-like sensation up against her pussy. It wasn't painful, but it was definitely not something she was prepared for. S-Sure, she was dirty down there, but that didn't mean that she wanted to get her pussy rubbed...

And yet that's exactly what Yukikaze did. She needed to get the black-haired kitty's pussy nice and clean, and that meant that she had to wipe away all the pee. But she didn't need to be gentle. Especially to a girl that had been such a bitch to her. She was going to make the experience as intense and as aggravating as possible, especially as that rough cloth just kept on going up and down...

It wasn't just one cloth either. Because there's no way that she could clean her with just one wipe. Once Yukikaze had dirtied up the first wipe, then she used another. And another. And as many as it would take, all while repeating those same rough motions to ensure that she wouldn't escape the pleasure that came with how rough it was...

Shigure was trying to endure the experience. But the further the milk poured into her, the more her stomach started to cramp. It was being absorbed into her, even though it hadn't reached that far inside her. And the pleasure that was coming from the rough wiping just made it harder to try and fight back.

The only idea that came to mind was to try and push it all back out. So she wouldn't be permanently incontinent. Sure, she'd have to deal with being as poopy as some of the other girls at the base, but at least she would still be able to recover!

Unfortunately, pushing wasn't an option. Sure, she could get a few *frrrrts* to push out from the gap between the bottle and the hole itself, but that didn't mean she could get the liquid to pour out. The gap was just too tight, and it just... It just made the stomach cramps even worse. She hated it.

And it's not like her attempt went unnoticed either. "Trying to poop on me, Shigure? You're a bigger Baby than I thought. And a natural Poopy Baby too!" Yukikaze grinned. It had been a long time since she got to turn things back on Shigure, and she was going to make sure that she savored every moment of it...

Shigure couldn't reply, and she definitely couldn't stop the other Destroyer from applying copious amounts of cream and powder. All of that was meant to make sure that she didn't get a rash, and it felt... It felt different from the wipe being rubbed up against her, but it didn't feel good in any sense of the word.

"Better get used to this, Shigure. You're not getting a change for a long time." Yukikaze's wicked grin was growing. Ah, is this what she felt when she was bullying her over being a Poopy Baby? Maybe she should try it more often... The role of being a Baby Bully was making her feel all sorts of excited...

As soon as Shigure's butt and crotch was as covered in cream and powder as it could be, the bottle was fully emptied and the diaper was quickly fastened around the black-haired kitty's waist. There's no way that Shigure was going to be allowed to get a single drop of that milk to slide out of her. Not while she was this close to being rendered a complete Poopy Baby for the rest of her life.

Shigure certainly tried to push. But the moment that the diaper came on, the pressure in her stomach just grew. And she quickly realized that if she started to push, then she wouldn't be able to hold it. She'd fill her diaper, and then... N-No, she had to get away. She had to get away..!

The black-haired kitty got off the changing table as she quickly ran towards the hallway that would lead her towards one of the toilets. Sure, the toilets were probably blocked, but she at least making it there would make it seem like she was trying to still be a big girl. "I don't want to be a Poopy Baby! I don't want-"

She didn't get far. Partly because of the effects of the milk making her stomach hurt even more... And partly because Yukikaze grabbed ahold of her collar and forced her to fall right down on all fours, the kitty's reflexes ensured she wouldn't hit the ground. But even then, with her diaper stuck up into the air and her face this close to the ground..!

The shock of everything. The pleasure that was still pouring through her, the speed at which she fell, the pain in her tummy, and the sheer desperation... It melded together and released in one big brassy *BRAAAAAAAAAAAAAAAAAAAAP* pouring forth from her cheeks, the gas heralding the complete destruction of her bowels, all while tears started to pour down her cheeks...

Shigure couldn't stop it once it had started. The poopy just rushed into the padding. Her diaper was ill-equipped to the rush too, to the point where it almost seemed like parts of her extra runny poopy would pour out through the leg holes and down her thighs. But against all odds, it managed to stay in there. While turning the entire thing brown and making it clear that she had messed it to its absolute limits.

She hated it. She hated the sensation of her mess rubbing up against her. She hated the way that her diaper sagged and weighed her down. She hated the smell. She hated everything about it. And she couldn't do anything except sob, because she had absolutely no control left. She couldn't close her hole... She couldn't stop it from flowing out. Just like she couldn't stop her tears.

"Ehehe..." Yukikaze giggled, throwing that teasing right back in the black-haired kitty's face as she pushed her hand up against that extra stinky and extra brown diaper. "I know it feels nice to break, I remember the first time I filled my diaper this much..." She mused, pressing it further up against the Poopy Baby's crotch to ensure she couldn't escape the wet and sticky sensation. "But you're in a class of your own, Shigure. You smell way worse than I do. Maybe we should ask the Admiral if she'll change your class. I'm sure everyone'll love to call you a Poopy Baby..."

Shigure sobbed as she heard all of that teasing. It made all of this feel even worse. It made her realize just how badly she had been treating Yukikaze. Because she was right. She was absolutely right. Her smell was horrendous. The way that it rubbed up against her was making her feel sick. But... B-but most importantly... S-She was right, it actually felt really good. And that was the worst part of it all. The knowledge that she was getting turned on by her own mess...

"Y-You're right..." Shigure sniffled as she slowly looked up at Yukikaze, moaning in such a pitiful way as that hand pressed into her diaper once again. "I-I'm the stinkiest and poopiest baby here... T-The real Poopy Baby..." She muttered, as she very carefully lowered her legs... And let that diaper squish against the floor, making her cry out in a mixture of shame and delight. "Y-You're so right... I-I hate it, b-but..."

Yukikaze giggled. And then she kneeled down, letting her butt squish against the floor too. Her stinky and squish diaper-clad butt that was already completely soiled because she hadn't even noticed that she had messed herself again. And after teasing her enough to make her cry her heart out and realize that she was just as bad as the girl she had bullied when she was just a Pissy Baby...

Poopy Baby Yukikaze gave Poopy Baby Shigure a hug. And a kiss to help her get used to this. She wasn't going to get a change in a long while, after all...
