[ABDL, Soiling, Yuri, Bondage]

"It's nice. Really nice."

"I guess it is. I would never have imagined that Wakamo could be so adorable as a Maid, nor so obedient! Not to mention, we don't have to worry about money anymore... Ehehehe..."

"Mmhm. Really cute."

Within one of the many classrooms that dotted AByDoS' sat two of its prestigious Diaper Sluts. Shiroko, who was currently pressing her fingers up against her diaper, and Serika, who was rocking back and forth on her own diaper. All while enjoying their new lives...

Sure, they had been trained to be good Diaper Sluts. As the Principals intended for them to be. But they had grown used to it, and they actually rather loved it at this point. And what really gave them a spark of joy was the fact that they got to lord over any newer Diaper Sluts that arrived. Which just happened to be the case with little Wakamo.

Now, Wakamo wasn't an ordinary Diaper Slut by any means. They were very well aware of that. She was the lowest of the low, a punishment that she had been dealt thanks to everything she had done in the past. So even if they weren't her seniors, they'd still get to bully her. But since she had been personally trained by the Principals to make sure that she was such an adorable Diaper Maid, they got to do whatever they wanted to her. And she'd have to change them. Regardless of how much they had abused her!

"Ehehe..." Serika giggled a little to herself, as she continued to grind back and forth to raise her arousal. All while thinking what an adorable expression had been on Wakamo's face. The poor girl, without her mask to hide behind, had been sobbing adorably. Both when she was forced to push up against Serika's messy diaperbutt, and when Shiroko had used her as a seat...

Shiroko continued to stroke her fingers up and down along the side of her diaper. All while thinking of the sounds that Wakamo had made while she used her as a seat. Sounds that were even cuter than the ones she had made while she was being trained.. On some level, she did pity her. But the arousal that came from humiliating her and bullying her was too much to pass by. Which was why she had been so enthusiastic about the whole thing.

"You think the Principals might get us a brand new Diaper Maid, Shiroko? So we each have a personal one?" The pleasure was getting to Serika. As delusions of grandeur started to fill her head. This always happened whenever they ended up getting a little ahead of themselves. Even if Serika was also seemingly the most responsible of their little club, that didn't stop her from going overboard...

"I think they're going to be very disappointed once they find out what you two did to poor little Wakamo, Serika, Shiroko."

Before Shiroko had a chance to answer, somebody else had taken the opportunity. And her gentle voice sent a shiver down Serika's spine, while Shiroko's own red cheeks lost their aroused color. They were both being reprimanded. Not by one of the maternal Principals, but rather by one of their own...

The one that was talking to them and chewing them out was none other than Nonomi, who wore an expression filled with concern. An expression that was also very clearly disappointed with the two girls, as they could both feel a certain kind of sharpness poking at them as she stared towards them...

"W-What do you mean, Nonomi? What's wrong with what we did to Wakamo?" Serika asked, sweat pouring down her cheeks. She hadn't heard anything about what they were and weren't allowed to do to her. What were the guidelines for Diaper Sluts anyway? The Principals didn't say anything, and the robots that were set up to help them train weren't any help in that regard.

Shiroko wanted to stop playing with herself. But... Having Nonomi talk her down like this was also arousing. Which caused her to shamefully rub at her crotch a bit more, even as Nonomi's gaze turned into a soft glare. She didn't like it... And she didn't like that she liked it in that way either...

Nonomi sighed as she stepped closer to the two Diaper Sluts. All while her own pristine diaper crinkled neatly between her thighs. Truth be told, they hadn't really listened in on how she had been broken. But she seemed more dominant than before... Had she been personally trained by the Principals..?

"I know Hoshino was there when her transfer was authorized, so maybe I have to talk to her as well." Nonomi began, before crossing her arms and shaking her head. "Our Principals were very clear. You two were only meant to greet her and introduce her to the curriculum. You weren't meant to abuse her and make her act like she was just there for your amusement. Do you know how much she cried while you sat on her chest Shiroko? And how much she sobbed after she had been stuck against your diaper for so long, Serika?"

It was bad enough to be scolded by the tall white-haired Mommy that served as one of their Principals. It was even worse to have Nonomi scold them. Especially since her words just happened to cut much deeper than they ever had before, hurting both girls a lot more than they could've expected.

"B-But... S-She's a criminal, right?" Serika trembled as she tried to argue her way out of it. "S-She's caused so much bad stuff, why couldn't we have a bit of fun with her?" Indeed. Wakamo had caused so many terrible moments all across Kivotos. So why... WHy weren't they allowed..?

Shiroko didn't try to defend herself. Merely looking down at the floor, while at the same time pushing her fingers against her diaper even more aggressively. Hearing Nonomi chew her out really was so arousing. Despite the fact that it really shouldn't be. She shouldn't be growing so horny just because she was being scolded...

"Even if she's been such a bad girl, that doesn't give you the right to be a bully towards her, Serika." Nonomi said, turning to Shiroko as she stepped closer to the naughty girl. "And it doesn't give you the right to pin her down and make her smell your dirty diaper for so long either, Shiroko. But you probably don't care. You would have your hand off your diaper if you did." Her words were sharp, and really hard to avoid taking to heart...

But using her words to harm them and remind them that they had been bad girls wasn't the only thing Nonomi could do. No, the smile that worked its way onto her face as she took a few steps back was perhaps even more chilling than her glare. "Now, since you both understand that you've been bad... How about we get right to what you two deserve?" To go along with her gentle smile, her voice had turned gentle too. Even though she was about to subject the two girls to something truly terrifying.

"It's punishment time for bad Diaper Sluts."

Her tone turned 180 in the span of a single second, and neither of the two were prepared for it. Just as they weren't prepared for the arms that suddenly shot out of both the ceiling and the floor, with those mechanical appendages quickly aiming for their arms and legs.

Normally, Serika would be ready to protect herself from such an attack. But she could only shriek in shock as she was very rudely grabbed by the mechanical arms from the ceiling. The sheer surprise of their appearance caused a loud and audible hiss to echo from her, as the front of her diaper quickly yellowed while she was grabbed...

As for Shiroko, she didn't have time to defend herself either. Even if she did, the fact that she couldn't stop masturbating probably meant that she wouldn't be able to do anything regardless. Instead, all she could do was whine in a needy manner as her arms were tied behind her back and her fingers were kept as far away from her diaper as they possibly could be.

Once the two naughty girls had been thoroughly tied up, preventing them from moving in any real capacity, the arms that had grabbed them put them down on the floor. But instead of letting them lie side by side, where they could at least have some form of time to recover... The arms tied them together, to make sure that neither of them escaped their impending punishment.

Nonomi smiled as she looked down upon the two girls, who were now tied together in an utterly humiliating way. With Shiroko's face pressing up against Serika's wet diaper, and with Serika's face pushing up against Shiroko's slick and juice-filled diaper. Both having used their diapers in a moderate way, and both of them could tell that it was going to get way worse...

Shiroko tried to pull her head away from the wet diaper in front of her. Mainly because it was too stinky for her. She wasn't a fan of proper messy diapers either, but she hadn't grown used to the wet smell of a thoroughly soaked diaper. Especially not as she could hear Serika wetting herself more and more... That girl just couldn't stop once she had begun...

But as she turned her head away, she stared straight at a pristine white diaper instead. Which made her heart sink, because it was easy to tell that it was Nonomi's. "N-Nonomi... W-Wait..." This was bad. She could already feel her stomach turning thanks to the smell of the pee-filled diaper. But if Nonomi started to do something like this, then...

"You should've listened to Wakamo when she asked for you to wait, Shiroko. This is your punishment!" Nonomi said with such a gentle tone, despite the horrid actions she was taking. All while pushing more and more, to get rid of the faint pressure in her tummy...

It didn't take long for the back of her diaper to start expanding, with the browning surface quickly pushing up against Shiroko's face. An action that caused Shiroko to wince and whine as she felt the smell force its way into her nostrils. Forcing her to experience everything bad about this smell, as she felt her stomach turning more and more. She was trapped between a rock and a hard place. Between the foul smell of Nonomi's poop-filled diaper, and the slightly more acidic scent that came from the soggy diaper she was meant to be pinned against.

Once she had been exposed to the two scents, two things happened in turn. Firstly, Shiroko could feel the contents of her bowels and her stomach loosen as they were being pushed into her diaper. Quickly ruining what parts of her diaper hadn't grown wet thanks to her juices. And at the same time, she felt a pang of arousal smash through her, to the point where she was forced to dig her face into one of the two diapers to muffle the scream that left her lips moments later.

Every Diaper Slut in AByDoS had been thoroughly trained to cum when they messed themselves. And vice versa. No matter how horrid the smells were, no matter how they were being forced to fill their diapers... They were unable to avoid the orgasm that came with it. Leaving Shiroko to moan and whine like the adorable puppy that she was, regardless if she wanted to or not.

Serika was not too happy to be faced with a big brown diaper pushing up against her face either. Especially not when she could also smell the scent of Shiroko cumming as well. How was she supposed to handle it, when Shiroko clearly couldn't? Combine that with her fear, and it didn't take long for her to start pushing on instinct either...

Once she started pushing, it wasn't long before she started cumming either. Letting out a muffled howl of pure arousal as she felt the shitty sludge pouring out from her ass. She hated it, almost as much as she hated the smell that was being pushed into her face. She couldn't pull herself away from Shiroko's diaper either, because it was still growing. Even if she were able to turn her head, she'd just turn it into another part of the diaper. Which meant that no matter what happened, the orgasming girl was forced to push up against that stinky mess.

Her diaper thankfully was more than capable of handling any size of mess. Part of her training to become a Diaper Slut involved measurements being taken, ensuring that her diaper wouldn't overflow unless that was desired. And at the moment, the diapers that she and Shiroko were wearing were meant to hold as much as possible. Which was both a blessing and a curse. A blessing because it meant that they weren't getting dirty, and a curse because the stink was so concentrated...

Something that Shiroko had to curse, as she wasn't even trapped between two different options at this point. She was trapped between her friends' poopy diapers. Her poor nose was completely annihilated by the sheer amount of stink pouring around her, which just made her cum more and more, and that in turn made her push more. It was a never ending cycle. Even if Nonomi pulled herself away at this point, it was practically guaranteed that the poor girls wouldn't get the chance to break free...

And that was all the more obvious as the two girls started to violently fart in between pushes. It was actually absurd how much they were able to pack into their pampers, and the *FRRRRRT*s and *BRAAAAAAAAAAAAAAAAP*s that echoed from their rears only served to emphasize it. Which brought both of them even more shame, and even more arousal as well.

All while Nonomi smiled and laughed at their predicament. Slowly rocking back and forth on top of her diaper, as she kept a close eye on the two of them. When Wakamo had come to talk to her to try and get help, she had expected that the girl had been bad. But no, Wakamo had done everything to follow orders. And she just didn't understand why they were so mean.

There's no way that Nonomi could let a girl like that cry for long. Even if Wakamo had been such a terrible soul prior to her training, she was making a genuine effort to live up to her new role. She even happily reported on further training with the Principals, and asked Nonomi if she could get custom diapers. The girl was a little sister to her... Which was why she had decided that it was best to punish the two.

Of course, Wakamo wasn't going to avoid dirty diapers just because she had been bullied and they had been punished. It was still her duty to clean up after messy accidents and play like this. But at least she wouldn't be forced to indulge in the smell... Unless she wanted to, at any rate.

Eventually, Nonomi's messing came to an end. But that didn't mean she stopped sitting right up against Shiroko's face. It was a very nice place to sit. Very cushy, very soft. Even if a lot of that cushy feeling came from how nice it felt to sit on her own mess. It felt so good that she could just let her hand drift down and slowly rub away at her crotch...

All while listening to the wonderful sounds of the two girls struggling. They were just adorable like this. There was absolutely no way that they were going to be free from their little predicament. At least, not any time soon. And she was just lapping it up. Enjoying their misery, because of what they had done...

"S-Stinky... Stinky..!" Serika cried out in vain as she tried to pull herself away from Shiroko's diaper, but all that she ended up doing was pushing herself deeper into the messy cushion, causing her to whine and gag as she was forced to fill her diaper even more. All while a few tears ran down her face. Tears of pure exhaustion, overwhelmed by everything.

Shiroko was barely in any better condition. She was stuck between two diapers after all. And the more that Serika ended up filling hers, the more she was pushed into Nonomi's. Which then pushed her back towards Serika's whenever Nonomi rocked a bit too much back and forth. She truly couldn't escape either way, which just made the girl whine as the tears started to stream down the sides of her face too.

"N-Nonomi... I'm sorry, we're sorry..!" Shiroko tried to cry out, despite how muffled she was due to the sheer amount of poopy she was buried under. "Please... Please let us go! We promise we won't be bad again..!" She truly did feel awful. And while this was mainly a ploy to try and get free, she would also do anything to avoid it again. Being stuck underneath two dirty diapers was just terrible!

"Ehehehe... Noooope..." Nonomi said, her voice barely audible due to the gentle moans slipping from her lips as she continued to press her fingers up against her diaper... She wasn't too keen on freeing the two girls. All because of how good it felt to play with her diaper. Even though she was clearly the most mature of the AByDoS girls, that didn't stop her from being a Diaper Slut just like them...

And as she kept them both pinned and trapped within the endless cycle, the Maid that had been the target of the girls' bullying quietly watched from outside the room, whimpering in mild delight from the sight of them getting what they deserved...

Nonomi had paid her back... And Wakamo would make sure that Nonomi got the best treatment that a Diaper Maid could possibly give her, as thanks for all her help...
