[ABDL, Soiling, Diaper Use]

"H-Haaah... I-I'm... I'm a Naughty Diaper Slut..."

A moan echoed throughout a mostly dark room, as a young lady was busy pressing her fingers up against the crinkly garment between her thighs. All while watching the screens in front of her, the screens that were showing off such horrid imagery that would make most people gag, or otherwise evoke repulsed reactions within them.

She had seen this stuff so many times. It was why she repeated that mantra. It was what she had been taught as part of AByDoS. And this was her way of studying. She didn't like doing a lot of it herself, but if she just kept watching it, then she could learn. Especially since the videos on display were of her dear friends...

On one screen was the pink-haired Hoshino, who was currently wrapping her lips around that metallic shaft that she had trained so much with. Leaving it smeared with her saliva, all while her wet diaper sagged between her thighs. Only growing heavier in response to the juices that were leaking into it. Giving into the lessons that a Naughty Diaper Slut was taught over and over, eagerly enjoying herself...

On another was the grumpy Serika, the video showing one of her very first lessons. Her diaper tugged down between her thighs while she was bent over, allowing her pussy to push up against the crinkly fabric while allowing access to her rear hole. Her poor hole being spread out by the metallic shaft, making sure that she wouldn't be able to close it... While at the same time generally training it, so she would be able to service anybody that wanted to have fun with the trained Diaper Slut. Especially since she kept on moaning, despite how rough it was...

But those two screens weren't enough. Though they showed such a depraved image, merely having sex with some of the robotic teachers wasn't enough. It was never enough for the Naughty Diaper Slut that was rubbing her hand up against her diaper, especially as she focused her eyes on the dirtier stuff...

The rebellious Wakamo's induction was on one of those. How she got trapped underneath Shiroko's diaper, and how the girl was happy to push everything out while she was using the soon-to-be-maid's face as a seat. The disgusting sounds amplified by the speakers, echoing around in the room...

Mixing together with Shiroko getting punished for being far too mean to the maid, courtesy of Nonomi's diaper being right in front of Shiroko's face. It wasn't the only diaper that was close to Shiroko's face either, but the footage was filmed in such a way that you could only see Nonomi and Shiroko. And the audio definitely focused on the brassy sounds, with farts echoing out from the speakers...

These four videos were ones that the Naughty Diaper Slut had been watching for a long time. All by herself. All in the comfort of her special room. Where absolutely nobody would disturb her, and she could just masturbate to her heart's content.

"Haaahh... Haaaah...! I'm a Naughty Diaper Slut..!"

The sound of a climax echoed through her room, as she made a mess of her diaper. The juices were gushing from her pussy as she collapsed in her chair, and her glasses slid off her face slightly. No matter how many times she went through this, no matter how many times she came to her friends being Naughty Diaper Sluts that were happy to fill their diapers, it never ceased to leave her floored...

Her name was Ayane. And out of the five members of the old Foreclosure Task Force, she was the one that had secretly fallen the hardest. Not to the point where she'd happily fill her diapers with actual poopy, but she had definitely lived up to the slut part of their new status. She almost wanted to show it to the principals, to make them praise her... But she knew that if she did, then she'd  just bring attention to her. And then she couldn't keep having fun like this. It was a real shame...

"Haaah... Haah..." Ayane muttered as she slowly sat up in her chair once again, adjusting her glasses as the warmth of the afterglow washed off her. She was done cumming. Now all she had to do was figure out what other videos she needed to play, and-

The black-haired girl froze as she noticed that the screens had all turned off. And now the only thing that lit up the room... It wasn't those screens. No, it was something far more terrifying. Something that filled her heart with dread...

Light emanated from four halos floating in front of her. Four halos that she was intimately familiar with. Four halos that immediately made her try to get out of her chair, because there's no way that she could properly explain what she was doing. Especially with her seat having been soaked from how much she had been masturbating, and how soggy her diaper was..!

"Oh no. You're not getting away."

The lights turned on, revealing the other members of the Foreclosure Task Force. And as soon as those lights turned on, the only thing that Ayane really saw was Hoshino's smile, right before she was forcibly tied to her chair thanks to quick teamwork from Serika and Shiroko.

"And here I thought they were the naughty ones for bullying Wakamo so much." Nonomi muttered as she stood right beside Hoshino, shaking her head while looking at Ayane. "You've been watching us all along, without even trying to help us out? Don't you feel ashamed, Ayane?"

Ayane didn't know what to say. Nonomi's words cut really deep. As the nicest girl among them, she would never want to disappoint her. And yet that's exactly what she had done. "N-Nonomi, H-Hoshino, I-"

A moan left Ayane's lips before she was able to muster up an apology. All thanks to the more forceful fingers roughly grabbing her padded and extra soggy crotch. All thanks to the diaper check she received from Shiroko, another moaning following after that as she felt a hand grab onto her dry diaper butt...

"Wet in the front." Shiroko commented, pulling her hand back as she revealed just how drenched it was. Almost as wet as it'd be if she had been the one cumming so much. Then again, it'd be extra messy too, given how much her orgasms and her poopy had been linked at this point.

"And completely dry in the back." Serika scoffed a little as she pulled her hand back. "You haven't even been messing your diaper. You're slacking while not helping us either. What do you have to say for yourself, Ayane?" Even though the screen had been showing how badly she had been fucked by the robotic teachers, she was still as tight-assed as ever. At least in that way...

"I-I..." Ayane squirmed in her chair as she knew that she couldn't really say anything without the four judging her. She knew them well, and they knew her well too. "I-I just... I just don't want to make my fluffy diaper dirty, it's all sorts of sticky if I go poopy in it..!" Both an excuse for her actions, and the honest truth. She much preferred the wet sensation of cumming into her diaper over and over, compared to the gross sensation of having all that stinky stuff rub up against her...

Serika glared, and Shiroko just stared with mild contempt. Nonomi shook her head, showing how much the three really disapproved of her attempt to excuse her actions. But the only one that didn't really mind was Hoshino, who giggled in response.

"Oh? Well, then we just need to make sure to finish your training. Isn't that right, girls?" Hoshino chimed, and a light lit up in the other three girls' eyes. Which filled Ayane's stomach with dread. Whenever Hoshino was a little too excited, that probably meant that she was in for a very, very difficult time. She was going to end up filling her diaper one way or another, that much was sure now...

Nonomi smiled as she reached for a bag that she had brought with her, all while Shiroko and Serika took up positions at Ayane's side. Both of them put their hands on her head, so they could keep it nice and steady. No matter how much she shook, no matter how much she wanted to struggle. They weren't going to let go of her.

"Now." Nonomi said, as she revealed everything that she had brought. Several small bottles full of some sort of sweet-scented liquid, as well as plenty of pills. All of which Hoshino held for her, so she could focus on feeding it all to Ayane. "Open up, Ayane. Then we can get started on your lesson."

Her words were sweet, despite what she was going to put the girl through. And that almost made Ayane want to open up her mouth. But if she let that slip in, then-

She didn't get a choice. As soon as Serika and Shiroko noticed that she was being difficult, they forced her mouth open. They were both a lot stronger than they looked, or maybe Ayane had never really taken notice of their strength because she never expected that it would be used on her. But with her mouth open, there was little that she could do to stop Nonomi.

Teaspoon after teaspoon of sweet syrup poured onto her tongue, with a couple of pills peppered onto each glob to make sure that she was properly medicated. And it didn't take long for Ayane's stomach to start throwing a fit in response to all the medicine it was digesting...

And it only got worse once they got through the back half of all the medicine. Laxatives. That was what the syrup was. And what the pills were. And it was all wreaking complete havoc on her stomach...

Nonomi giggled, as she patted both Serika and Shiroko on their heads. They had done well, and deserved praise. An act that caused them both to tremble a little as Ayane swore she could hear them peeing their diapers... And the way they squished their thighs together definitely caused a wetter sound to echo out as they joined the other two girls in front of Ayane...

"I-I don't... I don't wanna go poopy..!" Ayane protested, despite how much her tummy was hurting. Not only was it hurting, but she also felt super bloated. Like she had to fart a lot too. Which was going to be almost as humiliating as going poopy in her pampers..!

Hoshino giggled, as she and the other girls turned away... And bent over slightly, to bring more emphasis to their diapered butts. All of which were nice and soaked. Hoshino and Nonomi's own way more than the two girls that had climaxed a tiny bit from being rewarded with headpats.

"Don't worry, Ayane. All you gotta do is push. Like a good Naughty Dirty Diaper Slut!" Hoshino cried out, emphasizing the dirty part of their title. All while pushing and grunting, as her ass started to let out a faint *frrrt* to start.

Following in Hoshino's lead, the other three started pushing as well. With Shiroko's farts quickly overpowering all of the others, her brassy butt loudly and proudly letting out a *BRAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAP* as one could visibly see her diaper reacting to the force of her fart...

Just like Ayane was forced to react to the sheer intensity of the stink wafting from her rear. It was toxic. Poisonous. If it wasn't partly muffled by the diaper, she was sure that she would've passed out right then and there. But it stunned her just enough that by the time she regained some semblance of control...

She was blasted with the stink of all four girls combined. Their mushy messes sank into the seats of their diapers, as each of them pushed more and more. The amount of poopy being packed into their seats wasn't equalized, but that didn't matter. The stink was mixing together regardless, making it all blow towards Ayane in one big clump...

A single whiff of that was too much for Ayane. Right as she gagged in disgust, her defenses lowered, and a loud *FRRRRRRRRRRRRRRRRRRRRRRRRT* left her inexperienced hole, causing her eyes to widen in shock as she felt a filthy sensation underneath her.

She was pooping herself. She was pushing into her diaper, and she couldn't stop. In fact, she didn't realize she had even started pushing. Maybe it was when she was stunned for a brief second by the sheer intensity of that smell, but it didn't matter either way. The reality was that she was filling her diaper.

And not just a little. She was pooping hard and fast, causing her diaper to slip down from her waist a little. Not to the point where her tapes were undone, but you could definitely tell that she was filling it. Especially as the seat of the diaper was starting to leak out over the front of her chair.

All while the tears started to run down her face. She couldn't believe that she was able to poop this much. It was humiliating and eye-opening at the same time. She wanted it all to stop. She wanted it to stop so she wouldn't have to think about it, and so she didn't have to confront reality. But the fact of the matter was that she was filling her diaper...

Just.... Just as they were. Just as they had all done so many times before. Her horror and shock was quickly being replaced by a sense of depraved camaraderie, as the lessons finally sank in. Evident by how her legs squeezed themselves together, and really squished up against her diaper. Really making the sound of her packed pamper echo out...

"H-Haaaah..." Ayane gasped as the smell of her friends' stink... It was nowhere near as bad as it was just moments prior. If anything, it was comforting and welcoming. All while a bit of drool ran down her chin...

"A-Ayane... N-Naughty Dirty Diaper Slut... E-Ehehe..." She couldn't even really say anything thanks to how much she was experiencing. The pleasure, the humiliation, the shame, everything melding into a single messy swirl inside her head. Allowing her to do nothing besides giggle and look like a broken ditz. A ditz that was happy to fill her diaper with such a stupid look on her face...

Hoshino looked over her shoulder, before nervously giggling a little herself. "I think we might've gone a little overboard..." She muttered. What else were they supposed to take from Ayane's current state? She was still pushing too, given the way that the diaper sank a bit further over the edge of the chair...

Nonomi gazed as well, before chuckling. "She looks almost like you did when you first got treated by our Mommies, Hoshino." She chimed, sighing sweetly as she recalled the first few days under the Principals of AByDoS... No, the Mommies of their little school...

Hoshino quickly started blushing after that, as both Serika and Shiroko cast each other a glance too. Everyone had been through this, really. The moment where they broke completely and became the stinky babies that they were meant to be. The Naughty Dirty Diaper Sluts that loved to pack their diapers to the brim...

Ayane giggled a little, still not fully aware of anything anymore. All while she just kept on pushing... Until the sound of her diaper leaking echoed out, and a bit of stinky brown liquid started to force its way down her thigh. She definitely needed a change once everything was said and done. And hopefully, her mind wasn't completely broken by the time they got her a new diaper. So she could focus on what was really important. So she could focus on being a stinky baby. Just like her friends were...

"Oh dear. We're going to have to put her in the same diapers we use for Wakamo, if she's starting to leak." Nonomi said, before gently patting Hoshino on the back. "Since it was your idea, you're in charge of changing her. Okay, Hoshino?" She chimed, being overly friendly... But a suggestion from Nonomi was more like a command, considering the kind of dominance she hid under that soft personality of hers.

"O-Of course." Hoshino nervously laughed, before taking another good look at Ayane. And her worries just faded away. There was something so sweet, so relieving, about seeing her friend end up just like her and the others. The five of them were finally together again. As stinky baby sluts, sure, but they were happy to be like this. Filling their diapers and servicing those that needed it... That was what fueled them. The satisfaction of living up to those expectations.

Serika huffed a little as she stood beside Ayane's chair. "Still, she spent all of this time watching us all fill our diapers. The least she could've done was put it to work, so Mommy'd give us some allowance!" She brattily commented, enviously staring down at the mess that the girl had made. She really needed to push more if she wanted to catch up to what Ayane was able to put out.

Shiroko took her position as well, merely smiling as she took note of the size of Ayane's diaper. And the smell too. Very, very smelly. Maybe... Maybe she could introduce her to the special play that Nonomi had forced her to try. That'd be fun...

Nonomi giggled as she watched Hoshino take up a spot near the chair as well, before she pulled out her phone and posed together with the other three and the diapered ditz that still hadn't recovered. "Say cheese, everyone! And let's do our best as Naughty Dirty Diaper Sluts from now on!"

The flash brightly shone from her phone, as Nonomi snapped a selfie of her and the rest of the former Foreclosure Task Force. Now nothing more than dirty babies, AByDoS' finest sluts...

From now on, it was up to them to teach everyone how good it felt. Especially once their Mommies finalized those transfers they heard about...
