[ABDL, Diaper Use, Soiling, Humiliation]

"You've gotten quite used to that pacifier, haven't you, Shiroko?"

Hoshino's teasing voice echoed out as two clubmates wandered through the empty halls of Abydos, as they usually would've done. The only difference from an ordinary day being the garments that were currently wrapped around their waists, that were so easy to spot as they reached out underneath their skirts. That thick, white and padded garment that was utterly embarrassing for anybody that got caught wearing it...

Sunaookami Shiroko and Takanashi Hoshino. Both part of the former Abydos Foreclosure Task Force. At this point, they were both little more than a pair of babies. What else could you call them if you saw their diapers? And given the smile on Hoshino's face, it wasn't going to bother her if she was called a baby. Shiroko seemed more embarrassed, given the blush on her cheeks, but the pacifier that was currently hanging from her neck like a necklace made it hard for her to deny it.

It hadn't been long since she had been forced into these garments either. She had just missed a single day of school, and now everything had gone wrong. Girls her age were all wearing diapers, and most of them were enjoying them sexually. Something that she had to admit that she had grown used to, since Hoshino had put her through the paces to make her a... 'Baby Slut'.

Hoshino giggled as she watched her friend tremble all over in response to her own thoughts. "You're daydreaming about getting a bit more training in, aren't you, Shiroko?" She chimed, which just prompted her friend to blush harder and look away from. "It's fine, it's fine. Once you're a fully trained Baby Slut, you'll understand what it means to be obsessed with diapers. You're already well on your way there, you know?"

Shiroko just stuffed her pacifier into her mouth. Not because she wanted to look more like one of those 'Baby Sluts' that Hoshino was training her to become, but because she simply found the squishy trinket to be nice and comforting. Which was honestly something she needed at the moment...

"You truly are adorable, Shiroko." Hoshino's giggling didn't stop, nor did the wolf-eared girl's cute attempts to deflect and get away from her result in anything but her head getting patted and her hair getting ruffled over and over. "You know, maybe you should catch up with the others? They're not as far along as me, but I'm sure they could use a little extra motivation by seeing you in diapers."

...That's right. There were more members of the Task Force. Surely they were able to hold out better than Hoshino. Surely they hadn't fallen to the same kind of perversion that Shiroko was slowly sinking into. At least, that was the fickle hope that Shiroko was holding onto. She just had to keep that hope within her heart.

Hoshino skipped over towards one of the many classrooms that had been repurposed for the sake of educating Baby Sluts, and casually tossed the door open. "Serikaaaaa, I'm baaaaaaack!" The pink-haired heterochromatic giggled, acting as lackadaisy as ever...

Shiroko poked her head inside, and quickly wished that she hadn't. Not just because the sight shocked her, but because it made her suckle her pacifier more. Which just made her depend on it more, something she wasn't supposed to end up doing...

"H-Haaaah! D-Damnit, Hoshino..!"

Squatting down in the middle of the classroom was one of the other members of the Foreclosure Task Force, Kuromi Serika. And she was as grumpy as ever, given the way she just glared towards the pink-haired girl that was supposed to be the president of their little group. But it wasn't the fact that she was squatting that was making her look shocking.

No, it was the teacher bot that was currently thrusting into her rear, all while a diaper was currently desperately clinging to her knees. Despite the fact she was getting defiled like this, she was able to keep control of herself to a remarkable degree. Even as her expression switched between a deep glare and spikes of pleasure that broke that gaze of hate...

Shiroko watched in a mixture of disgust and shock, squeezing her thighs together. It was a shock to see one of her friends get raped like this, but the disgust came from the fact that she was getting wetter by the second. And it wasn't because she was leaking into her diaper, even though Hoshino had already done a great job at ruining her control over her bowels and her bladder. No, it was pure arousal...

"You're still holding in? Wow, and here I thought you would've been broken after going through that so many times." Hoshino giggled as she took a seat on one of the nearby tables, kicking her legs around as she adjusted her seat so the diaper rubbed up against her in just the right way. "I brought Shiroko, so be a good Baby Slut, okay, Serika?"

"I don't want to be a Baby Slut!" Serika cried out, only for her eyes to widen as she felt the rigid cock slam deeper into her, right as her defenses had been weakened by her outburst. She was forced to mewl in pleasure as she felt something rush up through her anus, which just brought her more shame. Shame that intensified as her eyes fell upon the pacifier-suckling Shiroko. "N-Not you too, Shiroko. You're a pervert just like her..."

Shiroko quickly shook her head to try and disagree, but the glare from Serika made her tremble. Which, in turn, stopped her from holding back the flood of arousal that leaked into the front of her diaper, giving her a nice sticky wet spot that was so obvious that she had no way to deny anything...

"Ehehehe, she's definitely stinky enough to be one." Hoshino chimed, all while stretching a little. "I know you're a real stinker too, Serika. Why don't you just give in and accept it? You've been through this long enough, you can't possibly keep fighting back." She said, resting her head on the palm of her hand while she watched the girl slowly get her diaper fixed back onto her.

"Why'd you end up such a pervert so quickly?! What'd those two do to you?!" Serika shouted, grimacing as she felt the diaper press up against her crotch, while the wings were reapplied so it clung to her waist once again. It wasn't the best fit, but it at least would keep her nice and dry. Which was perfect, considering her stomach was starting to growl. "N-Not again..."

"Well, they taught me to be a good Baby Slut. Nothing else." Hoshino explained, all while getting off the table as she walked right over to her friend. Making sure that Shiroko was watching all of it, right as she pressed her hand up against Serika's plush pamper. "Besides, you're the one that brought them here. Aren't you the one that's supposed to take responsibility for what's happened?"

Serika glared right into Hoshino's heterochromatic eyes as she struggled to endure the pain in her stomach, only for her gaze to suddenly unfocus. "W-Wha..." She muttered, as it felt like her muscles were getting all sorts of weak. Which made it harder and harder to stand up. "Whas... happenin..?" Even her words were getting simpler, as everything started to grow nice and foggy...

Shiroko watched what was happening in front of her, with Hoshino helping Serika right down onto her butt so she didn't hurt herself, while also taking note of the white substance that was leaking off the robot's rod. It was thick, but it wasn't cum. It was more like... Milk?

"You know, if you had given in way before you got that enema, maybe you would've felt all nice and cozy instead of confused." Hoshino explained, all while gently rubbing Serika's tummy. "That stuff that filled your tummy... It's a special blend. It's really tasty if you drink it, but it makes you completely incontinent. Even I haven't had it up my butt yet. Aren't you glad you'll get to demonstrate it to Shiroko, Serika?" The pink-haired girl giggled, her own body trembling a bit. Ah, she kinda wanted to have a drink herself. Laying down beside one of her best friends and filling her diaper to the brim sounded really fun right now...

"D-Don't wanna! Don't... don..." Serika's words didn't just sound babyish, the way that she tried to protest made her look more and more like an infant. Which just made her look even more pitiful as she sniffled and sobbed, all while the pain in her tummy grew stronger and stronger.

*FRRRRRRRRRRRRRRRRRRRRRRRT*

And thanks to all the pain and the pressure building inside of Serika, she couldn't stop any of the filthy gas that had been clogged inside her either. The whistle-like sound of her stinky fumes forcing their way out between her cheeks filled the air, which just made her sob more and more. She didn't like this. She didn't like being infantile in this way, and she didn't like all the pain...

Shiroko watched. And she remembered what it was like when Hoshino gave her that crash course in being a 'Baby Slut'. This was.... This was way more intense than that. Serika's mind seemed to no longer be her own. The longer she had that enema inside of her, the more babyish she became. Not just with how she was about to fill her diaper, but the way she behaved. It was like... It was like having that stuff poured into her hole made her a real baby...

The sheer shame of what that must feel like. The humiliation. And the fact that she was doing nothing to try and help her friend... It made Shiroko pinch her thighs together to try and hide the spot that had formed on her diaper. But it wasn't hard to tell that she had managed to make her diaper all sorts of sticky already. She was soaked down there, and it was all because of the humiliation that somebody else went through. It wasn't right for her to enjoy this, and yet... She just couldn't stop.

The sound of her pacifier getting suckled on was one of the few sounds bouncing around inside of the classroom, besides the small symphony of stink that was rushing out of Serika's hole, as well as her constant sobbing. It was a backing track composed through pure shame, and it was everything that Hoshino loved to hear. Two Baby Sluts, well on their way to falling completely, audibly making their last resistance known.

"Ahh... You two are just the cutest. But you can't hold it any longer, can you, Serika?" Hoshino giggled as she let her hand slide further and further down. From that belly, right onto the padded crotch. Gently and slowly rubbing away at it with a massive grin on her face. She was going to push her right over the edge, and there was nothing that she could do to stop her. Not when she was this vulnerable.

All that Serika could do was cry out... Right until she felt Hoshino's hand push up against her padding. Right over one of the wet spots that led straight to her pussy. And as a result, she was forced to let out a powerful and potent moan, which served to loosen her up fully.

One loud *BRAAAAAAAAAAAAAAAAAAAAP* echoed out from her cheeks, the brassy sound serving to herald the flood of pure filth that was to fill the back of Serika's diaper. A flood that was stronger than anything she had ever experienced. Not just because of how wet her mess was, but because she had gone through the experience of being forced to shit herself more than a few times at this point.

And this was the worst of the bunch. Serika was sobbing from the depths of her heart as the back of her diaper very quickly grew deep shades of brown. She was crying and howling out in pure shame, all while she just couldn't stop pushing it all out. And to make matters worse, filling her diaper wasn't just humiliating...

It was liberating. It was like a switch flipped inside of Serika's mind. A switch that couldn't be undone. All of that shame and humiliation had managed to pile onto itself until she could feel nothing but delight at filling her diaper this extensively. It felt so good that her pussy was flooding her diaper as well, the front growing stickier and soggier with every moment. And not just because her bladder had been forcibly emptied as well, giving a yellow tint that contrasted the brown in the back.

Serika's cries turned into pure moans as she enjoyed this more and more. She was broken beyond belief, the sharp look in her eyes having turned to pure bliss. All while Hoshino smiled down at her, as if she was doing a good job. With her mind in this state, of course she took her heterochromatic friend's expression as a sign of relief. She was pooping her diaper, making a complete and utter mess of it...

And it was exactly what she should be doing. Filling it like this, feeling the mess underneath her grow bigger and bigger. Feeling it rub up against her, feeling the scent soak its way into her and reach all the way up to her nose where she could smell her own foul scent... It was awful, but it was also so right..!

Shiroko watched as Serika underwent a complete 180 in a matter of mere minutes. Seeing her fill that diaper to the point where she couldn't stop crying, only for that despair and shame to turn into pure bliss... It... It wasn't supposed to make somebody like Serika turn into a completely obsessed ditz who loved to fill her diapers. Was this what had happened to Hoshino to make her like this? Was... Was this what she was going to go through to complete her transformation into a Baby Slut..!?

The more that the thought dwelled on her mind, the less Shiroko could stop herself from making a mess. Only as she felt the subtle sensation of something spreading out her cheeks did she realize that she was in the middle of pooping herself, which just caused her to whimper as the back of her diaper pushed out further and further.

Her mess was nowhere near as large as Serika's, but it was definitely stinky. While she could smell Serika from here, it was nowhere near as pungent or as overpowering as her own smell. It was so strong that she was sure that she was going to knock herself out if she kept smelling it...

And the more she smelled her own mess, the more she saw Serika fall, the more she started to just give up. Which was why the front of her diaper grew nice and wet too. Her bladder just loosened completely, and all of the pee that was still stuck in there quickly soaked its way into the front of her padding, making it much soggier than when it had only been soaking up her juices...

"D-Diapy... Squishy..." Serika gasped and panted, drool running down her chin while she looked like she had drowned in her own pleasure. There was not a single speck of her resistance left on that face. Just pure enjoyment. As expected of a Baby Slut that had been broken in completely.

Serika's moans returned as Hoshino made sure to push her hand up against that extra sticky and extra stinky diaper, which also made the two giggle as they were both enjoying this way more than one really should. "Diapy..! Aaah... Messy diapy... Luv..!" Serika cried out in delight, trembling all over as she was on the verge of cumming all over again, just from a little bit of teasing like this.

"That's right, Serika. You should love your messy diapies. That's why you're a Baby Slut." Hoshino chimed as she continued to tease away at her, before pulling her hand back right as she saw the girl go through another climax, making her body writhe all over. All while she shot a glance towards Shiroko and started giggling. "And you look like you're well on your way too, Shiroko. Did you enjoy the show?"

Shiroko's eyes widened as she realized what had happened, before she tried to get away. But before she could do so, the slurred giggle of the babified Serika froze her in place. All while that black-haired Baby Slut crawled towards her, dragging the extra messy diaper along the ground and leaving a wet trail.

"Stinky... Biiiig stinky... Gooooood..." Serika giggled as she crawled all the way over, before wrapping her arms around Shiroko's legs and pushed her face up against that dirty diaper. Not right against the mess itself, but the pee-soaked front was nice and stinky too. "Gooooooood...!" She cried out, trembling as you could audibly hear the front of her extra soaked diaper push out a little further...

Hoshino giggled a bit more as she came closer, putting a single hand on the browned part of Shiroko's diaper. "She's right, you know. You made such a big stinky, and we didn't even have to do anything." She said, pushing it up against that dirty Baby Slut's butt to make sure she couldn't escape that feeling. "You're a natural, Shiroko. Perhaps it's time to move onto your next lesson? I'm sure you'd like to be just like us."

Shiroko couldn't do anything except suckle on her pacifier as she felt them both tease her like this. She was lucky that she was spent, otherwise she'd be filling that diaper even more. But it didn't stop her from squirming and suckling harder. She... She didn't want to be a Baby Slut. But it was getting harder and harder to fight back. Especially when Hoshino's voice sounded so nice...

"You're such a good girl, Shiroko. You'll be an even better Baby Slut than me, just you wait and see..."
