[ABDL, Diaper Use, Farting, Soiling]

Among the many T-Dolls that had come to the Commander's aid, there were two that stood out. The pleasant-minded AK-12, and the stoic AN-94. At a glance, they both carried themselves in similar fashions, with their performance on the battlefield showing why they were often requested by other factions. And yet here they both were, joining a seemingly innocuous armed force.

Of course, what the Commander didn't know wouldn't hurt them. AK-12 had a secret that she had been very diligent in keeping ever since she arrived at the base, to the point where she was able to carry out that secret even on the battlefield. And what was that secret exactly?

She was a huge fan of being a baby. So much so that she had been padded ever since she stepped foot on the base. Thanks to her high marks during excursions, she was given more freedom than any other T-Doll, which meant that nobody dared to wander into her personal quarters since she always seemed so busy. If they even dared to try and come in, they'd realize that her 'busy' behavior was just a front that would let her waste her free time away laying on her padded floor, squeezing her fingers into the diapers that she loved so much.

Unfortunately for her, there was only so much fun that you could achieve by yourself. AK-12 had a lot of fun being a baby, but she desperately craved somebody's touch during her fun little sessions. Whether it was from an 'adult' or a fellow baby sister. As she knew she couldn't breach the concept of her fantasy to the Commander without possibly being requested to quit her antics, she had to turn to something desperate. Something that she normally wouldn't do, mainly because she'd be seen as a bigger pervert than she already was.

Today was the day that she was going to carry that desperate plot out, as she started knocking on the door to her fellow T-Doll's room. "AN-94? Are you in there? I wanted to have a little chat about your performance during our last fight together, see if we could compare notes and figure out ways for the two of us to improve." AK-12 said with a gentle tone, not wanting to arouse any suspicion quite yet...

Initially, she didn't receive an answer. After she knocked on the door an additional time to ensure that she had been heard, the door opened to reveal the platinum blonde's face peering back at her. "...Come in. You look too happy." AN-94 remarked a little sluggishly before opening the door fully, letting her comrade inside...

"I'm happy because I've been doing good, you should learn a thing or two about that, AN-94." The silver-haired girl replied with her smile still reaching from one ear to the next as she stepped inside. In the process, she revealed a rather strange looking bag resting underneath her shoulder, making the room's owner stare at her with a raised eyebrow. "Hm? What's the matter? You look like you've seen something you shouldn't have."

The room owner wanted to speak up, only to blush a little as she muttered almost incoherently. "You've brought a bag. I... I don't know why you'd want to bring a bag into a friend's room."

AK-12 laughed a little in response to the shy display from her compatriot. "You've got a way with words that even I could've never thought of. Here, why don't I show you what's in it, then you might be able to tell why I brought it." She was quite pleased with the response she got, as she slowly unzipped the bag...

Only to reveal baby supplies upon baby supplies. Wipes, baby powder and a whole bunch of thick diapers that looked excessive even by adult diaper standards. This was enough to send the platinum blonde into a sense of shock, slowly stepping back to try and get away from the strange girl that had just come into her room.

Her indecisive way of trying to escape just resulted in her wrists being grabbed by the silver-haired T-Doll, who continued to smile rather pleasantly. "Ah-ah. You're not going anywhere. We're about to have a lot of fun together, without any kind of interruptions. You're going to look so cute once I'm done with you."

AN-94 struggled against her friend's grip, her blush growing bigger as she was touched. "G-get off!" Her voice was stammering thanks to the way she had been thrown off, which served to make her even less intimidating than she ever could've. In fact, the way she was protesting made her look even cuter, which just made her friend want to bully her even more.

AK-12 licked her lips as she forced the other T-Doll to the ground, using her superior grip and dominance over the situation to enforce her wants. It didn't take long for her to strip the girl either, as her clothes quickly started piling up in a corner of the room as each article was haphazardly thrown over to the exact same spot. "You know, you're pretty cute when you're trying to show that you're an adult. Shame you really aren't one, AN-94."

"W-What do you mean I'm not an adult?" The platinum blonde asked, feeling littler by the second thanks to the way she was being treated. It wasn't fair, she wasn't supposed to be acting this way. Neither her nor the silver-haired girl atop of her. It wasn't fair at all, so much so that she started tearing up a little...

The 'bigger' girl continued to smile as she wiped away a few of the tears that were running down her friend's cheeks. "You're proving yourself to be a big baby when you start crying just from that accusation, AN-94. But don't worry, that's why I came prepared. That's why you're going straight back to diapers until you can learn to be a big girl again." She chimed cheerfully despite the gravity of the situation at hand.

AN-94 wanted to stop what came next, but the uninvited guest opening her eyes to briefly glare at her made her quiet down and sit still for the time being. Just as a good baby should. She squirmed as she felt the baby powder slowly coating her nethers, leaving her nice and caked in the stuff so that she wouldn't get any rashes due to what was coming up next.

She was gently pushed onto her back so that she could raise her legs up high, just so that her 'caretaker' would have an easier time sliding one of her huge diapers underneath her cute buttocks. Once it was firmly secured and both cheeks were snugly pushing against the plush insides of the padding, AK-12 weaved the middle parts of the diaper through the girl's slender thighs before pushing the front up against her crotch and snapping the tapes shut on the sides of the padding, ensuring that she wasn't going to get it off very easily. Especially with the way that she had rather successfully struck fear into the poor girl's heart.

"N-Now what?" The platinum blonde muttered as she carefully tried to sit up, only to immediately lean back down as she felt her thighs pitifully squish together with each of them pinching the bridge of the diaper. She didn't like the sensation, not one bit. It was humiliating to have something so thick between her legs, and especially when somebody was staring at her with that ever-mocking and ever-present smile of hers...

AK-12 couldn't help but giggle as her friend made it clear that she just wanted all of this to be over already. "Come on now, AN-94. We've got so much more to do before you're done." She chimed still as she slowly tugged down her pants to reveal her secret, making the padded girl widen her eyes further in shock. "After all, I still haven't really used my diaper, so why should we be done when you've just been put in a clean one yourself?"

It didn't take a genius to understand what that mean girl was implying. "N-No, you couldn't... You wouldn't..." She muttered, her stoic expression and behavior having completely broken into a shy and whimpering mess ages ago. The fact that her friend was about to make it all worse by using the diaper was just the icing on top of her humiliation...

"Of course I would, silly. I'm going to make sure that you use your padding by using my own. It's the only fool-proof way that I can use to make you a big baby..." The older of the two girls laughed a little as she positioned herself so that she'd have the best possible seat- Her dear friend's cute face. "And really, what better way than embracing my own inner baby?"

AN-94 wanted to scream, but she didn't get a chance. Immediately after her friend's declaration, she was met with a thick layer of padding squishing down on her head. It was soft, unfathomably so, but that didn't make things any better. If anything, the fact it was so soft made it worse! She could still breathe at least, even if the softness made it hard to turn her head or look any other way...

Though she'd soon wish that she couldn't breathe as she started hearing a sound coming from within the padding. Her eyes were quick to widen again. "Nonononono..." She repeatedly protested as she tried to pull on her older friend's legs, wanting her to stop and help her out... But it was all for naught. She didn't have the strength in her arms, and the dominant T-Doll didn't intend to move even an inch for her sake.

The first wave of the stench came in the form of AK-12's ass rippling with the force of her fart, with the stench immediately causing her nose to flare up and forcibly smell every little speck of that dirty air. She didn't like it at all, making tears run down her cheeks in spades. "S-Stop..." She muttered weakly, but the only response she got in return was another powerful burst of gas causing her hair to ripple outward just a little, and for her tears to stream down her cheeks more intensely...

"How're you holding up down there, AN-94?" The dominant T-Girl asked aloud as she rocked back and forth just a little, grinning from ear to ear like an overly excited child. "I remember when I first started farting in my diapers, it didn't feel too great... Neither did messing them, for that matter. Over time, I really started to appreciate it all. After all, who's going to bother with a diapered girl's messes? They're just going to stare and call it stinky, but they're not going to do anything about it. Even on the battlefield, when I made a mess, nobody batted an eye when they really should've. It's so silly, yet it makes my heart race..."

As soon as she mentioned messing, her stomach started rumbling, making poor AN-94 feel even more anguish. She couldn't stop what came next, no matter how much she'd try to protest or plea. All she could do was just wait for the inevitable...

"Here it comes..." AK-12 gasped as she pushed down as hard as she could, feeling her cheeks redden as the warmth from her favorite activity spread throughout her entire body. She gasped as she felt her anus widen before panting as the first few inches of the serpentine substance slithered its way out of her behind, slowly but surely filling the back of her diaper as it was supposed to do.

The younger girl underneath was completely unable to do anything as the brown parts of the diaper rubbed up against her face, squishing into her cheeks in the process. Thankfully none of the mess actually leaked onto her, but she was not safe at all. The smell, oh goodness the smell. It was so awful that she couldn't even think straight, most of her thoughts being choked out by the awful odor. She wanted to just go away...

But she couldn't go away. there was nowhere for her to go. The only way that she was going to get anywhere, was if she tried to mess her diaper on her own. That lone thought was the only one the stench from her unwanted guest's soiled diaper was unable to squeeze and pop, leaving it to linger inside of her mind. Every second that passed with the stench getting stronger and stronger resulted in the thought dominating more and more of her mind. What had been a desperate attempt to be rational and avoid at least some of her fate turned into a repeated cry running through her mind. "Go poopy. Go poopy! Go Poopy! GO POOPY!" kept loudly playing through her ears, with each repetition becoming more and more unbearable...

Eventually, she couldn't take anymore. The platinum blonde sobbed loudly as she weakly muttered out a few words. "G-Going... Going poopy in my pampers..." AN-94 was defeated, and the way her own diaper quickly filled up in the back showed just how much she had given in. Despite her words, she was actually an impressive little pooper, managing to make a mess that rivaled the one that was currently bearing down on her. If she kept on pushing, maybe she'd even make an even bigger mess than the dominant who had forced her to do this dirty and humiliating act...

Not that she'd need to push, as her eyes widened. The stench had just grabbed ahold of something it never should've, and in turn, she just kept on letting more and more of her pent-up poop slide straight out of her hole. Whether she wanted to or not, it was just pouring out with the intensity of a river, with the solid parts quickly being replaced with softer and squishier bits of poo, until the mess had built up to the point where it was reaching past her knees despite her laying down.

AK-12 couldn't help herself, laughing at the display. "Oops, I think I've gone a little overboard." She chimed as she climbed off her unfortunate target, rubbing her hands together before pushing one of them up against her own mess. "Then again, I knew I had some of the best messes in the entire force. Maybe after we're done here, we should try and get everyone into it. How's that sound, AN-94? My little baby sister?" She chimed so cheerfully even though she had just ruined a fellow T-Doll, obliterating any chance of the girl ever getting out diapers as a result...

AN-94 knew that she didn't have a choice. If she said no, the bigger baby would probably just sit on her again and let her have another taste of her mess. If she said yes, then she'd be strung into helping her make more babies... And... to be honest, the idea of having others that could share in her misery, where all of them could eventually play together like good little baby girls... it made her feel a bit better. So she smiled, for the first time since her big sister came into the room...

Just a few moments ago, there was just one secret baby. Now, there were two, and soon there'd be many more. All of them dependent on their Big Baby Sister, AK-12...
