[ABDL, Diaper Use, Soiling, Enema]

“Hmmmm. Hmmmmm…. Hmmmmmmmm…”

“Nope. Can’t do it. Haaaaah…”

The tired and slightly frustrated voice of a young girl echoed through her personal studio as she slumped over her tablet, a bit of steam rising out of her head. This hadn’t been the first time she ended up in a mood where she just couldn’t turn her thoughts into art, but it was starting to become a problem.

The young artist was named Langshi. A girl with boundless imagination, to the point where she had managed to create so many worlds of her own design. Each of them built up using both her art and her writing skills, leading to many of her creations finding life of their own.

But those skills came at a price. By making so many worlds, and having to keep an eye on a semi-frequent basis despite having made a guardian to do the job for her… She more than often ended up quite tired by the time she felt the urge to create more. Leading her into a rut of creativity that she hadn’t managed to climb out of just yet.

Langshi put down her pen and slowly got up from her chair. For now, she was just going to grab herself something to drink. Something to distract herself with.

Not a moment after leaving her studio, however, she noticed that something was very off. Namely because she had wandered straight out of a room that had been specifically designed to give her the best work environment for both of her skills…

Into what could best be described as a pastel-colored nursery. The type that the babies she enjoyed bullying usually ended up in. Not unlike the one hidden deep within Maidens’ Dream, where plenty of the boat girls that she once commissioned found their fate as adorably poopy babies.

Besides herself, there was only one person besides herself that had an ability to toy with her abode. And that very same person loved this kind of setting more than she did.

The Lady of the Lunar Sea. More affectionately known as Chang Yi. Though despite knowing that she was the culprit, that very same little lady wasn’t anywhere to be seen.

“Chang Yi? If you want to play with me, you just have to ask. Please don’t mess around with the Lunar Palace while I’m inside.” Langshi said aloud as she looked around the nursery a little bit more, idly taking a few steps forward.

Ah, just being in here was getting her in a mood. One of her more dominant moods too. She could just imagine a cute baby on the verge of messing her diaper, her sphincter going loose as a torrent of cute toots and *frrrts* echoed forth from her butt.

...Wait, no, that wasn’t her imagination. Not that last part.

Langshi turned around, and laid her eyes upon a blushing black-haired girl standing near the exit to the nursery. A girl wearing a kimono with detached sleeves and a see-through skirt that exposed a garment that had already started crinkling the second the other girl looked at her.

“S-Sorry, Nee-sama.” The girl, Chang Yi herself, smiled as softly as she could. Despite the trick she had played on her sister-slash-creator, she was anything but a tricky soul at heart. She was a girl who just wanted to spend lots and lots of time with her. But since she couldn’t bring herself to interrupt her when she was working, this was the only solution she could come up with. “I-I just wanted to… to…”

Langshi sighed a little before smiling and placing a hand on her diapered ‘little sister’. “I couldn’t get mad at you, Chang Yi. Not when you’re the most adorable little sister a girl could ask for.” She chimed, while using one of her hands to grope the front of the girl’s diaper. “Especially when you know to wear a diaper before you come visit me.”

“E-Ehehe…” Chang Yi giggled a little herself, fidgeting as she pulled at the ends of her kimono. “It’s not just because I wanted to make you happy, Nee-sama. It’s because it’s… It’s your birthday! A-And I wanted to surprise you a little!”

...Ah. That would explain a lot, actually. She noticed that her phone pinged her a little early in the morning, but she didn’t bother checking.

Langshi’s smile grew as she lifted her hand off her sister’s head and used that very same hand to hug the girl closer to her. While pushing her other hand into her diaper with a bit more vigor. Just to get a feel for how thick it was, and to tease her all the same. “Thank you, Chang Yi. I couldn’t ask for a better sister.”

“No, Nee-sama. Thank you for being the perfect elder sister!” Chang Yi cried out in delight, squirming as the front of her diaper started growing more than a little wet. Being touched like this and having the affection poured into her by the girl that she loved… Ah, it was too much for somebody like her.

But that wasn’t why she had gone through all the trouble of preparing this nursery. “By the way, Nee-sama. You’ve always wanted a really good birthday gift, right?”

Langshi nodded a little, before the girl disappeared from her arms. Turning around, she saw the girl obediently laying down on a cute blanket covered with cartoonish depictions of the creator’s own creations, her diaper on full display.

It didn’t take a genius to understand what this was meant to imply. This was the birthday gift that her little sister had in mind for her. An adorable experience with her as her older sister’s loving little baby. Just like the many girls that she had created before that deserved to be babied, except she had prepared everything the older girl might need. Whether it was a little bucket full of liquid for an enema, extra diapers to make sure she could mess them all… And the blanket itself would ensure she didn’t spill anything too violently.

“If I didn’t know any better, Chang Yi…” Langshi said as she stepped closer to the resting baby, her smile turning into a bit of a dominant grin. “I’d think that you had been waiting ages for this day, because you’ve always wanted to be my little baby girl.” This was exactly what she had been craving. And considering that the little baby had once been nothing more than thoughts inside the creator’s head, it wasn’t impossible to guess that this was indeed all planned from the very start.

Chang Yi nervously shivered. But it was easy to tell that it was all faked. She loved this kind of scenario too much. It was one that they had both gone through quite a few times. But never like this. Never with the little sister just letting all the gear sit out for her older sister to use at her leisure…

Langshi took her silence as a seal of approval, as she reached for the little tube she’d use for the enema. She let it rest in the bucket for a brief moment as she undid the tapes on her little sister’s diaper, exposing the naughty bits hidden underneath.

Her adorable little sister covered her face in feigned embarrassment, trying to squeeze her legs together to hide away her pussy. But it wasn’t what her Nee-sama was trying to reach either way. What she was aiming for was the hole behind it, the hole that was still quietly tooting away. Even letting out an informal and rather rude *Brrraaap* right before Langshi slid the tube into her rear.

“You really went all out with this…” Langshi muttered. Even though she could smell the stink from her little baby girl on her hand, the fact she was uncontrollably letting it all out was enough to make the older sister’s nethers grow wetter by the second. Ah, she really loved this show of desperation.

The receiving end of the tube went into Chang Yi’s butt, and the girl naturally started squirming. Even though she had been given an enema several hundred times at this point, she never quite got used to the cold instrument sliding into her. She couldn’t even say she particularly enjoyed it either, it always just made her shiver and whimper.

Langshi watched as her little sister’s adorably tight hole kept trying to push out the gas within her. Leading to muffled and almost whistle-like *pfffts*. It also wasn’t nearly as stinky as a result, but it was still the sheer desperation that mattered more.

She grasped the instrument tight and squeezed it, as one end of the tube sucked up the liquid in the bucket, before letting go and watching it quickly pour into the gassy hole due to the change in pressure.

The more she did it, the more she could see her little sister squirming. She knew how good it felt to have that liquid sloshing around inside her colon. Rubbing up against all those sensitive spots. And the further in it got, the easier it’d be to get through the next part.

Langshi was familiar with the specific bucket that Chang Yi had prepared for her. That liquid wasn’t water. It was a milky liquid that acted as a sort of aphrodisiac. And while it would certainly help them get all nice and heated, that same arousal that would be pouring through her little sister would also help her get nice and loose when it was time to push things out.

The best part about it? It was devilishly quick. To the point where she could already hear the faint groans from her sister’s lips as she trembled more and more. Her stomach was throwing a fit, and the pressure inside her was building. Those groans were just as accompanied by moans, because of the aphrodisiac working as intended.

Once the older sister thought her little sister had endured enough of this treatment, she rather roughly yanked out the tool, letting a violent and humiliating *BRAAAAAP* leave the younger sister’s thoroughly filled hole. Even a few droplets of the liquid poured out of her hole from the sudden change in pressure.

Chang Yi was panting and gasping as she tried to keep herself from making a mess. She shouldn’t be making a mess, not like this. Not without her diaper on. Only once she felt those tapes shutting around her waist, and that dangerous thickness keeping her from closing her legs, she knew that could just relax and let herself be taken by her needs.

*FRRRRRRT*

The last fart that left her hole was a loud one. So loud that it even managed to make the diaper crinkle a little from the sheer force of the humiliating act. But it was merely the signal that heralded in an even more degrading act.

Langshi watched as her little sister let out a loud moan, before the disgusting wet sounds of her diaper being filled with a smelly sludge echoed through the nursery. The sounds were rather violent too, as a result of giving her quite the intense enema.

She loved it. Watching that pristine diaper grow brown in a matter of seconds, turning the entire garment soggy as the liquid parts of the mess were being soaked up by the diaper. It was too enthralling to watch, to the point where the older sister couldn’t help herself as she very nearly mounted her younger sister.

Chang Yi’s moans grew even louder as her older sister’s hand found its way onto her butt. It was such a dirty surface, but she pushed on it more and more. Forcing the liquid mess to spread around inside the diaper. Covering more and more of her terribly sensitive body.

To say that she had messed herself would now be a gross understatement. Her diaper had soaked up so much of that poopy water that it barely even crinkled, it more just started leaking some of that dirty water onto the blanket below. Not to mention the slight bits of poop trying to escape her legholes.

“What a dirty, dirty little baby you are, Chang Yi…” Langshi whispered into her younger sister’s ear as she reached for one of the other diapers. It didn’t matter what it was covered in, it would probably end up just as dirty as her younger sister’s current diaper within a few moments.

There was no way that she was giving her little sister a change. All that she’d get right now was an extra layer, to keep her a little dry. And adding a layer to a dirty baby was easy, because her legs were already spread apart. Just lifting her up to align the back with the butt, and then weaving and snapping the rest shut so it could contain everything was all that it took.

Even though Chang Yi was now a little more protected, it didn’t stop her from filling her diaper more and more. This extra layer would just keep her from leaking onto the ground below. It didn’t really keep her clean at all… Which was exactly the kind of humiliating experience that she loved. Just taking a breath was making her squirm more as she felt her poor butt pushing out more and more.

All while her dearest Nee-sama was pressing her hand against her diaper. Mushing and pushing away at her mess, while also using one of her hands to pinch away at her nipples after sneaking it into her top. She was such a naughty girl for getting turned on by this.

But it was exactly what she always wanted. And what she always wanted to give her older sister. An experience that she could never forget. An experience she would never want to forget. The best baby play that she could offer her…

Langshi was pressing her thighs together the more she played with her little baby sister’s body. This was so hot. Seeing that desperation on the younger girl’s face, and the way she just couldn’t stop herself. Seeing her cumming and pooping again and again and again…

Just playing with her for long enough was too much for the creator. She collapsed on top of her little sister, squirming and panting as she made a complete mess of her own undergarments, her slick feminine juices drooling out through the fabric of her panties. Great, now she needed a diaper too…

As the two sisters, exhausted by their respective climaxes, just kept still for a few moments… The elder finally whispered into her younger sister’s ear, cutting past the veil. “You’ve been enjoying this since the moment we started, haven’t you, Chang Yi?”

“M-Mmhm. I’ve loved every moment of it, Nee-sama…” The submissive baby, who let out another little cry of pleasure from her hole slowly but surely drying up despite the small pond’s worth of poopy loaded into the back of her diaper, couldn’t stop herself from letting her ‘secret’ out.

And once she did, she received a loving kiss on her lips, and a smile from her older sister. “Thank you, Chang Yi. Thank you so much for this. It was exactly what I needed…” She wasn’t kidding either. Having this much fun was bound to make it easier to turn her thoughts into images and words once she recovered from the afterglow.

Chang Yi smiled as she heard those wonderful words. And she whispered a few of her own back to the girl that had made her and loved her as her own flesh and blood, before closing her eyes and allowing the afterglow to overwhelm her thoroughly pooped mind as she drifted into a warm nap.

“I love you, Nee-sama. Happy birthday.”
