[ABDL, Sadism, Enema, Soiling]

"Ehehehehe... Can't we stay here and watch? I wanna see her break..."

"Lady Aquitia would break you too if we stayed here. Let's just strap her in. We'll get to spend a lot of time with her soon, once she's one of us."

Two Monster Girls were chatting amongst themselves, as they strapped a human to a chair. A human that was covered in bruises and other small bits of damage, though she refused to show any weakness in the face of defeat. She knew better than that...

The adventurer that was currently bound to the chair had black hair that reached part way down her back, with two tufts bound by a ribbon that made her look like she had a pair of cat ears. She wore a tight gray bodysuit with gray armor on top, with the armor mostly placed on her lower legs and her upper body. Mainly serving to protect her when she needed to guard, as her acrobatics would help her dodge out of the way of any fatal attacks. Not that her armor was in any condition to defend her at this point.

Her name was Katina Schwarz. An Adventurer that hailed from the southern region of Nusantara, more specifically the quiet seaside town of Dewdrop Vale. She was the best that the town had to offer, and their pride and joy. So when the Demon Lord of Nusantara struck to try and conquer the region and claim more for herself, Katina did everything she could to try and save her fellow townsfolk and take out as many Monster Girls as she could.

While she ultimately failed to escape herself, she saw many get the chance to live another day. And that was enough for her. Now all she could do was endure the torture that came her way. Due to her status as one of Dewdrop Vale's best, she had been in contact with fellow adventurers and defenders. Allowing her more insight into the way that the Demon Lords of the world operated. How they dismantled the world and claimed one piece as their own, all so they could torment the humans that had once been in the majority...

Indeed. This world, Fantasmagorie, had once been a world dominated by Humanity. But one day, Monsters started to rise. Their attack was fast, with many parts of Humanity left completely defenseless. Carving the world into eight pieces. The center, Lagrimosa, served as the only home for Humanity, with the seven other regions each claimed by a different Demon Lord.

Nusantara's Demon Lord, and the one that Katina had personally faced in combat, was the Lady of the Deep, Ralette. A massive Mermaid that manipulated the waves to drown her town. Those that were not drowned by her waves fell when her forces assaulted the waterlogged town. Katina was not the only one that had been captured, yet she suspected that many of the girls she had fought against would break far before she would...

"Ara. You two are still here? You know what I do to naughty girls that try to watch me work."

The two Monster Girls that had bound Katina to the chair each felt shivers run down their back as a dominant presence made her way into this containment room. And before the bound human had the chance to stare towards the source of the voice, the two girls had already fled. Leaving her all alone with this new presence...

Katina gazed upon her. The blue-haired Sea Dragon that she had fought back in Dewdrop Vale. One of Ralette's greatest generals. She had tried her best to fight against her, but her arrows and her grit weren't enough. Even her last trick hadn't worked, as the arrow aimed straight at the Sea Dragon's eye had been crushed and swallowed by the waters that were at her command...

If they were in a more peaceful time, she might've appreciated the way that the Sea Dragon was dressed. The black cloth that was connected to her blue dress, bringing extra emphasis to her breasts, as well as her detached sleeves bringing additional emphasis to her naked shoulders really brought one's gaze upward. But she still left plenty of delight to gaze upon down below, as her dress was parted on the left side to allow for her thigh to poke out, and her stockings clung so lovingly to her lower thigh as well, those white-and-blue garments reaching down to her elegant heels. Her beautiful and arguably erotic appearance was only undercut by her Monster features, namely her tail and her two blue horns. None really spoke about those, compared to the rumors of this woman's more appealing features...

"We meet again, Human." The Sea Dragon's voice was practically dripping with venom as she addressed the girl, especially as she placed a glove-covered finger right underneath her chin, lifting her head up so they could look into each other's eyes. "I trust you've taken the time to soak in your defeat? Knowing that there was absolutely nothing you could do to stand up against our might?"

Katina didn't respond, keeping her eyes from meeting the Sea Dragon's. Which just made the woman chuckle in turn. "My. You think you can resist. How utterly adorable." There was just something about Humans thinking they had a chance to stand against them that brought no end of joy to her. Ah... She was going to enjoy this a lot.

"But where are my manners? I am Aquitia, and it is my duty to make sure that you go through all the necessary steps to become one of the Demon Lord's toys." She said, before letting her head dive forward, stealing a kiss right off Katina's lips.

Katina's eyes widened as she was kissed, prompting her to try and pull her head back. But it was all for naught. Her first kiss had been stolen by this horrid Monster Girl, who was taking far too much glee in all of this. Especially the subtle anger working its way onto the Human's face. "You... You won't get away with this..."

"Oh, but I will." Aquitia giggled, as she gently rubbed her thumb up against Katina's bruised cheek. It was a shame that she had been damaged in such a way. But every toy would be fixed in time. Her mind had to go first, however. "You really think you can stand against us? Stand against the Demon Lord, after you've failed to defend your town? You make me laugh, Human. You really don't understand. But don't worry. I'll help you understand."

"What is there to understand, when you won't be able to break me?" Katina shot back, her voice calming down. She had to remain calm. That was the only way she would be able to claim victory. Even if she had to endure so much, she had to hold out. Waste their time, so that others could eventually mount a counter-offensive..."

Aquitia did her best to stifle a laugh, only to break out into hysterics. "Those girls that guided you in here were much like you. They thought they could endure. But they broke. Just as you will." She chimed, before reaching into her dress, and pulling forth a rather degrading looking garment that she had kept attached to her hip. Kept hidden, just so she could see the look on Katina's face.

And it was a delightfully terrified one. Katina thought that she would just be hurt. Pain was something she had grown used to. But the garment that Aquitia held wasn't one made for pain. It was made for pure humiliation. A garment that she hadn't worn in ages...

It was a diaper. A big, white, crinkly diaper. Made for infants. Made for humiliating adults like her. She could already picture it... All because of what she had heard. She didn't truly believe the stories, but now... Oh, oh gods above...

"Ohoho. That look on your face. And here I thought you didn't know." Aquitia giggled, as she pushed the diaper up against Katina's face. Letting the crinkle run through her ears. "Your fate, as well as the fate of any other strong Human that ends up in our possession... is to be turned into a diaper slave. The Demon Lord does love to see such strong souls made into such humiliated girls. Filling these all day in, all day out. Unable to do anything except push more and more mush into their seats... Ehehehehe!"

"S-Stop it..!" Katina didn't want to think about it. She didn't even want to entertain it. But the images were already flooding into her mind. Not just of her, but of her fellow townsfolk being made to fill diapers for years. Broken, crying their hearts out as they just keep filling. She didn't want to imagine it. But her imagination was vivid. She had to curse herself, because this kind of vivid imagination was due to her own image training to make herself a better archer. Because she could picture her targets in her mind, she could also picture her own demise...

She wanted to stop it herself. And she did manage to force herself to break free from one binding, her arm snapping the flimsy ropes that kept her arm pinned to the chair's armrest. Only for Aquitia to grab ahold of her, keeping a tight grip on her throat to make sure that she wouldn't be able to do anything.

The feeling of being short of air was familiar. Just like when the town had been drowned. And seeing her struggling like this was utterly delightful to Aquitia. Ah... If only she wasn't tasked with breaking this girl right now. She'd have a lot of fun herself. But she had to finish. Only then could she go have fun with herself until the next step...

With her strength, and her grip keeping Katina from doing much, it was easy to strip Katina. Armor and cloth hitting the ground, until the poor girl was left completely naked. Naked, and defenseless against whatever the Sea Dragon had planned...

Aquitia forced Katina onto the ground, and forced the humiliating garment onto her. Keeping her grip on her as she slid the diaper underneath her, and then forced it through her thighs so she could snap it shut. Even making sure that it was properly sealed, so that she couldn't try to force it off her on her own.

"There. Isn't that so much better? Now you look as strong as you truly are." The Sea Dragon giggled as she finally let go of Katina, who sharply inhaled now that she had access to more air again. All while the devious Monster Girl continued to mockingly leer at her. Far too entertained by all of this. Far too amused by all of this. She was the very worst. Even worse than the Demon Lord. Even if the Demon Lord had been responsible for destroying her town, Aquitia was far more sadistic...

Katina glared up at the Sea Dragon, as she tried to get away. She couldn't do much, beyond simply trying to crawl. And even that didn't let her get far, before she was gently kicked in the side. Even a gentle kick like that hurt when it came from somebody as powerful as Aquitia, causing her to let out a groan as she was forced onto her stomach...

"Still trying to get away. Even when you know it's hopeless." Aquitia chimed, gently patting the girl's rear. "You are the naughtiest girl I've ever seen. Truly the very worst. But that's okay. I know how to discipline girls like you." She giggled, her tone sounding even more sadistic than before. She had something horrifying in mind, it was easy to tell.

Especially as she grabbed ahold of Katina with one arm, and stuffed another down the back of her diaper. The human could feel that wet hand sliding along her rear, before a thick wet finger forced its way into her hole. Forcibly spreading apart her anus in such a painful manner, causing her to cry out in pain once again.

But the insertion wasn't the bad part. The bad part was what came next. The jet of water that shot into her bowels, flooding her within seconds. And immediately, the cramps started up. She needed to get it all out of her system, and her hands were forced to clutch her belly to try and stop it... Only for her weakened body to give up, causing her arms to end up at her sides. The internal pain of being given an enema combined with the pain from when she fought against the Demon Lord to try and save everyone was far too much for her...

"Ehe. That's so much better." Aquitia chimed. "Humans like you deserve no mercy. No quarter, for everything you've done. You all deserve to be our playthings... And once you break, you can have fun breaking other Humans as well. That's the privilege of becoming a Monster Girl, ehehe..."

Katina trembled as she felt that finger finally get taken out. But she wasn't blessed with the faintest sense of relief. No. She could feel ice inside her butt. Thick ice that kept her stuffed. Ice that plugged her up and kept her from making any messes...

"You should enjoy these last few moments of continence, Human. Because once that ice melts, so will your continence. You'll never be able to keep your butt closed. Always forced to empty everything into your diaper. And every mess you make will make you sink further and further. Doesn't that sound just delightful? Ehehe!" Aquitia was enjoying all of this far too much. How couldn't she? Seeing a human break never got old!

Katina didn't want this. Of course she didn't. There's no way that she would want something like this. But all she could do was weakly try to keep it in her. She tried her best to fight back against the sensations inside her... But her body had been weakened so much that even the act of struggling just made it worse, as she felt the ice in her ass slowly melt.

"P-Plea-"

She didn't even get the chance to finish begging for help, before she felt the ice melt just enough that the twitching of her ass managed to shatter the small amount that still remained. And as soon as that blockage was undone, the unholy filth that had built up thanks to Aquitia's actions started to flood out.

So much runny filth, pure sludge, flooded its way out of her hole. Despite the pain that came from feeling it all run out of her, despite the humiliation, Katina did her best to stay strong. But as she felt the weight pulling her further and further down, preventing her from getting back up, her heart started to waver.

This... This was to be her fate. It finally sank in. The fact that she would do this. Over and over and over. Even if she managed to escape, she'd be left diaper dependent. She wouldn't ever be able to just go to the toilet and take her time ever again. She could shit herself at any point, and she wouldn't realize it until it was far too late...

Aquitia giggled as she watched pure despair dawn on Katina's face, and the first few tears started to roll down her cheeks. Ah. She loved this so much. When they realized that there was no way that they could escape. When they realized that their only fate was to keep filling their diapers. Until they broke completely, and loved every single moment of it...

"You should get used to it, Human." Aquitia chimed as she put one hand on Katina's messy diaper before pushing that hand down, letting the disgusting noises echo out while her grin grew even larger. "You want to endure, don't you? Then this should be nothing within, oh, a week? After all, this is just one mess. You'll be making so many more, and if this is all it takes to make you cry... Then you're going to break even earlier than I expected, ehehehe!"

Katina couldn't really muster up any kind of defense, as the pain of soiling herself this badly was too much. All she could do was stare ahead, consumed by her own fears...

All as Aquitia introduced her to the displeasing sensation of being spanked, reddening her butt for the first very first time...

---

"Ow... Ow..."

Kalina muttered to herself as she slowly rubbed her butt, the sound of her fresh diaper crinkling as she tried to deal with the pain that lingered after she got spanked. Aquitia had spanked her so thoroughly that her butt was still throbbing way after the fact, especially since she had done it while her diaper was off as well...

Even though she was lying in a crib and was finally alone, that lingering sting just made it all worse. As she was left to dwell on her future. And the fact that she was destined to be a diaper slave... Worse, a Monster Girl if she were to break completely...

To tell the truth, she wasn't sure if she was going to be able to handle it. Especially not after she had been forced to dress in her bodysuit again, which was a lot more revealing now that she didn't have any armor to cover the more naughty parts with. Even if her diaper covered up her nethers.

The only way she could keep herself together was if she could escape. But with the Demon Lord, and Aquitia's own watery abilities, getting back to the shore seemed impossible...

Katina trembled as she felt her stomach rumbling, and she just closed her eyes. Not even bothering to put up resistance as the seat of her diaper filled out with fresh filth. All while thinking about her fate...

Just how long could she last, and how much worse could it all get..?
