[Femdom, Accidental Seduction]

"The Heartless should be around here, right?"

A young Keyblade Wielder, Deltas Nu, had just arrived in the world of Wonderland. He had heard rumors about a powerful and rare Heartless that was causing trouble for those that passed through the world, while not really causing any problems for its inhabitants. It was a rather strange Heartless as a result, but that didn't mean that it could just keep doing what it did. Somebody had to stop it. And that somebody would be him.

With one hand tightly clenched around his Fatal Crest Keyblade, the young man kept going through the confusing paths of Wonderland. Through the mazes, getting bigger and smaller as he tried to figure heads and tails of the environment. All while not spotting the Heartless in the slightest. Where could it be? And what was he looking for, exactly? Was it a Pureblood, like the Neoshadows and the Darkside? Or was it an Emblem that had never been touched?

"Why couldn't it have picked a world that was a lot easier to explore?" Deltas asked himself as he narrowly grabbed onto a ledge and flung himself up onto the corresponding platform, sighing as he kept looking around. He was pretty sure that he had been going in circles. Which wasn't good. If he spent all day looking for the Heartless, then he wouldn't have time to train and hone his skills...

"Ehehehehe..."

A haunting giggle echoed through his ears, prompting Deltas to blink and look around. Where did that sound come from? More importantly, who made that sound? He had to wonder, because he hadn't heard anybody nor seen them. Even the inhabitants that he had stumbled across once, like the Card Soldiers and the White Rabbit were nowhere to be found.

It was then that he saw it. The faintest glimmer of something red. And just as he had seen it, the red flicker vanished. But still, catching a single glimpse was enough. It meant he wasn't looking for nothing!

Deltas ran into another part of Wonderland in pursuit of the thing he saw, relief filling his heart as he saw it once again. And this time, it didn't get away. This time, it was very clear what he had been chasing...

It was definitely a rare Heartless, given the white gown that it wore. A White Mushroom, if he had to make a guess? That was what he assumed anyway, based on the Heartless' red cap and the relatively slim profile when combined with that gown.

"These things really like spells, don't they?" Deltas said to himself, as he spun his Keyblade for a second. Well, he had practiced enough to get the general gist of the basic types of magic. Still needed a bit more training to master each type, but variety was the name of the game here.

The White Mushroom turned around and giggled again, revealing that it wasn't a mere White Mushroom. No White Mushroom that Deltas had ever heard of had hair, much less a clearly female face. Nor did any of them seem particularly amused by the presence of another person...

"...E-Eh?" Deltas was caught a bit off guard by the Heartless' cute face, blushing as she giggled at him. "I-I guess that's why you're so Rare, if you're like that." He did know that Heartless were born from corrupted hearts, especially in the case of Emblem Heartless like this one. But to see them be so overtly humanoid to the point of being feminine... That was definitely new.

The White Mushroom-like Heartless winked at the boy, before suddenly collapsing just like that. Laying down on the ground, as if she had been defeated. Just laying there. Patiently...

Deltas was not prepared for this, but he thought quickly once he saw her laying down. "Right, laying down, that's gotta be healing magic!" He cried out, raising his Keyblade to the sky and letting out some of the magic that he had practiced with. With any luck, this should satisfy her. At least that's what he thought would help, he wasn't quite sure.

The flickers of green healing magic covered the White Mushroom-like Heartless, and she quickly got back on her feet by spinning off the ground and twirling, grinning all the while. She even blew him a kiss for guessing correctly! What a nice Heartless... Or it was trying to lull him into a sense of false security. Either way, she was really cute, that much he couldn't deny.

With a blush on his face, Deltas watched as the feminine Heartless started to fan herself, as sweat quickly started to run down her face. Not only that, but her gown started to get super wet as well, clinging to her form...

Revealing a rather voluptuous body underneath that cloth. Which just made Deltas blush even more. How could a Heartless be this erotic? More importantly, why was she showing him this? What was he supposed to do? Was she trying to seduce him so he'd  lower his guard even further? What was she trying to do? There were so many different thoughts running through his head, all of them making it harder and harder to focus, especially since those breasts of hers were pointed right at his face..!

Closing his eyes and trying to focus, Deltas pointed his Keyblade straight at the curvy Heartless, letting ice fire forth thanks to his ice magic. And just like that, all of her sweat instantly disappeared, and she let out a delightfully relieved moan as she cooled off to the point where she wouldn't have to take off any clothes...

Which she was actually about to do, given the way that her hands were drifting down towards the bottom of her gown. Not that Deltas focused on what she was doing while his eyes were closed. Only when she kissed him again, right on the cheek, did he open his eyes and blush even more than he already had. It was all a bit too much for him, even if this was what he was meant to do. He just hoped that he could manage to keep himself together.

Finally, the White Mushroom-like Heartless started to rub her sides as she started shivering. Part of her body started to get covered in ice. All while she took a few steps towards him. As if she needed something more than fire. It wasn't hard to guess that she wanted fire. It was harder to guess why she was approaching him in a needy way like this..!

Deltas wanted to try and get away, but the sway of her breasts that pushed up against her dress ever slightly, even after it had stopped clinging to her in such an erotic way, was very distracting. Which prompted the cold Heartless to wrap her arms around him and pull him into an extra cold hug..!

"C-Cold! Cold cold cold!" Deltas cried out as he instinctively cast more magic with his Keyblade, sending flames spiraling around him and the Heartless, quickly heating both of them up and washing away any of the cold that still tried to claim them. All so he could quickly catch his breath...

While remaining in her embrace, her breasts still brushing against his face. Which made him turn even redder. It felt really, really good to have her up against him like this. Really... Really...

Deltas' eyes shot open as he realized what he was doing, and he quickly broke away from the Heartless. Sweat ran down his face as his heart beat against his chest. No. All of this was still wrong. He couldn't let himself get pulled in. He couldn't let himself get tricked like this. "Y-You... You've done a lot of bad things to other people, you know! You're not going to trick me..!"

"Trick... Ehehehehe!"

His eyes widened further as she spoke. The Heartless was sentient. More so than any of the ones that he had encountered before. Even more so than the Nobodies that some of the strongest Keyblade Wielders were able to leave behind. This caught him off guard, especially as the Heartless crept closer to him once again.

Only for her to steal a kiss off his lips this time. Pressing those black pillows up against his white lips, really keeping him nice and close to make sure that the kiss was as intimate as it possibly could be. All while he continued to quickly struggle and shake against her grip. It was powerful, and he didn't know how to get free. At least not without her letting go of him...

"Ehehe. Treat." The Heartless chimed, before winking and bowing her heart. "Master!" She chimed, more than happy to call the boy by such a title. He had been such a good boy, after all. A boy that was able to guess through her charades. A boy that hadn't tried to hit her the moment that he laid his eyes upon her. Definitely worth treating as a Master!

Deltas blinked and tried his best not to look straight at her while his embarrassment was at its peak. "M-Master? N-No, Keyblade Wielders can't be a Heartless' Master. You got this all wrong." For that matter, the rumors said that she hadn't done any harm to the ones that she had messed with. Just caused them to leave feeling more tired than-

His eyes widened as he suddenly felt a powerful draining sensation spread through him. Almost as if he had just been sapped. Almost as if every single inch of magic left him. It was... It was..!

"Ehehehe. My treat." The Heartless chimed, as she held up her 'hands' as fire, ice, lightning, time, air, healing and gravity all briefly shifted above those 'hands'. Showing that she had temporarily stripped him of his power. So that she could use it in turn. "Master tasty. Master fun?" She said such simple words, but she was making good use of them. Really illustrating how much fun she was having. And how much fun she wished to have with the boy that had come to try and stop her.

Deltas could feel his nethers trembling as his eyes dimmed slightly. He gasped and he panted, as he grew remarkably calm. All while he gently sniffed the air. He hadn't been through this before, even though he knew that this could happen. His lack of magic resonated with the Fatal Crest he held...

And the Heartless certainly noticed as well. She could see the ferocious look in her eyes. That delightful look that she liked a whole lot. It was almost like he was a Heartless, that's what he looked like right now. And she knew exactly how she was going to take advantage of it. How she could make him feel even better. He was her Master, after all!

The devious Heartless grabbed ahold of her gown, and lifted it up. Revealing her pure black body, and the tender meat that served as her body. Her generously hefty breasts that were almost as big as her head, and her hips that were just begging to be grabbed by a ferocious boy like the one that she had managed to hook in. She was even dripping a little down below, which brought the boy's attention towards the Emblem that served as her womb tattoo...

Deltas took in the Heartless' body. Really let that figure soak in. And his cock just kept on trembling, right up until the moment it burst from his pants, and he couldn't take it any longer. It didn't matter if he wasn't supposed to mate with a Heartless. It didn't matter that he had fallen prey to her tricks. Right now, the only thing that mattered was his overwhelming arousal. He wanted to cum, and he wasn't going to stop no matter what tried to get in his way!

The young man practically leapt at the Heartless, who let her gown fall down on him. Obscuring him from the wider world, all while she felt him wrap around her. If somebody were to look at the two from the outside, it would be hard to tell exactly what was happening. Only that she had a bit of girth.

When in reality, Deltas had latched onto her and clung to her like a monkey. All while making sure to keep his grip nice and tight as he slammed straight into her. It was quite the feat that allowed him to keep his position, and it was also quite the feat that allowed him to fuck her like this. But he didn't focus on any of that. He barely even had any focus. All he had was a berserker's lust, brought to him by his Keyblade's special ability.

The Heartless really liked how it felt to be fucked by her Master. She had never really experienced this kind of fuck, because all of the other Masters that she had tried to make were all far too easy to break. None of them even guessed all three correctly, so she drained them of every single bit of their Mana and anything else they might have. That was how she had amassed her very interesting reputation.

But this Master? He was so different! He was actually really into this! It surprised her, but she wasn't about to say it was a bad thing at all! It was a very great thing to have him try to fuck her like this! She wanted him to keep going for as long as he possibly could, so she would be bred until she couldn't stand! That would be the best!

Deltas could feel the Heartless growing tighter in response to his thrusts, and just thrust harder. The only thing he responded to at the moment was physical stimuli. Whether it was the Heartless hugging him and pulling him even closer which prompted him to fuck her harder, or her body heating up which made it even easier to thrust harder. Everything he did was simply to reach the greatest peaks of pleasure. Everything!

If his fellow Keyblade Wielders saw him now. If they saw him mating with a Heartless that called him Master... He would be laughed at. Or worse than that, they would consider him a heretic. But he didn't care. Right now, the only thing that mattered was pleasure. He'd work out the details after that, after he managed to pull himself back to the edge of sensibility.

The Heartless kept on moaning more and more as he kept jackhammering into her. It was incredible. It was so intense that she was about to lose all control of herself. In fact, that's exactly what happened. She couldn't stay standing, because the boy had managed to screw her so hard that her legs gave way. Resulting in her ending up on her back, all while she continued to get screwed by the boy that she had lured in with her charades and her lusty body...

Now that he was on top of her, it was a lot easier to go at her. Nothing really stopped him from pounding as hard as he possibly could or as fast as he could. Thrusting in and out as he moaned over and over and over. A true berserker, currently proving himself as a paradox. He was like this because he had lost all of his mana and activated his Keyblade's ability, yet he'd have to empty his balls as he ended up recharging before he'd regain himself...

Not that his partner really had any complaints. She loved every moment of it. She loved having him thrust into her this quickly and this potently. It felt good to get rammed into. It felt good to be used by Master. She loved it. She looooved it. She wanted more and more. All so she could climb over the edge. Reach that climax, and enjoy herself with her Master..!

Moans from both of them kept on bouncing all around, until it became far too much for both of them to endure. Whether it was the Heartless or the boy that had been charmed by her, neither of them were able to handle any more. They both came at the same time, and let it all loose. Whether it was the juices flooding out of the Heartless' thoroughly pounded pussy, or the cum that splattered all around inside of her hole...

Deltas was returned to lucidity as he seeded the Heartless' womb, panting and gasping and sweating from being stuck underneath that gown. All while he tried to properly understand what had happened. The last he remembered, he had been kissed by the Heartless. And then it all just kind of went red and he didn't remember a thing...

"Master..!" But the Heartless that he was still buried inside was more than happy to catch him up to speed, hugging him against her body as she rubbed the back of his head. Giggling as she made sure to rub him lots and lots and lots. She loved him a lot. Which was evident by her Emblem right above her pussy changing into a Golden heart instead. Not quite an emblem that matched anything besides the boy's hair, but it was good enough for her.

Deltas, meanwhile, couldn't help but blush as he realized what had happened. "I... I fucked a Heartless..." He muttered in sheer shock. What was he going to say to his fellow Wielders? More importantly, what was going to happen in there? It was a question that he had no real answer for, and he was sure that he wasn't going to get an answer any time soon.

So, he just sighed and hugged and snuggled the Heartless as she snuggled him back. If he let himself be consumed by his worries, if he let himself worry far too much about what could happen instead of what was happening, then he would just end up losing himself. So better to just enjoy things now...

"Ehehehe. Master. Moooore..."

Not realizing that his new 'pet' had some devious ideas in mind, ones that would leave him with a growing harem sooner rather than later...
