[Possession/Fusion, Slime TF, Femdom]

“Feels nice to go out on a mission together, huh, Deku?”

The bright-minded Ochako Uraraka smiled from ear to ear as she ran by her friend’s side, the two currently on a rather important mission. Well, important enough for students like them, anyway.

“It does, Uraraka!” The moss-haired boy, Midoriya Izuku alias Deku, chimed with an equally big smile on his face. “I didn’t think we’d get to go in the field any time soon, but to catch a villain that’s recently escaped is a great chance to prove ourselves!” He clenched his fist, ready for anything that it might toss his way.

Of course, that wasn’t the real reason why she was excited. “Mmhm, that’s nice and all. Where do you think he’s hiding? Actually, hold on just a moment.” She grabbed him by the shoulder as they both slowed down, now that her mind had drifted off her brief disappointment. “What exactly are we hunting for again?”

“We’re looking for the villain known as Slimer. A petty crook with a quirk named after his own identity, or vice versa depending on how you look at it. It allows him to melt into a puddle of slime and move around in that state, which gives him incredible avenues for attack and defense. We have to find him fast, otherwise he might try and hide inside somebody. Which…” Deku paused for a second, his face turning briefly green as he imagined the possibility of that, before shaking his head to clear it from his mind. “N-never mind that, we just have to find him.”

Uraraka nodded as she twirled around, trying to see if she could spot anything sticking close to the ground. “Where would you hide if you were a villain, Deku? Maybe that’ll help us find what we’re looking for!” She asked, trying to use her brain based on what he had told her.

“If I were a villain… I would’ve probably ran all the way home to my hideout, but if I was caught off guard…” He mused aloud as he tapped his chin, trying to pinpoint what kind of hiding spot he’d look for in that sort of scenario. “...Can you wait here for a bit, Uraraka? I’ll try and test my theory, you just keep an eye out from here!”

With that, the boy sprinted off, jumping up onto the buildings to get a better view of the area around him. Which left the brunette with nobody to talk to and nobody to lean against. That was fine, she could catch a villain on her own, she had been training for it!

“Right. I had a good idea there, maybe if I put it into practice?” Uraraka thought to herself as she walked into the alleyway closest to her, taking slow deliberate steps as to try and make enough noise that she might attract a villain. You know, because of course those kinds of people hid in shadowed alleyways instead of in deeper crevices. If you could just see villains in an alleyway and call the police ahead of time, they wouldn’t count as villains!

Fortunately for dear Uraraka, she had the right idea. As she stepped over a grate in the alleyway, she swore she could hear some sort of noise right underneath her. Was that what she was looking for? No, it couldn’t be. But it was definitely a sign that somebody was here, so she had to be on her guard.

“Of all the times that somebody would look in here! I mean, somebody was stupid enough to actually check!” The muffled voice of a villain speaking to himself echoed from the grate underneath, his voice being just hushed enough that he couldn’t reveal himself to the person above him. It was the villain that the two youths were looking for, Slimer. And he was forced to adopt a small yet dense and compact form, just to ensure that he wouldn’t be found out.

He had to adopt drastic measures. Instead of hiding away in the sewers where he’d eventually get washed away with the tide and tossed into the sea for everyone to eat away at him, he’d have to do something now. He could hide amongst his peers, even sneak a few bites of snacks and such!

Slimer did what he did best, jumping up and seeping through the grate. The noise was too obvious, and the brunette finally realized that he was underneath her, but it was too late! By reacting to his movement, she left herself wide open. And he knew exactly where he had to go!

“What in thheEEEEE OH GOD!” Uraraka cried out in surprise, which quickly turned into one pained cry of pleasure as the slimy bastard suddenly shot his way straight into her ass. It didn’t matter that she was wearing spats, he was thick enough to pierce straight through and slide into that hidden hole, sinking deeper with every breath she drew until he was nestled nicely and deeply inside of her…

It felt so weird, so awful to have a man squirming around inside her butt. But at the same time, it kinda felt nice. She hadn’t experienced this before, being a virgin and all, but if she could go through it again, maybe she’d try it with something safe. Yeah, that’d be nice to do…

Of course, as she got distracted by the pleasure, the villain realized that he probably shouldn’t have jumped his way into a hormonal teenager’s ass, because it was starting to slurp him further and further in. If he had ever bothered to try and use his quirk to do this more often, he would’ve realized that it had a nasty side effect. Namely, by being absorbed into somebody else, he’d fuse with them and lose himself to their ego while corroding it. The pervertion that the girl was feeling was such an aspect…

Uraraka grinned a little, unaware of her hair starting to drip slime onto the ground below as the rest of her body started losing consistency. She was becoming one with Slimer fast. In fact, the more aroused she grew, the quicker the fusion process. So much so that when she stuck her fingers straight into her pussy, it was like fingering a piece of jello, which initially would’ve confused her… but if anything, it felt really nice to do. Maybe she’d do it just a little more…

Her clothes sunk into her as her body became slimier and slimier, still taking on most of the colors of a proper human while losing most of the solidity. Instead, she just focused on her pleasure. It didn’t matter that she was naked in the middle of the day, she kinda liked rubbing at herself. Especially as the pleasure panged its way through her, making her gasp and pant with a certain need in her eyes.

A need that only a special boy could satiate, a boy who just so happened to land near her as he finally returned. “Uraraka! I couldn’t find Slimer, did you s- ...U-Uraraka?” He gasped, shocked at what he saw. Not only bare breasts, but a horny girl pleasuring herself like that…

“Hah! There you are, Deku!” She giggled with a malicious undertone as she jumped at him, not even a single bit of hesitation in her movements. She just slammed that slimy body down on him, forcing him to the ground as she mounted him. She had plans for him, and she wasn’t about to let him go until those plans were done…

The boy tried to struggle against her, but all he got out of that effort was her ass pushing further into his face, practically suffocating him in the process. It was thick, it was heavy, and most importantly it was sticky. He couldn’t stop her from pushing her holes straight up against his nose and his mouth, leaving him to bury his nose in her asshole and his lips to kiss her pussy, making the fused girl shiver in delight.

“Mmmphhhh… Thaaat’s the spoott… Muuuuch better, especially with you doing it, Deku!” Uraraka giggled and chimed, with every word of hers feeling more malicious than they ever could have. She enjoyed every moment of this, especially as she leaned down on him and used more of her natural weight to keep him pinned. She still had things in mind for him, after all.

Deku couldn’t pry his lips open just by tugging, so he had to push them open with his tongue… Which in turn made him lick the insides of the girl’s pussy, sending a shiver of embarrassment and shame through his body. It was sweet, no doubt caused by the fusion of the villain’s quirk with her body’s natural charm. Even though he never really wanted to taste her, he couldn’t deny that it was tasty, in a weird and twisted kind of way.

“Just keep going, make me feel real good, lover boy…” The corrupted and fused girl licked her lips as she grabbed ahold of his pants, pulling them off his crotch so that she could get to that sweet prize within. A prize that was thick and rigid, ready for her to slobber all over and devour.

A cock the size of her face, the real proof that he was going to be a top hero. Only top heroes had cocks this big, even if his still had plenty of room to grow. Not that it mattered that much that it wasn’t ready yet, she was going to feast on it anyway.

Uraraka didn’t hesitate to slam her tits down on it, capturing it within her slimy cleavage. It was like it was stuck in between the two globs that hung off her chest, while also being stuck inside them both at the same time. The sensation was wild and weird, which just made him want to breathe and speak more… Which in turn made him accidently tongue her further, bringing her arousal higher and higher…

“More… Moreeee!” She cried out as she slammed her slimy tits down on his cock without remorse, intending to milk it for all its worth. She wanted it to cum inside her, she wanted to cum, she wanted him and she wanted him all for herself. Those desires mixed together inside her as she squished the sides of her breasts to the point where he could feel it on both sides of his rod, making him cry out despite his lips being practically stuck to those slimy pussy lips…

That cry wasn’t for show either, as the intensity of her slams forced him to the edge. Globlets of white flooded into her cleavage, while the rest of her jello-like body forced him to stay hard. Especially as it all absorbed its way into her, causing his cock to shiver from the subtle vibrations of her goopy body…

“So good… But that’s not enough!” The villainous Uraraka shouted as she lifted herself off him, switching positions as she freed his lips from her pussy for a brief moment. Before he had a chance to cry out or protest how she was acting, he found himself silenced again, this time between the tits he had just ejaculated inside.

All while she forced her hips down on Deku’s dick, squeezing tightly around it and wringing onto it. She wanted it! Her inner desires were running wild, her cravings running high as her eyes turned into hearts. She craved it, she needed it, and she wouldn’t stop until he had satisfied her completely!

Her hips bounced up and down with the power of a jackhammer, pounding away at his pelvis until he couldn’t take any longer. She had managed to make him cum once, making him cum again wouldn’t be hard at all. Indeed, the globlets of white that had stained her tits quickly flooded into her lower mouth, courtesy of one tired cock being milked despite the near-emptiness of his balls…

The heroic boy wanted it all to be over, but as he looked up past the layers of slime he was stuck in, he could see the need still burning in her eyes. She wasn’t done. And she wouldn’t be done, not by a long shot.

“Keep going, keep going..!” Uraraka cried out, utterly consumed by her own lust. There was no way that she was going to stop any time soon, not until Slimer got removed from her body. And even then, she couldn’t undo what she had done. Not that she might want to, considering it finally broke the proverbial ice between them…

For now, her lust consumed her, driving her to continue. And if she was ever freed, she’d look back on this and laugh...
