Themes: Breeding, Fucked Silly, Titplay

Summary: Izuku should have known better than to accept a drink from Mei Hatsume of all people. Especially when it's another of her experiments. When he wakes up the next morning in a fancy hotel room in the city with Mina, Momo, and Mei all thoroughly fucked silly and stuffed full of his cum, he initially freaks out. But as it turns out, they all wanted it... and they aren't done with him yet. 

-x-X-x-

As Izuku Midoriya slowly begins to wake up, he does so with a groan. His head hurts… but surprisingly, the ache goes away quite fast. He’s pretty sure he should have a hangover right now. But… why should he have a hangover again? Ah, that’s right. The last thing he remembered was Mei Hatsume of all people offering him a drink. That he’d taken and drank. Yeah, not his brightest move.

Still, at least it seemed to be clearing out of his head really fast. How long had it been anyways? Blinking, Izuku stares up at a ceiling he doesn’t recognize, belatedly realizing several things. One, he’s on a bed. He wasn’t on a bed when he drank Mei’s drink, obviously. Two, he’s naked. He also wasn’t naked, when he drank the drink.

Three, there’s a weird weight on his lower legs that is NOT the feeling of bedsheets or blankets. It’s a bit too… fleshy for that. Suddenly dreading what he’s about to find, Izuku nevertheless slowly lifts his head and takes in the room.

Part of him blearily recognizes that this is a hotel room. Not just a hotel room, but an entire hotel SUITE. The big, expansive space is utterly trashed… but more than that, Izuku isn’t alone. There are three women in the room with him. One of them, the furthest away, is the most recognizable, even if he can’t currently see her face. But her pink skin makes it impossible to misidentify her.

Mina Ashido lies bent over the couch, her upper half currently out of Izuku’s field of view. Her completely naked lower half on the other hand, is giving him an eyeful, and he can see the white, sticky substance stuffing her naked, fucked cunt from the bed. Unfortunately, she’s not the only one. On the actual bed with him, laid out to the side with her limbs sprawling in every direction, is Momo Yaoyorozu. The beautiful, raven-haired heiress is just as naked as Mina… and just as creampied, her chest slowly rising and falling with every breath she takes, even as jizz leaks out of her.

And then there’s the third and final member of this entire kerfuffle. He can’t see her face either, but he… well, he sort of recognizes her ass anyways? Izuku blushes, as he looks down the length of his body, where Mei Hatsume’s sizable derriere is about a foot away from his rising cock. Her legs spread in a perfect split, her pussy is just as cream-filled as the other two, even as she lays there, equally passed out and fucked silly.

The weight he’d felt on his legs were from her thighs, spread perpendicular across his lower appendages. Izuku’s mouth opens and closes as he takes this all in, his body responding naturally to the sight and smell and… and everything else by betraying him and growing aroused. His erection would do him no favors here, he was pretty sure.

… He didn’t know what to do. Maybe he could sneak away? No… no, he couldn’t do that. He had to face the music. He’d done this, even if Mei’s drink had been the culprit, he’d still done all of this in the heat of whatever the fuck happened last night. He couldn’t just run away.

Still, he does try to extricate himself out from under Mei’s legs so he can get up without waking her. Unfortunately, he’s not as stealthy as he wants to be.

“Wha-?! I’m up! I-! … Oh.”

Mei comes up with an arch of her back, blinking rapidly and looking around the room for a moment before noticing Momo and Mina. Then she notices Izuku’s feet and the fact that she’s doing the splits on his legs, and glances back over her shoulder to see him and his traitorous cock laying there, trying to get out from under her. Not that he’s trying anymore… cat’s out of the bag now.

And to pile it on even further, Mei’s exclamation has the effect of waking Mina and Momo up as well. As the two of them are slowly coming to, Izuku can only blush as the incredibly smart support gear engineer that he apparently fucked silly the night before, grins and spins about. A moment later, her naked tits are slid into place around his cock, her hands working her incredibly soft boobs up and down his shaft as Izuku tosses his head back in an involuntary groan.

“Heh, like that ‘Zuku? Yeah, you sure did last night, so I figured you would…”

Panting, clawing at the bedding beneath him and trying not to blow his load all over Mei’s face and tits immediately, Izuku grimaces as he looks down at the girl.

“Mei… what happened?”

Before Mei can do more than open her mouth, another one of the girls in the room clears her throat and pipes up.

“… I can answer that.”

Izuku looks over and is struck by how beautiful Momo looks, kneeling there on the bed, having sat up. She has one arm crossed under her tits to grab at her other arm and is looking rather embarrassed… but also throwing hungry glances at his cock. Mina isn’t doing much better, the pink-skinned young woman having crawled off of the couch and over to the bed now.

“Things got a little crazy after you tried Mei’s experiment. You, uh… finally let yourself be free with your feelings for the three of us and we… we didn’t exactly discourage it.”

Momo blushes and glances to the side, biting her lower lip as if remembering the night before fondly. Izuku blushes even harder as she squirms and rubs her already creampied cunt against the bed beneath her in remembrance. Sheesh, was he that good? At least this was letting him distract himself from Mei’s efforts. He was still minutes at best from cumming, however.

“I didn’t… I didn’t force myself on any of you, did I?”

Mina is the one who pipes up at that, her alien eyes going wide.

“What?! No! We’re all just as interested in you as you are in us! If it weren’t for Ms. Responsible here, we’d all be Miss Midoriya’s now!”

Izuku’s eyes widen at that, and for the first time he notices the rings. He has a ring on… and so do all three girls. Right where the wedding bands would go. Momo notices his panic and immediately seeks to assuage his fears.

“I-It’s not what you think! They’re engagement rings! We’re, uh… we’re fiancés now, the f-four of us. In your… uninhibited state, you wanted to go further faster, but I suppose I was the voice of reason. These two would have gone along with it, but I wanted you to be in your right mind when you took me… ahem, took us to the altar.”

Mina just sighs and shrugs.

“It makes sense, I suppose. This way, we can have a proper wedding. Still! You better not back out, Izuku! You already made all of us into women! To say nothing of how many times you came in us…”

To say Izuku is reeling by this point would be an understatement. Mina’s final words, however, make him go wide-eyed at the realization that… that last night’s efforts might have made him a father not once, but thrice over. More than that, he was now engaged to three of the most beautiful women he’d ever met?! And all three of them wanted to be with him so badly they were willing to share him?!

At a certain point, distracting himself from Mei’s efforts to titfuck him to an orgasm becomes detrimental to holding back his release, rather than helpful. He’s so focused on everything Momo and Mina are saying that it creeps up on him, and before he can try and hold back a little longer, Mei lets out a triumphant, gleeful little giggle as he proceeds to cum all over her face and tits. He cums and cums, while Momo and Mina look on in hunger.

“I-Izuku… you cum so much it’s ridiculous…”

“Mm, Ms. Responsible is right, you have the BIGGEST loads ever!”

Izuku never really thought about it, but he supposed there WAS a lot when he masturbated. Still, was that really a good thing?

As Mei moans, scooping his cum up off of her creamy tits and into her mouth, Mina scoots forward and yanks the inventor back away from him, pushing her aside.

“My turn!”

Without missing a beat, Mina climbs aboard and impales herself on his cock. Izuku’s eyes bulge out of his skull as her already fucked cunt nevertheless tightens around his dick, the gorgeous alien-like girl moaning as she bounces up and down on his member. After a moment, she gives him a wicked sort of grin.

“Better take charge soon, Izuku, or the three of us will walk all over you. Well, Mei and I will. Little Miss Heiress here is a submissive little bitch at heart. But me? I like to be… challenging.”

Leaning forward, she plants her hands on his chest and moves up into a crouch, before riding his cock even faster than Izuku thought possible. As Momo looks away, blushing hard but not denying Mina’s words, Izuku… Izuku feels something primal awakening in him. It’s a small voice but growing in volume. He thinks it might be a leftover from the night before, but it’s an instinct he could ignore now, if he wanted to. Just… an option.

Give it to her. Fuck her hard. Claim your mate.

It was an option Mina was outright goading him into taking though. With a lustful growl, Izuku rises up. His hands grab Mina by her hips, and he slams her back down onto his cock all the way, so that her feet collapse under her and she’s back to kneeling as she straddles his crotch. Her eyes widen and her mouth drops open, as she immediately cums on his cock.

Hmph, who was the submissive one here again? It was supposed to be Momo right? As Izuku fucks Mina hard and fast from below, the pink-skinned beauty doesn’t put up much more of a fight. Her tits bounce all over the place and she’s rag dolling pretty hard, right up until he cums inside of her. Izuku doesn’t even think about it until after the fact… he just does it, and only as he’s finishing filling Mina with his seed does he realize what he’s done.

Not that she minds.

“Heh… that’s more like it.”

Collapsing backwards, Mina passes out again, clearly still feeling yesterday’s events and not having much energy at all left in the tank. But Izuku doesn’t have time to worry about her, because his eyes have already alit upon Momo… Momo, who has turned away from him, bent over and planted her face in the bed as she reaches back and spreads her thighs apart to show off her messy slit and offer it up to him.

Hm, maybe Mina was onto something with what she said earlier. Meanwhile, that little voice in the back of his head is telling him to ‘claim’ Momo as well, and since his cock is still hard and its obvious, she wants it… fuck it.

Izuku rises from the bed finally, in order to get into place behind Momo Yaoyorozu. He’s in the raven-haired young woman a moment later, filling her with his cock as she moans throatily. Seeing how he has her to thank for the fact that he’s only engaged to all three of them rather than straight up married, Izuku takes things nice and slow… until Momo croaks out a request.

“H-Harder… please…”

From that point on, he doesn’t hold back, and Momo doesn’t once ask for mercy or for him to slow down. He fucks her into the bed, pounding into her like a jackhammer, and she squeals and shakes and creams herself again and again on his cock. This time around, he at least manages to remember to warn her that he’s getting close… but her answer isn’t all that surprising, when he tells her he’s about to cum.

“I-Inside! Fill me up again! Please Izuku, I NEED it!”

Who knew that Momo of all people had this slutty wild side to her? Still, the thought of filling her with his cream again does appeal to Izuku too much for him to avoid it. He groans as he cums inside of her, filling her to the brim with his seed.

Only as he’s pulling out does he realize that she’s passed out, just like Mina. They really were all still tired from last night, and yet they’d gone ahead and instigated another round of sex with him anyways. Izuku didn’t know what to make of it… except that when he looks around, he can’t find Mei anywhere.

Blinking, Izuku’s gaze sweeps across the hotel suite… until suddenly, he realizes he can hear water running from the nearby bathroom. A naked Mei pokes her head out and gives him a grin as she licks her lips.

“Coming?”

Izuku doesn’t need to be told twice. Within moments, he’s in the shower with Mei, pushing her up against the glass door and thrusting into her from behind as she moans wantonly. She’d already cleaned up a bit while he was fucking Momo, but now they’re getting her messy again, even as the hot water cascades down their bodies, making them all the more slippery.

As Izuku fucks Mei from behind, he frowns.

“Mei… how much of last night was a real experiment?”

Looking back over her shoulder at him, Mei actually has the audacity to look hurt.

“All of it, of course.”

Izuku feels guilty for half a second, before Mei elaborates.

“I wanted to see if you cared about me as a friend or something more! That was the whole experiment! Mina and Momo were unplanned… but knowing what I know now about your stamina, I can tell that I’ll need them, heh! Even now you’re, mm, so fucking rough…”

Izuku growls, having sped up as she explained. He stops just shy of potentially breaking the shower door that he’s pounding Mei up into, even as he processes what she’s just told him… and ultimately accepts what happened. Mina and Momo and Mei… all three women were apparently in love with him. Or cared for him enough to want to be married to him. Now, the four of them were apparently engaged and life… life was definitely going to get more complicated from here on out.

But Izuku found that he wasn’t too worried about it. Call it those primal instincts that had taken up residence in the back of his head, but somehow, he knew everything would be just fine, so long as he had his girls…

That didn’t mean Mei was off the hook any time soon, and after a moment of thought, Izuku takes his soapy thumb and begins working it into her backdoor, with every intention of loosening her anus so that he can properly ‘punish’ her with his cock in just a little bit. Mei doesn’t raise a fuss, even as he delivers the punishment… so maybe they’ll be able to make this work after all.
