The Successor (My Hero Academia)

She was in over her head. No doubt about that. As she lounges on the bed, staring with wide eyes at Mirko and one of her students, Yu Takeyama reflects on exactly how she got her, and is forced to acknowledge that its her own damn fault.
 
Mirko was just… so persuasive. REALLY persuasive. Her ‘Senpai’ had gotten under her skin, giving her attention that Yu couldn’t help but crave. One thing had led to another, and before she even knew what was happening, she was drawn back home, where she and Mirko had had tons of f-fun together. Then, all of the sudden, the Rabbit Hero said she’d called a guy over. Ya know, to do the things they couldn’t do.
 
… Made sense to Yu, she supposed. Only, she hadn’t even stopped to question who the guy might be. If he was good enough for her ‘Senpai’ then he was probably good enough for her, right? In hindsight, she should have asked more questions. Though, whenever she tried to, Mirko had this annoying tendency of shoving her head down between those powerfully built chocolate thighs of hers to shut Yu up. Somehow, she doesn’t think it would have gone any different for her if she HAD asked, rather than just leaving it be.
 
Regardless, now Yu… now Yu had a choice to make. As Mirko kneels there next to the Midoriya kid, his throbbing cock a stark contrast to her dark skin, Yu feels frozen under the Rabbit Hero’s expectant gaze. But… not for long. In the end, Mirko is right. She didn’t care when she didn’t know who it was. And at this point, she was in too deep to back out, wasn’t she?
 
More than that… Yu was curious. Call her shallow. Call her vain. But she’d always thought of herself as… hmph, better than most other people. That said, she was also very aware that there were people above even her. And in her eyes, Mirko, her ‘Senpai’, was one of them. So, if MIRKO said that Izuku Midoriya was worth ten of any man that Yu had ever been with… she could admit it. She was intrigued.
 
Slowly, Yu climbs off of the bed and falls to her knees, crawling over. As she does so, Mirko’s lips curl into a satisfied smile, and she knows she’s made her ‘Senpai’ happy in this moment. The blonde heroine makes sure to put some sway in her hips, and to arch her back enough that her ass is lifted high in the air. She notices the way Midoriya’s eyes are drawn to it, an assessing and almost analytical gaze to him.
 
That’s the other thing that decides it for her. In just a couple of minutes of interacting, Midoriya has shown that he’s mature for his age. Those eyes of his… there’s not a hint of innocence to them. Whether that was because Mirko got to him… or HE got to Mirko, Yu didn’t know. She was growing more and more excited to find out, however.
 
Finally reaching him and her ‘Senpai’, Yu gasps as Mirko immediately reaches up and grabs the back of her head by her hair, gripping down tightly as she drags Yu all the closer.
 
“That’s it. That’s my darling kouhai.”
 
Blushing but finding it easy to fall into the role even in front of Midoriya, Yu moans throatily.
 
“Mm, yes Senpai~”
 
Paying her barely any mind, Mirko looks up at Midoriya and grins.
 
“Do you like her, Izuku? I got her just for you.”
 
Just… just for him? So, all of this was to feed Yu to her student on a silver platter? The heroine’s heart thuds in her chest at that, even as Izuku looks down at her for a moment longer before smiling a thin smile.
 
“She’s pretty enough, Rumi. But I can’t really pass judgment if I haven’t sampled all she has to offer, can I?”
 
He’s on first name with Mirko?! Yu’s eyes flicker between the young man and the Pro Hero beside her, even as Mirko licks her lips and nods, not upset in the slightest by his words.
 
“O-Of course. Well, kouhai? You heard him! Get to it!”
 
Yu gasps, as she’s shoved forward into Izuku’s crotch. Her face presses up against his throbbing, pulsating cock and she finds herself breathing in his scent. A moment later, Mirko lets out a disgruntled noise and yanks her back again, this time using her other hand to grip the young man by his dick and guide it right to Yu’s lips before forcing her down his length.
 
“Gluuuuuuughk!”
 
It’s humiliating. Degrading. Dehumanizing. Her ‘Senpai’ quickly begins to ride Yu’s face upon Midoriya’s cock, forcing her up and down his dick and choking her on the sizable specimen. Yu gets it. Midoriya is… gifted in the size department. She can see how Mirko might say that he was worth ten of any other man. She still thinks that might be an overstatement, but she does get it.
 
That said… this isn’t what Yu expected to be doing tonight. Deep-throating a student’s dick while Mirko guided her up and down his shaft. Never in a million years would Yu have thought she would be here, in this moment.
 
… So then why is it such a turn on? She knows that she’s a little vain. She knows that she’s always been the kind of woman who has to be the center of attention. She’s always thought she preferred being waited upon and worshipped, rather than… debased in this case. And yet, the more Mirko forces her to suck his cock, the more turned on Yu gets. Her thighs rub together for a moment before she just jams a hand down there betwixt them and begins going to town on her cunt.
 
Her gagging becomes interspersed with multiple moans, as she gurgles her way up and down Midoriya’s dick. The thing is… despite her Quirk, Yu has never really believed size was everything, at least when it came to sex. But here and now, she’s starting to wonder if Mirko has unlocked something in her. Some sort of hidden Size Queen fetish not even she knew was lurking in the back of her mind.
 
Or maybe it’s Mirko herself, and the added component of having her ‘Senpai’ using her to get her man off. She’s nothing more than a tool right now, a toy if you will. She’s an object that Mirko is riding up and down Izuku’s dick, little more than a living onahole. And that… that is an immense turn on for her, to Yu’s equally immense surprise.
 
With two fingers buried in her twat, the heroine gurgles as she stares up at Midoriya from her kneeling position in front of him. His cock is buried in her throat, in no small part thanks to Mirko’s hand fisting her hair and pushing her head down his cock. Gurgling, nostrils flaring, the lack of breathable air is doing funny things to Yu. Her eyes are fluttering, barely staying open… and yet… and yet…
 
With a choked, muffled squeal, she cums, experiencing one of the most explosive orgasms she’s ever had before. Her body shakes and buckles in its kneeling position, while the noises trying to emit from her throat reverberate up through Izuku Midoriya’s incredibly meaty cock. She groans around his dick, before a moment later, without warning, he begins to cum as well.
 
While she’s still trying to recover from her own orgasm, Izuku cums and cums, and Yu… well, she chokes HARD. Mirko doesn’t seem inclined to let her up at first, and so no small amount of seed ends up exploding out of her nostrils and the sides of her mouth, blowing back onto Izuku’s crotch and dribbling down onto his balls.
 
Her vision starts to fade, as she feels like she might just drown from the sticky seed clogging her throat, combined with the throbbing slab of man-meat stretching her jaw. But just before consciousness leaves her, Mirko abruptly yanks her back, and Yu coughs and hacks as she finally gets some fresh air into her lungs.
 
For the next few moments, all that the blonde heroine can do is breathe. Breathe… and process what just happened. It should have been traumatizing. It should have been a no brainer to get the fuck out of dodge. Instead… instead, she thought it might just be the hottest thing she’d ever done. And even as she’s thinking that, the blood rushing in her ears finally begins to die down, and she hears Mirko’s voice, whispering to her.
 
“-ood girl. Such a good kouhai. You did wonderful.”
 
The positive reinforcement, combined with the immense arousal and her gushing cunt, leaves Yu feeling a certain sort of way. She can’t explain it. All she knows is… she wants more. And so, like the ‘good kouhai’ she is, she asks for it.
 
“M-More… moooore~”
 
There’s a pause, and then a giggle from Mirko.
 
“Well, Izuku. You heard her~”
 
In response, Midoriya just snorts, and that big fat cock of his, still rock hard, slaps down onto Yu’s face for a moment before drawing back.
 
“That I did. That I did.”
 
-x-X-x-
 
 
He’d been ready to make a call, if necessary. One of his Quirks allowed for short-term memory loss. Anywhere from an hour, all the way up to a day. Of course, he also had a couple Quirks that could take even more than that, but he was loathe to use them. Izuku was… capable of a lot of things but robbing someone of their memories felt a step too far. He was supposed to be a hero, after all.
 
Still, in this case, he would have done it, if it became absolutely obvious that Mt. Lady was… intractable. If she’d shown any further reluctance, or if she’d been completely unwilling to do anything with them… Izuku wouldn’t have forced her. Nor would he have let Rumi force her either. Instead, he would have simply removed the Mineyama Hero’s memory of him in Rumi’s house.
 
And yes, that would have in turn caused problems with Rumi, more than likely. He would have been forced to provide some sort of explanation… while at the same time coming down on the Rabbit Hero hard for endangering them so. He could have gotten away with it though he was pretty sure, if only because he had Rumi under control.
 
… Or so he’d thought. Admittedly, this new habit of hers, corrupting her colleagues and presenting them to him like a cat with a dead bird in its jaws, was troubling. But not as troubling as it could be. After all, she’d chosen well, hadn’t she?
 
“MMPH!!!”
 
WHAP! WHAP! WHAP!
 
They’ve moved things back to the bed now, with Rumi and Mt. Lady returned to their original position. Rumi on her back, and the blonde heroine between her chocolate thighs, dutifully eating her out. The only difference was, now he was in the mix. Specifically, Izuku was kneeling behind Mt. Lady, plowing into the heroine from behind, his hands digging into her plush backside even as his thighs clap against her thighs.
 
She’s not nearly as in shape as Rumi. Or rather, her shape can be described as voluptuous and pillowy in all the right ways. Thanks to her Gigantification Quirk, she doesn’t need to work out overly much, or keep herself at tip top physical form. Not when she can literally stand taller than most buildings at any given moment.
 
There’s something enjoyable to be said about her soft body, and Izuku groans as her slippery wet insides clench and squeeze around his cock. She, in turn, moans into Rumi’s pussy, until suddenly the Rabbit Hero arches her back and gasps, very clearly experiencing an orgasm that causes her to spray her pussy juices all over Mt. Lady’s face.
 
If Rumi’s ‘kouhai’ minds this, she doesn’t say anything. Not even when the chocolate-skinny bunny with a breeding fetish suddenly pulls away from her, swinging her legs over Mt. Lady’s head and climbing up off the bed. Izuku doesn’t stop fucking the blonde in front of him, and Mt. Lady clearly doesn’t want him to stop if her vocal moans and mewls and cries are anything to go off of.
 
Still, he DOES give Rumi a raised eyebrow as she stops to kiss him for a moment before walking by entirely. Turning his head, Izuku watches as the Rabbit Hero goes over to her closet and throws it open. Hanging from several hooks are a few different cosplays, some of which he’s seen her pull off and some he hasn’t just yet.
 
But in the moment at least, Rumi ignores those in favor of leaning over. Her little puffball of a rabbit tail twitches, and her chocolate ass is on full display as she reaches all the way into the back of the closet and pulls out a big trunk.
 
Lifting it up with ease, a testament to her physical strength if the way her arm muscles have to bulge is any indication, Rumi walks back over to the bed and drops the trunk down onto the bed beside him and Mt. Lady. Still fucking the plush, voluptuous heroine doggystyle, Izuku leans forward as Rumi grins wickedly and unlatches the trunk, opening it facing him so he can see the contents inside.
 
There’s a bunch of stuff… all of it bondage themed. Rope, gags, handcuffs… all the stuff you would expect. As well as some additional erotic tools, and some whips and chains for good measure. It’s a lot, and as Izuku’s eyes pan over it all, Mt. Lady is too busy moaning and cumming upon his cock to notice anything. Rumi, meanwhile, licks her lips and climbs onto the bed, hugging him from behind and nibbling at his ear before whispering to him.
 
“Do you like them, Izuku? I got them for you… to use how you see fit.”
 
Well now, that was an open invitation if he’d ever heard one. Looking at the open trunk, and then down at Mt. Lady’s arched back and fat backside, he envisions her all tied up for a moment, a ball gag in her mouth, arms behind her back… and a riding crop coming down on her pillowy posterior again and again. At the same time though, he imagines Rumi joining her, just as trussed up.
 
One thing was for sure, Mt. Lady’s overall enthusiasm and sluttiness had quelled any worries Izuku had. She wasn’t going to be a problem; he could tell that much right off the bat.
 
And another thing he knew for certain… the night was still young, and he, Rumi, and their ‘kouhai’ were just getting started.
