The Successor (My Hero Academia)

“Glughk! Glughk! Glughk!”
 
… He’d expected one of two outcomes when he decided to leave things in Momo’s hands. One, she would confront him as soon as humanly possible and he would have a chance to explain. Now, whether that would actually pan out or not would be up to her. Izuku had no intentions of restricting himself to one woman. He’d made no promises to Momo, no declarations of romantic fidelity. They hadn’t called each other boyfriend and girlfriend or anything like that.
 
In terms of getting married one day, Momo WAS on the shortlist for candidates. But only if she proved amicable to the idea of sharing him with plenty of other women. In a way, her catching him with Ochaco was a godsend. He would find out one way or another how she felt about it… or so he’d figured.
 
The other outcome he’d considered a likelihood was that Momo would back off completely. That she wouldn’t confront him but would instead begin avoiding him. That didn’t seem in character for the brash heiress, but Izuku wouldn’t have put it past her. After all, Momo was still new to sexual relationships like theirs, and she was just a young woman regardless of her maturity in other arenas.
 
… But neither of those things had happened. Glancing down at his crotch, Izuku makes eye contact with Momo Yaoyorozu as the Student Representative of Class 1-A greedily and enthusiastically sucks his cock for all she’s worth. Standing there in one of U.A.’s unused classrooms, dragged here by Momo the moment he stepped foot on campus this morning, Izuku isn’t sure what to think. He’s certainly enjoying her technique… but what exactly is this?
 
Is she trying to strike a middle ground of sorts? He knows she was peeping on him and Ochaco. But she doesn’t know he knows. He had intended to let her say something, but instead of confronting him over it, she seemed to be more eager than ever to engage in sexual relations with him. And yet, somehow Izuku didn’t get the impression that Momo was trying to… lock him down or anything like that.
 
At first glance, that might have been the assumption. That she was attempting to show him he didn’t need any other woman save for herself via action rather than words. It wasn’t the case, but it might have been an understandable reaction to what she’d witnessed if she truly felt like she was in love with him. Yet, that wasn’t the vibe Izuku was getting.
 
It wasn’t as… desperate as it would have needed to be for that to be the case. Momo was certainly enthusiastic, but she wasn’t afraid of losing him. She was, if anything, more excited than the last time they’d been together. And that was after witnessing him with another woman. Was it possible Momo was… that kind of woman?
 
“Gagkh! Gagkh! Gagkh!”
 
Figuring that out would have to wait for later, because the final bell would be ringing soon and Momo was well aware of that. Her efforts redouble as she does her best to get him off before that bell rings and Izuku isn’t nearly cruel enough to deny her such a victory. With a grunt, he finally cums and Momo hastily swallows every last drop, guzzling down his jizz like her life depends on it. It’s a far cry from the innocent virginal heiress he’d deflowered just a little while ago. Honestly… he’s a bad influence on her, isn’t he? But then, just him alone shouldn’t have made Momo like this so fast…
 
Pulling back off of his cock with a pop, Momo wastes no time in tucking him back away into his boxers and fixing up his pants and belt. Then, she gives him a smile as her tongue slips out to catch a trickle of his cum.
 
Izuku just raises an eyebrow and shakes his head, continuing to play dumb.
 
“What was that all about, Momo?”
 
The Class Rep just hops up to her feet and shakes her head right back. This was her chance to confront him if she so chose, but instead she gives him a mysterious sort of smile.
 
“Oh… no reason. Let’s get to class now, shall we?”
 
He’s half-tempted to do the confronting now, but whatever game Momo is playing… he refuses to lose. And so Izuku just nods and lets her lead him out of the abandoned classroom as they make their way to Class 1-A with just a couple minutes to spare. He almost expects their arrival at class to be Momo’s big plan, having them enter together and making it apparent that they’re a couple.
 
But no, that doesn’t happen either. As they enter the hallway leading to class, Momo seems to jolt, as if just realizing how it will look. Before Izuku can even say anything, she picks up the pace and enters the classroom well ahead of him, leaving him to enter alone. Honestly, he doesn’t quite know what’s up with the beautiful young heiress… and that sort of makes it all the more exciting.
 
At least it doesn’t seem like he’s hurt her in any way, so he doesn’t have to start looking over his shoulder for Yor Yaoyorozu just yet. Though that did remind him that he needed to get back together with Tomura sometime soon to find out what his ‘big brother’ had found out about Momo’s older sister.
 
For now… well, it was time for class, wasn’t it? So he should focus on that.
 
-x-X-x-
 
As Momo takes her seat, she’s damn near vibrating with excitement. Her belly feels warm, filled with Izuku’s cum.
 
She’d gone home last night and stayed up very late doing… research. It turned out the internet had a name for the things Momo was feeling. Momo had a fetish. One she hadn’t fully understood, but luckily the internet was more than willing to spell it out for her. It would seem, though she still had to confirm it, that Momo… was into Netorase. Or maybe not.
 
She definitely liked spying on others while they had sex. That was called Voyeurism. However, upon further exploring her feelings, Momo couldn’t help but feel like a larger part of the pleasure she’d gotten from watching Izuku and Ochaco engage in sexual relations was from WHO it was, rather than just what SHE was doing. Izuku specifically fucking other girls… just did it for her, Momo believed.
 
She’d done extensive testing on this, with her sheets being VERY messy by this morning. Just envisioning watching faceless people going at it while they didn’t know she was there WAS arousing… but not as arousing as imagining Izuku fucking another girl while he didn’t know she was there. Although, Momo wasn’t sure the unaware component was necessary either. Just envisioning Izuku fucking another girl while she watched was enough to make her absurdly wet.
 
However, in her internet research she’d found another form of this. Sometimes the woman HELPED the man fuck another girl. It was a two-pronged assault sort of thing, and Momo found that she enjoyed THAT just as much as the concept of Netorase. Dominating another girl with Izuku… that would be pretty hot, wouldn’t it? So maybe she wasn’t into Netorase. Maybe she was into that instead. Or maybe she was even into both!
 
Hence… the verdict being a little unclear. Nevertheless, she liked it when her man, or rather the guy she liked, had sex with other girls. Momo’s research had unveiled that this made her rather unnatural. It was a niche fetish that most people looked down upon. It was commonly tied in with humiliation and masochism, but Momo wasn’t sure she even enjoyed those sorts of things. Or if she did, did she enjoy being humiliated, or did she like the idea of humiliating and degrading the girls Izuku was fucking instead of her?
 
She wouldn’t know unless she told Izuku that she’d caught him and Ochaco going at it. She wouldn’t know unless she asked him to let her watch him fuck other girls. But Momo was afraid. She wasn’t sure she could go through with it. So instead… she’d said nothing. At the same time, she couldn’t just let things be! She wanted… she didn’t know exactly what she wanted from HER relationship with Izuku. But she did want to make sure he knew how much she cared about him.
 
Hence the Good Morning Blowjob. Ill-advised? Perhaps, especially since it saw them both nearly arriving to class late. But in the end, Momo couldn’t bring herself to regret it. She couldn’t bring herself to regret any of it. Really, she-
 
“Mr. Midoriya. I can tell that something is distracting you. You can tell me all about it later in detention!”
 
Momo jolts out of her introspection, eyes widening as her head whips up and then around. Their teacher, Mirko, didn’t tend to hand out many detentions. But then to be fair, she was sort of a certified badass, so even people like that bitch Bakugou tended to listen when Mirko spoke. In this instant however, Momo had gotten caught up in her own thoughts. She was setting a bad example for the rest of Class 1-A.
 
However, instead of Momo getting called out… it was Izuku. There’s some shuffling as the entire class looks between Mirko and Izuku. The young man looks undeniably surprised for a moment before something flashes across his face and he gives a simple nod.
 
“Yes ma’am.”
 
The anticipation that had been building in the class immediately fizzles out at that. It felt like everyone was expecting some sort of confrontation. They were expecting Izuku to argue with their teacher on the validity of his detention. Him just accepting it was effectively an admission of guilt, and thus rather boring to the rest of the class. Everyone faces forward again at that… save for Momo herself.
 
After all, wasn’t this her fault? Izuku was probably distracted thinking about the blowjob she’d decided to impulsively give him! He might not be willing to defend himself, but Momo should at least step in and… and say something, maybe! The only problem was, Momo didn’t know what the fuck she was supposed to say in this situation. Before she can formulate the words, she catches it. Just a glimpse.
 
She’s pretty sure no one else sees it, because everyone else has turned back around, but there’s a moment where Izuku and Mirko’s eyes linger on each other. A moment where Izuku’s face goes from vaguely chastised to an amused smirk, and Mirko’s gaze stops being so accusatory and becomes a little… embarrassed.
 
It’s only a moment. And under normal circumstances, Momo probably would have just written it all off as a trick of the light. It almost certainly didn’t mean anything… right? Except Momo had spent all night long on the internet doing ‘research’. She was seeing things she’d never seen before. And maybe she was making a mountain out of a mole hill, but it certainly seemed like Izuku Midoriya and Mirko the Rabbit Hero… might have a thing.
 
… She was probably wrong. Probably dead wrong, even. But Momo’s breath catches in her throat all the same, and in the end she doesn’t try to speak up in Izuku’s defense. He doesn’t seem at all upset about getting detention. So maybe… well, maybe it wasn’t detention at all. Momo would be sure to find out… because she was going to stick around and spy on Izuku and their teacher after class later today…
 
The very thought of Izuku and Mirko together has Momo rubbing her thighs surreptitiously under her desk. The Class Rep tries to keep her blush to a minimum, but it’s hard. Oh heavens… she’s becoming such a l-lewd young lady…
 
-x-X-x-
 
Momo was spying on him again.
 
S-SMACK!
 
“Sheesh, you really called me out like that, didn’t you Rumi?”
 
“Mm, s-sorry sir~”
 
Izuku just shakes his head as he bends the Rabbit Hero over her desk, fucking his teacher hard and fast from behind. All the while, Momo is watching them fuck from an air vent of all things. How she’d managed to fit into there, and why she hadn’t chosen to spy from the window or something, Izuku couldn’t say. But, well, he wasn’t going to be the one to mention her presence. He’d already decided he wouldn’t.
 
At the same time… reaching forward, Izuku slides one hand around under Mirko’s jaw and pulls her head back, forcing her spine to arch as he continues to pound her all the harder. Leaning in close, he nibbles at her massive rabbit ears, prompting her to squeal and cum for him. It’s in the aftermath of this orgasm however, that she murmurs under her breath to him.
 
“… you know our straight-laced Class Rep is spying on us from the vent, r-right?”
 
Izuku just chuckles and nods, his chin coming up to press into Mirko’s scalp as he does so, giving her his affirmative answer. Letting out a shuddering moan, the Rabbit Hero doesn’t say anything more about it. She probably assumes he’s playing some sort of game, and of course given their relationship dynamic, she’s not going to question him on that.
 
The funny thing is, Izuku isn’t the one playing games here. Momo is. He doesn’t quite know WHAT the Yaoyorozu Heiress is up to just yet, but he’s curious to find out how things escalate with her. He’s more than happy to leave it all in her hands, and let Momo make her own choices.
 
Admittedly, he had been distracted earlier in class when Mirko had decided on a whim to give him a detention. He’d not quite been daydreaming, but he had been thinking about Momo Yaoyorozu and what to do with her. Mirko had taken advantage of that fact to get him alone with her after class for a ‘detention’. A detention that had rapidly devolved into him fucking her over her desk.
 
With a sigh, Izuku finally speaks, even as he continues to fuck Mirko from behind.
 
“You can’t do that going forward. Giving me detention so I fuck you… my classmates will start to suspect something is up.”
 
He could just imagine it. Momo spying from the air vent. Ochaco spying from the door. Even Katsumi and Shouko Todoroki might start to suspect it was a cover for some extra training or something, resulting in both young women peeking through the windows of the classroom from different spots hidden in the brush just outside.
 
It wasn’t that bad yet, but they already had one of his classmates peeping on him, and if Izuku didn’t already know Momo was getting off on watching this from the arousal he smelt coming off of her, he would be worried she was trying to build a case against him or even Mirko. She WAS the Class Rep after all. She was supposed to be the responsible one. They were lucky she had turned out to be a nasty little pervert, but that didn’t mean they’d get lucky forever.
 
Fucking Rumi hard and fast from behind, Izuku waits a beat for her response. When he doesn’t immediately get it, the gorgeous dark-skinned bunny too busy moaning up a storm, he lets out a growl and winds back his hand, spanking her ass yet again.
 
S-SMACK!
 
“Eep! Y-Yes… sir… nngh, s-sorry sir… t-though… I hope you don’t mind t-that I invited… c-company.”
 
Izuku blinks at that. Just as Rumi is speaking, he feels a presence rapidly approaching the door to the classroom from just down the hall. He immediately pulls out of Rumi and with the use of his Quirks he’s able to fix up both her AND his clothing before their ‘guest’ can enter. Only then does Izuku focus enough to figure out who he’s dealing with. His lips thin out as he registers who it is just before the door opens and they step inside.
