A/N: In which Izuku does what must be done to NTR an NTRing Bastard.

-x-X-x-

… If he’s doing this, he’s going to do it right. As Ryuko leans forward, reaching for his crotch, Izuku’s hand snaps out and he grabs the heroine by her short hair, yanking her head back and causing her to gasp as she looks up at him from beneath her ever-present fringe.

“No hands. Keep them clasped behind your back.”

Ryuko obeys unquestioningly, even as Rumi watches on with a wide grin. The Quirk Izuku is using to make his voice slightly irresistible ensures the Dragoon Hero’s compliance, even as she looks from his eyes down to his crotch, clearly wondering what he’s going to do next. Izuku just smirks.

“Well? Did I say to stop?”

Understanding dawns on the heroine, and her breath hitches as he guides her forward by the hand he has in her hair.

“Take it out. Use only your teeth. Understood?”

A shiver runs down Ryuko’s spine, even as she nods.

“Y-Yes.”

And with that, she gets started on extracting his cock from its confines with nothing but her mouth. It’s no easy task, but then that’s kind of the point. Izuku isn’t doing this just to establish dominance, he’s also doing it to buy himself the time he needs to figure out what he’s up against. If he’s going to go to war with another man he’s never even met before, then he needs to understand the battlefield. That being Ryuko’s body.

Off to the side, Rumi is watching this with an expression of pure glee on her face. There’s a hint of jealousy as well, but she’s the one who set this up, and she’s clearly enjoying the fruits of her labor so far. Her hands twitch, and Izuku can tell the chocolate bunny wants nothing more than to touch herself to the sight of her friend being forced to extract his cock with nothing but her teeth. She doesn’t just yet, but soon enough she’ll give in, he can tell.

Meanwhile, up in the airduct… Momo has already given in. Not only can Izuku hear her fingering herself with the help of his Quirks, but he can smell her arousal, thick in the air. The spying young woman is having the time of her life watching them right now, clearly getting off on him toying with Ryuko like he is. Izuku still didn’t fully know what was up with Momo, but he supposed it was fine so long as she was, heh, having fun.

Focusing back on the matter at hand, Izuku turns his gaze down to Ryuko once more. He doesn’t just look at her though, he outright analyses her. His father had always been a fan of having a Quirk for every situation. This included being able to do the work of an entire blood lab and hospital all by himself. All for One had gone out of his way to acquire a number of intrusive Quirks that would allow one to look deep within a ‘patient’ and know everything there was to know about their biological makeup.

Obviously, Izuku didn’t usually use these Quirks without good reason. Not only was it a bit too overwhelming for him to have them on all the time for every interaction he had with anyone, but it was also a slight turn off. All of that squicky information, all of those disgusting details… it didn’t really set the mood, to say the least.

But it needed to be done. He needed to understand what this douchebag had done to Ryuko. Rumi clearly hated the guy’s guts, and Ryuko certainly didn’t seem proud about how she’d cheated on her last boyfriend with him. Which left Izuku to figure out why the fuck the Dragoon Hero stuck with this new guy in the first place.

There are Quirks for everything. And Izuku has a lot of them, but not all of them. This guy… without seeing his Quirk in action, or just outright taking it for himself and gaining comprehensive understanding that way, Izuku could only begin to guess. Still, he can see what’s wrong with Ryuko. Her body… its suffused in this guy’s musk. However, it’s far more than just a scent or smell. Somehow, the man has managed to seep his very essence into her pores. Every inch of her body is covered in him.

Izuku can immediately tell that it won’t matter how good of a lay he is. It doesn’t matter if he fucks Ryuko’s brains out. He could completely rock her world and unless he outright mind broke her in such a permanent fashion as to cause personality death, she’d just end up back with the douchebag. Obviously, that wasn’t something he was willing to do, even if he theoretically COULD do it.

It’s not about sex with her and her ‘boyfriend’ at this point. In fact, for all he knows, sex with the man might be incredibly mediocre. No, what Ryuko was suffering from was plain old addiction. The guy had addicted Ryuko to not just his touch, but his very presence. She would always find herself going back to him, which would in turn cause more of his essence to seep into her body. An endless cycle where unless he abandoned her entirely, she would never willingly choose to stay away from him for the length of time needed for her to be free.

Insidious to say the least, and Izuku didn’t doubt that it was fast acting as well. The guy, whoever the fuck he was, clearly had a massive ego thanks to his Quirk. He was even convinced that one roll in the hay would get him Mirko the Rabbit Hero as well. Izuku certainly had no reason to doubt the man’s confidence either. For all he knew, Rumi might have fallen for the guy if she’d ended up spending enough time in his presence.

After all, while sex probably helped, it almost certainly wasn’t just that. Just being around the guy and breathing in his musk and absorbing his essence slowly endeared you to him, Izuku imagined. He could even picture how it would have gone in his mind’s eye if Rumi hadn’t already been working at UA and fallen into her twisted relationship with Izuku.

She might have gone to the guy to give her a piece of his mind and even threaten him, but of course he wouldn’t have backed down. Then, maybe he shows up at one of her events or something, to continue pushing his Quirk on her. Until eventually… she’d fall. Just like Ryuko had before becoming a teacher here.

Of course, with Rumi a teacher here, the guy had ultimately missed his chance. Or… had he? Glancing up, Izuku gives the fidgeting, twitching Rabbit Hero a quick look with his Quirks too. What he sees disturbs him to his core. There are bits and pieces of the guy’s essence on Rumi as well, despite her never having deigned to meet with him in the first place. The only explanation… is that Ryuko isn’t just a victim, she’s a carrier.

In the end, the guy’s confidence suddenly makes way more sense. He sent Rumi that video message because he knew the more Rumi hung out with Ryuko, the more of HIM would rub off on the chocolate bunny. Until eventually… she wouldn’t be able to resist.

Insidious and dangerous. Izuku couldn’t let something like that continue.

Meanwhile, down below, Ryuko has finally managed to get Izuku’s cock out of his pants and into her mouth. As she dutifully sucks on his dick, she’s looking up into his eyes. Her hands are still clasped behind her back, but there’s a challenge in her gaze, as if to say so far she’s not impressed with him. But then, he was up against literal chemical addiction here, so… he was going to have to take drastic measure, it seemed.

Reaching down, Izuku grabs hold of Ryuko’s head with both hands. His fingers slide through her short hair and across her scalp. As he gets to work, Ryuko gurgles in surprise around his cock, her eyes immediately rolling back in her head as he sends a very minor pulse of electricity right into her, specifically aiming for the brain’s pleasure centers.

“Glurrrhgugl!”

In that instant, her mouth might as well have been her cunt, as she noisily cums from sucking his cock. Her body shakes and spasms, but to her credit she keeps her hands clasped behind her back all the while. Izuku is just getting started of course… and in fact, even this action has ulterior motives. He’s not just driving her wild with his touch upon her scalp. He’s using another Quirk to push the douchebag’s essence out of her at the same time.

As she gurgles there on her knees before him, her tongue swirling around his cock and her lashes fluttering rather wildly, Izuku watches as she quickly begins to sweat profusely. The ‘sweat’ is slightly opaque but mostly clear fluid, and its streaming from all of her pores. Izuku narrows his eyes at that, before driving her all the way down his cock in one go.

“Gluuuuuuuuuughk!!!”

Ryuko shudders upon his dick as he plows down the back of her throat and into her currently hyper-sensitive gullet. She cums at least three times while involuntarily struggling against his hold on her. When he pulls back, her eyes are lidded and she’s panting for breath, her chest heaving in its top. But that’s just it… she’s overly dressed for this.

Continuing to slide her up and down his dick, Izuku calls out to her again, his Quirk-enhanced voice forcing her to hear him even in her current state.

“Strip, now.”

It doesn’t force her to obey, but Ryuko still jumps to do his bidding. Her hands unclasp from behind her back and she hastens to strip naked. She drags her clothing off of her body piece by piece, all but tossing the garments aside until finally, she’s completely naked.

While she’s doing this, Izuku checks on both Rumi and Momo again. He’s glad he’s done so, because in looking over at a now-masturbating Rumi, he realizes that bits of the man’s Quirk that he’s pushing out of Ryuko are in fact airborne. Not all if it is confined to her sweat. He’s able to stop any of the airborne essence from reaching Rumi and Momo however with a quick use of an unseen wind Quirk that collects all of the particles and sends them splattering harmlessly into the wall of the classroom instead. Their shelf life in open air is minutes, so the danger won’t last long.

Yes, Rumi and Momo are both masturbating enthusiastically at this point. Momo has never stopped, while Rumi has given in to her instincts and desires. The Rabbit Hero freezes up for a moment when Izuku’s eyes fall upon her once more, and she gives him a sheepish smile. Izuku, meanwhile, just tilts his head at her for a moment before returning his attention to Ryuko.

He’s not quite yet ready to forgive Rumi for springing this on him. Then again, if he didn’t want her to do stuff like this, he should have said something back with Mt. Lady, he supposed. And also, if she hadn’t sprung this on him, would he have noticed what Ryuko’s douchebag of a boyfriend was up to before it was too late? He certainly could have saved both Rumi and Ryuko just as easily later on, but perhaps not before the asshole got his hands on Rumi too. And that… that would have signed his death warrant.

As it was, Izuku knew he would have to decide what do to with this man he’d never met, once he was done with Ryuko. Ryuko who was currently kneeling in a puddle of her own sweat and pussy juices at this point, and not just because of how absurdly wet she was.

He continues to rail Ryuko’s throat, fucking her face as he removes every bit of the other man’s essence from her body. He’s quite literally erasing her boyfriend’s mark from her at the moment. In the end… he is the one doing the NTR now, he supposes.

Meanwhile, Ryuko is having the time of her life. Thanks to his Quirk, the switch has been flipped in her head, making her mouth and throat as sensitive as her cunt would normally be, if not more so. She’s cumming hard from this and has been for quite some while now. Izuku honestly is only paying that half a mind. Most of his focus is on removing the other man’s presence from her. Inch by inch, he goes over her body, to be sure it’s all gone.

It's a test of fortitude, remaining rock hard while literally using a special Quirk-enhanced sight to gaze beneath Ryuko’s skin at what lays underneath. But he does it because he cares. Maybe not about Ryuko, at least not on a personal level just yet, but he cares about Rumi, and Ryuko is her friend. For that, Izuku is willing to move Heaven and Earth to help her.

Only once he’s finished and can confirm that Ryuko is completely clean of the man’s influence does he pull his Quirks back and focus on the pleasure of her gurgling throat flexing around his cock. Her wanton moans reverberate up and down his shaft as he pistons in and out of her gullet.

“Glughk! Glughk! Glughk!”

With a lustful growl, Izuku forces Ryuko to look him in the eye again. Her vision is glazed over from the pleasure, but she still hears his next command.

“Here it comes. Swallow it all, Ryuko.”

Ryuko’s one visible eye widens and she nods as best she can. A moment later, he begins to cum. Groaning, Izuku tosses his head back and drags Ryuko’s face all the way down into his crotch. As her nose is buried in his pubic hair, her chin brushing up against his balls, Izuku lets out a rumbling growl deep in his chest.

The Dragoon Hero, meanwhile, does as she’s told. She swallows and swallows, drinking down every last drop of Izuku’s seed. She guzzles away at it, gulping down his cum like her life depends on it. Maybe she thinks it does. He has absolutely no clue what’s going through Ryuko’s head right now, truth be told. He doesn’t know how her boyfriend’s Quirk made her feel, nor how she feels now that his essence has been removed.

What he does know is that he’s just getting started. He’s going to fuck Ryuko silly. He’s going to give her the same treatment he gave Rumi. He’s about to fuck her so fucking hard she completely forgets about that other man. Why? Because at the end of the day, Izuku is not wholly a good man.

A good man might have stopped everything here and explained what was happening. But Izuku had his secrets and he couldn’t explain how he knew all that he knew. But that was fine. He’d done his good deed for the day. Now it was time to reap the rewards.

And to be fair, as he pulls out of Ryuko’s throat and she shows off the last mouthful of his cum by lolling out her tongue before pulling it back in, he can tell from the look in her eyes… she knows exactly what he’s going to do to her next.

And she can’t wait.
