Summary: Part 2 of Sex Quirks. After getting checked over by Recovery Girl, Midnight and Izuku part ways. Midnight to explain her new circumstances and Izuku to go workout and clear his mind. When Nejire happens to overhear Midnight's explanation, she can't help but be tempted into 'investigating' herself.

-x-X-x-

Nejire Hado perks up when she hears the sound of someone exerting themselves physically in the gym up ahead. At the same time, she slows down a bit, going from a brisk walk to almost a crawl as she gets ever closer to the Gym doors.

Deep down inside, Nejire knows she shouldn’t be doing this. She knows if she goes through those doors, she might wind up doing something… regrettable. Rushing here after she overheard Midnight talking to other faculty about a new student with a Sex Quirk who put her through her paces and caused some… positive but irrevocable changes to her body had been impulsive and downright reckless.

Nejire knew all of that… but she couldn’t help it. Technically, the bluenette’s own Quirk was not a ‘Sex Quirk’. At least, it wasn’t officially labeled as one. But personally, Nejire felt like it should have been, especially because of the side effects it had on her libido. Sure, it might not be a directly sexual Quirk, but the increased energy and stamina she’s developed thanks to her Quirk means that none of the boys she’s ever slept with have been able to truly satisfy her.

She’d tried. Really, she had. But after a certain point, Nejire had just given up on men, because frankly she’d started to feel worse and worse about having to fake orgasms, especially with her last ex-boyfriend, Miro.

It’d been a while since Nejire had gotten any outside of her toys and fingers, and those weren’t good enough in an entirely different way. While powerful enjoy toys COULD satisfy her in a way men couldn’t, the lack of a human connection, the lack of a real dick… it meant that she was left disappointed and unfulfilled in a different manner altogether.

But maybe… not anymore? Finally reaching the Gym Doors, Nejire takes in a deep breath… and then pushes inside, steeling her resolve. Whoever this student with a Sex Quirk was, they might need her help just as much as she needed theirs, especially if what little she’d overhead from Midnight was anything to go off of. And one way or another, Nejire was going to find out.

“Hello?”

The young man is working out when she comes in, and it’s obvious he’s been churning through the machines at a rapid pace long before she arrived. Heh, seems like he had a deep need to work off some energy, didn’t he? Ah, but just looking at him… Nejire can tell it wasn’t good enough.

He's still frustrated, still brimming with energy, with the potential to bend her over and wreck her sill- Nejire bites down on those thoughts, even as the young man looks up at her with wide eyes.

“Uh… h-hello. Sorry, I thought there wouldn’t be anyone in here. If you need to use the place I’ll get out of your hair…”

Smiling, Nejire shakes her head and clasps her hands in front of herself.

“No, that’s fine! You definitely shouldn’t leave on my account. I’m Nejire Hado, Third Year!”

“Ah… Izuku Midoriya, First Year…”

He still looks like he wants to leave. He also looks like he’s trying not to stare too much at her body. Nejire… Nejire feels her reluctance fading by the moment. He’s just too cute and she wants to eat him right up.

“Izuku… why don’t we spar, you and I?”

“Wha-? I’m not sure that’s a good idea…”

“Oh come on! You’ve got energy to burn, don’t you? I know a little something about that thanks to my Quirk. Using these machines, for all that they’re rated for Strength Quirks, only gets you so far. Sometimes to really blow off some steam, you need a proper fight. What do you say?”

Flushed, Izuku considers her offer for a long moment before slowly nodding.

“A-Alright.”

Hook, line, and sinker. Nejire feels a little bit like a predator circling helpless prey, even as she and Izuku move into the sparring ring at the gym’s center. She is, after all, years older than him. So really, this isn’t even fair. That’s why she doesn’t go all out from the beginning, starting off somewhat slow and gentle to get a feeling for how Izuku operates. After all, if he has a Sex Quirk, the chances of him being much of a fighter seem pretty low.

To her surprise, he’s tougher, stronger, and faster than he looks. Nejire actually has to quickly adjust her speed and strength and stop holding back, even as the spar continues on. She quickly realizes that Izuku is no joke. He’s probably not even going at full strength given this is just a friendly spar, and yet she has to take him more seriously than half of her fellow classmates.

Still, the years of experience she has on her and his unwillingness to truly hurt her ultimately allow Nejire to get the upper hand. And once she has it, she just makes sure Izuku is already on edge and pent up before getting him on his back and pinning him down.

“Ah… seems like it’s my win, Izuku~”

Blinking up at her, Izuku blushes at their position.

“Y-Yeah… I guess so. Good spar, thank you for the lesson Senpai.”

Nejire grins at the title. She likes the sound of it. Just like she also really likes the feel of Izuku’s bulge against her crotch as she grinds down. Izuku’s eyes widen at the sensation, and an involuntary groan leaves his lips.

“Nejire…”

“Oh? What’s this? It seems like you have something for me, I-zu-ku. Did I cause this? Well, I’ll just have to help out, won’t I?”

“W-Wha…”

Leaning in close, Nejire gives Izuku a blindingly bright smile as she rubs her tits against his chest and her crotch against his bulge.

“I heard you have a Sex Quirk, Izuku. I just so happen to have a Quirk that makes it hard for any normal man to satisfy me sexually. Seems like we were almost made for each other, doesn’t it? So… just let go. And let’s feel good together.”

Was it the best attempt at seduction anyone had ever done? Probably not, but Nejire wasn’t some trained seductress like say, Midnight. Still… she can tell it works as she sees the uncertainty and hesitance slowly melt from Izuku’s gaze. And from there… things get fun.

-x-X-x-

PLAP! PLAP! PLAP!”

“Oooooh~ Nnnngh! H-Harder! Oh yes! HARDER!”

From the moment the beautiful Senpai had entered the gym, Izuku had been on edge. Not because he thought she had bad intentions, but because she was drop dead gorgeous and he still hadn’t really managed to calm down his own freshly awakened libido. After what happened between him and Midnight, Recovery Girl had done an examination on the two of them and taken some samples for study.

Meanwhile, Midnight had told him she needed to go and explain to her fellow teachers what had happened and why she now looked like she was in the absolute prime of her life. She’d said she would be telling Eraserhead and Present Mic first, so Izuku wouldn’t have to worry about explaining things to his Home Room Teacher.

In the meantime, Midnight had suggested one of UA’s gyms that apparently didn’t get much traffic for him to go and workout solo for a while until she came and got him.

Izuku had been doing just that when Nejire walked in, and from the moment that the blue-haired woman had shown up, he’d been afraid of losing control and hurting her. How she’d talked him into a spar despite his anxiety, Izuku still didn’t know.

And yet… well, one thing had led to another and here they were. Jackhammering down into Nejire from above, fucking her sopping wet pussy for the umpteenth time with her body bent in half and her weight on her neck and shoulders, Izuku grunts and picks up the pace at her instruction, pounding her cunt like there’s no tomorrow.

He’d tried to resist at first, but she was just too hot for words. In the end, he’d succumbed to her seduction and let his natural instincts takeover. That had been twenty minutes ago, and Nejire had already cum three times while Izuku came once.

“Yes! MORE! OH FUCK, I’M CUMMING… I’M CUMMIIIIIING!!!”

Scratch that, four times. Izuku groans as Nejire’s pussy walls clench and squeeze around his pistoning cock. As soon as she’s done orgasming, he switches up positions again, spinning her over onto her face and knees so that she’s face down, ass up in the center of the sparring ring.

Grabbing hold of her ass cheeks with both hands, Izuku squeezes them harshly, only prompting further wanton moaning from Nejire as he slams into her pussy time and time again from above.

“Y-Yes! M-More! You’re going to ruin me, Izuku! You’re going to ruin me for other men! And you’re going to ruin other men for me! But I don’t care! I want it! I love it! Gimme, gimme, gimme!”

Nejire had seemed like such a nice Senpai too when they’d first met. But either that had been a mask, or Izuku and his Sex Quirk were more of a corruptive influence then he’d first thought. Still, he couldn’t stop now. He can’t hold back, even as he cums inside of Nejire again, and she cums right alongside him.

Switching up positions once more, this time he puts her on her back and folds her legs up along her body in a consummate mating press. Gripping at her ankles for handholds, Izuku basically does pushups in her gushing, creampied twat, fucking her from above as Nejire’s eyes cross and her tongue sticks straight out of her mouth.

The blue-haired young woman’s breasts bounce all over the place, and her red face makes it clear how much she’s enjoying herself, even if she can no longer seem to find the words all of the sudden. The squelching noises of his cock pistoning in and out of her pussy also make it clear that even if Izuku is corrupting her, he’s also making her feel really, REALLY good.

The next time she orgasms, Izuku moves them into doggystyle and reaches out. One hand fists in Nejire’s blue hair, while the other slides down and around to her chest, groping and squeezing one of her breasts quite aggressively. She squeals and mewls, shrieking and moaning practically nonstop, and all the while, Izuku just keeps pistoning away. He can’t help himself. He has to fuck her until she can’t take it anymore. It’s the only form of relief he has available to him at this point.

Truthfully, he’s not sure how long it goes on for. An hour? More? But one thing is certain. When all is said and done, Nejire has been fucked unconscious and Izuku has given her half a dozen creampies.

As he pulls out of her thoroughly stuffed cunt for the final time and rises to his feet, Izuku can’t help but stand there, staring down at what he’s wrought. The expression on Nejire Hado’s face is one of pure ecstasy and bliss, so that’s good… but at the same time, she’s sprawled out with her limbs at all angles, covered in sweat and fluids, clearly entirely broken from their session together.

He thinks back to what she’d said before she went mostly nonverbal. About him ruining her for other men and ruining other men for her. Izuku hopes that was just… well, he hopes that was just dirty talk or something. He doesn’t want her to become obsessed with him or anything like that. She has her own life after all, and this fling while fun was probably a one time-

“Izuku, I- oh dear.”

Whipping around, Izuku blushes as Midnight comes racing into the gym, only to stumble to a halt when she sees what awaits her inside. Biting her lower lip, the teacher looks from Izuku to Nejire and back to Izuku.

“W-Well… look, before anything else, I want you to know this is my fault, Izuku. I shouldn’t have left you alone. You didn’t do anything wrong.”

Izuku stares in confusion at her, a pit growing in his stomach.

“… What are you talking about?”

Midnight winces and then sighs before sauntering over… and dropping to her knees in front of him. Izuku stares blankly as she begins to clean his cock up with her tongue, answering his query between licks and sucks.

“Mm… well, the results are back from, nngh, Recovery Girl. She, mm, discovered something rather… big.”

Midnight smiles coyly at that, making Izuku flush.

“Namely… mm, well, you’re pretty much guaranteed to, mm, knock up any girl you, nngh, creampie.”

It takes a second for Izuku to process Midnight’s words among all of the pauses in her speech. When he does, his eyes widen and he looks to Nejire immediately. Then, he looks to Midnight, who gives him an apologetic grin.

“Yeah. I’m pregnant. And… she probably is too. I never should have left you unsupervised Izuku, so like I said don’t blame yourself. It’s my bad.”

Despite her words, Izuku still feels horrified. He hadn’t… he hadn’t intended for this to happen! Has he just ruined Nejire Hado’s life on their very first meeting?!

“… worth it…”

Both Izuku and Midnight pause and look over at the seemingly unconscious blue haired Third Year. Slowly, Nejire raises her tired head and gives them a weak grin and a thumbs up.

“No complaints. No regrets.”

Then, without missing a beat, her head falls back again, thankfully just smacking into the relatively soft sparring mat under her as she falls unconscious once more. Izuku stares for a long moment at the downed Third Year… before having to look back as Midnight begins to take him deeper into her mouth by the second.

Looking up at him, Midnight bobs up and down on his cock a few times, going all the way to the base before finally pulling back off with a pop as she gives him a grin.

“In case it wasn’t abundantly clear, I agree with Miss Hado, Izuku. It was one hundred percent worth it. Don’t worry… you’ll make an excellent father~”

Izuku’s face has to be bright red with how hot it currently feels. He couldn’t believe what he was hearing. And yet… well, no harm no foul right? If Nejire was happy, if Midnight was happy… then he was happy to. Even if he was a little young to be a dad… well, he had always been a fast learner. He’d be the best damn father that had ever lived.

For now though, such thoughts of the future are thoroughly interrupted by the present. Midnight is getting more and more enthusiastic, and Izuku… well, even after fucking Nejire silly, he’s still ready for more action. From the way Midnight is going about things, he’s going to get it too.

Excellent.
