The world needs more IzuMomo, so I am here to deliver. Hope you enjoy!

Izuku knows that Momo is the more adventurous one between the two of them when it comes to sex. He's not surprised. Momo spends so much time being the perfect student - always prim and proper, always polite, always respectful to her superiors - and no one can come away from that unscathed. All the pent-up frustration has to go somewhere, and Izuku finds that it goes straight to her libido.

Their study session starts off innocuous enough. They choose a spot in the back of the public library, a circular table hidden away from most of the other patrons who'd enter that day. A comfortable silence envelops them as they work individually - she breezes through their English texts while he mulls over some calculus that he really should've done the night before. It's when he's about halfway done and stuck on a particularly nasty problem that he looks up to ask for her help.

But the look on her faces says that they're not about to get much work done.

Izuku fights back a pleased shudder as her eyes move from his hands to his face, and from the way she worries her lip and the pleading gaze she directs at him, he can tell she's been watching him work for some time.

He fights down the flush that's no doubt making its way up his neck. "Ah, Momo, could you help me with this problem? I'm having trouble solving the integral…"

Deep down, Izuku knows he's still the boy who's elated to even have a girl breathe in his direction, but being with Momo has given him some semblance of experience, and he's more than willing to drag this out as long as he can stand it.

She picks up on it - as she usually does - and allows herself a knowing smirk before cowing her face back to a neutral expression. "Of course, Izuku." She moves her chair close enough to him that their shoulders are touching and his arm runs along the length of hers. "Now, show me where you're having trouble."

He obliges and pretends he doesn't notice the way her breath feels against his neck, pretends he doesn't notice the way she presses her chest on his back, pretends he doesn't notice her and everything she is. Aloof as can be, he runs through the problems, and she really does assist him, but the answers are coming fewer and farther between, and her breaths are picking up, and he knows it's only a matter of time before she caves. Izuku fights against the erection he feels growing in his pants and wills himself to hold on just a bit longer.

It pays off. "Izuku…" she whines. Her thighs are rubbing against each other and her hands are caressing his legs. Whatever resistance he managed to put up crumbles as their lips meet. All thoughts of his calculus are replaced by the way she feels pressed up against him, the way she moans into his mouth oh-so-sweetly. He makes some noises of his own, but the two of them try to stay quiet enough that no one will decide to check up on them for disturbing the peace.

Before she can pull away, he's already sliding a hand up her shirt and under her bra to take her right tit in his hand. She gasps as he starts to tweak and twist her nipple and it's music to his ears. She takes his remaining free hand and shoves it up her shirt roughly, and he begins work on her other tit. His ministrations turn her to putty in his hands and he hasn't even made his way to her cunt yet - she must have been horny all day, then, he rationalizes.

While he loves the feeling of her tits in his hands, he knows he's got to get the show on the road if they're ever going to get back to work. Reluctantly, his hands come away from her tits and one snakes its way down her body before stopping at the waistband of the skirt she's wearing. He barely hesitates before lifting up the waistband and moving his hand inside of her panties.

Momo moans as Izuku glides his finger in a lazy circle that traces her labia. At any time he could plunge it in or rub her clit, but he wants to see how long she'll go before her arousal turns to frustration. As it turns out, not long - he barely gets through a minute before she's a blushing, panting mess. She stares at him meaningfully, but he refuses to acknowledge the gesture and continues his teasing.

With another needy whine, she leans over to his ear. "Please, Izuku." She kisses his ear and lightning shoots up his spine. "Please, just do it. I need this, please, I'm begging you - "

She doesn't get to finish before he shoves two fingers in her pussy with ease. "Momo, you're - you're really wet," he says, and she responds by whimpering again, shoving her head into the crook of his neck. Izuku has to bite back a gasp of his own as her hands eagerly pull his fly down and yank his cock out in one swift movement.

Before he knows it, she's jerking him off furiously, and it feels so good that he nearly forgets he has a job he's supposed to be doing. Izuku's fingers resume their movement slowly pumping in and out of Momo's cunt.

"Momo," he begins. He's done this part so many times it's become second nature. "This feels amazing. But we could…" Izuku makes a show of checking their surroundings - left, right, around, anywhere that another person could be hiding or browsing. "...we could get caught."

As always, her breath hitches as soon as he sounds that last word. "Doesn't it make you nervous, Momo? Anyone - " He has to pause to stop an errant moan from slipping out, but she knows the effect she has on him. "Anyone could see us right now, doing this. Two students, two heroes in training, some of the best students in the class." She bites into his shoulder from where her head is, and he knows she's trying so hard to hold back.

Truth be told, the whole thing turns him out just as much as it does her. No one in 1-A would think the two of them - innocent little Izuku and perfect student Momo - would ever be capable of reveling in such debauchery. It's wrong, illegal even, but he can't bring himself to care.

"This - this is wrong, Momo." He puts on the act of a concerned boyfriend even as he shoves a third finger inside of her and she continues to stroke him at a lightning-fast pace.

"But I - " She hisses and bites down on him again as he angles his fingers just right in the way he knows she likes. "I want this, Izuku, I want this so badly."

The combination of her strokes and her moans and her everything is enough, and Izuku feels his climax building up. "Momo, please, I'm about to cum. Is that what you want?" He turns up the drama as best he can without alerting anyone to their activities. "Do you want me to - to cum, right here where anyone could see?"

He knows the answer, of course, but he still manages to hold himself back until she nods and responds breathlessly: "Yes, yes, yes," she says. "Please cum, I want to see it." With a muffled groan of his own, Izuku erupts into Momo's hand. Spurt after spurt comes out, and she manages to catch every single one. She licks the cum off of her hand desperately, and Izuku knows what's coming as she rocks herself against his fingers faster and faster.

"So much cum, Izuku, you came so much - it must've felt so good to…" She's panting again, quicker and quicker and quicker. "So good to… so good to - !" She nearly yelps, and Izuku feels her clench around him. Her legs start to shake and she has to - once again - bite down on his shoulder to weather the intense orgasm that rocks her body. Even still, a few almost-loud-moans slip out as she rides the wave. Then, after what must've seemed like an eternity to her, she collapses bonelessly against his side.

He pulls his fingers out and licks them much the same as she had done, just less frantic. Once he's done, he shoves his cock back into his underwear before zipping up his fly, and he does his best to make him and Momo look presentable. To the discerning eye, it might still be obvious what they had done, but a passing glance would more than likely dismiss them.

Then it was time to get their studies back in order. Momo liked to be on top of things, so there was no way he wanted to disappoint her. Their little diversion had been nice, but it was just that - a diversion. It was time to focus once more.

"Alright. Let's get back to work, then…"

"Izuku."

He jumps, not expecting the sudden, surprisingly stern interruption. "Y- yes?!"

Something is turning over in her head, he can tell, but he doesn't know what it is. Her gaze is intense, and he swears he's about to start sweating before it softens and she eases up the pressure. "...Let's rest a bit." And with that, she closes her eyes and droops back to her position snuggled against his side.

He's nervous, of course - they have work to do! - but instead of working himself up, he allows himself to be lulled into sleep, and he dozes off right after her.

They don't wake up until a few hours later, at which point it's a bit too late to study.
