etc
Izuku gets tossed into the past and quite literally crashes into a Younger Shouta, she does her best to keep everything under wraps but Shouta figures it all out pretty quickly. It helps that he has some reasons to want Izuku to stay, namely she slammed into him and his heart was stolen pretty quickly. He's decided that he's going to marry her, and does his best to seduce and romance the tiny 'symbol of peace'- in training.
The entire situation is hell on earth for Aizawa-sensei in the present, who has to deal with the embarrassing and erotic memories suddenly showing up as they occur in the past, especially once Shouta starts seducing Izuku.
2nd Year! Izuku gets tossed 15 years into the past after being attacked by a villain on her morning run, and she quite literally falls out of the sky and lands on a teenage Shouta Aizawa who’s walking with his friends, Nemuri and Hizashi, to school. His friends, the idiots, laugh hysterically as he’s trying to pry this groaning girl off of him.
He finally gets a good look at her face and can feel cupid stabbing him in the back, because no girl has ever looked this pretty to him before. he decides right there he needs to marry her. Izuku careful he asks if he can take her to Nedzu-sensei. He does but he keeps a hold on her hand the entire time, She’s shy and hiding in his back for most of the trip, because she doesn’t want people to accidentally recognize her later on. When they get to the principal's office Izuku hands over her lanyard with her phone and wallet, and Nedzu quickly sees what’s wrong, bids her to go with Aizawa-kun to class 1A for the day and come back to the office after classes are over.
The entire thing is a little mysterious but Shouta is more then happy to spend the day with her, putting her in his chair and stealing an empty desks that she’s in back corner by the wall and he can keep her close to him. When class starts she’s made to go to the front and introduce herself, it’s awkward and she doesn’t know what to do so she gives a careful introduction before quickly hurrying back to Shouta and the desks that he’s pushed together so they can share his books. The day passes quickly, everyone figures out pretty quick that Izuku is a smart cookie, then after lunch is hero training.
Izuku was bouncing with nervous energy as Shouta led her out to the training field and gym by the hand, the teachers had all been given a brief rundown about what had happened to her and were all eager to see what this new student could do. So she got called up to perform a quick quirk apprehension test. Izuku steps up to the plate like a champ, unzipping her track jacket and showing off her battle scars and her strongly frame before dead-lifting a free weight equivalent to a pickup in actual weight, with minor help from her quirk.
Shouta is standing near the front of the class for once, hand pressed against his chest with hearts in his eyes as he watched Izuku easily rise to the challenge with a happy smile and laugh. It’s clear from the look on his face that he’s utterly in love. She had been so nervous earlier, hiding behind him and avoiding being seen or touched by others but here she was, proving that she was a hero in training and completely in her element as tiny sparks of green lighting barely flickered around her shoulders. Aizawa makes a dying keening noise in the back of his throat and Hizashi and Nemuri are silently going into hysterics in the bg over heir friend’s reaction while the teacher is looking at her like "girl who tf are you?” The rest of the class is just startled that shes so buff
The first time Shouta goes to gently grab her with his capture tape, Izuku struggles a little bit cause she thought he was gonna be mean, but he just pulls her in so he can kiss her cheek and Izuku makes this high pitched noise of embarrassment. Everyone who sees the scene is in shock! Everyone thought he was gonna bully her just a bit but instead he kisses her cheek while choking out a demand for a date, (it’s a request everyone can tell he’s practically begging her as he tightens his capture tape around her form)
She’s very confused so she does what she’s good at, and avoids the situation. For her this is horrifying because she thinks he’s teasing her and it’s bad enough that she already had a crush on the older Aizawa now Shouta is chasing her?
After a few days of her avoiding him, Shouta gets pissed and snaps her up with his capture tape, as she’s jogging on campus after school, he drags her into his chest and slams their lips together, attempting to part her lips with his and when she’s stubborn, tightens the tape around her breasts so that she gasps and he can plunder her mouth.
She thinks she’s dying when he pulls back, and a bit meanly goes “You shouldn’t make fun of a girl, please kiss someone you’re actually interested in being with instead of me.” Before shock kinda sets in and she’s left staring at Shouta in horror/want before she notices him licking his lips to get the taste of her mouth back on his tongue. She untangles herself and bolts away, face completely red.
Shouta is left standing there licking his lips, thinking that her mouth tastes like strawberries while his classmates who see he scene are staring at him in horror/shock. They're completely stunned by his forwardness, but he is completely unrepentant and very smug. He’s pleased with himself because he got to taste the inside of Izuku’s mouth first. He stole her first proper kiss, and he was gonna get the rest of them too!
Shenanigans happen and Shouta finds out that Izuku is from the future, that doesn’t matter to him though, he wants her to be his; When they finally get together Shouta while normally relatively discrete, turns out to be completely incorrigible when he wants her,
He pulls her behind the school after classes and leans her back into the wall, hands on either side of her head as he opens her mouth up and leaves her completely breathless. Izuku normally ends up weak-kneed and whimpering after a makeout session with Shouta. She’s always left wanting more as the tall boy pulls away, licking at his lips like he tasted something worth craving. He seems to enjoy kissing her more then he really should, like each kiss is a prize to be won and cherished and Izuku was confused by his glee when their lips met. Maybe she should ask one of his friends? He was so happy because she was willingly giving him adoration and affection with every kiss, it doesn’t help that Shouta is greedy and wants everything Izuku is willing to offer him.
Shouta took her on a double date to the mall, it was fun they messed around, got to pet a couple cats at the cafe and eat yummy food. But Shouta’s hands never really left her, he always at least pressed into her side, most of the time with a hand brushing hers. It riled her up just the slightest bit when after 3 hours he the total time he had spent not touching her was about 20 minutes. It was weirder still because they ended up ditching Nemuri and Hizashi about halfway through the day, Shouta was snickering to himself under his breath and Izuku was mildly confused when he pulled her into an obviously unused storage room and dragged her into his chest. It was quickly cleared up when Shouta ran his hands up her thighs, groaning softly as he buried his hands into the front of her shorts as he kissed her noises away. He sunk his fingers into her pussy and kissed her senseless as he drove her wild. Making her forget they were at the mall and in an empty storeroom as he flicked at her clit with his thumb to make her sob her orgasm.
During lunch one day, Shouta pulls her into a janitor’s closet and turns to her with a wicked smile and a hungry glint in his eye as he kneels down and pushes her up the wall so that he can press his face into her crotch with a loud inhalation. Izuku is beyond red as Shouta yanks her panties to the side before licking a long stripe over her pussy and Izuku suddenly realizes that she’s in for it, this is going to drive her insane. He spends the next 30 minutes with his face pressed into her cunt, sloppily eating her out and watching as she writhed and sobbed for more as he pulled an orgasm or two out of her trembling frame.
When he sets her back on her feet, he surges forwards to kiss her, lips and chin slick with her arousal as she clung to Shouta and let him lick open her mouth for a deep kiss so that could taste herself on his tongue. After pulling back he wiped off his face with the sleeve of his jacket before pulling her trembling form out of the closet so they could get something to eat quickly before classes started again.
The entire time Aizawa-sensei in the present is dead because he keeps gets new memories of him being intimate with Izuku, he keeps popping boners sporadically. Why the hell was his younger self like this?! He could still taste her on his lips and that wasn’t fair! God he wanted her!
The entire situation is horribly embarrassing for him! Like, the first time Shouta drags Izuku into a closet for a makeout session and gets his hands up under her skirt and has her whimpering into his mouth. Older Aizawa is sitting in the teacher's lounge redfaced as his colleges ask about "what memories are you getting now?" and he can't say "the younger me is fingerfucking Izuku in a closet"
Then when Shouta gets his head between Izuku's thighs that first time in the janitor's closet, Aizawa-sensei is completely red for the rest of the day cause he can still taste her on his tongue. God did she taste amazing, and now he's fantasizing about eating her out for hours just so he can keep that taste on his tongue.
