Our Favorite #1 Hero is WEAK to neck kisses.
He can’t handle it. Izuku, THE top hero in Japan as you know him, gets hard as soon as he feels your breath on his neck. And it’s never the soft tent he gets in his pants that easy to get rid of, of no. This man gets the boner that’s completely unbearable to the point where his clothes pose a problem.
He becomes desperate after a making out session that includes a little necking. If you’re sitting on his lap, you’ll feel his cock pressing right between your legs. Don’t you dare pull away, he’s already got his heart set on pinning you against whatever surface is available and punishing you for making him so needy.
He’s a whimpering mess if you kiss his neck in public. At dinner with All Might, Bakugo, Todoroki, and some other friends and you decide to give him a soft little peck on the neck? Get your ass in the bathroom because you know what you did. He can’t function when you do things like that, it’s frustrating. Heaven forbid there’s no easy way to escape because you’ll just watch him squirm around and try to say anything that isn’t related to what he’s going to do as soon as you’re alone.
He always asks you not to do it in public but he never enforces any rules on you. Especially because he likes to show off any marks you make and subtly brag about them to his friends.
