Matt interferes with the delivery of another mysterious weapon and gets hit with something that turns out to be very potent sex pollen. He manages to get away, but by the time he stops to catch his breath in an alley, he's an utter wreck and he needs to have sex or it feels like he's gonna die. And then Karen spots him and sneaks up on him because his senses are overloaded. She's super worried because he's breathing weirdly and twitching and once he sees her, he tries to get away, but then he stops fighting it and just gives in and kisses her and she responds and he hauls her up in his arms and fucks her against the wall. And then on the nearby porch. And several times afterwards. And he's near delirious, but she lets him do whatever he want and it's desperate and rough and.. And obviously, he's still in costume and fully clothed and she doesn't know it's Matt. And after it's over, he's spent and they are both exhausted and he can't even ask if she's okay, because he's afraid she might recognize his voice, so he's only communicates by nodding and shaking his head as he walks her home. And he's absolutely destroyed by guilt in the morning.
Sorry for such a detailed prompt - it doesn't have to be exactly like that!
