lemme just write this real quick bullshit for u b/c i was already thinkin about it before i got this ask (so if errors, too bad my dude)
“It’s hot!!” you whine loudly.
“You’re hot,” Genji purrs, slipping a hand under your thin shirt. He can’t help himself; you look so good in those jean shorts and that skimpy top.
You’d shove him away, but his cool, metal hand feels great on your skin. The heat is melting your brain, so he talks you into following him (with increasing contact with his cold body) into a shaded alley. One with cool, dark red, brick walls to lean against. But Genji doesn’t let you. Oh, no.
No, he pulls away the plate covering his crotch, a string of precum connecting it to the head of his cock. You hum in pleasant surprise. Genji pulls you close with arms around your waist and the plate in one hand. He slides his cock between your legs, hardening from the contact with your soft skin. He pulls your leg up around his hip and holds it there. Then he works his cock up into your shorts leg and past your panties.
It’s a tight fit, only enough for him to fit inside you and not much else. You hide your face in his neck, swearing softly. But you never told him to stop.
“I bet you want someone to find us. You’re filthy,” Genji whispers, rocking his hips ever so slightly.
You gasp and hold him tightly.
“Stop?” he asks.
“No.”
Genji works his way up to short, punctuating thrusts up into your tight heat, with a few seconds space in between. He enjoys your yelps into his neck. He’s wearing a open-mouth grin behind his mask, panting. The space between thrusts steadily decreases, and your volume increases inversely. The little shit tries to shush you, but you can’t tell him off at the moment. You can only hang on for the ride, digging your fingers and thumbs into the crevices of his waist.
Your last bit of reasoning suggests you shove his scarf in your mouth to muffle your whines, so you do. You forget about the semi-public space you’re in, and he fucks you until you cum on his cock. Then he lets himself spurt up into you.
You two remain like that. Your legs are tired, but you cling to him. You’re worried if he slips out, a mess will slip down onto your inner thighs. He will eventually from going soft, but you stay like this for now.
He sighs happily, rocking your body side-to-side.
“You’re such a good fuck,” he says.
The normally eloquent man sometimes surprises you with offensive language, so you slap his back for it (and everything else that he did to you), and grumble “Fuck you,” around the scarf still in your mouth.
