Kingdom Hearts, Cloud/Riku, wingsex, sensitive skin
The wing is a sign of the darkness that rests in both of them. At first, Cloud won't let Riku touch it, won't even let him look at it.
"But I think it's sexy," the boy says, kissing down Cloud's bare chest, clever tongue circling a pink nipple. He insists on it, begs for it, until finally the man relents, allowing him to run his fingers up and down the leathery skin, trace the curving claws gently.
Riku loves the sight of the giant wing curving over the two of them when Cloud fucks him, on his back, knees pushed up to his chest. He moans and writhes, clenching his body around the biggest cock he's ever had inside him. His hands creep their way up Cloud's back, massaging the place where his wing meets his shoulder, loving the way it makes the man whimper, makes him snap his hips harder.
When Cloud comes, the giant black wing flaps, like its trying to lift the two of them into the air. Riku shivers as the breeze caresses his hot, sensitive skin. He wraps his legs tighter around Cloud's waist, doesn't let him stop.
