Anticipation jolts up his back before smoothing out into a quiet eager hum in his whole body as Ken jerks his fingers out of him. Best he can, Chikusa tries to calm his own breathing and kneads his fingers harder into the fist he’s made up against rough brick. He can feel his cock literally twitch when Ken grinds up hard and fast at his ass, but it’s not what he wants. His lips part, words on the tip of his tongue to tell him to stop messing around-

A quiet gasp as something slides into him, graduating fast into a whimper that rolls out of his mouth. If it’s the thrust that fills him up so completely or Ken’s teeth laying claim to his skin again, Chikusa can’t say. It doesn’t matter. Fingers slip and drag nails across Ken’s scalp as he presses back against him, gulping down air to calm the excited ache in him.
