Shidou's cock is getting harder by the second; soon, he's at full mast, making an obscene tent in his briefs. "Fuck, look at you, all pretty and blushing," he croons, lips against Denji's reddened cheek. "It's hot. You're hot. Your cock's hot. Fuck"

He really is a slut for cock. Wrapping long fingers around Denji's member, Shidou begins to pull on it, wanting to get fully hard. "Hot?" he supplied the unspoken word. "Yeah, it is."

Shidou had kissed girls before, and aside from a grope to a boob which only cemented he wasn't interested in the opposite sex, but he knows it's different. Some girls can be pretty hard, but most aren't. He wonders if it's social conditioning or just genetics. Either way, it's not something he's interested in right now, not when he's got a nice dick in his hand.

He kissed Denji on the mouth again, sliding his tongue inside as he threw a leg over his lap while he kept stroking. "Wanna lay back or watch me?" he asked.
