Denji almost starts when Shidou cums, surprised it seems to be that bite that sends him over. Eyes wide, he watches as Shidou’s dick pulses out its load, stroking Shidou through his orgasm. He blinks at his jizzy hand like it wasn’t the most obvious conclusion possible, and wipes it on his shirt. Which he’ll definitely regret later. His brain’s working less than even usual.

“Augh,” Denji gripes to the kiss, but besides that and a scowl, he doesn’t really complain—especially when his dick is stroked again; his gaze immediately goes a little vacant and his body untenses, making a low sound of pleasure. Denji’s too easy.

“Thigh fuckin’…”

He thinks he’s seen that before. He’d never thought about it with a dude. Or rather, never even applied that as an activity they could do together.

But wait. He already had something in mind, didn’t he? Ugh, and he’s gotta be the one to say it. He bites his lip, face going red as he struggles to get the gumption to get it out.

“Actually, could you play with my ass?”

Denji feels like a traitorous convert. Not his fault it apparently feels awesome or something.
