Derek can feel how close Barry is and he lets out another needy whine, clutching tightly at the backs of his thighs and sucking harder, opening his mouth deeper. Barry's words make Derek's eyes widen for the briefest of moments before they go half-lidded again, and his cock jerks and leaks as he lets out a moan like a purr around Barry's cock.

His fingers glide across Derek's face, thumbs pressing into his cheeks where they're hallowed around Barry's cock. Derek stares up at Barry in awe, lashes fluttering at the gentle touch of his fingers even as his cock slides in deep, nudging the back of his throat in a way that makes him reflexively swallow before sucking harder, like he's trying to keep him inside.

Barry's voice, and the things that he's saying, make Derek tremble all over at he looks up at Barry with his pupils blown wide and ringed with crimson. He pulls off of Barry's cock just long enough to let out a shuddering gasp and nod. "Yes. Please, Barry."

And then he takes Barry's cock into his mouth again, sucking him down deep in a way that's more determined, designed to make him come.
