Frank leaned back on his elbows, head tilted back as he enjoyed the feeling of it. He didn't want to come like this, any more than Billy had wanted to come from Frank doing it, but it was a good, familiar indulgence between them at this point. And it distracted him from the slick-cool touch of Billy's fingers, made sure he didn't get nervous about that. It was hard to be nervous with Billy's mouth on him the way that it was.

He cupped the back of his head and fucked up into Billy's mouth, gently. He liked the noises that Billy made when he got a little messy.
