Priestly almost—almost—stops to correct the name, because that's just the kind of thing he does, but he's way too into it now. He doesn't want to lift his head to do more than breathe, and maybe once he'd been intimidated by this but he's good with his mouth and he's good at this, too. He doesn't stop. And he doesn't touch John's cock either, at least not more than the occasional brush or bump. This time, he gets to make it last.
