It's like his fingers themselves are erogenous zones, as Tom's tongue moves over them, and he keeps them there until it's too much, the fingers of his other hand inside his fly and lying against hot, hard flesh.

He doesn't ask permission. He pulls his fingers away, tugs his cock free of his pants, gently pull's Tom's head forward with a hand at the back of his skull.

He doesn't give any instruction. Tom should know what he wants.
