"Wow..." Billy takes a moment to just look at Frank, appreciate the expanse of skin exposed. He doesn't care about the scars, and if the murder one worries him... well, he'd seen Frank in a uniform already. It isn't that much of a surprise that it'd be there. He also isn't the first person with that particular sin down here he'd seen.

"You got locked in the room with a knife too, huh?" Is about the only remark he makes about the scar.

His hands move over his chest, careful to avoid the healing wound while he drags his hand down over Frank's chest and stomach, slowly working his way down.

"Too late, I already said it," he teases against his lips, chasing him for a proper kiss. After though, he leans up to speak against his ear, "Or I could slip down on my knees for you right now."
