"Look at me when I speak to you, Potter."
It progresses from there. Severus doesn't know how. He never intended it to go quite as far as he did. But he explores Potter's body, and Potter explores his. He still hates him, except for his eyes, and he can't pretend his hard, male body is Lily's. But it's close enough to something that it doesn't matter.
He doesn't care what Potter does to him, or what Potter wants done to him. The boy seems to have no qualms about demanding things, anyhow. Severus has only one request.
