"John..." He looked the half demon over again. "Have you never seen another.. man before? You are.. huge." Sherlock gulped. God, how he wanted to have that in his mouth, or... well anywhere, really.

"Every part of you is perfect. I wasn't lying when I said that." Sherlock nibbled carefully at his neck, not using his fangs so he wouldn't draw blood. Every part of you. Every scar tells a story and every tattoo means something.

Sherlock ground down against John again, "You are perfect, and you are mine." He didn't even have to use the Thrall for that.
