Castiel & Leonard Snart
"You are positively delightful and I am thrilled to get to end the night with you."
Leonard had never understood the rationale behind self-imposed monogamy. He loved sex the way he loved life. There was never a reason to skip out on it just because someone else thought he should. If he ever chose to share his body with only one lover? It would be because of a shift in his mentality he couldn't imagine being anything less than completely life-altering.
Given that death hadn't changed his opinion on sex, Leonard couldn't imagine what would.
"I'm versatile. We can try both options out and see which one we like best. Deal?"
