[Oh, and the other thing... the one thing he loved most about watching someone sucking him off had been them watching him back. Dean rolled his eyes up to meet Sam's, worlds of filthy promises in his expression. He didn't have to try for a lusty look, either. The desire was all genuine.]

[Fuck, he had no idea this was going to be so hot, or he'd have gotten Sam in his mouth this morning. It was possible he was about to develop a very serious oral fixation.]
