For all the bravado Dean exuded when he talked about his rather extensive sex life, Sam was surprised to find that Dean was, for the most part, silent in the sack. A little grunt here or there, maybe a growl when he really got in the mood, but other than that, he stayed pretty quiet. Sammy, on the other hand, couldn’t keep his mouth shut. As soon as Dean would shoot him that look, Sam would be whimpering and squirming in his chair. He’d moan and clench under Dean’s mouth, whether it was sliding hotly across Sam’s chest and neck or closing over one of Sam’s nipples, and Sam would practically scream once Dean’d sink down onto Sammy’s cock. Dean didn’t mind too much, though. Always gave the neighbors something to do.
