Oh god, the praise.. he loved the praise.. he loved being told that he was a good boy. Between that and the idea of trying to suck off John, being fucked by a giagantic cock and having his movements make him stroke himself, it was all just too much.

"AHHHHHHH!!!" Sherlock threw his head back and howled His whole body convulsed and he screamed again when John slammed into him again, almost sending him off the bed.. His seed painted the sheets under him while John came and came and came, filling him, going beyond filling him, until there was no room and it was leaking out around John's cock, but he was still coming. And Sherlock was still orgasming, the most intense he had ever felt. He wasn't even sure he was going to be able to stay conscious, he was seeing stars, it was so intense.
