Though he might wish to draw this out as long as possible, that was just not realistic and he knew that. Besides, Watson could not entirely suppress the moan that came to his lips at the touch on his own cock. Tangling his fingers with Holmes's, he began a slow stroking, not exactly in time with Holmes's thrusts but at a sort of complementary pace.

And after that, it was only so long that he could last. He could feel his orgasm build up on him, inevitable and on the horizon. Though trying to stay in the moment, trying to last, Watson could feel everything begin to crash. The sound he made as he climaxed was more than a little desperate, drawn-out and soft.
