Though he can't explore Watson's body the way he'd like, this is more than an adequate brief summary of Watson and what he's been missing in the past three years. The hands in his hair are wonderful, and if he were a younger man, that coupled with the sounds Watson's making now might be enough on their own to bring Holmes's cock back to attention.

Remarkable, that they could spend three years apart and still find themselves here in less than twenty four hours of being reacquainted. That they fall so easily back into each other's arms, can find comfort in the push-and-tug of the power balance of their relationship -- it all speaks to the strength of their bond.

He finds a rhythm, but he's far more intrigued by the movement of Watson's hips. After Watson's delicious display of dominance in the tub, Holmes is fairly eager to see more of that now, fairly eager to put himself in Watson's hands, to be reclaimed. He looks up the line of Watson's body to see if he can catch his eye. He slackens his mouth and tugs Watson's hips, encouraging him to take control.
