He hadn't been expecting that Watson would be able to resist making noise for too long -- that simply isn't how Watson operates -- but to see him cave is certainly a satisfying experience. His hand settles into a steady rhythm, familiar as he is with Watson's body; it's nearly second nature now.

"What was that?" he teases, a dark glint in his eye. "I didn't quite hear you."

He entertains himself with more light, teasing attention to Watson's cock, more interested in working him up than giving him any relief at all, and after a few moments he switches his attentions. He moves his kisses to Watson's inner thighs, biting as hard as he dares to without seriously harming Watson.
