Holmes arches his back toward Watson, feeling delightfully depraved and at Watson's mercy, which is a sensation he can never quite get enough of. For all of Holmes's general tendency toward dominance, he can't deny a penchant for men in uniform that extends beyond the uniform itself and to what it suggests: a certain strength, confidence, and dominance that is particularly appealing in the bedroom. (And doubly so when Holmes can make those men writhe against him in desire.)

"By all means." His eyes are very dark now, and he watches Watson at his progress, devouring the sight before him. "Indulge your every whim." He has to release Watson's thigh; he needs to let loose some of the tension in his grip, so he busies his hand with stroking Watson's thigh, straying more inward occasionally.
