This is all wonderful but just... too... not enough. He wants to throw Watson on the bed and relearn him, wants Watson to throw him on the bed and leave Holmes squirming and gasping for more. This angle is insufficient; the pace of Watson's hand only highlights how little Holmes can do in return.

He squirms, pressing back against Watson's growing erection, and he tries to sit up, to break free of Watson's arm.

"This position is most inconvenient," he says, only a little whine to his voice. It's intensely erotic to be held like this, against Watson's chest, and to be stroked so slowly. That's possibly a part of his protest, too, as he's been helpless far too often to settle into it now without being a little restless.
