Holmes smiles for the briefest of instants and then kisses Watson heatedly, shutting his eyes tight. He could try to analyze why this is helping him not to feel so nervous, nor so skittish; maybe it's because now he's focusing even more on Watson, which had been the initial plan, exploring Watson intimately on a whole other level -- a level that's more important, in some ways. Perhaps it's reaffirming Holmes's confidence.

Regardless, he's quickly forgetting about his insecurities and beginning to have fantasies akin to Watson's. He doesn't think he's quite ready for what Watson had had in mind, but at least he can imagine them without feeling trapped again.

"So my being inside you has become traumatizing now?" he murmurs, teasing Watson, though it still seems slightly... off to be doing that. He doesn't feel the teasing spirit all the way through him yet. "I shudder to think what a longer dry spell might have caused. Is the damage reversible? We would have to start small, I think, and work our way back up."

It's not too difficult to come up with this cover story to make up for Holmes's inability to fully reverse Watson's trauma now, as it were.
