This is just lovely! The little I know about Star Trek comes from the latest movie, and the only thing I liked in it was Spock. He reminded me of Snape, actually. So, Spock-Snape makes perfect sense to me, and I love how he tries to hide his crumbling poker face behind his cards. *g*
Hmm, I rather suspect Harry’s fully aware of what’s going on and more than eager to strip in front of Snape as Spock; it is his fetish, after all. Your Harry is very attractive, BTW.
The colouring is beautifully done. Snape’s shirt, Harry’s underpants and the warm skin tones look wonderful. Most of all I adore the obvious mutual attraction between the two of them. *happy sigh*
