Looking for K/S Fic

[psych-nut.livejournal.com]

I'm looking for a Kirk/Spock fic that is probably several years old, and unfortunately I can remember very little about it. From what I can recall, Kirk & Spock are on an inhabited planet, either on leave with the rest of the crew or as part of some official mission. K & S have sex (maybe in some kind of hotel?), during which Kirk touches Spock's ears and eyebrows. I think this makes Spock assume Kirk was turned on by the alien-ness of Spock and that he only wanted a one-night stand, which isn't the case. It ends up with the 2 of them together in a happy ending.
