Kirk/Spock mindmeld fic

[maosandchayhem.livejournal.com]

Hey guys, you have no idea what a relief this comm is! I found this fic maybe a month, month and a half ago, and loved it. But I've since forgotten the title and author, and I can't seem to find it for the life of me.

So, I'm looking for a TOS-era fic, in which Kirk and Spock, for a reason I now forget, had to initiate another mind-meld. And for whatever reason, Kirk is to be the one that takes the lead on it. At first it's all very abstract to Kirk, but then he realizes it feels pleasant, and he finds himself thinking about sheets and lube.
Eventually the two wrench out of it, and Kirk is in shock as he realizes he has essentially initiated mental sex with Spock. Then he realizes that both he and Spock are physically aroused, and of course real sex ensues.

Thanks in advance!
