My favorite Star Trek K/S slash fics.

I made this list mostly for myself, to be able to get back to my favorite fics without much searching. I'll be glad if someone else finds it useful.

TOS

Beautiful and classical:


Shelter by Leslie Fish
Spock suffers a head injury in a shuttlecraft
accident and reveals more than Kirk or McCoy expected. Originally
published in the print fanzine “Warped Space” XX, October 1976.
"Shelter" was the third K/S story ever published. I wrote it
specifically to support the K/S faction in Trek fandom, which was coming
under fire at the time.

Desert Heat by Gayle F
The
first story of what became The Cosmic Fuck Series. This is a pon farr
story. The first appearance of the double ridges. Probably completed in
1976. First published in The Sensuous Vulcan.

Communication by Jenna Hilary Sinclair Rated: ADULT (NC-17)

Spice by eimeo Rated: ADULT (NC-17)
It’s a question of biology. Vulcan biology.
The problem with falling in love with a member of an insanely private species is that it just might take you the best part of a five year mission to work out that the feelings are requited. And then you might discover that he’s already decided that the two of you can never be together.
And what are you supposed to do if he won’t tell you why?
