fic with vulcan retractable penis?

[miscellanium]

hope that subject got your attention, haha.

there's a spock/chapel fic i can't seem to find. it wasn't very long at all - might have been set during the amok time episode? - and spock's genitalia were retractable. this was explained by the desert climate of vulcan or something like that. i feel like the fic was a companion to a k/s or mc/s piece, but i can't remember as much of that one. for some reason i thought it was archived by the foresmutters project but it's not; i want to say it's an early fanzine fic but it could be more recent, i guess. the "vulcan genitalia" page of fanlore has no hints, alas.

any help and guesses will be much appreciated!
