lf specific Sam/Dean unrelated creature fic

[ikabod11.livejournal.com]

The fic I'm looking for features an unrelated Sam and Dean. Dean is a hunter and Sam is a photographer who runs a website selling research about supernatural stuff to hunters. They meet on a case and hook up, but Sam won't kiss Dean during sex because he was turned into some kind of were creature and he was afraid Dean would be able to tell by kissing him. After the truth comes out they go their separate ways, but then Dean tracks Sam down and a happy ending is had by all.

Hopefully this will ring a bell with someone.
