Found! Specific fic: Lenore turns Sam into a vampire

[tyger66]

I am looking for an old fanfic where Lenore turns Sam into a vampire in an attempt to show him and Dean that vampires are not all evil (or something along those lines). I remember that Sam went back to the hotel room afterwards, and I think(?) Gordon was still there, so he had to wait. I also believe that he turned Dean into a vampire later and that the story was Wincest, but I'm not entirely sure.

It was fairly long, and I've been searching for it all week with no luck! Does anyone remember this story?
