Specific cursed!Sam fic

[8_letter_love]

I'm looking for a fic that I read a while ago, and I hope one of you can help me find it. The story started pre-series, and went on to at least Season 1. In the story, during a hunt Dean and John were kidnapped, and in order to get them free, Sam had to become a slave to a succubus for a month. Nobody remembered that he had been gone, and I remember that he was cursed into not being able to talk about it, and to only be able to get off from like, complete submission or something. I know that it turned out to be a wincest fic, and Sam eventually killed the succubus. I've been going crazy looking for this fic, so it would be awesome if one of you know what I'm talking about. Thanks!
