Looking for some specific stories if anyone can help;

1) A really long shapeshifter/sam story. Sam gets captured by a shapeshifter who fucks with his head by beating, raping and drugging him while he looks like Dean, John and Jess. It was about 50 chapters long and a wip when I saw it.

2) I think it was a really short one, Castiel and Uriel were keeping Sam as a pet, ostensibly to train him to not be evil and they treated him like a dog.

3) Any Sam/Gordon or Sam/Henrickson fics, the darker the better!

Thanks!!!
