Looking for specific wincest? fic

[kruel_angel]

I read this story a while ago, but all I can remember is Sam gave into his powers and I think its wincest, not really sure. There's a scene at a church where Dean is at and its surrounded by actual hell-fire and Sam can walk through it because of his abilities. And I also think there was Jake, the one from the season finale in this story too. Can anybody guess? Thanks so much!
