Hi there!

I need a help finding an old fanfic. The platform was either AO3 or fanfiction.net, probably the latter.

TW FOR GORE but the plot is Sam made a deal with this man where has has to give some of his blood away to the man once a week to save Dean from hell. The man gives the blood to this vampire, Sam passes out from blood loss in an alley way, Dean finds him, and he goes to a hospital, but plays it off as nothing. Dean follows him giving blood and Lilith shows up.

If anyone has any idea what fic this is, please let me know. Thanks so much <3
