hi! I'm looking for a fic that has sam and dean as young teenagers when they get trapped by a madman? (i think just a human not a monster) and sealed in a concrete room. there is some food in it but it eventually runs out and they start slowly starving to death. I can't remember for sure if it was wincest or not but I think it might have been? Eventually they are found because they keep tapping on this pipe and someone hears them. Thanks for any help in finding this story! It's been driving me crazy!
