Oh, this one's really vague (in my memory). Sam is kidnapped - I think he's in high school - and held at some sort of secret (government?) facility. He's tortured and raped, spends a lot of time tied to a chair. Some of the torture/rape happens in the dark, so he learns to be frightened of that. I seem to remember that more than one man tortured him. Not sure whether they were demonic.

Can't remember why Sam was kidnapped. There was a doctor overseeing the experiments - he watched many of the sessions through a two-way mirror. Sam never left the one room. Ultimately he was rescued - can't recall the break, the doctor may have finally had a change of heart, but I won't swear to that.

Writing was very intense - just reading the fic was harrowing. I don't think it was Wincest. I don't remember John and Dean being involved in the story much; it mostly focused on Sam.

Any bells? please and thank you.
