Broken - phantisma
4.5 stars. This is probably the most angst I have ever read in a fanfic and I have read a LOT of fanfic. A long dark fic full of abuse and angst but very well written and plotted. Only for lovers of the DARK..
Sam rescues Dean from slavers that have owned Dean for a year and conditioned his every response through violence, rape and mind games.

"Sam?"
Dean's voice stopped him and he turned.
"I still belong to you... don't I?"
Sam swallowed the lump that lodged in his throat and nodded.
"Always, Dean. Always."
