Hello!

Are there any really awesome fics in which Sam goes darkside to save Dean from hell? Full on anti-christ would be great, but even Sam just committing pretty morally ambiguous actions to save Dean is fine, too, but wincest (even if it's non-con or one-sided) only please with NC-17 or approaching rating.

Rec lists, delicious accounts, and self-recs are more than welcome.

Thank you!
