It's funny-- I feel weird reccing things directly to specific people because what if I am wrong and they don't like it? (There are rare exceptions to this, where I know a story will exactly hit someone else's tastes. But those are very specific unusual occassions.)

Anywho, I shall rec anyway. *^_^*

Pray Your Gods by blue_soaring. Dean's POV when his year is up, but definitely a story about the two of them and the lengths Sam will go to. Wincest, spoilers through S2.

He Sleeps in Ruins by 1shotjunkie. Very Sam centric, but probably not what you'd usually read. It's Sam/Jensen, but you should give it a shot anyway even if you don't like RPS. You can pretend Jensen is just a guy who looks a lot like Dean. *^_^*
