Gray
Heart Shaped Balloon by @winsive

Sam and Dad are fighting. No surprise, but it's the weekend before Valentine's Day and Dean isn't missing out on the chance to bang a cheerleader just to console his bratty little brother. He does bring back a heart shaped balloon for him, though. It's not supposed to be cursed.
This whole premise is clever. Love the build-up.

Sam wakes after being soulless for three years to discover that Dean and his relationship with him have undergone some serious changes. Through traveling and hunting with Dean, Sam struggles to put his life back together after events he has only limited memory of. A season six wincest AU
I was kind of resistant to this story initially. It was just so hard to take. But on re-read, I could admire it better. Masterful.

Sam and Dean go a little further. (Sam is 8-ish, Dean is 12-ish.)
I only put this in Kink Corner because of the under-agedness. This age works as an A/B/O fic.
