Warning: Warning for non-consensual sex sex at the beginning that eventually turns into consensual sex as Dean is cleansed.
Anonymous Prompt: Crack/MHC. The Mark of Cain can be removed with enough sex from an angel. Sam restrains Dean while Cas fucks him for an impressive length of time until the Mark of Cain is gone. Non/dub-con at the beginning, con at the end. Wincestiel by the end of it. No established Destiel, but previous UST and/or previous wincest-on-the-rocks. Both care about Dean. Sam might not have sufficiently holy jizz, but he still is heavily involved with other stuff. Bonus if they decide to keep up the sexual arrangement after Dean’s back to normal, double bonus if Dean wants to spend a lot of time making it up to them. Triple bonus for a little bit of submissive!apologetic!Dean and power-play D/s from Sam and Cas towards Dean, treating Dean as being on probation of sorts until he can prove himself responsible (after all, he did get himself into that whole Mark of Cain mess).
The thing is, other than the fact it’s responsible for giving him orgasms, he hates his dick, he doesn’t like his tiny chest, and he figures there was a mistake somewhere along the way causing him to be born a boy. Dean has shared his secret with a few women over the years, and they’ve been surprisingly okay with it, but no one else knows, including Sam.
Dean gives up telling anyone about it or having any hope at all after Hell, after being rebuilt by an angel, because if even God has decided he belongs in a male body, then Dean must’ve been wrong all along. Until Charlie comes along and flips his world upside down.
Set in Season 9, but (spoilers) this fic poofs away Sam’s possession issues, disregards the end of Slumber Party 9×04, gives Castiel his grace back, and even though he’s adorable, poofs Kevin away.
