I just finished reading killabeez's lovely stories And The Devil Makes Three
and Siren Song
. SPOILERS FOLLOW!! The fact that Dean and Sam and the OFC end up together and the scene near the end where Sam and OFC have unprotected sex (Dean already has kids with her) made me itch for a fic where Dean and Sam have kids with the same woman. They can end up in relationship, ideally, or if not I'll even take whatever, surrogate or weird demon hoodoo, however it happens. Also, it doesn't have to be an OFC, can be Jess/whoever from the show.
If that doesn't exist, I'll also take more Dean/Sam/SomeGirl threesomes. Longer fics not required but also a plus. No mary sue type stuff, please.
.... I guess I'd also take creative interpretations vaguely related to my request e.g. where one of the boys is genderswapped and has kids with Dean and OMC; or they're both girls and have kids with the same guy? Idk....
