   Summary

   Castiel Novak and Samantha Winchester, fast friends, meet at a social group for autistic teens. They both happen to have protective, obsessive siblings, but it's fine!! Sam loves her big brother and their relationship is SUPER normal!! And Cas loves his twin sister and the crazy-ass sex they have!!

   In which Dean accidentally grooms his baby sister right into some incest, Sammy would follow her big brother anywhere, Jimmie fucks her twin and likes the way he hits, and Castiel is really fucking tired of the lot of them.
