Us Against Them

Fluff/Smut/Adventure. Dean and Sam are hunted down by demons looking for Cas. When they retreat to the Bunker, Cas and Dean are free to explore their feelings for each other. Rated M for smut (obviously) and language. Destiel, because apparently that's all I know how to write. No angsty ending, NO CHARACTER DEATH. Our fandom could use some happiness. [COMPLETE] [Sequel up now too!]
