Sam, Dean, Castiel, Gabriel, Michael, Lucifer, Garth, Balthazar, and a few others are all on the same Acapella team; The Treble Makers Sam and Gabriel are an open couple but they want to hook up Dean and Cas (and Lucifer and Michael if they can) So when auditions for solo part come up, Cas and Dean are already competing. Hopefully they win their upcoming competitions! Especially when the Hell Hounds will soon be arriving at their school.

Castiel is just a cute little merman prince that runs into hot human trouble and a pair of beautiful green eyes when his best friend Gabriel convinces him to swim far from home.

Dean discovers that his angel, Castiel, has a very interesting weakness. After triggering this weakness, Castiel must learn to contain it, for Dean's sake, and to keep things from getting awkward. The thing is, though, he can't help it. Warning: Swearing, Boy x Boy, Smut (Imeanwut?), etc.
