   Summary

   It goes against all Remus Lupin’s better instincts to make an unbreakable vow with a Deatheater. Especially when the Deatheater in question is Regulus Black. But when it comes to Sirius Black, Remus would go to any lengths to keep him safe from himself. Even if it means dancing with the devil.

    

   But first Remus just wants to survive his last year at Hogwarts without any more weird sex dreams about his best friend.
