  Summary

  After destroying the hotel for the umpteenth time, Alastor makes a promise with Lucifer: in exchange for swapping compliments, learning to coexist, and becoming kind of friends, Lucifer will owe him a favour.

  (Falling in love was not supposed to be a part of that deal.)

  -- in which they fight heaven, each other, and the urge to be together.

  Summary

  Although Alastor and Lucifer have been dating for a few months, they haven’t bothered with taking the next steps. Truthfully, Alastor has never been interested in any of that - until one evening, when he sees Lucifer wearing his red overcoat.

  (Half-naked.)

  And that’s when everything spins wildly out of control.

  -- in which they learn about every form of romantic intimacy, together (aka the 18+ spin-off for Of Saints and Sinners)
