Sinful Light (Sequel to Heavenly Darkness) (Sebastian x Demon!Reader)

(Read Heavenly Darkness before this, otherwise this will be very confusing!)

Your new life as a demon is undeniably fantastic. Your mate, Sebastian Michaelis, has been teaching you the ropes of being a demon.

You've been all around the world, done everything you had wanted to do, and watched the world change over time. Humans can be rather impressive, but being a demon has been such a better life to you.

After finally picking a house to call home in secluded woods in Utah (off all places), you're ready to settle down with your lover. Not in a family, of course.

Settling down as in ready to find a human to make a contract with. A soul that's satisfied with revenge.

However, you encounter three reapers that are after you and Sebastian.

One, of which, wants revenge of his own.
