Burning for You by Joel Abernathy

Most fallen angels fell for Lucifer.

I fell to save the boy I was created to protect, trading my freedom—and my soul—for his life.
Sterling, the twisted and immortal alchemist who now owns me, is hellbent on using me as the power source to resurrect his murdered lover. My blood provides enough energy to fuel his dark arts, but as the years wane, he turns to more intimate means that are entirely foreign to me—and his touch ignites a fire within me I wasn’t created to discover.
Now that he’s nearly bled me down to the last drop and still hasn’t succeeded in his blasphemous mission, I should despise him more than ever. And I do. But even though I know it means nothing to a straight man who still yearns for his wife’s embrace, the carnal bond our bodies have forged has drawn something far more unforgiveable to the surface.
I’m beginning to fall for him.

Author’s Note: This is a complete standalone MM Romance between a snarky fallen angel and a morally deficient sorcerer that features omegaverse dynamics (no mpreg), bi awakening, smoking hot demons, and extreme enemies-to-lovers dynamics.
