Summoning Sex Demons

I accidentally summoned a sex demon!
When my best friend begged me to use a ouija board with her, I happily obliged. After all, it was Halloween, and I was feeling festive. But I didn’t think we would actually summon anything.
Especially not a seven-foot-tall incubus who shows up at the foot of my bed that night with menacing horns that dwarf my very being.
Our fling was only supposed to last one night. But that one night bound me to him… in more ways than one.
He tells me that I possess a power even he cannot resist, and as our entangled destinies collide, he'll discover he's not the only powerful being lying in my bed.
