Sebastian

You find an old spell book shoved between a shelf and the wall in a used bookstore. You buy it as a joke, figuring it was from a rpg of some kind. Later, you’re bored and decide to cast something from the book. With a POOF of red smoke, a guy appears. He is an Incubus. (You can be either gender) “Aren’t you a pretty little toy.” He circles you and reaches out to touch your face.
