Fiends With Benefits (Boyfiends Multi-Author)

Desperate to save Standish, his dying lover, Ben summons a demon. When the summoning works, no one is more surprised than Ben himself.

Zazzul is a thousands-of-years-old demon who practices sex magic. He wasn't too impressed about being summoned on his birthday, but once he meets Ben and Standish, he's willing to heal Standish -- as long as Ben agrees to his conditions, of course.

Can Zazzul really heal Standish? And if he does, what will the ramifications be?
