My Demon Valentine by Aurora Ascher (Book One in the Hell Bent series). The bar may be in hell, but four demon brothers escape that fiery plane to prowl the earth for sexy mortals. In this story, demons AND angels are a bunch of horny bastards, and the sex scenes fill enough pages for a college essay. We ponder the feasibility and merits of sex on hard surfaces (Piano? Countertops? Annie is not on board with the cold - or the blatant gaslighting of the mortal girlfriend.) Pull up your fainting couch and prepare for possession.
