A Touch of Evil (The Exxxorcist Files Book 1)

Dick Perry—the name is not meant to reflect any person, living or dead who may or may not have been a governor—is an exorcist. Peter is a young man possessed by a demon, a demon with a forked tongue that it knows how to use, slurp.

With plenty of holy oil making things slick, Dick must thrust deep into Peter until the struggle with the demon comes to an explosive finish. Then they do it again and again until they can’t do it anymore.
