Ethan Winter has always wanted to be an FBI Agent. Until he's accepted he's stuck modeling underwear and working for a private investigator. But when a trip to Las Vegas for a security conference brings him into contact with the magnificently dominant Maxmillian Poole, Ethan is faced with a dilemma: pursue his childhood dream or become the partner of a man any submissive would crawl for.
