"Would you like to lose your virginity to beautiful mature woman Rena Fukishi?" Hiro (25 years old), a total virgin, was recruited through an online job posting. When he arrives at the shooting site, a professional male actor appears and starts off by flirting with Rena right in front of him. He heads to the studio, shaken up, and when Hiro takes a shower and returns to his room, Rena shows up to suck the actor's dick, shocking and confusing him even more. Then the two end up on the bed... "What will happen when you show an innocent virgin some naughty play?" This is the theme of this completely prank documentary, where Hiro's behavior and actions are monitored, his reactions are observed, and his virginity is taken.
