Kenji Hyodo, a reproductive physiology lecturer at N University, is a seemingly dull young man who keeps saying naughty words in class. However, its true identity is that of a legendary gigolo who once experienced the ultimate pleasure of pleasure in Europe. "Mr. Flamingo" is the only Japanese to be given the title of the best gigolo! One day, a beautiful girl in a bride's dress, Aya, rushed up to Hyodo and begged him to have sex with her. Aya, the daughter of a zaibatsu, is supposed to marry the person her parents have chosen for her, but before that, she appears to Hyodo in search of her final pleasure. How will Hyodo respond to Aya's earnest appeal...!?
