The Superior Made of Honey(2008)

Mitsu no Tsumatta Joushi

The handsome hope of the Sales Divison, Ichijyou, discovers that his superior, Supervisor Kirihara, has a body which is too erotic. Since Kirihara hasn’t had sex for the last 10 years, he is agonized by a body reacting to the slightest touch. “This is my first time with such an erotic body... Amazing... It's like the whole body's an erogenous zone.” While Ichijyou is being caught up by the innocent reactions of his supervisor, he is already drowning in that lusty body?!
