Takao, the manager of a long-established inn, is approached by the landlady one day with a request: to train the inn's heir, Chiaki. Once an angelic little boy, Chiaki has grown into a bit of a playboy. The story of their love starts unexpectedly on his first day of training. That evening, when Chiaki is told he can't go out at night to mess around, he responds with an unusual request: "In exchange, if I try my best, I want to get a treat for it." When Takao agrees, he suddenly finds Chiaki inching closer... with a lustful expression. Shaking as Chiaki's hot tongue explores his mouth, he feels engulfed with a newly discovered pleasure.
