In his forties, Kikura holds the position of dorm caretaker. One day, he's called upon by a student who complains about the notorious womanizer, Seji. Kikura quickly heads over to Seji's room to investigate, only to catch him in the middle of intimate activities with another man. Seji, perturbed by the interruption, forces himself upon Kikura - who has been deprived of pleasure for some time - initiating a fiery and provocative cohabitation between the sexually-liberated student and the unwittingly adventurous caretaker.
