A father investigates the activities of his two children to find out the reason why his son and his wife have not had children for a long time. Then, he watched and realized that his son was too childish and immature in that matter! The father was very angry and presented a “sex course” for the couple by using their own bodies. Teaching a son how to have sex with his wife is a rare sex movie of an old buffalo grazing on young grass these days. The old man playing the father-in-law is now old and weak, no different from Mr. Tokuda, I hope he will produce more. Good movie for children and grandchildren to watch.
