A married couple, who have failed in business, come to the husband’s father for help. The father scolds his son and tells him that he will judge him after seeing him work at his factory. That evening, the father accidentally sees his son and daughter-in-law having sex and finds out that she is not satisfied. The next day, when no one is around, the woman masturbates to soothe her hot body and is caught by her father-in-law, who just happened to come home. The father-in-law, who is still in good shape, satisfies his daughter-in-law’s sexual desire instead of his son, who can’t give her that.
