The married woman, now in her third year of marriage, lives with her husband's father. Her busy husband is often away on business trips, leaving her unsatisfied and resorting to masturbation. However, her father-in-law catches her in the act and finds it amusing. One day, her secret lover, a delivery man, arrives and they have sex, but once again, the father-in-law witnesses the encounter. He then uses this knowledge to demand sex from his daughter-in-law, threatening to expose her infidelity to her husband. Unable to refuse, she gives in and opens her legs. Later, she's taken advantage of and repeatedly raped by her despised father-in-law.
