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. Her father-in-law, however, finds pleasure in watching her pleasure. One day, her secret lover, a delivery man, arrives and they engage in sex, but the father-in-law catches them in the act yet again. 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 gangbanged and repeatedly raped by her hated father-in-law.
