A married woman in her third year of marriage lives with her husband's father. Her busy husband is often away on business trips, and with no marital relations, the frustrated wife masturbates. Her father-in-law smirks as he peeps at her. One day, a delivery man who is her lover comes over and they have sex, but her father-in-law is watching again. Using the masturbation and cheating as leverage, the father-in-law demands the voluptuous daughter-in-law's body. Threatened that he'll tell her son, she can't refuse and spreads her legs. Furthermore, she is night-raped and made to cum repeatedly by her despised father-in-law.
