The voluptuous wife lives with her husband's father-in-law. He is a very horny man and sexually harasses her every day. One day, the father-in-law calls a masseuse. The wife is also encouraged to receive a massage, and is given some aphrodisiac incense that makes her crotch hot. Before she knows it, she starts to feel it and has sex. As the father-in-law had planned, the wife has intense sex with the father-in-law.
