A son and his wife end up living with their father-in-law, who lives alone. Not knowing that her father-in-law is a big fan of breasts, Leona, a full-time housewife, spends her days defenseless. Her voluptuous breasts unconsciously stimulate her father-in-law's lower body, and seeing him trying to hold back, Leona plots to seduce him and get him to buy her some designer goods. Unable to withstand Leona's provocative behavior, the father-in-law makes a mistake. Once he lets his guard down, the father-in-law forgets that she is his son's wife and relentlessly indulges in his carnal desires.
