Curvy Jennifer Larkin celebrates her fifth wedding anniversary by watching her husband dance with thin, attractive women. Her sister urges her to get out there, but since gaining the weight she feels unattractive. Worried that her curvier body will disgust her husband, she makes excuses every time he wants to exercise his husbandly rights.

When hot, young Dr. Davies examines her she fantasizes about being taken by him and her husband.
