Cathy is a hot wife but she doesn't know it yet. 

Cathy, 26, tall and curvy, had sex with two men by the time she was 21. One she'd known just long enough to get pregnant, and Dan who is the love of her life. They'd spent Cathy's last year in college flashing and having sex in public places just for fun. When Cathy's mother died, Dan married her, moved her daughter in with them, and they settled down, Cathy teaching school and raising Molly, and Dan as a program manager for a start up. 

But that spark of adventure still burned inside them. On a rare date night at the beginning of summer, a dare to flash an older gentleman gets Cathy groped and her panties stolen. Instead of being upset, both Cathy and Dan are excited. This new idea, seeing Cathy sexy with other men, became real when Dan showed Cathy an ad for a nude modelling gig. The catch? There would be male nude models and the theme would be erotic love. 

Cathy attends the audition, which consists of her, the male model, and the photographer director who explains they are making a movie about a young housewife who is modeling for an erotic couples boudoir photography website, and whose modeling sessions "get out of hand". Being cast to type, Cathy struggles to maintain her virtue while pretending to be with her lover for the camera. 

The three days of shooting, the three scenes of the movie, bring her to edge of infidelity and then over the edge. What Cathy discovers about herself scares her, but her bond with Dan is strong enough to allow them to move on to a new stage of their relationship.
