In the suburbs, swinging isn't just for the playground. Kaysee Smart thinks she is content with her life of driving the carpool, enjoying play dates and trying that exciting new recipe for the next potluck. But when her conservative husband, Justin, casually suggests inviting someone else into their sex life, a new version of Kaysee emerges. Increasingly intrigued by the idea of a threesome or foursome, Kaysee questions her own identity, wondering if she truly is the "good girl" she has always proclaimed herself to be. Searching Internet sites for sex partners and Googling "how to be a swinger" plunge the couple into a taboo world that most people imagine but few actually visit. As Kaysee and Justin begin to live out this fantasy, they experience a sexual re-start they didn't know was still possible. They also find that experimenting outside the norm can have unanticipated consequences. Consensual Infidelity is the true story of an all-American, suburban couple's experiment with swinging and how the experience redefined their beliefs about marriage, love, sex, and fidelity.
