Six friends. Three couples. One sexy adventure.

These three couples have shared good times with each other as friends. But as they celebrate their seven-year anniversaries, they're planning to share some even better times - with strangers.

Vacationing in Miami, Cherisse and Wesley are up for more than sunbathing, when Wesley spies a naughty lady through his telescope and Cherisse focuses her gaze on the lifeguard. Meanwhile, Melanie passes on the hot men at her health club and chooses a private workout with an out-of-towner. When her husband accidentally walks in on them, it's anything goes. And at their rental in Greece, Debra and Gordon discover a Russian couple making love in a private show just for them. For the restless Americans it's quite a come-on - and an irresistible invitation.
