Collin and Larissa, a young married couple, agree to move forward to fulfill their shared, forbidden fantasy; to invite a woman into their bed. With great trepidation they post on a swinger's web site. This would be their first experience, so there was no telling what kind of trouble they might be getting into. When they meet a stunning woman named Phoebe, they can't believe their luck. What follows is an adventure in life none of them saw coming.
