Three young, attractive, prosperous married couples who are old friends spend a weekend together in a posh Santa Barbara-style house. One extra single girl, recently broken up with her husband, and also in the clique, adds extra interest because all the guy friends have long lusted after her.
Interestingly, only one wife cheated in this movie (the short-haired blonde) and it took a while to get there. She fucked one of the other wives' husbands in the kitchen at 1:10:30. Their flirty dialog and interaction just before they fucked were quite sexy. Their lovemaking was interspersed with the lovemaking of her husband and the divorcee.
