Whore of the Roses.

A pair of young married couples find that life has just a little more spice when you switch things up every now and then. Kristarrah Knight turns in her best performance in this sexual nailbiter. She plays the lusty young wife of Rick Savage. Their best friends are played by Tianna and Scott Irish, who we meet in a white-hot rollercoaster of a sex scene. The next morning, the guys go off for a day of golf, while their horny ladies spend the morning introducing one another to the joys of girl-girl love. Meanwhile, the guys find that a day on the green isn't exactly what it's cracked up to be when sex Brandy Alexander saunters into their lives. From there, the action really starts to get wild, and by the end of this one, it's flesh upon flesh upon flesh.
