Insatiable (2005)

She is a happy housewife, but she once lived on the edge. It was a dark chapter in her life. She has worked hard to forget her dark past, though her mind and body will not allow her to do so completely. She had done a good job of controlling herself - until one day when her husband brought a friend over to the house, and that particular friend happend to be someone that she had had a fling with during her wilder, darker days. The lust that was caged for so long has now broken free... There is nothing holding her back now!
