She has worked hard to forget her dark past but her mind and body will not allow her to do so completely. She had done a good job of controlling herself until one day her husband brought a friend over to the house and that particular friend happened to be someone that she 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!
