Her Son's Girlfriend

Lovely and innocent young Cheryl would never have guessed her boyfriend's sexy mother and father were involved in a kinky sadomasochistic relationship. Not until she is accidentally trapped naked beneath their bed and forced to watch. But when she is caught she finds it impossible to say no to the stern older woman, impossible to deny her the right to punish her as she chooses, to humiliate her, or even to train her in the proper sexual behavior she expects of her son's girlfriend.
And when her boyfriend's father joins in the bewildered girl is unable to restrain her own dark sexual hunger, allowing herself to be trained into submission and bondage. But is it the perfect girlfriend they are training for their son, or the perfect slave?
