Stepsisters Rachel and Stacie had a history of sleepwalking. At night they would rise from their beds and wander round the house in nothing but their skimpy bed clothes. Rachel's stepson Kenny often found them lying in some strange spot the next morning - confused and unaware of how they had gotten there. The stepsisters grew increasingly concerned about their condition and went to see a specialist. Kenny was secretly excited by this fact. Although his stepmother and his aunt thought him a sweet and trustworthy young man, he was really very devious and immoral - with a strong, forbidden lust for both women.
