Debbie a blonde college girl, returns home, and is soon seduced by her neighbour Mr Wilson, a notorious swinger, and gives him a blowjob. Afterwards she fantasies about the experince whilst playing with herself. Her mother and step-dad, have sex, ending up with Suzanne being anally fucked doggy-style. The Wilsons come over, and the attractive wife Brenda does a striptease, and soon the two men swap partners, and start having sex. Debbie walks in, and watches the two couples getting into some hotter sex action. Brenda invites Debbie over, and her step-dad is soon fucking her, and then doggy-styles Brenda as she licks Debbie out. Mr Wison and Suzanne had already left by now, and Step-dad goes out to look for them, leaving Debbie to have sex with Brenda but unfortunately this where the end credits roll, and we never see any serious lesbian sex.
