The Intrusion (1975) (1975)
Michael Cattorre. A well dressed man posing as a salesman, bursts in on a housewife, ties her up and rapes her. When her friend shows up for a visit, he rapes her too. He even forces them into some girl on girl sex. This movie is extremely realistic since it takes place only in one home in real time. Housewives should not watch this unless of course they like be roughed up and abused!
