Beyond Soho (1989)

A couple is having sex on a bed. He's on top of her, bottomless in a shirt with his butt visible. A man bursts in, pulls the man off of the woman and pushes him out of the room. The woman, nude (breasts showing) jumps up and quickly pulls on a dress. The intruder wraps a cord around her neck choking her as a second man enters. The intruder pulls the top of her dress down and plays with her breast while the second man asks her questions.
