John Lindsay short included in Your Scene collection Mary Millington and Friends
This begins with a curly haired brunette (Kelly Francis) going down on a bloke in a car. This is intercut with a blonde (XNK0473, obvious wig so may not be blonde) having sex with a man on a bed. The couple pick up a copy of Le Figaro from a garage door and drive off to the blonde's place where the bloke enters the room and kills the man having sex with the blonde. He heaves him onto the floor and the blonde faints. He is interfering with her when the brunette walks in. She tells him off, but they end up having sex on the same bed.
