Psychose’X (1978)

Starts with a mature brunette MILF standing in a living room with two guys. Nothing explicit yet, just teasing. Cuts to two slim blondes in their 20s lying naked in bed, partially covered by an orange blanket. The camera gets up close as they fool around together. Next, it shifts to a group scene on a couch — four people this time, two guys and two girls, all white and in their 20s. One of the girls, a brunette, is going down on a guy while the others watch and touch. The lighting is soft and natural, giving it a casual vibe. Things get more explicit later when a brunette gives a blowjob in the front seat of a car. The camera focuses on her technique and facial expressions. Finally, there’s an extreme close-up of a guy and girl having sex in a bedroom, with the focus entirely on their genitals. The variety of settings and acts keeps it interesting, and the performers look like they’re enjoying themselves.
