Classe mista (1976)

This one’s got a bunch of random scenes. Starts with a white guy in his 30s with short white hair and a white woman with red hair, both just chillin’ in what looks like an office. Then cuts to some outdoor shots, a classroom scene with 3 people, and a girl sitting in a car. The sex scenes are pretty straightforward – a brunette girl gets fucked doggy style by a guy with dark hair. The redhead from the beginning also gets laid, jerking a guy off in a classroom. Nothing too crazy, just some decent fuck action.
