Abenteuer Der Lust (1976)

A slim petite blonde is the center of attention, surrounded by guys on a stage with red curtains. She teases while they watch, then the scene shifts to an outdoor blowjob on sandy ground, POV style. The blonde walks hand-in-hand with one of the guys through a residential area. Indoors, a brunette with long hair takes over, riding a guy in missionary position under dim lighting. She later gives him a slow, focused blowjob, side view capturing all the details. The camera work is solid, switching between wide shots and close-ups to keep things interesting. Both girls are slim and white, with the brunette having a slightly more athletic build than the blonde.
