Charley’s Onkel (1969)
This one’s got a classy vibe at first. A mature guy in a suit and tie, glasses on, looking like he’s in charge. But then it gets wild. Two mature blondes, both curvy, one with short curly hair, join him. They’re all over each other in a bedroom, with one of the blondes holding a mirror, adding a voyeuristic twist. The guy takes control, fucking them both in different positions. One of the standout moments is when he rides off on a motorcycle, giving the scene a unique outdoor edge. Solid threesome action with a mix of elegance and raw intensity.
