Rosalie se découvre (1983)

This one’s all about variety. Two slim white girls with different styles — one brunette with long hair, the other a blonde with a ponytail — take turns with a muscular guy on a bed. The action kicks off slow with the girls sitting together on some stairs, fully clothed, but it doesn’t stay that way. Once they move to the bedroom, it’s all about spreading legs and switching positions. The brunette rides him hard while the blonde watches, then joins in for some shared oral. The camera keeps it tight, so you see every detail of the threesome. It’s straightforward, no fancy setup, just solid fucking with some nice close-ups.
