The Orgy Machine (1972) (Better Quality)

This one starts with a close-up of a white girl in her 20s, slim with a smooth pubic area, examining herself. Then, two guys join in, all Caucasians, and they start intimate touching, hands on genital areas. The scene shifts to a dim bedroom with a bed, where three of them engage in group intimacy. The camera captures a mix of close-ups and wide shots, showing their interactions. The white teens are all slim, and their chemistry is evident in how they move together. One notable detail is the clear view of their interactions in a natural indoor setting.
