2069: A Sex Odyssey

How beautiful were the plots of erotic films of the 70s. 2069: A Sex Odyssey, for example, tells the story of five women from the planet Venus, who are sent to the Earth to collect sperm samples. There are no men on Venus, so it’s necessary to refuel this precious liquid from time to time.
Once on Earth, the five extraterrestrials will find that convincing humans to devolve their sperm is not a difficult task.
There are many nude actresses: Alena Penz, Catharina Conti, Eva Gross, Gerti Schneider, Heidrun Hankammer, Hilde Rom, Lydia Mikulski and Nina Frederik. A 5-star movie for nude sequences.
