Schulmädchen-Report 8. Teil - Was Eltern nie erfahren dürfen

In the 1970s a company in Germany began making movies about German Schoolgirls. The earlier movies had staged and real Man-In-The-Street interviews and various skits supposedly about German High School Girls, but the plots and pseudo interviews were always secondary to the main goals of these movies, which was to show Full Frontal Female Nudity, and simulated sex. By this 8th entry in the series the interviews have been dropped. This movie is about a bunch of schoolgirls riding a bus and talking about sex. Each talk turns into a skit about whatever they were talking about, and then the narrator of the skit is shown naked. For example, one skit is about a Schoolgirl who visits her Country Cousin, and they go skinny-dipping. A guy who has been fishing next to the "Angeln verboten" sign steals their clothes. After they're done skinny-dipping they find their clothes have been stolen, then they see him standing there and they run away. In slow motion.

Eventually the bus arrives at a hostel, and all the girls take a group shower with over a minute of about 10 naked women taking showers with full frontal nudity.

This movie excellently accomplishes its goal of showing as much attractive female flesh as possible.

AFAICT no Schoolgirls were used in the making of this movie.
