Die Schulmädchen vom Treffpunkt Zoo (1979) is a German sexploitation flick set in and around a high school and a train station. Though there are subtexts of drug abuse and prostitution, the main point, and a marvelous one it is, is to show as many naked German teenagers as possible. There’s lots of great nudity, but look for the locker-room scene with Martina Engel and Karin König showing off all three glorious B’s at once.
