I'm looking for the name of a retro porno movie. I saw it on VHS in the mid/late 1990s. Unfortunately, pinpointing a time frame is difficult, because the videotape was of such poor quality that the picture was in black and white and the second half of the movie was unwatchable. My guess is 1970s-1990s (best guess 1980s). Again, unfortunately, pinpointing the country of origin is difficult. The movie was not in English and it had a European feel. My guess is German, but Dutch, Swedish and Danish are possiblities. If anyone will recognise this, it will be because of one of the three scenes I will describe. I remember being told at the time that this was a well-known porno movie. The movie takes place in an all girl school. The heroine is a black-haired, cream-skinned petite. I think her character is called ?Rosmarin.

First scene (which, if I'm not mistaken, is the first scene in the movie): One of the students is dusting, with a feather duster, one of the offices in the school. She hears two people, possibly teachers, having sex in the office next door and spies on them through the keyhole. She then proceeds to masturbate with the handle of the feather duster while standing against the door.

Second scene (which is the most memorable, because it's comic): One of the students is having sex with a guy in the school's grounds, while her girlfriend acts as a lookout. A teacher comes along and the friend tries to distract him by talking to him. At one point the couple are behind a car while the teacher and the friend are on the other side of the car. As the oblivious teacher moves around the car talking to the friend, so do the couple move around the car, while continuing to fuck.

Third scene: (which is not so special): The heroine is sat in the classroom and a male teacher is lecturing from behind his desk. The heroine fantasises about riding the teacher, cowgirl, on the desk. The heroine's fantasy comes to an end either when the bell rings.

There are probably other scenes in between the above and there are definitely others after, but these are the three I remember. Little Girls Blue (1978) was suggested, but that's not it (I repeat, the movie wan not in English). If you know what this is and could let me know, I would be very grateful. Thanks in advance.
