It seems you guys a really good knowledge of old european VHS adult movies. I have a nostalgic memories of one which I'm not able to find.
There was a memorable scene with about 7-8 males (all white, I guess), with black ski masks on their heads, standing around. A white actress in the middle was laying on some table. She had dark hair and nails painted red (important), which camera guy focused many times while she masturbated. She had dark hair. All males fucked her one by one. If I recall correctly, the room was blacked out and empty. A little bukkake style, but decent, not ugly at all.
Maybe the key point here is that the movie was filmed like a "sex-school" or something like that. About 30 years old afro black guy with white woman (she had funny hairstyle if I recall correctly) were looking at all sex-scenes and they commented each one. They came to comment, they said some crap and left. Very similiar to "Ancient Secrets of Kama Sutra" from 1997 with Dyanna Lauren.
Probably produced between 1985-1992, German or Italian (not sure).
If you can identify the movie by this scene, I would be very grateful.
