I have done some searching but have drawn a blank. Christine Szenetra is the woman who starts playing with the guy after he comes in and sits down. Sandra Nova AKA Uschi Karnat is one of the 2 women playing with each other when Inge and Mother come into the sauna
There is a version floating around (not on here unfortunately) called Die Familie Bergmann that has English subtitles. I understand this was one of a series of short movies - maybe 3 or 4 on one video cassette
Ja! Nicht jur das ich die Szenen mit der Tochter am geilsten fand, ich hätte auch gern gesehen, wie die Mutter vor den Augen der Tochter gefickt wird … So wie es bei mir war und es machte mich mega geil, meine Mitter dabei zu sehen.
