Incredible classic scene with Fabienne Ernst and Virginie Chevrier

Lovely Olinka and her girlfriend Kathy Kay (a tomboy Kristy McNicol type, with nice tan) go for a vacation in the mountains, paid for by Kathy’s married boyfriend Jean Oury, who is also seeing the Alps with his wife Dominique St Clair and daughter Sophie Ziller (if she’s Alsatian, she may be the 12-stringer’s 42nd cousin). St Clair is getting some action on the side, and Sophie runs into drifter Gabriel Pontello (not played very menacingly, despite the obvious opportunity in the casting). Everybody switches, swaps, and has a good time.
