Bourgeoises mais… perverses! (1986)

The plot involves some sort of business rivalry between a rich man with a wife (Jessica Stehl in a spikey blonde wig) and a daughter (Isa Dery, even more punk) and Tina Loren (whose husband is having an affair with Jessica Stehl). Tina Loren teams up with Melissa Bonsardo and Marilyn Jess to put one over on her rival. Various sex scenes ensue.
