Couples en chaleur (Jacques Parry as Sam Corey as Jean Luret, Movies) 
Cast: • Brigitte Lahaie • Catherine Castel • Catherine Ferré • Elisabeth Buré • Gwenda Farnel as Karolina • Maryline Guillaume • Cyril Val • Charlie Schreiner • Gilbert Servien • Pierre Taylou • Norbert Ciret
3 couples are closed friends, they live in a beautiful house owed by the mother of one of them, the mother has an obsession for flowers. The 3 guys have a band and play as amateurs. They have good and regular sex all together in the house and in the garden. One day they are offered to record in Paris, and guess what, also in Paris they do have good sex.
Young Brigitte Lahaie appears in the last scenes, first as a seller in a guitar shop and, I have no idea why, she follows the guys to the recording studio and participates to the final orgy. It looks like the cast was partly changed for the scenes in “Paris”.
