Véronique nique nique(1978)

Véronique writes her sexual adventures in her diary. She has come to Paris to work as a maid for a notary, Pierre. She soon catches him with her charms by letting him watch her having intercourse with people like the chauffeur, the gardener's daughter, the butcher's delivery boy, and even them all together. She eventually gets married to Pierre on condition that he lets her free to have sex with whoever she fancies (always watched by him, of course).
