Old french dom/sub relationship movie

Hi guys. So like 5 years ago I watched on popcorn an old french, maybe 70s, 80s movie about a guy that comes to Paris I think, he meets an older woman and a young nice looking woman. The movie is about dominance and quite kinky relation between them, where they both dominate younger woman,and in the end they end up together. I remember scene in a park with rose and a scene with buying a book from a street vendor. Also a scene with a saleswoman getting into the relationship. Any clues? Thanx!

The Mother and the Whore?

No, not the one. The name is short, one word, as I recall.
I watched this one and it’s great, though.
Thank you for the reply!
