In L’instinct de mort (Public Enemy Number One: Part 1), Florence Thomassin plays a prostitute. We see Florence’s ass as she is lying down in bed and then her breasts as she sits up.
Later in the film, we see a woman riding Roy Dupuis. I didn’t catch her name in the credits, but we see part of her right breast and the top of her ass.
Hopefully part 2 (L’ennemi public n° 1) with Ludivine Sagnier is better.
