looking for a title (french movie 80')

[did01]

Hello,

I'm looking for a movie title of a french movie beginning of 80'.
Starring Elisabeth Bur? (Burtaut) and Richard Lemieuvre.
Elisabeth is Richard's wife. He asks her to swallow after blow job but she doesn't want.
At the end of the movie Elisabet swallows cum in front of many others 80' french actors playing non sex in this scene

Thanks for help

Could be Le Droit de cuissage.
