Movie scene where actress show vagin to male actor

I’ve found, some years ago, a video on Dailymotion where a french actress, leaning on the wall, put down her panties to show her vagin to a male actress. Then she says “Voilà, that’s all” o something similar in french and then cover her privates…
The name of the video contained the actress’ name but now I don’t find that video any more for years… Some ideas who she could be and which film was?
