This is a romantic dramedy about two people who have a passionate affair for a few days a year, something they have done for 20 years – while they live completely separate lives with other spouses. It sounds a lot like Same Time, Next Year (1978).
Emmanuelle has several sex scenes, a bath and a shower, but there is no topless nudity. I knew that Chriqui’s scenes would be teases, and that I was kind of wasting my time with this flick, but she is my kryptonite! She is 50 years old, but she is playing a character about 35, and you would never question it for a second.
There is one scene when she appears to be topless, albeit far from the camera, but when I blew it up 4x (below), it was obvious that she was wearing a flesh-colored covering over her breasts.

I covered her bare-butt scene and her nude history here.

Are the nude/topless pics of her on a google image search all AI or fake? Nothing from movies, right?
The bare butt scene in this movie is about it for films, but she did pose topless for Randall Slavin’s “Achromatic” exhibit that opened at the KM Fine Arts Studio in L.A. on April 13, 2016.
That’s this image
She has a nude scene from her younger years. Her nude debut, as far as I’m aware, was in the Showtime series Borgia. Her butt was visible through a see through curtain.
That was covered in the link at the bottom of the post. I suppose the article in Allure, a year before The Borgias, was still her best nudity, unless you count that Slavin picture. What a shame.
