Practically this whole film and its dialog are about the sex life of one couple, Sofi and Paul. One short scene of actual love-making is shot with low lighting. Another, shot in normal lighting, is a flashback scene of how it began, with Sofi on top, topless.
There are several kissing scenes, indoors and outdoors (in a park, in a pool, etc.) In the pool scene and in one in bed, they may or may not be making love, as the action is obscured by blankets, clothing, etc.
Sofi walks into a bedroom fully naked, puts on panties, and flops into bed with Paul.
Paul pulls down Sofi's shorts, massages, spanks, and kisses her sore bare butt.
Paul lies on top in bed and sucks Sofi's nipples, alternating between one and the other. Then they lie there talking for awhile. Then Sofi turns Paul over and does the same to him and shows him it can hurt.
The couple is naked in bed, spooning, with Paul in front, facing the camera. Paul rolls forward, exposing Sofi to the camera. They take turns writing "confessions" on each others' back with their fingers.
On a couch, Paul sits in his skivvies facing the camera with his legs spread, while Sofi lies perpendicular to him with her legs over his lap. Sofi wears an open men's shirt while Paul caresses her breast with the back of his hand.
When Sofi's away, Paul masturbates while we see his mental images of his making love to her (kissing, etc.).
The couple practices a mock break-up scene in form-fitting cotton through which we see outlines of their private parts.
