In the second scene, a married couple is seen in bed. They turn off the light and she tries to incite her husband to have sex. They are covered by sheets, but in between her nipple is revealed. She uses a sex toy to provoke her husband. The scene ends with the little son interrupting them because he has nightmares.
In the middle of the movie, the couple go back to sleep. She wants to have sex with him again. This time the scene is shorter, and he is again interrupted by the young son. No nudity or sex toy is shown. But the image the child sees is her on hers, as if they had started.
Hard jokes are made about the spontaneous nudity of a child over 6-7 years old.
