When Anne (Léa Drucker) has sex with her 17-year-old stepson, she closes and sometimes covers her eyes. It’s a pose that brings to mind what people say about the tradition of draping a napkin over your head before eating ortolan, that the idea is to prevent God from witnessing what you’re about to do. Théo (Samuel Kircher) is as fine-boned as any songbird — “You’re so slim!” Anne gasps in what sounds almost like pain during one of their encounters, as she runs her hands up his rangy torso — and just as forbidden.
