While cleaning the room, the horny son accidentally finds some old photos of his mother as a slut. He puts the photos away again and hides the camera, and later pretends to find them by chance when his mother is home, and uses the photos to pressure her into having sex. While kissing her son, who inherited the blood of a slut, the mother remembers her days of being a slut, and without knowing that she is being filmed, she straddles her son with her legs spread wide and sways her hips vigorously... I secretly filmed all of this.
