An adult son can no longer suppress his lust for his fiftysomething mother and her mature, curvy body. One day, he asks her for a favor. She wonders whether he plans to bring a girlfriend home, only for him to confess, “I saw you masturbating... You’re always cheerful and easygoing, but it feels like you’ve been struggling with pent-up desire.” His confession begins a forbidden sexual relationship between mother and adult son.
