Since last month, Sachiko has been living in mental turmoil after being raped by her son. Today, while she was cooking, she found him standing behind her without noticing. His eyes gleamed menacingly as he seemed ready to pounce on his mother at any moment. The son wishes to have sex with his mother in front of his father but, naturally, the mother refuses. One day, following her son's orders, Sachiko makes her husband drink sleeping pills. Reluctantly complying with her son's commands, Sachiko is raped by him in front of her unconscious husband. As he puts his hand into her underwear and thrusts his penis inside her vagina, she loses all reason and lifts her hips to take his penis deep inside her. Despite feeling regret, after her son finishes, she herself begs for his penis again, reaching orgasm multiple times with a cock that is stronger, harder, and bigger than her husband's.
