Today, too, the full-time housewife Reiko is busy with chores. Then her only son appears and starts messing with his mother's crotch. Even while talking to her husband on her cell phone, her son continues to mess with her body. When her husband returns home and enters the bathroom, her son takes her there and shoves his dick down her throat through the door. Her son grabs her head in confusion as she senses her husband's presence and is spoken to. After putting her husband to sleep with sleeping pills, her mother is raped again by her son. Her body is defiled with obscene graffiti and fitted with a nose hook, being treated as a flesh slave.
