The younger brothers visit their older brother's new home. They are warmly welcomed by his wife, Ayane, and soon the husband returns, reuniting the family. However, the brothers begin to notice something strange about their own wife, Erika's, behavior. In truth, the brothers had been remotely controlling a vibrator inside Erika from afar using a remote control—but accidentally turning it off exposes their actions to their older brother. Caught red-handed, the younger brothers instead provoke their brother into joining them in dominating Erika. Meanwhile, Ayane, completely unaware, becomes an unwitting target of their malicious schemes. Watch how this trap unfolds and what comes next.
