When Mayuko suddenly woke up, her body was tightly bound with hemp ropes, completely immobilizing her. Sensing something was wrong, she called out to her son Satoshi for help, but instead of assisting her, his eyes bloodshot, he began groping her all over. She realized she had been tied up while asleep. Though she knew Satoshi had unusual sexual tendencies, she never imagined he would target his own mother. Mayuko desperately tried to escape, but the ropes dug deeper into her flesh, robbing her of every last bit of freedom. Resistance was futile.
