"Is anyone there! I'm in trouble!" After returning from grocery shopping for dinner, Nao heard a desperate cry. She rushed to the kitchen and found her son's friend handcuffed and unable to move, desperately calling for help. Apparently, he had gotten into a fight with her son and been restrained. Nao decided to take responsibility for what her son had done. However...the crucial key was tied to her friend's penis. Nao was stunned but resolved to retrieve the key, but she couldn't take her eyes off the semen.
