"Is anyone there? I'm in trouble!" Nao, who had just returned from grocery shopping for dinner, heard a heartbreaking scream. Rushing to the kitchen, she 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 was held captive. Nao tried to take responsibility for what her son had done. However... the all-important key was tied to her friend's penis. Nao was speechless, but she made up her mind to try to get the key, but she couldn't take her eyes off the pre-cum.
