Chaoyang has played a good mother in front of her son by hiding her lecherous nature, but... the skin of her disguise has been peeled off in the "Chi-co guessing game". Her son and his friend hide their faces and line up with their dicks out, and make them guess which one is their son's. It was just a prank, but Chaoyang, whose personality suddenly changes when she sees her cock, goes out of control after playing this game.
