A few days after moving, Shinichi couldn't help but be curious about Maki, a seductive married woman he met at the garbage dump every morning. One day, he went to a cooking class recommended by a colleague at work, and to his Maki, Maki was the instructor. He was surprised, but she was a secret sadist who played with him everywhere, and continued to control his ejaculation, making him experience the ultimate orgasm and endurance. A week later, Shinichi began to realize his own hidden desires as Maki trained him.
