A beautiful witch who continues to evolve more beautifully and lasciviously with each passing year. That's Yurie Matsushima, 43 years old. Whether it's good or bad, it's hard for a son to have such a beautiful woman as his mother. He's naturally lustful towards his mother, who is more attractive than any other woman around, and even gives up his virginity to her! Yurie's mother is also curious about her son's penis, which doesn't get weaker no matter how many times he ejaculates. Gradually, he becomes addicted to the forbidden mother-son incest fuck, and can never leave his son and his cock! Recorded in digital mosaic.
