OKSN-217 "Sex isn't just about being rough, you know" The mother, Ayumi Shinoda, gently teaches her son who is vigorously thrusting

Ayumi lost her husband early and raised her only son, Koji, by herself. She was living a modest and happy life, but there is something strange about Koji who has reached puberty. As she ponders what to do, she notices a dream sperm on her underwear. Ayumi, who decided to teach her correct sexual knowledge for her beloved son, began to teach herself sex as a teaching material. However, she began to show her ecstatic expression on her son's high-speed piston.
