Ms. Ryo Otsuki, a married woman, married a small restaurant owner and then lived with the most difficult family in the area. When her husband went on a business trip, she was home alone because she was so frustrated with a conservative and impotent husband, so she decided to have an affair with her neighbor. Flirting was always what she was best at, so she couldn't help but seduce this neighbor. She and he had sex many times, not only today but also many days after that. He ejaculated into her pussy countless times.... One day, like usual, she went to his house to fuck him, but she was surprised because he invited her friends. She refused but couldn't because the door was locked. And then she still agreed because she had never had sex before, which made her curious about it.
