Incest with young and lustful stepmother

He was a high school student and after his parents divorced, his father married Aika Natsume. Aika's stepmother is a young girl only 5 years older than him. I didn't expect her to be so slutty. He fell under his mother's charm after she propositioned him and he couldn't avoid it. The secret sex in the bathroom and at night is extremely attractive and arousing.
