I knew my son was acting strange lately. He licks my body and uses my underwear to masturbate. However, I didn't worry about it that much because I thought it was due to the stress of university entrance exams. At that time, an incident occurred. When I was video chatting with her husband who was on a business trip, my son suddenly touched my body. Then, in a situation where she couldn't speak in front of her husband, she had an affair with her biological son.
