At first, I thought it was the stress of university entrance exams. My son, Osamu, has been watching me lick me and masturbating with my underwear. But I never thought it would turn out like this. One day, while my husband was on a business trip and was away from home, my son violently wanted my body. At that time, my husband came home earlier than planned, and I had a nasty relationship with my real son in a situation where I couldn’t even speak.
