Ryoko Kurosawa is 50 years old and a full-time housewife. I live happily with my husband and son. However, the truth is that I had a relationship with my son once when he was still a student. Recently, however, my son has started relying on me again. I know that we shouldn't do that kind of thing between a parent and child, but my body is craving my son... This is a secret that I can't tell my husband.
