My name is Xiaojun, I am ten years old, and I am in the fifth grade of elementary school in J City. My father is a biological scientist, but I often have to do some scientific research and cannot be at home. I have been there for more than half a year, so I basically live with my mother. My mother is a teacher. Coincidentally, she teaches in our school, but she just doesn't teach me this class. I just want to introduce my mother. My mother is named Zhang Ru. She is very beautiful and has a good figure. However, in school, she wears very conservative clothes, not slim-fitting. Generally speaking, only I can see her good figure. But I am still young after all. Although I have learned to masturbate, I have no desire for my mother. Until something happened later, it made my desire a world of difference...
