My mom and I demonstrate sex

This is what happened in the third grade of my health school. In June that year, as soon as the graduation examination was over, I had nothing to do in the school, so I went to my first grade teacher, Mr. Chen. Miss Chen has always taken care of me, and I am very grateful to her. I sat in Mr. Chen’s office for a while and chatted about her recent human anatomy class. She said that all the classes she took were girls and they were very stupid. She asked me if I could help teach my younger sister. Of course, I said no problem, because Mr. Chen is one of my favorite teachers and the first in our school One of the beautiful teachers. Such a beautiful teacher asked me to help, of course, I am duty bound.
