My name is Xiaodong. I am a 16-year-old high school student. Although I am very young, the thing below me is quite large. For a long time, I have been the envy of boys in our class.The main reason is that I was different from other boys when I was very young. I had a morning erection at the age of six or seven, and my erection was as thick as a normal young man's cock. At first, my mother thought I had something, and thought it was a swollen prostate, so she took me to the hospital for treatment. Even the middle-aged doctor who treated me couldn't help but laugh and said that my mother gave birth to a big cock son.According to normal development, my cock can grow a lot. It is estimated that my cock can grow to 20 cm, which is one quarter higher than the average 15 cm for Asian men. At that time, I didn’t feel anything and didn’t care. But as I got older, I found that my male secondary sexual characteristics could become my weapon to show off, and at the same time, it has also become the most powerful tool for me to conquer my teacher.
