When I was about twelve years old, I still had a tiny figure and girl-like face. Many people always thought that I was a little girl. However, my penis began to grow and could erect by itself.
One night, my mom brought me to a swimming pool for swimming. Since it was a weekday night, very few people used the swimming pool. After the swimming, my mom brought me into the female changing room to take a shower because my mother was a traditional Chinese woman and always thought that I could not take care of myself. In fact, Chinese had the same thinking and did not care so much.
Only my mother and I used the changing room. After I had finished my shower, my mom told me to wait for her. Then my mother took off her swimming suit and became naked in front of me. She did not note my penis grew bigger and bigger and became a horny cock when I saw her big tits, red nipples, black pubic hair, pink pussy and beautiful buttocks. After my mother closed the shower curtain, I heard the sound of water and I began to stroke my penis very gently. I could imagine how strange I was with my tiny figure with a huge horny cock. My right hand moved faster and faster and jerked off. When I enjoyed myself, I did not note that my mom had finished her shower and opened the door at the same time. Oh! my mom saw me ejaculate and a lot of semen was rushing out from my 'penis mouth'.
I was afraid that my mother would scold me because she was a traditional Chinese woman in my eyes. When she saw this exciting scene, she did not say anything but brought me to take a shower. She put the soap on my body and my 'ejaculated penis'. My cock was still very hard and the head was red in colour and was still very sensitive. When my mom stroked my penis by using her hand, Oh! I could not stand and felt so excited that I ejaculated again and again!
She then taught me how to grab her big tits and put my finger deep into her pussy. She was very wet. At last she came to her climax!
After a short rest, my mom warned me not to tell anyone if I wanted to do it with her again!!!
