My parents have a store near the mall. During the summer time, my mom would take me and my brother to the store, and I would spend the whole summer there. My brother was 15 and was old enough to work at the store. I would go to the mall at 9:30am before it opened, and would stay there nearly all day.
I liked to go to the public bathroom, because there was some really exciting graffiti on the wall, and a lot of it. The bathroom was at the end of a long, dark corridor. It had dirty brown doors that you had to push open. When inside it had two urinals and two stalls with dark green paint. It was a texture that was easy to write on. I had not yet mastered the art of masturbation, but I would go there, sit on the toilet, and read the stories people would put on the wall, and slowly stroke my quickly-developing cock. At this time, the only time I would actually bring myself to orgasm was by using a pillow. I had just started cumming white cum.
One time when I was sitting there reading some of the graffiti, I got so into it that I brought a pencil and was adding my own story. Then I looked up and someone was watching me through the edge of the door of the stall. He was probably 15, and made eye contact with me. I didn't know what to think. I saw some hand movement around his crotch, but didn't know what to do.
I looked down at myself, and saw that my dick was fully exposed, sticking straight up in the air. I had developed pretty good for my age, and had a bush of hair around on balls, but not much above my dick yet. My cut cock was about four inches hard. I was slowly stroking it with my left hand, and it was at full attention, though I never did cum in the mall bathroom. I just played with it a little-teased it.
I was pretty nervous because he was so much bigger than me. I thought about opening the stall door to let him in, but then worried about getting caught. Then I thought about walking out and letting him follow me. Finally I decided to just leave quicky and get away from him, because I was a little bit scared.
That's what I did. I left through an emergency exit near the bathroom and ran through the mall parking lot to my parent's store. I made eye contact with him as I left. I remember him turning and following me with his eyes.
I looked for him each time after that when I went to the bathroom, kind of nervously hoping to see him, but I never did. I still wonder what would have happened if we had 'gotten together.'
