I was only thirteen when i discovered the pleasures of sex. I used to visit my local running track which was close to my home, and on numerious ocassions i would go for a walk in the forest close by.
My favorite passtime was to stand and watch the people walking past. Because of the trees and bushes nobody saw me as i would stand and wank off, spilling my cum over the ground.
One day i was standing wanking my self off as i watched a mother and her two young girls playing close by. My cock was really hard and throbbing and i was close to cumming when i heard a noise behind me. I turned round, cock in hand, to see a man standing about ten feet behind me looking at my cock.
I didnt know what to do, run, hide, or just stand there. So i did nothing. He looked at me and nodded. At this stage my cock had gone down, so i started to stroke it again while i looked at the man standing in front of me.
