More than i bargained for...

When i was about 16, i would ride my bike to a bypassed old road where couples would go. There was always a great number of used porn mags and occasionaly knickers that some girl had used to wipe her cum filled cunt after a late night fuck. I was in this wooded layby area with my cock out wanking into a pair of knickers when an older guy of around 65 showed himself. He had been there some time wanking himself and had seen me there before. He asked me if i had sucked a penis before. Which i had. His one was dark red, very veiny and a big foreskin. He said not to be scared and that he wouldnt tell any one. He motioned for me to kneel infront of him and sucked him till he spurted a thick load in my mouth. I nearly choked. He zipped up an left leaving me feeling dirty and used....but i wanted more
