When I was 15 I had a paper round in the morning & evening. A girl from a rival shop also delivered to my area and I often caught her looking at me.
On this day the papers were delayed and I was reading through the magazines on sale. There was no way I could look at the porn, but I did find a Christian leaflet which was aimed at kids. This went into great detail about masturbation and why it was so wrong, stating that release could only be had between 2 married people. This fed into my feelings about myself-I would masturbate but feel dreadfully guilty and swear never to do it again, only to crack when the pressure got too much.
The leaflet aroused me (the opposite to the desired effect from the authors) and I had an erection in the shop. The papers arrived and I grabbed my delivery (plus one to sell to my parents) and put the sack over my shoulder. This was resting over my cock and the rubbing sensation was very pleasant. I jumped onto my bike and started to pedal toward my round. The rubbing of the bag grew more intense and I did not know what to do. I arrived at my fisrt drop and felt so close, but I also felt terribly guilty about pleasuring myself. It felt like I could not turn back, and just as I resigned myself to the inevitable, the girl that I fancied came around the corner. I pushed myself against the bag and as I watched her looking at me my knees buckled and a stunning orgasm overtook me in the middle of the street. I balanced myself and felt pulse after pulse of hot come filling my pants. I felt both dirty and relieved, and had to finish my round with the feeling of stcky come against my balls. I got home, cleaned myself up, but was so turned on I immediately had to pump my cock again, coming into the bathroom basin with thoughts of the lovely Karen in my head. I never got to go out with Karen, but I would often watch her from my window as she pedalled past, pumping myself to a climax in the comfort of my bedroom.
