My first experince at school was with a girl called Linda. We had done the usual teenage stuff, I had seen her muff, and she saw my cock. One day she told me to meet her in a secluded place because she had 'borrowed' a copy of Razzle from her brother. She turned up and said the deal was that she wanted to see me wank, and the only condition was that I did not cum on the jazz mag. Half way through and I heard titters, and her mates were all standing behind me, and the language started. Coarse Essex girls, fist pump 'you fuckin wanker', 'spunk monkey' etc. I was so ashamed, blew half a load, ran off and hated the wanker nickname.
I was shy and humiliated, and it was only years later that I found out that Linda and her mates did that to a number of boys. They seemed to pick the ones that were not worldly wise, from strict homes etc. Basically, the ones that would give them the best reaction, and would feel the most shame.
However, now, looking back, it was so hot and that is behind my dirty fantasies. So, you see, your mate being nice is not the turn on, a group of girls giving me the wanker fist pump and jeering is what gets me hard and gets me off.
