First time watching

When I was younger we would go camping in the summer with our friends and neighbours. There were usually between 25 and 30 of us and we always had a really good time. One time when I was in my teens our neighbours brought along their friend a guy called Jeff. He was mid to late 30's and he seemed to be a really nice funny guy. During the first week every body was having a good time and I spoke to Jeff on many occasions and everything was great. On the first weekend I was at the shower block and I bumped into Jeff. We started chatting about nothing in particular when he asked me if I had a girlfriend. I told him that I didn't and he said not to worry as we can always enjoy ourselves without a girlfriend. I said yes I suppose so. He then said we can always have a wank can't we. Slightly taken aback by this I said yes we can. He asked me if I had started wanking yet which kind of embarrassed me as I had only just discovered the pleasure of masturbation. He said it was nothing to be embarrassed about as all guys did it. He told me that he regularly enjoyed wanking naked and then asked if I would like to watch him? Having only ever seen a naked man in a porno mag before and having just discovered the pleasure of masturbation myself the thought of watching him seemed rather exciting and so I said yes ok. We went into the block and into one of the family shower rooms. Jeff told me to lock the door which I did. He pulled his shorts and boxers down and stepped out of them. He then took his t-shirt off and stood in front of me completely naked showing me his smooth semi erect cock. After a moment he asked me if I liked his cock and I said yes. He smiled and started gently touching himself. I could see him getting harder and a couple of minutes later he was fully erect and very hard. He began slowly wanking and as I watched his hand working up and down his shaft I could feel the excitement in me building. I was absolutely fascinated watching him wanking and the more I looked at his big stiff cock the more excited I became. After 5 or 6 minutes Jeff turned to his right giving me a side view of his cock as he wanked. He asked me if I could see see all of his cock and I told him that I could see it and his balls. Looking at him pleasuring himself really was fantastic and when he asked me what I thought of his cock I told him that I thought it was lovely and that it was very big. The excitement in me was huge and so after a few minutes when he said would you like to feel how hard it is, I straight away said yes. I put my hand round his cock and gently squeezed it. It was big, warm, very hard and felt lovely in my hand. I slowly ran my fingers over his cock and balls and I felt so excited as I did. After letting me touch his cock for a minute or two he said why don't you have a go at wanking me off and I said ok. I began slowly wanking his cock for him and the feeling of his hard cock in my hand as I worked it for him felt wonderful. I asked him if I was doing it right and he told me I was doing it perfectly and to not go too fast. Jeff let me wank his cock for about 10 minutes then took over. He stood facing me working his hard cock and asked if I wanted to see him cum. I told him I did very much and he said ok and began wanking faster. A couple of minutes later he told me to step closer and look at the end of his cock and as I did he let out a loud moan of pleasure and I saw his cum shoot out. Jeff is one of those guys whose cum shoots out about 12 inches and I was so excited as I watched load after load shoot from his cock and with every stroke he produced more cum. When he was finally finished he stood there with his hands on his hips showing me his cock which was now covered in his cum. As I looked at his cock I asked if I could touch it and he said help yourself. I held his lovely semi erect cock in my hand which felt wonderful then I ran my fingers over the end of his cock and wiped his cum off. It was warm and felt really nice as I rubbed my fingers together. Jeff got dressed and we went back to the others. A few days later we all went home and I never saw Jeff again but that wonderful experience has stayed with me to this day.
