At about the age of 16 I was hanging around with a bunch of guys some school friends, and other mates at a youth club not far from where we all lived. The club was good, we played football, badminton and it had it's own small pool, which hardly anybody used except us lads when we finished the evenings activities. There was about eight of us and sometimes a couple of regular girls would join us at badminton, and then into the pool for a swim afterwards.

One evening we were all pretty relaxed and having fun after badminton, and went to the pool where one of the guys suggested us guys took our swim trunks off and did some skinny dipping. I had never done this before, and wasn't sure how the girls would react. So, instead of getting changed into our trunks, we just took our kit off, and all got in the pool stark naked. The effect on the two girls was amazing, you would have thought they had never seen a cock before. They pretended to be embarrassed but you could see they both enjoyed it, and were having a crafty look at our tackle each time we got out of the pool, or jumped back in.

I noticed one of them girls (I'll call her Pat) kept looking at my cock quite intently. It was nothing out of the ordinary, but I could sense her looking and it was making me slightly stiff.

At the end of the evening, the novelty of being naked in the pool was wearing off, so we decided to get out and get dressed. The novelty hadn't quite worn off for me, as the skinny dipping had made me very very horny. When we got to the male changing rooms I was nearly fully erect, which was noticed by some of the other guys. I knew there was only one thing I could do about it, so I said to them that I was going to have a wank in front of them.

I had overlooked the fact that the girls were in the adjoining room, which had a six inch gap at the top of the walls. I started rubbing my cock, and the other guys all looked on intently. I had never done this in front of anybody before, but was finding it quite a turn on. My cock became really stiff as I pumped away at the shaft, right in the middle of the changing rooms, with all the other guys gathered round me. The head was deeply red and my foreskin got very tight with the stiff erection.

I then noticed that one of the other guys was wanking too, and was letting out slight moans as he neared his climax. This turned me on even more and I was beginning to lose control of my penis. My thoughts turned to the other guy wanking, he wasn't far away from ejaculating, and I remember thinking 'I want to cum before he does'. So, I rubbed my cock with more vigour while the guys watched, and started to breath quite heavily and let out some sighs and moans. I had no idea that the girls could hear this at the time, but if I did I would have cum even quicker.

I pulled my foreskin rapidly over the head, and as I could see the other guy (Jim) about to let fly, I expelled my semen about two foot into the air and onto the ground in front of me. Five or six spurts
later the puddle was complete and my moans were subsiding. Jim then let fly catching me on the thigh as he shot his spunk. I felt the warm trickle of his cum running down the outside of my leg, and this
turned me on again.

The guys were amazed that two of us had wanked off in front of them, but liked what they saw. Later that evening, one of the girls who had been eyeing my cock in the pool, came over and told me that they both heard everything that happened, but wasn't sure who was doing the wanking, and asked if it was me. I blushed and said yes it was and she asked me if I enjoyed wanking off in front of others. I replied that I did, and it turned me on very much. She said that perhaps I could do it in front of her some time as she had never seen a guy ejaculate before. My cock was naturally bulging in my pants again, but I said we would make a date for this to happen.
