This happened a while ago when I was swimming with a mate. We had got out of the pool and were shampooing and washing ourselves in the shower. I noticed he had a boner. This turned me on and so we left for the cubicles. They had individual cubicles but we thought it would be fun to go in the same one, one of the bigger ones. Once in we pussied around wrapping towels round ourselves. His fell down revealing his small boner with a few whispy pubes. I laughed at this. he said 'oh yeah, bet you ain't got better?!' So I dropped my towel revealing my boner and lots of pubes. 'Wow! was his only word. 'Now I have to wank to get rid of it' I said and began to stroke my boner. He began stroking his. After a while I said 'have you ever been wanked off?' He replied no and so I asked if he'd like to. He eagerly said yes.
So, I walked over to him and sat next to him. I grabbed his boner and began rubbing as fast as I could. He reached over and did the same. I cummed so hard all over ourselves and he dribbled cum out slightly. 'Now I have to shower again' he said and rushed towards the door. Forgetting he was naked he opened the door revealing all to a couple of passing girls who giggled. They went into the next changing room along and we looked over at them and wanked again.
