I had gym fourth hour, and then I always stayed after to swim a couple of laps in the pool. I'm not really buff, but I stay in shape. I was getting out of the pool, and had a bit of a boner going on one day, and since no one was around, I didn't try to cover it up. I walked into the locker room, and heard a shower going. Great! I wrapped my towel around my waist, and walked carefully down the middle of the locker room, to where the showers were. When I walked around the corner, I saw Jackson, he's on the football team, and he must've just started the shower, cause he was standing away from the water, holding out his hand under the stream, and he had a towel on too.
I said 'Hey Jackson', and he turned and said 'What's up man?' I started the shower closer to me, and took off my towel, turning away from Jackson, so he couldn't see my boner. I took off my swimsuit too, and got under the hot water. It felt really good, and I stayed facing away from Jackson. He asked me about the homework for American History, and I turned to look over my shoulder to talk to him, and let him know what chapters we had to read for tomorrow. He had his hand over his dick, and said 'Thanks'.
I turned back and was trying to stop my boner. It didn't help when I started to soap myself up, and got down to my boner. I keep myself trimmed, so when I washed around myself, the bristly hairs tickled my dickshaft, and I got even harder. I was so humiliated. But then Jackson said 'Hey man, don't even try to hide it, we're fucked'. He laughed when I turned around. He moved his hand, and his boner popped up. I turned all the way and let him see mine too. We both laughed and it was really awkward.
I kept soaping. We were trying to talk normal, like nothing was wrong, and he said he was going to take care of his, if I wanted to join. I said I wasn't sure, and he started to jack off anyway. He was whistling casually and I laughed and said 'OK, I'll join you'. So we were both showering, and jacking our boners, and I felt really close, so I turned away, and he said 'NO man, let me see what you got'. He walked toward me, and pointed at the bench in the middle of the shower area. He stood at one end, and pointed at the other end. I stood at the other end opposite him. I told him I was close, and he said So am I.
I squatted a little bit, and let my load fly freely. I shot it almost all the way across the bench, and he was shocked. 'Whoa dude, let's see if I can beat that'. He jacked a little faster, and said 'Here it comes'. He came like a fountain, and it actually hit my legs. I jumped back, and he kept cumming like a fountain! I was really impressed. We went back to showering and after that I never saw him again in the showers until a few years later. He nodded at me, and I nodded back. I guess it's a little secret. I wouldn't mind doing it again though.
