Every Friday, I finish work in the early afternoon. One Friday, I decided to go to a pool in the city. There was surprisingly many people there, I guess because of school holidays. Anyways, I changed into my blue jammers and swam laps for about two hours.
When I went back to the men's change room, there were quite a number of guys getting changed, so there wasn't very much privacy. Oh well. I put my bag on the bench and began stripping off my jammers. I noticed a boy standing next to me: Asian, about thirteen or fourteen, with a nice swimmer's body. He was pulling off his black swim briefs. I know I shouldn't have, but I curiously looked at his genitals.
I was a bit surprised at how big he was downstairs. At least 5 1/2 inches, much bigger than I was at that age! Also, he was semi-erect and had a fair amount of pubic hair. The boy noticed me taking a brief glance and grinned. I shyly looked away and walked straight to the showers with my towel. He took the stall next to mine. The shower stalls had doors you could close for privacy, with thin dividers separating them. The dividers were fairly high, but there was a gap near the floor. You could see up to the knees of the person next door.
I started to shower, quickly becoming erect. After a few seconds, I glanced down at the floor. What I saw was the shadow of the boy in the next stall, with his hand furiously pumping his dick! Of course, I had to do the same! After about a minute, I saw the boy's shadow wiggle slightly, with large white globs landing on the floor, slowly making their way down to the drain. As soon as the first white glob hit the floor, I started shooting. Three or four long ropes of cum landed on the floor in front of me, making its way to the drain at the edge of the wall.
I used my towel to wipe my body clean, then went back out to change back into regular clothes. The boy followed me soon after and we changed together. Between putting on each item of clothing, we looked quickly towards one another and smiled. When we had both finished changing, he left first. I began to wonder if I would see him again...
