Water Polo Buddy

In 7th grade, I was part of my school's water polo team. When I first tried out for the team with my friend Billy, we hadn't played the sport before but we quickly grew to love it. Every Wednesday we went on a bus to the local pool to compete with teams from other schools. One Wednesday afternoon, we arrived at the pool to change into our water polo gear. Generally, water polo teams wear a helmet that protects the players' heads and ears. Some teams these days wear swim jammers, but a large majority still wear tight fitting speedos due to the freedom of movement they allow. My school's team wore plain blue swim briefs with our school logo and team name printed on the back. I always loved being in the change rooms and seing the other boys change. Most guys were still self-concious of their bodies and so they changed with their backs to everyone. For this reason, I usually wasn't able to see their penises, but I usually got a great view of their butts! I changed next to Billy and this time was able to get a quick view of his prick! It was semi-erect and was at 5 inches - fairly big for a 13 year old - and still mostly hairless. My glance only lasted a few seconds before we had to finish changing and go out to play the other school. The game lasted for an hour and by the end we were pretty worn out. We lost the game, but on the bright side I had a nice time looking at some of the fit players from the other school in their cool-looking red speedos! At the end of the match, before exiting the pool, I hugged Billy in the water as a way of saying 'good game' and for a brief moment our wet speedos touched. I felt a surge of electricity as our penises touched through the fabric. Immediately, I felt my penis rise to it's fully erect 4 inch state.  Billy hadn't seemed to notice and we got out of the pool to go back to the change rooms. It was even better to see the other boys almost naked when their bodies were wet and shiny. They looked great! I stood next to Billy near the changing room benches and started to pull my speedos down. Before I could do that though, Billy suddenly moved his right hand toward my crotch and groped my penis for a split second. It felt really nice and I quickly returned the favor. We both smiled at each other before returning to changing back into regular clothes. On the bus back to school, we sat at the back row and chatted to each other. A few minutes away from the school, I began to rub Billy's penis through his microfibre shorts. Everyone else was at the front of the bus and wouldn't notice. Within a minute or two, he cummed into his shorts and underwear. There was a tiny wet spot at the front, but it wasn't too noticeable. Billy started to rub my penis through my shorts, but after a minute he had to stop as we had arrived back at the school. Unfortunately, we couldn't do anything else that day as my mom had already come to pick me up. I was disappointed but decided I could jack off later that night. After eating dinner at home, I went up to my room, sat on my bed and opened up my laptop. I began searching the Internet for pictures of boys playing water polo and eventually stumbled across a picture of a teenage boy that looked similar to Billy. I took off all my clothes as starting jerking my prick up and down, thinking back to the moment when I hugged Billy in the water. Very quickly, something started to build up deep within me and soon rope after rope of cum exploded out of my penis and splashed onto my laptop screen. I fell back onto my bed in a tired but heavenly state, thinking about the things I could do with Billy in the future. At these thoughts, my sticky, damp penis began to rise again.
