Two weeks ago I saw something really neat. My son was going to have a pool party today, but there were thunderstorms and we had to cancel. But a couple of boys were already here, so I let them stay. They are all 11 and 12 years old.
The weather cleared up, so they went into the pool. My office is the old pool house that I have renovated into an office, and in doing so, I put film on the inside of the sliding glass door to reduce the heat gain. One beneficial thing about that is that you can't see into the office from the outside in the daytime. I was in there keeping an eye on the boys, and saw one of them found the water jet where the filtered water comes in. It is right about crotch level if you stand on a ledge in the deep end. I've used it to masturbate on many occasions.
Anyway, I saw one of the boys standing with his back to the jet, then he turned around and got a surprised look on his face as it hit him in the crotch. He looked around to see if anyone was looking, then put his crotch back in front of it and held it there for a while. One of the other boys, who spends a lot of time here, said to him "that's a great way to do it, it feels good. I do that all the time." He is 11. The first boy kept standing there, with an intent look on his face, then I could see he pulled the front of his suit down, and kept himself in front of the jet for about five minutes, then got real tense, and drifted off of it. I can't swear he had an orgasm, but I bet he did. I didn't get to see his penis, but I could see the look on his face, and that told me all I needed to know.
About 15 minutes later, another boy got on the jet doing the same thing. That boy only did it for a little while, and was replaced by a third on the jet. I just about blew my load watching all that.
Overall, four boys mounted that jet. There was the first one, who I'm sure orgasmed. Then two others who didn't do it long enough to orgasm, but did it repeatedly for a minute or two each time. They did it together; one on the jet, the other standing next to him waiting his turn. They, too, pulled their suits down in front.
Then, after all the boys had gotten out to go do something else, another boy came in, looking around furtively to make sure nobody was watching, then mounted the jet. He held it there for a little while, looked around again, and pulled his suit off and lay it on the side of the pool, then went back to work in earnest. I found out later that he is 13. He is a tall, skinny blond haired, blue eyed beauty.
He must have been in front of that jet for 10 minutes, and I could see him thrusting in and out, as though fucking the jet of water. I of course was jacking off watching him. It was neat; I could stand right at the sliding glass door with my shorts at my ankles stroking, and nobody could see me. I was really turned on by the sight of that boy on the jet, and had to hold back from cumming. Then I saw him arch his back and open his mouth as if to yell. He held on to the side of the pool with one hand, and held his penis in the jet with the other. Then I saw him shudder, and I came with him, all over the glass door.
As he relaxed, he floated backwards on the surface, and for the first time I could see his penis. It was long and thin, maybe 5 inches, but skinny. No visible pubic hair, but he obviously was well into puberty. I thought I could see a little glob of white stuff on the end of his penis, but couldn't be sure. He floated around like that until his penis deflated, then put on his suit and left.
I quickly went out to look at the water, and sure enough, could see small ribbons of white globs, so he had ejaculated into the water. Not a lot, but enough to be visible.
I thought I was finished, but when the boys gathered in the pool again in about an hour, the first one (the one who had come), mounted the jet again, and had a second go at it. Again I am sure he orgasmed, and didn't seem to mind that the other guys could see what he was doing. The other kid who came watched from the other side of the pool, and the two 'sharer's' went to it again, for several short stints on the jet.
That was a pool party to remember!
