I was already in the jacuzzi when he came around from the shower area. There were kids at one side of the jacuzzi and a few other guys in the jacuzzi on the side near me. The kids and their dad left, and he moved to the other side of the jacuzzi. There was water falling from the rocks above into the pool of water that was the jacuzzi on that side. I wanted to know if the water was cold enough to be soothing for me, so I went over there as well.
I sat under it, but it wasn't cold enough for me. I tried to get comfortable in front of the jet, but it was set too low. The guy was sitting at the other waterfall a few feet away from mine, and there was another jet to his left. Being the horny 20-something that I was, I got up and said the jet wasn't doing anything for me and moved to his other side because I wanted to actually loosen my muscles after working out, but I was curious about the guy too. The jet he was at and the jet I was at was closer than the one I was at before, and my hand would easily be able to reach him if he was interested.
We started talking a little bit about how we've seen each other before and how long we've been going to the gym. As we were talking, my foot grazed his under the water. I moved it away in case he wasn't interested. I moved my foot over to his again, moved it away again, and then put it down. I incidentally put my foot down on his. He must've moved it since the first time I touched it. I left mine there, and he left his. At this point, I figured he was either curious enough about me as well so I moved my foot up his calf a little bit. As we were talking about the workouts we do, where we work, and where we live, his hand started stroking my dick. I didn't stop him, and we kept talking. He asked if I lived alone, and I said no, which I'm not, but I got the idea that he wanted more than just a handjob in the jacuzzi. At this point I was already hard from thinking of the prospect of getting a handjob from this guy. I didn't know if he'd be ok with it when I moved over there, but apparantly he was. I didn't let him go too far because I didn't want to get close to cumming in the jacuzzi.
He introduced himself as Ken, and I shook his hand. Then I drew my hand down and touched his dick. It was a little bit thicker than mine, but the head was what was the real difference. This only being the second handjob I've done (or had done to me), I explored it a little bit. I stroked his dick for a while, then felt around the head and piss slit, stroking up and down, drawing my fingers around the circumference, and squeezing it. After a couple minutes, I moved my hand to his balls. I took his right one in my hand and started to roll it around. It was not exactly the size of a golf ball, but it was close. I kneaded it in my hand as we talked. I moved my hand over to feel his other ball. I did the same thing, but his other one was significantly smaller than the right one.
I eventually took my hand off, and he started stroking me again. His hand then went around to my butt and started feeling up and down. He gave my cheeks light sqeezes and felt up and down my crack. He started putting more pressure on his strokes, probably trying to get to my anus. I didn't let him get too far in, but he stroked his fingers up and down my crack.
