Larry and Greg and I were at the lake one hot summer day fishing when we were in high school. The fish weren't biting and I was bored. I noticed Larry's nice cut cock was dangling out of the leg of his cut-off's as he sat on a rock drowning a worm and that Greg had a nice bulge encased in a pair of whitey-tidies hanging out the leg of his shorts.
Although I had seen Larry's cock before (and indeed was looking at it right then), I had never seen Greg's and I was wondering what it might look like. He was a lanky kid and I was imagining he had a long, uncut cock, probably similar to my own, which is about 7 inches and has a long foreskin.
After thinking about it for a few minutes I decided to see if I could get a look. I stood up on the rock I was fishing from and said I bet neither of those guys dared do what I was about to do. Then I stripped off my tank-top, stepped out of my shorts (freeing my semi-erect cock) and dove into the lake. Although it was a hot day the water was really cold and my hard-on became a mini in an instant.
There were a couple of boats out on the lake and a few other shore fishermen around, enough to make it a bit of a dare but it's a good sized lake and no one was really close enough to make it dangerous.
I swam around and climbed back up on the shore and sure enough, there were Larry and Greg, standing naked on their rocks, getting ready to jump in. Larry had a full-on hard-on going and Greg was semi-hard, his cock looking just like I had imagined it but about two inches longer! He was at least nine inches and his big cock-head was encased in a beautiful blue-veined foreskin.
'I thought you guys would be chicken,' I called out, and they both laughed and jumped in.
They swam around to where I was, laying on a patch of grass by the side of the lake. As they got out I checked them out and like mine, Larry's cock had shrivelled up to mini size but to my amazement Greg's was still long and although not hard it was flopping against his leg as he climbed out of the water.
We all laid there in the sun until we dried out and got warm and as we did we all started getting erections again. My seven inches were rock-hard and the tip of my cock was resting right on my belly button. I looked at Larry and his short, fat boner looked like a little beer can with a big purple head on it standing straight up in the air. Then I looked at Greg's and saw the biggest cock I had ever seen in my life, laying along his belly well past his belly button. It looked like a long hard snake and his veins were sticking out and throbbing.
I knew from being around those guys for years that I was going to have to be the one to start anything, so I just grabbed my cock and started stroking it, all the time eyeing their cocks, especially Greg's massive uncut rod.
Once I started, Larry started stroking his too, then Greg got his going. I asked Greg if he had ever measured his cock and he told me it was just over 10 inches long when it was hard. Then I asked if I could stroke it and he said he thought I would never ask.
He came over next to me and got on his knees, with that huge proud beauty poking straight up in the air. I took it in my hand and it felt so alive, so hot! I slowly stroked it up and down and as I did he took mine in his hand and did the same. Larry, who was laying there watching and stroking along, all of a sudden went 'Oh no!' and shot his hot cum all over Greg's back. Well, seeing that made me shoot all over too and before I knew it I was stroking Greg's spew right onto my face!
We had all cum together within a span of about 30 seconds!
We didn't do a lot more fishing that weekend, but we did have a lot of fun!
