I imagine other men have experienced this when they were teens. I would go to my friend, Tony's when we were both 15 or so and shoot basketball hoops in front of his garage. One day I noticed he had a large boner and I took a grab at it, kiddingly. He said, "Do that again and I'll fire off a huge load." Just for fun, I said, "let's go in the garage and you can show me." We went in his garage and closed the door. Tony pulled out a cock as large and as thick as my own and I eagerly started to jerk him off. He wrapped his big hand around mine, not quite reaching around with his fingers and we began to beat each other off, our hands both filled with large, hot and hard cocks. We were both quickly heating up. We were both cut, with large heads.

Soon, facing each other, our hard, throbbing cocks were clustered together and we took turns jerking off our cocks together, clutching the bundle of cocks in one or two hands. In a few minutes, we blew off our nuts, firing cum all over each other almost simultaneously. When I saw him coming, I immediately started to shoot off as well. As much as we both enjoyed it, it never happened again as we were both admittedly starved for pussy. A year later we talked about doing it again, but soon after our plans, my family moved out of town and of course, I with them.

I did think of Tony's hard, meaty cock long after that. It was the twin of mine so a perfect mutual wanking.
