Reading these stories always reminds me of my early sex experiences.
This happened when Jim and I were about 16. I had my driver's license for a few months when we decided to drive out to a little lake for an afternoon swim. When we got to the lake, there were a few others there, so we changed into our swim suits in the car. I got into the back seat to change. Jim kept looking over his shoulder at me as I got out of my clothes, and when he saw my naked dick said,
Your prick looks bigger. What have you been doing to it?
Nothing, I replied.
Yes, you must have, he insisted.
No, just regular jacking off, I said, and we got out of the car, and went to swim. We swam out a ways, then stood up and resumed our conversation. He suggested that we get out of our swim suits, so we did. The water was clear, so we could see each other's dicks which were by that time very hard. Mine was 7 inches, and his was a little smaller. He moved closer, and reached for my dick with his thumb leading. That was the first time anyone other than I had touched my dick since childhood. I enjoyed the sensation which he realized as he kept moving his hand over it as if he were milking a cow. Soon I was breathing heavily, and he took my hand and placed it on his dick. Now we were jacking each other. We kept this up until we both shot huge loads of come into the clear lake water. That's how we became jack off buddies.
