That happened when I was 14.
Me and a friend met after school, it was at the beginning of the summer, he was the same age like me. He was in my class that time and it was the first time we done something together, because he was one of the cool boys. His name was Tom, he was something around 1,70 meter high, like me, well build because he played football and had blonde hair. He was one of the cool ones, because he was good looking so all girls liked him.
As we were walking around don't know what to do, he stopped and asked me, if I would like to see his favorit place in the wood. I said sure and we gone to the wood.
After a while going on a trail through the wood, he said we had to leave the trail. He walked in front of me and every pair of minutes he looked over his shoulder to see where I was. Than we came to a small lake in the middle of the wood, I never knew that there was a lake. The sun was shining and Tom said, that is it, it's beauteful isn't it. He was standing right in frond of me and in the same sentence he said he had to pee and opened his pants. He grabbed in to his pants and showed me his, I think 16 cm cock and said 'you too?' and moved next to me. I couldn't take my eyes off of his cock, nobody had ever before showed me his cock like that. While he was beginning to piss I said sure and took my, by that time 15 cm cock out. There we were standing in the wood next to each other and peeing on to the free ground. I was watching his cock while he was peeing and he knew it, so he began to make movements with his waist so he was peeing all over the place. We were laughing and I did the same.
After peeing he took out his balls and wanted me to do the same. I did and he began to come nearer and asked me 'did you ever jack off?'. I said yes, I was jacking off since I was 12. Then he pulled off his pants so I could see all his glory. He had blonde pubes and his cock and balls looked great. He began to play with his balls while I was showing him all my glory. I watched in his face while I done it and he watched my cock and at the same time he was walking to me. He was feeling my brown pubes and was moving his hand around my cock to my balls and groped them. First I was embarrassed but then I liked it, it felt so good to have another guy feeling my stuff.
I was doing the same to him and we were geting harder and we took off our t-shirts. We were all naked and feeling our stiff cocks. We began to kiss and rubbed our cocks together, he was touching my ass and then gone to his knees. He jacked my cock and with the other hand he played with my balls and ass, I was moving my waist as I was fucking. It felt so good.
After a short time I was cumming, my cum was all over him, it was the best orgasm of my life, at that time. The most cum landed on his face and hair and some on his chest. He took my cum from his face and stroked his cock with it. I gone to my knees too and began to return the favor. He was making horny noises and licked my cum from his hand.
He was cumming all over my chest, legs and cock, so the two of us had cum all over our bodies and we decided to go swimming in the lake. In the lake we made fun and rubbed our cocks against the ass of the other or grabbed the others cock.
While we were drying in the sun we ran all over the place naked. Before we wanted to go, we decided to jack again, we stood on a rock in the lake and blew our loads into the lake. Then we got dressed and walked home.
That was the best summer of my life at that lake.
