This happened to me when I was 13 and camping in Boy Scouts.
My friend named Matt and I had known each other probably since we were 9, and I knew this kid was one of those kids who had experimented with others and was a pornomatic. We were camping on a cold winter night and started talking about j/o and girls and all tha. The next thing ya know, he pulls out a deck of cards that have porn on each one
I said, hey didn't you show dick shadows on the tents with your friend Ian? He then pulled out his dick and showed me what he did. The next thing you know he is j/o and I am j/o and I cum but this kid had j/o so much in his years he would have to go for a while to cum. So then he's like i'm gonna cum and starts going really really fast on himself. He ended up cumming. That night I went to sleep warm and sweaty in my sleeping bag. It's a crazy night I will never forget.
