One time my dad, little brother and I were going camping. We shared a tent and my dad had his own. One night my little brother and I decided that it would be a good idea to take a shower. He said ok. When we got there no one was in the showers since it was so late. There were tables on one side of the building for your clothes. On the other side there were showers.
So we took off our clothes. It wasn't a big deal to see each other naked since we were guys and had nothing to hide including our cocks. Since it was one big open room we could see each other. Then I felt my dick get harder, I looked at my little brother's dick, it was fully erect. Then mine was too. We weren't trying to hide it or anything. Then my brother said man I wish I had a cock like yours. it's so big and hairy. I told him, your cock isn't that small. His was about six inches. Mine was about seven and a half inches. We both had hair and was uncut. We were also very skinny. Our butts were very tight and muscular.
I asked him if he had ever seen a naked man before. He said only me and my dad. He told me he fantasies about seeing me naked. I then asked him if I could touch his penis. He said ok if I can touch yours. So we grabbed each other. It felt so good. We were doing each other for about five minutes. Then we started to moan, and came all over each other. That night we slept in one sleeping bag both naked.
We still masterbate in front of each other. We often take showers together. One time our dad walked into my room when we were at it. But he was cool. He gave us some porno. Since it is only me, my dad and brother living in the house, he said we could do in any time we wanted to, in any part of the house. We like to do it in the living room.
