My name is Cody, and I am 20 now. I have always been tall, skinny, and had dark black hair. Every summer when I was younger I would spend the night at my grandparents house with my cousin who is a year and a half younger than me. We would lay blankets on the floor and play video games all night. The summer I turned 13 was when things started getting interesting. We had been playing video games all night, after our grandparents went to sleep we decided to stop and do something different. I suggested that we play truth or dare. It started out harmless and switched to all dares. We were doing stupid stuff at first , then he dared me to run outside in just my boxers. So I did, came back in the house and sat back down in my boxers. My next dare for him was to run outside naked. He took off his clothes and I saw that his cock was soft and about 3 inches at the time. He did it then came back in and stayed naked, surprisingly. His dare for me was just to get naked. I told him that was lame, so he said ok then i dare you to go stand naked in the kitchen. I was kinda scared my grandparents would see me, but they didn't. I decided my next dared would be bold, so I dared him to touch my balls. He was hesitant but did it real quick. I said no that doesn't count so he did it for longer. As he did it I got semi-hard, so I told him he could stop. Well his next dare for me was to hold his cock. As I did, he got fully hard, about 4 and a half to five inches. I said well now you have to jack me off for 30 seconds. I was about 6 inches fully hard when he started. It turned me on quick, so I grabbed his cock and jacked it off as well. He stopped after a while and said I dare you to suck on my cock. I wasn't sure about it, but I figured hey we are just cousins. So I got don't and put my lips around his head. I felt some pre-cum and I started to suck back and forth. I got going pretty fast and noticed he was liking it alot. I decided I wanted him to suck me too, so I stopped, laid down, and told him to get on top of me. I didn't know it at the time but we started to 69. Once he was on top of me, his cock went far down my throat. After a while it was getting pretty intense and I couldn't hold it anymore and I came in his mouth. To my surprise he sucked it all up. I kept going to town on him, as he sat up some. When he finally came, I couldn't pull his cock out so all his hot cum went right down my throat. We got up, and decided it was time for bed pretty fast. That night we didn't do anything else, both the rest of that summer was fun...
