My First Orgasm With My Cousin

This happened the summer after I turned 13. My extended family gets together multiple times each year on what we call the old family farm. The land has been in my family for a long time and at one time was a real farm. Now it is mostly just grass fields, a few small patches of fruits and veggies, and an orchard with some apple and peach trees. It was a really fun place to visit as a kid. Besides the modern house there are a few old barns and the old farmhouse and even a stream to swim in. I had decided to go with my grandma to the farm a few days early to help with the preparations for the big 4th of July gathering and we weren't the only ones who came in early. Some of my cousins were going to be there as well. The day before the 4th after lunch one of my older male cousins asked me to come with him to the old farmhouse. He was about 15 years old and I had a huge crush on him. I didn't expect him to do what he did when we got there though. He asked me if I had ever seen a penis before and I really didn't know what to say. I had seen them online and stuff but I never seen one in person. He said that he had never seen a pussy in person and that we should take off our clothes and show each other our junk. I was kind of scared and a little freaked out but also very curious to see what he had down there so I agreed. He went first pulling his shirt off and then pulling his pants down and there it has hard and sticking out straight from his body. I froze up like a deer in headlights staring at it until he waved his hand in front of my face and asked if I was going to get naked too. I imagine I blushed dark red and then stripped off my clothes as well. We stood there for a few minutes looking each other over and then he said I should get down on my knees in front of him so I could get a better look. I went ahead and did it and started looking him all over from various angles. He told me I could touch it if I wanted and I so reached up and felt of it. I was pretty timid at first but within a few minutes I was brushing my fingers through his dark pubic hair and feeling of his balls and pushing his shaft up and to the side out of the way to get a better look at it. I have no idea if I did this for five minutes or twenty but after a while he said he wanted to get a closer look at me and that I should lay back on the floor and spread my legs for him so I did. He started out just looking and he asked me to open myself up for him and I did. After a bit I felt him start to touch me. He starting by feeling my soft downy pubic hair which I didn't have much of at that time. I had never been touched down there by another person and I hadn't even given myself an orgasm at this point, but I was totally wet and horny from what was happening. He traced his finger around the outside of my labia and eventually moved inside. He started rubbing my clit and then worked a finger up inside of me and I started moaning and arching my back as I neared my first climax ever. I didn't know what was happening but it felt amazing and before long I was spasming and shaking uncontrollably. It took me a few minutes to come down and catch my breath and when I did I looked at him and he was smiling at me with this knowing look on his face. I asked him if he knew that was going to happen and he admitted that he did and that he had seen and played with a pussy before this. He then asked if I would like to play with him some and I agreed but I told him I didn't know what to do. He told me to wrap my hand around his shaft and start pumping it back and forth. After a few minutes of this he surprised me with a blast of thick white goo that landed on my arms, my chest, and even a bit on my face. I didn't really know what to do so I started giggling and he started laughing as well and he helped me clean it off and then we got our clothes back on and he gave me a kiss on the lips and we went about our day. That night as I lay in bed I thought about our little adventure and felt myself getting wet and reached down in my pjs to rub myself the way he had and gave myself another wonderful orgasm. The next morning I saw him and one of my other female cousins heading to the old farmhouse and I followed them. I peeked through the window at them as he told her the same stuff he had told me and got her to also go along with it as he had me. As I watched them I felt myself getting horny again and ended up playing with myself there in the bushes. A few years later I ended up telling the female cousin about watching them and she revealed to me that she knew our male cousin had done similar stuff with many of our female cousins and that the two of them had even had sex at another family gathering a year or so later. Every time I see him I kind of wonder what it would be like to be with him, but I've never approached him about it.
