I am 18 years old. I went to North Carolina to visit a cousin of mine. Her husband was a marine and had been deployed and her family was over to visit. When I got there the rest of her family, except for one sister, had only three days left to stay. Among them was her younger brother, my cousin, who was fourteen, 4 years younger than me. While growing up he was my best friend and as we began to grow we began to experiment. He came over to my house a lot, and while my parents were gone, we would strip for and touch each other. As we began to grow older, our curiosity began to increase. We scaled up to kissing; then oral and eventually trying anal. He was still young and his peinus was still to small for me, so I was always the one on top. Although it felt good, he didn't really like it. And as he reached his pre-teen years he no longer wanted to try anything else. It had been almost 2 years now since we had tried anything. Seeing him shirtless, I could tell that he was no longer the little boy who used to "play games" with me, he was growing older and his body was maturing... it was really turning me on. My first night there, we made sleeping arrangements. He and I would be sharing a room, but we would have to sleep on the floor. We were both fine with it. The first two nights he slept fully dressed, but the third night. They would be leaving the next morning and all was packed up. He came to bed in nothing but a pair of boxer-briefs of. I tried to keep my composure as I stared him down from top to bottom. It was around midnight when he fell asleep. I moved my leg and felt it rub against his. I could feel his body heat and it turned me rock hard. His back was facing me I was slightly below his shoulders. I reached my hand over and lightly began to touch his butt cheeks, which were stiff and muscular. My heart pounded as he rolled over to his stomach, but he was still asleep. I lifted my leg and laid it on his. He rolled over his back to me again. I pulled my stiff rod out of my pants and began to rub it against his butt over his briefs. But his ass wasn't all I wanted to feel. I put my arm around his as if to give him a hug, but reached lower than his abdomen. I could feel it, it was stiff and significantly larger than the last time I had felt it. I was satisfied. I began to pull my hand away but then, his hand grabbed my wrist. My heart was pounding, but as I was about to apologize, he pulled my hand in closer to him and set it back where it was... I knew what he wanted. I began to touch it, he was stiff as a rock as well not too, though he wasn't too large: about 4" long. I rubbed his abdomen then reached my hand down into his briefs. I could feel his freshly growing pubes in my hand and as I reached further in, I could feel his wet pre-cum. He reached his arm back and began to masturbate me, so I returned the favor. He then faced me and stuck his tongue in my mouth. We kissed and played with each other for a while. Then I went under the covers and put his in my mouth. It tasted so good, I couldn't get enough; I loved his cock in my mouth and he held my head in place. Then he pulled me up and did the same for me. I was pleased, but I wanted something else. I pulled him up and turned my back to him... he knew exactly what I wanted. He pulled my pants down to my knees and drew me in closer. I had never done this before, but he didn't know that. He played with it between my cheeks for a while before he got down to business. He began to shove it in; it was so good I wanted to moan, but I didn't in fear of waking anyone up. He got it in and began to pick up speed. I could tell he was enjoying it. But then he pulled out. He laid on his back and began to jack off, so I did the same. He stuck his hand under my ass and began to rub and squeeze my cheeks. I was in heaven. I could feel it coming so I bit my lip. He rubbed my inner thigh and balls to encourage me and then... aahhh, relief. He instantly stopped what he was doing and went under the covers: he wanted a taste. He licked it all up and then sucked me some more. Then he resumed where he had left off, squeezing my cheeks and touching himself. He began to pick up speed and I knew it was coming. He vigorously began to squeeze my ass as he panted like a wild animal, then his hand relaxed as it laid under my ass: I knew he had came all over himself. I with I could say I licked it all up for him, but I didn't. We let go of each other and with one final kiss, our fantasy night was over.
