He's my nephew by marriage. I've seen him grow up and been around him forever. I don't know why that night felt different but there was a different air about him. It wasn't the first time we had been alone but something just felt different. We sat on the sofa watching a movie when he surprised me with a forceful kiss, his tongue demanding as it pressed into my mouth. I instinctively kissed him back. It turned into a long making out, and touching lightly all over, but not anywhere really inappropriate. We were doing it for half an hour at least when I felt an almost sudden rush through me and to my own surprise I came.....just from a make out session. Then I reached down in his shorts and slowly stroked his young cock ass we made out and his hands were inside the top of my night dress. He made a mess in my hand and his shorts. I pulled it out, and licked my fingers, which made him a little wild. He pushed me on my back and got on top of me and started kissing me harder, and humping me. His hard cock was directly against my pussy, through layers of the clothes frustrating me. I was almost relieved when I felt him reach down to pull down his shorts and his cock sprang free, and pressed directly against my lace panties. He was back in his rhythm in moments, and I could hardly concentrate on kissing, he was sliding right over my clit. He made me cum again, and I had to push him away for a moment. It was too intense. He was playing with my nipples - pinching, petting, licking, sucking. But I was too sensitive down there to let him rub against it again like that. So I pulled my panties down and turned over on to my stomach. He eagerly began grinding his cock against my cheeks, but that was a bit boring for me after a minute or two. So I moved a little and his bare cock was now sliding between my legs against my pussy. I was so close to cumming when I felt him tense up and start making a wet mess under my stomach.
