When I was 14 I had an experience with my step-brother who was then 15. I was very developed for my age and I later found out he was too.
His name can be Jon. We were out in the backyard and no one else was home. We were playing catch with a baseball. He said wanna play a game to see who drops it first? I said sure. He said the rules are whoever drops it has to take a piece of clothing of their choice off. I became turned on and decided to agree to play.
I dropped it first after a few throws, and so I took off my socks. Then we both eventually got down to our underwear/boxers and me I was in my bra. I really liked this game and wondered where it was going. Finally he dropped it and had to take off his boxers. He had to me (since it was my first penis) a big nice and firm penis. I liked seeing his penis, and I knew it was only fair to purposely drop the next two so he could have more pleasure.
So eventually I was naked as well. I asked what do we do now and he told me to follow him. There was a place in our backyard where you couldn't be seen, not that we needed to be hidden, but I liked the fact we were hiding. He told me to lay down and put my finger in my pussy and then he helped me jack myself off. It was a very long session. Then he told me to lay down next to him in the grass. He said to grab his penis and move it up and down, so I did. I squeezed it really hard, it was a very large and erect cock. He loved this and I squeezed and tickled it and he kept moaning. I loved doing this probably more than he liked it himself. He then rubbed his penis on my breasts and shot out cum on them.
I licked some of it and he as well licked it off. We then kissed and made out standing up while one of his hands came down and was fingering me and rubbing me down there and I loved it. I then threw my tongue in his mouth and my hand grabbed his cock and began rubbing it and squeezing it again. I loved this so much and I knew it had to end although I didnt want it to. He lay me down on the grass on my stomach and the feeling of the grass on my very wet and hot pussy was awesome. He lay on top off me and put his hand under my stomach and took three fingers and fingered me. I finally came. This later on led to another night alone that same day outside the backyard on the trampoline.
By then it was very cold so we both were in our underwear and I had my bra off. We naked wrestled on the trampoline and I finally pinned him and stuck my hand down his shorts and jacked him off. He then did the same for me.
There is another story but that's to come later.
