The day was hot and I had just finished cutting our lawn, when Jen a classmate of mine, stopped by and asked if I would like to come to her house and have a soda. I agreed and we headed for her house. Now Jen was beginning to mature into a young woman as she was getting curves and her breasts were enlarging.
Once at Jen's house, we went inside and I sat on the sofa while Jen got the soda's. We sat next to each other on the sofa and drank our soda's and when we finished, Jen asked me if I had ever seen a girl naked. I answered no and she said that she would get naked if I did the same. Being a hot teenager, I agreed to her request.
Jen got up and proceeded to take her top and bra off to reveal her budding breasts. They were the size of lemons and her nipples were very erect. Next she removed her jeans and panties to reveal her fuzz covered pussy. She then asked me to take my clothes off. It did not take me long to remove my jeans and shorts and here I was standing naked in front of a girl. Needless to say my cock was at full erection. Jen reached over and put her hand on my cock and began to squeeze it and then to stroke it. I just stood there as she continued to massage my cock and in a couple of minutes I began to feel the beginning of my climax. After a couple more strokes, I began cumming and sprayed my juice all over her. She looked at me with a big smile and asked if that felt good. I told her it was wonderful.
Jen then went to the sofa and sat on the edge and spread her legs exposing her pussy and told me to come over and feel her. I went over to her and put my hand on her pussy and she put her hand on top of mine and showed me how to stroke her pussy. She was extremely wet and after a few minutes, she put my hand on the top of her pussy and told me to rub her there. I could feel a little hard spot here and she told me to rub around it in circles. I did as she told and she began to squirm a little and began to moan. She put her hand on top of mine and pushed it hard down on mine and pulled her legs together and I felt her legs twitch as she moaned louder. After a few minutes she relaxed and told me that was the greatest feeling she had ever had.
With all of her moaning and such, my cock was hard again and without any help began to jack off in front of her. I pointed my cock at her and shot my jism all over her.
This was the first time I had mutual masturbation with the opposite sex. Needless to say, we continued to do this for some time and of course it lead to other things as well.
