This happened to me when I was 15 years old. I remember it like it was yesterday.
One night my sister had this friend of hers spend the night with her. I knew this girl was pretty loose. And she was the same age as I was. My sister was 17 at the time. We all at up late playing cards. My sister said she was tired and she went to bed. This girl and I kept playing cards and in the back of my mind I was thinking that maybe I would get lucky that night. She was sitting across the table from me and all she was wearing was a night shirt and some panties. I could tell because I could see her big nipples through her night shirt. The longer we played cards I could not keep my eyes of of her tits and my dick was getting harder by the minute, and I was getting horny as hell. I don't know how, but I worked up the courage to put my foot on the seat of her chair. I slowly moved my foot to her pussy and started to rub her pussy with my big toe through her panties. I did this for about ten minutes and I could feel her panties becoming moist. Then all of the sudden she started rubbing my cock with her foot. She kept this up for some time and I finally had to tell her to stop or I was going to cum in my shorts. She then suggested that we go to my bedroom. I told her OK, but that we would have to be quiet because my room and my parents room were back to back. We went to my room and we started kissing and feeling each other up. Both of us getting hornier by the minute. I told her that I have never eaten any pussy before and asked her if I could eat her pussy. She said sure because she had never had her pussy eaten. I started licking her pussy all over and she began to squirm around on my bed, and started moaning. I had to remind her to be quiet because of my parents. I then started licking her clit and the squirming became more intense. Finally she bucked her hips in the air and let out a big sigh. She started rubbing the top of my head and told me that it felt great and that she had never orgasmed before that night. She then got up and pushed be back on the bed. She pulled my shorts off exposing my rock hard cock. She began to slowly suck my dick. I could tell that she had done this before by the way she was moving her head up and down on my dick. She didn't have to suck very long because I was so horny from having this girl's pussy in my face just I few minutes before. I told her I was about to cum thinking that she would finish by jacking me off. But she didn't. She kept sucking me off until I shot my load in to her mouth and she swallowed it all. I couldn't believe it, my first blow job and the girl swallowed my cum. She got up and thanked me for the fun and went to my sister's and went to sleep. I could not sleep all night thinking about what had happened. As a matter of fact I got hard again thinking about my experience and jacked off once more before I went to sleep. To this day that was the best blow job I have ever had and I probably won't forget it.
