For class my sister and I had been courious about our organic structure and had played the so called game `` You show me yours and i 'll show you mine '' She was a class older and developed sooner then I so we really did n't have it away what we were doing we just knew it was our secret that no one was to find out. At first we just touched eachother and goose egg really happened other then giggling and asking questions about what we were looking at. She had started to develope chest and very hunky-dory hair's-breadth had began to grow around her vagina. I on the early paw had no hair outgrowth and was n't trusted why. After about a year of doing this I really did n't know what the big deal was because it just seemed pointless to me to see the same thing over and over. Then one morning I woke up and my penis had become starchy and was much bragging. I was scared because I thought we had done something to it that hurt it or something. After a few minites it returned to the normal size and I was n't surely why. I was only 11 so I did n't know what it ment. I had heard people talking about sex before but did n't eff what that ment either. When i seen my sister the side by side time I asked her did she know what had happened and she said she had heard that it was what happens when you have sex. She said she wanted to see it when it got bigger but I was scared because I was n't sure how to do it again because it had done it on its own. She pulled my bloomers down and started rubbing me and it started to grow again until it was pointing straight up at my stomach. We were baffled at what had happened because we had never had anyone recite us what these things ment. It was unusal but we just thought it was fun. We were tike and we had no idea it was what was supposed to go on when you start to hit puberty. A few month went by when my baby came home plate from a friends house and called me back to her elbow room. She informed me that her booster older sister had a porno movie and they had took it and watched it. She said that the guys penis in the motion picture had done the Same thing that mine had done and that the girl had used her hired man to stoke it up and down and it got full-grown and grownup. She then began to explain what the missy did after it was much braggy by putting it in her mouth and sucking on it. Why did she do that I asked. She said I do n't know but he seemed to like it. She then told me that the girl had bent over and he had put it in her vagina. That 's when it hit me..they were having sex. She said the guy had also sucked on her knocker and had even licked the girls vagina. I was more confused then ever and did n't jazz what to think. After she was done explaining all this the question was asked. Do you want to try it and see what it is like ? It seemed kind of loony and i was n't sure what to say. I do n't know, what if it hurts or something I said. She said if it does we can stop. Not knowing what might encounter I told her ok but if I do n't like it we are going to stop. She said ok. I pulled my drawers down and she grabbed my member and bagan stoking it. It did n't wound at all and my member began to get bigger and harder until I was fully erect. We looked at eachother with excitement in our faces when I asked her what did she want to try first ? She pulled her top off and said let 's do what he did and nurse her breast. I said ok. I started sucking on them and her mammilla got rock heavily. I asked her did they hurt and she said no, it tickles though. After a few bit I said now what ? She looked at me and said I can do you if you want ? Shaking from being spooky i said ok. I stood up and she got down on her knees and pulled my pants back down and now my 4 inch erection was staring her in the face. She then slowly licked on the heading of my penis as it bounced with every beat of my nerve. Her tounge was soft and it got me even more shake with every swirl it made around the tip until she opened up and took it in her rima oris. I was so nervous all I could tell myself was i 'm ok..i 'm ok. After a instant or two she took it out and asked are you ok ? Does it hurt ? I said no it feels good. She asked do you want me to keep going ? YES I said. By now my hips where thrusting forward and I could severalize that this was something I was going to care doing. She said the guy grabbed her chief while she was sucking it and I could if I wanted. I did n't hesitate to take hold of her by the capitulum. When I look back on this moment i 'm not sure how she knew but her teeth never scratched or bit down on my penis. For her foremost time she did an amazing job. So there I am, thrusting my pelvic arch while she sucked and sucked without stopping until something started to happen. I was n't sure what it was but the feeling became more acute and felt so good. I told her about it and she said that 's what it 's supposed to feel like I think. After about five bit of her sucking me off the pressing had built up and I grabbed her head tighter and thrusted harder and harder until It happened. Niether of us knew what was happening as I started shooting cum in her rima oris. She never stopped or pulled it out of her mouth until I was finished though. After it was over she said she had forgot to tell me she seen it happen in the TV. She looked up at me with cum dripping from her bottom lip and asked how it felt. I told her it was the comfortably tactual sensation I had ever felt. I was so confussed about what had happened but I knew that we had to do this again. Just as we got done my mom came home so I told her we would do her later. She said ok and we went about our day .
