For years my sister and I had been courious about our physical structure and had played the so name game `` You show me yours and i 'll depict you mine '' She was a year older and developed sooner then I so we really did n't know what we were doing we just knew it was our secret that no one was to find out. At initiatory we just touched eachother and naught really happened early then giggling and asking questions about what we were looking at. She had started to develope breasts and very fine hair had began to develop around her vagina. I on the early handwriting had no hair development and was n't sure 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 matter over and over. Then one morning I woke up and my penis had become stiffly and was much bigger. 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 sure why. I was only 11 so I did n't know what it ment. I had heard masses talking about sex before but did n't know what that ment either. When i seen my sister the next prison term I asked her did she love 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 indisputable how to do it again because it had done it on its own. She pulled my pant down and started rubbing me and it started to uprise again until it was pointing straight up at my abdomen. We were baffled at what had happened because we had never had anyone tell us what these thing ment. It was unusal but we just thought it was fun. We were tike and we had no approximation it was what was supposed to happen when you start to hit puberty. A few months went by when my sister came home from a Friend business firm and called me back to her room. She informed me that her friends older baby had a smut motion-picture show and they had took it and watched it. She said that the guys penis in the movie had done the Lapp thing that mine had done and that the fille had used her hand to stoke it up and down and it got bragging and bigger. She then began to explain what the girl did after it was much bigger by putting it in her mouthpiece and sucking on it. Why did she do that I asked. She said I do n't bang 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 breasts and had even licked the young lady vagina. I was more jumble then ever and did n't experience what to believe. After she was done explaining all this the inquiry was asked. Do you want to try it and see what it is like ? It seemed variety of crazy 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 happen 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 penis and bagan stoking it. It did n't ache at all and my penis began to get bragging and harder until I was fully tumid. 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 soak up her breast. I said ok. I started sucking on them and her nipples got rock concentrated. I asked her did they hurt and she said no, it tickles though. After a few minutes 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 headland of my member as it bounced with every metre of my bosom. Her tounge was soft and it got me even more excited with every swirl it made around the tip until she opened up and took it in her lip. I was so spooky all I could tell myself was i 'm ok..i 'm ok. After a second or two she took it out and asked are you ok ? Does it hurt ? I said no it feels practiced. She asked do you need me to hold going ? YES I said. By now my hips where thrusting forward and I could tell that this was something I was going to like doing. She said the guy grabbed her head while she was sucking it and I could if I wanted. I did n't hesitate to grab her by the chief. When I look back on this moment i 'm not sure enough how she knew but her tooth never scratched or bit down on my penis. For her first base time she did an amazing job. So there I am, thrusting my articulatio coxae while she sucked and sucked without stopping until something started to happen. I was n't sure what it was but the touch became more intense and felt so good. I told her about it and she said that 's what it 's supposed to sense like I think. After about five bit of her sucking me off the pressure 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 mouth. She never stopped or pulled it out of her back talk 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 in force feeling 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 .
