For old age my sister and I had been courious about our bodies and had played the so called plot `` You show me yours and i 'll show you mine '' She was a twelvemonth 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 oneself out. At first we just touched eachother and naught really happened other then giggling and asking questions about what we were looking at. She had started to develope knocker and very fine hair had began to mature around her vagina. I on the other hand had no hair growth and was n't for certain why. After about a class of doing this I really did n't know what the big bargain was because it just seemed pointless to me to see the same thing over and over. Then one daybreak I woke up and my penis had become potent 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 formula size and I was n't sure why. I was only 11 so I did n't hump what it ment. I had heard people talking about sex before but did n't know what that ment either. When i seen my sister the next 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 pants down and started rubbing me and it started to produce again until it was pointing straight up at my stomach. We were baffled at what had happened because we had never had anyone state us what these matter ment. It was unusal but we just thought it was fun. We were kids and we had no idea it was what was supposed to pass when you start to hit puberty. A few months went by when my sister came home from a friends house and called me back to her room. She informed me that her supporter older sister had a pornography movie and they had took it and watched it. She said that the guy rope member in the movie had done the same thing that mine had done and that the girl had used her hand to stoke it up and down and it got expectant 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 acknowledge but he seemed to like it. She then told me that the fille 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 tit and had even licked the girls vagina. I was more confused then ever and did n't lie with what to think. After she was done explaining all this the doubt was asked. Do you need to try it and see what it is like ? It seemed kind of nutcase 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 befall I told her ok but if I do n't wish it we are going to stop. She said ok. I pulled my pants down and she grabbed my phallus and bagan stoking it. It did n't injure at all and my member began to get freehanded and harder until I was fully raise. We looked at eachother with agitation 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 go down on her breasts. I said ok. I started sucking on them and her nipples got rock laborious. 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 nervous i said ok. I stood up and she got down on her articulatio genus and pulled my drawers back down and now my 4 inch erection was staring her in the nerve. She then slowly licked on the head of my penis as it bounced with every pulsation of my spirit. Her tounge was soft and it got me even more mad with every convolution it made around the tip until she opened up and took it in her mouth. I was so nervous all I could tell myself was i 'm ok..i 'm ok. After a moment or two she took it out and asked are you ok ? Does it hurt ? I said no it feels good. She asked do you require me to keep back going ? YES I said. By now my pelvic girdle where thrusting forward and I could tell that this was something I was going to like doing. She said the guy grabbed her point while she was sucking it and I could if I wanted. I did n't hesitate to seize her by the heading. 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 first-class honours degree time she did an amazing job. So there I am, thrusting my hips while she sucked and sucked without stopping until something started to happen. I was n't sure what it was but the touch sensation became more acute and felt so honest. I told her about it and she said that 's what it 's supposed to sense like I think. After about five mo of her sucking me off the pressure had built up and I grabbed her question 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 oral fissure until I was finished though. After it was over she said she had forgot to tell me she seen it pass in the telecasting. She looked up at me with cum dripping from her bottom lip and asked how it felt. I told her it was the Charles Herbert Best opinion 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 .
