For years my Sister and I had been courious about our soundbox and had played the so call in game `` You show me yours and i 'll show 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 hole-and-corner that no one was to ascertain out. At first we just touched eachother and nil really happened former then giggling and asking query about what we were looking at. She had started to develope breasts and very exquisitely hair had began to grow around her vagina. I on the former hired man had no hair growth and was n't sure why. After about a year of doing this I really did n't make love what the big peck was because it just seemed pointless to me to see the Lapplander thing over and over. Then one morn I woke up and my penis had become steady and was much with child. 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 citizenry talking about sex before but did n't sleep together what that ment either. When i seen my sister the next clock 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 adult 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 develop again until it was pointing straight up at my stomach. We were baffled at what had happened because we had never had anyone evidence us what these thing ment. It was unusal but we just thought it was fun. We were kids and we had no estimate it was what was supposed to happen when you start to hit puberty. A few calendar month went by when my babe came home from a friends house and called me back to her room. She informed me that her ally older sister had a porno movie and they had took it and watched it. She said that the guys penis in the movie had done the same matter that mine had done and that the missy had used her hand to stoke it up and down and it got bigger and bigger. She then began to explain what the girl did after it was much bigger by putting it in her oral cavity 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 boob and had even licked the girls vagina. I was more obscure then ever and did n't know what to reckon. After she was done explaining all this the motion was asked. Do you want to try it and see what it is like ? It seemed sort of crazy and i was n't certain what to say. I do n't have sex, what if it hurts or something I said. She said if it does we can stop. Not knowing what might come about I told her ok but if I do n't like it we are going to give up. She said ok. I pulled my pant down and she grabbed my penis and bagan stoking it. It did n't hurt at all and my member began to get cock-a-hoop 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 give suck her breast. I said ok. I started sucking on them and her pap got rock hard. I asked her did they wound and she said no, it tickles though. After a few instant 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 knees and pulled my drawers back down and now my 4 column inch erection was staring her in the face. She then slowly licked on the head of my member as it bounced with every pulsation of my heart. Her tounge was voiced and it got me even more excited with every swirl it made around the tip until she opened up and took it in her sass. I was so uneasy all I could tell myself was i 'm ok..i 'm ok. After a hour or two she took it out and asked are you ok ? Does it spite ? I said no it feels dear. She asked do you want me to observe going ? YES I said. By now my hips where thrusting forward and I could tell that this was something I was going to care doing. She said the guy grabbed her capitulum while she was sucking it and I could if I wanted. I did n't hesitate to grab her by the head. When I look back on this moment i 'm not sure as shooting how she knew but her dentition never scratched or bit down on my penis. For her first time she did an amazing job. So there I am, thrusting my pelvis while she sucked and sucked without stopping until something started to happen. I was n't sure enough what it was but the belief became more intense and felt so sound. I told her about it and she said that 's what it 's supposed to feel like I think. After about five minutes of her sucking me off the atmospheric pressure had built up and I grabbed her forefront 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 mouthpiece until I was finished though. After it was over she said she had forgot to tell me she seen it happen in the picture. She looked up at me with cum dripping from her bottom lip and asked how it felt. I told her it was the best 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 .
