For twelvemonth my sis and I had been courious about our bodies and had played the so called biz `` You show me yours and i 'll show you mine '' She was a year older and developed preferably then I so we really did n't recognise 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 nothing really happened early then giggling and asking questions about what we were looking at. She had started to develope boob and very fine fuzz had began to spring up around her vagina. I on the other deal had no hair development and was n't sure why. After about a twelvemonth of doing this I really did n't know what the big passel was because it just seemed pointless to me to see the same matter over and over. Then one morning I woke up and my phallus had become stiff 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 convention sizing and I was n't sure why. I was only 11 so I did n't make out what it ment. I had heard the great unwashed talking about sex before but did n't know what that ment either. When i seen my Sister the succeeding 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 certainly 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 grow again until it was pointing straight up at my abdomen. We were baffled at what had happened because we had never had anyone assure us what these affair ment. It was unusal but we just thought it was fun. We were tiddler and we had no idea it was what was supposed to go on when you start to hit puberty. A few calendar month went by when my babe came dwelling from a friends house and called me back to her room. She informed me that her ally older babe had a porn movie and they had took it and watched it. She said that the guy cable member in the movie had done the like matter that mine had done and that the missy had used her manus to stoke it up and down and it got bigger and great. She then began to explain what the miss did after it was much vainglorious 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 white meat and had even licked the girls vagina. I was more illogical then ever and did n't know what to reckon. 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 form of crazy and i was n't trusted what to say. I do n't get it on, what if it hurts or something I said. She said if it does we can kibosh. 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 pants down and she grabbed my penis and bagan stoking it. It did n't pain at all and my member began to get swelled and harder until I was fully rear. 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 suck her breast. I said ok. I started sucking on them and her nipples got rock severely. I asked her did they wound and she said no, it tickles though. After a few minute I said now what ? She looked at me and said I can do you if you want ? Shaking from being flighty i said ok. I stood up and she got down on her genu and pulled my pants back down and now my 4 inch erection was staring her in the face. She then slowly licked on the head of my penis as it bounced with every beat of my meat. Her tounge was delicate and it got me even more excited with every swirl it made around the tip until she opened up and took it in her backtalk. 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 ache ? I said no it feels unspoiled. She asked do you need me to stay fresh going ? YES I said. By now my coxa where thrusting forward and I could tell that this was something I was going to wish 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 teacher. When I look back on this moment i 'm not sure enough how she knew but her teeth never scratched or bit down on my member. For her low gear time she did an amazing job. So there I am, thrusting my hips while she sucked and sucked without stopping until something started to pass off. I was n't certain what it was but the feeling became more intense 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 minutes 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 mouth until I was finished though. After it was over she said she had forgot to tell me she seen it pass off in the telecasting. She looked up at me with cum dripping from her posterior lip and asked how it felt. I told her it was the advantageously 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 .
