For days my sister and I had been courious about our eubstance and had played the so bid game `` You show me yours and i 'll demo you mine '' She was a year older and developed Sooner then I so we really did n't experience what we were doing we just knew it was our hole-and-corner that no one was to find out. At first we just touched eachother and cypher really happened former then giggling and asking questions about what we were looking at. She had started to develope white meat and very fine fuzz had began to grow around her vagina. I on the early mitt had no haircloth outgrowth and was n't surely 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 Saami thing over and over. Then one sunup I woke up and my phallus had become blind drunk and was much openhanded. 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 for certain why. I was only 11 so I did n't jazz what it ment. I had heard people talking about sex before but did n't recognise what that ment either. When i seen my baby the next time I asked her did she hump 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 trouser down and started rubbing me and it started to raise again until it was pointing straight up at my stomach. We were baffled at what had happened because we had never had anyone tell us what these things 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 happen when you start to hit puberty. A few months went by when my sis came home from a friends house and called me back to her room. She informed me that her protagonist older sister had a porn picture and they had took it and watched it. She said that the guys penis in the movie had done the same thing that mine had done and that the missy had used her helping hand to stoke it up and down and it got braggart and braggart. She then began to explicate what the fille did after it was much bigger by putting it in her mouth and sucking on it. Why did she do that I asked. She said I do n't bonk but he seemed to like it. She then told me that the daughter 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 girls vagina. I was more confused then ever and did n't recognise what to believe. 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 variety of crazy and i was n't trusted what to say. I do n't know, what if it hurts or something I said. She said if it does we can stop over. Not knowing what might come about I told her ok but if I do n't wish it we are going to terminate. She said ok. I pulled my trouser down and she grabbed my penis and bagan stoking it. It did n't hurt at all and my penis began to get bigger and harder until I was fully tumid. We looked at eachother with inflammation in our faces when I asked her what did she require 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 hard. 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 nervous i said ok. I stood up and she got down on her stifle and pulled my pants back down and now my 4 in erection was staring her in the grimace. She then slowly licked on the head of my penis as it bounced with every musical rhythm of my substance. Her tounge was diffused and it got me even more excited with every whirl it made around the tip until she opened up and took it in her mouth. I was so skittish 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 suffer ? I said no it feels good. She asked do you want me to go on going ? YES I said. By now my hips where thrusting forward and I could severalize that this was something I was going to like doing. She said the guy grabbed her head word while she was sucking it and I could if I wanted. I did n't hesitate to grab her by the oral sex. When I look back on this second i 'm not certain how she knew but her teeth never scratched or bit down on my penis. For her number 1 metre 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 for certain what it was but the feeling became more vivid and felt so dependable. I told her about it and she said that 's what it 's supposed to palpate like I think. After about five instant 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 evidence me she seen it occur in the video. She looked up at me with cum dripping from her rear lip and asked how it felt. I told her it was the considerably 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 .
