If you don't then that's fine too. My Journal 1999 Sunday April 28th Mum gave me this journal for Christmas but this is the first time I have had anything interesting to write about. This evening though... Wow! Do you think it's possible to fuck a little girl, while she is sitting on your lap, without her mother noticing, even though she's in the same room?If you had asked me that question a week ago I would have laughed said it couldn't be done but now... My sister Amanda is six years older than me but you wouldn't know it to look at her; slim and petite, she weighs in at less than 50 kilos soaking wet. You wouldn't want to get on the wrong side of her though, since she punches well above her weight. Amanda's ten-year-old daughter Cindy is nearly as tall as her mother already, all arms and legs and just beginning to develop tits. Her father buggered off about a year ago to live in a caravan with a sixteen year old girl who was already pregnant by him. I was glad to see the back of him but Amanda was pretty upset. My social life is pretty nonexistent at the moment so I spend quite a lot of time at her house. Things are not so good at home either, with Mum and Dad arguing a lot and my identical twin sisters Amy and Kim always squabbling, so it's nice to be somewhere where I can get a bit of peace. I wouldn't say that I had never had a sexual thought about my pretty little niece, with her big brown eyes, cute smile and slim athletic body. Even when she was a toddler and I helped out at bath time I would get aroused at the sight of her smooth bare little pussy, but I never dreamed that one day I would be planting my stiff prick in there. Was it naïve of me to think that it wasn't unusual for a ten-year-old girl to want to sit on her uncle's lap? I didn't think so and, to be honest, I liked it and she seemed to enjoy teasing me. I did find that it was best to have a wank before I went there so I wouldn't be embarrassed by unwanted erections. So we come to this evening. Amanda and I were sitting watching TV; she was sprawled on the couch and I was sitting in an armchair, when Cindy came down from her bath. She was wearing one of her mother's bathrobes which came right down to her ankles and it was no surprise when she came straight over and plonked herself down on my lap. Of course I put my arms around her and gave her a kiss as she wriggled around herself more comfortable. I knew that in doing so she had shifted the robe from underneath her bottom and, even though I had wanked as usual less than an hour before, the thought of her bare little bum separated from my cock only by the tracksuit bottoms that I was wearing, made my cock react. I knew she had noticed because she gave me a cheeky grin and began a slow wriggling grinding movement on my lap which made me more and more uncomfortable. She lifted herself up slightly and, to my astonishment, put her hands down inside the elastic of my pants, caught hold of my semi hard cock, and moved it to a more comfortable position on my belly. Amanda told her to stop wriggling around, and told me to chuck her off if she was being annoying. Cindy just giggled and sat still for about thirty seconds before she began to work the waistband of my pants down so that her bare bottom was directly on top of my exposed prick. I didn't know what to do. I looked at my sister and she was concentrating on the TV, seemingly unaware of what her daughter was doing. I was too embarrassed to make a fuss and I didn't dare (or want) to say anything so I just sat there. Of course none of this was visible because the robe she was wearing covered us both completely; and then I thought "what the hell" and decided that I might as well see how far she would go. Carefully I eased forward on the chair and at the same time pulled my pants further down out of the way. Cindy realized what I was doing and lifted herself up and sideways to get the shaft of my rigid cock between her legs. She more or less had her back to her mother and I was able to get my left hand beneath the bath robe to get my fingers on her pussy without being seen. I could feel the head of my cock, all slippery with precum, pressed against that smooth little cunt so all I had to do was give it a little push and then I was in her. How I didn't cum instantly I will never know. She was so tight that it was painful. I am sure that if I hadn't had a wank an hour earlier, I would have exploded in her straight away. As it was, I had to bite my lip hard and recite the seven times table so that I could hold back. I could scarcely believe that Amanda wasn't aware what her sexy little daughter was doing but she seemed to be totally oblivious as Cindy just sat there on my lap with her breath coming in little gasps as she slowly eased herself down until the whole 15 centimetres of my manhood was buried her preteen cunt. In spite of the mental arithmetic, I knew there was soon going to be a problem, so I fished in my pocket for a handkerchief and pretended to wipe my nose, so that when I couldn't hold on any longer, and shot a load of incestuous cum right into my little niece's belly, I could use it to wipe up the mess. I held her tight as my cock swelled and my balls began to pump what seemed like a gallon of spunk up the shaft. At the same time I could feel Cindy's muscles spasming as she went into her own orgasm. For the next ten or fifteen minutes we just sat there while Cindy came back to earth and my cock shrank enough to slip out of her. Then, saying she needed the loo, Cindy stood up just slowly enough to allow me to get my handkerchief wrapped prick back into my pants, and ran off upstairs. Amanda stood up as well and I thought for one horrible moment that she had seen what I had done, but she just asked me if I wanted a beer, and when I nodded, went off to the kitchen and came back with two bottles. I just sat there, drinking my beer, scarcely able to believe what had happened; in fact thinking about it now it seems like a dream, a dream come true maybe, but a dream nonetheless. Cindy called down to say she was going to her bedroom and then Amanda made a little speech about how grateful she was that Cindy and I got along so well. She told me that I would be a wonderful father one day and, when I had to go home, she confused me even more by giving me a very un-sisterly kiss. As I walked down the road I couldn't help wondering if my sneaky big sister knew perfectly well what was going on all the time.
