If you don't then that's fine too. The beginning: I don't remember my mother. I was only three years old when she died and since then, my dad bought me up with the help of a succession of girlfriends. He did pretty well, turning up at most school things and, since he worked quite close to home, he was able to pick me up just after five from the neighbour where I went after school. Now I was ten, and would be starting high school after the summer holiday. Dad had been offered a promotion but it would mean me seeing less of him but I was old enough to realise that this might be his last opportunity, and also that we would be a lot better off financially. So now it was the summer holidays and dad had to go off to America for two weeks. He had arranged with his sister and her husband that I should stay with them. I had met them before of course, at family get-togethers, but I had never stayed at their house and dad told me that, if it worked out all right, it would become a regular thing. Apparently my uncle was away a lot, and my aunt would be glad to have a man around, especially now that she had a baby. The house was nice but it turned out that, because my uncle had a load of stuff stored in the spare bedroom, I was going to have to share with my twelve-month-old cousin. I wasn't very impressed with this because I had discovered masturbation and was wanking up to five times a day, and I thought it might be difficult with a baby in the room with me. It turned out to be less of a problem than I had expected. She was quite cute really, and it was fun for a while to play with her. She could only walk a few steps and crawled most of the time and we would play hide and seek, and I would build castles from her blocks for her to knock down. My aunt put her to bed before dinner and she was always sound asleep when I went up, and I soon found that my nocturnal activities did not disturb her in the least. Most days my aunt arranged to take us out somewhere. She didn't have a car so we had to travel on public transport which was quite a novelty for me. It was the beginning of the second week when things changed. By now I was barely aware of the baby in the room with me. There was a night-light on all the time and I changed into my pyjamas in the bathroom so as not to disturb her but on this night, just as I was having my final wank before going to sleep, she started crying. Naturally I got up to investigate and I could see that she was complaining because she had lost her dummy. I found it at the bottom of her cot and popped it back in her mouth. Then, as I stood beside the cot, and saw her suck that dummy in, I had an idea. A quick check assured me that no one else was up, so I went back to the cot, dropped the side, and pulled the dummy out of her mouth. Before she could complain, I quickly replaced it with my stiff little cock, and I can remember to this day the exquisite sensation of that greedy little mouth sucking on it like a vacuum pump. It was only about ten seconds before I squirted a small dollop of boy-cum into her mouth which she promptly swallowed. Then I replaced the dummy and went back to bed and slept soundly. The next night I could hardly wait for everyone to go to bed. I wanked myself to a climax just thinking about it while I lay there listening, and then I had to allow plenty of time for my uncle and aunt to settle down. Once I decided the coast was clear I got up and went to the toilet to check that the house was quiet and then carefully closed the bedroom door. My little cousin was lying on her side with the dummy in place as usual and she was reluctant to give it up. I was afraid that if she made too much noise my aunt would come in, but I thought I could say that I had just got up because she had lost her dummy. Eventually I persuaded her to let go of it and, once again, my cock was in her mouth. Because of my earlier wank I didn't cum as quickly this time and was able to enjoy fully the feeling of having my cock sucked by that innocent baby. Once again I squirted a small amount of cum into her mouth and watched as she swallowed it down. My aunt didn't go to work but was involved all kinds of charity things and she thought it was great that I seemed to enjoy playing with the baby and keeping her amused while she entertained her friends. I was getting confident too; no one expected a ten-year-old boy to be sexually abusing his baby cousin. When my aunt was having tea with the vicar in the sitting room, I was in the dining room keeping an eye on the baby in her playpen. My uncle had his computer in there but the only games he had were rubbish free ones. In those days the Internet was very slow and expensive, and I wasn't allowed to use it, so I started looking around his computer files see what else I could find. Most of his files were boring work stuff but, when I did a search for picture files, I found that he had loads of porn hidden away. My dad had some porn, magazines and pictures on his computer, but not like this. The first folder I looked at was pretty much the same as dad's, with grownups fucking in all kinds of positions. That was interesting enough, but the second folder was all about children. There were only about twenty pictures and half of them were just pictures of naked kids, but the other ten showed a little girl aged about six playing with a man's cock, and in one picture was actually sucking that huge cock into her little mouth. I went off to bed that night with images of enormous cocks, and eager mouths and cunts, and a cock so stiff that I couldn't pee, and I wondered if my uncle would want to copy the man in the pictures and get his baby daughter to suck his cock. I set my alarm for midnight and tucked it under my pillow, confident that by that time my aunt and uncle would be fast asleep and I would be free to play my secret game with the baby. Midnight came and I quickly killed the alarm. When I had been to the toilet and checked all was quiet, I tiptoed back to the bedroom and dropped the side of the cot. It was a warm night and she had been put to bed wearing just a nappy and a vest and, since she had already kicked her blanket off, I could see her chubby little legs and feet. I was pretty confident by now that we wouldn't be disturbed so, purely in the interest of research, I pulled the sticky tabs of her nappy and opened it up so that I could see her little pussy. She was lying on her back but her legs were together so all I could see was the crease where it started. As I watched she lifted her knees up and it was fairly easy for me to pull them apart allowing me a close-up view of her little baby cunt. I could see the whole of her slit with the puffy lips each side and what I assumed was her pee hole in between. I touched her gently with the tip of my finger and it must have tickled because she jumped a little bit but she still didn't wake up. Her skin was smooth, warm and dry, and when I saw the bottle of baby oil on the bedside table it gave me an idea. Carefully I tipped the bottle and poured a little down between her legs and, now that it was slippery, I was able to work my finger between those puffy little lips. As I stroked it up and down and eased the tip into her vagina I watched her face and, although she was clearly still asleep, it was obvious that she was enjoying the sensation. Of course I was stroking my cock with my other hand and suddenly I was coming and squirting my juice on to her belly. I used a tissue to clean her up, put her nappy back on, and a few minutes later I was fast asleep in my own bed. The next night she woke up. Once again I had her nappy open and my oily finger between her legs exploring her little baby cunt. I looked up at her face and saw that her eyes were open and she had lost her dummy. I thought for a moment that she would cry out and I was ready to break the world speed record for putting a nappy on, when I realized that she was smiling. There was no doubt that this baby was enjoying the feeling of having her pussy stroked and, as I carried on, she smiled and gurgled and her little hand came down to join mine. My cock was in my left hand and I moved round to see if she would hold it. I took her chubby little fingers and wrapped them around but she wasn't really interested so I offered it to her to suck. Like before she sucked it in as if it was one of her mother's nipples at feeding time. After having five wanks during the day I wasn't about to cum quickly, even though the idea that this baby seemed to be enjoying the whole thing as much as I was, was pretty stimulating. I stood there for a while with my cock in her mouth and my finger sliding up to the first knuckle in and out of her tight cunt where I could feel the barrier of her hymen, and I wondered what it was like to fuck a virgin and to break that barrier with my stiff cock. An image came into my head from one of my uncle's grown-up pictures which showed a man with his cock buried in a girl's bottom. I pulled my dick out of her mouth with a plop and replaced it with the dummy to keep her happy, then I lifted her legs so that I could see her bottom and the tight puckered hole of her anus. I spread some of the oil further down and I was surprised how easy it was to slip my finger inside. She was still happily sucking on her dummy and playing with her own oily pussy and she didn't seem to mind that two inches of my finger was buried in her bottom. By now I had been playing with her for nearly half an hour and I was getting worried about being caught so, reluctantly; I pulled my finger out and wanked myself to a climax, squirting a dollop of cum right on to her little pussy. The following evening I was determined that I would get my cock into that tight little bottom. I would have preferred to put it in the proper hole, but I was afraid that if I took her virginity I would be found out, and, anyway, her little bum looked just as inviting. I got up at midnight as usual but this time, when I went to the bathroom, I could see that there was a light on in my aunt's bedroom. With her awake there was no way that I could risk doing anything, so I went back to bed intending to stay awake and try later, but the next thing I knew it was morning and the baby was stood up in her cot crying loudly because she wanted her breakfast. Normally my aunt got up early and took her downstairs, but this morning she must have slept in. There was a tap on the door and she came in wearing a dressing gown and picked the baby up to quieten her. I was still in bed pretending to be asleep and my aunt, possibly forgetting I was there, sat in a chair, opened the top of her dressing gown, and offered the baby her breast. Once the baby was firmly attached and sucking contentedly on a big brown nipple, my aunt looked up and saw that I was watching. She smiled at me, but made no attempt to cover herself and just settled back in her chair allowing me a clear sight of her unoccupied breast. Unlike the ones I had seen in pictures, they didn't stick straight out but drooped down her chest. They were quite pale, almost white, and I could see the faint traces of blue veins under the skin. The nipple I could see must have been at least half an inch long, and was surrounded by a darker area of skin. After a while she pulled the baby's reluctant mouth off and switched her to the other breast. She took a tissue and carefully wiped herself and then, still supporting the weight of her breast with her hand, she looked straight at me. Once the baby was settled for the second half of her breakfast my aunt could easily have covered herself up but she didn't seem to mind that I was lying there gazing at those wonderful tits. Once the baby had finished my aunt put her back in the cot and then carefully cleaned herself with a wet-wipe allowing me one final look before covering herself up and becoming my respectable aunt again. Now I had two things to wank over; the baby's tight little bottom where I was determined that, before I went home, my cock was going to go, and my aunt's big tits and those brown nipples that I would have loved to suck. The second remained a fantasy, but the first I finally achieved on my last night. Once again I set my clock and this time the house was all quiet. I wasted no time and soon had her nappy open and my stiff dick substituting for her dummy. I poured a little baby oil between her legs and stroked two fingers between the lips of her cunt which made her lift her knees up and suck even harder on my cock. Holding her ankles with my free hand I was soon able to slide an oily finger up her anus and I could feel that tight ring of muscle squeezing my finger as it was going to squeeze my cock. I pulled out of her mouth and gave her dummy back, and then turned her sideways across the cot so that her bottom was on the edge in front of me. I spread her legs so that I could get between them and my cock was as stiff as a ramrod as I lined it up against that puckered little hole. At first when I tried to push it in it just bent and slipped out again, so I used a finger to open it up a little and then, at last, I was in. The sight of my cock buried as far as it would go in her bottom was enough to bring me off and this time I emptied my balls right inside her. Reluctantly I pulled my wilting cock out, replaced her nappy, gave her a kiss and slipped back into bed to dream of cocks and arses. That was my last night, and a few hours later I was sat in the front of my dad's car waving goodbye to my aunt and my baby cousin. Dad told me that my aunt and uncle was very pleased with me and that I was welcome stay there any time.
