Dear readers I really enjoyed relating my previous experience that I have decided to tell you of another true experience I had. I am married, two children, aged 40 and live in London. My wife, Rani, is very pretty and has still a very nice figure but unfortunately cannot handle more than once a week sex, whether it is due to the large size of my tool or she has low sex drive I am not sure. However I find my tool actually makes me more popular with other woman, so this is not really a problem. The experience I am about to relate happened 3 years ago. My brother's son was getting married and my wife and I were required to help with the preparations a few days before the wedding. As we were going to stay the night we needed someone to baby sit our two young sons, my wife asked her sisters 17 year old daughter Sonia, as they lived quite close by, to come and stay around our house. Not only would she look after the boys but also the house, we had quite a few valuables with the wedding coming up. We left Sonia in charge and left for my brothers at around 6pm and got there around 7.15pm. When I took all the stuff out of the car I realised I had left behind my state of the art video camera with which I had promised to record all the small preparation ceremonies. My wife was not impressed, as this was the main reason I was there, she decided I should go back and get it while she helped the ladies in the house. I was really annoyed with myself and apologised to my brother and drove back to our house. As it was nearly 9pm and the house was all dark I let myself in quietly as not to disturb anyone, I knew where the video was and quickly went to the front room and got it. I was about to shoot back out when I heard low talking and noticed that the lounge light was on and the door about 2/3 inches open. I was surprised because the boys 6 and 8 would normally be asleep by 8pm and there was only supposed to be Sonia there. When I looked through the gap in the door although I was shocked at what I saw, I immediately switched on the video I was already holding. Sonia was completely naked sitting on the sofa with a boy around the same age as her standing in front of her. The boy had his trousers around his ankle, his 5 inch dick was semi erect and Sonia was trying to suck to a full erection. The boy was obviously new to this as he was not only shaking but very embarrassed because he kept apologising for having come so early in his trousers and spoiling everything. Sonia had always been just a child to me but I could easily see she had grown up in a very nice way. She had a very slim light tanned body with small but firm boobs, the nipples were standing and she looked like she knew how to suck a cock, my cock had gone hard the minute I had seen the them. Sonia had finally managed to get a good erection and she lay back onto the sofa still holding his dick, the boy had just climbed onto the sofa and was about to with Sonia's help guide it into her. Although I was enjoying this I felt duty bound to stop it, I charged in acting very angry demanding to know what was going on. I dragged the boy off and slapped him a few times very hard, he tottered towards the door, pulled his pants up and shot out of the door I chased him out of the house cursing him. I returned to lounge to find Sonia running around collecting her clothes, she was almost hysterical and panicking. I got a full nude frontal, she had a perfect round pert little bum and a small tuft of public hair on her pussy ,before she collapsed onto the sofa with her clothes in front of her. She burst into tears and hid her face in shame. I did not know what to say, I was not really angry, all I could manage was "what the hell did you think you were doing, what will your parents say" "I'm sorry, please don't tell my father" cried Sonia, "he will kill me or worse marry me off ". I thought Sonia was already upset but the thought of her father finding out terrified her so much she jumped down, forgot her clothes and clung to my leg. I was shocked at this naked girl clinging onto my leg and continuously begging me not to tell her father. "But I have to tell your parents, you must be put off doing this again, they have to set the punishment" I replied starting to feel sorry for the poor girl. "I won't do anything like this again I promise, why don't you punish me, I'll do anything just please don't tell my father" she pleaded with tears running down her cheeks. I said no, I did not how to, but she kept begging and crying. Finally I said that I had caught one of her cousins smoking a cigarette and had managed to punish him and put him off smoking again. She brightened up and begged me to punish her the same way . I said "I made him smoke a cigar which had made him very sick and put him off smoking completely, but I can't do that with you." "Why not? " she said starting to cry again. "because you were not caught smoking a cigarette" I replied, watching her very closely. Sonia's eye widen and mouth dropped , she let go of my leg and crawled back to the sofa quickly, "you can't mean......you're sick" she shouted looking angry trying to cover herself up but looking directly at my tent. "No I didn't mean anything, don't be stupid" I replied trying to look calm "I was just saying I can't think of anyway out of telling your parents" Sonia looked confused and panicky again, finally she said" If I did, would you promise not to tell my parents". Although I was dying to ram my dick in her mouth, I calmly told her not to be stupid she was my niece and we could not do anything like that it would be sick. I could see the desperation in her eyes as she slowly came forward again, dropping her clothes and with no effort to cover herself. "please let me, this is so sick that it will ensure I never do anything like this again" she pleaded. I pretended to be shocked and said "no, I don't think this is a good idea" By now she had gently placed hand on the top of the tent, my cock twitched, I managed a weak no but as Sonia slid the zip down and looked up at me I closed my eyes pretending to consent. Sonia undid my buckle and button and gently lowered my trousers and my shorts at the same time, my dick was semi erect from standing around so long got pulled down a little and then sprang out in one go. Sonia fell backwards, wide eyed " oh my god "she said "is that for real", she leaned forward and touched nervously as one touching a dangerous snake. Her touch was like electric shock and cock was fully erect at over 8 ½ inches long and 3 inch girth veins throbbing. Sonia putting both hands onto my dick and started to stroke it , she could not take her eyes of it like a rabbit fixed by the stare of a snake. Finally she put her warm wet lips onto the knob and made it glisten, then with a sucking action somehow she managed to open her mouth wide enough to take at least half of it in, she seemed to be choking but somehow she got used to it and started to slide up and down on it with her lips. I could not help it but let out a sigh of pleasure, this made her smile and gave her more confidence to go deeper with faster strokes, she was really good. "we must put you off everything you did tonight" I said smiling "what else did you two do?" Sonia was now enjoying herself, "well he played with me" she said shyly. "Like this" I said massaging her tits, Sonia moaned and looked a little startled I do not think she expected to enjoy it so much , "He also played with me down there" she said going bright red with embarasement. I slowing edged to the sofa with Sonia stuck on the end of cock like a hooked fish , I sat down with Sonia leaning over my legs with her tits rubbing against my thighs. Sonia was on her knees and l slowly parted her legs and softly put my hand to her young almost hairless pussy, Sonia arched lifting her pussy and going almost all the way down on my dick as she felt my hand touch her soaking pussy. All the boy had managed to do was frustrate and excite Sonia for her uncle to come along and enjoy her, and boy was I enjoying her. For a seventeen year old virgin Sonia knew how to suck . I inserted a finger into her crack, it was tight but the fluids allowed me to insert it almost all the way. Her body had gone rigid but after a couple of stroke she was pushing back onto my finger, within 2 minutes Sonia was shaking to her 1st orgasm, she was going crazy with my cock and pushed her head all the way done and I shot my load straight down her throut, Sonia started to choke and cough but managed to swallow most of it. "Well I really learnt my lesson" she said smiling but still looking at my now semi erect big tool. "Was there anything else you did?" I asked. She looked shocked and scared " there is no way he put it inside me", she said obviously she knew what I meant and was terrified of the size of my big cock. "no, but I think he slapped your pussy on the outside with it" I said. "yeah but I don't understand " said Sonia looking worried "there is no way I am going to let you put that monster inside me" "You will understand, the lesson is not complete, I promise I will not do anything you do not want me to." I said . Sonia finally agreed to lie on the sofa, I climbed on next to her and started to slowly finger her, Sonia was now really enjoy the 1 finger so Inserted 1 more finger she went rigid for a few strokes but relaxed and started to enjoy it then I inserted 1 more finger, this took Sonia quite a while before she was pushing onto my hand instead of a away. I could tell Sonia was building to another orgasm, I slowing started to suck her tits, Sonia was really starting to moan. Just as Sonia was peaking I pulled my fingers out and stopped sucking, Sonia was breathing really hard "please finish it" she pleaded in my ear. I slowing climbed on top, even now Sonia started to move away begging me not to, I promised I would not do anything she did not want. Gently I started to rub my now fully erect cock against the dripping wet lips of her pussy, Sonia shivered and kept muttering "please don't put it in" repeatedly. I started to gently tap the cock against her soaking wet pussy, slowly she stopped pulling away and eventually started to push towards my cock, Sonia had now stopped talking and breathing very heavy almost panting and biting her lower lip. "oh my god help me I am going to explode, do something" she gasped desperately. "I could put it in 1 inch, I think that might help" I whispered. Even before I finished she was nodding head looking wide eyed and trying to pull me in. As I pushed, I could feel her pussy lips stretched open wide to take my cock head, Sonia screamed and for a second tried to pull back. I stopped with just an inch in her, we lay still, Sonia's body was totally rigid she was panting "You bastard you're going to split me in two" "just relax" I said " I am not going to give you more than you ask for" I started to rock gently allowing the juices to do their job Sonia stopped pulling , she had closed her eyes and started to enjoy it. "give me a little more " she said I pushed further in with each push each time Sonia had had enough she would start pulling back and I would start stroking back and forward. Once I had about 3 inches in I started to stroke it faster and although Sonia wanted more in, I would not go further in. Sonia was soon getting desperate for more in, she had put her hands on my bum and started to try and pull me in. "Please put in, Please put more in" she was begging . By building the anticipation I knew going through the hymen and taking her cherry was going to much easier. Just as Sonia was again begging for more I lifted myself up and rammed it in to the hilt, my balls slapped against her little round bum, Sonia let out a loud scream and tried too late to push me off. I just collapsed on top of her leaving cock throbbing inside her. As the pain subsided Sonia stopped screaming and started to cry, after a few moments I started to slowly rock 1 inch back and forward very slowly, initially Sonia struggled to stop me from moving but as if someone started to release the air out of a balloon the tension from her melted away. Although her pussy was very tight it felt red hot and wet, I started to make bigger strokes, Sonia had stopped crying and started to breath heavily again and soon she was amazingly pushing into me . Sonia started to arch and moan under me as we both increased the speed and penetration. Just as Sonia rocked and shook to an orgasm, the phone began to ring, I carried on finishing Sonia but could not concentrate and pulled my dick out with a plop noise and ran over and answered the phone. It was my wife angry with me , I angrily and honestly replied that she had just stopped me from coming. Sonia started to giggle and came over and started to stroke my throbbing erect cock, she looked sympatheticly, knelt down in front of me and started to suck , my wife was still complaining on the phone but I could not hear a word she was saying, my cock was aching to explode, I just managed to say I am coming and put my hand over the phone before shooting my load all over Sonia. Sonia licked what she could and rubbed the rest into her breasts. When I put the phone to my ears again my wife was still complaining, I told her I spilt a drink and was helping Sonia clean it up. By now it was nearly 11.00pm and my wife said I should come in the morning now. With Sonia's help I did just that, we fucked all night and I turned up at my brothers next morning totally exhausted.
