The main crux of this finished four years ago.
I met a girl in a pub and we hit it off straight away. She was with a large group of people celebrating someones birthday. She didn't quite fit with the rest of the group as she was slightly younger. Then when I suggested going somewhere quieter she jumped at the suggestion. I took her to a very quiet carpark and I took her virginity in the back seat of my car. I saw her for a few more times and the relationship was going nowhere. I decided to tell her straight out that it was over. I knocked on the front door to be greeted by the girl that was the center of the party. It was her sister. To shorten this account I ended up in bed with the sister and married her a year later.
Many years later still, the wife's sister had married, had kids, got divorced, had more kids...... You get the picture. She had really let herself go. I definitely married the right one. Anyway the sisters oldest girl, Tisha, would spend time with my wife rather than her own mother. I looked at the three of them once and in profile they were exactly the same size and shape.
I had taken a new job at work managing a group of over forty men. It was hard work , but well paid as it was night work. As the manager of this group my hours were flexible as long as they completed their work and to a good standard. To help the transition on to night work I had redecorated the spare room and had triple thickness curtains made to block out any light so I could sleep. Also it left my wife undisturbed so she could get her sleep.
I was now ten months into this night working. I had got in at four a.m. It was a dark wet and gloomy night. The work had gone well and I had read my boss's latest reports that I had the best team that month and was in for a bonus. I was tired and just had a drink and gone to the spare room and got into bed. I was dozing and thought I was dreaming that my wife was in bed with me. I reached out and felt her hot body and stroked my hand over her boobs and held on to one. Later in the dream her hand was stroking my cock and balls. It felt good in my dream. I rolled towards her and stroked my hand down her body and between her legs. It was hot and damp. Her hand was slowly wanking my erection. Then I was in deep sleep.
It felt quite a long time later that I stirred and discovered that my hand was between her legs and she did have hold of my cock. My wife had done this a few times since I started the night working, it was usually when she had the following day off. I moved my hand and stroked her fanny and she groaned and her hand resumed the slow wanking action from my dream. Then I had two fingers in her and was finger fucking her to her first of several climaxes. She panted and groaned through each one. I was in need for more than a wank as it had been nearly three weeks since we had managed to find the time to make love.
I climbed between her legs. They wrapped around me as I positioned myself and slowly sank my cock into her pussy. It was a short sweet fuck that probably lasted no more than four minutes before we came together. We lay panting for a while. I needed the loo and a drink, so I went to the toilet and then downstairs to the fridge. The clock said ten o'clock, I had six hours sleep which is often all I need. I had a swig of orange and as I closed the door I noticed a note on the fridge. It read:-
Bill ..... Tisha is staying over tonight so come to our bed with me when you get in. Love ......
Tisha is my wife's sister's daughter, my niece! It dawned on me I had just screwed my niece. I went back to the spare room and put the light on and sure enough there lay Tisha completely naked.
"Can you do that again uncle T," she asked, "your very good at it." My niece was asking me to fuck her again. I knew it was wrong and the first time was a genuine mistake, but a second time would be cheating on my wife. Before I had a chance to say anything Trisha was on her knees sucking my limp cock. It wasn't limp for long. As they say men think with their cocks. Well mine was screaming at me to fuck the daylights out of this nineteen year old girl that was less than half of my forty two years of age. My head was saying this is wrong on so any levels. She is less than half my age, she is my niece, my wife's sisters little girl. Then there was my cock saying, she's not so little and she is giving great head and you have fucked her once already. Besides you have over seven hours till wifey gets home and you don't get much pussy these days.
Needless to say the cock won. I pulled her up and turned her around and bent her over leaning on the bed and slammed my rock hard cock balls deep back into her wet fanny. She squealed at the suddenness of total penetration, but that soon changed to groans as I plowed her willing fanny, I cupped her tits to give additional leverage as I slammed into her. I felt her climax and her juices were running down both our legs. I just kept on thrusting getting closer to my own climax.
A fleeting thought crossed my mind, Contraception, then it subsided when another thought reminded me that I had already washed her insides with my sperm and a second wave would not have increased the risk by much.
Then it happened, her fanny got tighter and she squealed again as we both reached our climax and I washed her insides some more. We collapsed on the bed panting and gulping air. Then Tisha said, "Wait till I tell mum that your still a good fuck and she married the wrong man." I was horrified and told her that she couldn't tell anyone what had just happened, especially my wife and her sister. "Just joking," she said, "But for an oldie you are a damn good fuck, far better than any of my boyfriends," she told me.
Tisha was not at work and was currently getting dole money, so she had most days to do what she pleased. We dressed and had some breakfast and sat at the table talking.
" Does auntie M always get that good a fucking, " she asked. I joked back, sometimes better. "Can we do it again," she asked. I had her promise that she would never tell anyone, before we went back to bed and had a far more sedate slow fuck in the spoon position where I kissed and sucked my own nieces tits, before releasing a third load of sperm into her pussy. Fortunately Tisha told me she was on the pill.
I gave Tisha a spare key and over the following two years there was hardly a week went by that she didn't sneak into my bed once my wife had gone to work and we would fuck our brains out. Then the night work came to an end, as did our regular fucks. I saw her a few more times before she went off with someone else and had six kids by three different men.
My wife knew nothing of my affair, but was pleased that the night shifts had ended as I took our sex life to another level and took my new found sexual relief with my wife. She says that If my sexual energy wains she will have me back on night shifts. If she only knew where that energy came from.
