My Aunts Diary

I'm Alfred 23 single and youngest of 3, my parent George 49 and Marianne 47 are both lawyers and are away a great deal on cases. My mother younger sister April 38 also a lawyer single average build and looks. I'm the only one not to go to university in my family and I work as a mechanic. Recently I was over at April's home fixing her car as it had a shudder when started, a engine mount had broken and it caused the shuddering. I found and got a new mount and replaced straight away. But While I was working on the car April had to go out and she left the house for me to washup or use the toilet while was out. I was finished shortly after she had left and went inside and cleaned up. I was intending to lock up and go. But I saw April's diary on a table and had a quick peek. Nothing really thrilling in the diary at first, but then I discovered she wanted desperately to have a child of her own. Not in any relationship at the time and was considering donor sperm as away of getting pregnant. But she worried about getting the right sperm, as she had done a case of a couple getting an different race child from the donated sperm to what they had chosen. I put her diary back as I had found it and decided to have shower before going. I was in the shower and masturbating, when April returned and entered the bathroom to use the toilet. Catching me masturbating, she didn't anything and she quickly left to use the upstairs toilet. I was dressed when she returned downstairs and I said I was sorry for shocking her and that I only did it to keep in practice for donating sperm. She was shocked that I donated my sperm and I was lying about it just seeing what she would say about her plans to have a baby. Nothing at first, then she how many times I had donated and I lied again and replied on average once a fortnight. But there was a lot weird looking people that also donated. She asked what do you mean by weird. I said they dress weird and some of them smell really bad as well. Then I changed the subject to her car telling her it was fixed, adding if there's nothing else I'll be going. I could see her thinking and as I turn to leave, she asked me more about my sperm donating. I told her every time I donate I fill out a form about myself. What do they want to know on the form she asked, the usual stuff height, I Q and medical history. I can put down anything and they don't checked it much if at all I answered. I could tell by her expression she wasn't going to get donated sperm to get pregnant. I added I don't know about all the sperm collection places just the ones I go to. Then I turned to leave, she asked me could I stay longer and I replied I could. She got herself a wine and gave me beer, she was quiet for a little while. Then she straight out asked me would I help her get pregnant, I was shocked at first and finally asked why me. She said she had be thinking of using a sperm donation to get pregnant and after what I had told her she had changed her mind about using donated sperm. Also she didn't have a boyfriend or close unmarried male friends to ask. She knew I being her nephew made it incest, but knew from her work that children were born healthy in such relationships. I thought I would play her along a bit more and said that the donation clinics done the insertion and how would we do it. I didn't know how they did it. She thought for a short time and replied straight sex. I was shocked again at first and asked when would she want to start. During my cycles she replied and I'm in the right cycle now and we could do it straight away if your willing. I was unsure, but my cock went rock hard straight and so I agreed. Thinking nothing might happen or if she got pregnant it would make her happy. So I went with her to her bed and fucked her twice and then went home. Next morning I came down for breakfast and my mother said April had called and she had a flat tyre and wanted to know if I could fixed it for her. So after breakfast I headed over to April's home and on arrival I was met by April in her night gown and she opened it to show me she was naked. She wanted to keep trying for a baby and so we fucked again and again and that was how it was for over a week. Even after her cycle was finished we had several fucks just in case. I was at a loose end on a weekend nothing that interested me was on and my friends were away. Sitting feeling bored and seeing the neighbor in her dressing gown talking to my mother at the fence. Made me think of April and with nothing else to do I went over to see April, not expecting her to let fuck her outside her cycle. But there always a chance and on arriving I said I come to see how she was doing and I tried to kiss her. She pulled away, but then asked me had I come over for sex. I replied I hadn't come for sex, but on being close to her, I got the urge for sex with her. She said alright let's fuck, it won't hurt anyone and so I spent the day with her. April got pregnant after her next cycle and regularly lets me fuck her. She is having a daughter and all tests shows she is very healthy.
