My Sister in Law

Written by , on 2018-06-17, genre straight

I Donald 34 married with 3 children and a gorgeous wife Alice 32 a lawyer. I'm an architect with my own firm. My brother Robert 37 is also a lawyer and travels a lot and his wife Karen 34 is also a gorgeous woman. They have 1 child 5 and Karen wants another, Robert has tried to get Karen pregnant and he hasn't done so by the time Karen got fed up. She told me Robert was not really trying and all their sex was quickies and and not as often as she thought was needed to succeed. Karen works in the same building as me as a accountant. We have lunch together sometimes with Alice, one day 4 months ago Karen asked me if I could donate her some sperm to her to get her pregnant. Robert was to busy to do the job of impregnating her, so she was going try using sperm donated by me hopfully. She asked and begged, I was taken aback by the request and just said I would think it over. A week later she asked If I had thought it over. I had hoped that she would have given up on the idea. I said I wanted to ask Alice what she thought and hadn't had a chance as yet. Karen didn't anyone else knowing about her plan and asked If I could keep just between the two of us. I wasn't to keen on that and said I don't keep secrets from her. Karen started to cry and I don't like women crying due to the trouble my mother had with cancer when I was 8 and the pain she suffered before she recovered. So I agreed and we had to work out a way of getting the sperm to her at the right time. After a couple of tries. Karen suggested straight sex as something always delayed the transfer and she reckons a lot of the sperm died before she could use them. Robert was away and Alice was on a big case. So Karen said How you and I getting a room or something at lunch and you give the sperm straight into me. I said I'm not sure about a room, how about my spare office I use for storage there's an old leather bench seat there and we wouldn't have leave the building. Alright she said Tomorrow lunchtime you can service me. So next day we met at my office and left together and instead of going to get lunch we went to my spare office and we had sex. The next day same thing and for a total of 5 days. We repeated it the following week and than waited a month to see if if she missed her period. She did and a few after that, it was confirmed she was pregnant. Robert and her had sex during this time, but she is sure that it was me that done deed. Now that she pregnant, Alice has started talking about another baby to even up the children with another boy. I told her it is not certain that she have a boy and with twins both sides of the family she may have twins this time. She then asked me Do I want another child. I said I do, I was only tell you what could happen. So we started trying 2 weeks ago.
