My Sister Martha

I'm Gerald 32 and doing very well career wise, no good at all in a love life. Meaning none at all, but that changed when my sister Martha 29 suddenly divorced last year. Her husband Terrance suddenly decided he wanted a divorce in March and Martha was caught unaware and was shocked the request for the divorce. Terrance wanted out of the marriage and gave her their house and a large cash settlement for no ongoing alimony. Martha accepted and the divorce proceeded fairly quickly, once final Martha couldn't live in the house. Too many memories and so she sold it and came to live with me, her only sibling. I was happy to have her stay with me as we always got on very well growing up. She stayed home for the first few weeks and enquired why I didn't date, I said I don't do well with women and had given up on chasing them. But I hadn't really started, but Martha decided to get me out and about. We started going out together and she soon realized I wasn't a chick magnet in any way at all. First she tried changing the way I dressed, but then realized it wasn't working. She then decided it was mental state, where I was putting out the wrong vibes (failure) as it were. Putting off women near me, she wasn't affected because was my sister. She became determined to change my vibes and to that end she joined me in my bed and started fucking me regularly. She noticed a change in me when we were out and about, but not enough for her. So she kept on fucking me and finally I got a woman bedded and pregnant. Martha got pregnant to me and after tests were done and no problems, she decided to have the child due in August. We sleep together every night still, Martha works at the same company as me now as my P A. I had gotten a promotion and an office secretary and P A. The secretary Dianne 31, Martha thought would be good for me and took it upon herself to get us together. Dianne is reserved not shy and Martha succeeded in getting Dianne into my bed. The first time was just her Martha and the second was a threesome. Dianne has now moved in with us and I'm thinking of asking her to marry me. Martha and Dianne both share my bed and Dianne know I'm the father of my sister's baby.
