My Sister's Plaything

I'm Robert 35 single successful in career and work from my home, I've never been a ladies man and rarely date. I had paid for all the sex I had until late last year. Then my youngest sibling Linda then 23 came to stay with me, having failed at university and not wanting to return home for some manual job in one of the local mills. She decided to try her luck in the city, soon she discovered it wasn't going to be easy here also. Linda decided she would find a man and marry and be a housewife, but she soon discovered that unless he is rich or in a great paying job. She would still have to work and finding the right man wasn't going to be easy either. In the new year and hadn't had any luck in either finding a good job or a husband. She got a little depressed, she had been keeping my home clean and doing the cooking and washing and I paid her for it so she had some money. Then one the postman had a package for me and it had to be signed for. I was out at a meeting and after she had signed for it, the postman said to have a good day Mrs. M thinking she was my wife. Linda didn't correct him and he headed off on his round. She later told me the locals thought that she and I were married, probably because we were always together. I then had a work-related dinner to attend and Linda came along with me and again some people assumed we were married due to the same surname on the name tags. I had a bit to drink and Linda had a bit also and on getting home and I said I was going to bed and she replied I'll join you. I thought she was joking with me and smiled at her, but she got into my bed with me and we both went to sleep. I got up early in the morning and went to the toilet and getting back into bed woke her up and she cuddled up to me. Then I felt her hand feeling my cock and on getting it out of my pants she started to stroke it. It was soon hard and she asked me if I was interested in having sex as she was very horny. I said you're my sister, so I'm on the pill and nobody will ever know but us. Still stroking my cock and I agreed and we had sex and again in the morning. This was the start of her sleeping with me every night. Sex between us became a regular thing and then she forgot her pills and got pregnant. She took me to a pawn shop and we bought wedding rings and she is wearing al the time now. All test on the baby was okay and only our mother Karen knows I'm the father.
