Sister Gwen

Long story short version. Gwen 28 single overweight low self esteem, lost her job and came to live with me. I'm Ewan 31 single skinny, balding and you guessed it not great at dating women. What I lack in my love life I made up for in my work life, doing very well and able to buy my own house at 28, no loan cash. I don't own a car don't need one, public transport is great and getting parking anywhere close to my workplace would be a nightmare. So Gwen arrived on a Saturday and I show her her room and let her settle in. During the next week we didn't interact that much. Mainly I go to work early, Gwen looked for work and didn't find any available work she could do. This was how it was for about a month. Then I had to take my annual holidays as it was required by the company not to store them up. Usually I stayed at home, I didn't pick periods that suited me I took what was left after everyone else had picked their holiday dates. So I was lucky this as a sci fi convention was on and it was only in the next state. So I decided to go and see it and also decided to Gwen along. After seeing the sci fi convention, I had booked a couple extra days to look at the sites museums and art galleries that sort of thing. One art show there was a lot of nudity in the displays and some were very suggestive. I don't know whether I was aroused by the art display, but after we had dinner and a few drinks and returned to our hotel room. I got a hard-on when Gwen over in front me and I made a move on her. She didn't react in anyway at first, but as I started to kiss her she started to respond by kissing me back. If she had tried to stop me, I would have continued and we ended up fucking and fucked again later and then slept together and I fucked her again next morning. I had gotten sex from her and so I continued to make moves on her the res of the day and that night. fucking her again that morning we checked out and returned home. On our arrival at my home. I had just put down my luggage and kissed Gwen and took her to my bed and fucked her again. After I asked her to move into my room, Gwen did as I wanted. No fuss at all, so I started fucking anytime I wanted and she let me. Then several months later our mother Margaret 59 widow arrived, I knew she coming as her apartment building in our old home had been sold and she had decide to move to us. Margaret is an older version of Gwen and when she asked how we were, Gwen said I'm pregnant. This was a shock to Margaret a shock to me also, Margaret asked next who was the father and got the reply Ewan is. I suddenly realized Gwen didn't date and wouldn't be on the pill or anything else. Margaret asked pregnant are you was told about 5 months. About the same time as the sci fi convention, well you will have get the baby tested Margaret said. Gwen said he already had and the baby was healthy no problems at all. Turning to me Margaret asked what are you going do now, I replied keep going as before and look after Gwen. Good that's the best answer Margaret replied. I was bit still in shock, but one good came from Margaret knowing I'm fucking my sister. Gwen sleeps with me every night still and I still get to fuck her. After the birth of our Daughter April in June this year and Gwen was still in hospital with little April for another day or so. Margaret and I had a few drinks to celebrate and she got drunk and I fucked her twice that night and again in morning. The second fuck the night before she was totally out to it when I fucked her. But was willing in the morning to be fucked again by me. She also provided most of the sex until Gwen had recovered from having April. But Margaret shares our bed almost every night, Gwen wears Margaret's wedding rings and everybody thinks I married her.
