My Sister Helen

Brief history I've always done very well at school and very poorly in relationships with women. At 33 I was at the top you could say, except I was single with no love life and living alone in my own 3 bedroom 2 bath house. I've a great car (electric), last year during the lockdown my sister Helen 28 party girl and didn't go to university lost her job and lost her cheap rented apartment. Our parents have both retired to the coast and I as her only sibling had to help her. No problem there I was willing to help, but got a little uncomfortable for me after she moved in. As she wore very revealing clothes walking around the house. Leaving nothing to my imagination you could say, I had to masturbate more often after she moved in. As there was a lockdown she couldn't go out and find a job or have fun as she put it. I was able to work from home and ordered in everything we need including female products for Helen. Then the lockdown ended and we stayed together and she got some spot work and I still worked from home. Being driven around in my car, Helen really liked my car and wanted to drive it. I did allow her to drive it and it only increased her her desire to get a car for herself. But she soon realized she never afford a car and certainly not a electric one like mine. Back in January she caught me masturbating, I was on my bed and thought she was out at spot work working. She had finished and had come home and came into my room to ask what I wanted for dinner. So she caught me and with a big grin on her face asked me what I wanted for dinner then she left. She made some joking remarks for a few days and then she dropped it. I noticed a week later she seemed to be thinking a great deal about something and that surprised me as she usually acted on impulse rather than thought. But in the middle of February on a Saturday she asked could we talk , I said yes what about. She answered you, me what about I asked. You don't have a social life and never go anywhere she replied, so that's the way my life is I responded. Boring and I think I can help you she added. It might be boring to you, but I'm use to it and I'm happy I replied. What about sex she then asked, I simply said you seen how I cope with that. Your missing out on a great deal she replied, I simply replied what you can't get you learn you miss if you don't think about it. Well I know I can get you the sex your missing out on and would be willing to help you if you got me a car she said. What type of car and how would you get me sex as payment for the car I asked not really thinking much about as a offer more of a joke at my expense. Electric car a base model and I'll provide all the sexual training and when I think your ready help you find someone as well she replied. I was shocked and silence for a time, finally I asked so you would train and fuck me your own brother. Yes why not, I have casual sex all the time and your a man and I'm a female the only problems with incest is pregnancies and rape. I'm willing and on the pill so no rape and no babies either she added. I could of said no straight away, but I must say I was interested in her offer and so just said I'll think about it and left at that. Quickly returning to my home office, I started thinking on her offer. Putting it into context as a business offer. I buy her a car and she teaches me about women and lets me fuck her and would also help me find a woman for myself. My head didn't make the decision, my cock did by go hard. I could easily afford the car and even if she doesn't find me a woman as a partner. I might get enough confidence to hire one every now and then. So I went and found Helen and told her if her offer was still on I accepted and asked how and when she wanted to start. Yes the offer is open and if you've nothing urgent on now we can start now she replied. I'm free now I answered and she got up took my hand and led me to my bed. She got me to get naked as did she and she got us into a 69 position with her on top and I done as she said and after she mounted me and we fucked for the first time. We fucked 3 more times that afternoon and night and the next day we both went car shopping, base model wasn't available and would have to be ordered in. But a better model was available and so I got it for her. She was delighted to have her own car and better than she had asked for and she told me she would make me very happy. We headed home and on getting home she started undressing straight away, I first had to ring a electrician to get another charging station installed at my home as we now had 2 electric cars to charge. Helen then fucked my brains out the rest of the day and night, sex was anytime I wanted or she wanted which was the more likely way we had sex. A week later the new charging station installed, Helen also got a fulltime job and was working at the same place as me. The number of fucks slipped a bit, but were always very enjoyable. Helen said I was great in bed and it was time we found me a lover/partner and started looking around for someone suitable for me. Then back at the end of July, she found Jane 31 who also works at the same place as us. Jane is the bookish type and quiet by nature Helen's description to me. Helen started to get closer to Jane and see if she could become good friends with Jane and then getting us together. It was easy to become friends with Jane as she was like me and kept to herself even at work. But getting Jane to be a lover of mine, was going to be tricky Hellen thought at first. But in late August, Helen herself got Jane into bed and had a sexual romp with her. It was a very raining Saturday afternoon and Helen was over at Jane's apartment and a bit bored. Helen started mucking about with Jane to break up the boredom and it led to them kissing at first and then in bed together licking, fingering and sucking each other. The next day when Helen got home from Jane's place she told me she had bedded Jane. Good for you I said and I looked a bit confused on how that helped me bed Jane. Helen said now I've bedded her I can move her towards at least a threesome including you to you fucking her by yourself. Things started to move quickly or quicker than I thought they would. Helen bedded Jane more and more and when Janes lease was up, convinced her to move in with her and me. Jane had met a few times and at least she was comfortable around me enough to talk to me, even when alone together. Helen still enjoyed the sex between us and wasn't in any hurry to stop us fucking and wasn't looking for another lover either. At the end of September on Jane's birthday Helen and Jane got drunk, Helen was just tipsy rather than drunk and she got Jane naked on my bed and a short time later I walked into my room finding them both naked and going for it. Helen told me to fuck Jane as it was her birthday and I did and after fucked Helen as well. They both stayed in my bed that night and I was able to fuck Jane 3 times in all and Helen just the once. Neither me nor Helen had thought of Jane being on the pill or anything else and she wasn't. But it didn't stop the sex the next day, while Jane was still not fully with it we kept fucking her and I fucked Helen as well. That night Jane was worried she might get pregnant and wasn't concerned that I had taken advantage of her when she was drunk. I told her I was there for her regardless of whether or not if she got pregnant. I said wanted her to be my girlfriend and she just smiled at me. The sex continued and we didn't take any care and last week Jane was confirmed as pregnant and to Helen's shock her also. After sometime thinking and the 3 of us talking, Helen has decided to have the baby if everything is fine with it. So with no future of having a girlfriend or ever getting a woman pregnant, I have now a girlfriend soon to be wife and a sister also pregnant. Who stills fucks me and sleeps with my girlfriend. Nobody outside our little group know I'm the father of Helen's baby.
