Perfect Sister

I'm Martin 26 and work in construction, 2 years ago I had an accident at a job site and was laid up for 8 weeks at home after 3 weeks in hospital. As I'm live a long way from most of my family, I had to rely on my only sister Ruth now 29 single plain looking good shape with thick glasses and dresses like the an old librarian. Long sleeves and high neck line dress that went past her knees. Barely any skin showing at all, she had always been a book worm. She worked from home as a secretary for different small businesses. They weren't big enough for a full time secretary and she would do any office work they need done by computer and process their mailing and such. She charged a a flat for each client of $400 a week and $50 an hour for any extra work. With 15 clients she was making a good living and worked long hours. She owed her own house and after my accident I moved in, giving up my rented apartment so she could look after me. Mom had come east for 2 weeks and help get me settled in Ruth's house. Ruth wasn't in to cooking, so mom made all of meals during her stay and put alot more in the freezer before she left. The day after mom left, I was in bed as was usual, when I got an itch that I couldn't quite reach. I tried everything I could thing of to scratch it, Ruth came in and said That she was going get lunch ready. So I asked her if she would scratch my itch, she tried to scratch it but as I was in a single against the wall she had to lean across me to get to it. By turning on my side a bit and she finally got it, her leaning across me with her tits touching me caused me to a hard on. Which I hid from her, as I didn't want her to think I was perverted. That night after we had dinner I watching TV, when Ruth came in to give a spronge bath. She opened up my PJ's top and rubbed it all over front and back, when she finished the top half she went to do the bottom half. On opening up my PJ's bottoms she was confronted with erection. She just ignored it and proceed to spronge me, on finishing she done up my PJ's and left saying you must be desperate to get horny over me. I didn't say anything, hoping that it wouldn't become a regular problem. She returned later asking if I wanted anything. I joking said "Only You". She reponded saying " Your not making fun are you, I know I'm the best looking woman. But I do have feelings and always wanted to be with a man. But haven't been that lucking". This made me feel like the jerk, idiot and a total asswipe". So I replied " I think your great and I love you dearly. I would make love to you in a heartbeat, if you would let me. But I would want to pressure you into it". Thanks was her reply as she left the room with a smile on her face. About a hour later she returned in her nighty saying that she was going to bed. So I feeling bold said " Do you want company in your bed". Waiting for her reply, but she just turned around left the room I called after her saying I didn't mean to hurt your feelings". She returned a short time later with the wheelchair saying you'll need this to get to my bed. I thought she was playing a double bluff for a moment, but she was serious and helped me into the wheelchair took me to her room. We had sex and I enjoyed a great deal. She had to do most of the work, as I was on my back. In the morning she got me my breakfast and said Thanks I won't died a old maid virgin, just an old maid. I respond " You mean weren't doing again, I was hoping to sleep with you again tonight". Well if you want was her respond we can. Now that I have recovered from injuries I'm still living and sleeping with her. Mainly because I like fucking her and I'm trying to get her pregnant as well. Her period is late and she buying a test today to see if she is pregnant. I hope so, she doesn't want me to stop seeing other women. But I'm happy with Ruth and maybe if I can find a woman who is bisexual. It's the only it could get any better.
