My Sister Jean

Jean 23 is not a party girl, but likes to dress like she is and can't afford the new clothes on her wages. I'm no party guy and rarely date as women don't see me as desirable partner or something similar. I'm 5'6 balding and wear glasses, but have a great job and earn good money. I'm Fred 29 eldest of 3, with Jean as the youngest and brother David 26 is in the Navy and overseas at the moment. Our father was also in Navy and died 7 years ago in a training accident. Our mother Carolyn has remarried and we rarely see her at all now. So when Jean wants something she comes to me, Jean is 5'3" and slim also wears glasses and works at supermarket. She didn't go to university like her brothers, anyway she wanted some new style of boots and they were far too expensive for her to buy. So she came to me, I usually hire hookers for sex. But since the pandemic started have kept it my pants so to speak. Jean also a problem with rental as one of the girls had already moved out and the other was talking about doing the same. Jean couldn't afford the rent by herself, but her first concern was getting the boots as that what really mattered to her. Several hundred dollars for boot didn't seem to me to be a wise buy and I said so and on finding out about her problem with her living arrangement proved I was right. Jean said she crash a friends place for a short if had to move out. I had recently bought my own house as an investment and place to live, 3 bedrooms and 2 bathrooms. So I was setup with my own living place, a chance comment from Jean got me thinking. She said as a female all she had to do to a bed was spread her legs. My mind went into overdrive and I thought to myself, she would fuck for a place to sleep. So she would probably fuck to get the boots as well, so I asked her are you willing to fuck to get those boots. Shocked by my question at first she was silence and I could see she was thinking it over. So I added if your really that willing, maybe you could move in with me and give regular sex for the boots and as payment for a place to stay. Still quiet, I was about say just teasing you. When she said okay I will let you fuck me for the boots and a place to stay. How about a fuck now I asked, pushing my luck to the limit. Okay she answered and started to undress, we had sex and as I didn't enough cash on hand. I drove now to the much wanted boots and helped move all her stuff into my place. We have been living together since last October and I get a fuck at least once a week and sometimes more. Especially when there something she wants, I'm able try any thing I want with her and have cracked her ass. She was anal virgin till I cracked it. But there was this dress she really wanted. I don't hurt her, I take it easy and make sure she enjoys our lovemaking also. I went on holidays and she came along and we had great time together. She takes precautions and I don't and have started thinking of her having a child for me. But as yet haven't asked her, I've seen stories of relatives having healthy children and that got me thinking.
