Using my Sister

I'm Gordon 32 and due to some very good luck and some of my own personal knowledge, I'm now very well off financially. Was still doing rather poorly in my love life, but that changed when Daniel suddenly died of the corona virus. He believed all the bullshit and didn't get vaccinated, I got vaccinated as soon as I was able too. My sister Joyce 28 was married to Daniel and like him didn't get vaccinated either and also got ill. But she recovered and now widowed and in a debt up to her eyeballs. Turning to me for help as our parents and Daniel's also believed the bull and paid the price. As her only relative, I had to help her. Our parents always rented and didn't leave much behind after their deaths. I did have my own home and Joyce and her daughter Christine 4 came to live with me. With no real skills, Joyce could only get low paid work. Daniel was a only child and hadn't been highly skilled either before he passed away. After paying off all her debts, Joyce was stone broke and owed me big time. $13,753 was what I shelled out to get Joyce debt free, I knew she would never be able to pay me back. But she was my sister and I could afford it, also it was nice not being alone all the time as well. I work from home now, it started in the lockdown last year and I preferred to keep doing after the lockdown was over. Only going into the offices, when I really have too. Joyce got several short term jobs and Christine was able stay with me while Joyce was working. I took them both out to have meals and see movies and the zoo animals, just to break up the boredom mainly. On 1 of our trips we went to the local beach for a swim and Joyce wore a bikini that really didn't leave anything to my imagination. That was the first time I looked at Joyce with sexual thoughts. But I didn't try anything there or later at home. But I now saw Joyce sexually rather then as my kid sister like before. Then I decided I should add both Joyce and Christine to my health insurance, just in case. Not that they were sick or anything and Joyce never had a health insurance before or had our parents ever had it themselves. I was sitting on a chair in my back yard having a beer on a Saturday afternoon and Joyce came out and asked me what I what. Meaning for dinner that evening and I said a woman, she smiled and replied hotdogs it is and went back inside. That evening Christine had went to bed and I was thinking of turning in myself. When Joyce asked could we talk, okay I said what's up. Joyce said she needed some things and so did Christine also and she wanted to know If I would lend her the money. What things I asked, underwear and clothes especially for Christine as she was growing out of everything she had. Okay we can go shopping on Monday and you can get what you want I answered. But Joyce added she would help me out for helping them out, I was a bit confused. So I asked How, I will sleep with you and at least you will get some satisfaction she answered. I was shocked at first and just looked at her and she added I'm also a bit horny and it will give us both satisfaction. My shock had passed and my now hard cock thought a great idea. That was the first night we slept together and it soon became the normal thing for us to sleep together. Now 8 months later and Joyce is pregnant (about 6 months) to me, she changed her surname back to mine and to everyone else outside our family group she my wife. Christine doesn't know anything different and has referred to me as daddy a couple of times. Joyce wears our mother's wedding rings and all test show the baby girl is healthy and we plan to call her Barbara after our mother.
