Her need My dream

Short history. I'm quite well off financially due to my academic success and the career that followed. Teased at school and university for being a geek/nerd I out preformed others to succeed in my chosen field and got a very good job as a result. My parents were quite gifted as well and had me when they were in their thirties. They had my sister several years later and she was a bit of a disappointment to them, as she didn't show any interest in her schooling. She scraped into university and just graduated almost at the bottom of her year. Several years later our parents passed away, leaving us fairly well off even without our own careers. My sister was a partying girl and quickly blew thru her inheritance in a few years. Then the pandemic started, her job disappeared and with no savings to support herself, she was in trouble. I hadn't touched my inheritance and didn't party at all. I was very comfortable and had no worries at all, I wasn't in any relationship and didn't think about having one either. I'd lost my virginity by paying to lose it and had since moved on as they say, not thinking about women much at all. Growing up I'd spied on our female neighbors dressing or undressing and when my sister had developed fully, I use to spy on her. Nothing had happened between us, till the pandemic caused her lifestyle to crash. No job and no place to live either, having lived paycheck to paycheck and not having a good credit rating. She had to call me for help, even with a lockdown in place, I was able to have her come and live with me thru help of my employers. Now living together and her being very bored and nothing to do, made her look at her lifestyle and she found she had no future. She also realized her career prospect were low at best. Also realized she was just being used and then dropped by her suppose boyfriends for someone else as she wasn't seen as marriage material by any of them. A plaything at best, she also knew of my lack of relationships. At first, she considered asking me for a loan to improve her life, but then realized she wouldn't loan herself money either. She noticed I was the godfather of work colleague's children as there were pictures of my godchildren. Thinking I must want a family of my own saw a slim chance of a better life. Finally, she approached me and offered to have a child or two for me in return for financial support from me. Of course I was at first shocked by her offer, but I'd dreamed many times of fucking my sister over the years. But I asked what does your offer actually mean. She said regular sex with her until I'd the child or children I wanted. I responded what's the limit of children you are offering to have for me. Her response was No limits while she could have a child for me she would. Of course she would expect to be well looked after by me, I said I would look after as long as she needed my help anyway. Her response was I know, but this way you actually get something I know you really want out of it. I thought to myself it was actually two things, children and sex with my sexy sister as I dreamt about for years. I couldn't say yes at the time, but nodded my approval and she started sleeping with me from that day onward. Six weeks later the lockdown ended, and she hadn't gotten pregnant as of then. But a month later she was pregnant, and we would've a daughter. My sister acted as my wife and especially after the birth of our daughter who was very healthy. Nobody realized our actual relationship, even my employers didn't seem to notice our close family relationship. But they are very busy and had probably already forgotten they had help her move to live with me about fifteen months before. Same surname and baby girl and so everyone assumed we were married. Now we've a son together as well born in March this year, my sister is happy just being a mother and doesn't seem to miss her old lifestyle. She talks about us as a family and wanting even more children, I'm quite willing to do my part. As children we never had a pet, our parents wouldn't us to have one. My sister got us a puppy when our daughter was one saying every child should have a pet. My life is complete as far as I'm concerned, I have two beautiful children and beautiful wife/sister what else is there to have.
