All Thanks to the Coronavirus

I'm Neil 34 single and youngest of 3 and haven't had much success with women. All the sex I had I had to pay for. I'm short 5'3" skinny and have male pattern baldness and wear glasses, I do have my own home and due to the coronavirus my sister Kimberly 39 single and eldest of my siblings came to stay with me. Arthur 37 my brother lives and works interstate close to our parents with his family. Kimberly was stood down because of the coronavirus causing the company to close as to the lockdown being imposed. Kimberly is strong willed person and hadn't found a man to suit her and so was single. Kimberly mainly moved in with because her apartment building where she lived was a place you would probably have a greater chance of catching the virus. With my home with just 2 people there was less risk. Nothing special happen at first, but I noticed she was getting restless. So I asked what was wrong, she said her clock was ticking and I said shut it off or put it in another room. Not that clock she said my body clock and if I don't have a child within the next few years, I won't be able too. Well you still have time I replied, not if this lockdown keeps going she added. Why don't you asked your boyfriend to move in with you here I said. What boyfriend, she replied. Oh, I thought you must have had someone in mind to father your child I said. Kimberly then told me that she had intended meeting someone and having a sexual relationship and getting pregnant by them and then raising the child by herself. She aid I can't see myself marrying and had even thought about I V F, but had dismissed it for having to much regulations connected to it. I left it at that and went on with own things. A few days later I saw Kimberly looking as if she was deep in thought and didn't bother her. Later that same day she came to me and asked would be able to help her out, certainly I said what do you want me to do. Get me pregnant was her answer, I think my jaw hit the floor. I'm your brother I answered, so I've done some checking and brother and sister can have healthy families together if there isn't a history incest in the family line. I know there isn't in our family line and as far I can go back and we would be the first in our family she said. Why me I asked, we're cooped up together here for God knows how long and with my clock ticking I should start as soon as I can She answered. Kimberly is 5'5" and of a fuller figure, not overweight. I started to think it over and my cock had made up it's mind and went hard as a rock. So I said if your really sure I'm willing to help, good we can start tonight was her reply. She joined me in my bed and after a awkward start got into having sex and again in the morning and everyday for a week we fucked. Then there was news that the lockdown would end in 3 days if the case numbers stayed low. I thought no more sex then, but Kimberly had made up her mind I would be the father of her child and that was that. So we kept fucking and after the lockdown was lifted did she start trying the home test kits. Nothing at first, but jus as I thought it wasn't going to happen she got a positive result and then another, only then did see her doctor and it was confirmed. We now have a healthy baby called Gregory after our father and she has told the family she I V F. Nobody has question it and I still get the odd fuck now and then, she sold her apartment as she think my house with its garden would better to raise Gregory. The family have told Kimberly she should help me find a wife, she said she would try. I've asked her if she wants another child and she said she is thinking about it.
