I got my Neighbor Pregnant

Quick background. I'm Frances 22 and live in the old family home alone my parents retired to the coast 2 years ago. Last year during the lockdown, I was hanging out with my neighbors Keith 49 and Rebecca 39, they already had 2 children 21 and 19 who away at university. After the lockdown finished Keith went back to travelling for his work and was gone for weeks at a time. Rebecca and me would still hangout together a bit, when I wasn't at work. On the start of another lockdown, Keith was caught interstate and unable to get back before the travel stopped. He stayed with his brother for the lockdown, so it was just me and Rebecca. Nothing happen at first, but later on we started playing cards and drinking to pass the time. Still nothing happened, but just before the lockdown finished. There was a fierce storm and with lots of lightning and thunder claps all around and the power going out. It was scary for both of us at first as the we knew of the storm was very loud crack of thunder over head. We were playing cards and drinking when the storm started. The card game when the lights went off, but the drinking increased a bit. With storm still raging outside, Rebecca told me I better stay with there overnight due the storm. So we kept drinking and then started mucking about and ended fucking. It was just a fuck, as a way of relaxing to the fury of the storm outside. But it was enough to get Rebecca pregnant, she hadn't been on the pill due to lockdown and Keith being away. She didn't realize that she was at risk until a few days later and then the lockdown finish. Keith returned home and everything was getting back to so called normal. The first I knew I could have made her pregnant was a week or so after Keith had got back. Keith was out getting some stuff and Rebecca told that she might be pregnant and asked me to buy her a test kit. I got her the kit and she used it and it gave a possible positive result. Not a strong result, but it was early days as they say. She done another test a week later and a strong positive showed. Two weeks and another test and she made an appointment to see her doctor. After doctor confirm her being pregnant she told Keith she was pregnant. He was happy that she was pregnant and she told me not to say anything about our one night stand. She has since had a baby girl they Catherine after Keith's mother.
