Seeding my Sister

I love sex and have a great career and earn big rewards as a result and own my apartment. My sister wasn't doing that well and lost her job and needed my help, which I was willing to provide. That was December 2019 and she moved in with me and was trying to find another job. Plenty of interviews, no job offers followed and then the pandemic/lockdown hit. I was able to work from home and so I wasn't worried about my future, except it would stop my sex life for a while. As the lockdown dragged on, I got really horny and had started watching my old neighbor across the street undressing. That was when I decided I needed sex really badly, but the only female I had access too, was my sister. She is good looking and only real problem was she was my sister. But my cock took over my thinking and I finally asked her for sex. That was a shock to her at the time and she said no. But that wasn't the end of it, she had no money and depended on me for everything. But then by pure chance while in lockdown, I got promoted. I was next in line and expected to move up in about 2 years, but the former holder of the position got Covid and passed away. He was a lifelong heavy smoker and Covid was the last straw, the position also came with a PA and the current PA was also retiring. So, I was told and so not only a promotion, but job vacancy as well. But I didn't tell my sister she could have the job if she fucked me. She knew of the vacancy and my promotion and no requests for sex were made by me as a result. I was hoping for a quicker end for the lockdown, that's when the vacancy would be filled. My sister told me that she was also having to satisfy herself and said if I got condoms, we could assist each other. I ordered in some with the week delivery we were getting. We started sex and were sleeping together every night after we started fucking. A month after we had started fucking the lockdown finally finished. My sister applied thru the HR department; I helped her fill out what was needed. She got on the short list, but the other withdrew and my sister became my PA. We had started back dating after the lockdown, it was slow going as people weren't moving about like before the pandemic. So, sex with my sister restarted and continues today. She like to fuck almost as much as I do and we're quite happy as of now.
