Pandemic Love Affair

I had to isolate with my sister, we hadn't got on very well growing up. Neither of us were in any relationship prior to the lockdown and I had to move in with my sister because where I lived was damaged by fire caused by the old electrical wiring. Not much damage to the building, but all the wiring would've to be replaced. Which wasn't top of the to do list allowed during the lockdown. My sister lived in a 2-bed apartment and took me in, mainly because I could work from home and would still have a paycheck. With her having been stood down as soon as lockdown were talked about before being enforced. As the lockdown dragged on, the boredom became almost unbearable. Not that I was a great lover but had some success before the lockdown. Anyway, it turned out my sister was also bored and finally with her wearing only underwear during a rainy week and the clothes dryer not working and unable to get a repairman. I made a comment about her, she made a smart reply. We start to wrestle like when we were younger, her bra came off and I started to suck her breast. At first, she was annoyed, I kept sucking as I was enjoying doing it and it annoyed her. She stopped resisting and started responding and we ended up fucking on the carpet. Once we had fucked, we kept up the sexual relationship and still live together now and share the same bed regularly. But we still date other people and yet still to find our perfect partner. But we did move after the lockdown was over, as I bought my own house instead of renting and my sister lives with me.
