Passing the time

I've been in isolation for a while to keep healthy and avoid the coronavirus. I'm Alex 32 single and able to work from home. I lived alone in my own 3 bedroom house, once the coronavirus started spreading I decided to stay home and isolate myself. I received a call from my sister Rachel 28 single and lived on the other side of the city to me. She had lost her job and couldn't afford her rent and wanted to know if she could stay with me. I told her, she was most welcome and so she moved in with me. This is where I tell you that we are both gorgeous looking people with really sexy bodies. We're average at best and are both in and out of relationships. Shorty after Rachel arrived and having stocked up on everything we could want, we settled into the new routine in our lives. Nothing really exciting, I would do my work and watch movies or play games and when I needed too I masturbated. Rachel done similar things, including trying to get an online job to earn some money. Over the next weeks nothing much happened, boredom set in and one day I got so bored and watching Rachel bending over looking thru a stack of dvds. I asked her would she like to join me in my bed for sex to pass the time. Not expecting a reply and to my great surprise she said okay let's fuck. So we went to my bed and fucked, it soon became a regular routine in our day. Rachel started walking around the house almost naked and I soon followed her example. By the time we were able stop isolating, Rachel and me were sleeping together every night and still even now. Rachel is looking for work and is going to stay with me even after she gets a new job. We like the sex, it a lot easier than dating. If I want sex I just ask Rachel and she agrees or doesn't agree to have sex. Same for Rachel she asks me and we mostly fuck.
