Bored home self-isolating with sister

I've been home and self-isolating due to the coronavirus, not sick and sitting playing games, watching movies and after several days got very bored. I'm usually very busy and going everywhere, staying in one place soon became annoying to me. I'm Andrew 32 single and sharing my apartment is my sister Lauren 30 war widow no children. Then last week I was bored and very frustrated, I just asked Lauren for sex as a change to our new daily routine, not expecting her to agree. But she looked at me for a moment and answered okay I'm horny and could do with a fuck. So we fucked and fucked again later on and since then she has slept me every night. We aren't worried that's it is incest as weren't hurting anyone and we're both enjoying the sex.
