Ball draining neighbor

I live in an apartment building and work at a local factory and also works shifts. So, my social life isn't that great. Luckily for me, I've a neighbor 54 who works as a librarian and is divorced or never married she hasn't said I haven't asked. I found out she likes sex in every way it seems. She gives great head and loves her ass fucked more than her vagina and I found out due to the pandemic. Both caught in our apartments during lockdowns and started to talk and hang out together and then dining together and then fucking. After the lockdown I was back to my normal work shifts and she hers. But we have continued fucking every chance we get.
