My aunt became my lover

I'm Bruce 30 single and work with computers and didn't have much of a love life. Last year during the pandemic I worked from home mostly and my aunt Fiona 44 divorced no children my mother's youngest sibling lost her job and rental apartment. With me being the only relative in the same city, she came to stay with me at mother's suggestion. Nothing happen for a week or so, but while cleaning up somethings a couple of business cards fell out of a pile of stuff. Both the business card were for hookers I had hired and they had left their cards for me. On seeing the cards Fiona didn't say anything and gave me the cards. I on seeing the cards I then knew my secret was out and I was afraid everybody in the family would find out I hired hookers. But how to explain there being in my place I was at a loss and kept quiet. Fiona didn't anything at the time and so I decided to await the fallout of my secret's discovery. The next day Fiona finally asked me why I used hookers and I said I don't do well with girls and I getting horny and a hooker is better than my hand and asked her not to tell the family. She said she wouldn't tell anyone about it as I'd been very kind in having her stay with me. Later on she again came to me and told that I shouldn't worry her knowing and she knows how it's to be horny and not getting any satisfaction. Then she asked how was I coping with the lockdown and I answered by hand. Fiona said we should help each other out in these trying times and said when I got horny she would help me out. I thought she was offering to masturbate me and then she said she could use a fucking at times as well as anybody else. With that my cock went hard and I decided to push my luck as it were and asked her if she would fuck with me. She nodded and we went to my bed and fucked and ever since that day she sleeps with me and we fuck regularly since. She has another job, but we have stayed together. I don't know how long it will last, but I'm making the most of it as long as it lasts.
