My Choice

I'm the youngest of 4 and have 2 brothers and a sister. My career is doing very well and I'm the only one not married and have no intention of marrying so far. At 35 I've my own apartment with a live-in housekeeper 58 divorced. Who happens to be my sister (37) mother-in-law MIL, that's why she became my housekeeper in 2020 in a roundabout way. In February 2020 she needed a place to live and my sister and her husband unable to take her in. Asked me to provide short term housing, but due to the pandemic. It became longer term than first thought, as she done the cooking, cleaning and laundry. It didn't concern me all that much. But as the lockdown dragged on, I got more and more horny and started to masturbate myself. I also liked being massaged and unable to get a massage because of the lockdown. I started getting really annoyed by the length of the lockdown, my annoyance was clearly visible to my sister's MIL. So, she asked what was wrong and I told I missed getting regular massages. She said she was qualified to give massages but could give a rubdown if I wanted. I thought for a minute or two and decided why not give it a try. Her rubdown was good I enjoyed it, and it became part of our normal routine. Of course, the massages I got before the lockdown had a sexy woman doing them and she always got me off by hand. So, the rubdown soon became both back and front and so during one of those rubdowns I got a hard-on. To my surprise it didn't faze her at all, and she just got my hard cock out of my shorts and got me off. That also became part of the rubdown and then I put my hand under her dress and started feeling her up as she did the rubdown. No complaint from her I started fingering her the next time and no complaint again. The very next rubdown she told me strip naked and I did, she also stripped naked. The next time after that she started to masturbate me but stopped as I inserted my finger into her pussy. Instead, she got on top of me and inserted my cock into her and rode me until I came inside her and that was the start us fucking regularly. When the lockdown ended, she stayed living with me and also sleeping with me, unless I brought woman home or stayed out with a woman. Still not interested marriage and enjoying my new lifestyle, best of all I don't pay her for anything she does for me, as she financially well off herself. The sex is for our mutual benefit. I suppose I'm her stepson-in-law.
