In the kitchen, he fucked his mother-in-law’s ass

I found my aunt cleaning the house in her underwear; you can imagine what went through my mind when I saw her almost naked body. When she saw me, she got on all fours on the sofa, offering me her huge ass. I took out my dick and, without thinking, put it in her ass.
We didn’t say a word; there was no need. But I spent a good amount of time fucking her ass until I finally came. Of course, my uncle neither knows nor will know anything about this.
