Every. As you know I was having an affair with my aunt that is my mom’s brother’s wife, now we got into trouble as my another aunt that is my mom’s sister got to know about us. This story is about how she humiliated and used me.Coming to the story, a little flashback, I and my aunt were having romantic time when my another aunt gave a shock by looking us, after that we came back home and were in tension of what to do, as my uncle used to come by evening, I left their place by consoling my aunt that I. And with that she pulled her hip down as far as she could without letting my cock slide out, and then drove them upwards, slamming herself into me.I was pumping furiously, her cunt softly grabbing my cock, rubbing it, not tight , but not loose, more than enough to keep a firm grasp on my member.My brain was on fire. Every single motion I made prompted me to fuck faster, both my hands on her asscheeks, pulling her warmth ever closer. Our lips met and she chewed on my bottom lip, before sticking. This unknowingly gave me a view up her skirt. With her legs positioned as they were, I was able to see that she was wearing no panties. The pale skin of her pussy was just visible at the edge of the slit in her skirt. She stayed in that position for a short time before shifting in her seat again to take away the wonderful view that I had.I was not really surprised about her choice of undergarments or lack thereof, because she frequently would leave her bra and panties off knowing how much it.
