I found myself in a beautiful position. My father had left our family. It was my Mom, my sister Gwen and myself having to carry on. I heard my Mom crying one day. I comforted her by having sex with her. My eighteen year old sister Gwen saw us doing it. Gwen was horny and I ended up fucking her as well. It wasn't a bad position for a twenty year old guy to find himself in.
I tried to keep my mother from finding out I was fucking both of them. The time had come, I wanted both of them together in bed with me. I woke up one morning. I didn't bother putting any clothes on. I walked out into the kitchen to find my Mom and sister there.
"You might as well know, I'm fucking both of you."
My Mom said, "we know."
My jaw almost dropped. My sister said that Mom and she had discussed it some time ago.
"We want to have a threesome with you Justin," she said.
We went back to my mother's big bed. Both women stripped out of their clothes. It was quite a contrast. My Mom was a full figured woman. My sister had small breasts and hardly any hips. We all got onto the bed together. I was in for a surprise that morning. Both my mother and sister started to work on my bone.
Both women were licking up and down my shaft. They soon took turns sucking on the head of my dick. I had to control myself from unloading there on the bed. It didn't take long before I was stiff. I made both women get on the edge of the bed. Their legs were draped over the edge.
