Write the following into a story. My mom and sister are hot, they are both very well-endowed and like to walk around the house in sexy lingerie. I on the other hand like to walk around the house naked, letting my massive shlong swing around freely, my mom and sister seemed to enjoy the view. Both of them liked to sit in my lap when they had the chance and wiggle theirs butts against my penis. One day my mom and sister were doing yoga in the living room when they asked me to join them, they told me to stand behind them and pull their hips into me. It wasn't lost on me that I was acutely just humping them, I knew they had to feel my huge dick.
