I smiled, didn’t bother much, but asked her to relax. With my hands I started spreading her legs farther I spread her legs and asked mom to spread t...em further and lift them as well. She followed my commands. I hold her legs and put them on my shoulders. I brought my penis near to her pussy, adjusted the tip over her pussy and started to push it inside. It was still tight, and I thought that my dick is bigger than dad. I spread her cunt lips with one hand and hold my penis with other hand and. Her booty was tight but we were both loving it!

The neighboring booth had the light on to indicate it was occupied. I put money into the machine and the screen lit up. It couldn't have been a better scene. There was a girl fucking.
