I arrived home the other day and couldn’t see anyone in sight. As I approached my step father’s bedroom, I over heard him and his wife having an argument. My step mom wanted to fuck but he was too tired to give her some dick. AS he went to s***p, she headed to the restroom to start masturbating. I continued to spy on her as she masturbated in the bathroom. Eventually, I got a little carried away and went inside the bathroom. She caught me right away. Instead of getting mad, she was glad that I was there and she quickly went on her knees and started sucking me off right then and there. Soon after, we took things over to my bedroom. There, I got a chance to penetrate her pussy and eventually even stick my cock in her ass. I stretched her asshole further than it ever had stretched before. After I properly fucked her ass, I glazed her tits with my cum.
