I'm going to have a great time while my father-in-law is away, let's get down and dirty with some hot sex

My father-in-law is heading out on a trip and my wife\'s asked me to take care of her mom until he gets back. While I was out, she sneaked into my room and got down on her knees, unzipping my pants and taking out my throbbing cock. She\'s a hot, young blonde with a big ass that\'s begging for a rough fuck.
