The dude wanted to rent a porn video but unfortunately the box was empty.
He asked the clerk about the movie and it turned out that the video was missing. Luckily, the nasty babe, who worked at the video rentals shop, knew what she had to do in order to serve the client and to make him return in the future. She simply asked him if he would like to experience that movie in real life. Sure, the dude was intrigued and very soon he was shagging a tight pussy of the seductive clerk.
And, as you can guess, the lucky stallion forgot about the missing video totally.
