What you see here is a girl that knows how to tease her stud. She knows that all she has to do is flaunt her sexy body and her man will get turned on. How can this guy take all of this sexual teasing without wanting to fuck her? I really don't know how he does it, but he seems ice cold when it comes to her sexual advances. It could be that she was to be the star and was just there to soak in seeing his girlfriend get topless. He might just like showing off the very good looking chick that he's fucking. This fella gets so much pussy from his girlfriend, he's probably excited to take a break from screwing her. Most people would agree that this guy gets way more sex than they do, which probably explains why he's not all over her. It makes you wonder if he's dreaming about pounding her while she's getting nude. With all of that said, he's probably thinking about fucking her the whole time he watches as she takes off her clothes. Hopefully she at the very least swallowed his dick when they got back home. No need to worry, he probably did have fun later in the day.
