In porn there are two main types of photo shoots, and one is called “pretty girls” where the model/performer poses by herself all sexy and glamorous. Today's photoshoot is the other kind, “sex stills”. That’s where the performers actually fuck and pose for still images. If you’re on set you can kind of predict how the sex scene will go as the sex still are shot. You can see if the girl is into it, if they have chemistry, if they fit together. In this case Paulina James seems to like it. She likes the dick.
