The selection has been made and we begin with an interview to evaluate each girl. We test their physical endurance during the interview, and that's when I realize that we are going to focus on that for the day. Neither of them know where the pain threshold is, so that is also tested. After realizing that both are pain sluts, we have to show them that there is a line that shouldn't be crossed. I take them to that line and let them dance on it to understand that they have to know their bodies and limits.
