Mistress Valentina and her friend had an issue with how insensitive to their plight this guy was. They needed his help but he did not want to help them. In fact, it was like he was laughing at their misery. They did not want that to happen or to continue and that is why they chose to cruelly ballbust him. They made sure that it was as painful as it needed to be and that is when he changed and acted as they needed him to.
