Mistress Ava Black needed to put this guy in his place. He had been thinking that he was a free spirit and he could do whatever he wanted anytime. So the mistress removed such thinking as quickly as he had it and she made him endure pain and humiliation by being ball crushed by the mistress. He did not try to refuse as he knew what would happen in that event.
This mistress did not want anything to do with this guy. But the guy pleaded his case and being a compassionate mistress, she agreed and she teased the guy like never before. He thought they would make a sex tape together but it did not work out that way. She teased him and got him to jerk off according to her instructions. He had no alternative but to do what she told him.
