Mistress Lea did not want a slave who was a pervert. She wanted to teach him a lesson so that he would never do that again. The mistress saw no better way than to crush his nuts and she had a special too to it. His dick was squeezed and as he cried, she squeezed a little more. When she let him go, she was satisfied he would never be perverted again.
Mistress Luna is a vengeful person and this guy came to find that out the hard way. He had conned her some money and all he did was ask her about it once. He did not give it to her so she used her ball torture cbt fetish to torture him and to get him to give it to her. She revenged on him and hers was cruel and deeply painful.
Mistress Luna values her time and she was thus pissed when he wasted her time. She took it personally and she had to do something crazy to him. He learned his lesson as she ballbusted him and made sure it was the sort of pain that he had never felt before. He cried and begged her for mercy but she did not show him any. She even made him pay for her wasted time.
Mistress Luna did not want to keep up with her partner's verbal abuse. She wanted him to tame his tongue and she was tired of him promising to do it but never doing anything about it. So she helped him do it by using her heels to trample his dick as well as crushing his balls. The pain he felt was unforgettable and it helped him never do it again.
