This guy needed to be ballbusted because of his nonsense and lady Scarlet engineered that to happen. The mistress went ahead to let her friends know what the guy had done and why he had to be punished. So the three of them ballbusted him and there was nothing he could do about it as they enjoyed torturing him for their own fun. He cried but that did not make them stop.
Lady Scarlet had some enemies she needed to teach a lesson but as she was trying to find out which method to use in doing so, she had to make sure that the method was effective. And that is why she chose to use ballbusting but before she did, she had to test it on someone to find out its efficacy. And so she settled on her slave and she crushed his nuts with a string and with her high heels.
This married man wanted to have a threesome with lady Scarlet and her friend mistress Gaia. They were offended by what he said and they chose to punish him. The mistresses teased him and got him to think that they were interested in what he wanted but it turned out it was just a set up. They stripped him naked and crushed his nuts to teach him to remain faithful to his wife.
