Mistress Gaia felt that her slave needed to learn proper manners from her. She had thought he would self correct himself but so far, he had not been doing it. She was not impressed by his conduct and she had to do something. After a little research, she settled on hot ballbusting as she wanted to punish him once and never have to do it again. So she got the helpd of her friend and the two mistresses crushed his nuts using heels and they slapped and kicked him brutally.
