Madame Marissa did not like the kind of food her slave prepared for her. She wanted him to make better food so she told him to use cooking magazines and recipe websites. To give him motivation, she humiliated him by using her feet. She trampled him using her bare feet and made sure he was in the kind of pain he had never been in before. He learned how to cook great meals as a result.
Miss Serena is not your average mistress. She likes to do things her own way and does not like anything done any other way especially in her house. Her new slave did not know that so he tried a different system which he thought was better. But he met her wrath when she found things were not done her way. She crushed and trampled her slave using her bare feet to make him do what she wanted.
These mistresses wanted something this guy had. But he had refused to give it to them and they were pissed. They were tired of asking for it so they took it by force. The mistresses used their bare feet to crush him and by the time they were done, he gave them what they wanted. They crushed his balls and he did what they wanted because of the amount of pain he felt.
Goddess Candy and Emily caught this guy eavesdropping on them and they had to punish him for his behavior. They laid a trap for him and he took it. The mistresses went ahead and tortured him by trampling him. They trampled him at the same time and they did it from head to toe. His balls were also fair game to them so he had to endure that they did to him.
