This slave was too pretentious for these mistresses to tolerate. That is why they chose to hard trample him so that he dropped his pretense. The mistresses did it with their shoes and it was painful. As they were having fun at his expense, the mistresses even danced while on top of him. As for being cheeky, they had clothes which showed their tits so he saw them and was conflicted between the pain he felt while being trampled and the pleasure he had on seeing their boobs.
