Mistress Nica and her friend had a slave who was both lazy and badly behaved. They were not going to stomach it and had to find a way to get him to either change or get fired. He was taken to the stable where the mistresses trampled the shit out of him. They did it while he was naked and it was even more painful and more humiliating for him.
These mistresses did not like how they had been betrayed by their friend. They had to make sure it did not happen again and that is why they went out of their way to humiliate him. The mistresses tied her naked on a pallet and they trampled and dominated her while her naked boyfriend watched. He was told if he reacted he would also face the same fate as his girlfriend.
Mistress Nica wanted this guy to know who she was and so she used a body bad to immobilize him and then took advantage of that to dominate and humiliate him. She even turned him on and ruined his orgasm all for her own fun. He cried as he felt pain and as he was teased and denied but he could not do anything other than beg her for mercy.
