Lady Despina did not want a lazy slave in her house. That is why she chose to punish him. She did so with the help of her friend, who wanted to learn how to punish people who messed with her. The two of them ganged up against the poor guy. They trampled him while he was naked, and they made sure that every part of his body was in pain.
Lady Despina did not like how dishonest this guy was. She was pissed off at him for being that way and she had to make sure that he changed his ways. That is why she went out of her way to use her great femdom fetish to dominate him. She ballbusted him with the help of her friend and the two of them enjoyed making him regret what he had done.
