Lady Naomi and her friend were interested in some cruel and painful slave humiliation. That is why they settled on caging this guy's cock and he could not believe what he was made to do. He was tricked to disregard the obvious and that is why he had to eat his own cum. She told him that he was lucky not to be eating other people's cum. The slave understood.
Lady Naomi knew that this slave had a weakness for sexy asses like hers. And since she wanted to punish and torture him, she had him wear a dick lock and then she took off her clothes and she teased him. He was turned on but he could not get the cock lock off. And it hurt him as his dick had nowhere to expand to as he got an erection.
Lady Naomi despised this guy and she felt that the best thing to do to him was to humiliate him. So she did not hesitate to do it and she made sure that he was as humiliated and as degraded as she could manage to. She did it by using her chastity femdom. He was made to wear a chastity device and then she teased him and watched as his expanding dick hurt him as it squeezed again the dick lock.
Lady Naomi could tell this debtor was not about to pay her back as he had overstayed with her debt. She had to find alternative means to get the guy to pay his debt and she used chastity femdom to do it. She made him wear a cock lock and since his dick was caged, he could not do anything. He had to beg her to open it and she did it after he had paid her and she had messed with him a little bit.
