This guy was horny and mistress Nica wanted to dominate and humiliate him. He thought that she would be his equal but she was not and she could not even think of having sex with him. So she had him undress and then ordered him to lick her high heel boots as well as endure her ballbusting. The girl enjoyed torturing him and she knew he would never do what he had done.
Mistress Nica wanted her slave to learn how well to lick socks and when she noticed he did not do it as well as she wanted, she crushed his nuts to send a message that he had to obey her instructions and follow them to the letter. The pain from her ball crushing made him do what she asked. She reinforced the punishment by trampling him with the help of her friend mistress Aurora.
