Mistress Xu had a new slave and she wanted to teach him about pain. Not the one he had heard about, but rather, the one she would inflict on him if he messed with her. So she dominated and degraded her for him to make sure that he would never mess with her. She pinched his nipples, she spat into his mouth, she kicked his balls, she made him lick her feet and she made him drink her urine.
Goddess Xia knew that her lover had an insatiable appetite for domination. The mistress did not feel like doing it today but her girl was in the mood and she had to do something. She felt like doing something crazy so as to make her not want that anymore so she got her to lick her feet and her socks before she trampled her and even got her to drink her pee. But instead of turning her off, it was the best domination she had ever had and she was super turned on and had multiple orgasms as they fucked.
