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.
