This guy was unreliable and mistress Man and mistress Qiao had to punish him for it. They did not want to deal with his unreliability anymore and so they made him pay by trampling him, making him lick their asses and worship them as well as turned him into a pee slave. He had to drink their urine before they were done with him. He did his best to avoid being unreliable as he knew what would happen.
