Princess Serena took this guy's keys. She did not want him to go home. She wanted him to stay with her and do some naughty things. He thought she wanted to screw him but she had other ideas. She wanted him to do naughty things for her enjoyment. She made him lick her ass and she also had him jerk off to her instructions which were humiliating and degrading to him.
Princess Serena caught her slave watching porn and she was not happy with him. She was disappointed and she had to teach him a lesson. She did this by trampling on him painfully. First of all she tied him up to avoid any resistance then she taped his mouth to avoid him making noise that would attract the neighbors. Then she had a field day humiliating her slave using her feet.
Princess Serena is not an easy to please mistress as her slave came to find out. She likes things done to perfection and her instructions followed to the letter. She had this loser lick her feet and suck her toes and whenever he deviated from what she wanted, she humiliated him and tortured him as punishment. He learned to follow what she wanted to the letter to avoid the resultant punishment.
