The mistress had to slap his face and when she was done with that, she did the same to his ass. The mistress was not in a hurry to finish it so it went on longer than he expected it to.
Mistress Dula felt that this guy was full of negativity and she did not like that. She wanted to humiliate him and she did it in a way he had never experienced before.
