This mistress knew this guy had a thing for her. She flirted with him and invited him back to her place once she was convinced he was hooked. She undressed and teased him and got him where she wanted. She made him believe that she got super turned on whenever he drank her pee and the guy drank her pee eagerly without knowing that he was being pranked and humiliated.
This guy knew he had no chance with his mistress. When she made him drink her pee, she took advantage and licked her pussy and clit too and got her horny. It led to wild sex
