Madame Marissa found out that there were certain fetishes that she had not tried. She had to try them and she did it by humiliating this guy. He did not have a say in the matter. The mistress had all the say and all he had to do was follow what she wanted or else things would be thick for him. That is what he did and he followed all her instructions including licking her spit and doing other cruel and crazy fetishes for her fun.
