This guy had pissed mistress Saida off and she wanted to humiliate him for her own fun. That is why she chose to humiliate him and she wanted it to be a painless affair. So the mistress turned him on wit her seductiveness and her big tits. Then she had him jerk off and when he came, she made him eat his own cum. It was humiliating but he had to do it.
Mistress Sophia knew that this guy was naughty and she used her naughtiness to get business from him. She had studied him and she made sure she appeared hot and sexy. And she did not give any hint that she knew him or she was interested in anything from him. And he approached her and she showed him her naughty and kinky side even going as far as making him cum and getting him to eat his own cum. He was into her and as he got to know more about her, she landed the deal effortlessly.
Goddess Nika wanted these guys to eat their own cum. And she gave them instructions to that effect. But instead of them doing everything as she continued giving instructions, she gave them the instructions and when she was done, she asked them to implement them. So they had to remember what she told them as they jerked off and when they were done, they ate their own cum. She told them next time they would each other's cum.
