This guy had money which mistress Iside wanted but he refused to give it to her. She had asked for a soft loan and would pay back within a week but the guy refused even though he could see it was an emergency for her. So she used nipple torture to get the money from him and she told him that since she had to force it out of him, she would not pay it back.
Mistress Iside wanted to get the money she had loaned this girl back. But instead of repaying, she always had some story. She got tired of the excuses and she had to act because she felt that the girl was taking her for granted. So she used her nipple torture fetish to dominate and degrade the girl and as she felt the pain, she knew that she had to repay. She did so the next day.
Mistress Iside is a sadist and she loves to have fun at the expense of other people. That is what she did today when she turned this guy into her human toy. She undressed him and after whipping him for a little bit, the mistress tortured his nipples and he was not only in a lot of pain, but she also had him crying and begging her to stop. His cries of pain were music to her ears.
