This mistress was just from a session with her money slaves and she was happy. They had complemented how great and sexy she looked and showered her with money. The mistresses loved it because it was not even pay day for her when all of them gave her a certain amount of money. This was specific to that day and it was a surprise as she did not expect it.
Goddess Mel was not happy with this paypig. He had not been making remittances and she was tired of his excuses. The money she made from slaves were her source of livelihood and she had to make sure she gave his share. So she humiliated him by trampling him and teasing him at the same time. She gave him an incentive to give and a punishment at the same time.
