Mistress Dula and her friends wanted to torture this guy and the best way they knew how was to use their dominant tickling fetish to do it. They held on to him even as they had tied him up and they tickled him. It was painful as they continued to do it and he cried and begged them to stop but they did not. Even peeing on himself did not make them stop.
Mistress Gaia knew that this guy could not handle her tickling. So she made a bet with him that if he endured it without begging her to stop, she would give him some money. He agreed. So she tied him up and then she did it. He tried his best but he could not hold on any longer. He even peed himself in the process and he lost the bet.
