Mistress Mia B wanted to give a class on trampling. So she took a video of one of her trampling sessions and posted it online. She wore her high heels and then got on top of her slave and trampled him painfully. She trampled his back with her high heels and took care to make sure that her full weight was felt. The slave screamed and since she was not punishing him, she stopped.
Stellina fell out with her boyfriend over how he wasted their money. She was not happy that he blew it all on gambling. She had to do something drastic about it. Something that would speak to him the way words could not. She had tried to talk to him but it did not work. So she trampled him in the chest and balls with her high heels and inflicted excruciating pain on him. That did the trick.
