Mistress Nadia is not the kind of person to mess with as this guy came to find out. He was a bully and he wanted to scare her and get her to give her money and do her favors but she was not that kind of person. She rolled him in a carpet and she trampled the shit out of him. She stomped and jumped on him as he begged for mercy promising never to do it again.
When his Mistress arrived home, he knew that this evening would turn to a painful torture. He heard it when her high heels stomped strong on the floor on her way to him. And - in fact - she wants to trample his balls just to calm down after work. So she stands on his dick with her soles and her heels, before she starts trampling and crushing his penis and balls with her sharp heels. He can't help himself but gets a boner, and this is much more painful!
It's a quite hard lesson for Miss Katarina's slave, and also kinda humiliating: She drew the outlines of a body on a cardboard and laid it on him, just to trample and stomp on the covered pieces. But though the pain is really hard, cause she only can guess where his bodyparts REALLY are. You remember: she only drew outlines! Her slave suffers from her sharp heels that dig into his nuts and trample his whole manhood, his face and throat and nearly every other part of his body! Afterwards she tramples on his chubby chest without the cardboard in between them.
This cheeky schoolgirl accumulates all her anger in her feet. She tramples her slave under her hard, flat soles. You already hear him whine under her weight, but that gives her only more motivation to let him suffer. So she starts crushing his head with the same power she crushed his chest, without regard. When he struggles from pain, she kicks his legs back in position - she's not finished yet!
