Mistress Quimera for the first time, is decided to put an end to the relationship with her slave, so to castrate her slave, crushing his balls and his cock using her feet. Her goal is to make the slave powerless, to destroy his balls because she believes he doesn't deserve to have it. She steps on his balls a lot, steps on his dick until he starts to agonize, and she doesn't stop until he's totally destroyed and crushed. At the end she orders the slave to get on his knees and kiss her feet, licking all the dirt off her feet and thanking him.
