In a dimly lit dungeon, a mistress, clad in leather and latex, begins her slave's rigorous training. She commands him to present his balls, then viciously stomps them, her spiked heels sinking into his tender flesh. The slave cries out, but the mistress is relentless, her kicks precise and powerful. She revels in his discomfort, ordering him to thank her for each strike. Between the brutal impacts, she torments him with CBT, twisting and pinching his balls, her touch as cruel as her words.
