The room echoes with the sound of flesh meeting flesh, as the mistress' powerful legs deliver swift, brutal kicks to her sub's vulnerable groin. He squirms, he begs, but she's unyielding, her eyes gleaming with sadistic pleasure. "You will learn to worship my feet," she growls, "and in doing so, you will find your true purpose." She grinds her heel into his balls, eliciting a pained howl, yet she's not done yet. She wants him to crawl, to beg, to completely submit to her dominance. And he will, for she lives for the surrender in his screams.
