Kneeling before his mistress, the slave's balls ache in anticipation. She grabs his chin, forcing him to maintain eye contact as she slowly, deliberately, and viciously grinds her heel into his balls. His cries of pain echo through the room, but she silences him with a slap, reminding him of his place. She continues her torture, alternating between crushing his balls and stroking his erection, ensuring he feels every ounce of her power.
