In a dimly lit dungeon, Mistress Nail, clad in gleaming latex, commands her pathetic slave to kneel. She towers over him, her towering heels threatening. She begins a slow, sadistic dance, her boots grinding into his vulnerable balls. He winces, but she demands silence, slapping his face. She kicks his crotch, again and again, each impact echoing his whimpers. His cock twitches, betraying him, and she laughs, grinding her heel into his balls until he's begging for mercy.
