Huge ballkicks

The handcuffed, naked slave watches as Mistress Nikki approaches him, wearing her patent leather trousers and her huge boots. She whispers him something and in the next minute her knee slams hard into his crotch. All the wind is knocked out of the slave's lungs, then comes the next kick, this time with her boots.
