The slave's balls are a delicate instrument in the symphony of pain and pleasure orchestrated by his mistress. She kicks them gently, sending waves of sensation through his body. Then, she squeezes, her strong fingers enveloping his testicles, applying just the right amount of pressure to make him gasp. She's a master of her craft, her touch a dance between torment and ecstasy. She knows his limits, but she pushes him, her voice a whip cracking in the air, "Take it, slave. Take it all."
