Bound and helpless, the slave's cock throbs in its steel cage, aching for release. His femdom, clad in leather and lace, teases him with her delicate touch, running her nails along the metal. She grips his chastity device, giving it a cruel squeeze that draws a pained moan. 'You'll never come again,' she whispers, her breath hot on his ear. She begins to stroke his cock through the cage, her touch maddeningly light. He bucks his hips, desperate for more friction, but she pulls away, laughing. 'Not today, pet.'
