In a dimly lit room, a muscular jock finds himself at the mercy of a stern mistress. She runs her fingers over his bulging cock, then cruelly slides a chastity cage onto it, locking it tight. He whimpers, trying to hide his humiliation. She laughs, a sound like cold steel, and starts a relentless tease. She strokes his caged cock, pinches his nipples, slaps his ass, all while denying him the orgasm he so desperately craves. She loves his suffering, feeding off his humiliation, making him her plaything.
