In the dimly lit dungeon, a dominant mistress teases her caged slave with the promise of release. She orders him to masturbate, knowing full well the cruel chastity device will make it impossible. His futile efforts to pleasure himself only serve to amuse her as she watches, laughing cruelly. She then takes out her frustrations on his helpless cock, subjecting it to brutal CBT with clamps and weights, all while he's forced to beg for mercy.
