In a BDSM dungeon, a bound sub, his cock confined in a cruel chastity device, is the target of a relentless femdom onslaught. His mistress, clad in leather and latex, tantalizes him with her body, running her hands along his cock, making him beg for release. She denies him, time and again, pushing him to his limits, his balls aching with unspent seed. In the final, brutal round, she edges him repeatedly, leaving him a sobbing, desperate wreck, his chastity device dripping with his frustrated lust.
