A lonely, caged cock twitches with anticipation as a man, denied release, reaches for a thick, curved sound rod. His chastity device clanks against the cold metal as he spreads his legs, guiding the tip to his eager urethra. He pushes, his breath hitching as it slides in, his prostate singing with each inch. The sound rod fills him completely, his balls heavy with unspent cum, as he grinds against the cage, seeking relief in the exquisite, agonizing torture.
