A bound straight man endures exquisite torment as his femdom mistress teases his chastity-caged cock and probes his virgin ass. Wrists secured, he's at her mercy, his prostate targeted by a relentless vibrator. She edges him mercilessly, denying him release as she explores his tight hole with a curious finger, gasps echoing in the dungeon. His body betrays him, leaking pre-cum, desperate for the forbidden orgasm she refuses to grant.
