A devoted male slave reaches his breaking point after 20 days in a cruel chastity cage, his balls aching with pent-up semen. His dominant mistress, a sadistic MILF, teases him mercilessly with a powerful prostate vibrator, pushing him to the brink of madness. She milks his prostate, coaxing out a massive, ruined orgasm, as he's forced to watch his thick cum fountain out of his locked cock cage, leaving him a quivering, humiliated mess.
