In the dimly lit dungeon, a mistress takes her new slave through his first chastity training. She secures the steel cage around his erect cock, the cold metal a harsh reminder of his new status. She leads him around on a leash, his every movement restricted by the device. He's made to kneel, to beg, to perform degrading tasks, all while his cock strains against its cruel confinement. The mistress, ever watchful, delights in his discomfort, knowing that each moment in chastity is another step in his transformation into her perfect, obedient slave.
