In the dimly lit dungeon, a stern mistress welcomes her new submissive. She commands him to strip, revealing his eager, erect cock. With a cruel smile, she produces a chastity device, running her fingers along the cold metal. "This," she says, "will keep you in line." She fits the cage around his throbbing member, securing it tight. He winces at the initial discomfort, but she only smirks, "You'll get used to it." She then commands him to kneel, attaching a leash to his collar. His humiliation is complete as she leads him around like a pet, ready for her every command.
