"You need to be locked in chastity for life," she commands, her voice a mix of authority and arousal. The room is filled with the clinking of metal as she secures the cold, unyielding device around his eager cock. He watches, entranced, as she fastens the lock, the key disappearing into her cleavage. She smirks, "You'll never touch yourself again without my permission." He nods, his breath hitching as she trails a finger along the outline of his imprisoned penis. She stands, towering over him, "And now, let's see how you handle some... encouragement." She picks up a small, vibrator, pressing it against his balls, making him squirm in his bonds.
