In a dimly lit dungeon, you find yourself at the mercy of a dominant woman, her eyes gleaming with anticipation. She teases you, running her hands along your bare chest, before presenting a gleaming metal chastity device. "This," she purrs, "will keep that monstrous cock of yours under control." She slides the cool metal around your shaft, locking it into place. You groan, your cock throbbing against the confinement, as she laughs softly, "You'll beg for release, but only when I allow it."
