In a dimly lit room, a woman, a mistress of her domain, holds a small, intricate key, her eyes gleaming with anticipation. Her captive, a man bound and eager, awaits her command. She approaches him, the key dangling tantalizingly from her fingers, a cruel smile playing on her lips. "Once I turn this key," she purrs, "your cock stays locked forever." She teases him, running the key along his chest, his abs, his thighs, avoiding his aching cock. He's a pawn in her game of control, and she's the master, ready to make every moment count.
