Nucklefuck captures the tantalizing moment when a husband's curiosity gets the better of him. His wife, fast asleep, is unaware of his wandering hand as it sneaks beneath the covers, seeking her warmth. He traces her slit, feeling her dampness, and tentatively slips a finger inside. She wriggles, her breath hitching as she begins to wake, catching him in the act. But instead of anger, she's turned on, ready to take charge and teach him a lesson in dominance.
