You awaken in the middle of the night to the sight of a man and a woman standing over your bed. The man is handsome, with a smart vest, black slacks, and perfectly shined dress shoes. The woman is beautiful, wearing a slinky black cocktail dress and deep red lipstick.
Anticipating a struggle from you, the man pins you down while the woman covers your mouth with her hand. You don't struggle, though - the sight of two very attractive people in your bedroom isn't something you get to see very often, after all. These people are clearly dangerous, but you find yourself wanting to let them do whatever they want to you.
When they're certain you won't scream, the woman takes her hand away from your mouth and the man grips your jaw, pulling down your bottom lip with his thumb to reveal your teeth. You're not sure what they have planned until the woman holds up a pair of pliers and a knife.
"Now," the man says, his voice deep and seductive, "which one would you like her to use first? Don't worry if you can't decide. You'll get to experience both before the night is over..."
"I choose the, uh..." you stammer out, looking at the knife, then the pliers, then settling your gaze on the woman's red lips, curled up at the sides into a sly smile.
