You want her terrified and submissive

"I think you're lying," you say coldly. "I think there's more that you're not telling me."

"No! That's all! Oh God that's all I know! All I heard! Please! You've got to believe me!" she whimpers frantically, her hands clutching at your pants as she stares up at your in frantic appeal, her face a mask of terror. "I'll follow them tonight! I'll watch for them to leave and follow them and find out where they go and tell you! I promise! I'll be your spy! I'll be your good girl spy!"

"I think you're a lying whore," you say, making your voice implacable and laden with doom.

"I'm telling the truth! Oh God you've got to believe me!" she begs. "Don't hurt me! Don't! Oh God Don't!" she pleads desperately, her face crumpled and tear-stained in panic. You sneer at her, stepping back out of her reach and sitting in a chair. You free your cock, pulling it's rampant length out and watching her eyes widen in submissive fear.

"Crawl to me like the animal you are," you order. "Crawl like a bitch."

Without hesitation she drops to all fours and starts to crawl across the floor to you, her eyes never leaving your face and cock. Her rump is raised as she crawls and you enjoy the sight of her submission, your cock throbbing as you watch.

When she gets close enough you lift one foot and stop her, pressing your shoe against her chin. She looks at you in confusion, obviously expecting to be ordered to suck your cock and trembling slightly in anticipation of punishment.

"Lick it. Lick my shoe you fucking animal," you tell her, your voice full of cold disdain.
