Take a spanking.

"Bend over and touch your toes," you tell her. "Don't move. Head up so everyone can see your face. I want you to meet people's eyes."

"You'll pay for this," she promises as you approach her. She's very flexible, able to touch her toes easily, and her slim, trim, nubile brown bottom juts jauntily into the air as she bends over, projecting her posterior in your direction. You can see a hint of her pubic hair and her pussy lips between her legs. "I swear it by my ancestors. I'll have my **** for this day. See if I don't."

You run a hand possessively over her beautiful bottom, pinching and fondling, even slipping a finger in between her legs to test her wetness. She squawks and squirms, but she can't escape. "Somehow," you tell her, "I don't think I will. Now I want you to count these out loud."

"Count what?"

SMACK.

"One."

SMACK.

"Oww! Two! That hurts, you brute!"

SMACK.

"Three! Vengeance! Ow! I swear it!"

"Stop talking about vengeance," you tell her, "and start talking about how you're a wicked, filthy little creature who deserves to have your bottom spanked in front of everyone. In your own words, of course."

SMACK.

"Four! Owwww! I'm a dirty, naughty, wicked trollop who's getting the proper public spanking she deserves! Everyone ought to come and see me get my naked bum smacked like the little tart I am!"

SMACK.

"Five! Ow!"

You could keep doing this for a while. At the end, though, you'll have to think about what else you could have her do.
