Slap a curse on their butts

*Slap*

"Ow!"

*Slap*

"Ow!"

*Slap*

"OW!"

After the third spank to her little posterior, you allow the human girl up from off your knee. She tries her best to examine her buttock, and the symbol you left there. It's a crude image of a naked girl covering her goodies and screaming, captioned "I was Stripped by Someone Smarter than Me!"

"Did you mark my butt?" she says, glowering at you.

"Yeah," you say. "It's an adhesive curse, designed for those of us with marginal skill in the magical arts. Ain't that fun?"

"What did you curse me with?" she asks.

"It'll be more fun if you found out for yourself."

She looks like she wants to press the question, but the sound of a boy remarking on the size of her breasts reminds her that the public attention she received has not ebbed since her spanking ended. Her embarrassment wins out and she crosses her hands over her chest, scrambling to find her clothing. Retrieving her gown from where you left it, she squirms into it, only to have it dissolve into nothing. The townspeople laugh heartily as she gives a yelp and doubles up over her nude body.

"That's right!" you say. "As long as that mark remains on you, you're going to remain naked!"

The human girl's eyes go from checking on her nipples to exchanging a glance with her cohorts, both of whom have been fiercely encouraged to wait patiently for their own spankings. The dark elf and the orc both go wide around the eyes.

While the human girl screams to the heavens, her comrades in arms gather up their boobs and take off running in a **** attempt to avoid the same fate.
