Give Vanessa a taste of her own medicine.

You look the sadistic witch up and down. She's a little smug, you think. After stripping those bandits and tormenting Evellyn, she's beginning to get a little full of herself. Maybe it's time you took her down a peg or two. Plus, she's very beautiful, and you can't resist the impulse to see what's going on under those clothes. But you have to be careful. You don't want to fall prey to her magic. You might end up humiliated instead. That wouldn't do.

The first thing you do is go outside to fetch some anti-wizard powder from an apothecary you know. The glittery rainbow dust will negate all Vanessa's powers, at least for an hour or two. You don't know exactly what she's capable of, and you don't want her turning the tables on you. You unfasten the sorceress' red, fur-lined jacket, fold it neatly and place it on the table next to Evellyn's clothes. Then you pull her red silk dress up and off her head, nodding with satisfaction as her lacy red panties come into view. The sorceress is deliciously curvy, with rounded hips and full breasts concealed in her equally red, equally lacy bra. Cascades of dark hair frame her beautiful, flirtatiously smiling face.

You put the dress next to the jacket, take a step back and are about to let time start up again when you remember the anti-wizard powder. Wouldn't do to forget that. You cover her liberally with the stuff, making sure she sparkles with rainbow dust from head to foot. Then you drop back into time. Vanessa's smile slowly fades as she realises what's happened. She draws her legs up in front of her, clearly a little embarrassed but not wanting to give you the satisfaction of a squeal.

"Well," she says crossly. "I expected this moment would come sooner or later. But you’re about to regret it, rogue. It’s high time for black tentacles!"

You watch her hands move, and grin as the spell dissolves like wet paper on her fingertips. She looks down, and for the first time realises what she's covered with. "Anti-wizard dust? This stuff costs a hundred gold a pinch!"

"Not to me."

"Oh, come on. I thought we were friends. Do you really think being caught in my underwear bothers me, anyway? I've faced worse. I’ve done worse while drunk!”

She sounds confident, but you're not fooled. You heard her voice catch when she talked about being caught in her underwear. You look her up and down, watching her try not to squirm as she realises you're blatantly ogling her boobs. She's still putting on a confident front, but you think you can crack that facade.

"Hey, Vanessa," you say. "Have you ever been completely publicly humiliated before?"

"Um... what?"

"Remember what you did to those bandits?" you say. "Tying them up stark naked in the public square? I was wondering if you'd ever been on the receiving end of anything like that."

"I... we're friends," said Vanessa. She's beginning to look very nervous, and a little bit annoyed. "You wouldn't do anything like that, right? Besides, I'd get my ****."

"How? You don't have any magic."

"I'm telling you, I don't get humiliated. You can't do that to me. I'm a powerful sorceress."
