Trip her up.

You step out of the way of the gypsy's charge and stick one leg out. She trips over your leg and lands face-first in a pile of soft hay that you've thoughtfully provided to break her fall. You don't want her hurt, just blushing and bewildered. She picks herself up, spitting out straws, her beautiful bare bottom flexing, and turns to face you again. Her hands cover her modesty as best they can. Her left hides her nipples and her right conceals her sex, but she can't conceal the fact that she's naked except for her gold decorations in the middle of an appreciative audience. You look her up and down insolently, making sure she knows that you like what you see.

You see her hands moving. She's trying something.

"Sorcery it is, then," she says, feigning calm. She's clearly seething with rage and humiliation, but trying to save face by not showing emotion. "Well, warlock, it just so happens I know a few tricks myself. Ancient gypsy magic that makes the incantations of you city-dwellers look like meagre toys. We'll see how you smirk once my curse puts you under my complete control!"

You whistle. "Nice pussy, too." Hand gestures are part of the spell, which means she's not able to cover herself while she does it. People nudge each other and point as her tits and pussy come on display once more. Her face darkens.

"Take that!" she says, pointing at you. A bolt of blue fire springs from her hand, leaping directly toward your heart.
