Unlace Gudrun's corset.

The laces holding the armoured corset on are not flimsy thread but strong, oiled, well-worn military grade twine, lashed by powerful fingers into unbreakably tight knots. You can't get them untied and it takes quite a lot of sawing with somebody's pocket knife before you're able to cut the ropes, but once you do the whole thing comes apart with ease. When time starts up the corset peels off Gudrun's body into several separate pieces, landing with soft thuds in the straw, revealing the facts that Gudrun's bra is also green silk and that her breasts are even bigger than anyone imagined. She gasps and covers her tits, briefly stunned, giving the crowd time to grab the corset pieces and spirit them away into the crowd as souvenirs.

"Wow. Not your lucky day, huh?"

"So I face sorcery." Gudrun's voice is full of scorn. She rises to her full height, cutting a magnificent figure in green bra and panties, her washboard abs and strong, muscular thighs on display to an appreciative audience of scoundrels and blackguards. Her two long rust-coloured pigtails hang halfway down her naked back. "Do you think I am a fool? My breeches I could believe, but armour does not simply unfasten itself. You must take me for some naive tavern slut, to have her skirt blown up and knickers disintegrated by a hedge-wizard's prankish charm."

"Well, yeah. I mean, you're in your underwear, aren't you?"

"I've faced worse. You wizards are all the same, you know. The first thing you can think to do upon learning a hint of the mystic arts is to unclasp some poor strumpet's bra from across the room, or relocate some innocent shepherd girl from her bathing-pool to a crowded market square. All the knowledge of the universe at your fingertips, and all you can think of to do is vent your basest impulses! And you speak to me of justice? Are you not ashamed, boy?"

"Hm. No."

"But you do not deny the charges. Cast aside your spells and fight me like a man, or prove yourself a coward in front of all these fine, upstanding citizens. Such is my challenge to you! Dare you accept it?"
