Cheat, of course.

Well, obviously you're going to cheat. You could never beat Gudrun in a fair fight, and you have no intention of letting yourself be made into a naked barmaid. Your cock would never fit under the apron.

Moving at speed, you reposition Gudrun's elbow, placing it several inches out of line so she can't get any proper leverage. When you return time to its normal speed it doesn't mater how strong she is. Her arm slips and you have her hand down instantly.

She gazes at it, and then you, in mute horror. "How... what..."

"Looks like I won. Strip."

"But..."

"Strip. Naked. Here. In this tavern. Right now."

For a moment it looks like she'll meekly accede to your request, and then her native barbarian spirit reasserts itself. "No! By Skuthi's veil, I could not have been defeated by a mere southern weakling! You must have cheated somehow! I'll pummel you until..."

Suddenly, all her armour disappears. She looks down. She's wearing nothing but a skimpy lace apron that barely covers the wild red bush between her legs, and a rope that ties her ankles together and prevents her from moving too fast or running away. Her enormous tits with their wide pink nipples are completely bare. She folds her muscular arms over them and hunkers down in her chair, whimpering with sudden shame. Everyone's looking at Livia, so nobody but you has noticed her. Yet.

"How did you do that? Are you a witch?"

"Wasn't me," you say. "Must be divine punishment."

"By the Ten Suns of Sindroth! I threatened to break my vow, and the gods punished me for it."

"Yes, that's definitely it. You'd better not do it again."

"But that means..." A red-hot blush is creeping over Gudrun's strong-jawed, handsome face as she begins to understand her predicament. "How long until the Festival of Fools, again?"

"Oh, quite a while. And I hope you haven't forgotten that I'm a patron of the tavern."

"So? I don't... wait. By Hela's horns!"

"That's right. You have to do anything I ask. So first I want you to let me play with those nice big tits."

"How dare you? I should smite you down for that insult!"

Suddenly, Gudrun's hands are tied together behind her back. You reach out and fondle her tits, hefting them thoughtfully and comparing their weights while she fumes and glowers at you. She could throw you off, but with your last prank you've successfully put the fear of the gods into her. She doesn't dare respond. You give her nipples a few pinches and pokes, then chuckle patronisingly and pat her cheek.

"I have a feeling you're going to get asked that a lot over the next few weeks. Anyway, here's what I want you to do next..."

Outrage, frustration and intense embarrassment all flit across Gudrun's face as you instruct her. When you're finished she stands and clears her throat, blushing bright red but too afraid of the gods' wrath to resist your commands. You've got her completely at your mercy.

"Everyone!" she cries, and all heads turn to look at her. There's a stunned silence as people realise she's naked, followed by a wave of laughter. She turns to face them, exposing her tits to the jeering mockery of the lowlives and blackguards who frequent the tavern, waiting for them to quiet down before continuing. It takes quite a while.

"No longer am I Gudrun the Great, Gudrun the Unconquered," she says in her loudest voice. "Now I am Gudrun the Nude, Gudrun the Conquered. This brilliant and handsome man has conquered me and made me his ****. I am to serve you all as a naked barmaid, slavishly obeying your every whim, until the Festival of Fools. You are all cordially invited to humiliate me in every way you can imagine, and invite all your friends to the tavern to witness my shame. I am a naughty little girl and I deserve it."

Total silence.

"Jump up and down!" somebody cries.

Gudrun, her face as red as you've ever seen anyone's face, begins to jump up and down. Her tits bounce. The tavern erupts into a riot of applause.

You spot Livia slip out a back door, unnoticed in your confusion, and smile to yourself. There's one more loose end to tie up here. And you do mean tie up.
