On their way to get some clothing, Tammie noticed a couple of bottles, filled with a softly glowing liquid, on a shelf. "Say, Alexsandra," she asked, "what are these?"
Alexsandra poked her head around the corner. "Oh," she laughed. "Those are what we call 'revenge in a bottle.' One of the earliest female members of the palace staff was wronged by a man, but what he didn't know was that she was a talented alchemist. She mixed the first bottles of those two potions, and taught the other women of the palace how to make them. Their concoction has been a closely guarded secret of the women of the palace ever since."
Tammie's ears perked. "What do they do?" she asked.
Alexsandra smiled. "The green one, if you drink it and then kiss a man, will change him into a woman. The blue one, when used in the same way, will put a female version of his personality into control of his body, while his male self will remain in the same body, able only to see, hear, and feel what the female self does. Don't drink them both, though. That will negate the effects altogether."
Tammie grinned, and even Janice perked up a bit. "Can we...use them?" she asked.
Alexsandra smiled. "Of course," she said. "It is one of the benefits of being part of our palace sisterhood. But I assume from this that some man has wronged you?"
"Um...he was a powerful magic-user who intended to make us his slaves," Tammie said. She didn't want to lie to the woman who'd saved them from the guards, but if Alexsandra felt as strongly about the prince as she said she did, Tammie thought that she'd probably object to what they were planning, so a little obfuscation was definitely in order.
"I see," Alexsandra said. "Take it, with the blessing of all the sisterhood. But be careful. The potions will work even on the strongest magic user, but don't give him a chance to work his spells on you. Pretend that you've succumbed to his will, perhaps. That may put him off his guard. Luck be with you both."
"Thank you!" Tammie and Janice said in unison. They each grabbed one of the bottles and ran off, still naked, to plot their revenge.
