"Here, drink this. It is a truth potion," Amya said, pressing a small green vial into Brian's hands. "It will let you hear the truth he is thinking, even when he lies. That way you will be sure to seduce him, as you will know whenever he becomes suspicious."
Brian took the potion without question and poured it into her new, dainty mouth, the green potion dripping onto the floor momentarily. Then it stopped, and trickled down her throat and into her dress.
Amya began chortling, drawing a strange look from Brian. But when he opened his mouth he gasped, because in both mirrors his mouth was that of a beautiful maiden. A tingling started in his throat and over his face, and ran down his stomach. Then the tingling became pain, and brian slumped to the floor, his head pounding with the laughter of the evil sorceress.
"You fool," she laughed. "You will get your revenge on him, but in my own time. For now, you will stay here with me and learn to become my apprentice. Once I have taught you all that I can, I will leave behind this ancient body and inhabit yours. This is the way that I will live forever!"
Brain could do nothing as the transformation continued, burning away at his gut and slowly seeping into his other organs. His skin felt loose and baggy, but the orcs' hands on the dress' ties held him in place. Soon he knew that there was none of his old body left, and as the pain receded he felt as light as a feather.
"And now.. to make sure you are a willing pupil" she grinned, and dropped a purple amulet in front of her face.. Brain's eyes went wide as she was captivated by the gem, unable to blink as phantasms of her memories as a man were drown out from her forehead. As they were drawn out, new ones surfaced with the proper genders. Instead of experiencing his first kiss as a man, she remembered a torrid affair that left her naked, breathless and in her lover's arms. Instead of remembering riding horses and hunting, she remembered playing with dolls and singing songs. As each memory was replaced, she became less and less furious with the sorceress, and more desiring to be the sorceress' apprentice. When the last one was gone, Brianna rose, grinning happily. Amya had just agreed to let her study and learn from her magical grimore! And from the grin on Amya's face, she was just as pleased with her new pupil.
