The Triumph of GPAD

As Victoria (formerly known as Jon) returned inside, she caught a glimpse of her own reflection in the hallway mirror. For the first time, she saw how she looked with her new, luxurious mane of raven black hair falling down between her shoulderblades. It was darkly beautiful, she noted with pleasure. She had become a living embodiment of the raw power of womanhood.
It won't be long now she realized delightedly. Soon, the last few scattered remnants of the boy named Jon would be wiped away, and only she, only the girl would survive. She butterflies of anticipation in her stomach, and a strange feeling of arrousal in her groin.
"You really do make a lovely lady," her mother commented, coming up behind her, and placing a reassuring hand upon her shoulder. "It must be nice to finally be free of all of that ridiculous male stuff."
"You have no idea!" Exclaimed Victoria.
"I hope you've given some thought to what it means to be a woman though," her mother said.
"What do you mean?"
"She means," Zoe chimed in, "that it's not all boobs and multiple orgasms."
"Zoe!" Her mother snapped even as Victoria giggled.
"What I mean," she said, turning her attention back to her other daughter, "is that you are now...or at least you're about to become...an heiress to...to the long and proud traditions of femininity."
"Among them boobs and multiple orgasms."
Her mother laughed slightly. "Yes, but not only is the point that I'm trying to make. Think Aphrodite, Athena, Helen of Troy, Joan of Arc, Cleopatra...you are about to become one of them! And that's why I'm so happy to see you go through this transformation!"
No, you're happy because the wishing stone made you happy, Victoria thought. But mom does have a point.
"Aaaanyways," her mother finished, "what I'm trying to say is, you know, spare an occasional thought for them? Because it's part of who you are now. There's a certain power that comes with being female."
"I'll remember that," Victoria replied. As her mother retreated in relief for having gotten that out of the way, it occured to Victoria that that had been ther first real heart-to-heart that she had had with her mother since she had been a little boy.
Just then Victoria suddenly felt her breath going faint, as if the world were contracting around her. GPAD was at last entering its final phase.
Zoe instantly noticed her discomfort; "Are you alright?" she asked in concern.
"I..." Victoria wheezed. "I need to get out of this corset..."
Zoe nodded and helped her sister strip off her dress, then, her fingers moving frantically, she unfastened her corset.
It was small wonder that Victoria had suddenly experienced such discomfort. Her breasts had finally ballooned up their full size, a respectable C-cup like those of Zoe and her mother. Zoe (who had been reading up on GPAD) knew what it meant; when the breasts attained their full size, the transformation was only minutes away from being complete. Already, if she looked closely enough, she could see the last details sorting themselves out; Victoria's face subtley altered, completing the process of feminzation even as her hips spread outwards by a small amount. The changes were small to look at, but they still caused agony for Victoria who screamed madly for several minutes.
And then it died down, as Victoria fell silent. She was lying on her back in the hallway wearing nothing but her god-ugly panties (underneath of which, Zoe knew from her research and a number of highly disturbing photos from the Internet) the penis had now fallen-off to make way for her new vagina. Her naked breasts rose and fell with each exhausted breath she drew in. But it was over. Jon was no more; he had become Victoria entirely.
He had become a woman through and through.
