"Mistress... I want to become a female. Not just act like one, become one..." Tails whispered.
"Well you have the means and the know-how Tails, do it. Make yourself a machine that will fix you." Rouge replied.
"Yes Mistress, thank you!" Tails squeaked, and he began to get to work. As she watched her pet build his machine, Rouge began to fantasize about what she would do with this machine. She could have, Sonic, Knuckles, Shadow, and Silver join Tails as submissive female slaves, and they would love her for it! Of all of them, she felt Silver was the biggest threat. As a psychic, he could tear apart Rouge's hold on anyone as if it were a wet paper bag. Shadow would also be a problem, with his vast powers, she'd probably need the others on her side to stand a chance. Sonic would be tough, but not impossible. She could trick Knuckles just as easily as she fooled her trusting, naive twin-tailed captive. Before Rouge could wonder about the future anymore, Tails finished his machine, and climbed into it. "Wish me luck Mistress!" Tails called, and dropped in before turning the machine on.
A bright flash was emitted from a metal canister that held Tails, and the fox was then bundled into the rest of the machine. After a while, Tails stepped out, and Rouge's jaw dropped at the sight.
Standing at the exit of the machine was a fifteen year-old vixen, with an impressive C-sized bust. She had long, slightly curly blonde hair, a small cute nose, a soft facial expression, iridescent blue eyes, wide, child-bearing hips, a shorter muzzle, and a coat of luxuriously soft, fluffy yellow fur. She was clad in an exact copy of Rouge's outfit, downsized to fit her, and the exact same makeup. Rouge wrapped her arms around the vixen, and smiled.
"My little boy has grown up into a beautiful woman." Rouge sighed. Tails blushed. "Well Tails-"
"Please Mistress, call me Tiffany." The younger woman cut in.
"OK Tiffany, I want to get you a present. A very special present." Rouge said seductively.
"What sort of special present, Mistress?" Tiffany replied, blushing.
"A slave of your own. Someone who has wronged you in the past. Maybe that bitchy swallow, or that stuck-up vixen." Rouge replied.
"Oh, I love that idea. I think I'll have..."
