Mike and Randy's mom, meanwhile, didn't notice as her vagina was replaced with a 6 inch penis.
Mike's former wish didn't just change mom's perspective - it seemingly changed reality.
Back with Mike and Randy, the two began arguing.
"You gave MOM your old cock?!" Randy was shouting.
"I... yeah, I did, okay?" Mike said.
"WHY?" Randy asked.
"Because I couldn't think of another pussy!" Mike said.
"Ugh... this is a mess..." Randy said.
Mike had an idea.
He called Balthazar in his mind and asked him a question.
"Balthazar, I know this is asking a lot, but is there a way I could... copy body parts instead of swapping them?" He asked, in his own head.
"I'll do you one better! I'll let you manipulate body parts however you want." Balthazar said.
Back in the real world, Mike decided to test it out.
As soon as the thought entered his head, Randy started changing.
"Mike... what's happening to me-e-e-e-e!" Randy said, as his voice pitched up.
His adam's apple disappeared as his face became smaller and daintier, his hair growing down his back. His nose shrunk as his eyes got bigger and his lips puffed up.
From the bottom of his neck up, Randy was now a girl.
"W-what happened?" He said, meekly.
"Look in the mirror!" Mike said.
"Oh my God! And... my voice..." Randy said.
"That's not all. I gave mom her pussy back. You have a normal 18 year old's pussy now." Mike said.
"Who'd you steal it from?" Randy asked.
"I didn't. I made it up. Watch, I'll show you." Mike said, focusing again.
Randy's entire body shrunk down as his body hair disappeared. Two large orbs began growing from his chest and his waist pinched in. His hips expanded before a large ass grew. Small changes continued until Randy could finally feel the sensation slowing.
"Oh... my God... I'm a girl!" Randy said, excitedly.
"A pretty one, too." Mike said.
Mike was right. Randy had long, brown hair; a cute button nose; puffy, but not too big, lips; and a slender but curvy frame, with large D cup breasts.
She also had a new outfit - A sweater that accentuated her large breasts and a knee length skirt, with knee high socks and flats on her feet. She had a bit of a nerdy look to her, but she was still gorgeous.
"I guess Rachel'd be more fitting now, huh?" Mike said.
"Yeah... I think I like that. Rachel." Rachel said.
"Now... let's see if I can improve myself..."
Mike said as he focused on himself.
The breasts that formerly belonged to his sister began to expand... and expand... and expand, until they were huge caricatures of their former selves. They had to be at least a G cup now.
Then, he focused on his womanly hips, making them stick out even more. His ass quivered as it grew as well, expanding into an even bigger bubble butt.
Finally, "Michelle" feminized the rest of her body... except for her cock.
Just like Rachel, her adam's apple disappeared, as did her body hair. Her face shrunk down and became a woman's. She gave herself long, blonde hair to contrast Rachel's brunette hair.
She made her legs longer and more slender as her frame shrunk down. With a few extra touches, she gave herself whorish makeup, a sexy schoolgirl outfit, and lengthened her nails until they reached an inch from her finger tips, topped off with bright pink nail polish.
If Rachel was the nerdy but sexy girl next door, Michelle was the school slut, with one BIG exception... she'd grown the cock between her legs to a full foot, the monster ready to fuck any girls she came across, the huge bulge obvious in her miniskirt.
"You like it?" She said to Rachel, her voice high pitched and slutty.
Rachel was speechless... and aroused...
