"I wish that I had male genitals!"
Yukiko giggled as the wand glowed.
Suddenly Naomi felt something being to push out of her crotch. She pulled down her jeans and panties to watch.
She watched intently as her clitoris began to grow outwards, merging with her pee hole to become a cock. Her vagina fused shut and she felt something growing where her vagina was. Looking down she saw she had a slowly inflating set of balls in a ballsack that was coloured slightly darker than her regular skin.
Her cock had not finished growing. It had grown in width as well as length and was starting to look like a real cock. Naomi had seen pictures of naked guys and their cocks so knew what to expect.
After a few minutes the changes stopped and Naomi looked at herself in the mirror. She still looked like a girl everywhere except for her crotch, where she now had a thick, long cock of 7 inches and a set of balls to match.
With a sense of excitement Naomi felt her cock, which sent tingles of pleasure through her body.
"This feels so good..." she moaned.
"I'm glad you like it" replied Yukiko.
What next?
