... change Edwin’s race. It would definitely be fun to see her sister in a different way, a different race, in fact, to match her different gender.
She selected the race change section and changed it for Edwin, inputting her new race as Asian, to be more specific, Japanese. She also made sure that reality changed so that everyone would remember her sister this way. The new Edwin would now be adopted by their parents, just like her. She then removed Edwin’s clothes with the Chronivac, so she could watch her new sister's race change in full. Before Edwin could protest:
Edwin’s skin lightened, the changes starting there first, first at her purple painted fingertips, then it spread to the rest of her body. As the change occurred it tickled her skin, and Dawn was surprised to hear her new sister laughing like crazy as her skin got lighter. The tickling spread through Edwin’s whole body, the skin becoming smooth and pale. Dawn guessed that Edwin probably didn't feel like protesting anymore, she could barely breathe through all her laughter.
Her face changed next, visibly becoming younger, looking to be around Dawn's age, as her skin was almost done changing, now bearing the appearance similar to that of a Japanese woman. Her hair turned jet black and lengthens down to her butt, a clip materializing on the right side of her hair.
When the skin change reached her breasts and vagina, however, she stopped laughing and began to moan. Arching her spine back, laid flat on her bed, her breasts and butt expanded as the changes seemed to focus around her torso next.
Once the skin change was over, Edwin stopped panting, passing one hand over her now much much more sensitive hairless light vagina, and then over her larger breasts and butt, going back to laughing as the change in pigment centers around her belly and back at the same time. Finally, the change stopped on Edwin’s belly button.
Edwin opened her eyes, recovering from her laughing/moaning and looked over her new body. Her breasts and butt were now bigger, but Edwin didn’t know if Dawn did that on purpose, or if that was just a side effect based on the anime shtick of Japanese girls having bigger assets. If it was true or not, Edwin no doubt did have such assets in her new form.
Dawn sat in the swivel chair, smiling, as Edwin explored her body. She knew that she had seen the Chronivac turn her brother into a girl, but using it herself was another thing entirely.
"The long black hair down to my butt is new..." Edwin thought to herself, but what was really odd was Edwin’s face. She seemed younger now. "Seems like I'm around Dawn’s age... Guess I'd need a new name, huh? Hmm... Emi sounds right!" The question was, what would the two of them do now?
