While Emily was distracted thinking about her new life, Jeff decided to try something. He first changed her back to her original height, and Emily felt herself growing again. She then exclaimed, "I'm growing again!"
"That's great, sis," Jeff replied.
Emily watchedin awe as she grew to 3'8", then to 4'8" and stopping there. "I'm my normal height again!" she said with glee.
Jeff then changed some settings on the chronivac, and pushed enter. He watched as Emily made sure that everything about herself was in order, then she got up and hugged Jeff. As she hugged him, Jeff watched as her ears moved up to the top of her head, taking on a cat-like appearance that was the same colour as her hair. He then watched as Emily then let go of Jeff, and went to watch tv, not noticing that a tail was growing just above her ass. As she sat down and turned thhe tv on, she winced from how loud the tv sounded to her. She then didn't notice as she grew older, growing DD-cup breasts and growing taller. Jeff observed that Emily had grown to just under his height, and started looking a lot more like him, but as a girl. Emily then noticed, and looked up at Jeff with bewilderment. "What's happening, Jeff?" she asked.
Jeff then replied with: "you should know, you are my twin after all, Em."
"What do you mean by 'your twin?' I'm 10, and you are 15," she replied with a confused look on her face.
"You are now my twin sister, Emily, because you are now 15 years old, like me," Jeff replied.
Emily then just stared in shock, "Y-your twin sister?!"
"Yep, and you are also a neko, you have the tail and ears," he said.
Emily's hands shot up to her ears, finding cat ears on the top of her head instead. She then brought her hand down to just above her ass, finding a 4-foot-long tail where earlier there had been nothing, "I-I'm p-part c-cat now?"
Jeff smiled, "no, you are my part-cat twin sister." He then changed some settings on the chronivac when Emily was distracted by her tail, "and you have wings."
Emily looked up, staring at Jeff in stunned silence, then a 22-foot-long-wingspan pair of wings popped out of her back, and Emily fainted from the shock as Jeff set the changes to permanent.

Please add more to this branch, I'd love to see what becomes of it... Will it be sex? Or will it be Jeff changing to match Emily? The choice is yours! Have fun, and make this branch interesting.
Thanks!
