"Stop!" Amanda cried and sure enough, it immediately halted on 22 years, 6 months, 4 days, 5 hours, 20 minutes. One look to Candice's timer and it read more or less the same except the minute counter was on 10 minutes.
"Well, I guess that's old enough for now," said Candice, "Don't want to get too old." Amanda looked at the woman who was formerly her daughter. Her sundress had become a pink halter top and a Demin skirt that goes down her thighs. Her midriff was more on display and showing off her curvy waistline. Her pink sandals had shifted around her growing feet as they became a pair of pink sneakers with rhinestones on the sides forming an outline of a heart while ankle socks grew out of them. Her pink diamond ears had extended down by the chains and shifted into a pair of hearts. And to top it all off, she had a pink fitbit watch on her wrist and a necklace wrapped around her neck with the word 'princess' on it. Candice ran a hair through her long blonde ponytail as she looked at her reflection. "Damn, I grew up to be a total knockout," she said, posing. Amanda felt a little jealousy at how Candice's CC breasts filled up her halter top.
Of course, Amanda herself wasn't homely. Now that she was back before she got pregnant, her figure had slimmed down to before she got the baby weight. Her skin no longer sagged and her tattoos looked more vibrant. With no grey in her hair and no wrinkles around her eyes, she looked as fresh as a college girl. Which considering she was 22 and a half, she probably was one now. She would be enjoying this more if her former daughter weren't of nearly the same age and outranking her in the curves department. "Ok, this is fun, but maybe we should change back," said Amanda.
"Already?" whined Candice, "But I just got like this."
"And you'll see it again when you grow up the natural way," said Amanda.
Candice pouted and said, "You can't tell me what to do. I'm an adult now."
"But I'm still your older sister," said Amanda. She paused. She had meant to say 'mother', but that just seemed ridiculous now.
"By only 10 minutes, which you've been hanging over me my entire life," said Candice. She paused too. Why would she say that?
Just then, both women felt a tingle through them. Amanda looked at Candice and noticed some changes. Her blonde hair was shifting to a light brown much like her own hair. There were also changes in her eyes and facial features. It took Amanda a while to realize that Candice was losing all the traits she had inherited from her father (which Amanda was having a harder time picturing) and becoming more like her. Similarly, Candice noticed that Amanda was getting a little bit taller until she was of equal height. Similarly, her hips and rear pushed out more to match hers. Her crop top suddenly bulged out as her breasts surged up to CCs.
When the changes stopped, it had become clear that the two of them weren't just twin sisters, but identical twins. Amanda had gained her sister's figure while Candice gained her sister's features. In fact, asides from their hairstyles, clothes, and Amanda's tattoos, they couldn't be told apart from each other. Memories soon flooded their minds of growing up together on similar but slightly different paths. Now the two of them were in their final year of college together.
Candice adjusted to their new reality first. "Well, Mandy, ready to have some fun now?" she asked.
"What did you call me?" asked Amanda.
"You know, Mandy and Candy, the fun twins?" asked Candice, "Don't tell me you don't want to try this out."
Amanda found herself slipping into this new mindset rather easily. She had to admit she missed her wild days and now she had a sister to be her wingwoman. "Is there anything you want to do?" asked Mandy to her twin.
