"I wanna be bigger!" said Candy immediately.
"Whoa, whoa, slow down," said Amanda, "We haven't agreed to anything yet."
"But I want to see what I'm like when I'm older," said Candy.
"And I'm already plenty old enough as it is," said Amanda, gesturing at her wrinkles and her grey hairs, "If anything, I want to be younger."
"But I don't want to be a little kid," whined Candy.
"That is not a problem," said the room, "The Mysterious Aging Room can make one person progress while the other person regresses as long as they still have separate counters."
"See? Now you can be younger while I can get older," said Candy.
"Ok, ok," said Amanda, "We can do it your way." Not that she really believed that the room could do anything at all. Though having their names and exact age were very uncanny.
"State your direction," said the room.
"Progress," said Candy.
"Regress," said Amanda.
The two counters responded to their words. Candy's counter started going faster, the seconds, minutes, hours, and days quickly becoming an unreadable blur. Only the months and years were still readable as they moved faster in time. Amanda's counter sped up the same way, but her months and years were going backwards. Amanda wasn't impressed with this as she still didn't believe.
"I'm feeling weird," said Candy. Amanda looked at her daughter and froze in surprise. Candy was definitely getting taller now. Her sundress was being pulled up her legs as she gained more inches. And if that weren't enough to convince Amanda, a pair of bumps appeared on Candy's chest that began slowly pushing out.
"Candy, you're getting older!" cried Amanda in shock.
"And you're getting younger, Mom," said Candy, her voice getting a little deeper as her face was becoming less round.
Amanda looked at the mirrors and saw she was right. The changes were subtle right now, but they were getting more obvious. Her grey hairs were regaining their full color as her wrinkles were fading away. Her muffin top was shrinking as her breasts were regaining their perkiness. The faded tattoos were getting more vibrant while the C-section scar on her stomach became deeper.
Turning back to Candy, Amanda saw she had entered teenagerdom. She gained more height as her hips started to flare out. The bumps on her chest had grown into full A cup breasts that were rapidly heading into B cup territory. Her face no longer looked childish as pimples appeared and disappeared regularly. But more importantly, Candy's cloths have also changed. Her sundress had split in two, becoming a halter top and a skirt. Her midriff was being put more on display as she gained height.
One look at the counters showed that Candy was now 15 years old while Amanda was 20. And while they both remembered who they were when they entered the Mysterious Age Room, new memories and knowledge were entering their minds. For instance, Amanda was recalling the day Candy was born differently as she became a mother at an earlier age. Now she had a daughter that was half her current age and if the progressing and regressing continued, their relationship will change drastically.
