Seeing Tim's reaction, Katie first thought she had something on her face. She a hand to the area around her mouth and quickly noticed that her fingernails, which she habitually bit down to nubs, were now perfectly trimmed and manicured, extending slightly beyond her fingers and ending in white tips. Out of the corner of her eye, she saw something that made her look down. The white blouse of her school uniform was being pushed outward by what looked like a pair of actual, visible, somewhat generous breasts. She reached down to touch them, and they certainly felt real, as if she'd somehow gained some new fatty tissue deposits under her skin.
Katie turned to look at Tiffany. Tiff didn't seem to be any better endowed in the chest area, but everything else about her seemed to be tweaked somehow, as if someone had worked on her with an airbrush or Photoshop. Her eyes were slightly bigger, and a deeper shade of blue. Her nose was slightly smaller. Her cheekbones were slightly higher. Her skin was no longer freckled; instead, she had an even, bronze tan. Her brown hair was longer, now reaching almost to her waist, and had gained blonde highlights.
"Oh, my God, look at you!" exclaimed Katie.
"Look at me? Look at you!" exclaimed Tiff. "You're, like, 6 inches taller! And I love your hair! And I sure as hell can't call you 'No-Cans'!"
Katie reached up to feel her hair. Instead of the fairly close-cropped style she'd had it in, it seemed to have doubled or tripled in volume and was now chin-length. She began, "So when I picked 'Enhance' on the control panel..."
Tim finally found his voice, high and squeaky as it was. "So that's what that meant! You two were trying to enhance yourselves. Now I think I understand what was going on."
"So the machine did this," said Tiff, reaching down to feel the smooth skin on her legs, between the bottom of her plaid skirt and the top of her calf-length white socks.
"Yeah, but this is a little weird," mentioned Katie. "I was wearing a training bra. And it must have gotten bigger or something, because I can feel I'm wearing a bra that's the right size."
Tiff pointed out, "Also, you're taller but your skirt still comes down to your knees, so that must have changed size, too."
"And your glasses are different," Tim said from the machine's control panel, which he was examining. Both girls looked at him, and then Katie took off the glasses, holding them close to her face so she could see them. Indeed, they now had black metal frames instead of silver ones.
Tim went on, "As I was saying, this thing appears to be a quantum reality modification device. It enhanced you by changing the fabric of reality a little, so in some ways, this is now how you've always looked -- well, you know, I mean you normally grew and matured into bodies like this. So you own clothes in different sizes now."
Tiff and Katie looked at each other. Katie asked, "So if I go home, all the clothes in my closet will fit me like this?"
"I think so," answered Tim.
"And our parents and everyone else won't think there's anything weird about us coming home looking different?" asked Tiff.
"Hmm, I'm not sure," said Tim. He turned his attention back to the control panel. "I've found the advanced settings, and there does seem to be an option for extending the effect of the reality modification --"
Tiff rolled her eyes. "Great. Well, how about an undo feature?"
"Yeah, it looks like it has that," Tim responded.
"But I want to stay like this!" exclaimed Katie. "Can't we just go back in and have Tim make sure it's set so everyone will remember us looking this way?
"I don't know..." started Tiff.
Katie suggested, "Or we could change back, but give ourselves some enhancements that aren't really obvious. Like these fingernails could probably stay -- oh, and maybe no more PMS!"
As the girls discussed their options, Tim stayed out of it, instead trying to figure out everything he could about the computer interface for the machine. He'd gotten it into "admin" mode, and now it seemed fairly simple to get it to do exactly what he wanted.
Finally, the girls made their decision.
