"Huh. This is pretty neat." Amanda clicked around, intrigued at all the settings and choices the Chronivac laid out for her. Height, weight, eye color - even gender and age. It was like the most realistic character creation tool any video game could hope to have. Amanda laughed as she moved the slider for pubic hair back and forth, her model's genitals going from clean-shaven to an untamed bush right before her eyes. She hadn't clicked "Alter Reality", so nothing on her own body had changed save for the color of her hair.
Amanda found that right-clicking on her model and dragging turned it around, so she could see herself from every angle. She looked at herself from the back, frowning at the program's faithful depiction of her ass. Flat, and not very inviting at all. Come to think of it, she wouldn't mind making her breasts a little bigger as well. Not that it would do anything, she figured, but this program was miles better - and more realistic - than stuffing her bra. She let go of her model and took in a side view, wondering how she could make herself more voluptuous. Then it occurred to her.
"That's it!" Amanda said, snapping her fingers and grinning. She'd just caught sight of a button that read "Pregnancy." She remembered pictures in her family's photo albums of her mother's body from before Amanda was born - how everything about her had seemed to become rounder and more feminine. Making her model pregnant would cover all the changes she wanted to see. Besides, she was curious about how a pregnancy would look at her age. "Now, how does this work..." she mumbled.
Clicking "Pregnancy" opened a panel with several more buttons and fields for entering numbers. "Trimester" was there, and below that "Months", "Weeks", "Days," and "Hours." There were also fields for "Number of fetuses" and "Gender of fetus(es)." To Amanda's amusement, there were even boxes she could check. "Morning sickness." "Stretch marks." "Cravings." The list went on, and there were so many factors to keep track of that Amanda decided to keep it simple and not mess with most of them.
"Let's see...I'll give myself a baby boy," Amanda said, checking the relevant boxes. A box with a line pointing to her model's abdomen popped up, the outline of a baby emblazoned on one side and its vital stats on the other. "Awww...." Amanda couldn't help but blush at the cuteness of it all. "And let's make me...five months." She entered that into the proper field and watched in awe as her model changed. The virtual Amanda's belly, formerly flat and toned from high school volleyball, began to puff out and form a distinct curve, growing out into a little round ball. The baby's stats box changed, showing a half-developed fetus curled up inside her womb, an umbilical cord pumping nutrition into it from her body. Amanda unconsciously caressed her own flat belly at the sight, almost distracted from the other changes taking place. On the screen, her butt and thighs were thickening and gaining mass, developing her figure, making her even more curvaceous and womanly. The model's hair seemed to get thicker and shinier, and its breasts swelled out and sagged slightly from the weight of the growing milk ducts within, tan nipples and areolas growing and turning a deep chocolate brown, radiating blue veins throughout their owner's chest.
Amanda stared open-mouthed at the body on the screen, barely recognizing her own form. "It's so..." Sexy, her mind finished for her. Almost without a second thought, she clicked a button labeled "Animate." The virtual Amanda looked down and smiled at her gravid from, rubbing her belly and giggling as she felt her child kick.
The box from before popped up again. "Alter Reality?"
Quite without thinking, Amanda clicked "Accept."
