Jake looked through the various settings. Up near the top was a small drop down menu labeled 'Presets'. Upon clicking it, several settings were revealed. Some highlights included a species randomizer, a pool party option, as well as other aesthetic changes such as goth and e-girl. What caught Jake's eye was something on the more tame side of things. After all, it would be a little rude to start with something too extreme. He moused over the '1-to-1 Gender Swap' preset, revealing the tooltip.
"Switches genders, male to female and vice versa. The Chronivac will adjust the optimal physical settings to make your natural feminine form." It read.
"Perfect." Jake thought to himself.
He selected the options, and noticed a few settings changed on Nathan's profile. It now read:

Jake skimmed it over, nodding silently in affirmation. He glanced over at Nathan, who was browsing on his phone, waiting for Jake. What Jake didn't realize was that he was still scrolled down on the program, and his profile was open above it. The presets provided affected all currently scanned users. Out of his view, his profile now reported:

"Now watch this!" Jake exclaimed as he clicked the 'Save Changes' button. He looked over to Nathan, who was now tensed up in anticipation. The emitter shot out a beam covering the both of them.
Nathan's hair started to lengthen considerably, going from extremely short to flowing in seconds. It had a shiny luster to it, growing down past his shoulders in a straight styled cut. His face changed next, with his eyelashes growing much longer, a thin coat of makeup adorning his face, and the smoothening of his skin. He let out a short gasp, feeling the changes flow downwards.
"Jake... What the hell did you do..." He grumbled, his voice climbing higher.
"You'll see!" Jake coughed, his voice also beginning to change.
Nathan felt his shoulders crash inwards, and his upper body lose a touch of muscle mass as the testosterone was drained from it. Replacing that was a tugging feeling in his chest. He stifled a moan, threatening to slip out as his nipples grew harder, and far more sensitive. He glanced down into his now too large shirt, only to be met with the sight of flesh amassing, growing for what seemed like an eternity. He looked down to see his new cleavage, giving his breasts a small squish.
"You turned me into a girl?!" Nathan squeaked, blushing as he looked up at Jake. "But wait... Why did you change yourself as well?"
"Ha! Nice try. I wouldn't— Oh no..." Jake went quiet as a curl of hair tumbled into his vision.
Jake ran his hands through his hair, which grew rapidly. The length amplified its waviness, and it extended to just beyond his shoulders. Similar to his friend, Jake's face also feminized, although it actually became a little rounder rather than slimmer. He groaned as he took a look at the computer.
"Fuck... Looks like the presets apply to everybody." He grunted as he felt his chest grow outwards, biting his lip lightly. Jake's chest swelled to a size slightly smaller than Nathan's, hanging in his shirt without a bra. He also noticed his hands becoming a little daintier, and his nails receiving a simple manicure. Nathan leaned over to look at the laptop, reading the changes.
"Heh, serves you right Jade." He emphasized Jake's new name.
"It was an accident you, uh... What's your name? Natalie!" He attempted to retort.
Natalie's changes continued down his torso, slimming his stomach and removing most of his body hair. Eventually the changes reached his crotch. He sighed, knowing what was coming. His blush intensified significantly. He spread his legs out a little bit in response to his cock shrinking back into his body. Replacing it was a strange warmth radiating in her pants. She nervously slammed her legs together.
Meanwhile, Jade was dealing with his own changes. As indicated by the Chronivac, he ended up gaining a small bit of weight, leaving his stomach a little chubbier than before. He looked down and grimaced.
"Is the program supposed to do this- Mmf!" He moaned, the changes to his genitals obviously catching him by surprise. Natalie smirked as she watched.
Jade panted heavily as his dick receded, replaced in its wake by a hot, wet slit. She patted it through her underwear, feeling how warm and wet it was becoming already. Her underwear dug more into her new sex as her hips buckled outwards, becoming quite wide. Her thighs began gaining mass rapidly, matching her slightly chubby frame. Accompanying that change, her ass swelled considerably, making her seat on the couch all the more comfortable.
"Wow, you got some serious thickness!" Natalie said, grunting as her own lower half changed.
"S-shut up..." She sheepishly said to her friend.
Natalie shifted in her seat as her thighs and behind also grew, although they were smaller and more toned than Jade's. She then stood up, legs pressed together as she held up her large jeans. Jade followed suit, although her pants stayed up on her hips.
"Hey look, I'm actually taller than you now!" Jade smirked, putting her hands on her hips.
"This is just... too weird... I can't believe that thing works... I guess this is a girls sleepover now?" Natalie said, looking down at the laptop.
"I guess so. We always dreamed about going to these sorts of things. I wonder what the guys at school would think of us... Even though I'm still totally into girls..." Jake trailed off.
"We can send them pics or something later. For now, what the hell do we do with the Chroni-whatever?" Natalie sat down with the laptop in front of her.
