Ass expansion ensues.

As Samus' mind wandered at the possibilities of the merged hourglass chip the technology began to integrate itself with her body. A slight coldness spread throughout Samus' deepest points, each cell quickly being altered directly by a flood of microscopic body altering robots, each one attaching itself to her very atoms.

Samus eyed herself in the mirror as she felt the familiar feeling of impending growth, she was on the edge of her seat waiting to see herself with a big rack and a much fatter ass. The robots initially worked on editing her entire body to coincide with an hourglass figure but quickly spread downwards into her hips, butt and thighs. Samus' entire lower body was internally enveloped by the ass-enlarging tech, as they finished their job of altering her basic DNA, the feeling quickly disappeared.

Instead of directly adding sheer size to her ass themselves the bots reconfigured Samus' DNA, tricking her body to believe it was always an **** hourglass shape, voluptuous all across the board. In addition, a function was added that allowed Samus' body to expand naturally when said voluptuousness disappeared, assuring she'd be a permanent hourglass. As Samus eyed herself in the mirror she began losing her patience, that bots had taken awhile to get the job done and she was eager to see the results. "What gives?" Samus said to herself, in that instant her hips began to almost vibrate as they slowly began widening themselves out. Her lower body quickly got wider, approaching her shoulders in width and easily surpassing them before settling down. Her bones didn't crack at all, completely and smoothly transitioning into wide, child-bearing hips they were meant to be all along. By now Samus already had an **** hourglass figure, and her ass wasn't even done yet!

Samus noticed her thighs were disproportionate to her hips width, as she viewed her legs in the mirror this was a bit off-putting. She wanted to be voluptuous, not thin with wide hips! As her apprehensive eyes travelled over her widened hips she was pleased to see them rapidly filling out, perfectly flooding her legs with soft thigh flesh, perfectly formed and extremely wobbly under her skin tight suit. Immediately after Samus noticed that as her thighs grew her ass did too, it felt much bigger than usual, and it was still growing! She turned around to get a better look at herself, moving her eyes to view her perfect butt in the mirror. Before she had taken the hourglass chip she had a very slim, athletic ass but before her very eyes it was growing in size and volume, her flesh quickly spilled outwards and swelled to look like the absolute best of bubble butts. It was in its own tier entirely, each round cheek must have been at least the size of her head she thought.

Samus gave it a quick slap and watched how fantastically it bounced and jiggled in response. Her zero suit seemed to be even more form fitting around each globe, giving her ass an amazing outwards appearance and allowing **** amounts of jiggle as she began walking. Samus spun and strutted around, watching her embiggened boobs and breeding hips bounce and sway, accompanied by ridiculous amounts of jiggling for someone wearing clothes. Even her boobs seemed to have gotten slightly bigger and her nipples pushed against her suits fabric ridiculously hard, the process turned her on way more than she'd expected. Samus looked into the mirror and struck a pose, displaying both her cow-tits and her perfect booty. She was a complete bombshell and couldn't help but smile at her new hourglass body.

But now, she was just a perfect bodied bounty-hunter in the middle of the station. The universe was still her oyster, anything could happen next.
