Jeff mulled over his options but one kept popping back into his head. Once again becoming part swimsuit, but this time, instead of a full change, only part of him was changed. As the thoughts kept creeping back to him he thought about it again and again, looking back at his dick and the chronovac for a good five minutes before deciding on his course of action.
He would become part swimsuit, more specifically, part girl's one piece. Only this time, he would still be humanish. Already deciding on it Jeff began to get the chronovac ready, setting the transformation to take thirty minutes and lasting until he said so.
Clicking start Jeff leaned back in his chair, smiling as the changes began.
First his scrotum started turning blue, his balls shrinking back into him slowly as Jeff caressed them, smiling as his balls shrunk away into him, leaving behind blue rubber just like before as Jeff felt a small cavity open just behind the rubber.
Looking at his dick Jeff watched his the blue slowly spread up it, all the while feeling his body cavity expanding slowly as his internal organs started to dissaper. Jeff rubbed his blue rubber dick as is started shrinking, moaning in pleasure as it quickly sank into him, leaving a flat rubber surface on his front, the first part of his swimsuit body.
The rubber quickly spread around his hips, ignoring his legs as his ass turned blue and rubber, smoothing over as Jeff slapped his ass, giggling as it jiggled, the muscle slowly dissapering as his body cavity expanded.
The rubber quickly began spreading up him, passing his stomach and smoothing over his belly bottom as his stomach dissapeared, his body cavity expanding behind the rubber as Jeff pushed on his rubber body, smiling as it pushed in under his hand before pushing back out when he let go.
The rubber quickly spread up his torso, half of it already rubber, and half of his inner organs gone, replaced with an empty body cavity befitting that of a swimsuit. Already Jeff had plans to go swimming, just to see what would happen when he did.
His transformation speed up slightly, Jeff's breathing stopping as his lungs and heart dissapeared, his body cavity taking over where they used to be as rub sped past his nipples, smoothing them over and leaving nothing in their place.
Jeff was giggling with glee as he pushed his sides, watching his swimsuit body deform into an hourglass figure as he pushed the two sides together inside his body cavity before letting go, letting them pop back out as the rubber reached his neck before stopping as his body cavity finished expanding.
His entire torso was a hollow swimsuit, leaving only his legs, arms and head flesh as they appeared to come out his his body where they would on a swimsuit. But his change was far from over as Jeff stood up from his chair.
Jeff crossed his legs and moaned as his lower torso started to contort, becoming the bottom of a girl's one piece as his ass appeared to fill out in the shape of a girl's ass, despite being nothing more then an empty rubber cavity. His sides popped into an hourglass figure as Jeff moaned, his body shrinking slightly to match the size of his swimsuit body as two small lumps formed where his chest should have been, the false breasts pushing out against the rubber that, upon closer inspection, were both very pleasurable and able to be pushed into his body cavity like the rest of his swimsuit self, but still popping back out into the breasts.
His legs started to slim to match the girlish proportions of his body, his arms following suit and becoming dainty as Jeff's face contorted into a wide grin. As he giggled girlishly, moaning as his face contorted into that of a girl's and his hair grew out behind him. He was genderless, but clearly feminine.
Opening her eyes the swimsuit girl smiled as she gave herself a quick new name, Jen.
Jen smiled as she played with her body before striking a seductive pose in front of her bedroom's body mirror, slapping her hollow ass and watching it jiggle with a giggle. "That was lovely, now what shall I do?" Jen asked herself
