Jeff looked around blushing as he pressed into his empty fabric groin, it tingled with every stroke of his hand that brushed the fabric of his groins new skin. Jeff then bent around and stroked his panty ass and pressed in on where his butt hole was and found nothing but inflated fabric as it gave, then filled back up with air as he let go. The squeezing sensation was enjoyable, anus-less and dick-less but the feeling felt wrong, like there was no pressure when his fabric skin wheezed from being squeezed and let go.
Jeff then started to think of balloons and how latex rubber holds in air much better than cloth. He then though of how rubber panties might give more of a stimulating effect than cloth panties, and Jeff with a bit of a blush and a slight giggle went to the chronivac to change his body again, this time turning the pink fabric into red latex rubber.
As the tingling started, it grew and grew, Jeff reached down to grab his crotch as it let out a tight rubber squeak, his hand stroking a taught rubber version of his panties from before felt invigorating, the vibration of the crotch reverberated around to his ass as his panties changed into rubber. he felt arousal in him as his new rubber panties were taught and filled with air, just like the cloth ones were, he pressed into his groin and gasped as his groin caved, stretching as his hand pushed into him. he felt his ass push back as if trying to burst as he pushed his hand in deep. Jeff reached both hands around back and pushed deep into his ass, and the pressure forced his crotch to bulge slightly, sending deep moans of pleasure coming from Jeff, but strangely, no orgasm came from his self molestation, if he stopped for a while, things seemed to calm down.
He got up from his chair and felt the tight balloon of his waist squeak and flex as he walked around, sending rubber squeaks coming from him and more ecstatic pulses through his pelvic region. Jeff liked this as he pranced about for a while before sitting back down at the chronivac, his rubber butt letting out a loud creak. Jeff sighed and wondered what to do next...
