Li-Mei spent a month slowly getting used to her new reality. The now 50 year old woke up each day feeling a little better than the day before. The changes were subtle but she would occasionally notice a new black hair or a smile line fading slightly.
She took a vacation a few weeks after the discovery of her supposedly immortal body. Dr. Cho kept running experiments but other than confirming his original conclusions, they hadn't learned anything new.
On her way back home from her vacation in Coasta Rica, she had little to do in the customs line than contemplate her new reality. The recent vacation had been incredible and her growing energy levels helped her make the most of it. She shuffled through the line, wearing a loose fitting blue t-shirt, a long grey skirt, and some sandals. She got to the front of the line, giving the agent her boarding pass, passport, and ID, which had been hastily updated to include a new picture. The agent frowned a bit but let her through as she put her suitcase and shoes in the x-ray machine.
Fortunately, unless she stuck her hand in there, she wasn't at any exposure risk. She waited patiently for her turn at the scanner. Upon entering, she dutifully lifted her arms, waiting for the machine to whir to life.
"Oh, we still have the old machine here?" she overheard a customs agent say as the machine started.
"Yeah, they haven't replaced them with the magnetic ones yet," another replied.
Li-Mei's eyes widened as the machine whirled and coated her body in a low dose of radiation. Her head spun as she felt dizziness creep over her. When she was cleared to exit, she staggered out of the machine, remaining conscious this time, if only just. The agents looked concerned but she just smiled and said, "I just need the bathroom."
They let her stagger in without stopping her. She lurched toward the sinks after opening the door, feeling a strange tingle over her entire body.
She braced herself on the sink, leaning heavily as the radiation pulsed through her body. With each breath, she felt an exhilarating energy and as she looked up into the mirror, she nearly fainted again.
Her hair seemed to slither longer as most of the grey strands darkened to black. She could feel it creeping down her back, growing from her shoulders to about mid back. Her spine and legs started to shift from increased bone density and her body almost seemed a bit taller. Her face smoothed and brightened as only a few smile lines remained. Her mouth plumped up slightly and the small bit of sag around her neck firmed completely.
Her breasts quivered and firmed in her bra and she felt an odd, electric sensation as the nipples glided across the fabric. The band of her bra felt a bit tight while her stomach rippled, losing the small pooch that she had formed there in her mid 40s. Her arm and leg muscles felt a slight surge of strength and a great deal less pain. She had gotten used to minor complaints from her body and most of those faded as her vision stopped swimming.
She blinked in the mirror, noting she had to be somewhere in her early 40s now. She had a moment to take this in when a passionate tingle erupted in her pussy. She hesitantly rubbed it through the fabric of her skirt and panties and nearly passed out from ecstacy as hormones that had been dormant for years surged with a vengeance.
She staggered to a stall, opening the door and sitting down, letting her loose skirt pool at her ankles. Li-Mei noted her legs had not only toned slightly, but that almost all the cellulose that had gathered there over the years had disappeared. She slid a hand over her mostly smooth thigh, moaning from the sensation, as she reached another up to slide her panties off.
Her body arched at the exposure to the colder air. 'I'm so sensitive...' Li-Mei thought as she slid a finger delicately over the slit. Even that light brush against her clitoris nearly shocked her into an orgasm then and there as she felt her pussy dampen.
With a nearly sub audible cry, she said two of her fingers inside, rubbing slowly back and forth while another hand cupped her much firmer breast. With a snarl of frustration she she'd her shirt, once again cupping her breast but this time under her bra. Each pinch of her nipple sent shockwaves of electricity through her and her back spammed into a bow with each touch.
Her fingers worked faster now as she required her atrophied skills, each stroke pushing her closer and closer to the edge. Her womanhood was slick and each wave of pleasure spurted more and more over her fingers. She joined her thumb to the collection of sensations, stroking her clit, and with a shuddering moan, she cried out in orgasmic ecstacy for the first time in decades.
As she felt the surge subside, she looked over her transformed body. If she had to guess, she was perhaps no older than 40 now, and with a shudder, she realized that she just went through menopause in reverse.
"Now what...?" she muttered, panting from the recent exertion.
