Doris chuckled, watching as the days were falling away with each step. "39 years 10 months and 29 days," she smirked. "Yeah if only a jog could knock my age back."
Pausing her jog she now wiped some sweat from her brow as she gazed at the readout. "I wonder," she said softly. Pressing a couple of buttons Doris figured out she could adjust the settings. Now instead of days, she could take months. "Screw it might as well have some fun." Starting the treadmill once more Doris watched as her age began to change once more.
10 months, 9 months, 8 months.
Doris chuckled softly, she wasnt sure what the gag was but she would roll with it. As the timer continued to tick down, Doris failed to notice the changes.
The fine lines around her eyes began to fade, the few stray greys littered in her ebony locks vanished, even the few extra pounds she had put around her midsection melted away. Doris was feeling more energetic with each step, still oblivious to her youthening body.
Doris gazed down at her vitals after a few moments, her eyes going wide as she crossed the threshold of her thirties. "Woohoo 29," she exclaimed. Doris couldnt help but smile, her vitalsnlisted her as 29 years 11 monthes and 29 days a full decade younger than she had been.
"Well this is a hell of a motivator I'll give them that," she thought. "And I do feel great. In fact let's see just how far I can go."
Doris continued to run, her age continuing to tick down. The formerly middle aged mom unaware her body was continuing to grow younger, the stretch marks from her pregnancy slowly vanishing, her face becoming fresher, her D cup breasts firming and ebony hair glowing. Glancing down at her vitals she gasped.
"20 years 11 months and 29 days," she thought in alarm. "Geez a day short of 21. Good thing this is just a gag, otherwise I'd be barely older than my kids."
Doris now found herself lost in thought. Remembering her 21st birthday, how her friends had gotten her drunk, how she had puked all over some guy they had met at the college bar, all the while unaware of the changes taking place.
Doris body was slimming, her breasts decreasing slightly in size as her face became rounder and more innocent. The womans yoga pants now appeared a little baggy around the college coeds waist, her stomach flat, her body toned, and all of it hidden under an increasingly baggy tshirt.
Doris says still lost in thought as she began the decent through her teens. The college girl quickly became a high schooler. Doris was becoming skinnier, her yoga pants losing their hold as her hips narrowed and her butt flattened. Unconsciously the now teenage girl adjusted a now roomier sports bra as her breats continued to decrease.
"Weird," she thought. "Why is my sports bra loose? Did it get stretched out?" A quick glance at her vitals didnt alarm the teen as it read 16 years 5 months and 13 days. Unfazed Doris continued to jog, she couldn't believe how great she felt. Chalking it up to a runner's high, the teen pressed on.
The changes now really began to take hold as Doris raced towards the beginning of high school. The teens face was rounding, her eyes looking larger more innocent as her ebony hair shimmered. As Doris now became a Fteshman the teens body appeared coltish. Skinny legs, barely flared hips and small B cup breasts concealed by a large tshirt.
Entering grade school on the opposite direction, passing her 14th birthday and becoming 13. Doris paused, her running slowed as she lost a couple inches of height. Glancing at the treadmill, the oddest feeling crept over her like vertigo. Did the treadmills display seem higher?
Although her paced slowed, Doris pressed on. A gentle sinking feeling washing over the girl as she crept closer to 13. Looking at her feet, she furrowed her brow. Doris shoes felt quite a bit looser, while her yoga pants appeared to be sagging and bunching on her.
"What the heck is going on," she exclaimed, gasping at the sound of her voice. Was that her? Her voice sounded so high. Looking at her hands her eyes went wide. They were smaller, daintier, more childish. Hitting the stop button, Doria came to a sudden stop, letting out an audible squeak as her yoga pants lost hold of her narrow hips.
Stepping off the treadmill, Diria was shocked as she almost stepped out if her oversized sneakers. All if her clothing felt wrong. Her tshirt hung past her crotch completely covering her flared curves and softball sized breasts, her yoga pants barely clung to her hips, bunching around her ankles. As she looked in the mirror her jaw dropped as she looked at the round innocent face of a child about to enter her teens. Quickly looking at the display, Doris felt her heart skip a beat.
"12 years 11 months," she whispered. Looking back at her reflection she could see a preteen version of herself staring back. Sandy hadn't been kidding about the gym, now she just needed to figure out how to change back.
