A tiny brunette infant, maybe a year old, was now crawling towards Isaac. Gazing down the hall Isaac could see clothing haphazardly discarded.
"Sarah," he whispered.
Sarah looked up at Isaac the infant babbling at him. Sarah now frowned, her face contorting in rage as she realized she was too young to talk.
"Okay just hang on a sec,: he said quickly. Scooping the tiny infant up, Isaac now wrapped her in his lab coat as he raced towards the lab. Sarah could only watch, her body so small and weak that she felt helpless in her friends arms.
As Isaac now sped towards the lab, he felt an odd sensation. Was Sarah getting heavier? At first alarmed that the girl might be infectious and was altering his age, he looked at the small infant, his eyes growing wide.
Sarah now looked closer to 3 and was racing towards 4. The infants face was maturing, her body losing baby fat as she grew. "Isaac what's going on," she asked in alarm.
"I think your growing up," Isaac answered, stunned to see the girl now become a kindergartner of 5. "Your starting to get kinda heavy."
"Are you calling me fat," Sarah said incredulously as she became 6.
"N..no," Isaac stammered. "No, uh, it's just, um your getting bigger." Placing the girl down, Sarah wrapped Isaac's coat around her as she gazed around the facility in wonder.
The spy was now 7, still just a child. Looking around she couldnt believe how big everything seemed. Isaac's lab coat completely covered the girl at this point, yet she could tell that wouldnt be much longer. As she became 8 she could see her toes beginning to poke out from underneath the jacket.
Isaac and Sarah said nothing as they continued to gawk at one another. Sarah was growing up again. Isaac felt as if he was watching a movie in fast forward. The girl was reliv9ng growth spurts, puberty, as she once more reached her full height she clutched the increasingly small coat around her.
"Can you find me something to wear,: she said meekly as she celebrated her 16th birthday once again. "I'm feeling real weird being a naked teenager in the middle of the lab."
"I have a medical gown in the lab,: Isaac replied sheepishly. Seeing little recourse, Sarah now followed her old friend to his lab.
Finding a gown, Isaac offered the teenage spy some privacy as she changed. As she finished dressing she called Isaac to come back in. Isaac returned, blushing fiercely as he gazed at an 18 yr old Sarah, dressed only in a medical gown.
"Whoa," Isaac whispered.
"Focus casanova " Sarah exclaimed, the 18 yr old brunette trying to sound as authoritative as possible. "What happened? How did I go from teen to infant and back again?"
"I'm going to have to run some tests Sarah,: he said, blushing fiercely as Sarah went from 18 to 19. "Why dont you just lay down so I can examine you."
Sarah gazed at her old friend seeing how flustered Isaac was. Obviously the bookwormish man was smitten by her youthful body. Laying down as seductively as possible she now looked Isaac in the eye giving him a lusty work. "What ever you say doctor," she purred, watching Isaac gulp.
"Do you really have to do that," Isaac groaned, blushing crimson. Sarah simply laughed as Isaac now began his examination.
By the time Isaac had completed Jo's examination, Sarah found herself once more at 35. Although still nude under her hospital gown, she at least didnt feel the kind of embarrassment at being naked like she had when she was younger. Unfortunately for Isaac, he only seemed more flustered as Sarah got older. "So what do the results say?"
Isaac's eyes went wide as he gazed at Sarah's test results. "This is incredible," he whispered. "It appears your cells have absorbed the temporal energy from the both allowing you to alter your physical maturity."
Sarah simply sighed, giving Isaac the look she would often give him whenever his explanation were too complicated.
"Sorry," he said sheepishly. "The results say you can alter your physical age yourself. You can age shift now."
"Age shift," Sarah asked. "How? What causes it?"
Isaac sighed as he now told Sarah how she could activate this new found power.
