Marcus sauntered down the street, feeling on top of the world. At twenty, he was quite attractive, featuring a well-proportioned face, muscled body, and a luxurious tan. He was wearing a faded pair of jeans, a tight-fitting white shirt, and a pair of sunglasses he thought made him look rather sharp. He knew he was irresistable, he saw the hot college girl checking him out as he passed by her on the sidewalk. Unfortunately for her, his affections belonged to another. But that isn't important right now.
Running his hands through his thick, windswept hair, Marcus moved his hand down to check on his stubble. He had been trying to grow it out to achieve a certain look, and was a little agitated to note that it hadn't thickened at all today. On top of that, his shirt didn't seem to be pressing up against his pectorals as much as he was used to. He straightened the shirt out a bit, hoping that would fix it.
What Marcus didn't notice while he was busy fooling with his shirt was that his stubble was not growing like he hoped, but fading away. It vanished almost completely in the course of a few moment's walk, leaving a faint fuzz on his lip and chin. He also didn't notice his clothing growing looser as he waltzed down the street.
"Grr..." Marcus growled as he lifted up his pants. They had begun to slip down as he walked, which was unusual. As he looked down to see what the problem was, his glasses slipped down the bridge of his nose. He angrily shoved them back up, and continued walking.
Marcus's shirt was in no way tight-fitting now, as all the muscles that used to inhabit it had shrunken to their sixteen-year-old size. His pants continued to slip down his legs, and his sunglasses also had difficulty finding purchase on his rapidly dematuring face.
"Wha..." Marcus said, observing the slackened nature of his shirt. He went to feel the shirt, and finally noticed his thinned physique. He snapped his gaze down so fast his glasses were flung off his face, but he caught them before they hit the ground. What he saw frightened him. He saw a shirt, moments ago tight-fitting on his muscular frame, hanging sadly on his skinny fourteen-year-old frame.
Marcus yelped, his voice slipping to a high pitch at the end of the yelp. He had shortened noticeably by now, the legs of his pants were bunched up at his feet. Having been sliding down his legs for a few moments, Marcus's pants finally fell completely off, revealing smooth shins. Alarmed, Marcus tried to back up, as if that would save him from this horror. He only succeeded in completely stepping out of his too-large sandals, losing his balance and falling on his behind.
Continuing to youthen, Marcus quickly slipped past puberty while sitting on the ground, shocked. His limbs thinned, his face regained a boyish appearance, leaving him a skinny little kid sitting on the sidewalk pathetically.
But the process wasn't yet finished. He shrunk even more, heading into early gradeschool years. His cheeks fattened, leaving him a truly childish look. His overlarge shirt washed over him, becoming like a giant tent over his youthful frame.
Soon it was over. Marcus was left a child, five years old at most, sitting on his old shirt like a picnic blanket, wearing only the swimming trunks he had underneath his pants. He stood up unsteadily, holding his shorts (which now fit him like pants). Looking around unsurely, he soon took off running, crying at a childish pitch.
Dr. Augustus looked at the weeping child, who had a minute ago been a confident young man. He then looked to the bulky device in his hands and smiled. He would have fun with this later, but first the child...
Where does little Marcus run?
