The DNA inside her cells began to divide at an unprecedented rate.
The operator made a shrill laugh as the child's body began to shake uncontrollably, and she fell to the floor like a rag doll. The orderlies lifted her (already) slightly heavier body and carried her back to her room. They dropped her on the bed and half covered her with a thin blanket, her body shaking with shivers and her face as pale as sheet.
Balancing the semi-conscious little girl on her feet (did she seem taller?), the orderlies stepped back and the operator activated the screen, holding the little girl in place. The patterns and shapes forming the DNA helix of the grade-schooler moved faster than ever, shocking the operator. The 6 year old's eyes sprung open and stared into oblivion, her longer hair blowing back, revealing her tiny features. Sweat soaked her outer gown as the machine held her body rigidly.
The cold air suddenly made her small nipples stand through the soft material of her clothes. The preteen was totally oblivious to what was happening around her. The catatonic state she was in was a side effect from the genetic acceleration the operator had put her through.
The now 8 year old's chest, still as flat as a board, began to move forward, nipples appearing as though they were being cupped. Standing firm against the gown, the movement began to stretch the fabric. Bulges widened and vanished again.
With increasing speed, the gown became taut between the two small but hard nipples as her 9 year old chest thrust out and bent backwards.
Her upper body and chest widened until suddenly a small rip formed along the stretch. Her breasts hadn't begun to grow yet, but her chest bulged and flattened in a strange way. The orderlies ran away with fear, leaving the operator to watch the wondrous transformation he had created. He realized that her breasts would soon swell with impossible speed. Through the tear, he saw the still undefined flesh of her chest. The operator grinned to himself as the little girl's breasts briefly seemed to bud and vanished again.
The 11 year old girl's bosom then began growing in earnest, but she remained held tight by the machine. The metal banged with the force of her growth. The operator laughed heartily as he returned to the console. The little girl watched the operator with her wide eyes. The operator, fully excited by his ability to control human DNA, rushed his next commands. A moan came from the little girl as her aging accelerated. Looking up, the operator watched as the little girl grew several months older in seconds.
Slowly the girl's scream died down, her newly developing chest heaved up and down as she breathed deeply. The young little girl's trousers that hung loosely on her legs had filled up and looked almost painted on, denim straining at the seams. The operator realized the process couldn't be stopped.
Her shirt top had risen up her body, revealing her pale trim stomach. The machine's mechanical restraints brought the little girl's arms up, putting her into the iron cross formation. On her sleeves the first tear appeared, and her stomach was much longer. Her A-cup breasts lifted slightly as the girl's arms lengthened against the hard metal restraints.
The operator looked from the top of the little girl to her feet and what he saw amazed him.
The girl's clenching, stretching feet broke through her overstrained shoes in moments, torn leather pieces flying in all directions. Her feet were covered in veins which faded out as they reached her calves. Her straining trousers had lifted up as her still slim legs had grown another inch, but the rise stopped at the calves. Tears suddenly appeared in the hem of the trouser legs as the material gave way.
Sliding out of the denim, the lower legs of the now 12 year old girl grew at an accelerated rate beyond the confines of her trouser legs. Further rips up her legs exposed the slight swell of her thighs which continued to grow unabated by the fabric.
The sweat created by the now preteen's body began to soak the material of her incredibly tight shirt. The shredded pants finally fell away in 4 big pieces, leaving the girl with some insanely tight underwear. The increasing curves made the underwear look like a thong. A big tearing sound made the operator look up at the 13 year old's arms, which had become too wide for her sleeves, very quickly her slight muscles and bones expanded beyond what the sleeves could hold.
Like her trousers, her growth removed her sleeves, exposing her upper arms.
Her slowly rising torso ripped and shredded part of the shirt top, revealing her now longer body. The next aging spurt expanded the girl's body in such a way that the top became like a sports bra, incredibly tight and small against the almost womanly chest of the 14 year old girl.
He would never forget how the thick titanium restraining bars holding the teen began to bend like rubber against her widening body. The cold air in the room made her nipples expand further until they ripped through the thin undershirt.
The final twist the genetic programming put on the 15 year old girl was to extend her short, red hair into long shiny healthy locks, which fell down across her broadening shoulders.
With the age progression almost complete, the machine could no longer confine the girl in her iron cross formation. The metal bars tore with a demonic screech and crashed to the floor with a deafening clatter, denting the concrete in many places.
Her arms trembled from her shoulders. Her waist seemed small against her chest. Her legs looked much thicker, her fully exposed, very round breasts rose and fell as the accelerated aging subsided. The operator looked at the newly created teenager with pleasure.
From a pale little girl, he had created a perfectly normal woman. Unaided, the girl stepped from the machine, the remaining orderlies staring uneasily. Standing in front of the operator the girl finally spoke, her voice soft and feminine.
