My good friend the doctor had discovered a cloning process. She had not only perfected instant human cloning, she had also invented an instant aging method to clone a human to the age when the DNA was taken.
According to the doctor, every year of 'natural' life was akin to only seconds for baby Petra, who grew from fetus to toddler in less than a minute as her body shuffled around an area of 12'x2'x1'. Amazingly, she seemed to be walking in a lying down position, which helped remove the shreds of her baby clothes. Her arms and legs grew along with her hair. Before the second minute, Petra was developing public hair and breasts. Her beautiful chestnut hair had reached her ankles and then blood filled part of the floor; Petra started her period. The doctor said she had already found a way to suppress menstruation in age shifters. You can not imagine the joy of watching a human grow to an adult right in front of you. More than a few times I wept at the miracle I was witnessing. My own little Petra had become a woman.
The next day I left the good doctor and secured a Visa for Petra that would get us safely to the United States. Back home lying in my bed with me was my ideal girl. Without even asking her she would make dinner. Along the way I taught her the joy of poetry and after making love; four times a day, she would write about the emotions associated with our sex.
...Petra 2 was surprised by her first puberty change. She was maturing quickly, her figure was filling out in all directions at once. She gained inches in height, her hair lengthened, her bust expanded like a drawer sliding open under her shirt, and her waist narrowed. Her hips became wide and womanly in seconds, no longer the slender, boyish hips of youth. This caused her pants to explode into slivers of denim. Her nipples darkened and expanded.
She and Petra 3 had been floating in the water earlier, trying to soothe their aching bones that had been growing and shrinking all day. Petra 4 was growing up again. Her shoes popped at once. Arms, ribs, and feet noticeably thickened and stretched in quick bursts, while her hips exploded outwards just as fast as her legs lengthened. Her dress ripped into strips that hung from her waist. Her hair grew at an astounding rate, and even her nipples dramatically pushed out. As she sank to her knees before John's rising cock, she was very much aware of how much she had changed.
Hers was now a classic hour-glass figure, and truth be told, she really did look like a Playboy model. She was probably the same age and of course the same height as Petra 6, and their shoulders were broad yet very womanly. But their backs were dramatically feminine, and the asses that settled over their feet were high and heart shaped. Their chestnut hair had thickened with age and now cascaded over their necks and upper shoulders. Petra 4 slurped John into her mouth, and working with her customary efficiency, she brought him to the brink quickly. She squeezed the base, holding off the inevitable for just a bit while she smiled up at him.
