Sitting in his room, reading one of his many comic books, was Jon's little brother Mikey. Mikey was a typical ten year old, with perhaps a bit too much interest in cartoons and video games, but otherwise fairly unspectacular. He was about 4'6", fairly lanky, with his mother's dark hair and brown eyes. Currently he was wearing a pair of sweatpants and a white t shirt, standard fair for a young boy on a lazy afternoon.
Suddenly Mikey felt the strangest of sensations, as if the room around him was shifting. He set down his comic and glanced around, unable to place that he had spontaneously acquired an additional four inches in height. His clothing had grown to compensate, though his shirt seemed to lag behind, as it started to reveal a big of his midriff.
Suddenly Mikey felt the urge to head down the hall to the master bedroom, and in the short period it took to reach their the boy had seemed to age to fifteen, though he failed to acquire any of the masculine features that should have come with his sudden pubescence. His hair seemed to lengthen a little and take on a stylish pixie cut, the brown hair now taking on a glossy sheen
Mikey absentmindedly brushed his new bangs from his softening features, then paused when he notice his nails were now long and covered in a hot pink nail polish.
"That's strange," Mikey muttered to himself, in a voice that had both matured and gone up in pitch, "When did I get my nails done?" By now Mikey had aged another six years, and had grown another half foot. His limbs were now smooth and slender, his figure almost dainty. His nipples were expanding to a functioning size, and the innermost layer of his shirt peeled off to form a bra for his budding breasts.
Of course, Mikey now recalled, he had gotten his nails done with Linda. The memory seemed clear now, but something still seemed off. His mind just seemed bemused by the idea of thinking of Linda as Linda for some reason. But why was that? After all, he had known his baby sister all her life, and had always had never given Linda so much as a simple nickname.
Mikey shook off the strange feeling, as his body reached twenty seven years and his growth leveled off at 5'8", an inch shorter than his younger sister. By now his face resembled that of his younger sister, though it showed the first hints of a few wrinkles around the eyes and mouth. His body maintained most of its taunt physique, though his thighs and posterior gained a little bit of flesh to them. Mikey was proud to keep most of his figure despite having two teenage children, though that was in large part thanks to becoming a mother so early.
Mikey's clothing hadn't shifted too much with his growing changes, more adapting to his new body than anything else. His shirt had turned into a white camisole, his undergarments became more feminine, and his sweatpants were shifting to keep up with his new legs. A sharp shifting feeling drew Mikey's attention down to his hips, which had repositioned outwardly a good deal.
A smile came to Mikey's lips as he looked down at their childbearing form, remembering how they had saved him a great deal of pain when having his two children. Her deadbeat of a husband had been absent from both their arrivals, but the experience had been a joyful one nevertheless in both cases.
Mikey's reverie distracted him as his plumbing shifted to match his maternal status, and the mother's rapid aging leveled off at thirty three years of age. As the changes completed, Mikaela inspected felt the sudden need to inspect herself. She was an attractive enough woman, never the knockout her baby sister was but still rather fetching with wide hips and a sizable bust. Mikaela had been a bit of a tomboy in her youth, which perhaps helped her raise two kids without much help from their father, which was particularly difficult from such a young age.
Life certainly hadn't been easy on Mikaela, with most of her peers and all her family save Linda shunning her after she got pregnant. To this day she couldn't recall what she had seen in the man who had sired her children, though it must have been something as she had been foolish enough to let him back into her life long enough for her second to be conceived. Not that she regretted for an instant either of her offspring, and in the end things seemed to have worked out just fine, with a steady job as an artist for a comic book firm and her kids living a happy and normal life. And now her sister was visiting for the summer! Linda and Mikaela had had their rough patches over the years, and Mikaela used to worry about her younger sister being little more than just a party girl, but it seems Linda had proven her wrong, and was doing superbly at a respected law school.
Having forgotten what she had gone to her bedroom for, Mikaela returned to her studio, where she picked up some of a book containing the artwork of one of her colleagues and got back to trying to imitate his style.
As Mikaela the thirty three year old comic artist set about her work, the shifts of reality came over another individual, this time one of the children of this new mother...
