As Ken headed down the stairs and out of the house, passing Jeff's brothers as he went, he wondered who, if anyone would discover the computer. Deciding he didn't care in the long run, he turned his attention to the upcoming convention and the costume he had for it. Upstairs in Jeff's room, a squirrel, drawn by something inside the room, sat on the windowsill and peered in.
Part of its brain warned of danger, whilst another insisted it could smell something edible inside. Hunger winning out, claws scrabbled over wood as it bounced forward. Leaping on to the desk, it landed on the computer keyboard. A beep from the machine startling the animal, it almost fled. But when no other noise could be heard, it twitched its nose, its tail, stepped across the springy surface, activating more key commands in the process, leapt from the desk, which caused other functions to become active, and moving toward the source of the smell, the squirrel was oblivious to the way the computer screen blinked, flashed several messages, all before scanning the nearest living subject.
Down the block, Ken paused as he felt an almost ticklish sensation come over him. Believing it was because of the excitement of the upcoming convention and what he'd get to wear, he shivered, and put it out of mind. Continuing home, he hurried up to his room. There, he took out his costume, was tempted to try and communicate with Jeff, and instead set it on his bed. Turning away, he headed for his closet where he took a medium size box down from the shelf. Taking out of it a tight leotard which would accent the right areas of the costume, he held it up and asked, "What do you think, Jeff?"
To his surprise, the other didn't say anything. Thinking the other was sulking, Ken grinned and said, "Don't be like that," and when Jeff still didn't say anything, Ken huffed, "Fine, whatever."
Leotard folded back up and stored with a couple other outfits he had, Ken set them and the costume to one side. Leaving the room, he went to prepare for the upcoming convention, as he had to make sure his room was still booked, he knew where to pick up his seven-day pass, as well as the diamond-level pass which, among other things, gave him all-access to events, meet-an-greets, as well as tickets to several of the evening and late-night events, among other details needing his full attention.
Back in Jeff's room, the squirrel finished with what it was eating. Sniffing, it began to explore the room. Detecting things which almost caused it freeze, it leapt back up onto the desk after some time. Racing across the keyboard again, activating more things in the process, the squirrel stopped upon reaching the window. Frozen in place, its fear grew, and wanting to get out, get away, the animal could do nothing as a strange sensation it at first lacked words to describe washed over it. But then, as it began to ken what discomfort meant, among other things, the squirrel unfroze and started to twist and writhe on the desk before rolling off. Lying on the floor, it continued to squirm as first its brain capacity increased, then it started to morph.
The transformation taking no more than a couple minutes, fur regressed, tail shrank and pulled back into the body as ears slid down the side of the head, whilst the biggest change was inside its head. Gaining intelligence, sentience, the squirrel began to understand it was male. But this knowledge was short lived as part of the commands he’d unintentionally given the computer went into play and his squirrel cock and balls shifted. Shrinking, pulling tight against his body, his penis split as his scrotum became a vulva. Testicles forced up into his body, becoming ovaries, the remnants of his dick formed a clitoris, clitoris hood, and urethra opening. The last change his, now her body undergoing was the formation of the rest of internal reproductive organs, the naked, eleven-year-old girl stared in confusion at the room, not sure what happened, nor why she could recall spending the first part of her life as a male squirrel.
