Dave got home from work and found the strange program in his mail and thought it sounded interesting so he took it and installed it on his computer. He was an average looking guy about 5'7 170lbs. The program needed the system to reboot so he restarted his computer and went to the kitchen for a drink and a snack. While he was in the kitchen the program started up it scanned everything within a 100 foot radius, including Dave's cat Mitsy. Mitsy was startled and jumped up from her usual place beside Dave's computer and landed in the keyboard. option windows opened and closed changing all of the scanned subjects.
Mrs Fuller who lived one floor below was cooking dinner. She was in her 40's and out of shape and didn't notice her breasts and butt lifting and her waist narrowing. Her husband was in for a big surprise because she had gained the legs, butt, stomach and breasts of a 19 year old, the rest of her still remained that of a 40 year old. It was really too bad he wouldn't be able to satisfy her with the penis of a 5 year old.
Janene a girl down the hall who was an aerobics instructor, began to back on the pounds. When she goes to get changed she'd find she wouldn't be fitting into her favorite jeans for a while and all her bra's would be much to small.
A 17 year old girl was lying on her bed in her comfy clothes, a tiny tank top, and fleece shorts. The shorts hugged her tight little shapely ass and the tiny tank top gave no support to her large d cup chest. The ensemble showed her tiny toned waist perfectly. She prattled on to her friend on the phone not noticing her size was decreasing. She was getting younger, her tight clothing was loosening on her diminishing frame. Her breast deflated from their soft globe shape becoming perkier then pointier as they got smaller she was down to a b cup. Her hips narrowed, her ass flattened and her legs shortened transforming her into her preteens. She started to gain some baby fat as the last of her chest receded. and with that her curves were completely erased. The shrinking accelerated as she hit 10 years old, before she could react the phone fell out of her hand as she was swallowed up by her previously skimpy clothing regressing at 2 years per second. She was now a 6 month old baby all she could do was cry. Her mother came in to investigate. Expecting to find her daughter she found a newborn on her daughter's bed, she cradled the baby to calm her. The mother pulled down on her skirt and shirt. Strange they felt tighter and shorter, and even stranger the room looked smaller too. She turned around to walk to the kitchen and found herself ducking as she passed through the door frame it looked much lower.
A 12 year old girl who was fighting with her much bigger 15 year old brother had a growth spurt aging 8 years, while her brother lost a couple inches in height, sending him from 5'7 to 5'2 and her from 5' to 5'8. She stood in her t-shirt and shorts were stretched out by her c-cup breasts and curvaceous shapely ass of her mature adult body. She smiled as she pushed her little brother around easily with her new developed adult muscles.
Tammy had just finished getting ready for her date, she had been waiting for this day for 5 long years. She was finally gonna get even with a Jock from her high school grad class. She had contacted him a week ago and finally got him to agree to meet her. Her door bell rang. She did a mirror check to make sure she was at her best she'd been planning this moment for 5 year, she'd answer the door in the sexiest tiny bikini she could find. With alot of hard work, eating right exercising daily, a little hair dye with extensions and a few thousand dollars in plastic surgery she's attained the perfect body. At 22 years old she was toned, tanned, 5'7 tall, 110lbs, 34, 24, 32 measurements, with large perky D cup breasts, a small tight round ass, and long curly blond that flowed down to her ass. She was far from the awkward, flat chested, overweight and short brown haired teen she was 5 years ago. She adjusted her bikini top for maximum cleavage and she was ready to answer the door. Tammy was just reaching for the door as Mitsy landed on the keyboard. She open the door and looked him up and down, 'Hi Brian,' she said as sexily as she could 'you look amazing' she told him. It was strange he looked just as he did 5 years ago, like he had never aged a bit. he hesitated 'Um yea you look amazing too,' he lied. What the hell she thought to herself. Why isn't he drooling over me? and his compliment didn't sound sincere. She looked down at her chest but instead of finding the $3000 cleavage she had payed for, she saw her bikini cups laying flat over her nipples and a pudgy belly. She shrieked and grabbed at a lock of her hair, it was brown, and her tan was gone. She had gained all her weight back. She went a few steps back into her apartment and looked in her mirror. She looked just as she did on her last day of high school, she looked at Brian who was standing in the doorway. He looked just as he did on the last day of high school too. This had to be a nightmare
Dave was looking in his fridge he was not immune to the changes, and didn't notice as he lost about 5 inches in height.
Mitsy stopped and stared into nothing as knowledge flooded into her brain she gained the intelligence of an above average human. Mitsy look around like she had a new set of eyes, she knew what had happened because she had seen the screen when she gained her intelligence. She had the brain of a human but she was limited in her little form. She tapped on the keys as best she could with her clumsy paws then hit enter and jumped onto the floor.
She began to grow bigger, her long tail got shorter and her hind legs straightened the bigger she got. As her head got bigger her ears spread outward to wards the sides of her head, and her face flattened. Black hair sprouted from the top of her hair and grew longer as she enlarged. Her front paws slowly started to look like hands as he fingers grew in and her fur receded. Her feet grew longer and her calves and knees formed straitening her hind legs. She remained on her hands and knees and stretched, the last piece of her tail receding into her backside. She convulsed slightly a few times as her inner organs changed from feline to human. She was about the size of a toddler, but was growing bigger with every passing second/ when she got to the size of a 12 year old her chest sprouted a couple bumps, they grew to a-cups. and the changes stopped. She was still on all fours and had her head down, she suddenly threw her head back tossing her thick black curls over her shoulders. She sprung to her feet and went right for the computer. She started to type on the keyboard. 'thats better' she thought, 'its much easier to type now.' Some clothing on the floor began to morph. A t-shirt transformed into a woman's tank top, and pair of jeans turned into a pair of tiny denim shorts. She slid the tiny pair of shorts on and put the tank top on. She had a quick look in the mirror. She was now a 21 year old girl, Jet black long curly hair, 5'3, 105lbs, 32A-27-32 with a undeniable beauty. She had retained alot of her feline characteristics, her beauty was one of them.
Just then Dave came back in the room, and jumped when he saw Mitsy. 'What the hell, who are you, how did you get in here?' what was more surprising was that she was taller then him slightly. 'Its me Mitsy,' she said cheerfully with her head cocked to the side inquisitively.
'mitsy?' he repeated. 'My cat's name is Mitsy?' he said in disbelief. 'but how?'
'the computer program, silly,' it changed me and looks like it changed you to.' she said noticing his size. 'I kind of like being bigger than you.' she smiled
