A young taur walked into a magic shop on a cold autumn afternoon. She called herself a vixentaur, although she had the upper half of a fox, and the lower half of a fox as well with four legs. She smiled at the shopkeeper and gave a friendly wave. "Hey. I'm looking for something for Halloween. Do you have any recommendations?"
The man behind the counter was a fat tanuki, and much older than the foxtaur was. "I swear, that's the only business this shop gets is for Halloween getups and for Christmas. Let me guess, you want something that lasts for a day and then changes you back to your normal self?"
'Wow, that's not rude at all.' The taur thought. "Let's start over. She turned to the counter. "My name is Emily." As she turned to the counter, her tail brushed up against a rack of potions directly behind her. She didn't quite knock any of them over, but she was close.
"Hey! Watch where you're swinging that thing!" The shopkeeper said in a panic. "Those glass jars are very fragile."
"Hm?" Emily turned. She swore she felt her tail brush up against something, as well as the sound of glass clattering, but she didn't hear anything fall. As she turned to get her tail away from the potions, she did so in a manner that her side bumped against a shelf and knocked one potion down. The potion landed on her back and broke open with the sound of a crack and a splash. "Hey!" Even she was amazed how easily the jar broke. It was a fall less than three feet and it just shattered against her soft fur. "Why do you have everything so cramped in here anyways? A two legger can barely shop in here, let alone a taur!"
The shopkeeper shook his head. "That was the...okay, look. I highly advise you to step outside if that potion does what I think it does. I will require you to pay for it, but we shall worry about that 'after' it changes you."
"What does it even do?" Emily felt her body shudder before it suddenly grew in size. She grew up to nine feet tall. The growth to her body was proportionate and just made her look bigger than average. "What the? It's a growth potion?" She was glad she didn't wear pants. Her fur covered up everything down there that it needed to. She had a top, and it already felt tight on her body.
"Yes, and it's a very potent potion! If you don't get out right now you could very well destroy the whole shop, and I do 'not' want that happening."
Emily frowned at the shopkeeper. She felt her body shudder again. She carefully turned her body and rushed to the door just as she grew taller than the shelves in the store. She had to be very careful to control her emotions so her tail didn't knock over anything. The bigger she got though, the harder it was to control. She opened up the door and ducked her way out. As she made it out the door, she had another growth spurt that made her tail big enough that it knocked over more potions, but luckily not onto her.
Emily got outside just in time for her clothes to rip from her growing body. She couldn't believe that she was growing more and more. "He wasn't kidding about potency." She said to herself as she grew to twelve feet, and it was getting worse. She stood on the sidewalk, but she was afraid she was going to get so tall that she'd need to stand on the busy street so she didn't crush anyone by accident.
Emily's body continued to grow and grow. She looked down and noticed the shopkeeper came out and yelled at her, but she grew to 24 feet tall, or over 7 meters, and it made him hard to hear. "What?" Her voice boomed out as she looked down at him worriedly. She tried to keep her body still as she didn't want to crush anything, but she felt something brush up against her paw, which made her step backwards. She could almost feel as her paws created visible craters in the sidewalk underneath her, and she had to put her hand up against a building to help keep her balance. "Man. This...wow." She was at a loss for words. While it was frightening to grow so big, it also felt amazing.
Emily wished she knew when her growth would stop. She was taller than every two-story building, and she was easily getting taller than the seven story ones. The sidewalk was too small for her to keep standing, so she spread out her paws. Not wanting to hit any cars, she placed one set of her legs on one sidewalk, and the other set of legs on the sidewalk directly across the street so that cars would pass underneath her taur body. She looked down and noticed the shopkeeper still there. She bent down and put her hand on the ground with her palm up so the shopkeeper could get on it. She then slowly raised it up in front of her so she could hear. "Now, what were you saying?"
"I'm saying you're going to start paying for those potions you broke now!" The shopkeeper yelled angrily.
Emily felt her body continue to grow larger and larger. She began to tower over most of the buildings in the very city and knew it would be hard to walk around without crushing anything. She didn't want to be rude to the shopkeeper though, and she nodded. "I'm uh...I'm not sure what I can do to pay you back, but I'll do whatever you need me to do."
The shopkeeper rubbed his tanuki hands together. "Oh, I have a job that would be 'perfect' for a taur of your massive height."
A few hours later...
Emily watched her steps as she walked over to a factory. She made sure to walk beside the road to the factory, but not directly on the roads. She retraced her steps as she walked along and made it in short time. To many people, the factory would be hours away. With Emily's new massive height though, hours became minutes, and it saved one could only guess on gas prices. She kneeled down, picked up a large truck with both hands, and delicately carried it over to the potion shop back in the city. It wasn't easy to avoid stepping on things. She'd been lucky not to crush people, but she already crushed a few parked cars with her massive paws.
Still, while she had to be a gentle giant, she helped not only the potion shop, but also other shops that needed deliveries done. She could go from point A to point B in record time, and every delivery was another few dollars to get her back to normal. Unfortunately, her crushing a few cars and destroying some properties with her massive height just added on to her bill from the city, but she didn't mind being a giant. In fact, once she managed to pay off her debt, she wanted to ask the shopkeeper if there was a way for her to shapeshift from her normal size to a giant bigger than the planet itself!
