It was the Holiday season at the Tendou Dojo and Ranma Saotome was asked to help with the Christmas decorations.
"Ah, come on, do I really gotta waste time on this?" Ranma yelled. He didn't see anyone else being asked to do it. Why did he have to decorate the house on his own?
Much to his annoyance, he was just given some money and forced into town to buy some decorations. As much as he didn't want to do this, it seemed he had no choice. Though, it's not like he knew any stores that sold Christmas stuff.
As he passed by the Cat Cafe however, he saw that the owner of the shops granddaughter, Shampoo was pouring a strange liquid everywhere. Ranma wouldn't have thought anything of it, but then Christmas decorations appeared exactly where the liquid was poured.
"Hey Shampoo! What's that stuff ya got there?"
"Hm?" Shampoo turned around. "Oh, hi Ranma. Grandma made an Instant-Decoration potion to get ready for the holidays."
"Oh, wow!" This stuff would make his job much easier. "Think I could get some of that?"
Shampoo thought for a minute. "Well, I do have about half a bottle left. I could give the rest, for a kiss."
"Ah come on, can't I just pay ya for it?" He figured she'd try something like this.
"Nope, kiss or nothing."
Ranma rolled his eyes. "Ah, alright. I guess I'll just-" He quickly kicked the potion out of Shampoo's hand and into the air, swiftly jumping up to grab it before running towards home.
"Hey! Ranma!" Shampoo yelled. She was about to give chase, but her grandma shouted at her to get in and help with customers.
As soon as Ranma was back at the dojo, he wasted no time in pouring the magical liquid onto the roof of the house. Watching as the snow that was on the roof transformed into green and red lights.
"Ah yeah! This stuff is awesome!" Ranma looked around the yard. "What do I use it on next though?"
He stood there, next to a window that lead into his fiance, Akane Tendou's room. She opened the window, "What are you doing?"
"Hm? Just putting some decorations up like I was asked."
"What's that bottle for?"
"Wha-" Ranma put the bottle behind his back. "Nothing."
"Show me, I wanna see!" Akane stepped out onto the roof. Ranma stepped back trying to keep her from seeing it, unfortunately he misjudged how far from the edge of the roof he was and ended up slipping off. Instinctively he was able to grab onto the side, as he was hanging there though, Akane was able to grab the potion from him.
"Instant decoration? Really Ranma, you can't even decorate the house without some kind of magic solution."
"I don't need your lectures tomboy. Give it back!"
"My lectures!?" She looked at the potion. "Fine, you want it?" She uncorked the potion and then poured it onto Ranma. "There, enjoy it!"
Ranma yelled in surprise. The cool water from the potion, caused him to switch to his girl form, before she slipped off the roof, landing on her ass. "Ow! Akane you jerk!"
Akane ignored her cries, and went back into her room before slamming her window shut.
Ranma checked the bottle. It was completely empty. "I wonder if Shampoo has anymore on her." At this point she was willing to kiss Shampoo for some more.
She stood up from the snowy ground. But as she tried to walk away, she realized she wasn't able to move. "What the-" The snow must've been deeper than she thought. She looked down at her feet. Her feet weren't there though. Her legs were instead connected to some kind of large cylinder.
"H-Hey! What's going on!?" She didn't know what to think of this. It must be the potions doing. She didn't consider what it would do to a person.
That's when she felt an odd sensation coming from her butt and legs. Ranma watched as her thighs fused together. She could feel her butt ballooning outward as well. Expanding and rounding out with a somewhat embarrassing squeaking noise.
As her ass and thighs grew more and more, she felt her pants squeezing them. The pain from the squeezing was almost unbearable. So much so that it was a relief when she heard them begin to rip.
Of course that relief wouldn't last long, as the realization that her butt was now exposed to the elements and any passerby's was almost too much to bare. Even worse was that her lower half was now nothing more than a large sphere.
Then she felt the same inflated feeling emanating from her torso. She was helpless to do anything about her rapidly growing breasts. They expanded larger and larger, until her shirt could no longer contain them. Her giant tits were now also exposed. Normally she didn't mind her chest being out to the world, but something about how big her boobs were made her feel more exposed than she normally would.
Next her arms started outstretching against her will before bloating out into a long, smooth, pyramid shapes. Her hands dissolved into the pyramids, leaving only 2 of her fingers sticking out from the sides of them. The normal light colored skin of her arms changed into a brown color. They now resembled big goofy sticks. Ranma finally realized what the potion was doing to her. It was transforming her into a giant inflatable snowman decoration.
Ranma wanted to scream out for help from someone, anyone. But when she attempted to yell out, her mouth didn't open. In fact, it was starting to move against her will. She was forced to make a big cheery smile, making it look like she was enjoying this hell. Her scream coming out as nothing more than a pitiful sounding squeak.
With the transformation done, the stationary Ranma could now only focus on the stinging chill of the outside world on her vinyl skin. A feeling she would be forced feeling all night, if not longer.
That's when she heard someone approaching from over the brick wall. "Ranma!" a familiar feminine sounded.
It was Shampoo. She was saved.
Shampoo walked over to the lewd snowwoman decoration. "Oh, you poured it on yourself. That's not good."
Ranma tried to say something, but all that came out was another pathetic squeaking noise.
Shampoo just shrugged and put a scarf around Ranma's giant neck. "Winter's gonna be cold for you." That was the last thing she said before walking off.
Even with the scarf, the only warmth Ranma could feel came from her cheeks. The humiliation of being reduced to something so helpless finally setting in. The implications of Shampoo's sentence didn't help. Did this mean she would be stuck like this all winter? What if it meant longer? What if she was never turning back!?
All these thoughts permeated Ranma's airhead. She felt afraid. She felt so vulnerable being unable to move out in the snow. The only person that knew what happened to her had just walked away. Even if someone else found her, would they know how to turn her back? What if they just laughed at her inflated body?
There was nothing she could do now but hope that salvation would come. Of course, salvation isn't a guarantee, especially when it comes to magic.
Merry Christmas.
