Karin floated to the ground, deciding to walk through the small clearing to something she saw in the distance. It was bright and metal, so out of place in the forest it caught her eye immediately. As she approached, her stride quickened so that her flaccid cock began to swing between her legs.
It was a truck, filled to the brim with bottles of bright purple soda pop. Now the oddest thing was, Karin immediately noticed how undamaged the truck was. Sure it had hit a tree, but it could have easily been backed up and taken back to the main roads. And there was a lack of an injured driver, though of course Karin was happy for that.
What the Gardevoir didn't know, and really had no hope of guessing, was that this truck had been crashed out here on purpose. After a scandal involving "Don Pop's Extra-Fizzy Grape Soda", the CEO of the company had to get rid of a lot of tainted, experimental soda, and one truck had chosen to drop it's load here. The soda had strange side effects, but Karin had no idea of this.
She wouldn't have cared anyway. Soda was such a rare treat in her domain that she immediately hopped in the back and snatched up an undamaged bottle, using her psychic powers to unscrew it, and knocking back half the bottle.
"*URP*!" Karin burped, "Oh my, excuse m-"
*BRRRAAAAAAAP*
Her second belch was so loud that it echoed across the metal walls of the truck and came out the other end amplified, shaking the leaves on a few trees behind her. She stood wide-eyed for a minute, before swigging down the rest of her bottle and letting out an equally nasty burp. Karin grabbed two more bottles and laid back on one of the crates, pouring the fizzy brew from both into her mouth, spilling it all over her cheeks and chest. She was really loving the acoustics in here, the belching sounded too perfect.
*BUUUUAAAAAAAAARP*
She felt the truck shaking, and giggled. Of course, she still had no idea that this was highly dangerous, experimental soda. And as she guzzled, she started to change.
