Like many kids, Jack has a particularly annoying relative. In case, his older cousin Gus. Jack and Gus has a bit of a complex relationship: Jack would fetch stuff that Gus asked for and Gus wouldn't smack him around. Sadly for Jack, he still hasn't grown big enough to stand up to his cousin. Telling his parents wouldn't do much good because Gus would go right around to picking on Jack, adding a bit more punishment for tattling.
This day, Jack and Gus were at the mall. Before long, Gus said, "I'm thirsty. Jack, go get me some green tea."
"Are you going to at least give me money for it?" asked Jack.
"You have your own money," said Gus.
"Are you going to pay me back?" asked Jack, not really expecting any.
"If the green tea is good, I might consider it," said Gus, which could probably be translated to 'ain't gonna happen'.
Jack sighed before walking off. He wasn't even sure where to find some green tea. He wasn't even paying attention when he walked into the shop. He spotted the cans of green tea-flavored soda in the fridge and grabbed a can. Gus probably wouldn't care if it was a soda instead of actual tea. He actually might prefer it.
The old man at the register asked, "Are you getting that for yourself?"
"No, it's for my stupid cousin," said Jack with annoyance.
"Ah. I suggest you have a sip of that before you give it to your cousin," said the old ma, "After all, it's your money, you should have the first taste."
"Sure," muttered Jack in an uncommitted tone. He walked out of the store with his purchase. He was heading back to where Gus was when he thought about the old man's words. Why shouldn't Jack have the first taste? It's not like Gus is going to pay him back for the drink. Popping the tab, Jack took a sip. Hmm...tasty. Personally, Jack would have preferred raspberry, but it wasn't bad.
Just then, Jack felt a strange gurgle in his stomach. He quickly headed for the restrooms, but before he could enter one, the sensation overcame him. Jack gave a small groan he felt his flesh reshaping over his bones. His bones were also changing, becoming longer in some areas, shorter in others, but thinner overall. Jack gave an involuntary grunt as his manhood inverted itself with a squelch, his pelvic area hollowing out for a new set of organs. To emphasize the changes even further, his chest started pushing out into twin mounds that soon became impossible to ignore. Among these changes, Jack also noticed that his skin was changing colors, going from normal pink to a honeyed bronze. His longer hair was still black, but acquired more of a sheen than before.
When the changes stopped, Jack instinctively knew what happened to her. She went into the women's restroom and confirmed it. Instead of a teenage boy staring back, she saw a gorgeous young woman in the mirror. Her boy's clothes didn't hang perfectly on her new body, but it didn't do anything to hide how curvy she was now. The more surprising part was how Asian she looked. From her skintone to her almond-shaped eyes, there was no doubt she looked like she had Chinese blood. Or maybe it was Japanese, she couldn't really tell.
It didn't take a genius to figure how Jack was changed. She looked at the can of green tea soda. She hadn't noticed the 'TG' on it before. She wondered if she should let Gus have this soda despite what it's done to her. But then a more mischievous thought came to her. There was no way Gus would be able to tell who she really was unless she told him. It would probably blow his mind to have a sexy Asian woman flirt with him and the expression on his face when he found out she was afterwards would be priceless. But then, since Jack was a woman now, she could probably do her own thing now. Her changed body could use better clothes than what she was wearing now.
