Pierce decided to buy one of the water bottles that he saw, as he was always losing his. He also seriously doubted that any of these objects actually had magical powers, and if they did, why would they exist in a water bottle? Pierce walked back to that aisle and picked the first water bottle he saw, a really big one that looked like one that would be hard to lose. Pierce then walked back to the door with water bottle in tow.
Pierce decided that he might as well as see how mush water the bottle could hold, so he filled it up with some water from his sink. Annoyingly, it only had water flowing into it for about a second before it started overflowing.
Pierce sighed and put on its cap. He didn't want to waste water, so he drank the water before he put it into the dishwasher. He then noticed that he was no longer thirsty. He had originally been very thirsty, which he attributed to being in the store for hours. But now his throat didn't feel parched!
Pierce smiled, happy that the water bottle was slightly magic, and walked back to his room. He looked at the clock and saw that it was 10:00 PM, which was why the house seemed so empty. However, he was tired, so he got into his pajamas and went to bed.
The next morning, Pierce woke feeling very sore to his mom shaking him awake to get ready for school. "Paige, get up. You have a presentation today and you have to look good!" Pierce opened his eyes and sat up. His mom walked out his door, satisfied that he was awake, and then Pierce realized what his mom had said. She had called him Paige.
Pierce jolted upright and looked in the mirror. Looking back at him was a small, brunette girl with long hair, medium-sized breasts, and a tiny waist. Pierce looked around his room and realized that he was now a she, and her possessions had changed to reflect this.
Suddenly, a wave of memories hit her and suddenly she remembered both of her lives, as Paige and as Pierce. Apparently, she had turned into a girl by drinking the water bottle's water. However, the water bottle had also given her an advanced intelligence. Paige knew that she would turn back into Pierce at midnight, and that every night at midnight after that, she would transform from body to body, swapping Pierce's and Paige's lives. She also knew that whenever she wasn't in a body, the memories of people that existed when she wasn't that person would be of her or him being perfect.
Paige smiled and realized that this dual life was perfect: an advanced intelligence, two bodies who were perfect when she wasn't in them, and a sexy body when she was in one of them.
