After several hours of changing clothes, fashion shows, fashion shoots, and other embarrassing adventures, Zach was ready to change back.
"Okay, Sid. You have had your fun. It's time to change me back, " said Zach.
Sid sighed. "Okay. You have been a good sport. I never intended to keep you this way, anyway. How would I explain it to Mom and Dad? But admit it - you did have a little fun."
Zach blushed. "Yeah, it was interesting. Maybe we can even try it again some time. But I am tired, and I want to go to bed."
Sid smiled. "Sure, I understand."
She looked at the phone with surprise.
"Hey, you didn't say it could change other people, " said Sid. She turned the phone so he could see the screen, and her name was now displayed as the subject. "You were holding out on me! You know I hate being short!"
Zach knew it was true. Sid had been short her whole life, always the shortest girl in her class. It had been a sore spot for her, one he often used to tease her when they fought.
"Now, Sid, be careful. That thing is dangerous. I don't think you should use it. I mean, look what happened to me, " said Zach.
"Shut up! Why should I trust you? You had a way to make me tall, and you kept it to yourself? And you think I won't use it on myself, my one chance to be normal, " said Sid angrily.
Sid slid the slider on her height marker, and shot up a few inches. She moaned a little.
"More, " she said softly, and shifted the bar further.
She rapidly shot up several more inches. Zach backed away frightened by the change in his sister.
"More, more, " she continued to moan, sliding the bar further and further.
Her clothes grew tight against her stretching body, revealing a tight stomach and long thighs. The cuffs of her shirt slowly retreated past her wrist, then her elbow, and finally her biceps. Finally, she stopped growing and opened her eyes. She was now taller than the doorframe, and he estimated her to be about 6'4" tall. The same height he had tried to be earlier!
Sid stretched her arms, and looked down at her long legs with excitement. She looked around the room happily, then danced around tapping things that were previously out of reach. Zach hid in the dollhouse for safety, to keep from being crushed by her massive dancing feet. Finally, she plopped down on his bed, and it groaned under her new weight.
Zach emerged from his hiding spot. "Okay, Sid. You have had your fun. No change me back, too."
Side sat up suddenly, and lunged for the phone. She held it protectively against her chest.
"No. You just want to use it to make me small again. Like before. I want to stay this way. At least for a while, " she stood up and walked towards the door. "Besides, I think it is time you felt what it was like to the 'little' sister."
"But Sid, what will Mom and Dad think?" said Zach.
Sid laughed manically. "Your voice is soooo cute. It is like a little mouse. Anyway, I will just tell Mom and Dad I finally had a growth spurt. A really big one. What else are they going to believe? That I used some kind of magical device? That's absurd."
She laughed like a loon. "And as for you ... well, I would just stay out of sight. I doubt Mom and Dad would believe their son was now a talking 12 inch doll. If they see you, they will probably just think they are crazy. And even if they believe you, they can't help you. I have the device! And if you misbehave, I might have to punish you. So just sit back and enjoy your new life. If you are good- I mean, really good - I might let you grow just a little bit taller. Goodnight!"
Sid turned off the lights, and shut the door with a thud. Zach retreated to the dollhouse that Sid had brought out of her closet, and turned on the small battery powered light. He looked at the door to his room sadly. It was much too large for him to open by himself. He was going to have to think of another way out of this mess. Sid was right. His parents would be no help. He was either going to have to do something himself, or maybe rely on the help of a good friend. Of course, maybe Sid would come to her senses and be more reasonable in the morning.
