Original chapter by unknown author
Her grin widens as you finish typing. She kneels down, until you have to look down at her. "I used to be smaller." She says, looking up at you. "But then... I grew." She starts standing up, her head rising slowly. "And grew..." she says, her head passing yours. You stand up, so that she still looks shorter. "And GREW..." she stands up faster, her head quickly moving past yours, until she's standing up straight at her normal height. "AND GREW!" She finishes, her head somehow rising higher and higher until her head hits the ceiling.
She looks down at you, and makes up a story as she grows.
"But you see, dear brother..." she says, "I didn't stop there." She reaches up and pushes against the ceiling. "I just kept growing!" She says, a sudden spurt causing her to shoot through the roof. "I wasn't satisfied with just outgrowing the house, though..." you hear her say. You can see her legs swelling larger as she continues to grow. She steps out of the house, a loud booming sound following her footsteps. You wait, wondering what she is doing, when the roof and ceiling are completely torn off by her huge fingers. She reaches in and picks you up, her hand about your height. You see the ground fall beneath you as she picks you up, and you find yourself face to face with her, though she is incredibly huge by now.
"I would have stopped growing, but I liked my tiny tiny brother too much," she says, putting you back on the ground, next to her feet. She lifts a foot up and pokes you with her big toe. "You see, he liked having a gigantic sister." You blush, not having before known that she knew. "So, I thought, why... not... just... get... BIGGER?"
There was a pause, like the calm before the storm, and then your sister started growing. Within moments she had doubled, then tripled in size. Her feet get closer, and her toes are already taller than you. You suddenly notice the typewriter sitting next to you. If you want to do something, now would be the time...
