Down to size

You quickly swipe a slider to the left labeled “Height”, and as your sister continues to make her way towards you the space between you seems to grow wider and wider. Her neck starts to crane up as the indignant look on her face gradually becomes one of confusion.

By the time she reaches you, you tower over her, your gleeful face looming above her tiny form. She looks around herself to gather her bearings, but you ignore her confusion and pick her up in one hand. She lets out a shriek as the floor falls away from her into the distance and you bring her to eye level.

The app had made her smaller, all right. You estimate that she now stands at a diminutive 6 inches tall. Her clothes remained proportional to her new size, so she’s still wearing the blue-green crop top and the cyan miniskirt that she was before, only now in miniature.

She squirms in your grip, trying to work her way out of your hand, but her weak little arms can’t even budge one of your fingers. Where wriggling reminds you of fondling your own cock… come to think of it, she’s about as tall as your dick now.
