You were her step sibling as it wasn’t easy to watch over her, but it was manageable—until you realized she wasn’t like other kids. She had powers. Powers that let her age-shift and grow to ridiculous sizes, and sometimes, that meant she was a handful.

You’d both went to the mall to buy her bras. But you tried to stay on top of it, doing your best to keep up with her growing needs.

Today, you were at the outdoor mall, walking with her, trying to keep things normal. But as you passed the ice cream shop, her eyes lit up. She stopped in her tracks, grinning from ear to ear.

"I want ice cream, big sib!" she said, bouncing on her toes.

You glanced down at her, trying to stay firm. "Not today, sis. We’ve got stuff to do."

Her smile faltered for a moment, but then her face twisted in a bratty scowl. Before you could react, her body surged upward, muscles expanding as she shot up to a towering 10 feet tall. The people around you started to stare, but you were used to this by now. She crossed her arms, glaring down at you, her voice now deepened by her growth.

"Give me ice cream, sib," she commanded, her tone leaving no room for argument.

You sighed. You knew the routine all too well. Having a sibling like her had its challenges—but you loved her, and you'd do just about anything to keep the peace.
