[REQUEST] A five panel strip (details inside)

Panel 1: A boy in his early teens looks down at his little sister from 5-10 yo., smiling at her (almost with smug), as the sister looks up with a blank facial expression. The sister is up to the height of his waist.

Panel 2: The boy shrinks, and suddenly, the sister is at his chest height. The boy looks confused, while the girl is surprised.

Panel 3: The boy continues shrinking, where he and his sister are now face to face. The boy is looking worried, while the sister still looks surprised, but with a smile on her face now.

Panel 4: The boy once again shrinks, dropping how to his sister's chest height. He is panicking, while the sister is now giggling.

Panel 5: The boy finally stops shrinking, at the height of his sister's waist. The boy is looking very scared (almost using his facial expression to bargain his safety). The girl has her hands on her hips, looking down with a triumphant smile on her face.

Not sure if that's a bit too much detail, but would otherwise, be much appreciated :3
