She can't take it

Hanna squirms slightly, no longer able to walk through the crowds as the itch continues to get worse. Her entire body seems to be tingling, and she throws one hand up the back of her shirt, while the other works at her stomach.

You give her a tiny nudge with your power, and the only thing in her mind is the itch, no longer even thinking of the crowds of people around her. In one swift movement she grabbed the hem of her shirt, pulling it up and over her head, her now bare breasts bouncing into view.

A number of people gasp as they watch her toss her shirt to the floor, itching at her exposed shoulders, arching her back as she did so, pressing her breasts up and outwards, giving everyone a full view.
