A cloud of itching powder

...a cloud of itching powder. Still moving at hyperspeed from her long journey through the spinning tunnel, Rocketgirl tumbled through the powder-filled air. Not immediately sure what it was, she panicked as she inhaled the stuff and coughed it up. The powder coated her entire uniform-clad body. She landed on a padded floor and began trying to brush the powder off herself, to no avail.

"Welcome to the next room in my funhouse, Rocketgirl," Ms Jensen's echoing voice taunted. "As you can see, I've filled the room with a special itching powder of my very own unique design."

Itching powder? Rocketgirl thought. But it doesn't itch!

"Perhaps you've noticed one of the features unique to my itching powder: it doesn't work on human skin. Not directly, anyway. But you may soon notice how it does work. By my calculations, it should have impregnated your supersuit in three...two...one..."

"OHHH MY GOD!!" Rocketgirl yelped. She began frantically scratching her arms, her legs, her breasts, her back. She tore the mask from her itching face, relieved that it stopped itching the instant she removed the mask.

"Wow, very quick to reveal your secret identity there," Ms Jensen teased her. "I'll give you the benefit of the doubt and say it's because you know I already know who you are. Can't imagine you giving up your mask so easily if any other adversary did this to you."

Rocketgirl tried scratching her itching pussy, but quickly tried to put that sensation behind her as her fingers caused her to become mildly aroused on top of the itching. She then scratched so hard at her arms that her uniform sleeves began to tear.

"And now I think you're beginning to get the right idea," Ms Jensen said. "Want to make that itch go away? Scratching alone won't do the trick. But think how good your face feels without that itchy mask on it. Maybe it's time to take off the rest of that uniform."

"No!" Rocketgirl screamed back. "Never! I won't give you the satisfaction of watching me debase myself."

"We'll see about that," Ms Jensen replied. "I give you five minutes, tops. All my test subjects went clinically insane after only three minutes."

Ms Jensen's threat hung in the air as Rocketgirl found herself so distracted by scratching that she could think of nothing else. After a minute, she realized she hadn't even moved from the spot where she landed on the floor. She looked up to try to get her bearings, but her eyes were unable to focus.

After three minutes, Ms Jensen spoke again. "You've managed to outlast all my test subjects. But do you really think you can hold out forever? Don't you feel distracted and weak already? Spending all your energy on scratching an itch that will never cease. Never, unless you do one simple thing: take off your uniform. It's just you and me. I've already seen it all, babe. Is it worth losing your mind to preserve your dignity when you have no dignity with me anyway?"

Rocketgirl knew Ms Jensen was right. She had to focus on winning this ridiculous funhouse challenge. She couldn't do that if she just stayed here scratching herself to ****. With a mighty roar of anger, Rocketgirl tore the uniform from her body, throwing its shredded remains to the ground.

"Excellent," Ms Jensen commented. Fans dissipated the remaining itching powder from the room and for the first time, Rocketgirl could see her surroundings clearly.

The room itself was bare. At the far wall were two open doorways. Above each was a sign. The one on the left said, "Be someone." The one on the right said, "Be yourself." Whatever was on the other side was shrouded in darkness. Taking a deep breath, Rocketgirl knew her next move.
