She has a 'cure'

"Ok," Caitlin said slowly. "If I could make sure you could get dressed, would you come with me?"

"Y-you can do that?" Iris said.

"Theoretically," Caitlin said. "From what we've determined, these... meta-abilities always need a trigger. As you're not bubbling through the floor, I imagine for you it's, ahem, modesty. If you feel like you're not naked, it triggers and whatever inorganic material you touch becomes, well, bubbles."

Iris whimpered to hear it put like that.

"Give me a few minutes," Caitlin said. "Biology's my specialty. A mix of hormones and chemical hypnosis... I think I've got a workaround. Stay there!"

She shut the door; Iris squeaked. Where did she think she was going?!

Iris continued to hug her legs to her chest, unsure of whether or not she should be hopeful. The way Caitlin described it, it sounded... permanent. Like she'd be stuck like this, whatever clothes she wore dissolving as soon as she became aware that she was being covered.

She'd gone through a wall! What could Caitlin possibly have that would-

After far too long, the scientist returned with a syringe and a STAR-labs branded top and skirt. All business, she stepped into the supply closet and shut the door behind her; the naked Iris squeaked, shuffling back.

"Relax," Caitlin said. "This is to help. It'll trick your powers, if my hypothesis is correct. Just stay still."

Iris bit her lip. Well it wasn't like she had any other plans; Caitlin injected it into her upper arm, making Iris wince, then pulled back. Caitlin looked down on her, regarding Iris with a scrutiny that made her hug her legs tighter to her chest.

"Ok," Caitlin said. "Now try these."

She put the clothes down by Iris's feet, then stepped back. Nervously, Iris reached for them.

"C-could you turn around?" Iris said.

"I need to know if it works," Caitlin said.

"I'll tell you!"

"But if it doesn't, if I can see the exact moment your powers trigger..." Caitlin said. "Just put them on."

Iris whimpered. Praying Caitlin was right, she reached for the top first, pulling it on behind her legs and hopefully only giving Caitlin a brief flash of her tits. Then, nervously, she reached for the skirt.

A few seconds later, Iris shrieked; she'd pulled them on, but she could still see her tits, her pussy, everything was still-

"Great!" Caitlin said, beaming down at her. Iris whimpered. againc urling up into a ball.

"It didn't work," iris whimpered. "What's-"

"What do you mean?" Caitlin said.

"I'm still n-naked!" Iris said. "Your.. It didn't.."

"Oh!" Caitlin's eyes widened. "Oh, that's interesting. I suppose it does make sense."

"Wh-what?"

"You're dressed," Caitlin said. "Trust me, I can see it. The formula tricks your body's chemical balance into still feeling as it would if it were naked, though. That's a very basic summary, there's a little experimental work in there, something with applications in mind control- It doesn't matter. What matters is that because you think you're naked, your powers haven't triggered. But you don't need to cover up."

Iris's eyes widened.

"That's your solution?!" Iris said. "To make me always feel as though I'm n-naked?!"

"Well it's better than actually being naked, right?" Caitlin said. "That shot should last a while at least, I can work on improving it, maybe getting it into a pill form, but I'll need you to come with me."

Iris shifted, whimpering. She didn't care what Caitlin said, it still felt like she was stark naked.
