It turns up the heat.

Sweat gathered on Kara's brow as she waited for the effects of the Red Kryptonite to take effect. The thief stood before her shaking, holding the Kryptonite out with one hand. Clearly, like most people, he was only familiar with the green variety, but realized the rock had stopped Supergirl in her tracks, so he kept it out.

More beads of sweat gathered on her face as Kara remained frozen. Nothing was happening. Everything seemed fine, but that only made her more nervous. And sweaty. It was definitely Red Kryptonite. She could feel it yet Supergirl was suffering from no clear effects. She had not transformed or undergone a personally change or any other crazy reaction. She was still just standing there under the hot lights of the museum. Sweating. Wait a minute.

"Damn it's hot!" Supergirl said wiping the sweat from her brow.

"W-what?" The sniveling thief said.

"Aren't museums supposed to- to be cool," Kara continued, pulling on her collar. "I am sweating up a- a storm here."

The thief didn't know what to say. He had expected to have his teeth knocked out by Supergirl, but instead, after desperately taking out a random gem, the superheroine was acting bizarre. She was just standing in front of him with an absent-minded look on her red face, her body slouching in an oddly causal way, and her tone sounding half asleep.

"God, I can't take it anymore." Kara said as she ripped off her cape. "The girls need some air."

And with that Kara Zor-El, one of the most powerful being on earth, pulled off her shirt and threw in on the ground. Exposing her red bra and C cup chest to a random criminal.

"Holy shit," the thief whispered at the wonderous sight.

"Aaaaahhhhh" Kara smiled, "much better."

Kara looked over to the thief only she couldn't really remember who he was or why she was here. All she did know what that even with her shirt off she was still sweating.

"Man, it's not enough," Kara pouted as she fiddled with her skirt, loosening it to the point it fell from her waist and to the ground. "There we go."

The thief's jaw hit the floor. He was seeing Supergirl. Supergirl! In nothing but her red underwear and matching red boot. She could kill him now for all he cared. It would all be worth it.

"Thank you, god," he said to himself. Kara heard him without even needing to use her superhearing but paid him no mind. She was still sweating despite how much skin she was showing. Kara clicked her tongue starting to get annoyed with how unbearably hot it was. The Blonde Heroic bombshell started hovering in the air and one by one unzipped her boots.

"What's up with today." Kara said as she wiggled her boots off her feet. Letting them crash onto the ground. "Hey, did- did you see anything on the news about this, my guy?

"Huh?" The thief yelped not expecting to be spoken to. At this point he had been convinced Supergirl was in her own little world and had no idea anyone else was here. He took the opportunity to tuck the little red rock into his pocket feeling it was something he should hold onto. "Uh, Y-yeah, I think the news reported a massive Heatwave hitting Metropolis. A-and they said we should do whatever's necessary to cool down!"

"Oh- oh that's good to hear." Kara said as she reached behind her back. The thief's eyes went wide, realizing what she was about to do. "Because the shirt wasn't enough, my nips need some real relief. Ya hear?"

And so Supergirl's red bra fluttered to the ground letting her breasts bounce free and exposing her perky pink tits. The thief's brain short-circuited as Kara brushed her hands through her hair with a smile on her face.

"D-d-do what- whatever makes you feel comfortable." He stuttered.

"Far out, man," Kara said as she fanned herself. "You can really take the heat. I mean, it's like a sauna in here, and you haven't even broken a sweat."

"Umm, well, you know," the thief answered, having trouble forming words with Supergirls glistening bare breasts right in front of him. "Good. Insulation?

"Aces. Meanwhile, if I want to stay cool, I need to feel the breeze between my knees."

Kara placed her thumb in the side of her panties and pulled down. Guiding her red underpants down her legs and off her body.

"Haahhhhh, that's the ticket!" The butt ass naked Kara said with an O face you wouldn't believe. She twirled her soaking panties around on her finger for a bit before releasing them. They soared through the air for a second before landing right on the thief's face.

"Whoops, sorry dude." Kara laughed. The thief responding with a collection of gibberish and grunts that sound not to dissimilar from the Tasmanian Devil. He slowly fell backwards, his consciousness fading as he crashed onto the ground.

Kara meanwhile closed her eyes and tried to enjoy the aforementioned breeze. As she floated there, she heard the sound of the AC blasting.

"Oh, they do have one?" The sweat covered hero asked. "Well, I might as well use it then, right?"

The naked Kara flew over to the closest ventilation unit and allowed a torrent of cold air to crash directly into her body.

"There we go, Oh Yeah!" Kara shouted finally getting some real relief. She shifted her altitude and even did a few spins allowing every inch of her burning body a chance to cool off. Her chest, her back, her thighs, her butt, and finally her crotch.

"Oh- oh wow," Kara said, feeling the air blasting right into her cootch. "Oh, yes!"

Kara drank in the euphoria she felt as the cold air vibrated her pussy. She floated closer she opened her legs placing her knees on either side of the vent and began softly moaning in pleasure. Meanwhile the thief finally managed to stand back up and was again gob smacked by what Supergirl was doing. That little red rock had instantly become his most prized possession. He reached into pocket, bewildered it has taken him this long to consider snapping some picks, but before he could he was distracted by the distant sound of police sirens. The cops were on their way.

The thief looked back at the naked Supergirl, who had thrown her head back and looked like she was about to start masturbating. On his way out he saw the Kryptonians discarded clothes on the ground and decided to scoop them up, just in case she came to her senses after he left. He took one more look at Kara bare backside and smiled to himself before escaping out the window.
