I got this from a site which I shall not mention due to how it... prostituted Kara later, I found it funny until Kara started whoring herself, which was "ew." It might make me look like a perv but I couldn't resist a nudity embarrassing situation and I do have some limits. If I get accused of plagiarism from the other website, feel free to tell admins to take this down

I do not own Supergirl.

If Kara had known just how adorable Alex could be about it—and Alex was always adorable, but this was another level of adorable, she was practically skipping—she would have insisted that Alex would take her on a tour of her secret government spy workplace a long time ago. That sounded unfeasible, but still, Alex was clearly bursting in excitement to show her everything.

"And this is our kryptonite storage/research chamber." Alex explained.

They entered another chamber, which had the usual DEO set-up: a dense, dark room that reminded Kara a little of a walk-in closet. The narrow walls were lined with shelves filled with containers full of various minerals. Most were green, some red, then blue, yellow, orange… all were encased in clear Lucite cubes that had to be laced with lead, since all Kara felt was a sense of trepidation at having so much anti-Kryptonian radiation around her.

Alex said as much, holding Kara's arm in a friendly manner, while explaining the safety protocols that kept the kryptonite locked away so thoroughly. "You know Superman's had a lot of problems with bad guys who get their hands on this stuff, so part of the DEO's job is to collect it, figure out ways to neutralize it, otherwise study it. We've found some very interesting clean energy applications to some variations of kryptonite." She tapped on a sample of green kryptonite. "It's literally green energy."

"Uh-huh." Kara said, smiling nervously. "You know, I never actually… really thought about what they all do. Superman just told me to stay away from the stuff, I mean, I know green kryptonite weakens me, but what does red do? Just turn you into a lion?"

Alex laughed, picking up a red cube that seemed to glow brighter upon holding it in her hand. "Honestly, red kryptonite doesn't actually have a consistent effect; it depends on changing circumstances how it interacts with Kryptonian physiology and obviously, we can't test it. It may even have some positive benefits for you and Superman, if we could figure out how to apply it."

"Well, bigger boobs would be nice, but I think I'll just stick to the regular kinds of radiation for now." Kara quipped, making Alex laugh.

"A traditionalist. I can respect that." Alex said as she placed box back down on the table. "Hey, do you have your own Bizarro yet? There's actually a whole array of kryptonite that only seems to work on Bizarros…"

Kara wasn't looking at her. She was looking at the cube of Lucite, which Alex had set down just a little on the edge of the table. It was wobbling, about to fall over and Kara reached to catch it, but in her panic she lost control of her strength and slapped the cube away instead of being able to grip it as it flew through the air before it hit the wall. While the sturdy construction of the containment vessel would have been able to handle a fall to the floor, it could not take (effectively) a blow from a Kryptonian with her unrestrained might as Kara knocked the cube into the bulkhead and the lid of the cube smashed open upon hitting the wall before it fell down on the floor, revealing the red kryptonite and without the lead-lined lucite to blot out its radiation, the entire room was covered in crimson red glow.

"Kara, get out of here!" Alex ordered as she turned to Kara, but it was too late.

"Oh!" Kara cried as her and Alex's eyes widened in horror at what was happening next.

Suddenly, Kara felt herself changing—a profound itching sensation all over her body. The fabric at the edges of her suit at her wrists and neckline was glowing ember red, like a battery pressed into steel wool as it began charring off her body, dissolving into ashes as the flames were making their way through her sleeves up her arms along her shoulders and from the neckline down across her torso and back and at the same time she felt the boots and stockings suffering the same fate as Kara felt the cold metal floor pressing against the skin on her feet. While the heat wasn't hurting her physically, it was so intense it was eating away Winn's durable material on her suit as it flared right off her, exposing Kara's bare skin. The fabric was being burned away from the bottom up the feet, heels, ankles and thighs, up her wrists across her arms towards her shoulders from where, alongside her neckline, the glow continued burning the suit, making its way down her neckline and up her waist across her torso, exposing her chest, abdomen and back and as the flames reached her waist and shoulders, the cape and skirt fell off and burned into a sticky molten mess with her boots as well and she also felt the heat of the flames on her underwear as well, sparks going off and tears burning into the straps of the bra on her shoulders and back and the waistband and side wings of her panties at her hips before the lingerie fell off and burned away as well, exposing Kara's breasts, bush and butt, while the tingling heat left her nipples erect and burned all clothing off her skin with no trace left behind. Suddenly naked as the day she was born, Kara placed her bare arm across her chest and put her other hand in between her legs to cover her breasts and womanhood, blushing in utter embarrassment and moaning in dismay and despair at her nudity before she felt the cold breeze of air conditioning against her butt, almost teasingly, as if someone was lightly touching her. Kara wiggled backwards until she pinned herself against a wall and curled to a ball to cover as much of her nudeness as she could, sighing in relief to know that the wall did not burst in flames.

"Oh my God, Kara!" Alex cried, taking off her jacket and offering it to Kara before anyone came to investigate. Almost tearfully grateful, Kara took it but as soon as she put her arms into the sleeves and placed it on her shoulders, she wailed as the itching sensation began again. The zipper of the jacket sparked electrically, while the wool almost exploded with a series of small flames, leaving her butt naked once again. Kara hurried to cover herself again as her new covering burned away and she hid behind a table, the blush on her cheeks more intense than before with her apparently almost unable to cover her nakedness, with only her hands to shield her private and intimate areas. And now she could hear footsteps approaching—the DEO responding to the contamination of one of their hazardous materials.

For lack of anything better to do, Alex stood between Kara and the door, her arms spread wide as a phalanx of DEO Security crammed through the doorway—Kara was sure that Alex's petite body and her own strategically positioned arms weren't doing much to hide her long, bare legs. Feeling eyes on her slender shoulders, something she had never been ashamed of, suddenly made her feel actively self-conscious.

"We have a situation here." Alex said. "Inform Director J'onnz and clear the area."

Alex was, to her credit, amazingly proficient at improvisation. After trying to dress Kara once more in a lab coat and one of the security guards' jackets—to similar fiery ends—she brought some rolling screens down from med-bay, the kind used to separate beds and give patients at least the illusion of privacy. With four of those boxing Kara in, rolled by the admittedly professional guards, they transported Kara to the lab. She still felt overwhelmingly exposed, walking around completely naked, her bare silhouette obvious through the light and flimsy-seeming screens. She kept her arms over her womanhood and cleavage, but that somehow made her feel even more shamefully nude, like people weren't just whispering about her situation, but it was being broadcasted across the globe, cameras covering every inch of her body, people in Bombay able to zoom in on her butt with their tablets.

Finally, her bare feet paraded her into Alex's lab. They left the guards at the door and Alex closed the door, bolted it.

"Don't worry." Alex said. "I've already shut down the security cameras."

Kara blushed fiercely, suddenly aware of the possibility that her nakedness really could've been recorded, broadcasted everywhere, scrutinized like she was some kind of… sex object. Even if Alex would never ever let that happen, the very possibility made her wilt.

"We're just going to run a few tests." Alex said. "And if there's any way to reverse this, we will."

"It doesn't make any sense!" Kara wailed, picking up one of Alex's beakers. "I don't burn up anything I'm holding! I don't leave scorch marks on the ground! I don't understand!"

"It could have something to do with how your mind processes stimuli. Wearing clothes is a fairly recent development for us, evolutionally speaking. It seems natural to us because we're raised that way, but you know how dogs and cats hate being dressed up. With the Red-K radiation playing havoc with your bodily functions, it could be that this has triggered an immune response to what your body now registers as an attack, treating any article of clothing on your skin as hostile and instinctively attacking it. This could be some latent superpower—a vestigial Kryptonian defense mechanism for use against predators that's now reemerged."

"So I can't put anything on if I think of it as clothing?" Kara asked, agape.

"If you think of it as hiding your nudity, yes. Your skin will… have that reaction. It really is amazing how this mutation seems to have short-circuited your conscious response to the tactile stimuli of clothing, skipping straight to some genetic instinct. I don't think it'd be possible with a human."

Kara pried her hands away from her private areas to run them through her hair. "How will I go to work? How will I fight crime? I can't do anything like this!"

"Well, with Superman, we've noticed that the red kryptonite effects tend to last 24 hours. Something to do with the circadian rhythm. Just call in sick to work." Alex suggested. "You wouldn't even by lying—"

Kara scoffed and laughed humorlessly. "Call in sick? Have you ever met Cat Grant?"

"OK, OK—" Alex put her arms on Kara's arms to calm her down, momentarily thinking better of it in Kara's current condition, before Kara gave her a piteous look—like if Alex took her hands away, it really would be too much; she had just throw herself on the floor and wait there until the Red K wore off. "There is a disaster scenario where a hostile actor uses red kryptonite to disable Superman, and while he's affected, stages a terrorist attack or major crime. With that in mind, STAR Labs was working on a contingency plan to counteract the effects of Red K radiation. We confiscated it. They never got it to work right, but I could take a look at it—"

"Oh please!" Kara begged, putting her hands on Alex's arms in turn. "Oh please, please, please—" She felt better just knowing there was hope, a possibility for her big sister to swoop in to save her, and giddily she bounced up and down like they were having a sleepover again and she was trying to draw Alex into jumping on the bed.

"Uh, Kara?" Alex said awkwardly. "That's a little different since you got breasts. And nudity."

"Sorry." Kara said, drawing Alex into a hug, then pulling away from her. "Sorry!"

Alex found some towels for her before looking for the machine. Kara couldn't wrap them around herself without setting off her skin-burning power. She tried to drape one over her butt and hold the other in front of her full frontal nudity, that way she at least felt better about being a nudist camp of one. More like she was posing for Vogue or something. She imagined a tasteful but intimate photoshoot that maybe showed a little of her butt or something. That wasn't so bad.

"Alright." Alex said, wheeling the machine in: it looked like an overhead projector that could also play Xbox One games. "Now, they never got a chance to test this, but I looked over all their notes and it should work just fine. Uh, as long as you haven't eaten radishes in the last four hours. Have you?"

"I would've remembered." Kara said certainly.

"Alright then." Alex dropped her hands from the cart's push-bar, instead kneading them together in worry. It was a gesture Kara well-remembered from their mother. "Are you sure you want to do this? It'll wear off in a day anyway; Cat Grant will understand. We can fake a car accident or something, say you were in a medically induced coma—"

"And what if some alien goes on a rampage?" Kara asked. "Or Livewire escapes or there's a tornado?"

"Then we can use the machine then."

"And waste time that I could spend flying there and saving people? No, we get this handled now, keep me at a 100% peak performance."

"OK." Alex said. "Let's get started then."

In the testing chamber, she insisted on spot-checking all the components, practically taking the machine apart and putting it back together before she would turn it down. Then, after one last try to talk Kara out of it where Kara just had to put her foot down, she retreated to the bunker, leaving Kara alone in the dubious blast pit.

Kara knew they had tested weaponry and rocket engines in there—it still didn't make her feel too good about all the scorch marks on the sandy ground or concrete walls. Nor did having to set aside her towels so they wouldn't interfere in the procedure, making her stand there completely naked. She took a little comfort in knowing that Alex would absolutely positively not let anyone anywhere near her while she was afflicted.

"Ready?" Alex asked over the loudspeaker.

Kara gave a thumbs up to the reinforced Plexiglas of the bunker, knowing Alex was behind it with safety goggles over her eyes—and feeling a momentary flicker of doubt that maybe there were other people with her, seeing her naked. Kara resisted the urge to cover her breasts with her arms, not wanting to give Alex the impression she doubted her.

"Is there something wrong with it?" Kara asked a few moments later. The door to the bunker opened and Alex emerged, safety goggles down around her neck.

"We used it. You didn't feel anything? Well, we got you with plenty of zeta particles, so—" She held out a fresh lab coat. It was the whitest white Kara had ever seen.

"I want to wear that more than I wanted that Mano Belkin dress for prom!"

"Try it on!" Alex cheered, goofily going along with the farce that it was some high fashion outfit.

Posing playfully, Kara played her arms through the sleeves, then struck a gallantly chic stance—only to feel an itching all over her body as the lab coat burned right off her, leaving her nude again.

"That can't be right." Alex said, a lump in her throat forming as she saw how Kara desperately tried to pat out the fires raging on her body, brushing off the remnants of her clothing. Alex took out her PDA and extended the antenna to scan Kara.

"Why didn't it work, Alex?" Kara asked plaintively, looking at her sister as she blinked back tears.

"It, uh—seems to have set off a chain reaction. I'm reading an increase in Red K radiation."

"More? What does that mean?"

"Assuming my math is right," Alex said, stumbling over her words as if the longer she held them back, the longer she could keep them from being true. "then the effect won't last for 24 hours. It could last up to two weeks."

Kara let herself cry a little bit—just a little bit—in the bathroom before she flew home as fast as she could. She'd have to quit her job. There was no other way. She sent a resignation letter, effective immediately, to Cat Grant. And whatever her faults, Cat was extremely lenient about the two weeks' notice stuff. She tended to run through personnel too fast to stick to the letter of the law in that case.

Winn called her shortly afterward, insistently on an explanation in that almost demanding way of his. It all spilled out of her—how could it not, he was her best friend?—she told him how the clothes had practically peeled off her body, how she'd inadvertently destroyed the beautiful suit he had made her, all the shame and embarrassment she had felt being paraded around DEO headquarters stark naked. In a choked voice he said he understood and to tell him if there was anything he could do to help, while suppressing the primal pleasure he felt at Kara's current predicament. She couldn't bear to tell James, though. Shamelessly, she texted Alex to cook up an explanation for her. She knew Alex blamed herself for all this and so would do whatever it took to make nudist life easier for Kara. Kara mollified herself by thinking that giving Alex something to do to help would make her feel better about the whole situation.

Then—with her curtains very soundly drawn—Kara set about waiting out the kryptonite poisoning. At least it didn't seem to be triggered by her wrapping herself up in a spare blanket, for whatever reason—maybe because it was so thin that it just glazed over her body, making her appear more naked than naked when she caught a glimpse of herself in a mirror. It was the lingerie of blankets, seemingly to cling extra tightly to Kara's perky breasts or pert buttocks, at least to her eye. It made her wish she had a Snuggie.

For two interminable days, she watched TV, surfed the web, got into way too many social media discussions of the new Star Wars movies, worked out a complicated system of paying for delivery food without answering the door that compelled her to tip twice as well, and hoped really really hard that no aliens would attack the city.

Was this what it was like when Earth women got periods? How awful.

Cat called her, half to demand an explanation for her absence (and passive-aggressively tell her to get her ass back to work) and half to vent about her new assistant, a college graduate who was adamant that Cat talk to him in his native Spanish when he was at his desk, since it was his safe space and he found being spoken to in English a colonialist 'mislanguaging'.

Even getting whisper-threatened over the phone like she'd butt-dialed Batman was better than lying in bed all day, so Kara listened attentively and agreed with all Cat's points and went over Alex's hermit cover story—Alex had practically written a dissertation for her on it—and it finally got to the point that Cat promised Kara her job back so long as she promised never to work for someone named Jack Ryder.

Kara couldn't really backtrack the turns in the conversation to where they'd reached that point, but she agreed. Upon which Cat acidly 'apologized' for the building's custodial staff disposing of all her personal belongings when she'd quit. Kara nodded to herself. Working for Cat, she'd long ago left all sentimental items at home, where they were out of range of frustration-induced crushing.

Then, four days in, it happened. She got a call from J'onn.

"One of our Fort Rozz escapees gave up the goods. We still don't know the General's plan, but he fingered a Carggite refugee who would know more. Apparently Astra did some business with him, and he's somewhere in Bludhaven. If you could find him—"

Alex's voice took over the line. "We can find him, Kara, we just want to talk to him, there's no need for superpowers—"

"We can't know that." J'onn retorted. "If the Carggite talks to us peacefully, that's one thing, but he's a triplicate hive-mind, able to shift energy between all three of his forms. That's power we'd be hard-pressed to deal with."

"So we'll just find him once Kara has—recovered."

"And give the enemy additional time to enact her plan? Whatever she has planned, it could already be an active threat!"

"Guys!" Kara interrupted, feeling a migraine headache beginning. "I'll do it. J'onn's right, we don't have time to sit around and… anyway, it's nighttime, I'll just fly high, move fast, no one'll see me."

Alex's voice went as strident as their mother's. "It's an unnecessary compromising of one of our top agents—"

"You're telling me she can't do her job if someone sees her naked? Never seemed to stop Jennifer Lawrence."

"It will impact her morale!"

"And whatever Astra's planning won't?"

"Alex, I said it was fine." Kara interrupted again. "Superman wouldn't let himself be too embarrassed to do the right thing, and neither will I."

She could hear Alex sigh heavily, right over the line. "You know Mom'll kill me if so much as your bare back turns up on TMZ?"

"I'll be faster than a speeding camera phone. Promise."

Kara flew high above Bludhaven, telescoping her vision down to the city streets. The Carggite wouldn't be easy to spot—three identical men moving in lockstep, maybe. She almost hoped she wouldn't find them, have to confront them, but she did her best regardless. The DEO couldn't afford to let General Astra get the drop on them.

After a few hours of prowling the skyways, Kara was almost comfortable with her nudity. The darkness hid her body well, while the waning moon gave her nice enough light to see by. Really, it was silly that they had even debated this—Alex being overprotective. So what if people saw her naked, so what if it ended up on the internet even? Why should she be ashamed of embarrassment in pursuit of a worthy cause? Would Superman care about getting photographed from a bad angle while he dug out a collapsed mine? No! Why should she?

She spotted them just before morning, midway through a dark alley. The triplicates had a street walker boxed in like that Night At The Roxbury sketch, teasing her, feinting at her scant clothes. She wasn't unreceptive, but she was holding back, making some kind of argument that frustrated them. Supergirl flew down, taking refuge behind a big cypress bush growing alongside the mouth of the alley—some kind of ill-fated beautification effort. It, and the darkness, would shield her from prying eyes. She sent a line of heat vision cutting between the sex worker and the Carggite(s), getting their attention.

"You want to tell me why you're hassling the lady?" Kara demanded, in an overcompensatingly bold voice.

"Supergirl!" one of them (him?) cried.

"Is it? I can't see…"

"Who else has heat vision?" the third demanded, taking the words right out of Kara's mouth.

"Superman?"

"Did that sound like Superman?"

The lady was as impatient with this as Supergirl. She broke from the pack to get a little closer to Supergirl. "These bums want me to party with them, but they're only willing to pay for a party of one. Not three!"

"Why should we pay for three?" the Carggite demanded, all in unison. "We're all one person!"

"Yeah, and they're in some kind of cult too." the woman added.

"You'd better leave." Kara told her. "I'll handle this."

"Yeah, plenty of normal weirdos who want to party." she sniffed as she walked off on five-inch heels. "A two-for-one special I've heard of, but three—"

Supergirl faced the Carggite as she left, staring them down, trying to impose her will too heavily for them to question or doubt her.

"Say." one said, "what's with the bush? Don't you Supers usually like to advertise?"

"Yeah! You don't see Superman just poking his head out from behind a tree—"

"Do you want more heatvision?" Kara demanded. "Because I've got more heatvision!"

They demurred. She pressed on.

"General Astra of the Fort Roz aliens contacted you. I want to know why. If you cooperate, I'd be willing to keep you off the DEO's radar."

"DEO?" they sneered. "You think we're afraid of the DEO?"

They dissipated into one individual—the same bald, brawny man there had just been three of. "You have to catch all three of us to get me. Otherwise—"

And then there were three of them again. "You're out of luck!"

Kara gritted her teeth. Imagined them moving in three different directions, stealing cars, boarding subways or buses—every time she caught up to one, he'd disappear into the other two. It'd be like trying to catch running water. "Alright. But I still need to know everything you know about General Astra."

"What's it worth to you?" they insisted. "Enough money to pay that nice lady for all three of us?"

Supergirl hadn't carried money around even when she'd had pockets. Good way to lose rent money, getting into an alien fight with fragile, flammable bills on your person. "I don't have any money—"

"No, seriously, what's with the bush?"

"Is it a Batman thing?"

"She always stands out in the open on the news…"

Kara sighed. She was angry with herself, being stuck in her apartment for almost a week, letting her powers lie fallow and feeling useless just because she was embarrassed to show a little skin. Who cared if she was naked? Hell, who cared if she had sex? No one seemed to care who Superman was flying with. In that moment, she suddenly, absolutely wanted to make up for her own cowardice—to own her sexuality instead of being embarrassed or ashamed of it. She took a deep breath before she emerged from behind the bush, showing her body in its naked beauty. "Happy now?"

They were actually averting their eyes before they gave in to gawking, seeing how unconcerned she was at her own nakedness. Kara liked the feeling of being gaped at a little. It wasn't like she had anything to be ashamed of. She loved her body! It was great! She put her hands on her hips and did a little pose, turning her head a little to show off her heroic chin, giving them a smile and winking a tidge. The Carggite triplets eyed her with a leery look before Kara's eyes narrowed and she knocked them out with a single punch. Well, this was fun. In a weird way. Kara just hoped no one was recording her, since the last thing she needed was become the hot topic in CatCo tabloids.

As it turned out, she did, much to Kara's embarrassment but at least her nudity was pixelated in the news, magazines and the Internet and James and Winn tried to suppress their urge to pleasure themselves, while J'onn and Alex were uncomfortablr and were unsure whether to pity Kara or be ashamed of her or to be amused, until Alex got a sterny lecture from Eliza about how could she let Kara end up naked for two weeks. Even though most of the time Kara disposed of the aliens and criminals so quickly her nudity was just a blur, it had become obvious what happened but Kara didn't care. At first she felt ashamed of her nakedness but soon enough she gathered more confidence and courage regarding her sexuality, not worrying about exposing herself anymore, at least until the radiation from red kryptonite wore out and dissipated from her skin and she could wear clothes again, even though she was not going to give anyone the opportunity to have sex with her and she was uncomfortable with becoming a sex object the men could please themselves to but Winn and DEO managed to erase most traces of Kara's public nudity from the Internet. Most traces.

And soon enough, Kara was able to regain her job but the topic of naked Supergirl saving the day was a topic she wanted to avoid at all cost and Kara hoped she would not have to face more red kryptonite in the future. While nudity was not horrifying and embarrassing and humiliating to her anymore, she still felt uncomfortable about the unintentional sexualization of her alter-ego and reputation but at least there were no rumors of her whoring herself or something like that.

Well, poor Kara but at least she gained some more confidence.

I probably gave an impression of a perv but in real life I have my limits and remember this is fanfiction, where people come to unleash their fantasy, so refrain yourself from harsh critique and name-calling since people have written worse.
