Smut-Crisis of Two Earths: Kryptonite Enhancements

Kara didn’t know why she was here. She and Lena weren’t exactly talking after she discovered Kara had been lying to her for their entire friendship, discovering she was Supergirl. Their friendship was on thin ice since. Lena Luthor didn’t take betrayal well, resulting in her plotting being Kara’s back to try and brainwash the planet into peace and using her trust to steal from the fortress. Needless to say, things had gotten rocky. But Kara didn’t want things to stay that way, she valued their friendship too much.

That’s why she came, despite her reluctance. She hoped they could clear the air and start mending that bridge, maybe apologize for the hundredth time.

She took a brief moment to pause outside her office window, taking a deep breath figuring out what she was going to say. She could see Lena in her chair with her back to her, probably working as usual. So, before she could change her mind, she flew down to the nearby balcony and entered the building. “Before you say anything, just let me apologize” she said , walking quickly into her office. “I know I broke your trust. I shouldn’t have lied to you, you feel betrayed and hurt, but I’m trying to make things right. So if you could…”

She stopped when she saw Lena was only half dressed, her jacket and blouse open exposing her chest, her bra askew, her pants discarded a few yards away along with her shoes. She still wore her panties, but they had been pulled aside to make way for the young cock presently slipping out of her pussy. She hadn’t been sitting in her chair directly. Instead a young dark haired demigod Kara knew as Percy Jackson was sitting in it, completely naked, with Lena sitting on his lap. Kara realized she’d interrupted the two of them having sex, quickly turning her back averting her eyes. “Oh, sorry, I didn’t realize you were…” she said flustered. “I should come back later.”

“Well, you’re here now” Lena sighed, climbing off her boy toy and crossing her arms. “You might as well say what you came to say” she suggested.

Kara wasn’t so comfortable of having this conversation while Lena was half naked and dripping cum onto the floor, especially not while Percy stood awkwardly behind them in the nude. But if Lena was willing to listen, she guessed she didn’t have a choice if she wanted to be heard. “I just… I don’t like how we left things between us. So is there any way we can try and work through this? I’d like us to be friends again.”

“Do you?” She said, walking over with her hands behind her back. She fixed her eyes on Kara’s as she stalked forward, an intense glare burning into her soul. She was still festering the betrayal and hatred, but she was calm as she came face to face with Supergirl. “You really think this can be fixed?”

“I’m willing to try” Kara insisted, on the verge of begging. “Just…tell me how I can fix this.”

Lena thought about it, tapping her foot looking up at the lamps surrounding the office. After a short while, Kara’s gaze finally followed, noticing the lights Lena must’ve installed since the last time Kara was here. They hummed quietly as they cast their invisible light into the room. Kara’s chest clenched when she realized they were red sun lamps. She tried not to panic, the memory of what Lena did to her in the fortress still fresh in her mind, looking back to find Lena glaring back at her.

The next thing she knew, Lena had moved quickly, grabbing Kara’s wrists and latching a pair of power dampening handcuffs on them.

“I’ll tell you how we fix this” Lena hissed, dragging Kara over to her desk and shoving her into the chair, watching the helpless and powerless kryptonian struggle as she stared up at her. While Kara had been averting her gaze, Lena had activated the red solar lamps in the office and retrieved the power dampeners from a nearby drawer, holding her finger to her lips as she glanced at Percy. Waiting for the right moment, she subdued Supergirl. Now she was at her mercy, Lena had big plans for her. “Do you have any idea what it feels like to be hurt and betrayed by someone you call a friend?” She asked her, leaning forward on the chair staring at her. Kara gulped as Lena answered “when you leave this office, you will have an idea of how much you hurt me.”

Kara wasn’t sure if she liked where this might be going. But she wasn’t expecting it to start with her former best friend roughly kissing her on the lips. Lena was forceful as she sucked the air out of her lungs, taking her breath away as she put her hands on her shoulders, pinning her to the chair. She was too stunned to kick out or anything, forced to allow the kiss until she got back her senses. But by the time Kara recovered Lena had pulled away, leaving her breathless and in shock as she stared at the raven haired woman, who walked back to her desk where Percy stood obediently.

Reaching into her desk, Lena retrieved a heavy lead box keeping it out of sight of Supergirl. “I’m glad you came to visit Kara” she said, quietly seething with anger as she directed Percy over to join her. “I can finally put my latest experiment to use” she said, opening the box and taking the glowing green item from inside. Kara could see what she was holding, but immediately she felt a burning sensation across her skin making her tense in fear. “Don’t worry” she calmed her demigod friend when he looked worried, watching her slide the kryptonite ring onto his erection. “I has no harmful effects on humans. I made sure of that. But I can’t say the same about other alien species” she added, stepping aside so Kara could see the glowing green cock ring Percy was now wearing.

Kara shuddered in fear when she saw the kryptonite toy, squirming in her seat when Percy took a step forward bringing it closer, her body feeling like hot irons were being ignited under her skin. Lena came over and took hold of her arm, dragging her onto her knees on the floor. Due to the handcuffs and red sun lamps, Supergirl was unable to break free as Lena dropped behind her, positioning the blonde in front of Percy holding her still as he approached slowly. She watched her skin turn pale as green vines grew over her flesh, relishing the pain she was inflicting, clutching her arm tightly grabbing her by the hair keeping her face turned towards the throbbing erection. She promised Percy the kryptonite would harm him, but didn’t explain a handy side effect was the radiation enlarged his penis to double the size, along with causing his balls to swell. It would wear off once he took the ring off, but until then they would be spoilt young women.

“Please, don’t do this” Kara whimpered, squirming with Lena trying to turn her face way, get away from the kryptonite making her skin crawl. Her eyes darted to Lena, who’s expression was cold and stern. “Please” she begged.

“It’s just a cock” Lena whispered. “It can’t hurt you” she lied, yanking on her hair to force her to cry out, opening her mouth so she could shove her onto Percy’s cock.

Kara lips burnt the moment her mouth was pushed onto the penis, reacting to the cock ring at close proximity. She tried to scream but the enlarged dick choked her, stuffing her throat thanks to Lena pressing her palm against the back of her head. She forced her to deep throat the boy, chocking on his member, all while she fought against the pain, her eyes watering. She couldn’t believe Lena was making her do this, powerless to stop her, begging for it to end.

Percy wasn’t up for this at first, but once Lena put the ring on his erection he was driven mad with lust. And once Kara’s mouth was around his penis he was consumed with animalistic intent, growling in pleasure when he grabbed her head and began slamming himself deeper into her throat ignoring her pleas. Lena grinned in approval as he brutally skull fucked the superhero, utilizing his godly strength bruising her lips as they turned green. He wasn’t sure how long prolonged exposure took to kill a kryptonian, but they both assumed Kara would survive long enough for them to be done with her. Kara considered the same, realizing it would be agony until they let her go. Her pain got worse when Percy came, ejaculating into her throat. His cum burned, his swollen balls now contaminated by kryptonite. Lena had yet to test the long term effects of irradiated sperm, but so far experiments showed the effects weren’t permanent. It didn’t stop him producing kryptonite sperm to burn the inside of her mouth making Supergirl scream.

Lena yanked her off the boy when he was done, throwing her onto her back watching the girl cough and whimper. She gasped for air, feeling a little better now she was away from the penis, his cum scalding her throat as she reluctantly swallowed. Tears streamed from her eyes as she stared up at the ceiling, feeling weak and drained. Lena appeared in her peripheral, removing the last of her clothing, pecking Percy on the cheek before climbing on top of the blonde. Before she could do anything, she was straddling her face grabbing her by the scalp, pulling her mouth onto her pussy. “Yes, that’s right. Suck it” Lena growled, grinding her pussy onto Kara’s face, almost suffocating her.

Kara struggled under the woman’s weight, kicking out wildly straining against the cuffs. But somehow her mind managed to tell her tongue to start licking the pussy covering her, sensing it was what Lena expected. Lena enjoyed dominating her opponents, just like all Luthors. If Kara wanted this over, she had to let Lena win. So she orally pleasured her, sucking her folds between licks, putting the practice she’d had with Nina to work.

Lena was a difficult woman to please, but Kara got rewarded in other ways. Percy knelt down and reached under her red skirt, grabbing her panties and yanking them down her legs over her knee-high boots. Kara felt his hands on her and panicked, kicking out at him only for him to grab them prying her thighs open. He lowered his head down to her pussy, holding her legs still as he penetrated her with his rough tongue. She moaned in response, her voice muffled within Lena’s cunt, regretfully submitting to the pleasure while delivering her own to Lena. She didn’t want to admit how good Percy was making her feel, despite the restraints and forceful nature of the sex.

Lena was impressed. She was expecting Kara to crumble after the kryptonite blowjob, but she seemed to adapt rather effectively. Very naïve and inexperienced, but quite good at licking her pussy. She was taken by surprise when she was brought to a gentle orgasm, drowning her former best friends face with her cum. Kara climaxed soon after, squirting all over Percy’s face. She was released a minute later, gasping for air licking Lena’s cum of her lips.

“Well, that was very impressive” Lena said, kneeling over Kara looking down at her. Kara looked up, nervous and worried of what she might do next. “Did I sense a little bit of enjoyment from you?” She asked suspiciously. “I’m afraid we can’t have that” she muttered, standing up and nodding to Percy.

He walked over and pulled Kara off the floor, dragging her over to the desk while Lena walked over to a nearby cabinet. She opened a drawer and retrieved an item, listening to Kara’s whimpers as she was bent over the desk with her butt hoisted up, her cape bunched over her back as she lifted her skirt. Now that Percy was standing right behind her she was within range of the effects of the kryptonite again, her skin burning in response. “What are going to do to me?” Kara asked fearfully, her cheek pressed to the glass surface.

“I thought that would be obvious” Lena replied, attaching her experimental invention to her crotch strapping it around her waist. She turned around once it was in place, showing Supergirl the slim smooth dildo hooked to her groin. The fake cock was designed to deliver sensual pleasure to both the recipient and the wearer, sensors positioned along the shaft and against her clit to make it feel like she was operating a real cock. She spent a lot of evenings with her male test subjects to get the design right, and even more with testing it on herself to make sure it was working correctly. Now she’d get to give the prototype its first field test. “Be a dear and warm her up for me” she ordered her partner, activating the toy by stroking it, feeling the sensors pulse against her groin.

“wait, what are you..? No!” Kara screamed as Percy obediently penetrated Kara from behind, shoving his thick kryptonite cock into her tight pussy igniting a burst of pain to shoot through her body. Supergirl screamed in agony as radiation burned through her core, spreading through her system intensifying every sense in her skin. Her nipples became sensitive, along with her clit and pussy, underneath the burning fire raking underneath her flesh. When Percy thrust into her, it felt like she’d been impaled with a massive iron hot rod, her eyes watering from the pain and reluctant pleasure. “Please, it hurts. Stop!” She whimpered, powerful to resist as Percy fucked her mercilessly.

Lena watched in fascinated amusement as Kara was taken from behind. He understood it was the kryptonite that was causing all the pain, without it she’d be a happy slut for the young demigod. She considered removing the cock ring so the hero could get a little pleasure, but then reminded herself why she was doing this; to teach Kara a lesson about betrayal. But more curiously was how much this synthetic cock felt like the real thing as Lena massaged the rubber coated metallic shaft, the sensors feeding signals to her groin making her Boyd believe it was real. She moaned softly when she squeezed experimentally, feeling a crushing pressure against her clit. The hand job felt good, but Lena could do better.

Walking around the desk, Kara looked up with tears in her eyes begging for help. But Lena revealed her strap on to her, watching her expression turn to fear as she took hold of her face, thrusting her cock into the girl’s throat. “That’s it. Suck on that for me” Lena gasped with a smirk, the dildo sending signals through her pussy so she felt Kara’s mouth around the shaft, feeling her choking on it as she stuffed the thick cock into her mouth. She looked down at the blonde, who was staring desperately up at her, thrusting into her mouth roughly while Percy fucked her from the opposite side. Kara was spit roasted across the desk, whimpering painfully as her veins turned green.

She somehow orgasmed in the middle of this assault, the climax ripping through her increasing her agony. Lena got really excited from her dominant position too, silently cumming into her dildo. The fluid was collected into a pair of small inflatable sacks underneath, growing a pair of balloons resembling balls. It was an interesting feature she added at the last minute, a novelty she thought would be funny, able to expel the contents when they reach capacity, or when she chose. Across from her, Percy was also on the verge of climaxing, grunting in warning groaning “fuck she’s so tight. I’m about to cum inside this tight cunt.”

Kara panicked when she heard that, terrified of having sperm radiated in kryptonite spilling into her womb. Lena thought about it too, realising such exposure to her system would be too lethal for a kryptonian. She didn’t want Supergirl dead. “No” she ordered, pulling out of Kara’s throat ignoring her sputtering gasps, marching over to Percy to put an authoritative hand on his chest. He was pushed away, his penis dragged out of her cunt begrudgingly, leaving Kara groaning but relieved as the effects of the kryptonite lessened. Percy looked disappointed at Lena, who held his gaze warning him “You’ll get your chance.” She then turned back to Kara, looking down at her bruised and red arse still quivering from the effects, her skin still a faint green colour. She returned to the hero, running her hand over her backside, feeling her tense in fear. “Not until I get to break her.”

Kara could formulate a question or a response, her mind already fuzzy and broken by the time Lena hand decided to smack her bottom really hard. Pain jolted her awake making her cry out, her weakened flesh leaving a bright red mark on her bum. Lena spanked her a few more times for her own enjoyment before aligning her cock at her entrance. Kara braced to receive the dildo into her pussy, thankful it at least wasn’t made out of kryptonite. But then Lena adjusted the position instead aiming at her anus, and Kara’s chest tightened. Lena waited for Kara to beg, to plead with her not to do this, but the girl had learnt it wouldn’t make a difference and stayed quiet. She was disappointed, but proceeded to penetrate her back passage forcefully.

The technology continued to astound both of them. The synthetic cock felt so real, delivered all the right signals to excite both the receiver and the owner. Lena didn’t quite get the same sensations a man would, but she got a close approximation running through her core. She groaned as she thrust against the superhero, gripping her hips tightly slapping her arse repeatedly. Kara moaned and cried in response, submitting to the scientists brutal assault giving up on escape. She focused on what little pleasure their fucking was giving her, recovering from the kryptonite poisoning slowly spying Percy jerking himself a few meters away. Her eye line was broken when Lena decided to yank her up by her blonde hair, arching her spine against her so she could reach under the helm of her top and lift the costume up over her chest. The moment her boobs were uncovered Kara turned red regretting forgetting to put a bra on that day. Lena smiled, playing with them firmly, giving the demigod something to masturbate to as she pinched and twisted her sensitive nipples. She wished she’d been this forward during their friendship, maybe they could’ve enjoying this moment in less hostile circumstances. The number of evening she sat in her office toying with the idea of motor boating these firm tits, imagining Kara in her dorky glasses calling her name as she sucked them and squeezed them.

But those fantasies were gone now, replaced with furious rage as she dragged a devastating climax from herself to fill the swelling sacks beneath her toy. Kara slumped trembling in her arms, her feet dragging limply underneath her struggling to remain steady. In her weakened state, prolonged sex was exhausting her, making it difficult to stay awake. Lena spun her around and slapped her hard, waiting for her focus to return to her stern gaze. “Don’t you pass out on me” Lena warned. “We’re not done yet.”

“I’m sorry” Kara whispered.

She paused in confusion, in the process of groping her roughly preparing to re-enter her when Supergirl responded. “Excuse me?”

“I’m sorry” Kara repeated, looking up at her apologetically through her tears. “I’m sorry I lied to you. I should’ve told you who I was instead of letting you find out from Lex. I should’ve been honest. I don’t have any excuses, you were my friend. But I’m trying, trying to make it up to you. So if this is something you need to do, to hurt me, then I won’t stop you. I won’t resist. But I can’t undo the mistakes I’ve made. All I can do is promise not to lie to you again. And I hope one day you’re able to forgive me and we can try to work through it.” She took a deep shaky breath as she sat up on the desk, looking at Lena as determined as she was able. “So just do what you need to. I’ll still be here for you.”

Lena was dumbfounded as she stared back at the young woman, shocked at her little speech feeling her stomach churn a little. Kara always had a way of breaking down Lena’s barriers. But she would let her melt her heart today. “No” she muttered, grabbing her by the shoulders and impaling her with her cock. “You don’t get to apologize, it won’t work” she insisted as Kara winced silently, biting her lip bracing against the intrusion offering no resistance. Lena thrust into her cunt, raping her pussy, while Supergirl let her be assaulted. She let her use her to vent all her anger and pain. “You can’t undo what you’ve done to me!” Lena cried, clawing at her breasts and neck leaving deep red cuts over her flesh, digging her nails in until Kara had no choice but to scream in pain. “If you want to understand my pain, then you will” she hissed, grabbing her by the thighs and lifting her off the desk to carry her over to her pet.

Percy was waiting obediently a few feet away when Lena signalled for him to join them once more. He got transfixed in watching the two hot women have sex (or rather watching Lena rape Kara) masturbating furiously bursting to cum. Something about the cock ring was preventing it, forcing him to build up a lot of pressure. When Lena carried Supergirl towards him he leapt to her side, sprinting behind the hero to align himself at her spread cheeks. Kara became more sensitive the moment she got close to his kryptonite infused cock, her veins turning bright green as pain clawed at her body. Lena pressed her against Percy’s broad chest, sandwiching the girl between them, pushing her loosened anus onto Percy’s engorged penis. Kara’s eyes watered as it stuffed her back passages, stretching her walls sending lightning bolts of kryptonite agony up her spine.

“I spared you his seed earlier because there’s a chance his sperm might kill you” Lena whispered as she pushed Kara’s hips further down Percy’s erection, burrowing her own cock deep against her cervix were she could feel it rubbing against his between her walls. “Now I want this to hurt, and to hear you scream, and maybe then you’ll understand the pain I felt when I found out my best friend lied to me from the very start.” She grabbed Kara’s jaw and kissed her roughly, biting her bottom lip drawing blood. “Then you’ll understand how much I hate you, Supergirl.”

As promised, Kara offered no resistance no matter how much pain and agony she was in. She let Lena and Percy fuck her in both her holes, let them hold her legs and waist, allowed them to grope and choke her as she bounced on their cocks trapped between their powerful bodies, her own body weak and powerless from the power dampening cuffs and red solar lamps and kryptonite cock ring. She let them have their way with her, praying to Rao this would help Lena heal and let them move forward. She also hoped she was wrong about the kryptonite sperm killing her, because she could sense the demigod’s need to cum and guessed it wouldn’t be long until he busted his nut inside her ass. And despite all the pain and torment, there was still a tiny part of Kara was was enjoying the rough sex with her best friend and her stud.

Percy was enjoying it too, her tight anus squeezing his swollen cock begging him to explode. He kept groaning and grunting, clutching her thighs letting Lena attack her breasts, the woman’s synthetic balls growing with each spillage of fluids. The girls kept coming while he continued to wait for his climax, his balls aching more and more. “Fuck…just…fucking….why…won’t…can’t…I…urgh!” He bellowed, finally ejaculating into Kara’s ass.

She screamed as the demigod painted her insides, radiated cum pouring into her anus filling her insides. It felt like acid pumping into her intestines, igniting a new wave of pain to shock her system. Soon after, she climaxed herself, painfully shuddering in their arms. Then she was shocked when Lena managed to force her cock past her cervix to breach her womb, where she surprised Kara with a special feature of her sex toy. With a firm tap of a hidden button, all the cum and fluid collected in her sack was pumped through her dildo to squirt into Kara’s uterus, filling her with liquid as if it was a real penis. This wasn’t irradiated, but it still felt hot to her insides. Lena smiled, happy to see the feature worked as intended.

When the collective orgasm had finally subsided, reserves drained and empty, Kara was deposited unceremoniously onto the floor in a heap, cum leaking out of her bruised holes, her skin pale with green veins covering her flesh. Her breathing was ragged and laboured, her blonde hair sticking to her face. She felt exhausted, weak and bloated as two pools of cum sloshed inside her belly. He no longer had the strength to move, everything felt numb when it wasn’t aching.

Lena and Percy stood over her limp body, looking down at her with satisfaction. Lena looked at her watch and sighed. “Well, that was cathartic” she said, removing the strap on and returning it to the cabinet. Then she retrieved her clothes and got redressed, efficiently cleaning herself up and composing herself. She was very adept at presenting herself in a short space of time. When she was done tying her hair back, she came over to tell Percy “I’ll leave you to lock up. Shirt he for the lamps are under my desk, along with the key to the handcuffs. I’m sure Supergirl can find her way out the way she came in, unless you want to continue without me. Now, I have a meeting to attend” she said. She didn’t bother to say goodbye when she left the office, disappearing out the door hoping they’d both be gone by the time she came back.

Percy was equally exhausted, his muscles sagging after all the animalistic sex. He looked down at Kara and finally realized what he’d helped do. He felt sick, muttering an apology as he pulled the glowing cock ring off his dick and returned it to the lead box. Kara’s breathing got slightly easier now it was safely gone, but the infect still lingered under her skin. He hurriedly raced to the desk, finding the switch to the red sun lamps and deactivating them before returning to uncut her. “I’m really sorry” he whispered to her, receiving a sluggish nod before she blacked out. In a fugue state, Percy got dressed and decided to return home to half-blood hill, find Annabeth and his friends. To seek forgiveness. Feeling guilty, he left the office and the building.

A few minutes later, Kara woke back up still aching and poisoned. But now that the lamps were off and the dampeners gone her powers returned bit by bit. Enough to get her up onto her feet and drag herself onto the chair. She waited until she got her breath back, waiting for the room to stop spinning, before she retrieved her discarded underwear and pulled them back on, fixing her costume. She felt horrible, and not just physically. She knew Lena was hurting, but she never thought she’d do something like this. Dragging herself forward, she stumbled over to the window and stepped onto the balcony, slumping against the banister resisting the urge to throw up. She still had kryptonite burning through her system, making her lightheaded as she pulled herself into the air. It was a miracle she was able to fly back to her apartment, collapsing onto the bed finally passing out. It would be sixteen hours later when Alex came looking for her. Kara wouldn’t tell her exactly what happened, not even after she’s taken to the DEO to be treated for kryptonite poisoning, but did explain that things between her and Lena weren’t going to get better soon.
