Chapter 1 - Seething Sister Kristi

“Kristi, can we fuck? Please!” Jack wailed in the morning as he rubbed his erection.

He had been rubbing it the whole time. Kristi had lain by his side, pretending to be asleep as he tried to get off, no doubt to the thought of her previously mousy older sister who had shown up and turned her life upside down.

She didn’t even care that Jack was masturbating furiously the whole time. What she really wished was that he would fucking finish so he would leave her alone.

Kristi continued to pretend, but Jack reached over and started shaking her arm.

“Kristi, Kristi, it’s 8:00 AM... wake up...” he panted.

“FUCK’S SAKE, JACK!” She ceased pretending and hurled the blankets off.

Climbing out of bed, she started to put on some morning clothes.

“Kristi! Wait! What about...” he begged as he continued to tug at his shaft.

“Fuck you, Jack! Go call her about it!”

“I... I did! Please, can you reach out to Kayla for me? I... I’m so obsessed with her! I’ll do anything to make it up to you! Whatever you want. Just, just... help!”

Kristi ignored him and went to her computer. She was going to threaten to evict him.

Her screen unlocked, and on it was a picture of her older sister Kayla, in all of her naked glory. Flowing, dark fiery red hair spilling down her back, sun-kissed skin and striking silver and gold heterochromic eyes, her impressively toned arms bent at the elbow and blowing a kiss at the screen...

A black pushup bra that accentuated her superhumanly large and firm breasts at their absolute finest, pressing them together to form a cleavage that neither Jack nor Kristi could tear their eyes away from...

All that, and her spare hand curled upward with visible electric lines flowing from her fingertips to spell the word “cum” in midair...

Jack erupted as he sobbed in pleasure. He tightened his fingers over his spurting tip as he continued to pump erratically while his body bent.

“Ohhhhhhh Kristi... Kayla... thank you!” he grunted in between large ropes of cum.

Even Kristi had trouble tearing her eyes away from the still image that had somehow gotten onto her screen. A second later, her desktop wallpaper flashed to a new image of Kayla laughing condescendingly at her. Or Jack? Both?

How was she doing this!? There was no way this was Kayla!

But it looked like her shitty apartment room. With her stupid fucking penguin plushies. And she’d left that little physical penguin souvenir by Kristi’s bedside table too.

“Oh fuck, oh fuck,” Jack moaned. He had just finished firing his long denied load, but the squish of flesh rubbing flesh began to increase in intensity again.

“JACK! GET THE FUCK OUT! NEVER COME BACK HERE!”

---

After threatening not to reach out to Kayla on Jack’s behalf ever again, she shoved him out the door and threw his clothes right at his face as he continued to stroke his stupid fucking dick in the hallway of her apartment complex.

Locking the door on him, she went back to her bedroom and shed a few tears. It was still too difficult to process. Her unambitious, admittedly smart, and totally unrecognizable sister had become some sort of unstoppable lust goddess. And not just brain-frying beautiful. She could turn into electricity too!?

Kristi went to the bathroom to reflect and check her reflection. She’d always sized herself up against Kayla. Big sister was always so smart. Got such good grades. Kayla had blossomed first and drawn the attention of all the boys though. Her big sister had always been such a chip on her shoulder. Maybe it wouldn’t have been so bad if big sister had actually been the tiniest bit assertive. Instead, her passivity and willingness to be bowled over by anyone else’s demands just drove Kristi insane. She swore she’d never grow up like that.

She’d used her well developed body to get what she wanted out of the boys who lusted after her. And in a vain attempt to “teach” Kayla, she’d begun tormenting her. Gently. At least that’s what she told herself. Snatching Jack away from her was supposed to be the spark that lit the flames inside Kayla in their college years... but no. And now Kristi was stuck with this stupid man-boy she didn’t even like, all to teach her big sister a lesson.

Kristi hadn’t accounted for Kayla to become some sort of... superhuman.

This was all her fault!

And now, what the hell did she have? She’d busted her ass in college for her economics major, all in a bid to keep up with Kayla. It had borne fruit. Kristi was making six digits her first job out of college in a finance position. But... that had other complications attached to it.

She examined herself in the bathroom mirror as she mentally compared herself to her big sister. It was not good for her self-confidence. Kayla was now taller—leggier, to be more specific. That only made it worse. Somehow wickedly fit. Tiny waist.

Kristi cupped her breasts and pushed them upward. Nope. Not even close. The new and improved Kayla had her beat by double. Maybe more than double.

Fuck.

The younger Kinetic sister had never felt ugly before. Even with her tired, bleary eyes, she was quite striking with her own seductive form and unbreakable swagger. But the swagger was broken now, and comparing herself to a superhuman goddess of beauty and power made her feel even more diminished.

What would she have to do to catch up to Kayla now? Was it even possible?

Her phone buzzed. A text message from her boss on a Saturday morning. This could mean only one thing.

Chapter 2 - ArcTech’s Predecessor

“You give me a booty call on Saturday morning and you didn’t even buy me coffee?” Kristi asked as she walked into her boss Craig’s office.

“You work for me, remember? Part of the job,” he smiled.

Kristi tossed her purse on Craig’s office chair and leapt into his arms. He picked her up in her strong arms as she wrapped her legs around his waist and held on tight while they shared a deep, passionate kiss.

“So what’d you tell the wifey this time?” Kristi grinned when she broke the kiss and began to undulate her hips against Craig’s body. She loved the smell of his musk and deodorant after his morning workouts. The chemical concoction invaded her senses with its tingling chill. Kristi breathed deeply to get another whiff.

“Oh honey, I’m sooo busy with work. Fuckin’ clients, you know,” he laughed as his hands roamed her backside. He pressed her torso flat against his to enjoy her warmth and the feel of her soft swells flattening against his.

His arms getting sore, Craig swiveled around and urgently shoved the papers and writing implements off his desk and deposited Kristi in their place. He pulled his t-shirt over his head in one fluid stroke, revealing his chiseled body. Kristi was busy unbuttoning her blouse, revealing a plain cream bra underneath.

They were going at it again before the familiar beep of a badge being scanned interrupted their little cheating tryst. Kristi swung her legs over his desk and crawled underneath the little “sexmatary space” as they called it, while Craig agitatedly put his shirt back on and buttoned his trousers.

“Yoooo Craig,” some damn colleague of his waved at him through the window of the office.

“Hey Todd,” he replied curtly as he tried to stand as wide as possible.

Kristi’s arm shot back up and around the desk to yank her forgotten blouse into the sexmatary space with her.

“Working the weekend?” Todd asked stupidly.

“Uh. Yeah. Real busy here. Good talking to you Todd,” he tried to end the conversation quickly.

“Ayup. Uh huh. See ya.”

Craig shuffled idly, pretending to be busy as he watched Todd shamble out of view.

“Fucking hell! Is he gone?” Kristi whispered.

Craig drummed his fingers on his desk.

“Aaaaaand... gone.”

Kristi climbed out of the confined space with a huge smile. They both knew that the threat of being caught was part of the thrill. But right now, they both just wanted a good rutting.

“Come on. Let’s go,” Craig pushed Kristi off of him when she tried to climb back up.

“What? Why?”

“I owe you breakfast, apparently. I’m just too nice of a boss. And I know somewhere exciting we can go.”

“Oh yeah? What is it?”

---

“So, Dr. Lee, my creator, or should I say, Dr. Frankenstein... tell me...” Kayla whispered into Vivienne’s ear as the nude, irresistible goddess of electricity traced lingering lines over Vivienne’s body.

“Unnnng!” Vivienne seized up.

The sparking sensation emanating from Kayla’s sensual fingers across her erect nipples launched Vivienne into an orgasm immediately. It didn’t matter that she’d been enduring Kayla’s erotic torture for the last fifteen minutes, her wonderful dominant mistress wracking her body with pure bliss and deepening Vivienne’s loyalty to the redheaded bombshell who could cause men and women to wither and submit to her just by being seen. It didn’t matter that Vivienne’s body was about to give out, wrung dry from sexual exhaustion.

As soon as Kayla’s soft fingers traced across her nipples, Vivenne was helpless to resist. God forbid Kayla actually touch her down there...

Although Vivienne wished she would.

“Were you going to try this on yourself?” Kayla asked as she nibbled the eccentric Asian’s earlobe. She swirled her powerful tongue as she nipped at it with her teeth while she continued to let her hand drift lazily over Vivienne’s vulnerable body.

“Huh! Mmf! Yes...” she admitted as her pussy clenched. Sparks of pleasure burst behind her half-lidded eyes. Her mouth was agape, gasping for mercy as her body continued to convulse in sheer ecstasy. Vivienne thought she was about to break in half!

“And you really didn’t know it would work?” Kayla ground her body against Vivienne’s side. Her soft, supple, warm skin rubbed static tingles against Vivienne’s arm, her enormous protruding breasts swallowing it whole. They were so much larger than Vivienne’s, so firm, so full, so proud and perfect. Kayla slithered her long leg over Vivienne’s, sending more sparks of submissive pleasure coursing right into Vivienne’s dominated soul.

“Wanted to run... small scale testing, more iterations” Vivienne began grinding her hips against Kayla’s limb of her own accord. “Would probably have tested it on myself after hours. Like a true mad scientist,” the fog of lust began to dissipate from her brain as she answered Kayla’s questions. She was nothing if not fully devoted to her life’s research.

“Hmm...” Kayla let Vivienne writhe in her embrace as she thought to herself. “More iterations? You’ve tried this before? Does your old research still exist after ArcTech burned down?”

“Nothing current. We have an old abandoned lab..."

“You would never try to surpass me, would you? You love me, don’t you? You love feeling this way.”

“Yess...” Vivienne moaned.

“Maybe you can make yourself a little better. Be my empowered pet. Last year’s model. I’ve kind of taken a liking to you,” Kayla whispered conspiratorially. “Maybe you can be my front desk receptionist!” Kayla laughed at the little getback. She stopped touching Vivienne to allow her some oxygen.

“Oh, mistress Kayla! Yes! It would be an honor!”

---

After two cups of Largissimo Javaccinos at their local coffee drive-thru, Craig drove toward the abandoned ArcLight building while Kristi slurped on his cock, lying across the center divide of the front of the car. This new graduate was definitely worth her six figure salary, and probably would be for a few more years until he found and hired a new one.

He parked the car in the abandoned lot as Kristi bobbed up and down on his erection peeking through the unbuttoned top of his shorts. She worked his shaft even harder when he parked the car, pumping harder and faster with her hand as he killed the engine.

“Fuck, not here. Come on, let’s go,” Craig instructed, placing a hand on her back.

Kristi made a noise of protest before she popped off his dick with a wet slurp and wiped her mouth with a towel from the backseat.

The pair strolled into the disused building. Craig badged right in, to Kristi’s surprise. It was surprising the sensor mechanism even worked, considering how vacant ArcLight looked from the outside.

“What the hell is this place?” Kristi asked as they walked in.

The tepid smell of stale dust filled the air. The interior looked like an office from a different era, far in the future. A large, wide open space with oddly shaped chairs and an asymmetrical table. Presumably all of it had been a pristine pearl white before being stained by dirt. A rusty-looking logo that read “A---ight” was displayed proudly behind a receptionist’s desk. Kristi was immediately reminded of her sister and growled.

“Some eccentric entrepreneur that we took a chance on. Young. Asian. She made the news a while back.”

“You guys funded this?” she asked in disbelief.

“Yeah... got swept up into the biotech revolution. It was really hot. Maybe a bubble. Oh well,” he shrugged.

“Did you fuck her?” Kristi asked without judgment.

Craig just smiled at her without responding.

“So why did you wanna show me this?”

“Ever wanted to do it ‘in the future?’ I’ve been dying to visit here again.”

“Interesting fantasy of yours,” Kristi remarked before putting two and two together. “So you did fuck her.”

“Maybe. Why do you care?”

“Is she hot? Was she a good lay?”

“You’re getting weirdly insecure for two people who are both cheating,” he commented.

“This place doesn’t look clean,” Kristi changed the subject.

“Come on. This area is just whatever. There’s this crazy lab in the back. Looks totally untouched. You won’t believe it.”

As they walked down the hallway to ArcLight’s prototype lab, the lights in the hallway began to come on with a deep, rumbling hum as a streak of white electricity seemed to light their way.

“Whoa,” Kristi commented. “You’re right. This is like something out of a movie.”

“Weird... I think I would’ve remembered that,” Craig said.

“Creepy?” Kristi was beginning to feel a little nervous as their footsteps echoed through the corridor.

“Eh. What could go wrong? Look at this place. Nobody’s been here.”

Kristi followed with unease. Craig swiped his badge at another thick glass door with black borders, and it slid open with a loud whoosh. The chill of cold, sterilized air greeted them as the lab lights also turned on.

The place was absolutely pristine! A constant hum flowed through the lab as its vacuum tubes and consoles lit up. It really did look like something out of the future.

“Whoa... what is this, some amusement park ride!?” Kristi marveled.

“Like i told you. Asian eccentric genius biotech researcher. Or so we thought. Four and a half million in this place before she rebranded and moved into another building. She said this one she’d built was too unstable or something. Wanted more money for something less powerful. We weren’t interested, so.”

“They got any music in here?” Kristi examined one of the futuristic computer display screens.

“Beep boop beep boop,” Craig joked as he began to strip. He pushed  a few buttons at random. “I guess not.”

Kristi followed suit. Or unsuit.

As she lay on one of the clean tables, legs up and wrapped around Craig’s torso with him standing and thrusting in and out of her, the lab began to whir to life. Flashes of light traveled through the vacuum tubes, sounding in sync with Craig’s thrusting.

“What the fuck... is going on,” Kristi asked, more confused than aroused. “Did you do something?”

“Don’t know... fuck... it’s so hot,” Craig muttered. “Stop talking... will ya?” He gripped her calves near his chest and continued to thrust.

“Yes, little sister, you always did have so much to say, didn’t you?” a familiar voice rang out.

“Whoa! Kristi, was that your voice!?” Craig moaned as he pumped. His eyes were closed.

“N-no...” Kristi whispered.

A bolt of lightning shot out of the overhead fluorescent lights and coalesced into a pool of energy on the floor. The bright, opaque light began to grow taller and taller as more electricity took on mass, its silhouette forming the shape of a tall, long limbed, huge chested, beautiful woman.

“Holy fuck! What was Vivienne doing here?!” Craig pulled out and began to panic.

Kristi’s face was more despair than horror. She already knew what was about to happen.

The silhouette of glowing energy began to transform into an actual human woman. The ghostly illumination began to fade as a long, flowing red dress with high leg slits came into existence. It hugged the electric goddess’s curves, accentuating her wide, flowing hips and tight tummy before concealing a ridiculously well-endowed bust. The dressed-in-red woman’s breasts seemed to stretch that conjured fabric to its limit. It must have been twice her width, carving out so much space in front of her body, so large and yet so, so firm to be standing high and proud like that!

Her pair of matching red high heels only exaggerated and enhanced her beautifully long limbs. Her skin took on a healthy sheen, encasing her beautifully muscled physique while still retaining her femininity. Her bare arms too, so long and so powerful, ending in her slender fingers curled around her cartoonishly small waist.

The tendrils of electricity swaying off her head in thick strands turned into a fiery mane of long, billowing dark red hair. The features of her heart-shaped face also finalized as well, displaying a pair of beautifully backlit pale precious metal eyes, a cute nose, and plump, kissable lips.

“Nice to see you again, sis. Who’s this?”

Kristi could only meep.

Craig’s erection twitched powerfully as he laid eyes on this towering beauty. He’d been fucking Kristi no less than a minute ago, but just looking at Kayla was about to make him come! His dick twitched as he drank in as much of her sexy, muscled, superhuman body as he could. There was no way, right? He couldn’t come just from looking at a woman, could he?

“You’ve been cheating on Jack this whole time?” Kayla interrogated her sister.

“N-no...”

“No?” Kayla arched a perfect eyebrow. “You. What’s your name? What do you have to say?”

“I’m Craig,” he muttered almost inaudibly, too stunned and too aroused to speak. “C-Craig!” he tried once more.

“Has my sister been cheating on her boyfriend with you? I had a crush on him before she took him away, you know.” Kayla examined her fingernails.

“She... took him away? From you?” He was completely flabbergasted.

“Yes, yes. That was so long ago, though. So tell me, is she cheating on her boyfriend?”

Craig didn’t know what to say. He looked at Kristi for help, but her face exuded only pure shame as she avoided all eye contact with either party. Not shame for cheating, but the shame of inferiority.

“Don’t look at her for help, you spineless idiot. But tell you what... if you need motivation, I’ll make you come if you tell me the truth. How does that sound?” Kayla laughed. She was so confident in her new powers now! Incapacitating the entire population at the Penguin Pub in a little celebration orgy certainly hadn’t hurt her ego.

“Yes, yes! She’s been cheating! I don’t know his name, but she has! Actually, I’m cheating on my wife too! I’ve been really unfaithful my whole life!” he blurted out as an extra confession. He would tell this redheaded electric goddess anything to satisfy her.

“Oh Kristi... what’s the matter? Jack wasn’t enough for you?”

“No! Not after what you did to him! He’s... he’s always asking for you now! You... you’re the cheater! You cucked him while I was in the room!” Kristi redirected the accusations.

“Please... can I... fuck you?” Craig was practically begging! He trembled and quivered in anticipation.

Goddamn, Kristi wanted THAT! Men begging after little more than a glance, not one shred of dignity left in the inferno of their desire. How had her sister done it? How could life be so unfair!

“Soon, baby, soon. How long have you two been fucking?” Kayla asked, her voice a silken purr.

“As soon as I hired her. It was a big part of the reason why we even took her,” Craig admitted. “She was more than happy with the arrangement.”

“Tsk tsk tsk, Kristi. So much for your moral high ground,” Kayla tutted.

Kristi wanted to scream. All her life’s work, all of her little ploys to get ahead... it was all falling apart!

“Please! Can I fuck you now? I’ve told you the truth! All of it!” Craig was almost in tears. He wanted to tackle and insert his leaking, needy erection into Kristi’s inexplicable superhuman older sister, but he was still of sound enough mind to realize how dangerous and powerful she was.

“Mm... you do know how to choose them though, Kristi. First Jack. And now this hunk. Sure thing, honey. And if I know anything, you’ll never be able to orgasm again unless you’re fantasizing about me. Does that sound okay with you?” Kayla offered him a choice with a sly smile. As if he had a choice.

“Yes! Yes! Anything! I’d pay any price to be with you!”

“I’m going to collect on that, sweetie,” Kayla cooed. “Now get ready...”

Before Craig could process her movement, Kayla had blurred and was atop him. A quick fling of the flap of her dress revealed her perfectly smooth, bare pussy. She climbed atop him, supporting her own weight effortlessly by gripping the powerful trunk that Craig called his torso.

He didn’t know what to do. How was this girl so fast, so strong, so powerful? And the electric touch of her smooth skin sent his frayed nerves into overdrive—was he going to finish without actually getting a chance to be inside of her?

Kayla sensed his turmoil and gave him a little wink before burying himself over him, bottoming out in one fluid motion.

Craig gasped in pure, ecstatic shock as her slick, velvet warmth gripped him tightly inside of her.

Kayla just stayed motionless, speared on his steely pole. She watched his inevitable reaction to being enveloped by her perfect intimacy with a look of pure bemusement on her face.

Craig’s jellied legs trembled as he clutched at the sleek fabric of Kayla’s red dress, arms quivering and body quaking as he erupted deep inside of her. The unbelievable erotic sensation of Kayla’s superhuman folds wrapping him up, so warm and quaking, somehow goading his virile cock to erupt even without any movement on her part was too much to withstand! Powerful, shocking tingles of desire pricked his member, sending coursing pleasure into his already boiling loins and overwhelming his mind with thoughts of nothing but Kayla.

He was coming. Desperately. Urgently. Even as his legs folded and he collapsed to the floor into a clumsy heap, Kayla rode him all the way down weightlessly, never letting go of her intimate grip over his searing rod. Pulse after pulse of his dwindling juice erupted from his hypersensitive cockhead as Kayla took it all, cooing and goading him all the way.

“I think he likes it!” Kayla taunted as his fluid splashed inside of her cervix, spraying like a firehose.

“Too... much...” Craig uttered in between violent clenches. He was audible wheezing, trying to suck air into his ragged lungs as his roiling testicles continued to contract and erupt, squeezing out every last drop for Kayla’s unrelenting sexuality.

“Oh little sister, have you ever made him come like this?” Kayla taunted. “You stole my crush, so it only seems fair that I steal your sugar daddy, don’t you think?”

“OH GOD!!” Craig bellowed as his aching loins were taxed beyond their limit. But he had no choice but to continue to orgasm unproductively as Kayla’s breasts swallowed his head and rubbed his face with their enveloping softness while her pussy continued to shock and began to stroke his long exhausted cockhead.

“Kayla! Stop! Please...” Kristi begged with tears in her eyes.

“Funny thing: I wasn’t even coming here for you,” Kayla declared as she gracefully climbed off Craig’s floorbound body. He’d been through enough erotic torture. As soon as he slipped out of Kayla, he closed his eyes and fell into a deep slumber.

“What? Then why are you here?” Kristi sobbed. “Why are you doing this to me?”

“Come now, Kristi. What happened to that brash little sister of mine? You tortured me for most of our childhood. One little cheating boyfriend seems mild in comparison. And, I’m here to destroy this complex. I see you’re as motivated and scheming as ever, Kristi. I understand what you’re doing here. You’re here to try to catch up to me, aren’t you? To become like I have. Good thing Vivienne belongs to me now.”

“Wha...?” Kristi didn’t understand.

“You can play dumb all you like. I’ll be nice to you again, once I get my little vengeful streak out. But for now...”

Kayla turned to look at a comatose Craig, erection still at full attention despite the pleasure wringer she’d just put him through. No doubt he was dreaming of her even in his sleep, mouthing her name and begging to be with her, now and forever.

The thrill of dominating yet another man, especially one that was with Kristi, was turning Kayla on. Kayla was always on now. But she didn’t want Kristi to know how much she actually enjoyed “fucking” Craig. She wanted to show her little sister how in charge she was, how she could just use people and discard them without a second thought, as Kristi had done to her all their childhood. But now that Craig was out cold, Kayla could take care of her own burning arousal.

She raised her arms into the air, those long, muscled limbs with their taut, smooth skin reaching toward the ceiling in glorious display. The room’s lights began to fluctuate, dimming and illuminating.

“What are you... are you going to kill me?!” Kristi bellowed over the roar of Kayla’s power.

“Oh please, Kristi. I’m not some kind of evil villain,” Kayla moaned as she began to drain the facility’s power.

The bolts of lightning thickened as Kayla really flexed her muscles. Her eyes turned white and opaque as she bathed in its electric radiance, head to toe. The tendrils of electricity swirled especially actively over the protruding peaks of her breasts and the slick, inviting junction between her well-built thighs.

The energy surged through Kayla’s own electricity-formed-goddess’s body, stimulating her already aching wetness and sensitive nipples to a mind-blowing orgasm. Her red mane stood up on end as beams of power burst from her eyes and her fingertips. Kayla floated into the air, back arched as her mouth opened wide, screaming in pleasure.

“Yesssss!” she wailed, before thick beams of power burst forth from her mouth, her quivering nipples, and from deep in her womb, firing outward like artillery.

The entire laboratory shuddered under her electrical bombardment as she came, wrecking what was left of ArcLight laboratories. The displays overloaded with electricity, their screens shattering as the prototype vacuum tubes shattered, releasing Vivienne’s special substance into the air.

Soon, the sparks ignited the lab and engulfed it in strange, glowing blue flames. In the midst of all of it, Kayla’s body clenched and relaxed, each orgasmic release firing more endless power along with it.

As she finally came down from her energy draining orgasm, Kayla’s hair obeyed the laws of gravity once more as it draped over her nude body, still full and voluminous. She conjured her pair of red heels once more and placed them on the shuddering earth with a pair of loud clacks. The entire lab was engulfed in an ethereal blue flame.

“Oops... I guess I overdid it,” she commented almost with regret as she idly touched herself in front of her little sister. “But I can’t let you gain this sort of power now, can I? Come on, I’ll open a path out for you and your boss.”

Kayla strutted over to the lab’s only entrance, kicking heavy tables aside with a halfhearted brush of her legs and sending fallen beams flying with a flippant sweep of her arms. Jabbing her fingers into the doorframe, the material cracked and warped under the force of her steely fingers. With a light tug of her arm, she pulled the entire barrier off its gliding track.

“Take your little friend and get out of here. I’ll see you later, little sis.”

Kayla turned into electricity once more, bolted into the ceiling, and was gone once more.

Chapter 3 - Kristi Kinetic Pyrotechnics

Kristi screamed and cried in despair in the midst of the burning ArcLight laboratory. All of her justifications about why she bullied Kayla, all for the sake of teaching her big sister a lesson and making more of her life, it all came crashing down on her. She never wanted Kayla to surpass her! She loved tormenting her wallflower of a big sister. And now that Kayla had actually become more sexy and seductive than anyone could ever imagine, Kristi was feeling what she could only assume was karma. And it was a bitch.

She knelt there, resting on her haunches, looking at Craig’s erection as he continued to slumber. Then, she looked out toward the exit that Kayla had carved with her unaided limbs. What was the point? Now her boss was going to be Kayla’s sex slave, just like Jack. Would she even have her cushy job now? Maybe. Craig would probably be begging Kristi to see Kayla again.

Fuck.

As she remained there unmoving, the electrical fires mixed and swirled with Vivienne’s prototype material, now being released into the air and becoming activated by Kayla’s wanton destruction and fire. Kristi’s deep, sobbing gasps sucked up the burning ash and particulates in the air. ArcLight’s mystery biotechnology went deep into her lungs, got picked up by her red blood cells, and began to travel through to the rest of her vital organs.

After entire minutes of idle brooding, self-pity, and helplessness, Kristi got to her feet and went to fetch an unconscious Craig who was still sporting a stupid goofy smile on his face. However, as she bent over to slap him on his stupid face, her entire body seized up.

The heat of the blazing building was nothing compared to the sudden burn that seemed to be coming from inside her body. More and more deep breaths accelerated the process as more of ArcLight technology made its way inside her, bonding to her cells, initiating her fateful transformation.

The ghostly ethereal fire ignited inside of Kristi with one final breath.

Raging, blue flames engulfed Kristi’s body as her eyes went wide with shock. She whimpered in fear, but those beautiful wavering lights didn’t inflict any pain at all. Quite the opposite, in fact.

Her brunette hair had their color stripped away by the lashing flames, her pigmentation fading away to an ashen white even as it lengthened and flowed down her back in a glorious, thick, lustrous mane. Almost as a parting touch, the ArcLight fire blended with her milky locks, tinting them bluer before they finally settled on an otherworldly shade of beautiful, light purple.

Her hair wavered in the air as if it were the fire itself. Transferring from her tresses to her body now, Vivienne’s trade secret ignited behind Kristi’s brown eyes, searing away her only-human biology and turning her irises and transforming them into a beautiful pale blue that flashed white when the light caught it from a specific angle.

A small wisp of violet fire expelled from Kristi’s mouth as she felt the fire massage her scalp and even her brain, enhancing her neural pathways with powers unimaginable. The little tinder grew in intensity as the enhancing fire began to make its way down her waiting body.

It crawled down her skin, purifying it of all blemishes, leaving it smooth, silken, and satin. The embers cleansed all imperfections as it trickled down her neck and over her smooth shoulders, burning away her clothing and enhancing and magnifying her allure, leaving behind a beautifully carved collarbone and widening her shoulders in preparation for what it would do to the rest of her enhanced frame.

The blue blaze licked and lashed down to her breasts, cupping and massaging them in cold fire as the peaks of the flame traced and caressed Kristi’s nipples. They teased those aching buds, engorging them and sending limitless erotic pleasure through her nerves as her fiery bra fondled and cradled her feminine flesh, expanding outward in lockstep with her growing breasts.

A sudden surge of pure passion ignited deep inside of her as if granting her deepest desire. Her mountainous swells continued to push outward, filling out with dense, firm, erotic flesh. Larger and larger they grew on her chest until it spilled beyond the sides of her torso, stretching but never tearing. In the center of her chest was the most incredible cleavage anyone had ever lay eyes on. Kristi had seen Kayla’s... and she knew this to be a fact.

She inhaled another deep breath of Vivienne’s prototype biotech, and her breasts made one final push, perking up, defying the force of gravity as they swelled almost beyond the measure of good taste.

Kristi eyed herself with wide eyed amazement as the flames finally left her chest and continued to swirl down her body. She wanted to touch her breasts so badly, those begging-to-be-fondled nipples vibrating with pleasure as they gushed with her own inner fire. But she didn’t want to risk disturbing the most amazing thing that was happening to her right now.

Still in disbelief in shock, Kristi could no longer see past the prodigious swells on her chest that purported to be hers, but she could feel the tickling heat working its way down her abs, leaving a deeply carved groove of a beautiful six pack over her midsection. A quick blue fiery exhale blasted out of her nostrils as her waist cinched inward, driving the air from her lungs, not that she’d ever find herself short of breath. Not anymore. Even despite controlling the flow and power of fire.

A tingle resonated deep in her hips before her bones creaked as they widened, matching the beautiful width of her shoulders. Her trimmed pubic hair caught actual fire as they singed and burned to ash, falling away from her new, perfect body. A separate fire of arousal burned deep in her womb and her back took on a beautiful arch while her already curvaceous ass tightened and became even more dramatic, more alluring than ever.

Even without sight, she could feel her legs growing longer. Her arms and fingers began to adjust in tandem too, all lengthening to match her new height. The little hairs that she’d spent hours obsessing and shaving were no longer a concern any longer, incinerated to nothingness just like her delicate pubic mound. All that was left was tight, delectable, female flesh. Thighs strong and muscled, calves carved and dainty, feet elegantly arched and toes perfectly painted. She had to be at least as tall as Kayla now, and she felt twice as sexy.

The pleasure never ceased burning inside of her body. Now that every inch of her body had been perfected by ArcLight tech, the constant thrum of power that had morphed her DNA, granted her superhuman abilities, and perfected her DNA all surged directly to her intimate core, each powerful vector feeding the flames of Kristi’s passion. Every last trace of power gathered deep in her needy womb, making her vagina burn in beautiful ecstasy, each ember intensifying and stimulating Kristi’s new enhanced nerves. Every simple movement, every twitch of her new muscles was a mild orgasm that added to her stockpile of growing pleasure.

As every last punch of power traced a path of pleasure through her body, her quivering pussy lips and blazing, sopping clit ached ever stronger. She began to drip her sweet honey which instantly incinerated from the heat radiating off her body. Her perfect nether folds, and the burning tips of her breasts which jutted so far out from her body, all of it glowed brighter and brighter as the power burned hotter than she could bear!

When the final tendrils of latent energy slammed into Kristi’s erogenous zones, she exploded in ecstasy.

Her eyes ignited with scorching passion as ArcLight’s biotech set her free of her constraints. Those silvery blue mirrors burst into flame as she curled up into a little ball, gasping and heaving as she tried to survive and ride the wave of her impending orgasm.

Kristi’s hypersensitive nipples brushed against her sculpted thighs, causing her to roar in pleasure as erotic sensations surged through delicious nubs. Jets of flame erupted from her breasts and caused her skin to glow white hot before another orgasmic detonation erupted from her eyes, mouth, and breasts as her body quaked and shuddered in sexual satisfaction.

Her hair constantly shifted between light purple and searing white as she continued to quake and moan. The heat in her womb was still building and still unbearable! Despite orgasming twice already just from brushing her sensitive nipples against her own smooth skin, Kristi still felt as if there was a stopper bottling up all of her power and prevented her from achieving her true climactic peak.

She unclenched her shivering body just a hair's width and shoved her arm down her torso, brushing her breast and causing it to spurt another volley of flame in the process. All of the flames in the lab were dancing and twisting in echoes of her shuddering movements. She flung her arms wide, thrusting her breasts out towards the burning lab equipment, breathing in deeply. Her breasts rose, not just with her filling lungs, but sucking in the flames, their heat, growing a second time. Her breast inflated like balloons filled not with air, but the power of heat! They felt tight, huge, swollen, perfectly rounded orbs a match for even her enhanced sister’s curves. Kristi moaned, feeling the energy gathered in them slowly trickle into the rest of her body, giving every part of her another blast of over the top grandeur. She was a goddess of heat and lust!

Her sensual fingers traced down her cobbled abs and began to work greedily at her begging clit, the ghostly pale flames rising off her long fingers  adding a fiery touch to her own urgent teasing and rubbing.

Swirling two burning fingers over her not so little nub of pleasure, constantly draining the heat from the fires around her, she quickly worked herself to a frenzy and uncorked the stopper that was holding back her pleasure.

Kristi erupted again.

Her nether lips clenched and relaxed rapidly, seeking something to grip as her inner core exploded in pleasure. Her shitty little human nerves were burning away, reforming as goddess nerves to handle the sexual overload that was taking place in her superior body. Her skin was flushed, her extremities tingled, and her muscles grew rigid as her legs extended to their full glorious length as she squirted herself silly while continuing to work her fingers over her folds and her throbbing clit.

Kristi growled again, firing another jet of flame from her mouth to scorch straight through the ceiling. All of the concrete, wood, and steel evaporated or turned to ash, burning a hole straight through the ceiling to the morning sky. Another press of her fingers, another clench of her pussy lips, and her eyes sent two beams of molten heat straight into the sky as well, evaporating the clouds above.

The white hot glow of her body finally began to recede. Her nipples were too sensitive to touch lest she trigger another blazing orgasm. Her pussy was sweet and dry, no trace of fluid left from her volcanic eruption. Kristi couldn’t believe this was real.

She felt strong! Powerful. Sexy.

Divine.

When she regained her senses, she floated to the ground and touched down with her bare feet. Craig had been shunted into the far wall from her ministrations, singed but alive. As he came to, he caught sight of the violet haired fiery angel.

“K-K-Kayla?” he muttered. He knew it wasn’t the electric goddess who had shattered and rewired his mind, but who else could be this sexy, this otherworldly in her beauty and power?

“Fuck no,” Kristi replied flatly. She strutted toward the prone Craig who had inadvertently pissed her off. Real bad.

As her inhumanly shapely body sashayed toward him, Kristi’s radiant beauty began to take control of Craig’s male reactions. The sight of a huge chested, elegantly long limbed, sashaying goddess advancing toward him caused his penis to stiffen and show the new Kristi the respect that beauty like hers demanded.

“Whoa, ung, I...” Craig struggled. The more he stared at Kristi’s beauty, those haunting, inhuman silvery-blue eyes, the less control he had. He tried to maintain a modicum of self-control, but he simply couldn’t. His arm trembled as he reached for his quivering erection.

“Pathetic. Let me,” Kristi scoffed.

She squatted next to his prone form, reaching for his steely rod with her smoldering hand. When she gripped him, he began to spurt immediately. His fluid arced into the air in thick loads from Kristi’s hot grip and long, soft fingers that encircled him fully.

“Unnng! Oh, fuck! Kayla, Kayla, I’m coming!!” Craig bellowed.

“Piece of shit!” Kristi spat.

Her eyes blazed as she tapped into her newfound power. Two fiery lasers and ten seconds later, there was nothing left of Craig but ash.

Gods didn’t feel remorse. Just cold, burning fury.

It was time for payback.

Chapter 4 - The Kinetic Sisters United

Kayla floated in the air, suspended by electric tendrils from the ceiling as she wrapped her legs around Eddie’s face. Splayed out around the Penguin Pub were six other individuals, both male and female who had been incapacitated and exhausted by Kayla’s loveliness. Well, that and her body’s rampant appetite for sex.

“Oh Eddie, tell me how devoted you are to me!” Kayla moaned as she undulated her hips, grinding her sweet pussy against his mouth. “It turns me on so much!”

“Oh Kayla,” he muffled into her vagina as he reached with his hands to squeeze her incredibly firm butt. “I can’t get enough of you! I always think of you when I fuck her!”

“Fuck! That’s so hot I’m gonna come!” Kayla squealed.

But before Kayla could achieve another orgasm from her favorite lover, an enormous blast of flame burnt down the door to the pub and its surrounding walls.

“Big sister! I have a score to settle!” Kristi announced, entire body alight in fury.

Kayla looked toward where the sound had originated, completely startled out of her favorite worshiping session ever since she’d achieved goddesshood. Was that really Kristi?! No! How had she become enhanced just as she had!?

Eddie just orgasmed in his pants as Kayla’s sexuality and sweet juices overwhelmed him for the third time that session.

“DIE!” Kristi screeched.

She raised her arm and emitted a powerful billow of flame. Kayla got in front of Eddie and shielded him from certain death by bearing the brunt of Kristi’s attack with a quickly conjured electric forcefield.

“Kristi! You can’t be serious!” Kayla yelled as her perfect body actually began to sweat from the extreme heat. Eddie took the opportunity to back away from the devastation taking place before him.

“S-sorry Kayla!” he apologized as he ran for his life.

“Go Eddie, go! I’ll talk her out of this!”

Kristi spread her fire engine red lips in a roar of flame, turning her head to follow Edie’s retreat and forcing Kayla to drift sideways to keep the protections of her shield between him and her sister’s fiery rage.

“Kristi! You’re going to kill someone!” Kayla shouted, still baffled that her sister was now every bit as shapely and powerful as herself.

“They deserve it! They all look at you and don’t even see me anymore. Why did it have to be you?! This power could have been mine alone.”

Kristy’s fiery breath swept across the bar, making the bottles explode in puffs of blue alcoholic flame. The shards of glass and flashes of heat stung Kayla, but Kristi’s body arched in sexual bliss as the wave of returning heat struck her hungry breasts.

“Kristi! You have to calm down! Maybe I was too eager to fuck you over, but you’d been torturing me for years! Let’s just talk…?”

“NEVER! You took my boyfriend! And my other boyfriend!” Kristi redoubled her flames, scorching the ceiling beams as the wall continued to burn around them.

That was quite enough for Kayla, her own patience evaporating in the heat of the burning bar.

“Only after you took him from me! And you’ve got to be crazy to be killing people!” She began to swell up slightly, taking on an ominous purple glow as she drained the building’s electrical system.

“I want what’s yours! All those years I wished I were as smart as you and I watched you waste it. I hated it! And then... and then you actually got hotter than me and took away the only thing I had going for me!” Kristi’s lush form was swelling too as she bathed in the inferno she’d created. SHe unleashed another roar of fire, pounding her sister’s barrier directly.

Lightning and flame crackled and ripped open the air in front of Kayla, tiny holes burning through her protection, creating searing jets of flame that reddened her otherwise perfect skin.

“How are you... so... strong... unng...” Kayla was beginning to weaken under Kristi’s excessive power. Why on earth was her little sister more powerful than her?!

But ArcLight’s power had a cost. A kink that even Vivenne had deemed too unstable, too risky to try. Kristi’s body, just as matchless as Kayla’s but even more powerful, began to overheat. She yelped in pain as her supple skin began to blacken and char while her power spiraled out of her own control.

“Kristi?!” Kayla shouted over the roar of burning flame.

“Kayla! Help! I can’t stop! I’m... I’m dying!”

Kristi redirected her painful self-immolating attack, incinerating the last of the unwitting orgy members that were still trying to recover from Kayla’s loveliness. Her flames turned the walls of the tavern to ash as tears evaporated from her eyes before they could even make its way down Kristi’s anguished face.

Kayla panicked. She didn’t know what to do. Her little sister whom she’d never gotten along with was at the gates of death, pleading for help for the very first, desperate time in her life.

Without a second thought, she zipped over to her little sister and embraced her rigid, trembling, flaring limbs in a tight hug. Kristi whimpered in fear and comfort as the fires began to come under control. Her muscles relaxed as the flames died down, and slowly, moving her arms one anguished inch at a time, she weakly returned her big sister’s affection.

The ArcTech and ArcLight biotech began to mix. Kristi’s body was still deteriorating, and the more unstable chemical began to suck up Kayla’s power greedily. The older sister didn’t fight it as she continued to hug Kristi tight. Their bodies glowed in a pale, refreshing blue hue as Kayla turned into her pure energy state and melded into Kristi’s wrecked body, repairing their dual body and magnifying their combined superhuman power and sexual allure.

When Kristi/Kayla opened her eyes, she stood even taller than before. More compelling. To look at her was to know the impossibly perfect female form, never achieved before by humanity. Her long limbs, her seductive smile, her fierce, glowing eyes, and those breasts, those incomparable breasts that could conquer men’s and women’s souls on sight, or with a simple glancing touch... the Kinetic sisters had become more than human. They were a walking sexual dynamo, fire and electricity combined, their sum greater than its parts.

The newly birthed goddess opened her eyes: one silver, one blue. A whole group of firefighters had responded to the catastrophe. As soon as they witnessed Kristi/Kayla’s glorious, undeniable beauty, they all collapsed to their feet as they lost control of their bodies to her fertility goddess figure and beautiful, bountiful breasts. Twitching and jerking, firing load after load into their pants, they kept their eyes open as much as possible to drink in the sight of pale acres of luscious, feminine flesh, impossible perfection given form.

“I feel... oh yesss!” their combined voice rang out, Kristi’s more than Kayla’s. It was so smoky, so laced with erotic desire that the entire troupe of firefighters’ eyes rolled up into their heads as they continued to orgasm beyond their limit, their testicles churning drily as their members continued to pump.

The Kinetic goddess smiled at the effect she was having on those hapless men. Lunging forward with incredible physicality, she placed a chaste kiss on every man’s lips.

Their hearts failed as they attempted to process the pleasure. Every last one of them hunched over dead, with an enormous, satisfied smile on their faces as their bodies’ electricity and residual warmth swirled up to join with the Goddess.

“Oh, this is going to be fun,” Kristi’s voice declared, shivering with pleasure as she drank in the death throws of the last firefighter. “I want to see what you found so special about that bartender. Him, I’ll make come for hours before he finally falls over dead.”

“Hey!” Kayla’s voice took over. “That one’s mine! Leave him for me!”

The two sisters as one resumed their internal struggle. Their tumultuous relationship never lost a step.

Epilogue

Vivienne explored the ruins of ArcLight, scorched and smoldering. It had met the same fate as ArcTech but in a drastically different way.

Kayla hadn’t visited her in a week. Vivienne had typed into her computer, waiting for her mistress’s playful reply to appear on the computer screen before she zapped out of the computer in a tasteful yet revealing dress. And then give Vivienne another jolt of sexual pleasure enough for a whole lifetime.

So where was her mistress? The knot in Vivienne’s stomach began to tighten.

Kayla had suggested that Vivienne use her own biotech on herself. She had her mistress’s permission. Maybe if she powered up, then mistress Kayla would find her worthy. Maybe it was a test.

She began to gather the usable remains of ArcLight and load them into a truck she’d rented. ArcTech gear was there as well. A fusion of her two technologies should lead to her most advanced concoction yet...
