It had been four months since Tony had revealed his knowledge of the future to Pepper. Their relationship had deepened in ways neither of them had expected. Late-night conversations had shifted from shared dinners and simple company updates to discussions about their plans for the future—an impossible future they now had a chance to reshape. Tony had spent sleepless nights reflecting on how they had paid an unbearable price despite their victory over Thanos. The deaths of friends like Natasha, the fall of Asgard, the catastrophic Civil War among the Avengers, and disasters like the Ultron incident—they weren't all tied directly to Thanos, but they were events that had scarred the timeline and Tony was determined to avoid them this time.
He had realized early on that brute force wasn't the solution. The problems they faced were systemic, stretching far beyond any single villain. And so, Tony had shifted his focus toward expanding Stark Industries internationally, far more aggressively than he had in the original timeline. He needed resources and influence—global reach that would allow him to pull the strings from behind the scenes. In the last four months, Stark Industries has grown tremendously the company which previously was valued at 80 billion dollars was not valued at 200 billion dollars they had dominated the markets in various fields with the new Mobiles, laptops, and tablets they had left Apple and google(According to 2008, I know in 2024 they are in trillion dollar companies but not in 2008) in the dust with the new Operating system from 2024 they didn't stand a chance along with the arc reactor, prosthetics, and aviation he would soon be the richest man in the world. He would not be caught unprepared again. The Civil War had fractured the Avengers last time, and Tony swore he would never allow that kind of division to happen again. His hands had been tied before, bound by government oversight and politics. This time, he wouldn't be manipulated by Thaddeus Ross or any bureaucrat eager to control their power.
Behind the scenes, he'd set JARVIS to monitor Ross's activities. Already, evidence of corruption and unethical actions was being collected quietly. Tony wanted to be ready when the time came to neutralize Ross before he could force their hands into another doomed Sokovia Accords situation. He'd seen what unchecked power in the wrong hands could do. Last time, he had let it get too far. This time, he intended to expose Ross's dirty deeds before any conflict could arise, ensuring no one could pressure them into divisions again.
His thoughts often returned to Bruce Banner. The Hulk had already made his first appearance, but Tony had been working to keep Ross off Banner's trail, using JARVIS to subtly manipulate data and reports. From what Tony remembered, the Abomination incident was on the horizon. This time, he was determined to use it to Banner's advantage. Instead of the Hulk being painted as a mindless monster, Tony planned to reshape the narrative. He would make sure that the world saw Hulk as a hero, someone to be trusted, rather than feared. That had been his mistake in the original timeline—letting public opinion turn against them too easily.
Then, there was HYDRA. Hacking into their mainframe had been child's play for JARVIS, especially with the updates Tony had designed using his knowledge of future technology. It hadn't taken long before Tony had unearthed files relating to Wanda and Pietro Maximoff. The twins were still out there, unaware of the fate that awaited them if they volunteered for HYDRA's twisted experiments. Contrary to popular belief, Tony did care about them—deeply. They were just kids, manipulated into a war they never chose. As soon as they showed any signs of being drawn into HYDRA's web, Tony had already resolved to intervene. This time, he wouldn't be responsible for their suffering. He had JARVIS on constant surveillance, ready to alert him when Wanda and Pietro made their fateful decision. When that time came, Tony wouldn't hesitate to rescue them before it was too late.
"Sir Thaddeus Ross has started making his move, he is getting desperate and is conducting various illegal human experiments for the super soldier serum among them Emil Blonsky has gotten the best results so far he has gained enhanced abilities but that has made him aggressive, and unstable he is now researching the Bruce Banner's gamma-irradiated blood sir and according to my estimate he will have his results in a week sir"
"Good work JARVIS continue keeping an eye on them and inform me immediately if anything abnormal occurs."
"Understood sir."
"Moving on, how are the updates to the Mark 50 progressing?"
"Sir, the advancements in nano-technology for the Mark 50 are progressing very well. The integration of nanobots has been successful, enhancing the suit's capabilities significantly. However, given the complexity of the technology, we anticipate that the suit will be fully operational in approximately six months."
"Six months, huh? That's good progress. I want to make sure that the suit is not just functional but also adaptable to various combat scenarios. How's the adaptive functionality shaping up?"
"The adaptive functionality is on track. The nanobots will allow the suit to reconfigure its structure and properties in real time. This means it will be able to adjust its armor plating, enhance protection, or increase agility based on the immediate needs of the situation."
"Sounds promising. What about the energy management system? Can the nanobots help in optimizing and reallocating energy resources efficiently?"
"Yes, the nanobots are designed to assist with the suit's energy management. They will help in optimizing energy distribution and storage, ensuring that the suit maintains peak performance even under high-demand conditions."
"And the neural interface—how's the integration going with the suit's systems?"
"The neural interface integration is progressing smoothly. The nanobots will enhance the responsiveness of the interface, allowing for precise and immediate control over the suit's functions. This should provide you with seamless interaction and control."
"Good. I want to make sure we're on track for the six-month timeline. Let's schedule regular updates and run simulations to ensure the technology is performing as expected."
"Understood, sir. I will provide you with regular updates on the suit's development and initiate comprehensive simulations to assess the performance of the nano-technology under various conditions."
"Great. Let's keep pushing forward. We need this suit to be perfect."
"Certainly, sir. I will ensure that all aspects of the Mark 50 meet your standards and that we stay on schedule for completion."
The Mark 50 was progressing faster than he had anticipated. However, Tony's current focus was on a different project.
He was hunched over a workbench cluttered with vials, syringes, and various chemical compounds. Tony's eyes were fixed on a vial containing the serum—a vibrant, glowing liquid that held the promise of extraordinary power. He took a deep breath and picked up the syringe, his mind racing with the implications of this next step. The serum was designed not only to enhance physical strength, agility, and endurance but also to improve cognitive functions, making it a significant leap forward from the original version.
The super soldier serum, a project he had been pouring his efforts into, was taking shape. This new serum was intended to be a significant advancement over the one given to Captain America. Tony wanted to push the boundaries of human enhancement even further.
"This is it JARVIS, scan it and give me a run-down we will go over everything right now if it works out I am using it"
" The advanced biochemistry techniques and nanotechnology you've incorporated are showing positive results. The compound is exhibiting enhanced stability and efficacy compared to previous versions."
Tony nodded, his eyes scanning the data flowing across his lab's screens. The new serum was designed to offer improvements not just in strength and agility but in endurance, reflexes, and cognitive functions as well. He wanted a serum that would elevate his and Pepper's abilities to unprecedented levels.
"Good. I'm aiming for more than just physical enhancements. We need a serum that boosts cognitive functions too. The last thing we need is any mental side effects or diminished capacity."
"Understood. The current formula includes advanced neuro-stimulants designed to enhance mental acuity and reaction times. Rigorous testing is planned to assess the cognitive impact and ensure no adverse effects."
Tony paused, his fingers hovering over a control panel. He adjusted the serum's composition slightly, incorporating the latest refinements.
"And the safety protocols? I'm aware the previous versions had issues with side effects. I want to ensure this one has minimal risk."
"Safety is being prioritized. The serum includes gene therapy elements that should mitigate adverse reactions. Additionally, ongoing simulations are evaluating the serum's effects to ensure both efficacy and safety."
"JARVIS, bring up the real-time analytics and simulations for the serum. This will be the final rundown before I inject myself "
"Certainly, sir. Displaying the comprehensive data now."
The screen flickered to life, showcasing a complex array of graphs, charts, and dynamic data streams. The simulations were running various scenarios to test the serum's effects on Tony's physical and cognitive functions. Key metrics such as strength, agility, reflexes, endurance, and mental acuity were prominently displayed.
Tony watched as the data unfolded. The graphs showed a significant upward trend in physical strength and endurance, with peak values exceeding the anticipated thresholds. The agility metrics displayed a marked improvement, with the response times and maneuverability showing an impressive increase. Cognitive functions were also being tested, and the results indicated enhanced processing speed and mental clarity.
"JARVIS, give me a breakdown of the cognitive enhancements. I want to know exactly how this serum is affecting my mental functions."
"Analysing cognitive parameters. The serum has resulted in a 40% increase in mental processing speed and a 35% improvement in reaction time. Memory recall and problem-solving abilities have also been enhanced by approximately 30%."
Tony nodded, satisfied with the cognitive improvements. He then turned his attention to the physical metrics. The simulation was running a series of dynamic tests, including strength exertion, agility drills, and endurance challenges.
"How are the physical enhancements performing under stress conditions? I want to see how well the serum holds up during high-intensity scenarios."
"Initiating high-stress simulations. The serum is currently being tested under simulated conditions that include extreme physical exertion and rapid movement. Preliminary results show that the serum is maintaining optimal performance, with no significant deviations in strength, agility, or endurance."
The screen displayed a simulation of Tony engaging in high-intensity combat maneuvers. His virtual avatar performed with exceptional speed and power, executing rapid strikes and complex movements with remarkable precision. The data indicated that the serum was enhancing his abilities well beyond normal human limits.
"JARVIS, monitor for any potential side effects or anomalies. I need to be sure that the serum is safe and stable."
"Monitoring all physiological and neurological parameters. No adverse effects have been detected so far. The serum is stable and performing as expected."
"Give me the final review of the serum then"
"The final testing phase is complete, sir. The serum has shown remarkable stability and effectiveness. The cognitive and physical enhancements are well within the expected parameters, and the safety protocols have been validated."
"Alright, let's do this. Time to test it out,"
Tony carefully prepared the syringe and looked at her with a determined expression.
Tony injected the serum into his arm with practiced precision. The liquid coursed through his veins, and he felt a rush of energy almost immediately, his veins started to turn a bright blue color, and the color began to spread through all his veins even showing on his neck he gritted his teeth as his eyes widened and he collapsed on the floor.
A few hours later...
Tony jolted awake, drenched in sweat, disoriented and lying on the floor. As his mind started to clear, he propped himself up and immediately called out, his voice hoarse but commanding.
"JARVIS, how did it go?"
JARVIS's calm, ever-reassuring tone filled the room. "Sir, all systems are stable. The serum is performing within the projected parameters. I am monitoring your vitals and response in real time. Any anomalies will be flagged immediately."
Tony took a deep breath, still trying to gather himself. His body felt… different. Stronger. But before he could process it further, he heard a sharp intake of breath behind him. Turning around, he saw Pepper standing in the doorway, her eyes wide, staring at him in a mix of astonishment and—was that a glimmer of lust?
"Tony… what happened to you?"
Pepper asked, her voice laced with disbelief as she took in the sight before her.
Tony frowned, confused.
"What do you mean?"
Pepper approached him cautiously, her eyes scanning his frame. Normally, Tony stood at an impressive six feet, just an inch taller than her. But now, towering over her at 6'3", he looked... larger. His broad shoulders and chest strained against his shirt.
"Sir,"
JARVIS chimed in,
"it appears the serum has induced significant physical enhancements, including an increase in your height and musculature."
Tony blinked, still processing what JARVIS had said.
"What?"
He hurried over to the full-length mirror at the side of the room, eyes widening in shock at his reflection. His familiar features were still there, but everything else had changed. He was taller, his once lean body now packed with muscle. His T-shirt, once comfortably loose, now clung tightly to his chiseled frame. His arms, once toned, now rippled with strength. And there, staring back at him from his abdomen, was something he'd never had before—six-pack abs.
Without thinking, Tony pulled off his shirt, tossing it aside. He couldn't help but admire the transformation, his hand moving across his new, hardened physique. Muscular arms, a broad chest, and a defined core. He looked… incredible.
Pepper, still watching him from behind, couldn't hide her amazement—or her attraction.
"Tony, you're… different. I mean, you always looked good, but now…"
"I look fucking sexy"
He says with a smirk as he rubs his chin arrogantly.
"Pep, get ready. Now it's your turn,"
Tony said, his voice steady but carrying a weight of apprehension.
Pepper froze, her breath catching in her throat. Even though they had talked about this for weeks—discussed every risk, every possible outcome—hearing those words made it all feel terrifyingly real. She locked eyes with Tony, a flicker of shock crossing her face. He gave her a reassuring nod, though she could see the tension behind his bravado. He wasn't just her life partner; he was the man who had spent sleepless nights perfecting this version of the serum, doing everything he could to ensure her safety.
Taking a deep breath, Pepper steadied herself. She understood why this was necessary—needed—and not just for her safety but for the world's. The impending threats were too large, too overwhelming for her to remain in the background. She wanted to stand beside him, fight with him, and be an equal part of their future.
"Don't worry it is safe look at me I look amazing and the power and energy I feel is beyond anything I ever felt."
He tells her in assurance as she closes her eyes and lays down on the chair she feels a light sting on her arm and feels the liquid seeping into her she feels a rush of energy almost immediately, and her veins start to turn a bright blue color, the color began to spread through all her veins even showing on her neck she gritted her teeth as her eyes widened and she fell unconscious.
A few hours later
As the fog of unconsciousness lifted, Pepper gasped, her body jerking awake, drenched in sweat. Her chest rose and fell rapidly as she blinked, eyes darting around the room in confusion. The lab's familiar sterile glow seemed too bright, the sounds of the machines too loud. For a moment, she could only focus on the pounding in her chest, her heart racing like a drumbeat in her ears.
Her hand instinctively went to her arm, where she had felt the sting of the serum hours earlier. Her skin was cool and damp beneath her fingers, but there was no pain, no lingering trace of the injection. Yet, something inside her had changed—something profound and unmistakable.
"Hey, Pep, how are you feeling?"
Tony's voice cut through the chaos in her mind, grounding her.
She turned her head toward him, blinking through the disorientation. He stood by her side, his expression a mix of concern and hope, but there was a smile on his lips—a sign that things had gone as planned, at least from his perspective. He'd been sitting there, waiting for her to wake up, watching over her like a guardian.
"I... I don't know,"
she managed, her voice hoarse as she struggled to find the right words. She took another deep breath, trying to shake the lingering dizziness.
"I feel... different."
Tony's smile grew wider, though his eyes still searched hers for any sign of distress.
"That's good. Different is good. You were out for a while, though—scared me for a second there."
His tone was light, but she could hear the undercurrent of worry that had been gnawing at him.
Pepper pushed herself up, propping her back against the headrest. Her body felt oddly light, as if gravity had loosened its hold on her. Her senses were sharper too—she could hear the faint hum of the equipment more clearly than ever before, the subtle vibrations in the air. Her heartbeat, once frantic, was slowing, steadying into a rhythm that seemed more powerful than it had ever been.
She glanced down at her arms, watching as the faint blue glow in her veins faded back to normal. A shiver ran through her. The memory of the serum flowing through her, lighting up her bloodstream like electricity, made her heart skip.
"I remember the serum… my veins... it was like fire running through me. Then... nothing."
Tony nodded.
"Yeah, you were out for a few hours. Your body needed time to adjust to the serum. That blue glow? That was your cells absorbing the energy. You're... enhanced now, Pep. Stronger, faster, more resilient. But, I'd like to run some tests just to make sure everything's stable."
Pepper took another breath, deeper this time. She could feel it—the power that Tony had talked about before the procedure. It pulsed within her, not overwhelming, but present like an undercurrent just waiting to be tapped into. She flexed her fingers, watching her muscles react, more responsive than ever. There was a new ease in her movements, a fluidity she had never felt before.
"I can feel it,"
she said softly, glancing at Tony.
"The energy... It's like it's waiting to explode, but it's not... it's not out of control."
"That's the serum working,"
Tony said with a reassuring nod, stepping closer.
"It enhances everything, but your body's adapted to it better than I could've hoped. You're stronger now, Pep . And you look fucking beautiful come on look in the mirror"
he said, guiding her toward the full-length mirror at the edge of the lab. His grip was firm but encouraging, his eyes sparkling with anticipation as if he already knew what her reaction would be.
Pepper hesitated for a second, still adjusting to the sensations coursing through her body. Her movements felt different—more fluid, more powerful. As she stepped in front of the mirror, her breath caught in her throat. Her reflection stared back at her, and she gasped in shock.
She looked incredible.
The first thing she noticed was her height. She had grown, though only by an inch or so, but even that small difference made her appear taller, more commanding. Her posture was straighter, her frame slightly broader, but it was the subtle yet striking changes in her physique that left her breathless. Her muscles were more defined, sleek, and toned. She ran her hands over her arms, marveling at how strong they felt, at how sculpted they looked. There wasn't an ounce of excess—just lean, powerful muscle.
Her clothes, however, were not so fortunate. The fabric of her top had tightened across her chest and shoulders, the seams strained as though barely containing the new strength that surged within her. Without thinking, Pepper pulled it off, peeling the fabric away and tossing it aside, revealing the full extent of her transformation.
Her body was... stunning. She had always been fit, but now she looked like someone who could hold her own in a fight—someone who could take on the world. Her abs were defined, her waist narrow but strong, and her legs, visible through her leggings, were powerful and graceful at the same time. She moved her hand over her breasts and cupped them which had grown tremendously before she was a good C- cup but now she was a D-cup bordering E-cup they were huge.
"Those sweet babies aren't the only thing that grew just look at that ass"
He tells us her as he spanks her ass making her jump a little as she turns to look at her ass which had grown making her leggings tight and giving it an awesome look.
Lemon warning ahead
"Now why don't we give our bodies a test drive"
He asks her in a husky tone as he grabs her from behind pressing his bulging dick in her ass making her feel it as she smiles saucily and turns around putting her arms around his neck
"ohh what do you have in mind, Mr Stark"
She asks him innocently as she presses her crotch on his dick making him groan
"Well looks my secretary has turned into a naughty little slut after turning into the new CEO maybe I should discipline her"
He tells her as he grabs her ass with both hands making them sink in her ass they were jiggly but firm he pulls her closer as her boobs smash into his sculptured naked chest she was in a black sports bra which is now strained against them.
"Then please punish me, Mr. Stark, I have been so naught needy, and slutty you just have to punish me"
Her voice comes out huskily as she moans his name he pushes her down with his newfound strength forcing her to her knees she immediately gets to work unzipping his pants and pulling them down along with his underwear whipping his out dick which smacks her cheek making her go wide-eyed as she grabs hold of it with her hand she looked in astonishment his dick was bigger like really big and his balls had grown as well she cupped them she could feel the weight of his cum in them before he was 8 inches long and 3 inches wide but now he was 10 inches long and 4 inches wide making it a monster dick she gulped in fear and anticipation before she could say anything she feels a grab on her head as he holds her head and looks at her like an animal with primal lust and growls at her
"Ms. Potts I am going to punish you very roughly get ready"
And he forces his dick down her throat pushing the first 6 inches in one go as her throat is forced to expand and adjust to his new thickness he gives her a second to adjust and slams down his remaining length in her throat as he grunts making her gag and leak spit out of her mouth her throat had an outline of his dick as it expanded to adjust it she was leaking like a faucet down there as he claims her roughly making her love the rough sex as he uses her like a sex toy taking her as he wished he pulls her head back and pushes his dick in her again as he repeatedly uses her head and pushes his dick in and out of her mouth for a few minutes like that.
"Pep I am going to cum down your throat you better swallow it or you will be punished the whole night"
He shouts as she increases his pace as tears and spit is on her face and chin with a final slam he grunts and groans as he finally explodes cumming down her throat forcing her to drink it as her cheeks puff up and cum dribbles down from side of her mouth as she drinks his cum like a pro he doesn't stop cumming at all his load was far larger than it used to be but she wasn't the one to back down so she keeps drinking his cum as she felt her stomach fill up and after about 2 minutes he finally stops cumming and removes his dick as she coughs a little and takes deep gasps of breaths she couldn't believe just how much he had cum she could literally feel her stomach full it was filled with his semen and his cock was still standing there proudly before she could react he picks her up and slams her on the table tearing her leggings near her pussy which was totally soaked in her juices making her moan at the rough treatment there was no need for foreplay he slams his in her pussy pushing his whole length.
She felt his cock trying to bust through her cervix and into her womb he thrust into her wildly as he increases his pace this wasn't sex this was raw fucking and she loved it each thrust gave her toe-curling orgasm faster and harder she bucked her hips back against him intent on giving him the same amount of pleasure he was soon kissing her biting her neck leaving trails of marks on her body biting her nipples and he finally had found her G-spot and kept hitting it relentlessly as she tightly wrapped her legs taut around him as they both have animalistic sex, finally after some time he bottomed out in her both having an orgasm as he cums in her pussy and she squirts like a fountain shouting in a hoarse voice he cums in relentlessly non-stop filling her up to the brim directly pouring his thick cum in her womb filling her as the extra cum with no place to go leaks out of her and they finally stop.
Both lay down on the table side by side as they enjoy the aftermath of the orgasm
"That was fucking fantastic"
She says out loud making him chuckle as she gets up he once again tries to put his hand on her but she stops him
"Tony as much as I would like to continue this we need to get to work and take a few tests we also need to train to get used to our new bodies"
She tells him making him groan but agreeing that they have more important things to do.
