Chapter 1

Dr. Ben Smith stood alone in his dimly lit home lab, the hum of machines and the sterile scent of antiseptic filling the air. His hands hovered over the vial, a small 30ml container of clear fluid that held the culmination of years of research, sleepless nights, and a gnawing hunger for something beyond the boundaries of mere science. Nanobots. Billions of them, microscopic and invisible, but with the potential to reshape flesh, bone, and everything in between.

He lifted the vial, the glass cold against his fingers. His blue eyes, sharp and focused, scanned the label—nothing but a blank white strip where there should’ve been traceability markers. That was the point. This batch was off the record, acquired through channels that didn’t ask questions. For the first time in years, he felt a rush of excitement. This was more than another step in medical advancement. This was about control—the kind he had sought in the back rooms of high-end brothels, when he paid for an hour, or two, of a woman’s submission. But even then, the power was fleeting, their bodies imperfect, their reactions disappointing. This ... this was personal. He wanted to create perfection. And once he did, he would own it.

The technology had already saved lives—curing cancer, repairing damaged organs, even regenerating tissue—but that wasn’t enough for him. The nanobots could do more. They could be reprogrammed, reshaped—not just to save lives but to fulfill fantasies, create perfection where nature had failed. He imagined it—the power to make a body anything he wanted. The curve of a breast, the length of a cock, the strength of a grip, the sharpness of a jawline. The possibilities were endless. This wasn’t just about healing; this was about domination over flesh, bending biology to his vision, an urge beyond professional curiosity. It was personal, even sexual in its raw hunger for control.

He had always been fascinated by control, by the idea that he could manipulate life down to its very essence—reshape it to his will, as if he were a god with the power to define perfection. Medical advancements were only the beginning. He wanted more. Not just to fix the broken parts of the body, but to sculpt them, bend them into shapes and forms that suited his desires. The thought made his pulse quicken—a hunger deeper than science, something primal, bubbling beneath his calm exterior.

He set the vial down on the stainless steel counter and reached for the syringe. His hands were steady, practiced, as he pulled back the plunger, drawing precisely 3ml of fluid into the syringe. The tiny machines floated within, waiting for his command.

A sharp beep from the scanner on his desk broke the silence. He placed the syringe under the scanner’s green light, watching the screen blink to life. A serial number flashed across the monitor as the nanobots were assigned a unique identification code. Behind him, the holographic display began to flicker, a faint outline of his own body taking shape in the air.

The terminal buzzed softly as the nanobots were linked to the system. He tapped a few keys, watching as the screen showed a live feed of their neural network forming, threads of light weaving together in intricate patterns. It was beautiful, in a cold, clinical way—like watching the creation of a new organism, except this one was under his control.

His fingers danced across the keyboard, entering directives. The commands flowed easily, a product of years of trial and error, of knowing exactly how far he could push this technology without it collapsing into chaos.

He straightened, syringe in hand, staring at the sharp needle glinting under the lab’s LED lights. A slow smile crept across his face as he positioned the tip against his forearm. There was a moment, just a brief pause, where he considered the enormity of what he was about to do.

Then he pressed down. The needle slid in easily, and he depressed the plunger, sending the nanobots coursing into his bloodstream.

He exhaled, feeling a slight warmth spread from the injection site, the bots beginning their work. His eyes flicked to the holographic display, where his body slowly rendered in soft blue light. It was a mirror image, down to the last detail. He could see the nanobots inside of him now, each one represented as a tiny spark of light in his veins.

The replication process had begun.

His workstation beeped again, displaying the rapid multiplication of nanobots inside his system. Hundreds of thousands turned into millions within minutes. Neural pathways were forming, syncing with the terminal in real-time. His fingers tapped through the directives again, shaping the commands with a clarity that came from months of planning.

He leaned back in his chair, watching as the holographic model became more vivid, more alive. Every muscle fiber, every bone, was replicated within the hologram with perfect precision. Soon, he thought, it would be time to test the limits of what these machines could do. But for now, he felt the power coursing through his veins, the tingling at the base of his spine as the nanobots integrated with his nervous system.

A low chuckle escaped him. This was only the beginning.

He leaned over the glowing console, watching as lines of code danced across the screen, reflecting in his sharp blue eyes. This was his magnum opus—the program that could rewrite the human body as easily as a few keystrokes on a terminal. Nanobots had always been limited, confined to fixing isolated parts of the body. A tumor here, a damaged organ there. But the human form was a tangled web, complex beyond measure. One wrong move, one error in calculations, and the consequences could be catastrophic.

It was that complexity that had driven him. It consumed him, late nights for years. He had built a system that could handle the intricacy of it all, one that could take a single command—reshape the body, modify it—and break that command down into thousands of precise subroutines. The program didn’t just tell the nanobots to heal or adjust; it told them how to do it without disrupting the fragile balance of the human body.

He stared at the holographic replica of himself floating in the center of the room. The nanobots inside him were active now, alive, their neural network connected to the terminal. They responded to the program, awaiting orders. His heartbeat quickened. The possibilities were endless.

Smith had loaded every medical text he could get his hands on into the system—every study, every trial, every procedure known to man. The AI that ran the program could analyze, synthesize, and adapt in ways no human mind could. It could understand the body in its totality, mapping out every nerve, every cell, and ensuring that even the slightest change was accounted for. But the mind ... the mind was still beyond him, its layers too intricate for the current technology. He couldn’t control thoughts, but he could control desire. He smirked, thinking about how addiction—how pleasure—could do what science could not.

There were limitations, of course. Mass couldn’t just be made to disappear. He couldn’t simply shed weight like peeling off a layer of skin. But repurposing? That was a different story. His mind churned with the possibilities—body fat broken down, rebuilt into muscle; organs strengthened and optimized. Height? A few inches could be added, using the fat stores in his body as raw material. It wasn’t magic, but it was close. The nanobots could take what was already there and make it something new.

He had run simulations countless times, testing the program’s capacity to handle entire bodily transformations without failure. Every time, the system responded flawlessly, recalculating in real-time, adjusting subroutines on the fly to prevent complications. But simulations were one thing. Doing it on a living, breathing body was another.

He’d worked too long, given up too much, to let this be just another theoretical triumph. He had the power to reshape himself, to break through every biological limit nature had imposed. His eyes flicked to the screen again, the directive panel blinking, waiting for his input.

All he had to do was type.

Smith stood in front of the holographic display, his fingers dancing over the terminal. A full body scan, the first real test of his nanobots’ capabilities, flickered to life. The outline of his body glowed in sharp detail, every bone, muscle, and organ rendered with clinical precision. His heartbeat, his neural activity, even the smallest shift in body temperature was displayed in real-time.

The scan began. His eyes narrowed as lines of data flooded the screen, dissecting him down to his genetic code. He felt a familiar thrill—a mixture of excitement and anticipation, the same feeling he’d had as a young researcher breaking new ground. The thrill of discovery, of facing the unknown and conquering it.

It didn’t take long for the system to start flagging issues. They were small, but they were there. He wasn’t perfect. No one was. A few broken strands of genetic code in his DNA, mutations here and there. Some inherited, others accumulated over the years. His immune system was handling a couple of low-grade viral infections, probably just picked up by day to day activities. Nothing dangerous, but they weren’t supposed to be there. His eyes—well, they’d seen better days. Age had slowly dulled his vision, and though he hadn’t noticed it much, he certainly wasn’t seeing the world as clearly as he used to.

Nothing life-threatening, but annoying. Imperfections. Things that could be fixed.

He pulled up the diagnostic list. The neural network inside his body mapped every anomaly, every tiny flaw in his genetic code, his immune system, and his organs. Subroutines were already generating on the terminal, hundreds of them, each dedicated to a specific task. The nanobots would repair the broken DNA, eradicate the infections, reset his immune system to optimum performance, and restore his vision. He smirked at the thought of seeing the world with sharper eyes—20/20 vision, maybe even better than that.

He clicked the command. The screen blinked as the directives were set into motion. The terminal displayed a countdown: 5 minutes until full correction.

His body remained still, but he could feel the faint warmth spreading through him. The nanobots were working, traveling through his bloodstream, targeting each flaw with microscopic precision. The sensation wasn’t unpleasant; it was more like a low hum vibrating through his muscles, a subtle shift just beneath his skin.

For a few moments, nothing seemed different. He continued staring at the holographic image of himself, watching as the subroutines completed one by one. DNA strands were being corrected, piece by piece, the viruses being wiped from his cells, Unwanted bacteria flushed from his system. Then he blinked, and suddenly, the world in front of him sharpened.

The dull edges of the lab’s equipment became razor-thin lines. The lights overhead no longer blurred in his peripheral vision. Everything snapped into crystal clarity. He could read the smallest text on the terminal from across the room, every character sharp, vivid. His eyes were working better than they ever had.

The warmth in his body intensified slightly, spreading from his core out to his limbs, but still, no pain. Just an odd sensation of being hyper-aware, of every part of him humming in unison with the nanobots as they corrected him from the inside out.

As the countdown hit zero. Smith grinned, an unrestrained sense of satisfaction washing over him. It worked. Every anomaly, every imperfection, scrubbed clean from his body. God damn...

He stepped closer to the holographic display, the image of his naked form suspended in glowing light. At 52, he was relatively average on most accounts. It was time to take things further, to move beyond simple corrections. He brought up the details pane, eyes gleaming as the stats of his physical body appeared on the screen. Height: 5’11. Weight: grayed out—mass, unchangeable. Body fat: 22%. Muscle mass: average. There were dials, sliders, and numbers, all there to be manipulated with the swipe of his hand.

He paused for a moment, staring at the body fat percentage. His fingers twitched as he dragged the dial down, watching the fat melt away in the holographic projection. The number dropped lower, 15%, 12%, finally stopping at 10%. As the body fat lowered, a red negative weight number appeared beside his body mass. The system needed to repurpose the fat, turn it into something useful. He grinned, sliding the muscle mass dial upward, feeling the anticipation coil inside him as his body in the display bulked up. Broad shoulders, thicker arms, sculpted chest—every inch of muscle finely tuned, precision-crafted. He added two more inches to his height, watching as the negative mass zeroed out, leaving just a half-pound of matter left.

But there was something else. Something he had been thinking about, fantasizing about, ever since he got his hands on the nanobots. He shifted his gaze to his dick. The display showed it too, hanging slightly above average in both length and girth. 6.5 inches, 5 inches thick. A decent size. He was hard now, the thought of what he could do sending blood surging through his veins. It showed in the display, the outline of his erect cock hovering in the air before him.

His pulse quickened as he highlighted his cock, along with his testicles, the faint glow surrounding them on the display. Time to have some fun. He grabbed the slider, dragging it upwards slowly. The length grew first, the hologram showing his cock elongating inch by inch, the girth expanding to matChapter 7 inches. 8. He finally stopped at nearly 9 inches long, with a thickness of 6.5 inches, his balls hanging lower, fuller, heavier. The sight of it made his breath hitch, a wicked grin spreading across his face. That would work. For now. He already knew he’d tweak it later, make it bigger when the mood struck him.

Satisfied, he hit the apply button. The terminal buzzed softly, calculating, the screen flashing with lines of code as it generated thousands of subroutines. The estimated completion time blinked on the screen: 15 minutes. His heart rate spiked in excitement. No waiting. He would feel the transformation now, in real-time.

A deep warmth surged through his core, stronger than before, spreading out into his limbs. His muscles tensed and then relaxed, a rhythmic pulse echoing under his skin. The transformation had begun, and he was awake to feel it. He watched the holographic model on the screen as his body reshaped itself in real-time. Veins sparked with nanobot activity, tiny glimmers of light flashing inside him, rippling just beneath the surface. His pulse quickened, matching the thrumming heat that moved through him like a living current.

Smith inhaled sharply, feeling the muscles in his arms thicken. There was no pain—only a steady pressure, as if his body was inflating from the inside out. His chest expanded with each breath, the muscles becoming more defined, skin stretching over newly formed ridges of muscle. His fingers twitched involuntarily, power surging through them. His legs elongated, bones shifting and reforming smoothly, adding inches to his height. A subtle shift in perspective as the lab seemed to tilt slightly—he was taller now, his body recalibrating instantly to the new height. He glanced down at his reflection in the steel countertop, catching sight of his growing chest and broader shoulders. Then the sensation moved lower, heat pooling in his groin. His cock swelled, inch by inch, throbbing with vitality as it thickened and lengthened. His balls grew heavier, their weight pulling on his skin as they expanded. He let out a low chuckle, watching the transformation happen before his eyes, feeling every change without discomfort, only satisfaction.

He stood still, his breath steady but his body alive with sensation. His muscles flexed involuntarily, responding to the nanobots as they rewired his form. His biceps bulged, veins surfacing like rivers, thickening with every second. The feeling was intoxicating—control, power, reshaping himself into something superior. His fingers brushed against his chest, and he could feel the hardness of muscle that wasn’t there minutes before. His skin, warm and taut, stretched perfectly over his newly sculpted form. Each breath seemed to fill him with more strength, more precision. Below, his cock pulsed, now heavier and larger than ever before. The girth filled his hand as he tested it, feeling the weight, the incredible power. He grinned wickedly, watching the final adjustments in the hologram. The replication was flawless.

The muscle definition was sharp, each curve and line more pronounced than before. His abs were solid, his arms thicker, and his height ... He could feel the extra inches, his posture more commanding. He looked down, grinning as his eyes landed on the most obvious change—the length and thickness of his cock hanging heavy between his legs, the weight of it making his pulse quicken with satisfaction. He had known it would work, but seeing it—feeling it—was something else entirely. He looked like an enigma, like he was in his mid thirties, yet somehow still seasoned, where someone could perhaps say he was in his mid forties.

He lingered in front of the mirror, his fingers tracing the hard lines of his chest, marveling at how seamlessly the nanobots had reshaped him. Every muscle rippled beneath his skin, every joint moved with a fluid strength he hadn’t felt in years—if ever. His reflection grinned back at him, and he couldn’t help but laugh, low and satisfied. This was power. This was control.

The night stretched on, and the thrill of his transformation didn’t fade. He wandered through the house, his footsteps heavier, more deliberate. Each movement was effortless, his new strength humming under his skin like a coiled spring ready to snap. He stretched his arms above his head, his muscles tight but not aching, enjoying the way his body responded.

Eventually, exhaustion tugged at the edges of his excitement. Not physical, but the mental weight of the night’s intensity. He collapsed into bed, his mind still buzzing with possibilities, his body thrumming with the lingering effects of the transformation. Sleep came quickly, a deep and dreamless slumber that seemed to stretch into eternity.

When he woke the next morning, the sunlight spilling through the blinds, his body felt ... different but familiar. The changes were now a part of him, woven into every fiber of his being. He moved with ease, swinging his legs over the edge of the bed and standing up with a confidence that felt natural.

It was Saturday morning. He had the whole day to himself. He wandered through his house in nothing but his boxers, stretching his limbs and feeling the new strength with every movement. He poured himself a cup of coffee, savoring the bitter warmth as he sat in his living room. The possibilities swirled in his mind. He was just beginning to tap into the power of the nanobots, the potential to reshape the human body—reshape anyone’s body. The thought made his pulse quicken again.

Eric had been his connection to the underworld, a man with access to flesh—women, broken by life, waiting for someone to use them. Smith had started out as just another client, paying for his nights of indulgence, trying to scratch that itch for control. But it wasn’t enough. He wanted more than submission. He wanted to change them. Their relationship had grown in strange, mutual benefit—Smith got his subjects, and Eric never asked what he did with them as long as the money was right. Over time, though, their relationship had evolved, especially once Smith began to share details about the nature of some of his research.

Eric was intrigued, of course. The kind of man who saw opportunity in everything, especially in the potential to control bodies, keep them healthy, and to reshape them for pleasure or profit. They’d had more than a few conversations about what the nanobots could do. It hadn’t taken much to convince Eric to let him start experimenting. When the time was right, Eric had promised, Smith could have his pick of any girl of his he wanted.

He leaned back in his chair, sipping his coffee, thinking about the girls. Some had been fun, some forgettable. But Lizzy—Lizzy—she had stuck out. Tall, slim, with curves that caught his eye. Her body was perfect in a raw, untouched way, but his mind wandered to what it could become. With a few adjustments, a few calculated tweaks, she could be even more stunning, even more ... useful. She would be the perfect subject, not just for science, but for something more primal that simmered just beneath the surface of his thoughts. And she had a way of moving, a light in her eyes that had drawn him in, and a bubbly sluttiness he enjoyed. He smirked, setting his coffee cup down.

He grabbed his phone and quickly typed out a message to Eric: I want Lizzy over this afternoon. 2 o’clock.

It didn’t take long for the reply to come through: Done.

Smith sat back, smiling to himself. He’d fucked plenty of women through Eric, used their bodies in whatever ways amused him for the night. But this—this was different. Those women had been experiments of a different kind, playthings. Lizzy, though? Lizzy was special. Today would be interesting. Lizzy would be his first real test, the first woman whose body he could truly reshape. And unlike those hollow transactions with Eric’s girls, this time, he would keep her—perfected, and under his control.

He leaned forward, his tablet glowing softly on the coffee table. His fingers moved with practiced ease, accessing the program’s AI section through the terminal in his basement lab. The interface lit up, sleek and responsive, and with a few taps, he entered the nanite neural network, opening an audio channel directly to the AI. This allowed him to directly ask questions to the AI controlling the nanites neural network within his body.

“Regarding sexual function—can you enact a change that will allow the subject to maintain an erection and only ejaculate when desired?” he asked.

The AI’s voice responded smoothly, calm and clear. “Yes, easily. This change is quite minor. Shall I enact it now?”

A flicker of satisfaction ran through him. “Yes.”

There was a slight pause as the system processed, and then the AI continued. “Change enacted. Is there anything else you’d like to modify?”

Smith stared at the tablet, the gears in his mind turning. “What’s the current volume of semen released during ejaculation?” His tone was clinical, but the excitement simmered beneath the surface.

“The figure varies depending on multiple physiological conditions,” the AI answered, “roughly 2 to 4 milliliters of fluid is released during ejaculation.”

Smith nodded, thinking. That wasn’t going to cut it for what he had in mind. “And how much semen is currently stored within the testicles?”

“Maximum capacity is roughly 5 milliliters.”

His lips curved into a smirk. This was just the beginning. “What’s the feasibility of multiplying that by 10?”

The AI paused for a brief calculation. “Some minor reworking of bodily functions and testicular size will need to be completed, but the modifications are feasible.”

“Do it,” Smith commanded without hesitation. “And make all sperm produced dormant.”

“Directives sent,” the AI confirmed in its steady, neutral tone. “Roughly 2 minutes until completion.”

Smith exhaled, leaning back into the couch, a sense of power swelling inside him. He grinned, thinking about Lizzy, the way she’d respond when she arrived later that afternoon. The new changes would make this encounter unlike any before.

Lizzy

Lizzy arrived right on time, her usual bright smile lighting up her face as she bounced through the door. Just as she reached for the handle, her phone buzzed again. Leo. She frowned, seeing his name flash on the screen along with missed calls and unread texts. Lizzy, where the hell are you? Call me back! She bit her lip, hesitating for a brief moment. The protective tone in his last message made her chest tighten. She quickly silenced the phone and shoved it back into her pocket, ignoring the gnawing guilt.

“Hey, Dr. Smith!” she said cheerfully, her voice as sweet and bubbly as ever. “You look great! How’ve you been?”

Smith nodded, a small smile tugging at the corners of his lips. “Doing well, Lizzy. Come in.”

She practically skipped into the room, her energy infectious. “Ooh, what’s on the agenda today?” she asked playfully, her hands already moving to unbutton her coat.

“I’ve got something to show you,” Smith said, his voice low, a hint of something more beneath the casual tone.

Lizzy’s eyes lit up. “Show me? I love surprises!” She giggled, stepping closer. “So, what’s this thing you wanna show me?” Her fingers danced over the buttons of his shirt, quick and eager. She was used to this, falling into the rhythm of her job easily.

Her hands slipped lower, undressing him with practiced ease, her bubbly commentary filling the air as she worked. But the moment she pulled down his pants, her eyes went wide. “Oh my gosh!” she gasped, her hand freezing over his swollen cock. “I don’t remember you being this big!” Her laugh was light, innocent, but there was genuine surprise in her voice as she stared at him, clearly impressed.

Smith’s smirk deepened, watching her reaction with quiet satisfaction. “I’ve been running a few experiments lately,” he said, casually adjusting his stance. “And there’s a few I want to try with you too.”

Her eyes brightened at the word ‘experiments.’ She always had a playful, curious streak, especially when it came to something new. “Really? Like, you’re gonna use science on me?” She sounded excited, not nervous, as she tugged her shirt over her head, her tone laced with innocent eagerness. “This is gonna be so fun!”

Her fingers traced along his chest as she giggled, stepping out of her skirt without hesitation. “I can’t wait to see what you’ve been working on,” she said, her bubbly enthusiasm never wavering. “I mean, if it made you this big...” She shot him a playful glance, biting her lip. “I’m so ready to be your experiment.”

Lizzy’s eyes glimmered with playful curiosity as she knelt before Smith, her lips curling into a teasing smile. “Let’s see just how much bigger you’ve gotten,” she giggled, wrapping her delicate fingers around the thick length of him. Her hand barely encircled his cock. Slowly, she began stroking him, her movements gentle but firm, eyes flicking up to meet his as she leaned forward.

She licked her lips before teasingly flicking the tip of her tongue against his swollen head. Smith’s body tensed, but he stayed silent, watching her with calm intensity. She giggled again, clearly enjoying the reaction, before taking him deeper, her lips stretching around his girth as she slid his cock into her mouth.

Lizzy’s bubbly, innocent exterior made every movement seem more deliberate, more exploratory. She bobbed her head slowly, her tongue swirling around his shaft with practiced skill, but there was a wide-eyed enthusiasm in the way she did it. Her lips slid further down, inch by inch, her hand still stroking what she couldn’t take into her mouth. The wet sounds filled the air, her soft hums vibrating against him.

Smith groaned low in his throat, his fingers resting gently on her head, guiding her without force. She worked him eagerly, her pace quickening as she grew more comfortable with his size. Her eyes flicked up again, locking with his as she pulled back, lips still wrapped around the tip before she slid down again, taking him as deep as she could, her hand moving faster now.

“Fuck, Lizzy...” he muttered under his breath, feeling her lips tighten around him. She smiled around his cock, her own arousal building as she sensed his pleasure. She didn’t stop, sucking him harder, taking him deeper until her throat flexed around him. Her pace was relentless, the sounds of her mouth and his heavy breathing filling the room.

But just as Smith’s muscles began to tense, he pulled her off him with a gentle tug. She looked up, slightly breathless, her lips wet and swollen, a question in her eyes.

“Not yet,” he said, his voice firm but teasing.

Her eyes widened with excitement, and without a word, she stood up, quickly stripping off the last of her clothes. She was eager, that much was clear, her innocent charm never fading as she lay back on the couch, spreading her legs invitingly. “Okay, your turn,” she giggled, her voice light but filled with anticipation.

Smith positioned himself between her legs, his cock hard and heavy as he slid the tip against her wet hairless pussy. Lizzy moaned softly, her hips already rolling upward to meet him. He teased her for a moment, running the head of his cock along her wet folds, slick with anticipation.

“Please...” she whispered, her bubbly tone slipping into something more needy, more desperate. “I want it.”

He thrust forward, burying half of his cock inside her with one smooth stroke. Lizzy gasped, her back arching off the couch as she felt every inch of him stretch her. Her legs wrapped around him, her heels pressing into his back as he started to move, slow and steady, pulling almost all the way out before driving back in. Her moans grew louder with each thrust, her hands gripping the cushions beneath her as her body adjusted to the sheer size of him.
