Chapter 2

The next morning, as the early light filtered through the windows, Smith’s phone buzzed on the kitchen counter. It was Eric.

How’s the experiment going? the text read, short and to the point, as always.

Smith smirked as he tapped out a reply: Great. You should come over later this morning. I’ve got something to show you.

He hit send, leaning back in his chair, sipping his coffee as he thought about the night before. Lizzy had been more than he could’ve imagined, her body perfectly molded to his desires, her every moan, scream, and gasp the result of his careful planning. The changes he had made to her, and to himself, were everything he had envisioned. And he knew Eric would be impressed.

Lizzy was still asleep upstairs. After the marathon of sex they had indulged in, her body was completely worn out. The nanobots had done their job perfectly—enhancing her stamina, making her more sensitive to every touch—but even with those enhancements, she had passed out completely spent.

The sound of footsteps on the stairs broke through his thoughts. He glanced toward the stairwell as Lizzy appeared, gloriously nude, her body still flush with the afterglow of last night’s pleasures. She hadn’t bothered with clothes; she loved the way her skin felt, bare and open, knowing it drove him wild. Her large breasts bounced with each step, each one a reminder of her perfect transformation.

“Good morning,” she said, her voice sleepy but cheerful, a soft smile tugging at her lips. She stretched, her arms raised above her head, showing off the curves of her newly enhanced body. “God, I feel amazing,” she giggled, her eyes still half-closed as she made her way into the kitchen. “I don’t think I’ve ever slept so good.”

Smith grinned, watching her with a sense of satisfaction. “You certainly earned it,” he said, standing up and walking over to her. He grabbed her by the waist, pulling her close for a brief kiss. His hands wandered down to her hips, feeling the firmness of her body, the results of all the changes he’d made.

Lizzy moaned softly into the kiss, pressing her body against him. “Mmm, you weren’t kidding about those experiments,” she teased, her fingers grazing over his chest. “I’m still sore ... but in a good way.” She giggled again, clearly enjoying the way her body felt.

Smith smirked. “I’ve invited Eric over later this morning. I want to show him the results.”

Lizzy’s eyes widened slightly, a flicker of uncertainty crossing her face. But then it passed, replaced by a familiar excitement. “Oh really?” She giggled again, a playful grin spreading across her face. “I can’t wait to see the look on his face when he sees this.” She cupped her massive breasts, giving them a playful squeeze. Smith watched her, knowing that her eagerness was more than natural.

The nanobots enhanced her physical pleasure, rewiring her body to crave his touch. She didn’t know it yet, but she was already addicted—compliant, not because he controlled her thoughts, but because she needed the satisfaction only he could give.

Lizzy stretched, her body still glowing with satisfaction as she rubbed her stomach. “I’m starving,” she giggled, looking over at Smith. “Got anything for breakfast?”

Smith’s mind was already drifting downstairs, where his latest idea was waiting for him in the lab. The syringe he’d prepared last night sat there, gleaming in his thoughts, urging him back to work. He glanced up at Lizzy, her carefree humming breaking the silence. “Why don’t you make us something?” he suggested, his tone still calm but now tinged with distraction. “I’ve got some work I need to finish in the lab.”

Lizzy smiled and nodded, turning toward the kitchen. “Sure thing, Doc! I’ll whip up something good.” She started opening cabinets, humming to herself as she moved around, completely at ease in her nakedness.

As she reached for a pan, her phone buzzed on the counter. Her stomach tightened when she saw it was another text from Leo. “Lizzy, seriously, where are you? You need to call me. I’m worried.” She bit her lip, hesitating for a moment before locking the phone without replying. She couldn’t deal with his overprotectiveness right now. Not when she was so deep in Smith’s world. Pushing the thoughts of Leo aside, she focused on cracking eggs into the skillet, letting the sizzle drown out the guilt gnawing at her.

Smith headed downstairs to his lab, his mind already spinning with ideas. The incident from last night—his nanites replicating inside Lizzy through his semen—had sparked something. A new idea. As he entered the sterile lab space, he quickly set to work, prepping another syringe of nanites. This one would be for Eric. He knew Eric well enough to know that, once he saw the results on Lizzy, he’d want in. He’d want the power, the control.

But Smith wasn’t going to hand that power over so easily.

He scanned the syringe, assigning it a serial number, his eyes narrowing in thought. With the incident last night, he knew there was a way to use this situation to his advantage. His fingers tapped the screen, pulling up the AI interface. This time, he spoke aloud. “Can nanites that are released into another individual via sperm be automatically reprogrammed with certain directives within their new host?”

The AI processed for a moment, then replied: Yes. Once nanites are transmitted to a new host, they can be reprogrammed remotely with predefined directives.

Smith grinned. “Good,” he muttered to himself, the plan solidifying in his mind. It was a brilliant delivery method. Eric would think he was gaining full access to the nanite technology, but Smith could control exactly what those nanites did—and more importantly, what they couldn’t do.

He would give Eric the sample, let him enjoy the benefits, but the real power would still rest with Smith. And every person Eric fucked would receive pre-programmed “upgrades,” controlled not by Eric, but by Smith’s system. It was the perfect way to spread the nanites without ever losing control of them.

Smith’s smirk deepened as he closed out the interface and carefully set the syringe aside. Eric will never even know.

Sitting down at his terminal, his fingers flew across the keyboard as he began writing the code that would control the batch of nanites meant for Eric. The syringe sat nearby, gleaming under the sterile lights of the lab, ready to be injected, but not without the proper programming first. Smith’s mind raced, thinking through every detail, every contingency.

He started simple. The first subroutines were familiar—he had used them on himself and Lizzy. Complete health optimization: any genetic disorders, viral infections, and diseases would be eradicated. Full immunity to future ailments. These were the basics, the foundation of what the nanites could do. But Eric wasn’t just going to be content with good health.

Smith smirked as he added the next line of code, adjusting the nanites to increase the size of Eric’s cock by 50%. He knew this wasn’t what Eric really cared about—what Eric wanted was power. Control. But Smith needed to throw in a few indulgences, a distraction, something to keep Eric satisfied while Smith retained the true power in their arrangement. It was subtle enough not to arouse suspicion, but significant enough for Eric to feel like he’d gotten his money’s worth. That should do.

Satisfied with the personal enhancements, Smith turned his attention to the secondary part of the plan: the auto-programming for the women Eric would inevitably fuck. This was where Smith’s control would be truly felt. He quickly copied over the same health and immunity subroutines—no harm in ensuring the girls were at their physical peak.

Then, he added something special. A 50% increase in breast size for every woman Eric came into contact with. It was a small but noticeable change, just enough to make them more visually appealing, more “enhanced” without making it seem obvious. Next, he set the parameters to increase their sensitivity in key erogenous zones—their nipples, clits, G-spots, all heightened for pleasure.

Smith paused for a moment, reviewing the code. He knew Eric well enough to know the man would get greedy eventually, wanting more control, more changes. “That’s where I come in”, he thought, smiling as he added a final line of code. For any additional modifications, Eric—or the women—would have to come directly to Smith. There would be no unauthorized tampering, no bypassing the system.

Smith leaned back in his chair, satisfied. Perfect. The batch of nanites was now pre-programmed, ready to be delivered. Eric would think he was getting exactly what he wanted—better health, a bigger cock, and a way to enhance the women he slept with. But the real power would stay firmly in Smith’s hands.

Smith came back upstairs to the smell of sizzling bacon and eggs, catching Lizzy gliding around the kitchen, still bare-skinned, her curves on full display, humming sweetly to herself. When she noticed him, her face lit up with a grin. “Hope you’re hungry!” she giggled, sliding plates onto the table like everything was just normal, as if she wasn’t dripping wet and glowing from last night.

Smith slid into his chair, his mind stuck downstairs, the syringe, the code he’d been perfecting—but he pushed it aside. No sense in ruining the mood. They ate in a comfortable quiet, Lizzy occasionally bubbling over with talk about how fantastic she felt, how last night was something else entirely, her voice bright and carefree, almost vibrating with energy.

As they finished eating, Lizzy’s playful energy lingered in the air. Her eyes flickered back to him again and again, a growing heat behind her gaze. Her fingers absently traced the curve of her stomach, then lower, a hint of something more bubbling to the surface. Each glance toward him spoke volumes—she wasn’t done with him yet, not by a long shot.

She leaned in, voice hushed but thick with desire. “I don’t know what you did to me, Doc,” she whispered, licking her lips, “but I can’t stop thinking about last night ... I’m so fucking horny.”

Smith chuckled, stood up, and shrugged his robe off without a word. His cock dropped free, hanging heavily between his legs, and Lizzy’s eyes went wide. It was bigger—massive. The head looked almost swollen, thick with blood, pulsing like it had a heartbeat of its own. “Oh my fucking god...” she breathed, her voice shaky as her hand reached for it, fingers twitching with need. “You’re ... even bigger than before!”

Without another thought, Lizzy dropped to her knees, mouth open and ready, but she could barely fit half of him inside. Her lips stretched tight around his shaft, saliva pooling at the corners as she tried to take more. “Mmmph!” she moaned, gagging slightly, pulling back to work him with her hands, stroking what her mouth couldn’t handle. Her eyes flicked up, glassy with lust, her tongue tracing the underside of his cock. “So biiiiiig,” she gasped between wet, desperate slurps, spit dribbling down his length as she pumped him harder.

Smith groaned, his hand settling on the back of her head, feeling her throat fight to take him deeper. “You can barely get it in,” he muttered with a smirk, watching her struggle, her moans vibrating against him, adding to the sensation.

Lizzy gasped, pulling off with a pop, her chest heaving, hands still working him eagerly. “I’m trying!” she giggled breathlessly, her excitement barely contained. “You’re just ... so big!”

But Smith wasn’t finished. He yanked her up, spinning her toward the couch and pushing her back, her legs spreading wide on instinct. Her pussy was glistening, practically begging for him, and when he pressed the fat head of his cock against her slick entrance, she let out a loud, quivering moan. “Fuuuuuck,” she gasped, her body trembling as he started to push in.

He slid in slowly, her pussy clenching tight, struggling to stretch around him. “Oh my God,” she whimpered, her nails digging into the couch cushions as he buried himself deeper. “You’re ... you’re so fucking biiiiiig ... I can feel it, fuuuuuck!”

Smith kept pushing, inch by thick inch, her pussy gripping him like a vice, her breath coming in shallow, ragged bursts. “Fuuuuuuck,” she moaned again, her back arching, tits bouncing as he filled her completely. “You’re too big, I can feel every inch ... fuuuuuuuck!”

He didn’t stop. He shoved deeper, feeling her walls struggle to accommodate him, her body shaking as he finally bottomed out inside her, buried to the hilt. “Oh my God,” she cried out, her voice breaking. “You’re stretching me so much, I can feel every ... fuck!”

Smith grinned, pulling back slightly before thrusting into her again, slow but deep, savoring the way her pussy fought to take him. Lizzy moaned louder with each movement, her body writhing beneath him, a slave to the pleasure he had engineered.

“You love this, don’t you?” he growled, grabbing her hips tighter, slamming into her harder.

“Yesssssss!” she screamed, her voice cracking with pleasure. “Fuck, yessssss, I love it!”

She did love it—more than anything—but only because her body had been reprogrammed to crave his touch like a drug.

The more she had, the more she needed. “Stretch me more, pleaseeeee!”

He pounded into her, her moans turning to frantic, breathless cries as her body bounced beneath him. Her tits jiggled with each thrust, her hard nipples brushing against his chest, sending jolts of pleasure shooting through her. He reached down, squeezing her breasts, twisting her nipples, making her scream louder. “Oh fuuuuuck, I’m gonna ... I’m gonna cuuuuum!” she gasped, her whole body shaking uncontrollably. “You’re too big ... I can’t ... fuuuuck!”

Smith grinned, slamming into her even harder, pushing her right to the edge, until she finally screamed, her entire body locking up as her orgasm crashed over her. Her pussy clenched hard around his cock, milking him as they came, her legs shaking, her back arching off the couch as she cried his name.

Lizzy collapsed, panting and trembling, her body slick with sweat, barely able to move. Her mind spun with the lingering pleasure, a haze clouding her thoughts. She couldn’t think clearly—only feel. And all she felt was need. But then came a knock at the door.

Smith pulled out slowly, watching Lizzy’s body tremble and twitch, still spasming with the aftershocks of her orgasm. The room was silent except for their heavy breaths—until a sharp knock at the door broke the moment. His smirk widened at the sound. “Go answer that,” he ordered, his voice low with amusement.

Lizzy blinked, her post-orgasmic haze barely clearing as she wobbled to her feet. Her legs shook with every step, still slick with the evidence of their morning. “Like this?” she giggled breathlessly, her voice hoarse with exhaustion and thrill.

“Exactly like that,” Smith said, his tone firm, commanding.

Lizzy didn’t hesitate, her naked body glistening as she made her way to the door, pussy still slick and swollen. She opened it, revealing Eric standing there, his eyebrows lifting in surprise before a slow, knowing grin spread across his face.

“Well, well,” Eric chuckled, his eyes trailing up and down Lizzy’s naked body. “Looks like you’ve had quite a morning.”

“She’s ready to show off the work,” Smith called from behind her, stepping into view, still nude, his cock still half-hard. “Come on in, Eric. You’re gonna love what I’ve done.”

Eric strode into the room, eyes fixed on Lizzy’s naked, glistening body, chest still heaving, skin flushed from her recent orgasm. The sight stunned him, but he wasn’t complaining. A grin crept across his face as his gaze slid over to Smith, who stood there with a smug smirk.

“So this is where your experiments led?” Eric chuckled, voice dripping with intrigue as he sank into a nearby chair, reclining like he was ready for the main event. “Not bad, Doc.”

Smith’s grin widened, his hands wrapping around Lizzy’s hips as he guided her back to the couch. No words were needed as he bent her over, ass high in the air, her body completely exposed to the two men. Lizzy moaned, low and soft, arching her back, her hands clutching the couch’s edge, waiting, trembling with anticipation.

“Let’s show Eric just what upgrades you’ve gotten,” Smith muttered, cock already stiff as he positioned himself behind her. He spread her legs wider, soaking in the view of her slick, swollen pussy, still glistening from earlier. Without missing a beat, he slid the head of his cock along her wet folds, teasing, making her squirm, her hips pushing back desperately.

“Please,” Lizzy gasped, voice shaky and breathless. “I need it ... I want it so bad.”

Smith glanced at Eric, who watched, eyes dark, hunger in his stare. Then, with a rough grunt, Smith drove into her, his thick cock stretching her all over again. Lizzy screamed, her back bowing as she slammed back against him, nails digging into the cushions.

“Fuuuuuuck,” she cried, body quaking with each powerful thrust.

“Still so tight,” Smith growled, hands gripping her hips harder as he started pounding into her. Each thrust was deliberate, rough, sending her body rocking forward, ass bouncing with every savage slam of his hips. Lizzy’s moans grew louder, desperate, as her body surrendered to the onslaught.
