Building the Ultimate Fuck Doll – Chapter 2

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.
