Chapter 1: Earth-Breeding Ground
DC Universe
Planet Earth [Smallville]
On a sweltering summer day at the Kent farm, Jonathan and Martha Kent decided to head into town to pick up some essential supplies, leaving their two new visitors behind.
Naru-To and Kara-EL, or perhaps Kara-To, share a unique connection as Naruto is her soul bond. Years ago, they crash-landed on Earth, having become ensnared in the gravitational pull of a star. This cosmic phenomenon not only boosted their Kryptonian abilities but also caused a significant delay in their arrival on Earth, landing them in a time far behind their original timeline.
Although Krypton was lost, there remained a glimmer of hope for its restoration, thanks to the efforts of both Naru-To and Kara's parents. They formed a partnership not just to protect their children, but also to revive Krypton.
Kara reflected with a hint of sadness that Kal-El had matured into an adult. Although it had been her responsibility to look after her cousin, he had established his own identity as "Superman," a name recognized by the inhabitants of this planet.
Kara chuckled to herself, reflecting on how, to the inhabitants of Earth, their abilities under a yellow sun appear almost divine. Fortunately for them, Kal-El is a noble and responsible individual rather than a tyrant. Instead of wielding his powers to dominate the planet, he chose to be its protector, even if not everyone views him that way.
"It's unfortunate that Kal-EL has matured without our guidance," Kara remarked while seated in a chair in the barn, sorting through Kal's old belongings. "However, he has adapted to his surroundings and may not grasp what actions are necessary."
Not far from Kara, on a bed in the barn, the sound of slapping flesh filled the area along with the feminine cries of a woman lost in her pleasure.
"Make sure to cum in her pussy, my love. Last time, most of your precious seed was in her ass," Kara said as she turned to look at the bed. The woman on the bed was around the same age as Kal, but her body looked younger with her firm C cup breasts and curvy figure. From how Naru was pounding her twat, she was tight. "We need to make sure that she is pregnant, after all."
The woman on the bed that Naruto was thrusting his mighty Kryptonian cock into was none other than Lana Lang, the childhood friend of his cousin and one of the future mothers of the new Kryptonian race.
Lana is a single mom to a daughter. After her marriage ended, her husband, who worked as a firefighter, lost his job, leading to a downward spiral in their relationship. Following their divorce, he disappeared, leaving Lana to take care of herself and her child alone. Fortunately, the tight-knit community in Smallville provided her with significant support from her neighbors.
"but there are some things they couldn't help with," Kara thought to herself with a smirk as she looked at Lana's well-fucked pussy and breasts filled with bite marks. Being a single mother raising a child alone after the father abandoned them is stressful to say the least, and when a young stud like Naruto showed some interest in her, she put up some resistance. But once they were intimate, all the pretenses vanished, and she showed her true face, a bitch that needed a good hard fuck.
Kara's mind went back to one of the encounters between Naruto and Lana. They had gone over to her house for dinner, and afterwards, while Kara looked after Lana's daughter, the woman was in her bedroom with Naruto, stuffing her full of his seed. That was two weeks ago.
Fast Forward
"So what do you think should be our next move?" Kara asked, looking at Lana. She was spread out on the bed, her pussy was leaking Naru seed, but from the amount, Kara was sure she was pregnant. "Other than breeding the women of this world."
"We need to practice our abilities and discover how to address our vulnerabilities," Naru-To reflected with a frown. Upon their arrival on Earth, he and Kara had been confronted by Batman, and the league believed they were aggressive extraterrestrial invaders. "Having a weakness to Kryptonite is such a ridiculous flaw."
Kara nodded, recalling how powerless a mere green stone had made her feel. She yearned to conquer that vulnerability, but she understood that it would be a challenging journey.
Flashback Scene Ahead
Gotham City
The initial sensation that overwhelmed Naru-To when he was abruptly awakened by the crash landing of the ship he shared with Kara was confusion. His senses were in disarray; he could see through nearly everything and was bombarded by sounds. It felt as though his ears were detecting every vibration, both close and distant, creating an overwhelming experience.
Naru-To let out a pained groan, but he soon heard Kara's voice next to him, also expressing her discomfort. This prompted him to struggle to open his eyes and glance sideways, where he found her curled up in a fetal position, cradling her head.
"This must be the influence of the Earth's yellow sun on us," Naru-To pondered, urging himself to endure the discomfort. "But it's nighttime," the Kryptonian man acknowledged, aware that they could potentially absorb solar energy even after dark. However, it shouldn't be impacting them so significantly unless they had encountered something else during their journey to Earth. "Concentrate, I need to concentrate."
Naru-To clenched his teeth tightly and concentrated on dulling his senses as he focused on Kara in front of him. To his relief, he managed to achieve this and swiftly knelt down, cradling her bare body in his arms.
"Quiet, just pay attention to me," Naru-To murmured gently, wanting to spare his beloved from any further distress by keeping his voice down. "Ignore the noise around you and concentrate on me."
Kara must have caught his words because her whimpering ceased, and she wrapped her arms around him, tears welling in her eyes as the harsh truth of their planet and people’s disappearance sank in.
"We need to get going," Naru stated, his instincts taking over. There was no place nearby where their crash landing wouldn't draw notice. "But first, we must retrieve the ship."
"You're right," Kara replied, though still feeling down. She hurried to their ship and placed her hand on it, with Naruto following suit. Before long, the spaceship began to shine red, disintegrating into stardust before reassembling into battle suits around the Kryptonian pair.
The idea for these suits came from Naru-To's parents; they designed them as a means for Kara and him to safeguard themselves in a dangerous environment. The suits feature self-regenerating AI developed by both the House of To and the House of El.
Naru-To's suit was adorned in red and gold, while Kara's was silver with gold accents, both featuring capes and having the symbol for the House of To on their crest that looks like a letter U. The AI system was designed to ensure their safety and manage their abilities on a planet orbiting a youthful sun.
The Kryptonian pair took off from the crash site, not realizing that a man in a bat suit had just arrived. As he observed them flying away, his eyes narrowed at the symbols emblazoned on their chests, prompting him to request backup.
"Clark, I believe we're facing an issue," Batman stated in his typical gruff tone, activating his utility belt to summon the Batmobile. "It seems we have two Kryptonians in Gotham."
"I'm en route," Clark Kent, also known as Superman, responded in a somber tone. His past encounters with his own kind had been far from positive, with General Zod being a prime example. "I'll also reach out to the others, just to be safe."
Fast Forward
"What?" Both Naru-To and Kara shouted in surprise as they heard their suit's AI explain their predicament. It seemed they had been stranded in space for an extended period, caught in the gravitational pull of a blue star. This experience had changed their bodies, enhancing their strength beyond what it would have been on Earth. The AI wasn't certain how much stronger they had become, but it was managing their power to prevent it from spiraling out of control.
"What are we supposed to do now? If the AI is correct, then Kal-El must already be an adult," Kara said with a heavy heart. One of her tasks on Earth was to protect her cousin, but if he is safe and has matured, he may no longer require her support.
"Yes, I believe your cousin is alright, but we should search for him just to be certain. However, let's not lose sight of our primary objective," Naruto said, receiving an affirmative nod from Kara. Their main mission involves planting the Kryptonian seed in the women of this world to ensure the continuation of their planet's legacy. Alternatively, if they can extract the Codex and recreate a genesis chamber, they might be able to revive their race in about twenty years. However, managing all those infants could be quite challenging, which is why impregnating the women of Earth seems like a more appealing option.
"Halt!" called out a man in a red and blue suit as he descended in front of Kara and Naru-To. Kara gazed at the emblem on his chest with curiosity. "Who are you both, and why are you here?"
Kara was speechless as she stared at the man bearing her family's emblem, who bore a striking resemblance to her uncle. Naru-To had already deduced that this could possibly be Kal-El.
"We mean no harm," Naru-To said, his suit converting his speech as he echoed Kal-El's earlier words. "I am Naru-To, and this is Kara-EL from Krypton. I believe you are Kal-El."
"How do you recognize that name?" Kal-El inquired, taken aback. He was aware that some Kryptonians were familiar with him due to his brilliant father, but this didn't appear to be the situation.
"That's simple, Kara. You're actually older than me, but because of some unfortunate events, you ended up on Earth before I did when it was supposed to be the other way around," Naru-To said, gently nudging Kara to bring her out of her daze. He understood how deeply she was affected by the loss of Krypton, and while he felt it too, he was managing to cope better, as his family was known for their resilience and strong will. "Why don't you go and greet your cousin?"
Kara gazed at Kal-El and instructed the AI to remove the mask from her face, which disintegrated into stardust and vanished into her suit, revealing her beautiful features.
Naru-To hadn’t mentioned it before, but now that he saw Kara, he noticed that she appeared more physically mature. Her body had the right amount of muscle while still maintaining a feminine shape, making her look like she was in her twenties. He, too, was in his twenties and had a well-toned physique. Both of them were about eight years old when they left Krypton.
As Kara approached Kal-El, Naru-To noticed more figures joining them. One was a man surrounded by crackling lightning, while another was identifiable as a Green Lantern, thanks to the records stored in his AI. Next, there was a Martian, which amusingly, his AI had information on as well. Then, he spotted a woman adorned with bracelets on her wrists and armed with a sword and shield at her sides, dressed in blue and red, prompting Naru-To to speculate if she was Kal-El's partner. The last figure was simply a man clad in a bat-like suit.
On the ground, Naruto observed as Kara embraced Kal-El, who appeared taken aback by the unexpected warmth of their encounter. It seemed he never anticipated their meeting would turn out to be so peaceful. However, Batman had other plans; the Dark Knight hurled a glowing green rock towards the two, and just before it reached them, they both fell to the ground, leaving Naruto in shock.
Superman and the other members of the league were taken aback by Batman's actions, but the Dark Knight remained unfazed. He viewed the two Kryptonians as potential dangers and was determined to imprison them until he could determine whether they posed any threat as invaders.
"What on earth is going on?" Naru-To shouted furiously as he soared towards Kara. His suit shielded him from the Kryptonite, and he noticed her face was pale, but she was starting to regain her strength the farther they moved away from the glowing mineral. "Put your helmet back on."
"What in the world were you thinking?" Green Lantern yelled at Batman. He was well aware of the man’s paranoia and eccentricity, but this was beyond anything he had seen. It seemed like things were finally about to resolve peacefully for a change.
"They pose a danger that we need to manage immediately," Batman said, as if it were clear. However, the other members of the League sighed at his reasoning, realizing that they would soon be facing a fight due to Batman's decisions.
In the meantime, Kara put her helmet back on and swiftly regained her composure. She shot a fierce glare at the man who had hurt her, then glanced over at her cousin with concern. Without hesitation, she soared down to remove the rock from Kal-El, but Batman intercepted her with explosives, blocking her path. This provoked Naru-To, and thus, the clash between the League and the two Kryptonians commenced.
Fast Forward
"I think we should talk things out," The flash said as he looked at the condition of his teammates and wince.
Batman was rendered unconscious after receiving a backhand from Naru-To, sending him crashing through several trees, and he hasn't moved since. Occasionally, Barry forgets that Bruce is just an ordinary human, and moments like this serve as a reminder of that reality.
Martian Manhunter has also been incapacitated; he attempted to delve into Kara's mind, but she responded aggressively, unleashing a solar flare that left the Martian unconscious.
Green Lantern lost his arm due to Naru-To's blue heat vision, unlike Superman's red version. Barry had to rush him to the Watchtower, hoping that his arm could be reattached later.
Diana found herself facing the two Kryptonians by herself when Barry took his injured teammates back to the Watchtower for medical attention. Despite her extensive experience, she struggled against the fury of the two Kryptonians and ended up ensnared in her own lasso of truth.
Naru-To and Kara weren't unscathed; they had numerous healing cuts across their bodies, and their suits were damaged yet in the process of self-repair. With the sun about to rise, things were about to escalate dramatically.
Superman, weakened by Kryptonite, struggled to crawl away from its grasp, completely unaware of where Bruce had discovered such a substantial chunk of it. Barry would have attempted to help Clark by removing the Kryptonite earlier, but the two Kryptonians had been aggressive towards anyone who approached Superman. He assumed they were trying to shield him, believing they would harm Superman just like Batman would. So, Barry resorted to his usual strategy: engaging in conversation with his adversaries.
"The rock over there is known as Kryptonite, and it's harming Superman, so it would be wise to relocate it away from him," The Flash said, causing Kara to glance at her weakened and pale cousin. She had been so concentrated on dealing with the immediate danger that she hadn't noticed Kal-El's condition.
"Darn it," Kara exclaimed, grabbing the Kryptonite and hurling it with such force that it incinerated as it ascended beyond the Earth's atmosphere.
Kal-El gradually regained his strength; although he felt feeble, the rising sun began to revitalize him. As he surveyed the chaos that could have been prevented had Batman not acted as he did, he let out a deep sigh of frustration.
Clark approached his cousin and chose to find out if she was open to having a conversation to address their issues amicably. Fortunately, she was receptive, which complicated matters further since he now needed to convince the league—the same individuals who had just gotten there asses kicked by Kara and Naru-To—to agree to remain on Earth for the foreseeable future.
Flashback Scene End
"For now, we train and grow," Naru-To stated as he flew over to Kara, still naked from his 'fun' with Lana. As he reached his mate, he claimed her lips in a heated kiss, which she returned.
"I long to have your child right now," Kara said sorrowfully, her forehead resting against Naru's. "But we can't do that until we figure out how to separate the Codex from you."
"I understand, I also want to witness your belly expand with our baby," Naru expressed. He felt just as heartbroken as his partner, but as long as he carried the Codex, they would have to avoid starting a family. "Since the Codex is inside me, my sperm contains Kryptonian material rather than my own DNA, which means I could father children with many women, but none of those children would actually be related to me."
"We need to figure out how to detach you from the Codex without harming you," Kara expressed with frustration. She longed for a child, but understood that she had to wait since, in Naru's current state, any baby conceived from his seed wouldn't be genetically his.
"One day, we'll figure it out," Naruto said quietly. Jor-El had implanted half of the Codex in Naruto and the other half in Kal-El, though Superman was unaware of this, and they had no intention of revealing it to him. "However, we'll need a genius like Jor-El to help us."
Kara proposed, "We could attempt to utilize the Kal-El ship's AI," but she was aware that this wouldn't be effective. The AI was primarily designed to be loyal to Kal-El, so although she might gain access to it, it would ultimately inform Kal-El, jeopardizing their future plans.
"That could be a viable option, but Kal-El may start to have doubts about us," Naru-To remarked, to which Kara agreed, adding, "It's unfortunate that Kal-El has turned out to be such a letdown."
"I understand what you're saying," Kara replied, a frown on her face. They certainly respect Kal-El; he’s a hero and a genuinely good person. However, he possesses the other half of the Codex, which is crucial for the survival of half of their race. "He should have at least fathered a few children by now."
Naru-To agreed and his hand wandered over Kara's body. He had to restrain himself from wanting to have a child with her; her smooth stomach would look wonderful with a baby developing within. However, he needed to remove the Codex from himself first. But before that, he planned to father as many children as he could with various women.
The Codex was not assigned to Kara due to her being female, which limits her to carrying only one child at a time. Conversely, she would need multiple males to fertilize her eggs, while he and Kal-El are capable of impregnating numerous women at once.
"According to our expectations, the children will initially have a blend of Kryptonian and human genes, appearing human at first. As they develop, however, they will begin to show Kryptonian powers, and eventually, their Kryptonian lineage will prevail, making them 99 percent Kryptonian," Naru-To said while cradling Kara in his arms. She responded with a soft hum, understanding that they were taking these measures to ensure the survival of their race, regardless of whether extracting the Codex from Naru-To is impossible, or if it can be extracted but ultimately rendered ineffective.
"Yes, but we have to be ready for what's to come," Naru-To stated. He knew that while he had more control over his powers and while he was in fact stronger than Kara, he had only just tapped into a fraction of his full potential. "I think meditation, combat training, and testing to see how powerful we are exactly is in order."
Kara sighed at Naru-To's words; she adored her partner, but he had a penchant for combat. His entire family had been part of the Military guild during their lifetimes, and he was determined to uphold their legacy. She braced herself, knowing she would feel sore afterward, and not in an enjoyable way.
Fast Forward
Washington DC
Kara and Naru-To soared through the sky, clad in their superhero attire. Naru-To's face was fully visible, while Kara's outfit left her midsection and face uncovered. Below them, they observed an intense battle where Wonder Woman was facing off against a towering woman resembling a giant feline.
"Should we step in to assist her?" Kara inquired, observing Wonder Woman battle the villain. They were present because the Justice League wanted at least one of their own monitoring them while they were out in the field.
Kal-El, also known as Clark in his human guise, would be the one to handle this situation, with the occasional secret involvement from Batman, who had placed surveillance devices on the Kent farm. However, they promptly removed the listening devices, not concerned about the potential anger it might provoke in the overly cautious Dark Knight.
"Nah, she's got it under control," Naru-To said, glancing over to see a towering woman with red hair hurl a building at Diana and the woman with cat features. "But I think it wouldn't hurt to help out; I'll catch the building while you take on that giant lady."
"You simply don't want to strike a girl," Kara playfully teased her partner, fully aware that it wasn't accurate. Naru-To had been trained by his mother, who would come back from the grave to give him a serious beating if he ever considered holding back just because his opponent was a woman.
"Haha, that's hilarious," Naru-To remarked with a hint of sarcasm as he and Kara soared toward their target. Naru-To managed to catch the building that was hurled at them, while Kara delivered a powerful punch to the giant woman's face, causing her to stumble backward.
Once the two villains were defeated and the citizens were rescued, Naru-To, Kara, and Diana departed from the scene and soared above the city in search of any criminal activity, but it turned out to be a rather uneventful day.
Naru-To and Kara soared through the sky alongside Diana, who led the way. They utilized their x-ray vision to glimpse beneath the Amazon's attire, and they were delighted by the thought that she would be an excellent mother to the emerging Kryptonian lineage. However, they realized they couldn't act on their feelings just yet, as they lacked the experience to handle any potential backlash from the Amazon if she responded negatively to the notion of becoming a mother.
"I doubt she's very fond of me," Naruto mused with a grin. His initial encounter with the amazon hadn't gone particularly well, and then she suggested taking Kara to train on her lesbian island, which both of them turned down. Kara refused because Naruto couldn't join, and Naruto thought it would be pointless since their suits' AI contained combat knowledge from the house of To, tailored for Kryptonians. Training there would be a waste of time.
It was amusing when she attempted to claim that Kara lacked the ability to manage her powers to transport her to Themyscira. However, Naru-To simply pointed out that Kal-El, being a Kryptonian, would be the most qualified to explain how to control their abilities. Additionally, their suits help regulate their powers, meaning they actually have a better grip on their abilities than Kal-El does.
Naru-To couldn't help but smirk as he observed the expression on Diana's face when he highlighted the weaknesses in her reasoning, leading to their assignment with the Kents and Kal-El for training. "It seems like she's not accustomed to hearing 'no,'" he thought.
"The princess looks like she hasn't been with a man for a long time," Kara said to Naru in Kryptonian. She was using her x-ray vision to look between Diana's legs as they flew behind her. "I am sure she is a screamer."
"You are probably right about that," Naruto said as he too was looking through Diana's clothes. "Her pussy looks so tight and surprisingly pink; I would love to have a go at her."
As the Kryptonian duo conversed, Diana couldn't grasp their words, but she sensed their discussion revolved around her. She suspected they were employing their x-ray vision to scrutinize her, and she felt they were interested in her for more than just one reason.
Diana sighed inwardly, wishing that the two Kryptonians were merely driven by desire rather than having any hidden agenda to dominate the planet. They were conversing in an unfamiliar language and casting her a familiar, lustful glance. If they were simply a couple of lecherous individuals, she thought, that would be manageable—after all, the world is already filled with people like that. However, if they turned out to be disguised conquerors, it would create a significant headache. "Hera, just let them be a couple of horny fools," she mused.
Chapter End
x-x-x-x-x-x-x-x-x
A/N: Naru-To and Kara are now on Earth, focused on attracting women, starting with Lana Lane. They've also taken notice of Diana, but she might be a bit overwhelming for them at the moment. So, who should they pursue next? Should it be Wonder Girl, Lois Lane, or some ordinary civilians? I might create a poll to decide which woman the mischievous duo targets next, depending on the outcome or a commission. Alternatively, I could leave the choice up to whoever commissions the chapter. I hope you enjoy this installment—take care!

Isn’t she old though?

For the pairing, I just named random women in the end, it doesnt have to be Lois and for not telling superman about the Codex is because he might tell someone like batman and who knows what he would do if he found out Naruto is planning to breed and recreate Krypton on earth, not to mention if Lex or some other super villain found out, so for now they are keeping the Codex secret.
God of Wind 200
Why not Blackfire and why Superman’s girlfriend? And wouldn’t it just be easier to explain to Superman that he has the codex and what it does because I mean from a standpoint it’s not wrong unless they were rapping the women but since they are not I don’t see the problem
Alterfiction21
Martha kent would be a hot choice
