Chapter 2

"Sismhm... ter..." Adam spoke in between their hot and wet kisses.

"Mhmm...Yesh?" Zero Two responded, her voice breathless while her face flushed in a drunken red hue.

Adam kissed her lips for the last time before pulling her away from him. He looked at her beautiful turquoise misty eyes and said, "As much as I want to continue our joyous and exciting reunion, this is neither the time nor place to continue it. Besides, we need to get a proper bath or we could catch a cold."

Her brother's concern made Zero Two happy but she knew fully well that neither him nor her could fall ill to a mere cold. As a matter of fact, they were immune to a majority of diseases that usually affects humans.

Zero Two smiled cheekily as she licked her lips and leaned backwards, her bubble buttocks squishing against his chiseled waist.

"Very well, Brother." She narrowed her eyes at him, a lascivious look appearing on her face, "But this would only be delaying the inevitable." Saying so, she glanced behind her where she could feel a long and thick rod settling and wedging in between her butt.

"Oh, my.~" Adam mocked a worry but his face betrayed his words as it mirrored his sister's perverted expression.

"My sister had grown to be quite a temptress."

The two of them eyed each other with a predatory gaze, as if they were looking the most juiciest, tastiest meat in the world. Neither one of them were willing to stray from each other's gaze as their eyes glinted in twisted desire for on another. Viscous liquid began spreading on Adam's stomach whereas Zero Two could feel a long steel-like rod pushing in between her butt, but again, neither of them moved away. They were both playing fire, eager to see who would fall first.

Just as they were about to fall into their own world once more, someone interrupted them.

"U-um... Hello?!"

Finally, Zero Two and Adam snapped out of their trance and turned to the youth who had his back turned to them, seemingly looking away as to not peek on their intimacy. They didn't know if that was the case or the boy was simply shy to stare at their nakedness- which is understandably too much for a kid his age.

"Um... you are...?" Adam spoke to the youth while his sister looked at the boy in annoyance. She didn't like the fact that her emotional reunion with her brother, the event she had been wishing and dreaming for a long time, was being interrupted by this unknown background character.

"H-hiro!" The boy answered timidly. Since he had his back turned to them, he wasn't able to see the displeasure on Zero Two's face.

"Right. Hiro-kun. Thanks for your concern but if you're not going to come for a swim, then you should head back first. My sister and I will be back later."

Hiro nodded his head nervously. "A-Alright... but please don't take too long and take a proper bath in the dorm." Leaving behind this reminder, he began to walk away, but not before stealing a glance at the most beautiful man and woman he had ever seen. His gaze mostly stayed on the woman though since her chest was in full view as she sat on top of her brother. He was also too entranced by their appearance and inappropriately intimate actions that he didn't notice an important detail that Adam said.

As the youth continued to walk, he hesitated for a moment before turning around with closed eyes and flushed face.

"U-um. Your name! What's your name?"

The pair of siblings looked blankly at each other for a moment before the sister looked at the boy, still narrowing her eyes in annoyance, but answered quickly to get rid of his unwanted presence.

"Although we're parasites and we don't really have a name, my brother calls me Zero Two, based on my code number. Real creative, right?" She said with hint of sarcasm in her voice. Her eyes switching back to her brother as if he had wronged her.

"What? You love that name." Adam innocently rebuked.

Zero Two smiled warmly as she stared into his eyes, "...That's right. I do." she replied with a soft voice.

"I'm Adam." The young man nonchalantly added.

After hearing their answers, Hiro nodded to himself. But he soon felt as if he shouldn't intrude in their reunion any longer, so he decided to turn around and finally leave after getting their names.

'So her name is Zero Two huh?' Hiro found himself blushing when he remembered her womanly parts. '.....Wait a moment, aren't they siblings?'

Meanwhile, seeing the boy's figure disappear from the woods, Adam turned to look at his sister and admired her figure as she sat on top of him. He found himself mesmerized by her tall and slim body with an unblemished alabaster white skin that was similar to him. Not to mention her bountiful breasts whose peaks were covered by her pink hair, which only incited the hunger in him even more.

"I have to say, sister." He spoke with a wolfish grin. "You have grown to be quite beautifully... ravishing."

Zero Two snickered, as smirk adorning her face as she felt his intense, yet appreciative gaze roaming over her body. She trembled in excitement, subconsciously making her puff out her chest even more in pride as if to say, 'Look at these! Like what you see?'

The way she was presenting herself almost made Adam chuckle. It reminded him a lot when they were younger, where she would show something to him and expect to receive a praise or compliment.

'Ah... how I missed you...' Putting aside the horniness, he now truly felt complete with his sister right in front of him. Not just in a dream or a fantasy, but in reality.

And while Adam was 'wholesomely' relishing in their reunion, Zero Two on the other hand was practically restraining herself in place- lest she lets go of all her inhibition and pounces on her brother right then and there.

It couldn't be helped, okay?! I mean, look at his body!

Zero Two's eyes roamed from his chiseled eight pack with a perfect V-shaped torso, all the way to his immaculately handsome face. He looked so... so... sooooo tasty right now.

...Was she drooling? She was definitely drooling.

And as a matter of fact, she indeed was. She probably wasn't also aware of how perverted her expression was at the moment.

But the pink-haired girl was still in too deep her 'appreciation' of her brother's growth.

'Not to mention how little junior grew up to be big junior now.~' It had grown quite exponentially in comparison to when they were younger. Its shape was more defined, more beautiful, and definitely hotter than before.

She didn't doubt one bit that this big thing can effortlessly knock on her cervix now.

And her womb was trembling in excitement at the thought of that.

She hadn't realized it yet, but her wetness was becoming more and more prominent as her love juice began dripping down from Adam's waist and all the way to the ground.

"I could say the same to you." She purred while patting the thick and long rod that was stiffly wedging between her ass cheeks. She even gave it a few good strokes, feeling more giddy as her entire hand wasn't enough to grasp its thickness.

"Alright, This is enough." Adam decided to end the passionate reunion here because he could tell that his sister was seriously tempting him.

....And it was definitely working.

But no, he didn't want it to happen here. Don't get him wrong, he was more than willing to push her down right there and make her squeal his name until her eyes rolled to the back of her head. But not here in the middle of the forest where anyone could stumble upon their intimacy.

The sight of sister being fucked mindlessly was reserved for him and him alone. Plus, he doubt that he'd stop even if someone tried to separate them if he started now.

That's why, he raised his chest upward and sat upright, causing Zero Two slid down from his waist and land on his lap. Zero Two automatically wrapped her legs around his waist as she squished her body against him, not wanting to be separated for even single second.

The two stared at each other for a moment, not minding the fact that their most intimate places were touching each other. Adam grumbled inwardly, pushing away the urge to penetrate her right there and then, which was proving hard to do when he knows that she was more than willing to do it with him right now. His sister was like an irresistible temptress, attracting him like moths are to flames.

Be that as it may, as the responsible older brother, he had to control himself. He needs to use his herculean endurance! He didn't want his first union with his sister after a very long time to be in the middle of the forest, even if the two of them didn't mind it.

He does recall that one of her sister's fetishes was doing it outside. 'Hmm... maybe we'll do that sometime in the future but not today.'

After taking great amount of strength to hold himself back, Adam stood up from the ground with Zero Two grappling on his body like a koala, and brought the two of them back into the lake to cool down their heated mind and body.

"So, why were you bathing here?" Adam asked casually as he began to gently wash away any dirty mud or lint on Zero Two's beautiful and flawless alabaster skin.

"I wanted to swim in the ocean." She answered while reciprocating her brother's actions. She also carefully washed away the dirt and mud that stuck on his skin.

As she washed Adam's chiseled chest, she licked it and looked upwards as if appraising the taste. "Hmm... that's weird. I heard ocean water was salty."

"That's because this isn't the ocean." Adam informed lightheartedly as he brought water down to her hair.

Zero Two frowned as she pouted her cheeks. "I know that much."

Adam chuckled at his sister's spoiled reaction. She seemed annoyed for being treated like an idiot.

"Tell you what, I'll take you to see a real ocean someday."

Zero Two's eyes sparkled as her face visibly brightened. "Really?"

Adam smiled and patted her head. "But of course! Didn't I promise you this a long time ago?" He leaned forward and touched his forehead towards hers. Zero Two's turquoise eyes matching his deep blue ones as he said, "It might not be today, tomorrow, or the next following years; but I swear that I'll take you out to see the world someday."

His words made Zero Two lips twitch in excitement as she tried holding back from smiling like a fool. Her brother had always been like this, but it still meant a lot to her that he still remembered the promise he made to her when they were children.

And right now, saying such words right at their emotional reunion was like tugging the strings in her heart, making her feel indescribably warm and happy inside to the point that she feels like she was going to melt in his embrace.

"Mmmm!" Her lips pursed as she desperately tried to control the raging desire inside rising in lower body, but the hot steel-like rod resting between her legs, wedging between her lower lips, most definitely did not help. It was akin to slowly pouring oil into the fire, his desire to enter her was there, but he refusing to do the last step.

Meanwhile, here she was struggling to scratch an itch she cannot scratch. Just as she evidently trying to hold herself back, she noticed her brother watching her with an amused face, seemingly enjoying her plight.

"You!" She realized that her brother was doing this on purpose.

'Do you really think I wouldn't dare to attack you right here, right now?!' is what her eyes were telling him.

Adam chortled before finally relenting and pulling away from her. He had already teased her enough. Zero Two however, looked at him in dissatisfaction as she didn't want to separate from him, even if he was teasing her.

Seeing his sister's expression, Adam walked towards her pile of clothes, took her towel cloth and dried himself. "Look, I also want to do it with you right now but, let's go back and do it in our room, okay?"

"Really?!" Zero Two squealed in excitement as she rushed off the lake and stood beside him. "We'll really do that again after so long?"

As Adam affirmed with a grin, he added, "Not only that, but from now on, we can do it for as long as we want to. Whenever we want to!"

"REALLY?!" This time, Zero Two couldn't control herself anymore as she hugged her brother and planted kisses on his face.

Moving on, after Adam finished drying himself, he then began wiping his sister's body. Feeling the mildly damp towel gently drying her skin, a warm smile appeared on Zero Two's face as she reminisced about the kindness and care that her brother always does for her when they were younger. Inwardly though, she was trying her best to distract herself from being excited at the thought of doing those activities with her brother later.

"Mhm... Maybe I should stop teasing you now." Adam flirtatiously said as he looked at the dripping wet juice between his sister's legs. "I might get eaten alive later."

Snap!

Zero Two cupped her brother's cheeks and pulled him close, her turquoise eyes burning with desire and obsession. "You bet I will. Brother is my favorite flavor after all." 

'I love her so much.' Adam could only smile and flicked her forehead.

"Owie!" Zero Two pouted cutely while rubbing the pained spot. "How could you hurt your adorable sister!"

"Control yourself then." Adam deadpanned and pointed at his steel-hard dragon. "I'm just as eager as you, so let's go back first alright?"

"Oh okay, fine." Zero Two rolled her eyes but she couldn't prevent herself from smiling lewdly. Her lower lips was already dripping wet as she imagined the things they will be doing later.

'Not to mention at how big it has grown.' Zero Two peeked at her brother's anaconda that he was tucking in his underwear. 'Will it even fit me? No, I'll make it fit!'

Those were Zero Two's thoughts while wearing her clothes again, only to be surprised when she couldn't find her underwear.

"Huh?"

Adam noticed his sister's confusion and said, "What? Did you forget to wear panties? I thought you were already past that."

She had a habit of not wearing panties because according to her, 'it feels too stuffy'. That's why Adam was always making sure she wore one. While he did like seeing his sister's lower lips, that view was reserved exclusively for his eyes and his eyes alone.

Yes, he's twisted like that and he's aware of it.

"But I'm sure I wore one when I was here!" She didn't want her brother to think that she was still irresponsible at this age. Besides, she also began wearing it everyday from the moment she was separated from her brother.

"Really?" 

Zero Two nodded her head. "Yes, really!"

"Hmm... come to think of it," Adam's brows knit as he recalled something before his reunion with his sister. "I think I saw the boy earlier digging through your clothes."

"Ah! He was a pervert?!" Zero Two accused innocently.

Snap!

"I'll kill him." Adam's eyes gleamed murderously.

"Hehe..." Zero Two couldn't help but grin at her brother's overprotectiveness and obsession of her.

"No need to do that, brother. He's just a kid. Let him be with his fantasies."

"No one is allowed to fantasize my sister except me." Adam emotionlessly stated.

"Ah, brother. Don't you know being too overly obsessed can turn off a woman?"

"But you love it, don't you?"

"Yes." Zero Two admitted shamelessly.

Just then, the nearby bushes rustled as figures emerged from the woods.

Zero Two's face soured immediately as she looked towards the direction of the sound. "Too bad."

Her face lost all traces of joy as she reverted to inanimate face. "Times up."

Adam raised a brow at how quick his sister's face changed. He too, turned towards the woods and saw several military personnel approaching them, one of which was a tall and stocky young man wearing a parasite uniform. He had a long and strict face, while his height was just a little bit taller than Adam.

"We've been looking for you." The young man approached. His head was wrapped with a bandage, his eye had a patch, and his neck and arm had a cast. Adam couldn't help but wonder what happened to this youth.

"Why do you keep running off alone?" The young man said in exasperation as he stood in front of the two siblings.

Zero Two looked at the young man unfazed and said, "It's not like there's anything to do until tomorrow's welcoming ceremony."

The young man put her white cap back to her head. "Well, as your partner, I'm the one who suffers from it."

"Partner?" Adam spoke with interest. With his trademark angelic smile, he greeted the young man. "Thanks for taking care of my sister."

"Sister?" The young man looked at Adam in confusion for a moment before recalling an information the doctor mentioned before. "You are the special unit; Codenamed 'Adam', correct?"

"Yes." Adam affirmed and extended his hand. "Nice to meet you."

The young man nodded and shook his hand. "Likewise."

Zero Two frowned at their interaction as she looked at her brother and said, "He doesn't really take care of me, brother. He's just an uptight person who nags at me endlessly."

The young man groaned and rubbed his face in exasperation. "Well, I wouldn't be nagging at you if you would just behave, listen to orders, and stay in one place!"

"Hmph!" Zero Two pouted and looked away. She eyed her brother for a second before hugging him.

Adam just smiled and at his sister's spoiled attitude before wrapping his arm around her and patting her head.

"Well, then. Shall we?" The young man said while trying to act as if the sibling's interaction didn't bother him.

As they were traversing through the forest with Zero Two hugging her brother like a koala, Adam discreetly observed the escorts that was surrounding them. He took note of how guarded and vigilant the guards were despite how his sister managed to 'escape' their eyes.

'She probably has a tracker as well.' Adam maintained his amiable face despite the surging disgust that was bottling from within. He thoroughly hated the hypocrisy and evil plot of the organization ruling over them.

"So, any idea about why the doctor decided to have your unit to test-run here?" He asked the young man nonchalantly as if trying to make conversation.

The young man who had been discreetly glancing at them at every second, fixed his gaze to the front and said, "We aren't too sure either. Doctor only mentioned that he had a bad feeling about this place that APE wouldn't understand."

"Is that so?"

"Yes."

"And APE allowed this?" Adam asked while glancing at him.

The young man nodded. "This is Dr. FRANXX we are talking about. Of course, they gave him permission. Albeit-" He paused as he subconsciously glanced at Zero Two before looking away quickly. "It's nothing."

Zero Two didn't show any reaction to her partner's oddity. In fact, she hadn't been paying any attention or anything at all for that matter. Instead, she wholeheartedly immersed herself in the smell of her brother, the same comforting smell that makes her heart feel at ease and forget about everything else.

"Are you two really siblings?" The young man couldn't help but ask.

Adam smiled at his uncomfortable face and said, "Normally I would say that, that's classified information, but almost everyone knows about anyways. Kind of like an open secret of sorts." He looked endearingly at his sister and continued, "Before I was given the codename 'ADAM', I was normally referred to as Zero Three, which was my original code number."

"I see... And I heard that you are capable of upgrading a unit's performance to a marginal degree. Care to elaborate on that?"

It was that question snapped Zero Two out from her world as her brows knit and her pretty face frowned. Meanwhile, Adam looked at the young man and said, "Now that's classified information."

"I understand." The young man nodded in understanding and didn't mention it anymore. However, he did notice the change in his partner's face.

"Anyway," Adam changed the topic and asked, "What happened to you?"

The young man glanced at Zero Two. "She happened to me."

"Mhmmm..." Adam smiled while looking at his sister. "Lucky you then."

"Lucky?! Do you-"

The young man wanted to explain his grievances but as they exited the forest, a woman suddenly called out and ran towards them.

"Finally, They found you!" She had a tall, buxom body with a long, wavy red-brownish hair. She breathed a sigh of relief as soon she she saw both Zero Two and Adam.

"You... huff..." She was out of breath after searching for Zero Two for more than an hour. As she regulated her breath, she glared at Zero Two and said, "Why do you always have to make trouble for us?"

However, Zero Two acted as if she didn't hear her. Which was technically the truth since right now, her brother occupying her mind and blocked out everything else.

'Hehe... doing that with brother... hehehe....' A warm viscous liquid was starting to drop between her legs again. And since she was being piggy backed by Adam, her warm liquid ended up staining his back.

"Zero Two!" The woman frowned as she approached them. She looked at the young man who was being hugged by Zero Two and was momentarily taken aback.

She had heard of how beautiful he was, most especially his mesmerizing clear blue eyes and amiable smile. She even saw his photos before. However, seeing him in person was an entirely different experience.

"...."

"Hello, Miss...?" Adam put on his charming smile as he greeted the dazed woman.

"...U-uhm- Nana!" The woman blurted out her name in a fluster as she belatedly realized that he was asking for it. 'What the hell?! How can he be this handsome?!'

She didn't understand why meeting him felt like she was brought back to her teens, back to the time when she was a parasite and-

'And....' Nana frowned, feeling some blanks in her memories, which brought her confusion and unease. But before she could delve further into her thoughts, Adam's voice brought her back.

"Right, Nana. Nice to meet you. I'm-"

"Adam!" She answered excitedly, which she immediately regretted. Having no idea why she did that, she coughed out of shame and recomposed her stern face. "Adam." She repeated normally this time.

Adam smiled, going along with her act to save her from the embarrassment. "That's right. Nice to meet you, Miss Nana."

Just as he extended his arm for a handshake, he heard a genial laughter of an old man as he approached from the side. Nana, not missing this opportunity, immediately took his hand and shook it.

After that, Adam looked beside her and greeted the old man with a hunched back and balding head. Half of his face was mechanical, becoming his most prominent feature.

"Doctor." Adam greeted.

Dr. FRANXX acknowledge with a nod and said, "Zero Three... always the charmer, eh?" He teasingly elbowed the young man's arm. "I was just like you when I was in my prime."

Adam chuckled. "I believe you, Doctor."

Meanwhile, Nana had a face that said, 'I call bullshit', before dismissing the doctor's words and focusing on Adam.

The group proceeded to move towards the distant facility while Adam chatted away with Dr. FRANXX and the others.
