Chapter 15

As soon as dinner was finished, Zero Two immediately dragged Adam to their room, much to the disappointment of the other teens since they wanted to ask him many questions. Like, how was he able to operate a FRANXX like that? How long has he been a pilot? Has he fought any klaxosaurs? If so, what's the worse one yet? Etc. etc. Long story short, the young minds of the teens were brimming with curiosity.

Well, that was mostly the case with the girls along with some of the boys, mainly Goro and Futoshi. Zorome was too busy trying to fix his pride by drowning himself in his own fantasies/delusions while Hiro, ever the despondent and gloomy boy, was wallowing in his own monologues upon his recent failure.

What's funny here is that in the back of his mind, the gloomy boy was actually thinking that the results could've been different if Zero Two had been his partner. Of course, he only kept this thought deep in his heart and was never going to say it out loud.

Fast forward to midnight, Adam and Zero Two was disturbed in the middle of their lovemaking by a series of soft knock from the door to their room. To be honest, the sound was barely heard over Zero Two's loud and lewd moans, but Adam's keen ears picked up on it.

"Someone's at the door." Adam grunted in a low whisper behind Zero Two's ears as he plowed her from behind. His husky voice sending shivers down her spine, making her snatch tighten explicitly as if to not let him go. Which in return, caused Adam's words to quiver with a groan.

"I'll go... check... who it is..." Adam spoke in between his thrusts. Really, it was difficult to keep a straight mind whenever he was balls deep inside her. Most especially when she was holding his full mast with a vice grip.

Literally, her pussy was strong like that. And he certainly wouldn't have it any other way.

Zero Two on the other hand, furrowed her brows in displeasure, but it was immediately wiped away as Adam knocked on her womb repeatedly.

"Hn!~~" The sexual accumulation that's been building up for quite some time, ended up being released with Adam's incessant thrusts deep inside her pussy. She ended up cumming and Adam unsheathed his long and girthy sword from her hot, wet snatch. When he did so, a copious amount viscous liquid squirted out of her gaping snatch, spraying all over Adam's crotch and wetting the bed.

Losing strength over her body, Zero Two flopped on their bed face first, completely delirious from her intense orgasm, while Adam left her to rest as he went towards the door, wondering who could be disturbing them at this time.

"Who is it?" He didn't even bother covering himself up as he opened the door.

He was mostly expecting it to be Nana to nag at them again.

He wasn't going to lie, but flustering the older buxom woman was very amusing for him. His antics with his sister most of the time was to see her reaction.

....Or so Adam would like to claim but in reality, he and his sister simply lacks self control.

Anyway, to his mild surprise, his eyes looked down to see a petite brunette that only reached until his chest. Zero Two was tall for a girl, but even she only reached until Adam's chin. He gazed at his cute blushing partner who wore a cute pink nightwear. Adam smirked as he noticed the way she was squeezing her legs together like she was enduring something in her lower body. It was clear that she had been listening in on them for quite some time.

'Did I turn her into a voyeur?'

"Naoms?"

"A-Adam..." Naomi's shy and bashful face was tinted in beetroot red. When she looked at him, her eyes widened in surprise to see Adam completely naked. Her eyes trailed down from his broad chest, to his chiseled abs, then all the way to his crotch where she saw his anaconda brimming with life.

'I-It's really big....' Even if she had seen it for the second time, she still couldn't help but gasp in awe of how Adam was carrying such a big thing between his legs.

When she realized that she was staring again, Naomi put her gaze back to Adam's face, only to see him smirking at her in amusement.

'Oh Papa, that smirk.... damn it!' Naomi felt tingly all over again. 'Why is he so handsome?!'

"Do you want to come in, or are you just going to stand there?" Adam teased.

"I-I-I'll..." Naomi fumbled her words, feeling embarrassed for being caught staring.

"Well?"

Naomi took a deep breath to gather her composure and eventually answered, ".....I'll come in."

Adam smiled as he swung the door wider, allowing Naomi to enter before closing it. When Naomi entered the room, she was assaulted with the strong scent of sweat and... something fishy. The windows were shut, which explains why the smell was trapped inside. Naomi couldn't quite describe the smell, but she didn't find it unpleasant. Rather, it was terribly arousing.

Naomi gulped. She then saw Zero Two laying on the bed with her face first while her butt was sticking upwards, still standing on her knees. Tears could be seen from the corners of her half-lid eyes, an expression that Naomi immediately understood as overwhelmed from ecstasy. Naomi thought she was imagining it, but she swore she could see very faint steam coming out of Zero Two's clean shaven red snatch as milky-white liquid dripped out and fell to the bed.

"Beautiful, isn't she?" Adam suddenly spoke from beside Naomi as if admiring his work.

Naomi noticed him glancing at her from the side. She could see his mesmerizing crystal blue eyes were brimming with amusement and possessiveness as he looked at her, which somehow aroused her even further. Smirking at her, Adam then walked to the bed and nonchalantly sat on the edge.

"I'd invite you to take a seat but..." Adam smiled wryly.

He didn't need to explain since Naomi could see that there was nowhere else to sit that didn't have traces of their messy and intense love making (bodily fluids), something that Adam didn't feel ashamed about.

What can he do? His sister loved making a mess in their love nest. Something about their scent mixing together and marking every place they could gets her off so much. And Adam, ever the caring and loving brother he is, indulges her in her kinks.

"You can sit beside me, if you want." Adam said, wanting to tease the blushing brunette.

To his surprise however, Naomi actually went and sat beside him.

His brow rose for a moment as he then asked, "Well? What does my cute partner need for you to visit us this late at night."

"....." Naomi didn't respond as she hung her head low, wanting to hide the embarrassment on her face. Unfortunately, her ears betrayed her as they were also tinted in red.

Although Adam already knew what the innocent-turned-corrupt brunette partner of his, he still wanted her to state her wish herself. He also didn't mind waiting for her since his sister would take about four minutes or less to recover from her intense orgasm.

"...A-Adam...."

"Yes?"

"I... I need your help."

"What's wrong?"

Naomi placed her hand on her chest as she took a deep breath and spoke nervously, "Ever since I saw you and Zero Two do the 'forbidden acts' in the bathroom... I've been feeling very strange." she reveals, "The entire day, all I can think about is that scene between you two and I couldn't focus at all. Even when we fought in that spar."

Adam remained quiet as she continued, "What's worse is that... my... m-my pussy...."

She almost coughed, finding the term to her special area to be quite embarrassingly lewd...

Pushing through her embarrassment, she continued, "I-It's been feeling so strange... like there's a throbbing inside that I couldn't comfort no matter what I tried..." Naomi looked at Adam and asked, "Is this called 'Sexual Excitement'? I remember you mentioning it before."

"Ding! Ding!" Adam playfully jokes, "You're correct! Too bad there's no prize."

"I see..." Naomi nodded in understanding, although her cheeks were still red.

After a moment, she asked, "A-And for me to stop feeling it... I need to 'orgasm'? or 'cum'?"

"Right again~"

"Please, help me." Naomi resolutely said as she turned her face to him. Adam met her eyes and he could see that she was truly bothered by the strangeness in her body and her lack of control over it.

The natural root cause for this was hormones. Since her sexual hormones were mostly kept suppressed, Adam's introduction of sexual education as well as letting her experience it, felt like breaking a great dam that's been accumulating over the years. The pleasure she's been deprived of from all of her life, suddenly started erupting at the moment of when Adam introduced her to this new world.

A world full of pleasure and ecstasy.

Naturally, her hormones were relentlessly going crazy. She's a teenager after all. Coupled along with Adam's constant teasing and the stimulation of showcasing the bare naked mating process between a man and a woman. Naomi's female instincts have been awoken.

(A/N: I am the author and I say this is scientifically accurate.)

In short, she was in heat.

And she needed a release, very badly.

Adam couldn't help but shake his head inwardly once again.

'At this point, I really can't deny that I have some sort of aphrodisiac effect towards the female gender.' He mentally held his chin in thought, 'But it really doesn't make any sense since the medical examination doesn't show that I am capable of releasing any aphrodisiac inducing scent or fluid. All they can really conclude was that my chosen partners could very easily get into heat whenever in contact with me.'

"Adam?" He snapped out of his musings when his brunette partner called out to him.

Adam looked at her as she pleaded, "I can't stand to feel this way anymore... I think I'll lose my mind. Please, Adam, help me like you did yesterday...." Her eyes grew misty while her dainty cheeks were blushing. She closed in on him as she whispered in a begging tone, "Please... give me... my reward. I did good today, right? Please, Adam...."

Her eyes fell downwards, right at his stiff and long girthy sword. She subconsciously bit her lips and gulped as her mouth began to salivate.

She didn't know why she was so entranced by that particular part of Adam, but she did know that she desired to reenact what Adam and Zero Two did in the baths. Just the thought of having it inside her.... her thighs squirmed as her crotch grew a wet patch.

"Plea-"

Naomi was about to plead some more, but her lips were sealed by Adam's sudden kiss. Naomi felt like a she finally found an oasis in the middle of a dessert. She hungrily devoured his mouth in response, immediately throwing out all of her inhibitions through the window once they finally decided to get into the action.

Naomi cupped his cheeks and traced over his slick jaw-lines as their tongues engaged in a heated passion. Before she realized it, she was seated on top of Adam's thighs with his hands grabbing her perky rear in place. Their soppy, wet kiss and the way his large hands grasped her butt made her shiver in excitement. Her waist buckled as she wrapped her legs around Adam's waist, rubbing her core unto his exposed log-like sword.

Their hot exchange elicited several satisfied and yet, yearning moans that was suppressed in between their kisses. Soon enough, Adam began taking off her nightgown, revealing her petite body and fair skin. She wore a cute pink bra that covered her C-cup breasts, which Adam promptly and expertly began taking off without breaking their kiss. His hands then trailed down from her bare back, and all the way towards the waist band of her panties. He tucked his hands inside, fully grasping and pinching her bare ass. Naomi squirmed a little bit, due to the sudden bare contact. But since she already experienced this before, she quickly calmed down and began to immerse herself in Adam's touch.

Naomi's body trembled with anticipation as Adam's hands roamed over her naked frame. The heat of their desire washed over them, causing them to shed all inhibitions and clothing in a frenzy of passion. Naomi straddled Adam, her core grinding against his thick member as she moaned with pleasure. Her arousal was evident as her slick pussy lips spread and molded tightly against his hardened shaft, releasing copious amounts of her sweet nectar.

Feverishly, she began rubbing Adam's large tip against her entrance, the ache within her growing stronger with each tantalizing touch. She knew that only by giving into her deepest urges and taking Adam inside her could she quell the unquenchable fire raging within her. And for Adam, it was entertaining to watch his adorable brunette partner lose herself in pursuit of ecstasy.

'I want it inside me~~' Naomi groaned in her mind. She could feel the tip of Adam's shaft constant teasing over her pussy lips and right at her entrance. She would grind over it, always tilting her crotch a bit forward so that it would slip inside her.

But to her displeasure, it would seem that Adam enjoys teasing her and riling her up since he would always pull back just when the tip could slip inside her. She grumbled inwardly- well, she wanted to, but with how intense and intimate their actions were right now, her brain was slowly turning into mush. She wasn't even entirely conscious of what she was doing and it was all based on her instincts that she would grind her snatch over his member in pursuit of a greater pleasure.

Adam smirked at Naomi's desperate attempts to take him inside her tight heat. He could feel her juices seeping out of her wet slit, coating his tip with her arousal as she ground against him. With a chuckle, he held onto her hips and picked up the pace, grinding against her as well. His length was coated with a mixture of their fluids now, slickening his shaft for easy penetration. Taking advantage of this, Adam thrust forward suddenly, driving his hips into Naomi's opening before she could protest.

"Ahh!" Naomi cried out as her entrance was breached once more. Her eyes widened in surprise at the sudden intrusion, but the pleasure that coursed through her body quickly drowned out any discomfort. The brunette moaned loudly as he began to move in and out of her pussy. His girth stretched and filled her snatch perfectly, causing her to shiver with each thrust. She didn't even notice Zero Two was now sitting up on the bed beside them, watching their intimate encounter with a perverted grin that made Adam chuckle to himself.

Zero Two leaned in close to Naomi's ear and whispered seductively, "It's okay. Release all your desires to him."

Naomi moaned again and reached between them, grasping Adam's side with one hand while the other cupped herself over her breast, pinching her pink nipple softly as she rode him faster. Her squishy rear slapped against his thighs in perfect rhythm with each downward motion of his hips. Every time he thrust into her depths, she cried out his name, begging for more as she became lost in the intense pleasure.

Soon, Naomi's moans grew louder and more frequent as Adam's thrusts became faster and harder. She could feel her orgasm building within her, the heat in her core spreading throughout her entire body. The feeling of his thick length filling her, stretching her, was almost too much to bear. But at the same time, she never wanted it to end.

Zero Two watched with a wicked grin on her face as Naomi completely succumbed to her desires as she bounced on Adam's thighs. Strangely enough, she didn't feel jealous, as one would expect when they saw their beloved with someone else. Quite the contrary, Zero Two even began to feel even more excited as another woman lost her mind while going through the 'procedure' or 'forbidden acts' with Adam. Well, what mainly contributed to her acceptance was Naomi's scent and flavour.

The pure innocence and curiousity buried underneath her quiet exterior, Naomi was similar to a children's book and Zero Two was a devious woman who was going to ruin it with her perverseness.

Oh, the excitement, the immorality... it just makes her shiver in anticipation.

Moreover, Naomi was the perfect audience for her recently awakened exhibition kink. Zero Two saw how the brunette watched them with yearning, curiousity, and desire while she and her darling indulged in their love making during the showers earlier today.

"AHN~~"

Zero Two was brought out of her musings as Naomi's moans began to grow louder, enough for it to be mistaken for a scream. Watching her darling and Naomi, Zero Two couldn't help but feel a bit envious of their connection, but also excited by the thought of joining in on their intimate session.

"Naomi," Zero Two purred, reaching out to stroke the brunette's back. "You look like you're enjoying yourself." she teased.

Naomi turned her head towards Zero Two and smiled blissfully. "I can't help it...Adam just feels so good inside me." Her eyes delirious while her face was feverishly red.

Zero Two chuckled and leaned in close to Naomi's ear once again. "Don't hold back your desires any longer," she whispered seductively. "Let yourself go completely with him."

With Zero Two's encouragement ringing in her mind, Naomi let out a loud moan as Adam hit a particularly sensitive spot inside of her. She could feel herself getting closer and closer to the edge, and she couldn't wait for Adam to push her over it.

Sensing Naomi's impending release, Adam wrapped one arm around her waist and grabbed onto one of Zero Two's hands with his free hand. With their intertwined fingers resting on Naomi's hip, Adam began to thrust even harder and faster into her, pushing her deeper into her accumulating climax, his own body responding to her intense moans of pleasure.

"KYAAHNN!!~"

Naomi released a pitch that she never knew she could reach due to her normally quiet and self-kept personality. Her scream echoed through the room, filling the air with her ecstatic cries as her body convulsed in the throes of pleasure. Her mind was overwhelmed with the sensation, her consciousness slipping away as her pussy walls clenched and unclenched around Adam's girth. Even in her unconscious state, her hips still twitched and bucked, unable to resist the intense pleasure that coursed through her.

Moments later, she collapsed on Adam's chest, her normally quiet and self-kept personality momentarily forgotten in the depths of pleasure. He smiled, caressing her cheeks as he savored the sight of her uninhibited release. He held her close for a few moments, relishing the feeling of her tight pussy walls contracting around him, before finally pulling out and settling her on the bed.

As he did, a pair of arms wrapped around his neck. Zero Two's sultry voice purred in his ear, sending shivers down his spine as his dick twitched in anticipation. "It's my turn again," she sang, her seductive tone a huge turn-on.

"Indeed, my love," Adam replied, matching her sultry tone as he turned to face Zero Two. His sister, however, had other plans as she made her way towards his thighs, her eyes fixed on his still erect member.

With a deep inhale, Zero Two savored the intoxicating scent of their combined love juices, mixed with the sweet aroma of the newly deflowered brunette. The heady fragrance was an aphrodisiac that sent waves of pleasure coursing through her veins, making her feel lightheaded and euphoric.

Unable to resist the temptation any longer, Zero Two opened her mouth wide and slowly began to lick Adam's member, starting from the base of his balls and working her way up to the tip. Her tongue expertly teased and caressed every inch of his shaft, causing him to shudder with pleasure. Adam's hands instinctively reached out to grab her head, guiding her movements as she continued to pleasure him with her mouth.

'It's so tasty!!!' she exclaimed excitedly in her mind as she began to suck Adam's member like it was a popsicle. 'Our flavours are all mixing altogether... it's SO GOOD! It's better than honey- it's better than anything else!'

'Except for darling's juices of course.' she added in the end.

'But still!-' Growing more and more immersed in her work, Zero Two bobbed her head up and down, taking more of his length deep inside her throat without showing signs of gagging.

Soon, she heard silent groans coming from her darling. Cupping his balls, she could feel them start to tighten while his entire member was beginning to swell even larger, signifying that he would soon cum. Zero Two began to work with more enthusiasm, strengthening her suction, coiling her tongue around his head, and massaging his balls.

"S-sister...!" Adam subconsciously began grabbing unto her head. His fingers grasping her hair.

Zero Two smirked, her eyes narrowing in delight. It was only in times of overwhelming pleasure that her darling calls her like he used to back when they were younger. She intensified her work even more and soon, Adam released a guttural groan as he pushed her head downwards, ejected his essence deep inside her throat, to which Zero Two swallowed every single bit of it. She felt his member contract inside her throat as his warm liquid fell directly into her stomach, making her feel full.

As Adam's breathing began to return to normal, Zero Two removed her mouth from his member, feeling satisfied and content. She gently brushed her hair back and looked up at him, a small smile on her face.

"You remember our deal, right?" she asked teasingly, her voice still husky from the oral sex she had just given him.

Adam looked down at her, his eyes heavy with lust. "Of course, my love," he replied, his voice rough. "Everything I do to her, I'll give it to you twice over."

Zero Two arched her back and parted her legs in an M-shape, exposing her glistening pussy that was more than ready for Adam's penetration. She gave him a sultry look and used her fingers to spread her pussy open, inviting him in. "Come on, darling, I'm ready," she purred.

Adam grinned hungrily and promised, "I won't let you sleep tonight."

Zero Two scoffed and playfully rolled her eyes, teasing, "When have you ever?"

"Oh, really?" He lined up his large dick with her spread pussy and, without warning, thrust forward, sheathing himself deep inside her. Zero Two let out a moan as her nether region felt incredibly full - very full. "Cheeky now, are we?" he asked, his voice rough with desire.

Without waiting for another second, He began thrusting earnestly inside of her and once again, it was sleepless night of passion.
