Awakening Instincts
"C-Commander... and the Leader... are, uh, doing that?"
"Yes. The Commander is a man. It's a natural physiological phenomenon for a man to feel lust for a woman."
"But...!"
Luna shouted abruptly at Silva's calm response.
"The Leader is an ECHO! And the Commander is a human?!"
Her cat ears stood straight up, trembling violently.
Physical intimacy between a human and an ECHO, who was created as a combat weapon?
It made no sense to begin with.
Humans were the kind of creatures who would spend the entire day disinfecting their hands just because of brushing their fingertips with an ECHO.
It was a sight she had seen very commonly in Ark 74, where they had been.
O-Of course! The Commander of our Ark treats the ECHOs with friendliness, like family, but...
Still, there was a line that could not be crossed.
From the moment she was created till now, Luna had never once heard a story of such sticky physical intimacy occurring between a human and an ECHO.
Then, Silva tilted her head and dropped a bombshell as if it were nothing.
"I've done it too."
"Wh-What?"
What?
Luna's thoughts came to a grinding halt for a moment.
"The Commander kissed me, and he touched my breasts. And he put his huge phallus inside here, too."
With a dry expression, Silva slowly stroked the area below her navel.
The touch was strangely erotic, causing Luna to unconsciously gulp and open her mouth.
"Wh-Whaat? Wh-When?!"
Luna's eyes grew wide enough to fall out.
Her face was flushed bright red to the tips of her ears, looking as if steam would erupt from the top of her head at any moment.
"Hehehe."
Finding Luna's reaction amusing, Silva let out a chuckle for the first time.
Was it a joke? Or is it real?
As Silva’s usually icy expression melted slightly, Luna became even more confused and tilted her head.
"Are you curious?"
"I-I mean... of course!"
There was no way she wasn't curious.
An ECHO receiving the love of a human?!
That was a plot that didn't even appear in novels.
"Then, shall we go take a look?"
"L-Look at what?"
To the gulping Luna, Silva whispered softly, gesturing with her eyes toward the warehouse visible in the distance.
"Our Leader, being fucked by the Commander."
"……."
"Don't you want to see?"
Luna's mouth hung open.
It was a devil's proposal—one she knew she shouldn't accept, yet found impossible to refuse.
"...I-I want to go."
And so, with a face flushed red and her tail puffed up, Luna began to trot along behind Silva.
◇◇◇◆◇◇◇
"U-Uh..."
"Shh."
Sneak, sneak…
A sniper and a cat.
The two of them, keeping their voices down, headed toward the old warehouse building where the Commander and Helena had disappeared.
Creak...
True to her role as a sniper, Silva discreetly found a vantage point and created a gap in the decayed iron door.
Guided to that gap, Luna held her trembling breath and peeked inside.
"—!"
The moment she looked through the narrow gap Silva had made, Luna felt a massive shock, as if her entire world were collapsing.
"U-Uh..."
Silva's words, which she had half-doubted, were unfolding right before her eyes.
No, it was more than that.
Plap! Plap! Plap—!
The wet, violent sound of flesh hitting flesh.
And Helena's moans, which were unimaginable under normal circumstances, pierced Luna's ears in their rawest form.
"Hngh! Ah! Ngh! C-Commander...! My pussy... my puss….yyyy!!"
"Tighten it more!"
Every time the Commander's elongated cock slammed down from above into Helena, her entire body convulsed violently.
Her slender waist arched like a wave, and her voluptuous breasts bounced deliciously.
"G-Gulp..."
Is that the act of mating called sex that she'd only heard about?
Helena, being impaled by the Commander's genitals, was not the cool-headed leader Luna knew.
She was nothing more than a fucking bitch drenched in pleasure, driven mad by a male's cock.
The sight of her screaming her lungs out while shaking her hips from side to side was so erotic and shocking that Luna felt dizzy.
"Gulp..."
But Luna could not tear her eyes away from the scene.
She was scared and embarrassed, but an intense curiosity beyond that dominated her entire body.
"Haaah! Ngh! Ah, aaah—! C-Commander...! More, more—!"
What captured Luna's attention most of all was Helena's face, melting in pleasure.
Even though she was handled so roughly by the Commander, bliss shone intensely on her features.
It was an ecstatic expression, as if she possessed everything in the world.
What does it feel like?
The feeling of being loved by a human, and by the beloved Commander?
It was the first time she had seen the Leader's face look so happy.
Just then, Silva whispered dryly beside her.
"That position is called doggy style. Given an ECHO's physical structure, it's the position that can stimulate the cervix most deeply and accurately."
"C-Cervix...?!"
"Yes. The Commander likes doggystyle the most; he often takes ECHOs in that position."
Luna unconsciously gulped and fixed her gaze on the gap again.
Every time the Commander's firm thighs moved, she could clearly see the large artifact sliding wetly in and out between Helena's buttocks.
"……."
At that explicit sight, Luna felt a tingling sensation between her legs, and a thump echoed deep in her lower abdomen.
A jolting sensation, like an electric current, surged up her tailbone.
"Ah, he's about to ejaculate."
Just as Silva said, the movement of the Commander's hips began to turn rougher and faster.
Plap! Plap! Plap! Plap!
The violent sound of friction, as if flesh were about to burst, filled the warehouse.
"I'm cummming, Helena—!"
"Y-Yes! Inside! The Commander's grace—!! Ah!"
Helena threw her head back and let out a scream of rapture.
"Oooooh!!"
As the Commander, who had been moving his hips rapidly, drove himself in one last time—deep, very deep—a moan like a beast's cry of joy erupted from Helena's mouth.
Then, the Commander's hips slid all the way out.
"Ahh... haah! Heuuugh……."
Helena’s pupils were unfocused and hazy.
In those depths, instead of the light of reason, only an obscene mark signaling her complete submission to the male bloomed clearly.
Then, from between Helena’s swollen pussy, whose body was still twitching with pleasure, a thick white liquid flowed out.
"That is..."
"The Commander's semen. The essence of a human, containing the energy of life."
"……."
The moment she saw it, Luna was overcome by an intense urge to lick that white liquid.
She wanted to taste that thick substance with the tip of her tongue and hold it full in her mouth.
What would it taste like?
What would it feel like?
And how did Helena feel right now, having received the Commander's hot seeds to fill her womb?
I... I want it too.
Luna unconsciously gulped.
She felt as if her throat were drying up, burning.
"Let's go now."
Seeing the Commander start to stand up, Silva grabbed Luna by the scruff of her neck and pulled her away.
"Any more than this is dangerous, Luna. We might get scolded if we're caught."
"Ah..."
At Silva's words, Luna licked her lips regretfully and was hurriedly led away by Silva.
However, her mind was filled with the shocking and erotic scene she had just witnessed.
And in a corner of her heart, envy toward Helena and an unknown sexual curiosity were blooming hotly.
◇◇◇◆◇◇◇
"Whew..."
I let out a deep breath and looked up at the ceiling.
As the heat of pleasure that had spread through my entire body slowly subsided, a languid sense of satisfaction filled the void.
Is this... the legendary post-nut clarity?
Anyway, I managed to get a satisfying release in the middle of the mission.
"Commander."
Helena, lifting her head from between my legs, looked up at me with a flushed face.
Traces of the desire I had poured out a moment ago had smeared her lips white, and her voluptuous breasts, visible through her disheveled garter-belt combat uniform, heaved heavily with every breath.
"Ah..."
The bitch who had been moaning like an animal under me until a moment ago was gone, and her eyes looked as if she were returning to be the loyal leader of Cerberus.
Of course, the heat lingering in those eyes had not yet vanished.
"Clean me up one more time."
"Understood, Commander."
At my words, Helena once again skillfully used her tongue to gently lick away the remnants of cum on my cock.
"Good job, Helena. You were wonderful."
"Thank you, Commander."
Helena was a woman who looked like a high-powered career woman you wouldn't even dare speak to in society, and in this other world, she was an Original ECHO and a squad leader who dominated the battlefield with her trusty shotgun.
Such a woman was not only pledging her loyalty to me but was actively playing the role of a bitch in heat.
This gap moe is truly the greatest privilege a Commander can enjoy.
Not just Helena, but countless ECHOs were waiting for my touch, their Commander and a human.
It was while I was putting on my clothes and tidying up my appearance.
"By the way, Commander."
Helena, pulling up her panties, spoke cautiously.
"Hmm? What is it?"
"A moment ago, Silva and Luna came by and watched us."
"……Eh?"
I froze while adjusting my clothes.
"I-I mean. They came by? When?"
"Around the time the Commander was bestowing plenty of divine grace inside me."
"……."
My thoughts stopped for a moment.
Divine grace?
No, more importantly, just now?
Does that mean they saw that entire violent doggystyle session?
"They came sneaking in like cats and peeked through the gap in the door before leaving."
"……."
Helena spoke as if it were nothing, but I felt like digging a hole and hiding inside. That was how shameful the news was to me.
I mean, I can accept Silva, but why Luna?
More than that, thinking that I had been seen grabbing Helena's hips and pounding into her like a beast, a sudden wave of intense embarrassment and mortification washed over me.
I've become quite shameless in this world, but I wasn't at the point of openly enjoying outdoor sex play.
Moreover, Luna was an ECHO I hadn't even had simple skinship with, other than patting her head.
"A-hem... I see."
I tried to act natural, clearing my throat and changing the subject.
By the way, there was one word that had been bothering me.
"But Helena. That word, divine grace that you mentioned. Where did you learn that?"
"Ah! Noah told me."
"……."
"She said that mixing bodies with the Commander and receiving the Commander's seeds is the greatest honor an ECHO can enjoy. Therefore, it is called receiving divine grace."
Noah... just what on earth are you telling people?
Are you trying to start a religion centered around me?
But seeing Helena speak with a look of absolute certainty, I couldn't bring myself to throw cold water on her.
"Right... well, as long as you used it in a good sense, it's fine."
So, I just chuckled awkwardly and did my best to brush off the subject.
Then, Helena asked me cautiously once more.
"But Commander."
"Yeah?"
"By any chance... is Luna lacking in some way because she is a beast-type ECHO?"
"??????"
Lacking? In what?
