Sealing the Deal
"Mmph?!"
Sherpa's eyes widened as our lips met once again.
Her body stiffened, her movements clumsy, unable to even breathe properly.
The way she just stared with wide eyes, trembling because she didn't know what to do or how to act, paradoxically fueled my desire for conquest.
So, I lightly bit her upper lip to create a gap and slid my hot tongue inside like a snake.
"—!! Mmph, mmph!"
Slick saliva mixed, and hot breaths intertwined.
I firmly supported the back of Sherpa's neck and pressed her down onto the bed with my full weight.
Only after pinning her down so she couldn't budge and relentlessly entangling my tongue to ravage every corner of her mouth did I slowly pull my lips away.
"Haa... haa... Com... Commander? Th-This is..."
Her lips glistening with saliva, Sherpa gasped for air and looked up at me with hazy eyes.
"It's called a kiss."
"A-A kiss?"
"Yes. It's the most basic form of physical affection shared between people who cherish and like each other."
"P-People who cherish and like each other..."
At my explanation, Sherpa swallowed hard and asked with a look mixed with anticipation and anxiety.
"Th-Then! Do you... with the other ECHOs too...?"
"Of course. It's a common form of affection in our Ark."
It was a lie, but not entirely wrong.
"Ah—!"
Sherpa looked visibly relieved at the words that this was a natural thing experienced with other ECHOs as well.
Chuckling at her naive reaction, I naturally yet boldly slid my hand under her rolled-up T-shirt.
It had been less than a year since I fell into this world, but groping an ECHO's body had now become completely natural to me.
Her fair breasts, revealed without hesitation, felt heavy and soft in my palm.
"...Com-Commander, you are a strange person."
"Why?"
"Us-Usually... humans loathe touching an ECHO's body, saying it's dirty."
"Hmm, I've heard that. But I'm not an ordinary human."
I whispered softly while kneading the breast that filled my hand.
"Especially when it's this soft and warm."
"...Ah, nngh! Th-Then, are the other humans in Ark 69 si-similar to you, Commander?"
"No. All the humans in our Ark are dead; I'm the only one left."
"Ah... ahh!"
As I pressed and rubbed her erect nipple with my thumb before taking it into my mouth and rolling it with my tongue, Sherpa's body began to quiver as if struck by electricity.
"Ah, aaah... Com-Commander. I-It feels... strange..."
"What does it feel like? Tell me honestly."
"It's... ticklish... nngh... warm... and my lower belly tingles... I-I feel like my mind is going blank."
"That sensation is called pleasure. It's proof that your body likes my touch."
I leaned down and took her erect nipple into my mouth once more.
"Haaaang!"
As I rolled the nipple with the tip of my tongue and sucked it firmly with my lips, Sherpa's back arched like a bow.
Then, she reflexively grabbed my hair, not knowing what to do with herself.
Her entire body thrashed at the intense sexual sensation she was feeling for the first time in her life.
Slurp, chupa, chup.
“Your reaction is quite good, isn't it?”
"Ah, aaah... Com-Commander! My... my chest feels strange... I feel like I'm melting..."
"It's okay. It just means I like you and find you lovely."
"Aaaah—!"
I naturally stripped Sherpa's clothes off, leaving her naked.
Then, while greedily kneading her other breast, I whispered suggestively into her flushed ear.
"How is it? This is your first time feeling this way, right?"
"Yes, yes... hngh... I-I only learned how to carry luggage... a-and because I'm stupid, I couldn't even properly understand the concept of human love properly..."
"That's not your fault. The humans who couldn't recognize your cuteness are the fools."
I stroked Sherpa's cheek as if praising her, then grabbed her wrist and led it down below me.
Since I had already undone my belt buckle during the kiss, my angry member, which seemed ready to burst through my underwear, was emitting a scorching heat.
"This is..."
"This is called a cock. It's a human male's greatest weakness and his most honest part."
"Aaaah..."
"Usually, it's limp, but in front of a woman I like, it becomes hard like this."
"A woman you like..."
Sherpa hesitantly gripped my member.
The hot, hard sensation against her palm.
Feeling the vivid throb of the veins, she swallowed dryly and looked at me with moist eyes.
"Then, Com-Commander... do you like me?"
"Of course, Sherpa."
In a situation like this, there was no way I wouldn't like her.
"So, you should make me happy too. You can do that, right?"
"H-How should I do it?"
"Grip my cock gently and stroke it up and down. Just like how I stroke your hair."
"Ye-Yes!"
Sherpa wrapped her hand around my shaft with a cautious touch.
Then, staring intently at my member, she began to move her hand up and down clumsily.
Meanwhile, I groped the inside of Sherpa's thighs and naturally stripped away her remaining lower garment.
"H-How is it, Commander? Does it... feel good?"
"Yes. It feels even better because Sherpa is doing it."
"R-Really?"
At my single word of praise, Sherpa's expression brightened instantly.
The fact that she was being helpful, and that I was happy because of her, seemed to encourage her.
Perhaps that was why?
She moved her hand more passionately and nodded.
"Haa... haa... I want to make the Commander feel even better."
"Yes, you're doing great. But... just using your hand is a bit lacking."
"W-What should I do? If you tell me, I'll do my best."
Is this the difficulty level of this world?
Handling a naive ECHO who was completely fallen for me was far too easy.
I stopped Sherpa's hand and pulled out my fully hardened member, thrusting it right in front of her face.
As the pungent scent of cloying precum and the thick, musky smell of a male wafted over her, Sherpa's nostrils flared.
"Open your mouth."
"What?"
"Just like I sucked your breasts earlier, this time you suck my cock."
Sherpa, who had zero sexual knowledge, blinked.
"...Ah!"
But only for a moment.
As if she understood what I wanted, she nodded and, as if possessed, opened her mouth and obediently stuck out her small, red tongue.
The sight was so lewd and submissive that I naturally thrust my hips into Sherpa's mouth.
"Mmph?! Mmmph!!"
The large glans parted Sherpa's lips, pressed down her tongue, and advanced toward her throat.
"Kuuuph—!"
Sherpa's pupils dilated as if they were about to flip.
She flinched, overwhelmed by the oppressive volume filling her mouth and the foreign sensation piercing her throat.
But I didn't stop; I firmly gripped and held the back of Sherpa's head.
"Don't spit it out. Take it deep."
"Mmmph! Mmph!"
"Good girl. That's it, good girl."
At my praise, Sherpa, who had swallowed a few tears, gave a small smile with her eyes.
While doing so, she struggled to open her throat to accept me.
I let go of the back of her head and instead gripped the brown hair tied on both sides of her head tightly with both hands, like motorcycle handlebars.
To be honest, I had wanted to do this every time I saw them.
"Mmmph! Uguguk!"
In a state where she couldn't even turn her head because her hair was held.
I began to thrust my hips heavily back and forth into Sherpa's mouth, who was helplessly receiving my movements.
Slurp! Squish! Squish!
Chup! Keok!
The saliva filling the narrow mouth tangled with my member, creating a wet and lewd noise.
"Yes, you're doing well, Sherpa. I can see you have a talent for this. Roll your tongue like that and remember my scent."
Though she suffered from the lack of breath, Sherpa desperately worked her tongue to avoid slipping from my grip.
"I'm cumming. Drink every single drop."
"Mmmph!!"
The sensation of ejaculation reached its limit.

I pulled Sherpa's hair even more roughly and slammed the glans into the deepest part of her throat.
"M-Mmph! Ugh! Gulp...! Gulp, gulp."
Though she writhed in distress, Sherpa moved her Adam's apple according to my command and swallowed everything I gave her without leaving a trace.
"Whew..."
After squeezing out the last drop, I slowly pulled my hips back.
Looking up at me with unfocused eyes, saliva and white foam dripping from her lips, Sherpa was already covered in marks proving she belonged to me.
"Well done, Sherpa. Absolutely wonderful."
I stroked her sweat-soaked hair and gave her a tender smile.
Like an ECHO starved for praise, Sherpa rubbed her cheek against my hand and smiled even with her dazed eyes.
"Now that the appetizer is over, I should show you the real thing."
"...The real thing?"
"Yes. How to become a woman."
I pulled the limp Sherpa up on the bed and forced her pale white legs wide open with my hands.
Having no sexual knowledge, she simply followed my lead like a gentle lamb, exposing her most private area defenselessly.
"Hngh, Com-Commander... there..."
"It's okay. It'll feel much better than before."
"Ah..."
I aligned the tip of the glans with the soaking wet entrance and thrust my hips in one go.
"Ugh—?!"
At the first sensation of something entering her, Sherpa's body arched like a bow once again.
The narrow, hot inner walls, which had never accepted anything, tightened around my member as if to snap it.
"Com-Commander... ngh! Nnnngh—! Ahh!"
"How does it feel?"
"I-I don't know. Ah, aaah...! I can... feel the Commander. Inside me...! Haat! Nngh—!"
"You can feel me?"
"Yes, yes—! The Commander's cock...! Ah—! Inside me...! I-I like it! I like it so much!"
A desperate moan consumed by pleasure.
I gripped Sherpa's pelvis tightly and continued the heavy piston movements.
"B-But it's strange! I... I feel like I'm going to break!"
But that was only for a moment.
As my member began to thud against the entrance of her cervix, Sherpa's eyes began to roll back.
"Ah! Aang! Aaaaah—! Commander! Commandaaaaan!!"
Following a scream that was almost a shriek, I poured my hot semen without reserve into the deepest part of Sherpa.
◇◇◇◆◇◇◇
"Whew..."
As I stepped out of the quarters, the cold dawn air cooled my heated body.
As I adjusted my clothes feeling satisfied, a familiar silhouette leaning in the darkness chuckled and spoke to me.
"Did you enjoy yourself, Commander?"
"...Pomen. You're not asleep yet?"
"ECHOs don't really need much sleep. Sleeping is... just like eating for us."
Pomen then gestured with her chin toward Sherpa's room.
"So, how was it? The ECHO from the other Ark?"
"Seems like there's a lot to teach her. Well... she wasn't as good as you, Pomen."
Pomen chuckled at my sly answer.
The first experience and clumsy reactions did stimulate a man's desire for conquest.
But in terms of the depth of pleasure, ECHOs like Pomen or Helena, who had grasped my tastes and had already become accustomed to them, were far more stimulating.
"I bet she's completely fallen for our Commander now."
It was exactly as Pomen said.
The twin-tailed ECHO who had been whimpering and clinging to me under me all night had practically revered me as a savior just before the final ejaculation.
Both her body and mind had been completely conquered.
"So, what are you going to do about the other one?"
"Compass... I'll have to think about her for a bit."
Unlike Sherpa, she still hadn't let down her guard regarding our Ark.
The type with a strong sense of responsibility and high defense mechanisms.
If I approached her rashly, it was more likely to have the opposite effect.
"By the way, she's strictly an ECHO belonging to another Ark. What do you plan to do? You can't just keep her in our Ark blindly, can you?"
"Hmm..."
That was a bit of a concern.
Since I had already gathered information about Ark 86 and the surrounding situation through Sherpa, it felt like a waste to just send her back.
"First, I'll have to make a deal."
The best scenario would be to get the entire Pathfinder squad in my hands.
But if not, I intended to at least take Sherpa.
Well, I could slowly bring the other members later. Since I was the one who seduced her, I intended to take responsibility.
"As expected of the Commander! This is why I like you!"
"I think you would have liked me even if I had made the opposite choice."
"That's also true."
Anyway, to do that, I had to make contact with the forces of Ark 86, whenever they might arrive.
◇◇◇◆◇◇◇
At the same time.
Two shadows were running desperately through the darkness.
They were Zero, the sniper, and Bait, the assault specialist of the Pathfinder squad.
Having left to request support from Ark 86 under Compass's orders, they had captured ally communications marred with static noises since this afternoon and were hurrying back.
"Haa, haa... Bait! Look over there—!"
Where Zero pointed, several searchlights were tearing through the darkness, approaching them.
Upon discovering the heavily armored vehicles, the two ECHOs waved their hands in relief and ran forward.
Screeech—!
The command armored vehicle at the front stopped in front of them, kicking up dust.
Gasping for air, the two took their positions and gave a disciplined salute toward the vehicle.
"Salute! Pathfinder squad..."
Pshhhhh!
With the sound of hydraulic pressure releasing, the upper hatch of the armored vehicle opened.
Bait looked up, expecting the cold but competent fleet commander, Lin Xiaolin, to appear.
However...
"Eh—?"
The man who emerged from the hatch was not the person they expected.
Irritable eyes, an arrogantly twisted corner of the mouth.
And a contemptuous gaze that looked at ECHOs as if they were filth.
"What's this? Why are there only two pieces of scrap metal?"
It was Lin Ao, one of the notorious commanders of Ark 86.
And instead of accepting Bait's salute, he spat phlegm on the ground.
His irritated voice rang out coldly.
"Aren't you going to report properly? What's with that look?"
"I-I'm sorry! There was an engagement on the way..."
"Shut up. Don't give me pathetic excuses."
Lin Ao waved his hand as if shooing away a bug.
"And you, are you blocking the front of my vehicle right now?"
"What? N-No, I'm not!"
"Move, you're an eyesore."
Lin Ao flicked his finger dismissively.
At that trivial signal, the massive turret of the armored vehicle stopped in front of Bait and rotated with a whirring sound.
"Uh...?"
It was the moment Bait tried to step back in panic.
Thwack—!
With a dull bursting sound, Bait's body flew into the air.
The steel barrel of the armored vehicle had struck Bait's side like an iron club.
Seeing this, the adjutant beside him exclaimed in shock.
"P-Platoon Leader?!"
"What?"
"F-Fleet Commander Lin Xiaolin said not to exercise violence against ECHOs..."
"So what? Is Fleet Commander Xiaolin here right now? She's not, is she?"
Looking at the ECHO thrown into the darkness, unable to even scream properly, Lin Ao smirked as if it were amusing.
