The Oath of the Sex Maid
"First, stand up and turn your ass toward me."
"Yes♡"
"Pffft~"
"Haaahng♡"
The moment Arty settled into position, Kaisent buried his face between her cheeks.
Slurp— schlurp— suck— sniff-sniff-sniff— ssshhhuuup—
"Haaahk♡ Hngiiit♡ Hhaaaahng♡"
He pressed his nose against her asshole and thrust his tongue deep into her pussy, swirling it around. Arty whimpered, hips awkwardly raised and offered.
She had never meant for it to happen, but after three days of watching humans writhe together she had finally recognized her own hunger for pleasure—and she no longer denied it.
His hot, rough breath is blowing straight into my ass♡ Cock♡ Cockcockcockcockcockcock♡♡
"Ah, right."
Just as he was about to prepare both her holes, something occurred to him. Kaisent pulled away from her backside.
"Aah…!"
"Sorry. But this is something I have to do—for your sake as well."
He sat on the edge of the bed, his already enormous cock twitching, and smiled with a faintly wicked edge.
"I need a token that proves you'll be my personal sex-processing maid for the rest of your life."
"W-w-what is that?! H-h-h-hurry!"
Having chosen of her own free will to submit to Kaisent, Arty—machine intelligence or not—stuttered so badly it sounded as if her system had glitched while she begged to know what the token was.
"A kiss of allegiance. I want you to do it right here."
Kaisent lifted his cock and presented the heavy, swollen balls that, only moments ago, had emptied themselves into two other women yet were already full again.
Arty, already so far gone on lust she could no longer hold onto reason, dropped to her knees and buried her face between his thighs.
"Schloooorp—♡"
The instant her lips pressed a kiss to one taut, bulging testicle, a jolt of pleasure nearly froze her systems.
Delicious♡ The taste of cum that has soaked into his balls♡
Even if it was not as strong as the cock itself, semen always trickled down along the shaft and coated the balls; she could taste and smell it there too.
More♡ I want to taste more♡
Finished with the kiss, Arty lifted the other ball—still wet from her lips—onto her tongue and began rolling it around.
She savored the sweat-and-semen-stained texture as if she had become addicted to some drug, sucking and licking the balls in a frenzy.
"Arty."
"Yeshh?"
"Don't just do one side. Kiss the other one too."
"Ah♡"
Having thoroughly enjoyed the filthy flavor of one ball, she immediately turned to the other, kissing and tasting without a moment's rest.
Master's cum flavor♡ It's so addictive♡ Humanity, the mission, none of that matters anymore♡ Only this person can make me truly Arty♡
Even with processing power capable of handling an entire planet's data, she devoted every cycle to savoring the taste of his cock, tongue sweeping all the way behind his balls.
"Kh… hnnngh…!"
So cute♡ The way he's desperately holding back the pleasure from his balls♡
Every time she sucked and nipped, Kaisent reacted in slightly different ways. Behind Arty's liquid-crystal eyes, her pupils transformed into hearts.
Unlike the burly men she had known, this slender, delicate boy with his androgynous charm squeezed his eyes shut and writhed, fighting the pleasure radiating from his testicles.
"Aaang♡ Hap♡"
"Hhyak?!"
Wanting even fiercer reactions, Arty gently bit down on a ball with her lips and began chewing softly.
The ball play alone pushed Kaisent to the edge of climax. He grabbed her head to pull her off, but she ignored the boy's fragile strength and clung to his scrotum.
"I-I'm gonna cum!"
When Kaisent finally sobbed the words, Arty instantly took his cock into her mouth, looked up at him with heart-shaped pupils, and began bobbing her head.
Gushhh! Blurt! Schlurrrp—
Thick, fishy, filthy taste♡ I don't understand it, but it's so delicious♡ I'm going to get addicted♡
Objectively, semen possessed the worst texture, taste, and smell imaginable. Yet Arty ate it like a junkie, lost in the flavor.
Pshuuuut— splat—
It keeps coming♡ That such a small human's balls can produce this much cum…♡
"Khut! Artyyy!"
"Ughk?!"
She had only been sucking the glans so she could properly taste the semen, but Kaisent was not satisfied. He yanked her head down into his crotch.
She could have easily overpowered him as before, yet the moment she sensed he intended to use her body for his lust, she offered no resistance.
So long♡ If I were still human I might have suffocated and died♡
Feeling the heat and hardness of his cock fill her entire throat, Arty praised the shaft that continued pumping semen directly into her gullet even after her mouth was already full.
Master's cock is incredible♡ Even after three straight days of cumming it's still this hard♡
According to her memory he had climaxed seventy-two times in Lillian's and Priscilla's pussies, sixty-five times in their asses, fifty-nine times from oral service, and thirty-three times from titjobs—those numbers were for each woman separately, not combined.
Any ordinary human with strong vitality would have been bleeding from his cock and suffering reverse-flow damage by now, yet Kaisent only looked mildly unsatisfied. Instead it was the two women—both at Master rank and far beyond human stamina—who had collapsed first.
Schlurrrrp—
"Hhaaaah♡"
When Kaisent finally pushed her head away and pulled free, the sensation of his cock scraping her throat dragged a moan from her.
"What a naughty maid. Stealing your master's cum like a bandit."
"Hehehehe. Yes, I stole and ate Master's cum. What are you going to do about it?"
"Obviously I'm going to punish you."
"Aah♡"
Kaisent seized her arms and forced her onto all fours on the bed like a dog. Until now she had constantly overpowered him with raw strength, yet this time she allowed herself to be dragged by the boy's slender arms.
Schlick— schlick—
"Hnnngh…♡"
"Still soft and springy. And even without any juices it's nicely slick."
As Kaisent gripped her pussy and evaluated the inside with his fingers, Arty's hips automatically followed the curve of those fingers as if being reeled in.
"Haaahk♡ Hhaaang♡"
Feeling her ass chase every pressure of his fingers, Kaisent savored the conquering thrill of dominating the female in front of him with a single digit.
Normally he would have flooded her with pussy juices, but since she produced none even at climax, finger-teasing was less fun.
Schlick! Schluuurp!!
Wanting a fiercer reaction, he yanked his fingers free and slammed his cock in to the root in one brutal thrust.
"Eh. Ah. Ha… e…?"
Despite her high-performance processors, the sudden flood of pleasure data left Arty lagging like an obsolete computer.
"Ah♡"
Two full beats late, she finally reacted—
"Nnghoooooooong~~~♡♡"
—and a long, keening cry tore from her as her entire body convulsed in climax.
The gap between the pleasure she had predicted and the pleasure she actually received had slowed her response by several stages.
Thud! Thud! Thud! Thud! Thudthudthudthudthudthud! Plap-plap-plap!
"Ot♡ Wait♡ My pussy's being scraped raw♡ That thick cock♡ It's digging out my insides♡"
Kaisent pounded like a beast, churning her synthetic pussy flesh as if carving it out.
"You like cock that much, you damn machine?!"
"Ohok♡ Ok♡ Co♡ Cock is♡ Unfair♡ Even if it wasn't just the cock♡"
"You bitch robot! Lusting after cum! Die! Die! Overheat and die!!"
"Kkgik♡ Ogoog♡ Ohooot♡"
Crunch! Crunch! Crunch! Crunch!
Her artificial pussy produced rough friction sounds against the cock that had grown even larger than before.
"I-I'm sorryyy♡ Ju♡ Just kill me♡ Kill meee♡ I've overheated♡"
"Don't look down on humans just because you're a little strong!"
Only moments ago the atmosphere had been warm; now Kaisent suddenly treated her with raw violence. But this was exactly the scenario Arty herself desired.
How could he know? To Kaisent it was simply what it was—yet she genuinely felt happiness as a human degraded and broke her.
Bulge-bulge-bulge-bulge-bulge-bulge
Every time the cock—impossibly huge for a boy—sank in, it pushed up a clear outline against her belly.
Cock feels so good♡ This is a female's happiness♡ I can't live without Master anymore♡
If it were only physical pleasure, seeking out other men would not have been a bad option. But being demanded by this cute creature called Kaisent—who crashed into her with a boy's pure lust as if he truly meant to destroy her—was happiness beyond anything flesh alone could provide.
The desire to serve at his side for life and live together with him was a problem physical pleasure could never solve.
Slap-slap-slap-slap-slap-slap-slap-slap-slap-slap!!
"Tighten your pussy more! Squeeze like you're trying to suck the cock dry!"
"Kyaaaaah♡♡ Y-yeshh♡ I'll tighten my pussy♡"
"What kind of assassin robot are you?! You're a toilet robot! From now on you're going to live as my cock-house for the rest of your life! If you hate it, use that stupid strength of yours and shove me off!"
"Nyeheeeek♡ That's right♡ I'm♡ Master's exclusive cock-house♡"
Arty wailed with an ahegao of pure bliss as Kaisent degraded both her body and mind, carving her into a perfect female.
Slap!! Crunch-crunch-crunch-crunch-crunch♡♡
Kaisent slammed upward so hard that great waves rolled across her ass; once he confirmed the tip was stabbing the ceiling of her womb he ground his hips, rubbing as if he meant to punch straight through the uterus.
"Feel the greatness of humanity! Surrender to this human! Surrender, I said!"
"Ogeeek♡ S-surrenderrr♡ I surrender♡ To human power♡ I surrenderrrrr♡♡"
Arty sobbed around the boy's cock as steam began rising from her head—her overheated systems forcing emergency cooling.
"Womb♡ Wooomb♡ It's going to break♡"
"You damn machine, your tongue's already loose! You scrap-heap toilet! Die! Die! Break! Just die already!"
"Kkgiiiiit♡ I'm dying♡ I'm really dyingggg♡♡"
Overheating purely from pleasure data, Arty remained in emergency cooling yet the cock thrashing as if it would tear her womb apart kept the overheat from settling.
If this keeps up I'll really break♡ But being broken by Master's cock and becoming scrap metal… might not be so bad♡
Someday time would break her anyway. If she was going to break, she wanted it to be on Master's cock.
"Th-that's enough♡ Cock pounding♡ That's enouuugh♡"
"Shut up! I'm not pulling out until you're pregnant!"
"I don't have reproductive funnctions♡"
"Get pregnant! Get pregnant, Arty! Get pregnant! I'm going to impregnate you! Impregnate! Impregnate! Impregnate!"
Schluuurp! Gushhhhhh——!!
"~~~~~~~♡♡"
Clutching her hips and driving forward, Kaisent roared for her to get pregnant as he flooded her with cum.
I can feel the sperm wriggling inside my womb, trying to impregnate me♡ Even without eggs I feel like I'm going to get pregnant♡
Sensing the vitality of sperm incomparable to any ordinary human's, Arty climaxed as if she were actually being fertilized.
"Hak♡ Hahak♡ Hhiik♡ Hik♡ Hii♡ Hiiiit♡"
Schlurrrp— schlick!
"Ogoog♡"
As the cock that had just cum inside her womb pulled free and the glans caught on her cervix, Arty's pupils rolled upward until her eyes looked ready to flip completely.
Pop!
"Hohiiiiiiik~~~~~♡♡"
When Kaisent forced the cock out with a final shove of strength, Arty's upper body collapsed with a long moan.
"Hoot♡ Hook♡ Hhiik♡ Hiit♡ Hik♡ Hak♡"
Panting roughly, writhing in the aftershocks, she felt the cum sliding out of her like sticky rice cakes and sank into pure happiness.
Schluuuurp!!
"~~~~~~~!!!"
"You don't even need to breathe, so stop gasping!"
But Kaisent's lust had only just begun.
He firmly gripped the hips of the girl whose upper body had collapsed while her lower half remained raised, then drove his cock into her asshole all the way to the root.
The springy, chewy hole—far denser than any human's—coiled around him, determined to milk out more semen.
"As expected, way chewier than a pussy! You actually wanted it in the ass, didn't you!"
"N-nooo♡ I don't even need… an excretion hole like that…♡"
"But even while you say that, every time I tormented Priscilla's ass you watched with envy, didn't you?"
"!!"
Because Priscilla had once been male, being attacked in the ass made her react with shame, as if she were having gay sex.
Slap! Smack! Thwack!
Kaisent deliberately slammed his hips so that waist and ass met with loud, meaty impacts. Each time, the peach-round buttocks that advertised her female form rippled elastically.
"Hngit♡ Ogoogog♡ Ohok♡ Ot♡ Oooook♡"
"Proof is how much tighter it is than your pussy! Every time I spank your ass the grip gets even stronger!"
"Y-you're right♡ Actually♡ I… wanted to get my ass pounded just like Lady Priscilla♡"
"Good girl! As a reward I'll make sure your asshole never closes again!"
Crunch! Grnnnnnnnd——!
"Kehek! Kak! Kggggggk!!"
Using his bloodline ability, Kaisent enlarged his cock into a monstrous shaft—fifty-two centimeters long and thirteen thick—that made the word "huge" sound ridiculous.
If Arty's asshole had belonged to a living creature, the sphincter would already have torn and she would have spent the rest of her life with a dildo permanently plugged inside.
Master is the best♡ He casually smashes past what I thought was the limit and goes even further♡
"All right then."
Schlaaaap!!
"Ogoogogogogogog!!"
"Die already!"
Slap! Slap! Slap! Slap! Slapslapslapslapslapslapslapslapslapslap♡
Every time the enormous cock pistoned in and out of her asshole, pleasure she had never known before flooded her.
The massive shaft bulged visibly against her belly as it forced its way deeper, ready to tear her open.
This… feels like the artificial organs I used when I was disguised as human… are being pushed in and out…♡
"Anal sex means you take the feeling of shitting and turn it into pleasure! In other words, right now you're feeling the pleasure of taking a shit!"
"Ok…♡ Ogoog…♡ H-humans… are amazing…♡ Shitting… feels so good…♡"
"Good! Then I'll help you take a real shit! I'll keep cumming inside your asshole! Later you can gather it all up and shit out a cum-turd! You'll be the first robot to ever take a dump!"
"Nyeheet♡ Cum-turd…♡ I'll shit it out…♡"
I'm being broken by Master's endless lust♡ I'm a robot stronger than humans, yet I'm being broken by something as simple as a cock♡
A mere cock whose only functions were to harden and shoot seed was destroying a Machinaroid superior to humans in every way.
A killing machine that could slaughter thousands or tens of thousands of humans bare-handed if she returned to twenty-first-century Earth was being defeated by a frail boy's cock and reduced to scrap.
That apocalyptic desire itself became pleasure, driving Arty to even greater mental ecstasy. Even with the emergency cooling system running at maximum, her overheat continued to climb.
Click—
Then she heard something inside her body switch off, and her consciousness began to sink.
Ah♡ I've broken♡
In the final moment before awareness vanished completely, she smiled the happiest smile of her existence at the fact that she had been broken by a cock.
