Arty's Cruel Education
This♥ this♥ is the best♥ the absolute best♥
Lilith trembled from head to toe, savoring the aftershocks of an orgasm so fierce it had melted her brain. Her own thick semen coated her body and face in sticky layers; the heavy musk of it filled her nose and only sharpened the lingering waves of pleasure.
Squelch—
“Oooohk!?”
“You weren’t thinking this was over just because you came once, were you?”
Kaisent had no intention of stopping there. She had treated his life as a disposable tool without a second thought; wringing her dry to the absolute limit stirred not the slightest guilt in him.
“W-wait! Stop! Stop it right nooow!”
“Who said you get to decide?”
Click! Bzzzzzzzzzzzz———!!
“Ogohoooooh~~~!!”
The dark elf had just emptied herself so thoroughly her balls had shriveled like a white elf’s; now a vicious vibration slammed straight into those emptied sacs. The impact struck her testicles head-on.
Click!
Just when it seemed the ball-torture device would keep tormenting her, the switch clicked off and the machine fell silent.
“Haah♥ hak♥ haaah…?”
A question mark floated over her head as she tried to understand why the assault on her jewels had suddenly stopped—then someone seized the shoulders of the prone Lilith and hauled her upright.
“You!?”
“I saw something strange going on and came to look… and here you are having all the fun without me, Master.”
Pleasure had completely blinded Lilith to Arty’s approach, but Kaisent had of course sensed her. A silent exchange of glances had been enough for him to kill the switch.
Grab!
“Hiiih!”
Arty yanked Lilith fully upright and reached down, closing her fingers around the dark elf’s balls.
“Unlike Master, your testicles are slick and soft even though you look female on the outside. Quite an interesting texture.”
“Nngh♥ uheek♥ l-let… let go…! You… damn golem… aah…♥”
“I wonder how long you’ll keep that attitude.”
Arty began rolling Lilith’s balls between her fingers exactly the way one might toy with a pair of smooth beads.
“Did you know, Lilith? The very day I swore to serve Master as my Master, you attacked him. On the day I pledged my absolute loyalty, I nearly lost him forever.”
“Ook♥ ooh♥ hik♥ hhaaaaah♥ ohoot♥ ooooh~~~♥”
“Just remembering that day is enough to make me understand what humans call PTSD.”
The shock of almost losing her newly sworn Master still burned hot; Arty’s hostility toward Lilith was raw and open. The gentle caressing fingers suddenly clenched. Index and thumb crushed the right testicle with merciless force.
“Uheeeergh!! Hhuk!”
Pain two full steps past the border of pleasure crashed through her. Forced upright, Lilith’s legs began to shake violently in an awkward half-standing posture.
“Y-you damn… golem…!”
She poured every scrap of remaining strength into a mana-charged knife-hand strike aimed at shattering Arty.
Squeeze—!
“Hhoooooh!!”
Arty simply tightened her grip even harder. Lilith’s body buckled as though she were about to collapse; all power to attack vanished. With her balls held hostage she could not even tense her muscles.
“Heh heh heh. How does it feel? The humiliation of being completely helpless just because someone has your testicles?”
“Kk… kkuuk… kheuk…! L-let… go…! They’re… gonna… burst…!”
Arty’s strength was formidable, yet Lilith was a powerhouse who could at least hold her own if she truly tried. Right now that same powerhouse was frozen solid by nothing more than a grip on her balls. Having effortlessly crushed every attempt at resistance, Arty eased the pressure and resumed the slow, rolling massage.
“Ahn♥ th-this♥ kind of… aah♥ ahhaaah♥”
A golem she could smash to scrap if she put her mind to it was casually fondling her testicles. The shame and humiliation were overwhelming—
Squeeze— ssssslick! Slick! Press— press— press—
“Oooohk♥ don’t♥ knead them like thaaat♥♥”
“You’re getting off from nothing but your balls? In our world intelligent beings like you are called masochists. What do they call them in yours?”
“Sh-shut up♥ I’m♥ not… that kind of… aah♥”
“Is that so?”
Arty simply kept kneading, rolling, squeezing.
“Kkeuhnnngh~♥”
“You’re trying so hard to hold back just because I called you a masochist. But did you know? Normal people don’t ejaculate from ball play alone.”
“Hhigiiik♥ s-stop iit♥”
Arty’s hand began to vibrate at high speed while still clutching the testicles. The dual assault of kneading and vibration arched Lilith’s spine like a drawn bow; her upper body snapped backward.
Pshuuuut— pshk— pshushushush—
“Kkyaaaaah~~♥♥”
Thick ropes of semen shot out with a force that made it hard to believe she had already come once. The shame and humiliation were gone; only pure ejaculatory bliss remained. Tongue lolling, face blissful, she simply rode the high.
“A face perfectly suited to a masochist.”
“A♥ no… I’m… not… that kind of… pervert… aah…♥”
“Denying it with that expression? Very convincing.”
Feels… so good…♥ I never knew something like this…♥
The awakened blood of the Demon King of Lust only grew denser the more intense the pleasure became. As Lilith slumped, Arty prepared to escalate—only for Kaisent to stop her.
“Wait a moment, Arty.”
“Yes.”
Without a single question she halted and took up a position from which she could strike Lilith at any instant.
“Lilith, are you all right?”
“Haah… hah… I-I’m… fine…♥”
Watching her desperately try to look tough, Kaisent smiled an unreadable smile and lowered himself to her eye level.
“As I said earlier, I originally came to talk with you, big sister. What just happened was simply me helping because you looked like you couldn’t hold your lust back.”
His smile was warm and friendly, yet Lilith found it deeply ominous.
“Big sister. You once told me you were tricked by cultists and died fighting for them.”
“Huuuk… and?”
“No matter how I think about it, it doesn’t make sense. You wanted so badly to return to your original world that you even threatened me. So why did you fight to the death on the cultists’ side?”
The pointed question poured cold water over the heat that pleasure had poured into her brain; clarity returned in an instant.
“They deceived me.”
“They proposed fighting in an underground space with no escape routes?”
“They said there was an exit. I only learned it was a lie later.”
“The moment you learned I was receiving support from my father in another dimension, you immediately pointed a weapon at me and threatened me—so you could go home.”
He had turned the matter over from every angle; Lilith fighting to the death alongside cultists simply did not fit.
“The you I know would have attacked the cultists instead and desperately explained that you were a different race who didn’t understand this world and had been tricked. That would have given you a far higher chance of survival. Yet you fought with them until your life ran out. That means—”
Kaisent held out the back of his hand, where a strange sigil was etched.
“It was because of this, wasn’t it?”
“I have no idea what you’re talking about. At the time I was desperate; I had no room to think about anything else.”
Even as her heart lurched, Lilith kept a perfect poker face—so perfect a stranger would have believed her.
Kaisent simply poured inner energy into the sigil on his hand and spoke.
“Big sister. Remain erect for the rest of your life.”
“!!”
Chiiing!
Light flared from the mark and sank into Lilith’s flesh. From this moment until she accepted a new master, she would live in a state of permanent erection.
“Y-you… how…!?”
“I figured that if there was a reason you had no choice but to fight, the answer would be here. Fortunately it wasn’t some impossibly complex mystery, so even someone with little magical knowledge like me could figure it out easily. Being the owner of the mark helped, of course.”
“Kkh…!”
“But it’s really too much. As a summon you obviously knew about this, yet you stayed silent. At this point it’s no different from a lie.”
“That’s…!”
Click! Bzzzzzzzz!!
“Ohiiiiik!!”
Kaisent ignored her excuses and flipped the switch. Time had refilled her balls with semen; the violent vibration now churned that semen into a frothing storm that battered the insides of her sacs.
Just as you said, Artemis.
—Leave the rest to Arty. I recommend you sleep so you can match this world’s living rhythm.—
Yeah. I’m actually getting a little sleepy myself.
“Arty, spare switches and a magic item.”
He handed her extra switches and a silencing magic tool.
“The item will last about six hours. Unleash all the anger you’ve been holding until the others wake up.”
“Yes, Master. I will thoroughly ‘educate’ her so she never lies to you again.”
“Mm. I’m going to bed. Good work.”
“W-waaaait♥ o♥ oheyahhaaang♥”
“See you in the morning, big sister. If it had been a white lie or a lie to keep things from getting complicated, I would have understood and let it go. But a lie told purely for your own benefit… I can’t forgive that.”
Lilith desperately tried to grab the vanishing Kaisent and plead, but—
Ziiiiiiing!!
“Ogeeeeek♥ ogogogooooh♥♥”
—Arty cranked the vibration to maximum and Lilith collapsed in the very posture she had used to reach for him.
“Master is young and kind-hearted, but once he makes a decision he never reverses it. You should have told him everything from the start.”
Even if the absolute command authority was absurdly unfair, wariness after being burned by it was understandable. Still, she had attacked first, already lacked trust, and then lied on top of it. Kaisent no longer expected any voluntary cooperation from her.
“This is a first for me.”
Left alone with Lilith, Arty wore a wicked smile she had never shown anyone before.
“I never knew tormenting someone without killing them could be this enjoyable.”
“Hhigiiik♥ s-stop iit♥”
Watching Lilith writhe and beg under ball torture, Arty finally understood what it meant for one’s spine to crawl. She switched the device off.
“Haah♥ hak♥ hihk♥ hkyaah!?”
Just when Lilith thought she had been spared, Arty seized the glans in a crushing grip and began rubbing the urethra with her index finger.
“How does it feel? You want to shoot your semen cleanly out of this hole, don’t you?”
“A♥ nooo♥”
“You came from ball vibration just a moment ago and still won’t admit it.”
Thrust—!
“Kkiiiik!? Hgyaah♥”
“See? Coated in semen and precum, my finger slides right in.”
Lilith’s cock was larger than Kaisent’s; the first joint of Arty’s index finger entered with ease.
“And because I am a machine, I can move in ways no human ever could.”
With her finger still buried in the urethra, Arty began vibrating it at the same high frequency as the ball-torture device.
“Kkhiik! Hhuk! Huk! Hgaaaah!”
A place she had never even imagined. A place nothing foreign should ever enter. A sensation utterly unknown. The feeling of something thrusting and vibrating inside her urethra made Lilith grab Arty’s arm and try to tear it free.
“Oot♥ ooooh♥ hogoook♥”
But the sensation swiftly turned to pure pleasure and then to the urgent need to come.
Squelch! Vvvvvvvvvvvv!
“Kkeuh! C-coming♥”
The second joint of the finger pushed in and the vibration intensified; climax surged—yet Arty’s finger plugged the urethra completely. Semen boiled and churned inside the shaft with nowhere to go. Lilith thrashed, trying desperately to pull the hand free.
“No. From now on you may not ejaculate without my permission.”
“You… hgeuuuuh♥”
The humiliation of having even the freedom to come controlled by a machine, combined with the agony of denied orgasm, brought tears to her eyes and pushed her face to the brink of breaking.
“Fufu, fufufufu, hahahahahaha! How unsightly—drooling, crying, eyes about to roll back!”
“P-please! Let me come, let me comeee!”
Until now Arty the Machinaroid had only ever followed orders. Watching someone suffer so violently because of her own actions filled her with a pleasure she had never known. That uniquely intelligent-being joy began rewriting her entire worldview.
“You look so pitiful when you cry like that. Shall I pull it out slowly?”
“Aaaah! Aaaaaah!!”
As Arty began withdrawing the finger millimeter by millimeter, the trapped semen surged upward. The promise of imminent release flooded Lilith with pure rapture.
Thrust—!
“Kyaaaaah~~~~!!”
Arty shoved the finger back in, forcing the semen deep into the base of the shaft again.
Click! Bzzzzzzzzzzzzzzzz!!
“Kkyaaaah! Ahn♥ ooooooh♥ d-dying♥ I’m dyinggg♥♥”
With the cock sealed by a finger and the ball-torture device roaring at full power, the desperate need to ejaculate transformed into pure agony that ate away at Lilith’s reason. Her brain felt like it was melting, every nerve burning, her marrow dissolving into pleasure so intense it was indistinguishable from pain. Moments earlier she had still felt shame and humiliation; now only one thought filled her skull: Please let me come.
“If your cock breaks, Master will have nothing left to play with, so I’ll show mercy here.”
The moment the finger was yanked free, a massive geyser of white semen erupted with explosive force.
“Ogooooooh♥ ooooh♥ hoook♥ ogeeeek♥”
All the semen that had been forcibly suppressed burst free at once. Lilith’s eyes rolled white as she experienced a climax beyond anything she had ever known, continuously pumping out rope after rope.
“Hik♥ hiik♥ hahik♥ haah♥ hak♥”
She came like she was pissing, eyes flipped, tears and drool streaming down a completely ruined face, body going utterly limp.
“The hole is gaping so wide I can see inside. Not bad for a first attempt.”
Arty smiled at the masterpiece she had created.
“Did you know? All of that took only seven minutes and twenty-four seconds.”
Her internal system clock had zero error even to the hundred-thousandth of a second. Lilith, however, could only gasp for air with a thoroughly broken expression, looking ready to pass out.
Crunch!
“Kkyaaaaaaah!”
“Isn’t it basic manners to listen when someone is speaking to you?”
Arty planted her heel on the spent cock and ground it with measured force, rotating her ankle so the pressure struck from every direction.
“Kehk♥ hehuk♥ kkeuh♥ keuhk♥”
“Heh heh heh. Feeling pleasure instead of pain when your cock is stepped on… your masochism exceeds even my expectations.”
She lifted her foot, flipped Lilith onto her stomach, and draped both of the dark elf’s legs over her own shoulders.
Thrust—!
“Hhoooooh♥♥”
“Master told me you have a prostate. Today I’ll torment every single spot evenly.”
“Kihiiik♥ th-there♥ stop poking♥ stop iit♥”
Arty shoved fingers into the pussy, found the prostate and began jabbing it upward while her free hand seized the cock, aimed it straight at Lilith’s own face, and started a ruthless handjob.
“Hhaaaaah♥”
Pshuuuuut—
Simultaneous assault on prostate and cock made her ejaculate like a premature shooter; the thick ropes hit her own face dead-on. The scent of her own semen so close, combined with the permanent erection forced by Kaisent’s absolute command, dragged her deeper and deeper into pleasure—pleasure so intense that even the blood of the Demon King of Lust that had slept inside her rejoiced.
