Onaholes Are Tools
Ona holes are tools! Wiiing!
The sharp whine of a chainsaw filled the dark dungeon.
Smooth silicone blades spun at blinding speed. And Eli, wielding the chainsaw with a bright, childlike smile, inspired an inexplicable terror.
"Hero."
"Y-yeah...?"
"Grab her so she can't run."
That chillingly bright smile. Cold sweat beaded on Kairan as she grabbed Karni, who was hiding behind her.
"Eek, eeeek!"
"Heh, heh heh."
Karni struggled with all her might, arms pinned, while Eli approached with the chainsaw-dildo.
They said people unleashed several times their normal strength in desperate situations. Kairan realized it was true.
"Ah."
Karni shook off Kairan's grip and bolted. Eli flashed a creepy grin as she watched.
"Hero."
"Y-yeah?"
"You know what?"
Before Kairan could ask, Eli channeled her holy power and spoke.
"They say you get seven times your normal strength when you're raping someone."
With that, Eli vanished.
A gust of wind—whoosh—Kairan turned toward it and saw Eli chasing Karni at breakneck speed.
Chainsaw in one hand, holy power radiating from her body, she ran with mad fervor, faster than Kairan had ever seen.
"...Well, she won't die."
Kairan sighed in relief and slumped to the floor.
Anyway, it had nothing to do with her.
The dungeon's interior was a labyrinth of complexity, like ancient underground prisons stitched together. Karni raced through the twisting paths at full speed.
She didn't know why she was running. One moment she'd sensed it, the next she was fleeing.
"H-heeek!"
"Over there!"
"N-nooo!!"
She wanted to stop, but the sight of Eli charging with the chainsaw-dildo made her legs move on their own.
Luckily, the maze-like dungeon let her shake off the pursuit quickly—but
"Hic, hiiic... Sniff... "
Hiding in a secluded room, door firmly shut, Karni stifled her sobs, tears like chicken droppings streaming down.
"Where are you~?"
The whirring buzz. Footsteps accompanied it, reaching her ears.
"Found you~?"
"Hic... "

The door creaked open. Eli approached slowly, chainsaw-dildo in hand.
"Took me forever to find you."
"D-don't come closer!"
"Hehe, onaholes don't get a choice."
Wiiing! The noise grew.
Soft silicone blades spun rapidly—a slime-based concoction... right, silicone. Karni gulped, staring at the blade matching that material.
"Bind."
"Wha...?"
In her daze, Eli finished her chant and restrained Karni.
Bound by invisible thick ropes, Karni froze, helpless as Eli drew near.
"D-don't... "
"Told you, onaholes don't get a choice."
"I don't wanna break!"
"Hehe, don't worry. I'll fix you if you break."
"Eeeek...!"
Eli stroked the "Sharp Otherworldly Pussy Executioner" lovingly.
"Hehehe, the relic that drove the first Saintess to death by overwork and was favored by four popes... Ahh, using this is truly an honor."
"...You're insane."
"Now, time for pussy execution, onahole."
The soft silicone blade touched Karni's pussy.

"H-huh... "
The whirring intensified, the blade starting to move.
Spinning wildly, it ground against her pussy. Even soft silicone at that speed ravaged her mercilessly.
"G-graaaahhh!!"
"Ahaha, what an ugly face. Dozens of orgasms in seconds?"
"H-heeek♥ G-grooo♥"
Wiiiing! The grotesque roar. Love juices splattered everywhere from the spinning blade.
"Oh."
Eli watched, unfazed even as fluids hit her face, observing Karni's endless climaxes with interest.
Stacking, huh.
Pleasure built tolerance like pain. Even dozens of orgasms at once, you'd only fully feel the first ten or so. But Karni felt every single one.
No reduction, no skipping. Each peak stabbed her brain, sometimes two or three fusing into one.
Was that the power of the "Sharp Otherworldly Pussy Executioner" in her hand?
Shivers ran down Eli's spine, but she nodded—To turn the first Saintess and four popes into masturbation addicts, it had to be this good.
"H-hiiik♥ G-graaah♥ Graa♥ G-groooh♥"
"Your brain's crumbling now."
"H-hoooo♥"
Her brain shattered under the pleasure. Eli channeled holy power, restoring it while pouring in more ecstasy.
Love juices pooled on the floor. Eli healed to prevent dehydration and blessed to keep her mind from collapsing.
Smiling at Karni trapped in eternal bliss, Eli said,
"Told you I'd fix you if you broke."
"S-save meee♥ Hiiiiggggh♥"
"Hehe, no can do. Hold on ten more seconds."
"H-hee ooooh♥"
10.
9, 8, 7, 6...
Each second felt eternal.
The whirring haunted her ears, her brain rebuilt vivid and raw, her mind cycling blackout and awakening.
If hell exists, this is it, she thought—though it didn't last long.
5, 4, 3...
Still, she hated how her body went into heat even in this hell.
"2, 1. All done."
Eli withdrew the chainsaw-dildo and caught the collapsing Karni.
That gentle touch and warmth melted Karni's hostility like snow before fire, despite it being the same person who'd just damned her.
"Hic, hiiic...!"
"There there, that was rough, huh?"
"Y-yeah! S-so hard... waaaah!"
"Sorry, sorry."
No excuses, just apologies and back rubs.
Karni felt her heart melt at the simple gesture. I'm such an idiot, she thought.
Stupidly, Karenia Valkrod was gone. Now there was only the onahole named Karni and her owner.
A little over an hour later, Eli returned carrying the unconscious Karni on her back.
The height difference made it look strenuous, but thankfully no dragging feet.
"She's out cold."
"Yeah, I can see that."
Eli gazed at the prone Karni with wistful eyes.
"Thought I could inventory her since she's an onahole, but no dice."
"Well, she's still a person, sorta?"
"Shoulda broken her mind more thoroughly."
"Excuse me?"
Kairan shook her head in dismay. For the umpteenth time, she wondered if this was really a saintess.
Sighing at the earnestly pondering Eli, Kairan said,
"Catch some Maou army grunt later and test it. Or heretics—plenty around."
"Hm. Good point!"
Kairan calmed her pounding heart and stood.
Eli looked at her and said,
"Let's move. Can't stay here forever."
"What about Karni?"
"Eh, slap a basic barrier on her."
Chanting a few verses from the holy book, Eli erected a barrier.
A translucent blue dome enveloped Karni, sparkling magic circles etched atop it.
"Yep! Even the Sword Saint couldn't break it in under ten hours!"
"That's not casual."
"Hehe, kidding. But at least an hour."
Dusting off, Eli finished. Leaving the sleeping Karni behind, the two headed deeper—toward the dungeon's final room.
"Kinda creepy, huh?"
"Last room?"
"Yeah. Boss room."
Kairan exhaled deeply, whoosh.
Steeling herself, she pushed open the sturdy boss door.
It creaked open with a screeech.
Inside: a massive bed and a woman lounging atop it.
"...Who dares enter my bedchamber?"
The woman with long golden hair and purple eyes fixed on Kairan and Eli.

"I am Seraphila, empress of the great empire, Eterion."
Her eyes, brimming with curiosity, stared intently.
