The Fall of the Silver-Haired Rogue Nina
"What?! That wasn't the deal!"
The Demon King merely shrugged.
"I promised I'd release her in one piece, not that I'd let her go unfucked."
"You liar! Fraud! For someone who calls himself a king, does nothing but deceit and bullshit spill from your mouth?!"
"Oh, is that so~?"
The Demon King let out a booming laugh that set his azure flesh trembling, then turned his gaze upon Lord Morrich.
"Well, a promise is a promise. Fine. I will release your wife unharmed." He chuckled darkly. "In exchange, I shall kill you."
"Wh-what?!"
"Am I wrong? I never promised to spare your life."
The Demon King sneered malevolently, raising his razor-sharp claws as he stepped forward, and screams echoed throughout the subterranean dungeon.
"W-wait! Stop! Don't touch my husband! I-I'll do anything, just please—!!!"
He paused.
"Oho. Any. Thing?"
"No, don't!!!! Nina, stay out of this! You cowardly bastard! Keep your hands off Nina!"
"I already told you, I won't touch her—I'm touching you. I'll tear your heart out while you're still breathing. Thump, thump. Watching that hot heart pulse right in the palm of my hand."
"Kheheheh!"
Chuckling gleefully, the Demon King raised his hand, casually flexing his claws into a fist and relaxing them again.
"And then I'll hand your corpse over to Sandro so he can make good use of every scrap."
Crunch.
The Demon King's talons slowly gouged into Lord Morrich's chest. Fresh blood welled around the tips, mirrored by the bitter, bloody tears gathering in Nina's eyes.
"Nooooo! Please, please don't hurt my husband! I'll do whatever you want!"
Banging frantically against the iron bars, the silver-haired rogue wept and pleaded. Bound tightly in coarse ropes, I could do nothing but stand there, semen still leaking from between my thighs, dirtying the ruined wedding dress.
"Kheheheh. Then how about we make a little wager?"
A wager?
"As it happens, that little breeding bitch of mine over there is in dire need of a good teacher."
The Demon King pointed a claw at me, trailing a finger slowly across my lower abdomen. It was a sickeningly ticklish, crawling stroke. So vile, so humiliating...!
"Silence them both."
In an instant, thick gags were shoved into my mouth and Lord Morrich's.
"Mmph! Mmmph!"
"Be quiet, the both of you. Hey, thief. Your name was 'Nina', wasn't it?"
"...Yeah."
"You're the bitch who's been bleeding my legion of intelligence and war funds. You've given me quite the headache, you know. It's high time you paid the price. Fufu. So, shall we play a little game as your punishment?"
A broad grin stretched across his face.
"If you can endure my caresses for one hour, I'll release your husband."
"—!!!"
"Ah, don't fret about failing too quickly. I'm a gentleman, after all—I won't give you just a single chance." He smirked. "If I make you cum thirty times or more within that hour, I win."
"Hah! Thirty times? As if! I won't cum even once, so save your breath!"
"Your husband's life hangs in the balance. Think carefully before you speak."
"...Fine. Thirty times." Nina glared at him through strands of disheveled silver hair, gritting her molars tight. "Just do it where my husband can't see."
"Mmph! Mmmph!"
"...Don't worry, honey. There's no way in hell I'd ever get off to a filthy demon."
Her eyes burned with pure hatred.
"Not that it'll ever happen, but how are you even defining 'cumming'? You're not going to pull a half-assed trick and claim I did, are you, you vile bastard?"
"Have no fear. In response to your brainwaves, this tentacle creature goes mad with the urge to breed and flashes light. We'll count by its flashes."
"...Fine. You aren't using drugs or magic, are you...?"
"None whatsoever. I swear it upon my status as Demon King."
At that, she forced a brave, reassuring smile.
"Don't worry, sweetheart. I'm sure he's waaaay clumsier than you are. I'll be back in no time. I love you."

"Mmph! Mmmph!"
Clank.
The iron gate swung open, and the azure-skinned demon, without a shred of clothing upon his colossal frame, slung an arm around the silver-haired rogue's shoulders and escorted her out of the chamber.
"Fuhuhu. Care for an amusing piece of wisdom beforehand?" He grinned wickedly. "From time immemorial, imagination has always been far deadlier than poison."
What the hell is he talking about?
"And imagination feeds upon hearing. Prick up your ears and listen closely. Bwahahaha!"
Leaving behind those cryptic words, the Demon King vanished into the adjacent room, leaving me behind with Lich Sandro, Lord Morrich, and the skeleton soldiers.
Hearing? Imagination? ...Don't tell me!
The dreadful realization came to pass almost immediately. This was an enclosed underground dungeon, hollowed out like a cavern where sound bounced and multiplied. If the room was right next door, how could the moans not carry over?
For the first ten minutes, absolute silence reigned. Then, five minutes later, a muffled sound hummed through the rock.
—Ah...!
Lord Morrich, sitting right in front of me, visibly flinched. Had I heard wrong?
—Nnh...! Nn-aah...!
"......"
It was no mistake. It was unmistakably the voice of a female desperately clenching her teeth, doing everything in her power to swallow her whimpers. The sound resonated clearly throughout the dungeon. Just what in the world was happening in the room beside us?
—...Ah! ...Ah, ah!
The intervals between each gasp were shrinking. Barely half the time had passed, yet like the heavy, reverberating footfalls of an approaching giant, Nina's whimpers echoed through the entire hollow.
—...Nnh, ...ah! Aah...!
At first, it had been nothing more than faint groans trickling past clenched teeth.
—H-hyk, hyk, hyeeeh?! Nn-aah...!
Gradually, her lips parted, and her breathing turned ragged. The pitch rose into desperate panic.
—Hah, hah, hah, w-wait, slower... nnh, aaah, no, not there, please, I beg you, stoooop!
A breathless scream tore through the air. I recognized that desperation all too well; I had just lived through it myself. Even if he wasn't penetrating her, he was undoubtedly toying with Nina using overwhelming, dazzling technique. Just as he had played my body like an instrument, he was deliberately molesting a married woman so her husband would hear every sound!
—Haa, haa, haa, haaaah... honey, I'm sorry, I'm so sorrryyyyy!
Her wail shook the hollow chamber.
Flash!
A blinding radiance burst from the adjacent room—a glow so fierce it seared against the eyelids even when shut tight. As the light flared, the skeletal lich standing beside me muttered in a chilling monotone.
"One."
Veins bulged red in Lord Morrich's eyes.
"Mmmrph!!!!"
He thrashed violently, but his struggles were entirely futile. The gag choked his furious screams into swallowed rumbles, and twisting his bound limbs only carved the ropes deeper into his raw skin. What kind of torment was it to sit powerless while your wife was degraded mere paces away? Was it worse than being forcibly turned into a woman and publicly bred before your allies? I honestly couldn't tell.
That was how the world worked: the first time was always the hardest, and everything after came easy. Or rather, a first time might stand alone, but a second was guaranteed to invite a third. Forced climaxes were no different.
Schlick, schlick...
A faint, wet squelching began to drift through the corridor.
"Mmm-uuugh!"
Realizing what the sound meant, Lord Morrich scrambled to his feet, only for a skeleton sentry to kick his legs out from under him, sending him crashing back to the floor. Meanwhile, the wet sounds grew sharper, distinct.
Schlick, schlick, schlick.
Her pussy was soaking through. The Demon King's seed still inside me had turned translucent, trickling down my inner thighs, and the sheer memory sent a repulsive shudder through my flesh. He had promised only caresses, so there was no penetration. That meant this wet sound was purely Nina's own arousal...!
Schlick, schlick, schlick.
The pace quickened, joined by a bizarre nasal hum.
—Ah...!
It sounded different from before. Though she was clearly fighting to suppress it, the pitch was noticeably higher. I knew that sound. It was the noise a woman made when she could no longer control her boiling body, utterly overwhelmed by hormones.
—Ah, ah, ah... ah~!
A sweet, breathy whimper leaked through her teeth.
Flash!
Once again, the cavern was bathed in brilliant light as the tentacle creature detected the brainwaves of her orgasm and reacted. Beside me, the skeletal lich murmured dryly once more.
"Two."
"Mmph!"
"Be silent. You know the truth as well as I."
Though he was nothing more than animated bone, Sandro's hollow voice dripped with mockery.
"Pleasure is like an avalanche. Once it begins to slide, it cannot be stopped."
His words proved undeniably true. It had taken fifteen agonizing minutes for the first whimper to escape her, but barely two or three had passed between the first climax and the second. A faint glimmer of desperate hope flickered across Lord Morrich's bloodshot eyes.
Could she still hold out? Thirty was a large number, wasn't it?
It was a fatal miscalculation.
Schlick, schlick, schlick, schlick!
The wet squelching crescendoed.
—Ah, aah, aaaaaaah!
Half scream, half ecstatic groan, her voice tore through the hall, accompanied by the wet spray of leaking juices.
Flash!
"Three."
The interval between the bursts of light shortened drastically. Not even thirty seconds passed between flares, let alone a minute.
"Four, five, six."
"Mmmph! Mmph!"
"Do you wish to weep? Pathetic. Why not stroke your cock right there, picturing how your wife comes?"
"Mmph, mm-uuph!"
"No woman has ever failed to climax under His Majesty's touch. He knows precisely how to tame a female's body. Kheheheh, if she submits properly, she might even earn his favor. Wouldn't she be happier that way? No? Well, let us see how long your wife can endure."
"Mmph! Mmmph!"
Lord Morrich's desperate flailing froze solid at the voice echoing from beyond the cave wall.
—Honey, I'm so sorry! Th-this doesn't feel good at all, not one bit, aaah, I'm so sorrryyyyy!
From that moment on, it turned into an uninterrupted cascade of light. Like flashes erupting from a wall of press cameras before a movie star on a red carpet, the cavern pulsed incessantly with the radiance of the brainwave-reading tentacle beast.
Flash, flash, flash, flash!
"Seven, eight, nine, ten, eleven, twelve..."
—Hyk, eek, hyk, not there, don't lick that! Even my husband has never licked... ooohhh!
Splash...!!!
Flash, flash, flash, flash!
"Thirteen, fourteen, fifteen, sixteen, seventeen..."
It was over. She couldn't come down from the crest of the climax. I could understand a fraction of what she was going through. Though mine had been violent rape, I had brushed against the terrifying edges of that overwhelming pleasure. Riding that wave was inescapable; once you were caught in the surf, you were forced to ride it until you capsized. Even without seeing it, the scene was vivid in my mind: Nina's lithe, supple body writhing helplessly up and down...!
—That's not where you lick! Don't put your tongue in! Don't put it innnn! Aaah, no! Don't stir it, please! Please, I beg you! I was wrong, I'm so sorryyyyy!
Flash, flash, flash, flash!
"Twenty-five, twenty-six, twenty-seven..."
"Mmmmmph!"
Driven mad by the lich's count, Lord Morrich lunged upward. Before the skeleton guard could kick him down, he hurled his head toward the stone wall.
Crack!
Skull slammed brutally against stone. Incapable of enduring the sheer misery, he was attempting to take his own life.
"Oh dear. Did you hate hearing it that much?"
Yet it was utterly pointless. The entity standing before us was a master of flesh modification, a monster known as the 'Corpse Collector'. Sandro calmly summoned strands of magical thread, stitching the split skull back together on the spot.
"Mmph, mmph!"
"I would gladly kill you and turn you into a marionette, but where would the fun be in that? Keep your mind intact and listen to those sounds. Isn't it magnificent?"
—Aaaaaaahhhh~!
The cavern was filled again and again with blazing white light. Soaring far past thirty, the cavern continued to pulse with blinding brilliance, over and over, until the hour finally expired.
