A Heartless Bitch Deserves Proper Discipline
Succubi.
Ever since the Demon King first forged his legions, their lineage had been cultivated for a singular purpose: to harvest Negative Energy from sentient life. Their nature was fundamentally sadistic, and their talents—namely glamour and hallucinations—were specialized in cornering mortal minds into psychological ruin.
Wielding these gifts, they would approach their marks under the guise of harmless innocence. They bestowed warm favors upon their prey, patiently sowing the seeds of anticipation and hope. Blessed with beauty capable of captivating any heart, they projected an aura purer and more noble than any holy priestess, melting away all suspicion. And once that gap had closed, they steadily drew out romantic longing...
Yes, every last bit of it was nothing more than an act.
Just as the fall hurts far worse the higher one climbs, their betrayal was meticulously timed to strike at the peak of hope, plunging their victims into the darkest depths of despair. Those who fell hopelessly in love were utterly broken upon witnessing their true nature, and the resulting torrent of negative emotion served as sustenance, currency, and proof of achievement for the succubi. That was their race: the most selfish, sadistic creatures in existence, driven solely to drag others down into misery.
Naturally, anyone who graduated at the top of her class from the specialized Intelligence Training Academy would possess a heart brimming with pure malice, dedicated entirely to casting victims into the abyss.
"Aha-ha! Look at that face! You’ve gone completely pale! Did you really think you were getting into bed with me? Did you honestly imagine we’d have a sweet little baby together and live happily ever after?"
Having finally dropped her masquerade, Catherine unhesitatingly spewed heartfelt mockery at the Dungeon Master who had sought to hire her.
"Too bad for you! A noble, exquisite creature like me would never match up with a pathetic, pig-headed freak like you. Hahaha!"
"...Hah, haha."
Did she find her own nature that hilarious? As her grating jeers rang in his ears, Bertin let out an empty chuckle, letting his betrayal show.
"So Lufo wasn't warning me for nothing. To think you’d be such a hypocrite, toying with a man's feelings like this."
"Well, of course I would! What woman in the world would ever want to bear children with a filthy pig like you? In that sense, shouldn’t you be thanking me? Shouldn’t you be down on your knees, grateful that I gave you a reality check right now?"
"Grateful, my ass... Urgh!"
A vicious kick caught him flush, sending Bertin helplessly tumbling across the floor.
Retaliation was currently out of the question. His limbs were completely soaked in the paralyzing aura unique to succubus mana.
"You should be thanking me. If I hadn’t done this, you’d have spent the rest of your miserable life deluded into thinking there was someone out there who could love an idiot loser like you. In a way, doesn't that make me your savior? Kyaah~ Aren’t I just the sweetest thing?"
Not a shred of her earlier innocence lingered in that shameless self-praise. Pushed past the brink of betrayal, Bertin ground his teeth and spat out a succinct verdict.
"Fucking bitch."
Smack!
A sharp strike whipped his head to the side.
"'Fucking bitch'? Watch your tongue. Show some respect—I’m your Master now."
"Master, my ass—"
"Uh-uh! Did the pig just talk back while its Master is speaking? Looks like I need to beat some manners into you!"
Smack, smack, and then crack!
Open slaps quickly turned into closed fists pounding against his skull, battering his face into a bruised mess in seconds. It was relentless, unadulterated violence. Yet far from feeling a flicker of guilt, Catherine's eyes sparkled with an ecstatic, tingling thrill.
"Ahhh~ this feels so good on my knuckles! You know, our little piggy, looking at you now, maybe your true calling isn't being a Dungeon Master, but a punching bag! If you got a job at a fighting gym letting people beat you for cash, you’d make a fortune! Pwahaha!"
Ptui.
Bertin spat out a mouthful of bloody saliva. Still paralyzed, he glared daggers at her, issuing a low warning.
"Catherine... do you really think you can handle the fallout from this? Lest you forget, I'm the one hiring you."
"Oh my goodness, whatever shall I do?! How could I possibly commit such insolence against my heavenly employer?! I’m sooo sorry~ My mistake~ Please forgive me just this once, pretty please~~!"
Her apology dripped with heavy, playful mockery. Then, a cruel sneer spread across her lips.
"...As if I’d ever say that, you retard! Pwahaha! Listen to yourself talk! You're a third-rate scrub with zero backing, buried in debt just to keep this obsolete relic of a dungeon afloat!"
Thwack!
Another brutal kick dug into his ribs. There wasn't an ounce of mercy in her blows. Rolling pathetically across the cold stone floor was the height of humiliation—and the dark, bitter emotions bleeding from him served as the finest nourishment for a succubus like her.
"Listen up, 'Boss'~ You clearly don't know how the real world works. Even without you, a top-tier graduate like me has people lining up around the block to hire me, you know?"

"In fact, for us succubi, having a track record of utterly humiliating someone like this is literal proof of excellence! Do you have any idea what that means? Screwing you over is experience! It’s credentials! It’s a shining achievement on my resume! Get it!?"
"Guh...!"
Catherine straddled his fallen form, driving her full body weight down onto him. As the crushing pressure forced a groan from his chest, an intoxicating flush rose to her cheeks at the sight of his agony.
"Ahhh~ that is a lovely expression. After all, happiness is far too luxurious for a pig, isn’t it? A pig's true purpose in life is to fawn and beg while taking a beating from its master!"
"Could you quit calling me a pig? I’m—"
"Excuse me? Did you open your mouth? Did you dare speak without your Master's permission?"
Slap, slap! Another pair of stinging strikes shut him up. Yet it wasn't enough to satisfy her; her fingertips twitched with escalating sadism.
"A pathetic piece of shit running a worthless hole in the middle of nowhere, and you dare put on airs with me? You moron~ Losers like you should just bury your noses in the asses of noble beings like me and lap up our sweet nectar~"
She pressed her hips down harder, grinding her weight into him to rub in the humiliation. Her intention was purely to degrade him, but hearing those words triggered an entirely unexpected reaction across his battered face—a distinct flicker of arousal.
"Well... that’s actually pretty hot."
"Huh? What the hell are you—wait."
Catherine paused, feeling something firm prodding against her thigh. She glanced down. There, inside his trousers, was an unmistakable, massive bulge tenting the fabric. Staring at it, Catherine’s eyes flashed with greedy anticipation, assuming she had discovered something valuable.
"Oho, hiding something down there, are we? Don't tell me you stashed a gold bar in your pants?"
"H-Hold on. Not there...!"
"Shut up and stay still, piggy~ If you have something precious, you hand it over to your Master! Now, let’s see what we have h—"
Yank.
"...Eh?"
The moment his pants were yanked down, a thick, monstrously engorged rod sprang free into the open air. Catherine froze, staring blankly for a second before realizing that this imposing pillar of meat was attached directly to his groin. Fluster quickly gave way to bewildered panic.
"Wha-What?! Wh-What is this?! G-Genitals?! Why the hell are they so huge?! Do you have a tumor or something?!"
"Pfft. A tumor? Don't tell me our great 'Queen' has never seen an erect cock before?"
"An erect... what?"
"Ha! Acting like some grand queen bee, and you’re still an untouched virgin who hasn’t even popped her cherry? I can already tell how pitiful that pussy of yours is without even looking."
Even if she didn't fully grasp every term he used, she could clearly tell she was being insulted.
"Y-You dare look down on me, you pig?!"
For a succubus whose entire existence revolved around degrading others, being ridiculed herself was an unforgivable offense. Infuriated, Catherine lashed out with a vicious kick straight to his gut, sending Bertin skidding hard across the room until he crashed against the far wall.
"You miserable swine! What’s there to brag about having a grotesque monstrosity like that?! Erections? Virgins? Babbling nonsense only you understand! Do you think I'd bow my head to that?! Oh, absolutely—scum like you are always the same! Snickering over inside jokes to stroke your pathetic ego, only to get your ass kicked! That’s why you’re drowning in debt running a piece-of-shit dungeon like this, isn’t it?!"
She vented her fury, shouting down at him to rebuild her bruised pride. She fully expected her tirade to break his spirit. Instead, the man wasn't even listening. He was grinning.
Though the paralysis hadn't fully cleared, her rough treatment had conveniently flung him right next to the switch controlling the defenses in his quarters.
"Hey... did you forget whose room you're standing in?"
"What other bullshit are you trying t—"
Pssssssshhh!!
The instant the switch clicked, a cloud of vivid pink gas erupted into the chamber. Caught off guard, Catherine inhaled a lungful and broke into a fit of coughing, pure shock seizing her voice.
"Cough! Wh-What is this?! Poison gas?! You bastard, using a trap...! Kh!"
A wave of dizziness washed over her as an unnatural heat began to simmer deep within her flesh. Holding her breath came too late; the entire room was already thick with the vapor.
"In case you didn't know, I'm a certified trap architect. I rigged my private quarters to the brim. And right now? Every single trap in this room is armed. Know what that means? Take one wrong step, and you're royally fucked, you bitch."
"Cut the crap! I'll just walk right out of this dump—!"
Furious, Catherine lunged toward the exit. Yet the moment her fingers grazed the doorframe, the mechanism rigged above detonated in a blast beneath her feet.
BANG!!

"Wh-What?!"
A Disarmament Trap.
The concussive shockwave instantly shredded every thread of fabric clinging to her body. Naked and reeling from the blast, Catherine instinctively stumbled backward—right onto the pressure plates embedded in the stone floor.
Clatter, clack-clack-clack!
Traps sprang to life, whipping through the air from every direction. Catherine scrambled in a panic to dodge, but with dizziness clouding her senses and the aphrodisiac gas sapping her strength, evading an onslaught converging from all angles was an impossible task.
"Kh, ahhh! What is this?! Let me go! Untie me this instant!"
Ropes coiled tightly around her limbs, binding her securely. But they didn't merely hold her; they bit deeply into her flesh, chafing against skin made hyper-sensitive by the gas. Across her throat and breasts, her stomach and thighs—and right into the intimate folds between her legs that no living soul had ever touched.
"Th-The ropes are digging in... Nngh, ahh! Stop! Don’t touch me there—aahh!"
Creak, creak. The more she writhed, the tighter the hemp squeezed, drawing gasps and shivers from her body. Meanwhile, the paralysis having finally ebbed, Bertin rose to his feet, rolling his stiff shoulders to work out the kinks.
"Phew. Getting fully aroused really gets the blood flowing. Cleared the paralysis right out."
"Y-You bastard! How dare you do this to me...! HIIEEK!"
Catherine’s eyes widened in sheer terror as she beheld his cock, standing even more aggressively rigid than before, pointing right at her. Coupled with his clenched fists, veins bulging along his knuckles, she finally realized the tables were completely turned. Desperation forced her into an immediate retreat.
"U-Um, Boss? L-Let’s just calm down and talk this out, okay?"
"Oh? After throwing that temper tantrum, now you want to have a civil chat?"
"Eek! Why not?! Are you really going to hit a woman? You can't do that~! I'm just a frail, delicate maiden~! A real man isn't supposed to hit women, right? Right?!"
She threw on the pitiful maiden act with all her might, desperately fishing for sympathy. But there was no chance an avatar of lust, boiling with rage and fully aroused, would listen to such transparent drivel.
"To be fair, I don't care much for violence either. But when it comes to SM play, that's a whole different story."
CRACK!
"H-Hiiieek...!"
A whip appeared in his grip, snapping viciously against the stone floor. Beside him lay an assortment of ominous, specialized gear, radiating a sinister aura. A shudder of unknown dread seized Catherine's heart as he let out a ragged, lust-filled breath, an expression of dark ecstasy washing over his face.

"If you truly consider yourself a sadist, you'd better pay close attention. Starting now, I’m going to carve the meaning of true sadism deep into your flesh."
Sex founded upon sadism and masochism, absolute dominance and total submission.
The curtain had risen on their session of BDSM play.
