The (Former) Delinquent's Humiliating First Time
The demon named Lufo had not started out as a corporate sales representative for a merchant group.
In her past, she had been a mercenary renowned even within the ranks of the Demon King's Army—a mid-tier executive who reigned over multiple dungeons, standing before countless adventurers as an insurmountable wall of despair. Coupled with her overwhelming raw strength, her brutal temper made her the very incarnation of terror. Adventurers who crossed paths with her had branded her "Lufo the Delinquent" and eventually placed a hefty bounty on her head.
From the standpoint of the Demon King's Army, where instilling fear in invaders was standard operating procedure, such a reputation was considered ideal. Yet Lufo herself had never been particularly fond of the moniker.
Brawling had merely been her means of surviving the slums where she was born, and grinding her way through dungeon after dungeon had simply been the only avenue left to get ahead in the world. But now that she had accumulated a modest measure of fame and wealth, did she really need to keep risking her neck?
As a dungeon gatekeeper, she had occasionally encountered adventurers stronger than herself. Each time, she had fought desperate life-or-death struggles that left her on the brink of death with gruesome wounds. If she ended up dying like that, everything she had built would vanish into thin air.
Prize her own life as she did, a deep skepticism toward combat had taken root in Lufo's mind. Naturally, her interests shifted toward work that was relatively safe while still raking in steady profits: corporate sales. A job where she could stay behind the scenes and peddle wares without ever having her life on the line. On top of that, closing deals guaranteed substantial commissions and prestige. For someone disillusioned with violence, it seemed like the ideal career.
Yes, she had entered the business world fueled by such rosy aspirations, but...
Why is being a sales rep so much more suffocating than I thought?
Landing the position was fine, but starting at the very bottom meant her superiors constantly dumped grunt work on her desk. Worse still, over half the clients she met in the field turned out to be total nightmares. They would demand discounts on fairly priced goods, bluster about whether she knew who they were, and throw tantrums. Yet if she crushed those obnoxious bastards with brute force, customer complaints would roll in and jeopardize her performance metrics. All she could do was grit her teeth in silence and wait for a real opportunity.
Sigh. Some colleagues land deals with rising stars and shoot straight up the corporate ladder, while I'm stuck getting pushed around by broke deadbeats every damn day, sweating blood... It'd be one thing if they actually repaid their loans, but most can't even cover the interest before getting shipped off to the coal mines. Which leaves my cut looking like chicken feed.
It had been more than enough time for her idealized dreams of corporate life to shatter completely. Even so, driven solely by the stubborn resolve never to return to her brawling delinquent days, she swallowed the humiliation. Deep down, a single thread of hope kept her going: a vague, open-ended hope that she might land just one massive deal to blow the doors of success wide open.
In that context, the news that the dungeon belonging to Isabella—the premier trap architect of their generation—had reopened felt like a stroke of godsent fortune she had to seize at all costs. She had ended up saddled with this sector containing the abandoned dungeon after her boss dumped it on her, but if played right, it might just be the ticket out of her miserable rut.
And yet, who do I run into? Not Isabella herself, but a greenhorn rookie who just peeled off his graduation tag... Sigh. Of course. It's bound to be another bust.
Having weathered so many disappointments, Lufo could hardly muster any real expectations for the novice architect who had stepped up as the dungeon's new master. Apprentice to Isabella or not, novices usually thought it was a virtue to wallpaper their dungeons with mindless, lethal brutality rather than efficiently extracting negative energy. Such rookie habits would smooth out over time, sure, but Lufo, hungry for immediate advancement, had neither the patience nor the luxury to wait around.
I'll hear him out for now, but I'm not holding my breath. Sigh... Guess I should start reserving another slot in the coal mines.
As she stood grumbling with zero expectations, Bertin, having finished setting up his trap, walked over to her.
"Ah, well. It's roughly put together. Given our lack of resources, though, they're nothing particularly grand."
"Save it. A makeshift sample is more than enough for a test run."
Dismissing his modesty, Lufo strode toward the passageway Bertin indicated. At the end lay an ordinary, run-of-the-mill dungeon corridor, yet not a single trace of a trap could be sensed anywhere along its length.
Rookies usually leave telltale signs you can spot with the naked eye, but his concealment is surprisingly decent.
The concealment was so thorough it made her wonder if he had even laid any traps at all. Scanning the corridor with a practiced, hardened gaze, Lufo cast a sideways glance back at Bertin, who had followed alongside her, and spoke in a sharp tone.
"I'll tell you right now: if you fail to extract an acceptable yield of negative energy from me, the deal is dead in the water. Issuing a loan to someone without proven credit would be a massive liability for our merchant group."
"Well, if it doesn't work out, that's that. For my part, I simply hope you find my traps to your liking, Miss Lufo."
He looked remarkably composed, as if holding an ace up his sleeve. Unfortunately for him, the person he was testing them on was none other than Lufo the Delinquent, the terror of countless adventurers in her prime.
Any half-baked trap can easily be tanked with my bare body. Talk about rotten luck for this guy. Out of all the sales reps he could've drawn, he had to demonstrate his traps on me.
Blades, poisoned arrows—bring whatever you've got. I'll endure it all with sheer flesh and blood and hand you a humiliating defeat.
Click.
Armed with that unshakeable confidence, she took her very first step. The instant she felt the mechanism trigger beneath her boot, Lufo flared every nerve in her body, bracing to defend against whatever came her way. She was certain her reinforced frame could shrug off any sharpened steel.
BOOM!
Instead of a blade, a violent, gale-force pressure erupted straight up from beneath the floor.

"Wh-what?!"
The next moment, she watched her business suit get shredded to ribbons right off her body. Lufo's eyes flew wide as she stared blankly down at her completely naked self. A blast of wind instead of blades or poison? In all her active years, she had never heard of such an absurd trap.
"Looks like the Disarmament Trap worked like a charm."
"Disarmament?! You mean a trap that only strips off clothing?!"
"Pretty much. How did your first trap experience feel?"
Bertin spoke with a smug grin, holding out the energy extractor in his hand. The faint pink glow rising from the device was undeniable proof that she had felt negative emotion from the trap. And of course she had. Having even her underwear torn away meant her most private areas were laid completely bare.
Damn it... Even during my mercenary days, I was never stripped naked!
Humiliation burned through her. The fact that she had failed to counter the very first trap and ended up exposing every inch of her body stung her pride.
"Ha... haha. You think this will cut it? That's nowhere near enough if you want what you're asking for."
Despite her desperate facade of composure, Bertin casually gestured for her to continue down the hall.
"I suppose so. I've prepared plenty of traps, so please, keep going."
Damn greenhorn, acting so full of himself...
She had only been caught off guard once. From here on out, she wouldn't let her guard down for a second; she would blast through whatever lay ahead.
Naked as the day she was born, Lufo took another cautious step forward. Yet the next trap struck directly from her blind spot, instantly ensnaring her body.
Schrrrck!
Once again, it wasn't a blade, but ropes. An attack aimed not at piercing flesh hardened by demonic mana, but strictly at binding the target.
"Kh! Th-this piece of garbage...!"
Her arms and legs trussed tightly as she was hoisted into midair, Lufo scowled with burning indignation, straining her muscles to snap the bonds. Yet the ropes refused to give. With her brute strength, breaking mere hemp should have been trivial.
"Ah, you won't be breaking that easily. Those ropes have mana-sealing properties woven into them."
Are you kidding me? A mana-sealing restraint?!
Even during her mercenary career, traps like that were reserved for high-tier dungeons. Was this truly the caliber of Isabella's apprentice? More importantly, if his words were true, she was in serious trouble. Without mana, she had no means of defending herself—meaning whatever torture followed, her defenseless flesh would have to absorb every bit of it.
No, wait. Torture after capture is well within expectations. Nothing I can't handle.
Who was she? She was a savage hailed as a delinquent, someone who had butchered foes without caring if her own body was torn to shreds. She was well-accustomed to blades digging into her flesh and muscle being gouged out. There was no way a novice trap designer's torture could force negative energy out of her.
So bring it on, whatever it is. I'll endure every second of your torture with nerves of steel.
Pssssssht!
Yet what answered her defiance was not cold steel, but a cloud of pink mist. Inhaling the unexpected mist, Lufo coughed violently, crying out in total confusion.
"Wh-what is this?! Poison?!"
"Aphrodisiac gas. It puts anyone exposed into heat."
"H-heat?! What is that supposed to mean?! Losing your reason and getting aroused...?!"
"Ah, right. The concept of 'heat' doesn't exist in this world. Well, give it a little time and you'll experience it firsthand."
Bertin stood quietly by, speaking in riddles. Lufo thrashed against her bonds, trying desperately to tear them apart, but the mana-suppressing ropes rendered her struggles utterly futile. Bound helpless in midair, she could only watch time tick away as the reaction he promised began to take hold.
"Haaah... nggh, ah..."
All at once, her body flared with feverish heat, and her breathing hitched. Even though she was merely dangling in place, a faint electric current seemed to shoot through every nerve, making her entire frame shudder. Worse than the heat, however, was the unbearable sensation concentrating directly in her most intimate areas. Her previously dormant nipples had somehow hardened into rigid peaks, and from the slit between her parted thighs, a faint trickle of moisture was seeping out.

Wh-what is this? What the hell is happening to me...?!
This was unlike any poison she had ever encountered. Trapped in dizzying bewilderment without a shred of understanding, she watched Bertin saunter closer, a wicked smirk playing upon his lips.
"Hehe. Looks like the heat took hold perfectly."
"Haaah, ah... Wh-what did you do to me... Hngh~♥"
"You said anything goes for the test, didn't you? Just like you authorized, I'm going to do whatever I please with your body from here on out."
"Haaah, nnh... W-wait, if you touch me right now...♥"
Without hesitation, his hands cupped and rubbed her breasts, stoking the fire in her flesh. It wasn't violent in the slightest, but his kneading strokes were strangely practiced, sending jolts of erotic stimulation racing through her nerves.
"Haah, these breasts... I've wanted to do this ever since I laid eyes on you. Flaunting something so lewd out in the open—do you have any idea how hard it was for me to hold back?"
"Wh-what are you... Ahh~♥ W-wait! What are you doing right now?!"
"What does it look like? I'm sucking your tits. Schluuurp, mnh~♥"
"Nngh, ah... St-stop...♥"
What on earth was wrong with this man? Sucking on her breasts like some ravenous infant! To squeeze and nurse on breasts that didn't even produce milk—her face burned crimson under the one-sided assault. It made no sense whatsoever, but the humiliation of it dwarfed everything else.
"Miss Lufo."
Having thoroughly ravished her chest, he cupped her cheeks in his hands and spoke softly.
"Have you ever kissed someone before?"
A kiss. An act usually reserved for lovers harboring romantic affection for one another.
"Of... of course not! How could I have?!"
Having spent her entire life consumed by combat and sales quotas, Lufo had never had a lover, nor had she ever daydreamed about such tender displays. Yet to be kissed by a man she didn't love—even the thought was horrifyingly shameful.
"Mmph?!"
The moment she realized he was forcing it upon her, a furious rage flared in Lufo's chest. How dare he press his lips against a sanctuary no one had ever touched! She wanted to scream in outrage at the indignity, but his kiss was far from a simple press of lips.

"Mmmph... nggh~♥"
Bertin parted her lips with his tongue, sliding deep inside to ravage the interior of her mouth. This went leagues beyond any light token of affection she had ever heard of, and with her strength drained by the aphrodisiac, Lufo could do nothing but endure the invasion with her helpless body.
"Hnghh... mmph... Haaah, slurp~♥"
What was this? Could a kiss truly be this thick, wet, and suffocatingly lewd? As the kiss dragged on, she felt her mind drowning in sensation. By the time their lips finally parted, her thoughts were bleached completely white, leaving her unable to form a coherent judgment.
"Well? How was your very first kiss?"
"Uh... aaah...?"
Lufo could only let out half-delirious whimpers, her wits thoroughly scattered. Seeing her utterly at his mercy, Bertin moved between her parted thighs and began gently spreading the intimate cleft tucked between them.
"It's completely soaking wet. Looking inside... hehe, your hymen is fully intact, too."
"Haaah... N-no... That's a... dirty place...♥"
The humiliation crushed her. The knowledge that she was exposing a private place she had never shown a living soul, coupled with an inexplicable, searing shame that made her face burn like fire. Was baring one's genitalia truly this mortifying? Did this man know, and that was why he had reduced her to such a wretched, debased state?
"Well, looks like you're all prepped, so let's get down to business."
Ignoring her turmoil, Bertin dropped his trousers, unleashing the beast nestled between his legs. The instant Lufo laid eyes on the thick, towering shaft of flesh, her senses snapped back into sharp focus, panic tumbling from her lips.
"W-wait! What is that?! A-a sex organ?! Can a male organ even get that big?!"
"Hmm, who knows? I can't speak for other guys, but my body just happens to be capable of this. And starting now, this is going straight inside you, Miss Lufo."
"Going inside?! What are you even—Eeeek!"
Slowly and deliberately, Bertin dragged the thick shaft across her dripping wet slit. Only then did Lufo grasp what he meant. Confronted with a bizarre, incomprehensible act for the first time in her life, she thrashed frantically in her suspended bindings.
"W-wait! Wait just a second! What are you trying to do?! Put that inside?! Inside me?! That's absurd! I-I've never heard of putting a sex organ inside another sex organ!"
"Hehe. You might not know the details, but you've clearly figured out just how shameful it is."
Of course she had! Genitalia were hidden parts meant never to be shown, and now he was baring his own to pierce right through hers. She couldn't explain why, but every instinct screamed danger. If things kept going like this, she would lose something irreplaceable.
"St-stop... Please, just stop..."
As Lufo pleaded on the verge of tears, Bertin flashed an easy smile, resting the swollen glans against her cleft before answering.
"Sorry, but it's too late. Pulling out when a luscious virgin is laid out before me would disqualify me as a man."
"N-no! Wait—!!"
SQUELCH!

"Hgyaaahh~~♥♥"
Having lost her virginity, Lufo's spine arched like a drawn bow.
