PROLOGUE

You hate it here.

It’s just all plastic smiles and plastic lies.

All to keep on rose-colored glasses of pristine aristocracy.

The perfect poster family.

And yet…

You inwardly frown as your step brother carelessly throws a thin, slim envelope, with the very same hands that had caressed your sides the night before, the thing hitting your cheek before dropping to the cold, marbled floor of your cold, marbled house.

His fiancé, and your soon to be sister-in-law smirks as she goes to your brother’s side, cleavage pushed up to her chin, the only compensation for how much of a personality she lacks but you don’t dare point that out. Her red painted nails tap her lips as she folds her arms, regarding you with unbidden hostility.

If she only knew how your step brother had cum twice under a minute just by your tongue alone, or how he had uttered your name as your walls milked him dry like a madman in heat, tongue laving all over your sweaty skin, your neck, your breasts, your nipples with so much ardour that one would think he didn’t give a fuck’s worth about the woman he was engaged to.

“Fuck, good girl,” he had grunted, desire consuming his morality, “I wish to get you pregnant, sister. Just let me live this fantasy for the moment.”

And you had acquiesced, opening up your legs to accommodate his fit with a lewd, inviting, moan, clinging to him tighter as your back arched with the pleasure he was giving you, until his warm spunk had filled your gaping, weeping hole.

You weren’t ashamed to admit to anyone that you were going to bed with a man society considered as taboo—he gave you everything you asked for, after all.

Including the fifty million you had deposited in a secret bank account the night after.

You slowly pick the fallen envelope with morbid curiosity—after all, your step brother, the next Lord of your father’s marquisate would not dare cause a scandal that would end him.

You merely raise a polite brow at your step brother as he gestures for you to open it. “Go on, little dove. It’s a present.”

You hide your smirk when his fiancé bristles, pushing her tits to his side which he merely ignores as his eyes were locked on your reaction.

With steady hands, you bring out two silver tickets, the same size as the ones you had gotten from a carnival with your mother a long, long time ago when things were much simpler and you weren’t feeling detached from the world.

Your pretty orbs widen, lashes fluttering under the mid-afternoon sun as dust motes danced along to the invisible notes that this salvation has brought forth, music in your burnt out soul. Your gaze springs up to your brother’s, and a smile graces your pretty pink lips, eyes swimming with a lust-filled promise reflected in his own stare, neck bobbing, and mouth suddenly dry as you mutter a quiet thank you before seeing yourself out, a spring in your step and round pert ass on display in the shortest of dresses –one of the only in an expensive collection he had bought for you one summer ago.

The doors close to his fiance’s nasally tone, “Well, what the hell did you give that brat?”

Out in the hallway, you hum a happy tune, the concert tickets burning in your hands and a long forgotten spark in your soul.

You must remember to reward your brother later.

—

Moonlight shone through the windows, bathing the cold room in flowing, ethereal light.

A stark contrast to the bodies molded as one against the cold, cold, glass, tongues and limbs entangled.

“Y/N,” your step brother grunts as he climaxes for the third time inside your sopping cunt. He pants as his head collapses against the junction of your neck and shoulder, catching his breath.

Somehow, this tryst was more passionate than the last. There was something wrong.

“Is it true that you’re moving permanently to Seoul?” Your hands pause from stroking his beautiful platinum blonde locks, icy blue irises piercing your soul.

Ah, so this was it.

You nod unapologetically. “I am, brother. My job requires my residency there.” Of course that wasn’t the entire truth but you wouldn’t tell him. “I apologize for missing your wedding though.” You add even though you’re not. Not really. You may have loved your brother but you weren’t in love with him like he was perhaps with you.

“When?” You feel his cock twitch inside you.

“…Tomorrow.”

“What—” He sighs, then looks up, a wicked grin playing on his luscious lips—a trait that made most women swoon, but not you. “In that case, I’ll have to make most out of this then, won’t I?” He leans in to whisper, cock hardening once more and you scoff, only to throw your head back as he slams into you with a renewed fervor you haven’t seen.

“Ah! B-brother, please, harder!”

He rasps, “That’s right. Scream your throat out, know that no man on this earth can make you feel the way I fuck you senseless. “

Your back meets his chest as he withdraws out of you and turns you to face the window panes, breasts pressed against the hard surface of the glass. It was a good thing the windows were overlooking the lake so no one could bear witness to the debauchery that only the devil could muster.

His cock penetrates your folds, and your hands fly out to steady yourself, one of your brother’s arms snaking out to coax your lips to his, tongues fighting for dominance, thighs trembling. Your fingers frantically find your little bundle of nerves, desperate for some release and your step brother lets you.

“Cum, little dove.”

You shout his name just as his cock finds your cervix, maximizing both of your needy whines and moans, and you feel him fill you to the brim until his cum leaks down your legs, onto the white rug.

“Fuck! Fuck, oh baby,” he groans in ecstasy, creaming you like there was no tomorrow.

He chuckles as you shake and tremble in his sultry hold, “We’re not done yet, Y/N.”

Your clit hardens. You were fucked.

—

One thing that was a perk to being the only daughter to a rich, aristocrat father, was having a private jet at your own beck and call.

None of your family had bothered to see your departure –except for your step brother (“I am going to dearly miss my cocksleeve,” he had conspiratorially teased you and you had merely rolled your eyes, “You’re getting a wife out of this, you know,” and he shrugs, though he seemed a bit forlorn for some odd reason you could only chalk up to his loss of entertainment) pouting as you stepped onto the ramp and the plane finally flew out of the airport, and as you landed on foreign soil, you couldn’t help the mild shiver from escaping you.

Winters in Seoul were dreary after all.

You didn’t bring much. Only your credit cards, some clothes and the two tickets your brother had gifted you.

The sound of wheels rolling on the rough pavement has you turning to the man in uniform – young, roughly about your age, and with the most intense green irises you have ever seen. His gloved hands pull on your light luggage with the care of someone who had been born into buttling. He was a handsome young man in his own right.

“M’lady, where to?”

His tan skin tone is prominent surrounded by white and you blink, surprised at even thinking anything pretty. Sure, you could appreciate pleasure but never in your life had you felt enamored enough to consider anything remotely interesting—other than your brother and seven other people.

You’ve only ever been Y/N, the perpetually bored daughter of the Marquess.

Your eyes flicker to his chest, and down down down until they land on his crotch. Subconsciously, you lick your lips and your butler freezes, before deflecting your gaze with a gesture of his hands. “I’ll hail us a cab for now.”

You shrug following him, heels clacking on the wet pavement. It was snowing and you were only in a thin dress coat, completely forgetting the change of seasons. “We’ll buy a car once we’re settled.” You state, causing your butler to nod at you with a brief, shocked glance as if he were also forgetting that you came from old money and you intended to fully utilize that money.

Hmm, it seems your little butler can be trained some more.

“What’s your name?” You ask, and he freezes. It was improper in your family to learn the names of servants after all, and for you to willingly ask for it was considered ill-mannered if not downright plebian.

Such wonderful family traditions.

You inwardly scoff at the stupidity of the rules you grew up with but then again, if it weren’t for them, you would be hard pressed to do whatever you pleased.

Like moving halfway across continents to attend a concert and look for the shattered parts of your soul because what else could be the reason for your listlessness, your lack of pleasure for most things other than sex, if your soul was complete.

“N-nox, m’lady.” He stutters out, nervous, as if someone would reprimand his fuck up.

You place a gentle pat on his shoulder and he shrinks from your touch, only to relax when you say, “Alright, Nox. Despite being my butler, you are to treat me differently from now on. You are my employee, not my servant and you may respectfully call me out for my mistakes as I am allowed to do so for yours, am I understood?”

You look to the darkening sky, arms folded. “And I shall take care of you as you care for me. It’s a give and take principle, got it?” You search his eyes and are surprised to find them glowing under the dim light.

As if he wanted nothing more than to devour you.

He smiles, genuine, and strangely affectionate. “Yes, m’lady.”

You nod, satisfied.

—

It is three days before the concert and a month since you uprooted your old, uninteresting life.

Your step brother occasionally calls you but then you hear his wife mewling in the background and you surmise he must be happy to even let that slag of a woman touch him.

Nox has also proven himself to be a loyal butler.

And an even better lover.

Or at least that was the term you would stick to because you weren’t necessarily in a relationship of sorts. Maybe a fuckbuddy? Whatever it is, the man was stupendously fantastic at eating you out.

“Fuck, m’lady,” he rasps underneath you, mouth glistening and you bite your lips, letting out a huff. You twist and pin him down onto the club’s nasty, grimy toilet, uncaring if you were fucking inside an unsanitary place. All you could think about was getting dicked down, too lost in a hazy lust-filled euphoria. But you knew something was missing. You just didn’t know what.  “Let me.”

With a swift stroke of his cock, you sink down onto his throbbing, weeping member, the both of you moaning in unison. “Fuck.”

Nox grips your hips and slams into you at a wild pace, teeth biting your hardened buds and you shiver in delight.

You both freeze as footsteps enter the dirty bathroom. Well, at least your stall was farther down so they couldn’t have heard. Nox however teases you with his dick and you glare down at him at the intrusion, clamping a hand on your lips to muffle a squeak because it was just that good. You roughly tug at his hair and he suckles on a breast in retaliation, eyes closing as pre-cum spurts out of his tip.

“Have you fucking seen those hot dudes?” Someone speaks and you surmise she was talking to one of her friends.

“I mean come on, who wouldn’t want to climb them like a tree? And there’s seven of them, but they won’t let anyone come near, it’s frustrating!”

“You’d think they were gay or something.”

Their laughter grates on your nerves and you are only glad when you are once again left alone, the doors closing to drown out the booming jazz from outside.

“Cumming, m’lady!” Nox bursts into your core and you shake, spurned on by his hot release. His tongue chases your own, you spend another good minute kissing until he pulls out, the condom he used thrown into the bin (for some reason, your butler always insists on using a condom with you), and he fixes the both of you, wiping you down with a few wet tissues he carries around.

You laugh as he grazes your most sensitive part. “Keep that up and you’ll get me naked again in no time.”

Your butler could only blush—always so shy and adorable after fucking.

You take his hand and weave through the crowd, unaware of seven jealous gazes following you on your way out.

—

Ecstatic could not even begin to describe how you feel.

It was your first ever BTS concert after all.

Standing at the VIP section, a couple of curious fans were side-eyeing your choice of outfit and lack of an army bomb.

While they were wearing varying fancy attires, you were in a simple one-piece high neck dress and tennis shoes, hair tied up in a purple ribbon. At least your butler had insisted on setting you up with fancy make up and freshly painted nails.

Or maybe they were staring at your handsome butler. After all, he used to work as a runway model until he saw just exactly how much your family paid the staff. 

“M’lady, twelve o’clock.” Your attention is diverted to the stage just in time as seven shadows emerge.

All earth bound creatures, piercing you with a gaze so deadly, so all-consuming that you could only gasp, core drenched, weak and wanting.

You would pant like a bitch if you could.

One of them stalks forward — a graceful black panther, bending down to whisper to one of the guards lining the edge of the podium and then points to you.

He lifts his feline gaze, trapping yours.

Your soul catches on fire.

—

A week later…

You collapse against a broad chest as you are thrown into the precipice of a never ending composition, sore from screaming and from the intensity of the love overflowing your soul.

It was as if you hadn’t lived a life not worth living.

It was as if all of your lack of selfcare, your detachment to all earthly things hit you at once with so much force you were going to pass out.

What were you doing before them? You were dead. You were existing but inexistent. Nothing made you truly feel the happiness you were experiencing now.

Not even with the money you had in your hands.

Nothing and no one could have opened your senses to this kind of insanity.

Lips crash against your own, hands groping and caressing from all sides, as nimble fingers strum your clit, the final one of your soul bonds, your twin flame slotting himself between your trembling thighs, cum running down your cunt in waves.

Yoongi smiles at you. Tender adoration in his eyes. “Can you take one more, my little Acedia?”

All of them have somehow taken to calling you Acedia and you can’t help but think the name fit you perfectly—you who had been the epitome of it for so, so long.

You nod, hissing as his thick ridged cock enters you while the rest of his brothers watch with a satisfied sort of demeanor, satisfied for having each taken their turns to fill you with their seeds.

To give you their spawn.

To bathe your insides in their cream. 

Water spills over the edge of the of the large tub as your boyfriend rams into you, and you think you’re imagining seeing two horns peek out of his head when he cums.

He licks his lips, devouring your mouth as his veiny hands play with your tits. Jimin who had been holding onto you tightly throughout moans into your ear, cum splattering your back just as you orgasm.

“You okay, baby?” Hoseok pants from above you, his own shaft in his hand, thick ropes of spunk meeting the cold, cold tiles.

You smile sweetly up at him while Yoongi noses your neck, taking the time to compose himself for another round.

Namjoon kneels by you, asking for a kiss and you give it to him delicately, bones feeling like jelly so Jimin keeps his fingers splayed gently on your chin.

You mewl when your leg lands on a shoulder and it isn’t Yoongi but Taehyung who replaces him, kissing your breasts possessively. “You are so beautiful, our love.” He massages an ankle and you release a sigh.

Jungkook takes his place next to Namjoon and pouts at you, sticking his tongue out only for you to smirk and tug at it but then he’s jumping in the tub and you shriek when he snatches you from his hyungs, landing you on your bare feet, only to be caught by Jin and the others, the elder smacking your ass before pecking your lips and tugging you into the bedroom for round two.

—

“What the fuck are you—”

“Darling!”

Horrifying screams pierce the night as seven men stare boredly at the piece of shit laying on his own pool of blood, crotch mutilated into a disgusting mixture of semen and fats, his blonde naked wife cowering on the side.

“That’s what scum like you get for touching what is ours. “

“Yah, Namjoon did you really have to destroy his thing like that?” Yoongi lazily comments, eyeing the old man with a high sort of contempt, satisfaction gleaming, swirling around his dark pupils.

The leader shrugs, “I can’t help it. I amWrath afterall.”

“Yeah, and I’m Lust that’s why I wanted to fuck him so bad, hyung, “ Jimin rolls his eyes, huffing at the ruined state of his brand new Guccis.

Hoseok prods the little faux trinkets displayed on the vanity, careful not to step on any broken vases or blood. He frowns at the cheap jewelry and stands to his full height once more. “So how do we explain to our dear little wife where we’ve been because these blood stains aren’t washing themselves, you know?”

“We don’t. She doesn’t need to know anyway,” Jungkook murmurs, glancing at his phone. “Can we make it back by dinner time? She’s cooking steak and I am not missing that for anything because noona is the best cook!”

Seokjin huffs, “Of course she is. I taught her how to after all.” 

Taehyung notices the woman slowly sneaking out and slams a foot to shut the door, alerting all others to her plight. “Oops. “ The blase vocalist drawls, his eyes flickering down to the diamond around her neck and he leans down, fingers lifting the silver chain. “Such a gorgeous necklace that you don’t deserve. You don’t mind if I take it, do you?”

She gulps. “W-who are you people?” She whispers.

They smile grimly.

“Have you heard of the eight sins?”
