Beyond the Curtain
Ssshhhk.
The thick velvet curtain drew open with languid deliberation.
Taejun and Arin both swallowed their breath at the same instant.
"Hup…!" "……!"
The spectacle beyond the curtain was far more raw and primal than anything they had dared to imagine.
On the bed, a completely naked Jieun was on all fours, her entire body glazed with sweat, panting like an animal in heat.
Thwack— Thwack—
"Ahhh…! Haaang…! Hnngh…!"

In everyday life she always wore that composed, sophisticated smile—an elegant, self-possessed woman. The creature thrashing before their eyes was someone else entirely.
Jieun’s full breasts swung violently with every impact. Sweat-slick flesh deformed under the man’s rough hands; her pink nipples stood hard and erect. Her narrow waist flared into a lush, round ass; even her thighs gleamed with moisture. Her whole body was saturated with pure lust.
The man gripping her from behind was a towering, thickly muscled brute. Biceps, back, and thighs bulged like a professional athlete’s. Every time his massive cock drove into Jieun’s pussy as if it meant to split her open, her body lurched forward and her heavy breasts bounced wildly.
Slap—! Slap—! Slap—!
With each heavy collision, clear juices streamed down her thighs. Her pussy was already swollen and flushed; every time the man’s shaft pulled free, her inner flesh clung to it and came into view.
“Ugh…! Aaaah…! Deeper… deeper still…!”
Jieun’s eyes were half-rolled back as she moaned. The sounds pouring from her throat no longer belonged to a human being.
"Ghh…! Khhaah…!"
Beast-like, half-strangled cries tore free. Spittle ran from the corner of her mouth; sweat-drenched breasts heaved. Each brutal thrust of the man’s hips shoved her body forward.
Squelch—! Squelch—! Squelch—!
The wet, obscene slap of his pelvis smacking against her plump ass filled the air. He fisted a handful of her hair with one hand, yanking her head back, and crushed his mouth to hers in a savage kiss.
"Mmph—! Chuu—!"
Their tongues tangled frantically; saliva dripped in long strands. Jieun sucked at the man’s tongue as if she meant to devour it, shoving her own deep into his mouth. Even while they kissed, his hips never stopped slamming into her.
“Mmmph…! Mmm…! Kh—! Haah…!”
Kiss and fucking at once left her choking for air. Her eyes had rolled until the whites showed; drool poured down her chin. Her legs trembled violently; her toes were curled tight.

“Haah…! Haa…! So good…! Harder…! Fuck me harder…! Please…!”
Her voice was already cracked and ragged. This shattered, animal state was something the usual Jieun would never have allowed anyone to see.
Her legs spasmed. Her pupils had almost lost focus; saliva kept spilling from her open mouth. The man yanked her hair harder with one hand while the other mauled her heavy breasts as if he meant to burst them. Fingers sank deep, kneading and reshaping the soft flesh at will. Each time her large breasts squashed in his grip and then sprang free, white flesh overflowed between his fingers. He especially pinched and twisted her pink nipples between thumb and forefinger.
“Ahhh…! Haaang…! There…! Yes…!”
Every rough tug on her nipples wrung a raw moan from her throat without the slightest restraint.
Taejun and Arin watched without breathing.
Arin was already trembling, both hands clamped over her face.
“Ah… no… Unnie, no…”
Yet Jieun’s body still leaked through the gaps between her fingers. Arin’s face was scarlet; her thighs had unconsciously pressed together.
Taejun leaned forward, staring blankly. Inside his pants his cock had grown painfully hard, straining against the fabric until every pulse was agony. The image of Jieun howling like a beast, juices pouring out of her, that enormous cock splitting her open—every frame slammed into his brain.
They kept watching.
Then—
Ssshhhk.
The curtain slid shut again. Jieun’s moans, the heavy slap of flesh, everything cut off as if a video had been switched off.
Taejun and Arin both spun, looking around. Their hearts still hammered.
A soft voice rose behind them.
“I’m sorry, but observation ends here. Are you interested in becoming members?”
Lisa approached with a polite smile.
Taejun glanced at Arin for a second, then looked away and answered Lisa in a rush.
“Yes… we want to join.”
Arin, still reeling from the sight of Jieun, could not speak. One hand remained over her mouth; her face burned crimson as she stared blankly at the closed curtain. The memory of her usually calm, elegant unnie howling like an animal, body convulsing, refused to leave her mind.
My graceful unnie… if she can enjoy it that much… then maybe I…?
Whenever Arin had sex with Taejun she felt mostly pain and almost never reached orgasm. Tonight, for the first time, a faint sexual curiosity began to stir inside her.
Taejun called her name.
“Arin…?”
She flinched and answered without thinking.
“…Yeah. Yes… I’ll join…”
Lisa smiled with satisfaction and lifted her radio.
“Escorting the couple to the VIP room. Requesting membership approval.”
She guided them out of the viewing area, down the corridor, and into a VIP suite. The room was furnished like a high-end office—soft lighting, luxurious leather sofas, a wide desk.
Behind that desk sat Elly.
Completely naked.
Her fair skin glowed under the lights. Her breasts were large and firm, pink nipples slightly raised. Her waist was tiny; her legs long and sleek. Most of all, her baekboji was soft, clean-shaven, the delicate pink flesh faintly visible. She sat with her thighs parted a little, yet showed not the slightest hint of shame.

Taejun and Arin froze. Arin flushed and averted her eyes; Taejun had no idea where to look.
Elly spoke in a calm, clear voice.
“Please make yourselves comfortable.”
They took the chairs opposite her. Having a naked woman sitting right in front of them still felt unreal.
“Our club operates strictly through a referral system, and there is no membership fee. Before joining, we thoroughly verify everyone’s occupation, criminal record, and marital status through their identification. So ID is mandatory. You both brought yours, correct?”
Taejun and Arin nodded.
Elly smiled and handed each of them a form.
“This is the Elysium Club Membership Application. Please review the rules listed carefully.”
1. Couple Prohibition Rule
Inside the club, penetrative sex between spouses is strictly forbidden (kissing and fondling also prohibited; observation only is permitted). While members of the club, divorce is absolutely forbidden. (Divorce becomes possible only after formal withdrawal. All events that occurred inside the club are rigorously excluded from divorce grounds; no evidence may be submitted.)
2. Attendance Rule
The club operates twice weekly—Wednesdays and Saturdays—from 7 p.m. until 5 a.m. Couples must attend together. Any inability to attend must be reported to the front desk at least one week in advance. (If unavoidable circumstances force one partner to attend alone, a written explanation is required.) Two consecutive absences incur a no-show fee of 300 points or 300,000 KRW, payable in points or cash.
3. 3P Monopoly Rule
Threesomes (2M1F or 1M2F) are the exclusive privilege of that month’s King. Other members require the King’s permission. (The King may also select the wife.)
4. Contraception & Pregnancy Rule
Internal ejaculation is tacitly prohibited. Condoms, birth-control pills, and emergency contraception are provided free of charge. In the event of pregnancy the club covers all medical expenses (including abortion). Should the child be carried to term, the club pays four years of university tuition. (Paternity testing is absolutely forbidden; the couple is immediately and jointly expelled.)
5. SM Equipment Rule
All toys (vibrators, whips, handcuffs, anal plugs, etc.) must be purchased with rank-up points. Outside items are forbidden.
6. Point System
Basic swap (penetration + one ejaculation): 100 points
3P participation: 300 points
Anal sex: 200 points (male or female)
Internal ejaculation (once): 500 points (male pays the receiving female 100 points)
Swallowing semen: 200 points
Fellatio: 50 points
Public play: 300 points
1 point = 1,000 KRW (cash-out limit 50 million KRW per month)
※ Points may also be purchased with cash.
7. King & Queen Survival
Held monthly. First-place couple receives: 100 million KRW prize, five free 3P monopoly passes, three harem slots, 24-hour private suite access, and a couple’s overseas trip voucher.
8. Top-Four Overseas Location Swap
Once per quarter the top four couples (including King & Queen) are selected for an all-expenses-paid overseas swapping trip. If a couple declines, the invitation passes to the next ranking couple in order.
9. Hell Gate Challenge (Withdrawal Challenge)
Any couple wishing to leave the club must complete this challenge: within 24 hours they must engage in penetrative sex culminating in ejaculation at least once with every male and every female currently enrolled. (Failure means withdrawal is denied; retry possible after three months.)
10. Security Rule
Absolute secrecy regarding everything that occurs inside the club. Violation incurs a 200 million KRW damages claim. All play is video-archived. Upon entry all personal belongings must be surrendered. Phones, recorders, and cameras are banned; possession results in immediate expulsion and a 100 million KRW damages claim.
Taejun and Arin stared at the form for a long time, eyes wide. The system was far more meticulously organized than they had expected.
Elly finished organizing papers and rose from her chair. Every movement made her full white breasts sway gently; the pink nipples quivered just enough to pull Taejun’s gaze back against his will. He tried to look away, only for his eyes to return of their own accord.
Elly asked in that same cool, clear voice,
“You’ve both finished reading, I hope? Do you both wish to join? Even one refusal means membership is impossible. You will also need to sign consent allowing us to verify your marriage through your IDs and family-relation records.”
Taejun and Arin looked at each other. Their eyes said different things, yet a silent negotiation passed between them.
Arin let out a small sigh, then signed with sudden resolve.
Scritch-scritch
Taejun signed immediately after.
Scritch
Elly smiled as she accepted the papers.
“Congratulations. The application is complete. However, before final approval you must both pass a simple test. I’ll escort you to the next room.”
The word “test” made them exchange puzzled glances, then turn back to Elly.
She handed the documents to Lisa for filing, then gave each of them a copy.
“We’ll hold your IDs and return them next time you come. These are your personal copies for later reference.”
Elly led them out of the VIP room and down the corridor to the adjoining chamber.
Click-click, click-click.
As she walked ahead, her naked back—wearing nothing but high heels—captured both their gazes completely. Fair skin gleamed under the lights; her firm, apple-shaped ass swayed gently side to side. Every sharp click of her heels on the floor highlighted the sharp curve of her waist and the long, smooth lines of her legs. The perfect S-curve of her nude body flashed glimpses of her breasts with every step.

Arin blushed and looked away; Taejun’s eyes stayed locked on that provocative backside without conscious thought.
Arin clutched his arm and whispered, voice trembling.
“A test…? What kind of test…?”
Taejun shook his head, face tight with tension.
“I don’t know either…”
They had no idea what that test truly was.
