Two Sisters and One Man
She had been doing exactly this only moments earlier—pressing her ear to the door, listening carefully to capture the most decisive scenes while her sister was with Ki-chul.
Back then, she had a clear purpose.
So she stood in front of the door, holding her breath, waiting for the perfect moment.
The sounds she had heard that time.
Ki-chul’s rough breathing.
Her sister’s theatrical moans.
She could tell.
That those moans contained none of her sister’s real pleasure…
But now.
The moans coming from beyond the door were completely different.
“Haaang~ Tae-seok… baby… make me your woman again. Huuung~”
A voice utterly drowned in pleasure, reason completely abandoned.
Not words, but instinct itself.
A cry squeezed from the depths of her throat, the kind that melted the soul.
Sounds that suggested she wouldn’t mind dying right then kept pouring out.
Once she reached climax it would subside for a moment before surging again in an even higher pitch.
Like waves.
Endlessly.
Eun-su knew all too well the sensation of Tae-seok’s body entering her.
It was not a simple “insertion.”
The instant his glans parted her folds and pushed inside, every nerve in her body awakened.
His size.
His thickness.
And his rhythm.
She could imagine exactly when her sister made those sounds.
The sounds that came when every part of her melted into that man.
How good must she be feeling right now…
Knowing that made it almost unbearable to keep listening.
Was it jealousy?
Or… was it longing?
Eun-su pressed her ear even closer.
Inside the room, her sister’s moans continued without pause.
I want… to be in there with them.
Tae-seok laid Eun-jung down on the bed.
Then he looked down at her from above.
He said nothing.
Once again she had carried out his orders in silence.
She had seduced Ki-chul, lured him into the trap, and taken her sister’s husband into her body.
He felt she deserved a proper reward.
And the reward she always wanted was the same.
No fancy techniques were necessary.
No complicated positions, no secret stimulations, no clever touches.
In this moment only one thing was required.
Simply thrusting heavily in and pulling out.
That repetition alone was enough.
Once inside, drive all the way to the hilt; when withdrawing, do it slowly…
It was so simple, yet something no one else could manage.
Against Eun-jung’s tightly gripping pussy, he was certain he was the only one capable of this.
“Tae-seok… it feels so good. Haang~”
“I feel so good too. Your pussy is squeezing me so perfectly, Eun-jung.”
“My filthy pussy… feels like it’s being cleansed. Baby… haang~♡”
The motion continued for a long time, and during it Eun-jung had already reached orgasm twice.
And now.
She was racing toward her third climax.
His cock had not left her pussy even once.
It remained inside her the entire time.
Growing hotter and stickier within her.
“Tae-seok… I… I’m going to lose my mind again…”
Eun-jung’s voice already hovered on the edge between moan and sob.
She wrapped her arms around his neck.
Pulled him with all her strength.
His sweat-slick chest pressed against her breasts and she closed her eyes.
She felt his every movement with her entire body.
“Baby… I really feel like I’m going to die. It feels so good I could die… haang…!”
Eun-jung’s moans flowed out without rest.
Her hips never stopped rocking to meet his thrusts.

Tae-seok looked down at her.
The reward was not over yet.
He intended to love her all night long.
Tae-seok spread her legs wider and pressed his pelvis even deeper against her.
Every time he moved, the bed frame creaked.
That sound spread wetly through the room.
At some point, a strange noise from outside the door began to grate on him.
A very small sound.
Like someone failing to hold their breath.
A shallow inhale.
And the faint rustle of clothing brushing the floor.
A sound so quiet it would go unnoticed unless you were listening for it.
He had known from the beginning.
But he had chosen not to acknowledge it.
He had assumed she would eventually leave.
Yet even now, hours later, while he was still inside Eun-jung, that presence had not disappeared.
Emotion Level: 49
Dominance: 54
Even after it faded from view, if the distance was close enough the status window would appear like this.
Tae-seok looked at Eun-jung.
She still had her eyes closed, body surrendered to his movements.
The moans slipping between her lips.
Her flushed cheeks.
Her disheveled hair.
Every detail was lewdly beautiful.
He opened his mouth.
“Looks like Eun-su wants to join us.”
His voice was low but clear. It would surely have reached outside the door.
Eun-jung’s eyes snapped open.
Her body stiffened for a moment.
The pressure of her pussy around his cock weakened briefly, then clamped down even harder.
The moment she understood his words, she seemed only more aroused.
“Eun-su… is outside right now?”
Eun-jung’s voice trembled.
It held more tension than shock, and within that tension bloomed a strange pleasure.
“Yeah. Right in front of the door. She’s been listening to us since the beginning… without moving.”
Tae-seok whispered the words against her ear.
The tip of his tongue lightly grazed her earlobe.
Eun-jung stared into Tae-seok’s eyes.
“What should we do?”
Her pussy continued to squeeze and massage his cock.
“She can’t bring herself to leave.”
His voice remained low.
But it was perfectly clear—perhaps even loud enough to carry through the door.
Eun-jung caught her breath and spoke.
His movements made her words break at times.
“Well… Eun-su must have been hurting too. Even though he’s still her husband… she saw him sleeping with me…”
Her voice mixed pity with a complicated emotion hidden inside it.
Guilt that her sister was suffering because of her.
“What do you want to do?”
Tae-seok asked.
His fingers gave her nipple a light pinch.
Eun-jung thought for a moment.
Then she spoke slowly.
“You… go to Eun-su’s room and comfort her. I’ve… had enough.”
Her words carried concession.
“Are you sure that’s okay?”
Tae-seok asked again, more seriously this time.
“Yes… wanting more would be greedy. But… are you all right? You seem to have pushed yourself already…”
Eun-jung gave a small smile.
It was bitter, carrying a hint of resignation.
Yet her fingers still refused to release his back.
Tae-seok stayed silent for a moment.
Then he spoke slowly.
“Or…”
“Or?”
She echoed, voice trembling thinly.
“Should I call Eun-su in here?”
The instant the words left his mouth, Eun-jung’s body stiffened.
Her pussy squeezed his cock even tighter.
From tension or excitement?
“What? Baby… you can’t mean…”
Eun-jung’s voice rose then dropped again.
She searched his eyes, trying to tell whether he was joking or serious.
“I do.”
Tae-seok’s answer was short.
Eun-jung fell silent.
All sorts of thoughts raced through her mind.
With her sister?
On the same bed?
Sharing the same man?
Just imagining it made her body burn.
Her pussy tightened again.
It was reacting to the fantasy alone.
“Have you ever done anything like that?”
“No… it would be my first time. What about you?”
“Of course I’ve never done it either… It seems embarrassing…”
“So… you don’t want to? If you don’t like the idea, I won’t do it.”
Eun-jung seemed to consider it briefly before answering.
“If that’s what you want… then do it.”
Her decision had not taken long.
It seemed she would rather have them together where she could see than leave them alone somewhere she could not.
“Good.”
Tae-seok gave a short reply as if confirming her consent.
Then, slowly—very slowly—he withdrew his cock from her pussy.
The moment he left her, Eun-jung’s body trembled with longing.
Tae-seok rose from the bed and walked to the door.
He opened it.
Eun-su, who had been leaning against it, nearly lost her balance and fell.
It seemed she had been sitting with her back against the door, knees drawn up.
Tae-seok caught her before she could collapse.
Embarrassed by the position he had found her in, Eun-su turned her face away.
“I’m sorry… I didn’t mean to eavesdrop…”
Her voice, held in Tae-seok’s arms, trembled thinly.
She could not lift her face from his chest.
The tips of her ears burned bright red.
How long she had been there.
How much she had heard.
Tae-seok did not ask.
Her status window told him everything.
Emotion Level: 50
Dominance: 54
He lifted her in his arms and slowly carried her toward the bed.
Her legs, numb from crouching so long, wobbled slightly before steadying in his embrace.
“Sister can join us too.”
Tae-seok’s words were perfectly natural.
Eun-su’s eyes widened.
“Are you insane… what are you saying?”
Her voice rose, but it held more bewilderment than anger.
And within that bewilderment, another emotion flickered.
Fear? No. Anticipation?
Her body stiffened slightly in his arms.
But she did not push him away.
“Eun-jung says she’s satisfied, so she told me to comfort you now… but I don’t think I can do only that…”
He brought up the fact that Eun-jung had given permission first.
“No matter what… how could I do it together with my sister…”
Eun-su’s voice grew smaller and smaller.
She turned to look at Eun-jung on the bed.
“Eun-su… I’m really fine with it.”
Tae-seok wrapped an arm around her waist and cupped her breast.
“Haaung~”
Her body, already burning from listening to their moans, exploded at his single touch.
And her dominance had already broken past 54.
It was lower than Eun-jung’s, but still a very high figure.
Eun-su bit her lip.
“Sister… are you truly okay with this?”
She asked again in a tiny, crawling voice.
It was already an acceptance of the situation.
Eun-jung looked at her with gentle eyes and answered.
“Yes… I’m fine.”
At those words Eun-su’s heart sank heavily.
She read everything in that answer.
There was no trace of possessive obsession in Eun-jung’s voice.
Instead it carried the relaxed composure of someone saying, Yes, you can have him now. I’ve enjoyed plenty.
Like the casual tone of a person with so many treasures that lending an expensive designer bag to a friend meant nothing.
Eun-su felt a sharp sense of alienation at the sight.
It was utterly different from her own state—unable to leave the spot while imagining Tae-seok embracing her outside the door.
Eun-su thought to herself.
Where does that composure come from? In such a short time… just how many times did she come?
Just imagining it made her burn with envy.
At that moment Tae-seok quietly guided Eun-su to the edge of the bed.
The instant her hips touched the sheets, the soft fabric embraced her skin.
“Sister says she’s okay with it. Come here, sis.”
“Yeah… I feel sorry toward you too… no matter the reason… I slept with your husband after all.”
