Moans from My Sister's Room
The moans leaking from her younger sister's room.
“Hey… are you… still okay on stamina?”
Her voice was almost a whisper.
Yet that single sentence carried every ounce of her heart and desire.
Tae-seok instantly recognized her intention from the look in her eyes and the tremor in her breath alone.
But he deliberately pretended not to notice and asked,
“I’ve still got plenty of stamina left. Why?”
Eun-su bit her lip lightly.
Her eyes were moist with shame at having to ask for it first, but her voice was honest.
“I just… I want to become even prettier.”
“That’s why you’ve been working out so hard. You’re already beautiful enough…”
Tae-seok tilted his head slightly and answered with feigned innocence.
“Hey!!! That’s not what I meant.”
Eun-su’s voice suddenly grew loud.
But she quickly covered her mouth as if startled by herself.
“Then what is it?”
“You son of a bitch… you know exactly what I mean… is it fun teasing me?”
“Yeah. It’s pretty fun.”
“Seriously, you…”
She glared at him with angry eyes for a moment before lowering her head again.
“Can’t you just… take care of it without me having to say it?”
“I’m not very smart, so…”
Eun-su shook her head in disbelief.
Should she say it or not?
Dozens of hesitations flashed through her mind.
But the desire burning inside her was too strong to ignore her heated body.
Finally, she spoke in a tiny voice.
“Do it. Hold me… please.”
“You really… want it?”
Tae-seok asked again, as if confirming her answer.
“Yeah…”
“Eun-jung might hear us… is that still okay?”
“I don’t want to get caught… but wouldn’t the chance of that be lower than when we did it on the sofa this morning?”
At the sight of her shy expression, Tae-seok smiled and gently pulled down the blanket.
His cock proudly revealed itself.
Even though it wasn’t fully erect yet, its size and thickness were overwhelming.
“Ha… seriously… you’re insane.”
“Wasn’t this what you wanted?”
“Yeah… it is.”
“Then first… get my cock hard for me.”
It was phrased like a request, but it was clearly a command.
Eun-su took his cock in her hand.
And… slowly moved it up and down.
“Is that all you’re going to do? Can’t you figure it out yourself, Noona?”
At Tae-seok’s words, she shot him a quick glare, but eventually lowered her body as if she had no choice.
She knelt between his thighs, carefully wrapping both hands around his half-hard cock.
The moment the hot, heavy sensation reached her palms, her breathing instantly grew rough.
The cock she had sworn she would never touch—her sister’s man’s cock—only excited her even more the moment she faced it.
She lowered her gaze slightly.
Her long lashes drew thin crescents, casting shadows across her cheeks.
Then she slowly opened her mouth.
Her moist lips parted, and her tongue slipped out.
The tip of her pink tongue first gave the glans a gentle lick.
Slurp…
She wrapped her entire tongue around the shaft and slowly dragged it from bottom to top.
Her tongue circled the most protruding ridge of the glans once.
“Mmm…”
The warm, soft sensation sent pleasure straight through him.
Tae-seok let out a quiet moan between his lips.
His eyes were half-closed, his expression a mix of comfort and tension.
Eun-su opened her mouth wider.
She pushed his cock deep inside.
As the thick, hot object brushed against the roof of her mouth and filled her completely, her cheeks bulged outward.
It looked as if she were holding a small ball in her mouth.
She pressed her tongue against the underside of his shaft and began sucking slowly.
Every time her head moved back and forth, wet slurp, slurp sounds echoed through the room.
Strands of saliva stretched and broke repeatedly.
The heat filling her mouth and the way his cock grew steadily harder made Eun-su’s thighs squeeze together on their own.
She could feel her pussy entrance twitching and pressing against her panties.
It tickled.
“Hah… mm… slurp…”
Target: Kim Eun-su
Emotion Level: 41
She grew more aggressive.
At first she had moved carefully, adjusting the depth, but now she increased her pace.
Every time her head bobbed back and forth, his cock slipped out from between her lips only to be swallowed deep again.
Her saliva flowed down the shaft, glistening under the light.
Eun-su opened her eyes slightly and looked up through her long lashes.
Her gaze met Tae-seok’s.
The sight of her staring up at him with his cock filling her mouth was unbearably arousing.
Tae-seok brushed her hair back with one hand, sweeping the sweat-dampened strands off her forehead.
“It’s hard enough now.”
It was his way of saying she could stop.
But Eun-su wanted to keep sucking.
The feeling that washed over her when she held his thick flesh in her mouth was too good.
Target: Kim Eun-su
Emotion Level: 46
“Just a little longer… I’ll suck a bit more. This is weird… just sucking it feels so good.”
Eun-su’s words were interrupted by the constant wet slurp, slurp sounds.
She refused to let his cock slip from between her lips.
Every time her head moved, her bulging cheeks shifted, and saliva dripped from her chin onto her hot pants.
Tae-seok looked down at her from above.
“Alright. When you’ve had enough, tell me. Then I’ll put it in for you.”
Instead of answering, Eun-su swallowed him even deeper.
All the way to her throat.
Her gag reflex kicked in, but the pressure only transformed into pleasure.
This is weird… it’s really weird… I’m just sucking it and… like this…
“Mmmhh…♡”
A low, long moan escaped from deep in her throat.
Her body trembled violently.
Target: Kim Eun-su
Emotion Level: 50
It was an orgasm.
Even though she thought the situation was ridiculous, the pleasure she felt was real.
Fuck… I came just from sucking cock…
Morning.
The moment Eun-jung opened her eyes, she realized the spot beside her was empty.
The warmth that had lingered there had already cooled.
She reached out and touched the pillow where Tae-seok had lain.
A faint trace of him still remained.
The scent of sweat and the heat of last night.
But he was already gone.
Did Tae-seok… go upstairs?
She tried to sit up and noticed his clothes discarded beside the bed.
His t-shirt and pants were still there.
His clothes are here… so is he naked? No way…
She went out to the kitchen.
No one was there.
Only the low hum of the refrigerator.
She had just finished washing her face in the bathroom when she froze mid-step.
From the direction of the room where Eun-su was staying, a tiny, sweet moan was leaking out.
“…Haa…♡”
Very softly.
Sticky and sweet.
Like honey melting and flowing.
A moan that sounded like it had been desperately held back in the depths of her throat only to fail.
Eun-jung’s body stiffened instantly.
She held her breath and strained her ears.
Again, a low, wet moan slipped through the crack of the door.
“Mmm… Tae-seok… it feels… so good…”
The moment she heard it, Eun-jung’s body began to tremble.
It felt like all strength was draining from her, yet strangely, tension gathered in her thighs.
Her body was reacting before her mind could catch up.
Before she could understand.
Before she could think.
Almost as if drawn by an invisible force, her feet began to move slowly.
In front of the room where Eun-su was staying.
Slap… slap… slap…
The rhythmic sound of flesh slapping together flowed out steadily.
And Eun-su’s lewd moans became even clearer.
“Ah~♡ More… just like that…”
The moment she heard those words, a strange tightness pulled at Eun-jung’s lower belly.
It felt like heat was rising from deep inside her.
“…Why…”
Eun-jung pressed her hand hard over her mouth.
Her eyes widened.
Tae-seok… and… Eun-su?
She couldn’t bring herself to open the door. She simply stood there, listening.
The fact that the man who had held her so passionately all night was now embracing her own little sister pierced her chest like a blade.
A razor-thin, sharp pain spread from the left side of her chest to the right.
Jealousy surged up.
And even stronger than that, a deep sense of loss washed over her.
A hollow emptiness, as if the ground had fallen away beneath her.
But strangely, her anger toward Tae-seok wasn’t that strong.
No, it wasn’t that she wasn’t angry.
But that emotion shrank in comparison to the sense of betrayal toward Eun-su and the heartbreaking thought of why did it have to be my sister?
I did so much… I let him hold me all night… and yet he’s with Eun-su…
Eun-jung tightened her grip on the doorknob.
She wanted to fling the door open and tear the two of them apart.
But in the end, she couldn’t open it.
She simply stood there, listening to her sister’s lewd moans and Tae-seok’s rough breathing.
Every time those sounds reached her, her body grew strangely hotter while her heart grew colder and colder.
Eventually, she whispered so softly it was almost inaudible.
“…I guess there’s no helping it.”
Eun-jung stood in front of the door and murmured quietly.
She slowly and silently moved back toward the kitchen.
The disappointment of why Eun-su? and the self-blame of is it because I’m not enough? tightened her throat.
But soon, the resignation that if he wanted Eun-su, there was nothing she could do came first.
He was already her everything, and she had become a part of him.
I… can’t have Tae-seok all to myself.
The moment she accepted that fact, even as her chest ached, a strange sense of relief seeped in.
As long as he doesn’t abandon me, that’s enough.
If that was the case, there was only one thing she could do.
She had to do better.
She had to become prettier, more obedient, and more eagerly accept his desires.
So that she could give him even stronger, deeper pleasure than what he felt with other women.
She slowly looked down at her own body.
Thanks to their frequent intimacy, her body had already transformed from its old self into that of a seductive and beautiful woman.
“…Tae-seok, I’ll work even harder. I’ll change however you want me to… as much as you want.”
Tears welled slightly in her eyes, but the determination shining within them was far stronger and more tender than before.
It was a quiet yet desperate vow to offer everything she could for Tae-seok.
After bringing Eun-su to climax several times, Tae-seok quietly opened the bedroom door and stepped out.
The clatter of dishes from the kitchen could already be heard.
He knew Eun-jung was awake, but he couldn’t stay in Eun-su’s room forever.
…Even if our relationship gets found out, so what?
Thinking that to himself, he carefully opened the door and stepped into the living room.
He was growing more and more brazen with her.
His power, his choices, his desires.
He no longer felt the need to hide or conceal them.
Tae-seok walked past the kitchen into Eun-jung’s room, put on the clothes he had left there, and straightened his appearance.
With a perfectly casual expression, he came out again and headed toward the kitchen.
Eun-jung was still preparing breakfast as if nothing had happened.
When she turned and saw him, she gave him a gentle smile.
“Tae-seok, you’re up?”
Her voice was as warm and soft as always.
