Chapter 119: Side Story - Younger Sister (3) ♥
It hadn't even been a year since Kang Yu-jin and his younger sister started living together, but it had been quite a long time since they had begun their incestuous relationship.
Even before they moved in together, the siblings had been messing around at home every chance they got.
While "messing around" might be a crude way to put it, even his sister would likely agree with the description.
Their relationship had grown so thick and heavy with lust that it wasn't surprising that Yu-jin felt more excitement than anxiety or fear in their current situation.
"Yu-ri..."
"Shh. You'll wake Unnie."
Grinning and reeking of alcohol, his younger sister pressed her body against his. Her pussy, drenched in sticky juices, stained her hot pants and underwear as she ground against him. His cock, already out of his pants, throbbed at the familiar scent and the sensation of her closeness.
"No, I mean, even so..."
"Do you hate it?"
"It's not that I hate it, but..."
"Then it’s fine~"
She dragged out her words playfully, clinging to him. Yu-jin couldn't bring himself to push her away or act like a stern older brother.
It had been a long time since their relationship had crossed that line, and his body was already completely tamed by her.
And that wasn't all.
Yu-jin harbored a subtle, lingering affection for his sister. It was a feeling that made it impossible for him to treat her poorly or even comfortably.
It was the kind of emotion born from the bond of the flesh—the kind he could never speak of proudly or seek advice for.
Nevertheless, the feeling was real. Yu-jin’s body stiffened as he let out a heavy, ragged breath.
"You said you were feeling teased, too, Oppa."
Her whisper was sweet. Yu-jin knew that what he’d said earlier wasn't just an excuse.
He really had been teased. While his sister had been "cleaning" his cock earlier, Yu-jin had actually been thinking about taking things further.
He’d imagined sliding a condom on, burying himself deep inside his own sister’s tight pussy, and gripping those large, firm buttocks.
He’d pictured them tangled together like lovers on this bed, where they had already shared hundreds of trysts.
That had been Yu-jin’s original plan, but the plan had shifted.
Perhaps in an even more exhilarating direction.
Knowing this, Yu-jin groaned at his sister’s touch but didn't push her hands away.
"Let's do it secretly... If we're quiet, Unnie won't know."
Giggling, Yu-ri climbed on top of him. Yu-jin watched as her dolphin shorts, soaked through and damp, slid down with a wet, squelching sound. Her underwear was pushed aside, revealing the familiar pussy beneath.
He realized he was several times more aroused than usual.
Why? Was it because his eldest sister was sleeping right behind them? Because he knew his life would be over the moment she woke up and caught them?
Was it the thrill?
It certainly was. Yu-jin barely managed to swallow a gasp. He squeezed his eyes shut and let out a low moan as the familiar, welcoming vaginal walls enveloped his cock.
Her pussy felt stickier and hotter than usual.
Perhaps because of the alcohol, it felt as if she were melting around him. Even her flowing juices were hot; Yu-jin could vividly feel the trail of nectar running down his shaft.
As those pleasurable walls squeezed him, Yu-jin’s eyes fluttered before suddenly snapping wide open.
"Wait, what about a condom?"
"Hmm?"
"I'm not wearing a condom..."
"Ah."
She let out a soft exclamation as if she’d only just remembered, yet she didn't stop moving her hips.
That sticky, exquisite pussy continued to wrap around him. His sister’s incestuous pussy—a taste he’d known since before she was even an adult—clung to Yu-jin’s cock and refused to let go.
She moved her hips skillfully, sucking and pulling at him with every upward and downward stroke. It was a piercing pleasure that made Yu-jin’s waist tingle instinctively.
When Yu-jin looked down, a moan escaping his lips, his sister gave him a seductive, narrow-eyed smile.
"I don't know."
As if you don't know. Yu-jin looked at her with disbelief, but his sister didn't hesitate.
She leaned her upper body back, her hips rolling in a rhythmic wave. Her smooth belly didn't show it, but within her coexisted a hungry uterus and a pussy perfectly molded to the shape of her brother’s cock.
As if to show off, Kang Yu-ri pulled her shirt up and bit down on the hem. Gripping both of her brother’s thighs, she panted heavily while working her hips.
Her exposed breasts bounced up and down with her movements, and her sweat-beaded skin glowed beautifully.
It was a body she had meticulously cultivated just for her brother, having already remodeled Yu-jin’s tastes to fit her own image.
Knowing this all too well, Yu-jin began to thrust back in time with her movements.
Since he was sitting, it was difficult to move his hips, but his past "training" made it possible, however awkward. Within a few strokes, the mixture of her juices and his pre-cum began to make a wet, squelching noise.
Muffled moans leaked through the T-shirt she held in her mouth. Yu-jin clamped his own mouth shut to stifle his cries. Every time he did, her pussy meat swallowed him to the root and then pulled back, repeatedly milking him for his semen.
This was dangerous. Of course, he knew his sister would take an emergency contraceptive pill afterward.
It happened often. She would intentionally tear a condom or go without one, stimulating him as much as possible to force a creampie.
Then, she would tell him she’d take the pill just to make him feel relieved.
It was a typical Yu-ri prank, but at the same time, it was an act that provided immense stimulation.
Moreover, it was a catalyst that made him realize his own twisted feelings for her. It was the same now. Yu-ri leaned back slightly, letting the head of his cock press against her cervix as she gasped for air.
"...Nngh."
The act itself was intoxicating. The situation, combined with his sister’s pussy—which was more swollen and heated than ever—provided the perfect stimulation.
If not for the voice that suddenly rang out, he would have been too aroused to care about the consequences.
Yu-jin flinched and held his breath at the timely sound of someone tossing and turning behind him. Yu-ri stopped her hips and let go of the T-shirt in her mouth.
The saliva-stained shirt fell back down, providing just enough cover. Yu-ri’s eyes darted around as their eldest sister’s breathing settled back into a steady rhythm.
In a silence that felt like an eternity, the siblings locked eyes.
"...Slowly."
"...Okay."
Yu-ri took a few ragged breaths, glancing at Kang Yu-dam a few times before leaning forward and wrapping her arms around her brother’s neck.
"Then... hold me tight. I think I can go slowly if you do."
Her voice was a sweet whisper. Seeing her act so differently from the lustful, moaning creature of a moment ago, Yu-jin reflexively nodded and wrapped his arms around his sister’s slender waist, pulling her into a hug.
"Mm, hngh, ah, hee..."
Locked in her brother’s embrace, Yu-ri moved her hips slowly.
She felt her brother’s "love" twitching inside her, and she felt her own greedy desire poking at her uterus, begging for more.
She intentionally teased him, slowly repeating the motion of taking him in and letting him out. Despite her ragged breath, she made a conscious effort to suppress her movements.
"Haa, heehee, Oppa..."
Even though she knew her whispered voice was becoming dangerously sweet, Yu-ri didn't try to hide it.
Her mind was flushed with alcohol, and they had grown closer through this chance opportunity.
And finally, she saw the love beginning to flicker in her brother’s eyes.
Yu-ri felt a fresh wave of joy. She moved her hips leisurely, whispering into his ear as she held him.
"Oppa, I love you."
She knew exactly how Yu-jin would react to such a confession. She knew his cock was throbbing inside her as if he were about to blow at any second, and that despite the fear of pregnancy, he was plagued by the urge to knock his sister up.
"Oppa—"
So, she kept her hips moving steadily, and knowing he could no longer hold back the impending climax, she whispered into his ear on purpose.
She wanted to hear him say he loved her as she took his semen into her womb.
She wanted to receive the incestuous cum she was already addicted to deep inside her entire uterus.
However.
"...Mmm, Yu-ri...?"
At the voice that suddenly came from the bed, Yu-ri’s eyes went wide, and she froze.
Whether it was from the sudden shock or the perfectly timed peak of pleasure, she instinctively squeezed her pussy tight.
Whether it was because of that intense squeeze or the sound of their eldest sister’s voice, Yu-jin reached his climax right along with her.
He caught his breath in an instant. Swallowing his gasps, Yu-ri clung to her brother’s neck, trembling as her vision blurred with the intensity of the orgasm.
Ah, Oppa’s cumming too.
Her calm thought was at odds with the violent, overwhelming climax.
Yu-ri felt tears prick her eyes and her head roll back as she squeezed her brother tight.
We're going to get caught. We're going to get caught. But it feels so good. As Yu-ri’s trembling subsided, she felt his cock, which had been filling her to the brim, slowly begin to shrink.
It was such a powerful climax that a bit of her voice had leaked out. The volume of his ejaculation was so great it gave her the illusion that her uterus was being inflated.
Feeling a slight sense of mischievous triumph at that fact, Yu-ri lifted her head.
"What are you doing...?"
"...Just hugging Oppa..."
Would such a pathetic excuse actually work? Yu-ri worried for a moment.
"Yu-ri, do you really love your brother that much...?"
Kang Yu-dam, the eldest sister, simply spoke with a hazy smile, as if she hadn't quite sobered up yet.
"Yeah, I love him so much. Oppa is the best."
"Such a baby..."
Yu-dam pulled the blanket over herself, curling up like a pill bug and exhaling a breath heavy with the scent of alcohol.
"Unnie’s going back to sleep..."
Yu-dam fell back into a deep slumber. Yu-ri watched her for a long time before slowly unwinding her arms from her brother’s neck.
The siblings locked eyes again. Their dark pupils, wet with the pleasure of vivid excitement and the thrill of the risk, searched each other’s eyes in a dizzying whirl of emotion.
In that moment, they both knew.
It wasn't over yet.
As if on cue, the siblings began to move at the same time.
This time, it was as if they didn't care if they were caught.
And unfortunately for her, Kang Yu-dam did not wake up again.
