Chapter 124: Side Story - Younger Sister (7)♥
Chapter 124: Side Story - Younger Sister (7)♥
Kang Yu-ri gripped the backrest of the toilet. It was sturdy enough, but it wasn't bolted down firmly.
She realized this the moment her brother’s presence, digging deep inside her, began to sway and rhythmically thrust.
Clatter, clatter. Even as the stall rattled, Yu-ri felt her brother’s familiar weight filling her completely, hammering against her cervix.
Perhaps it was because she had been teased, heated up, and caressed throughout the entire movie.
Even though he had forced himself in somewhat roughly and started moving at a frantic pace, there was no pain. Her pussy, now perfectly molded to her brother’s shape, twitched and squeezed his cock, making wet, squelching sounds.
How many times had they done this? She reminisced about the first time they had shared each other, and how she had explored his body and surrendered her own to him ever since.
Her memories were fragmented, scattering dizzily to the floor with every labored breath as his cock familiarly struck her womb.
The essence of her arousal, memories, and the past were all blended into a thick, viscous fluid. It was a stickiness born from Yu-ri’s deep, obsessive affection.
That very stickiness only made her hips move faster, driving her brother, Kang Yu-jin, to thrust with animalistic intensity.
“Ngh, ah, h-ha… Oppa…”
The words escaped her lips before she could stop them. Without even remembering what she had intended to say, Yu-ri simply fawned over the love her brother was pouring into her, gasping for air.
Sex with her brother was familiar. They had done it so often that it couldn't be anything else.
They did it secretly at home, whenever they were left alone without the family knowing.
Sometimes, they even did it while everyone was in the house.
The bathroom, Kang Yu-jin’s bedroom, Kang Yu-ri’s bedroom.
They didn't care where it was; as long as it was secluded or a place where they wouldn't get caught, they did it.
As a result, Yu-ri thought she had become completely accustomed to this act. At least, until this very moment.
‘Ah, I’m going to come. I’m coming.’
She tried to speak, but all that came out were wanton whimpers and moans. Her reason was slowly fading, and her vision was blurred by tears and overwhelming pleasure.
All she could see were the beige tiles of the wall. Even though she knew this was a public place—a men’s restroom, no less—and that her moans would surely cause trouble, she couldn't stop them from spilling out.
She couldn't hold it back.
The fact that she was doing this with her brother, the fact that he was risking his life to fuck her.
The circumstance that her friend had almost caught them, and that her friend’s boyfriend was already suspicious.
All of it sent an unbearable surge of excitement through her. It filled her mind with an intensity that paralyzed her thoughts, vibrating through her from her spinal cord to her uterus and down to her legs.
She felt like she was going to collapse. Yet, even as her strength failed, she forced herself to stand.
Every time she felt like falling, her brother’s cock pierced her deep inside, skewering her in place so she couldn't even drop if she wanted to.
Her tongue lolled out, dripping saliva, and her arousal fluids splattered onto the toilet cover and the floor.
As another climax approached, she squeezed her eyes shut, feeling as if they might roll back into her head.
Creak—
The sound of the door opening made her eyes snap wide, and she froze. Even her brother’s cock stopped its movement.
They desperately tried to stifle their ragged breathing. Amidst their hearts pounding as if they might explode, the sounds of people entering the room—busy and cluttered—confirmed that the door opening hadn't been an illusion.
Naturally, the siblings stayed still, sensing the atmosphere. Beyond the door, they could see faint shadows moving back and forth.
Conversations drifted in.
Some were talking about the movie, others were discussing their plans for later.
Some conversations were so random they lacked any context.
But all those voices meant one thing: they were not alone in this space, and if they were caught, things would become very difficult.
And then.
Knock, knock.
Someone knocked on their door. The stalls had filled up instantly, and the sound reached them.
“Someone’s… in here.”
It was a strained response. The sister muffled a moan as the cock inside her twitched, but her brother couldn't afford to worry about that.
He only hoped his squeezed-out words were enough. Fortunately, the person who knocked moved away as the sound of the stall next to them opening was heard.
But their retreat wasn't the end. The restroom was still crowded, and there was no reason for everyone to leave at once. The sound of running water, flushing toilets, and hands being washed filled the air.
In the midst of it, Kang Yu-jin tried to catch his breath and looked at his younger sister.
His own flesh and blood, with her skirt hiked up and her underwear pushed aside, being impaled by his cock.
His biological sister, without a doubt. A sister who even shared a resemblance to his own face.
Kang Yu-jin was having sex with that very sister in a public place. And it was because they had stepped out during a movie, unable to contain their excitement.
They were joined together without a condom or any other form of contraception, simply driven by the raw desire to satisfy their lust.
What would happen if they were caught like this? Kang Yu-jin’s mind automatically drifted toward the worst-case possibilities.
Being caught, having to call for help.
Or somehow, their family being contacted. Being discovered by them.
Being arrested for public indecency, and the horror of everyone finding out they were committing incest.
Being forced to confess, testifying about all the time he had spent with his sister.
His life falling into the abyss.
The mere thought brought a chilling sense of despair and crisis, yet it was accompanied by a thrill and an inexplicable surge of pleasure. At that thought, Kang Yu-jin’s cock throbbed and grew even harder.
“…Ngh.”
The sister felt his cock swell even further inside her and clutched her mouth to stifle a moan.
A dizzying sensation pierced through the siblings. Would anyone notice from that small sound?
It wouldn't be strange if they did. Or if they didn't. Either way, the arousal was undeniable. Following their barely swallowed breaths, the siblings locked eyes.
With her head tilted, the sister looked at her brother with eyes drenched in lust, her gaze itself feeling sticky.
And since the brother she saw looked much the same, their thoughts reached the same conclusion at once.
Squeltch.
A loud, wet sound. A sticky sound. It was a sound too sudden for anyone to immediately identify. But as soon as it echoed, his painfully erect cock twitched, and the sister understood her brother’s intention.
She was so excited, so heated up to the point of losing her mind, that she couldn't bear it.
So, as a younger sister should, she had no choice but to accept her brother’s cock.
Kang Yu-ri wore a faint, hazy smile and began to move her hips.
Silently, she moved with enough pressure to keep her vaginal walls tight. She repeatedly pulled away, forcing her pussy to slide along his cock, and then pressed back down. The act threatened to make lewd, wet noises, but by moving slowly, she kept it silent.
It was an arduous, almost ascetic, slow sex. If it weren't for the fact that this was incest in a public place, she would have long since lost patience and demanded he pound her wildly.
But Kang Yu-jin and Kang Yu-ri were perfectly in sync, moving together as they slowly matched their breathing.
When Kang Yu-jin slowly pulled his hips back, Kang Yu-ri leaned her body on trembling legs as if to draw the cock out.
When the head of his cock caught on her entrance, she squeezed tightly and pushed her hips back while Kang Yu-jin pushed forward.
It felt like a new kind of stimulation she had never experienced before. She had thought her brother had already trained every corner of her insides and that her pussy had been permanently shaped by him.
But it seemed that wasn't entirely the case. As if all her nerves were concentrated inside her, she vividly felt the shape of her brother’s cock while keeping her hand over her mouth to accept him.
‘Slow sex is… good too.’
She had never tried it before; whenever they did it, they were always so consumed by lust that things became rough and fast.
But slow sex had its own unique flavor.
Taking her brother’s cock into her entire being, engraving its shape deep into her body.
That, too, was a wonderful feeling. So, Yu-ri interlaced her fingers with his, gripping his hands even tighter as she moved her hips as if possessed.
Even in this process, a climax was inevitable.
Shhh— a tide of fluids erupted. Yu-ri barely suppressed the urge to let her eyes roll back. She struggled to hold onto her fading consciousness while her hips trembled uncontrollably.
The worry that people were in the restroom and that they might be caught slowly began to fade. Eventually, she became unable to even move her hips.
Another climax. Just as she was looking up at the tidal wave that was about to sweep her away.
Thud— her eyes snapped open at the sound. Only after the sticky sound of her drenched pussy squeezing his cock echoed out did she hear him.
“Everyone’s gone.”
Hearing her brother’s whisper, Yu-ri’s hand was pulled away from her mouth by him.
“Ah, h-ha, ngh, ugh, uuuugh…!”
A lewd, leaking sound escaped her. Her eyes rolled wildly, she couldn't hold back her moans, and the wet, squelching sounds grew loud. As her reason slipped away, she could feel her brother’s cock beginning to thrust into her frantically.
Slow was nice, but fast was better. As always, she loved it when her brother fucked her like a beast, using her body as nothing more than an outlet for his lust.
Feeling her brother’s cock directly against her without the unnecessary barrier of a condom, Kang Yu-ri climaxed over and over again.
Amidst the spurting fluids, her stockings were already soaked, and her feet shook unsteadily, her toes curling and uncurling repeatedly.
She didn't know how many times she had come. And even if someone had walked in, she couldn't have stopped. She could no longer hold back her moans; they came out as a scratchy, laugh-like cry.
It was only natural that her voice would go hoarse. But with both hands pinned by her brother, Yu-ri drooled and let her eyes roll back as she was pounded.
Her uterus, surrendering to the continuous assault, retreated upward and trembled.
Her cervix felt as if it would bruise from the repeated strikes of his hard glans.
Her vaginal walls were stimulated to the point of soreness, feeling as if they would catch fire with every pass.
Yu-ri closed her eyes, tears streaming down her face, and arched her back to press herself firmly against her brother.
It was the moment she let out a piercing cry.
“Ugh…!”
She heard her brother’s voice. A single ray of light amidst all that painfully intense pleasure. Opening her eyes as if saved by his voice, Yu-ri felt a vivid sensation of something foreign rushing inside her.
The semen flowing along her vaginal walls, which had been sensitized by the slow sex, made her come countless more times just by its touch.
Ah, ahh, ah, ugh. The sounds coming from her mouth were primal and obscene. Far from cute or pretty moans, they were her rawest self.
But she couldn't help it. As she felt the semen being sprayed onto her battered cervix and flowing down her walls, she couldn't find it even slightly unpleasant.
It was her brother’s semen. The seed of her brother that she had yearned for ever since she first learned about sex.
Like a broken faucet, her brother’s cum erupted from within him without pause. Feeling the semen continue to pulse out of his urethra, Kang Yu-ri leaned against her brother and convulsed.
Finally, the ejaculation ended, and even as the cock inside her slowly began to shrink.
She couldn't escape the pleasure, nor could she regain her senses.
Trembling like a reed at the mercy of the aftershocks, the siblings stayed joined together in the now-silent restroom, catching their breath.
Amidst the clearly masculine and feminine gasps, the brother spoke first.
“…Shall we go back?”
‘My brother really has no sense of mood.’
The sister thought so, but she agreed. She didn't have the energy to argue anyway.
“Ah, Yu-ri.”
Returning to the theater, Kang Yu-ri smiled at her friend while feeling the semen leaking out of her.
A strange sense of victory, and the mild orgasms delivered by the semen flowing along her painfully stimulated vaginal walls.
It was a pleasant smile, a blend of the fact that she had fully accepted her brother’s lust and that he had indulged in hers as well.
Yu-ri’s friend, Shin Ye-ji, couldn't understand why Yu-ri was smiling so happily.
She probably never would.
Though she felt a sense of familiarity in the strangely fishy scent tickling the tip of her nose, she simply watched her friend take her seat. Even until the movie ended, she couldn't quite place what that smell was.
And perhaps, she never would.
