Chapter 129: Side Story - Younger Sister (12)♥
Right before Shin Ye-ji’s eyes, the siblings began their act of incest. As Kang Yu-ri’s hips moved, she took her brother’s cock inside her with a surprising, lover-like proficiency.
To Shin Ye-ji, the sight was something entirely alien and staggering.
The way that massive thing entered her friend and transformed into such violent motion...
It was a scene so shocking that Ye-ji found it hard to believe.
Perhaps it was because she was inexperienced and had been raised in a rigid, conservative household, but what was unfolding before her was something difficult for anyone to comprehend under normal circumstances.
Her best friend was showing her the secret of her incestuous relationship with her own brother?
It wasn't normal. And yet...
Ye-ji couldn't help but stare, mesmerized, at the union that felt both blasphemous and strangely sacred.
A moan escaped. It was a sound she never imagined her friend could make—a sound beyond the reach of her imagination.
It wasn't crude or animalistic, but a beautiful, clear tone that suited her lovely face. It was an erotic, sweet moan that sent shivers down the spine of even another woman.
Still, it was a moan she never expected from her best friend, Yu-ri.
Gasping out those sounds, Yu-ri thrust her hips. Her movements were filled with a seasoned skill that Ye-ji couldn't fully grasp at a glance.
She lifted her hips and slammed them down. She raised her backside and impaled herself onto the cock.
On the surface, it looked simple, but the reality was different.
Every time her hips bucked, a sticky sound echoed. A mixture of pussy juice and pre-cum leaked from the point of contact, trickling down his testicles.
Ye-ji couldn't see his wrinkled balls clearly from where she stood, but when she cautiously lowered her posture, they came into sharp focus.
The testicles and the shaft were sparsely haired, showing clear signs of grooming, in stark contrast to her completely hairless pussy.
Seeing the fluid flowing all the way down to the root, Ye-ji unconsciously swallowed her saliva.
She should have felt disgusted. The mere thought of wanting to taste her friend’s fluids should have filled her with guilt and self-loathing for doing something so forbidden.
Yet, with her face flushed bright red, Ye-ji couldn't take her eyes off that liquid. The essence that rolled down his balls and dripped onto the bed, disappearing.
Just as she was feeling a sense of regret and failing to understand her own reaction—
"Hngh...!"
Suddenly, Kang Yu-ri’s body trembled. Her thigh muscles visibly constricted, and her pussy hole, which was clamped around the root, gushed out a handful of pussy juice.
That wasn't all. Ye-ji felt something spray directly toward her face and squeezed her eyes shut.
Leaving behind the sound of Kang Yu-ri panting and gasping for hot breath, Ye-ji wiped the liquid from her face with her hand.
It had almost no scent. What about the taste?
As if possessed, she licked the fluid from her fingers. It didn't have much of a taste either, but...
There was a very faint, metallic hint of blood.
When she opened her eyes, Kang Yu-ri, flushed red all the way to her neck, was looking down at her.
"Ah, sorry..."
Her friend spoke with genuine apology. Only then did Ye-ji vaguely realize what the liquid covering her face was.
"I got too excited because I knew you were watching..."
"What... is this...?"
"Shiofuki... squirting?"
Ye-ji blinked at the unfamiliar term. At her innocent expression, Kang Yu-ri smiled.
"You don't know?"
"No..."
"Here... from here."
Yu-ri stopped the rhythmic movement of her hips while still keeping the cock inside her. At her call, Ye-ji moved closer on her knees, and Yu-ri spread her pussy wide for her to see.
"Ngh, haah... here, can you see here...?"
"It's the urethra..."
Though she spoke calmly, Ye-ji was observing with a detached focus amidst an excitement that felt like it would make her lose consciousness.
"Yeah, from here... it comes out when it feels really, really good."
"Is it... urine?"
"No, no. It's a bit different."
Kang Yu-jin was wondering what on earth was going on as he listened to the conversation between his sister and her friend, but the dialogue itself was arousing, so he stayed quiet and waited with his member still buried inside.
He felt his sister’s pussy, which was now hiked up high to take his huge cock to the very hilt, and he felt her vaginal walls twitching and tightening as she explained.
All of it was stimulating. The fact that his sister was getting excited while explaining this, and that Shin Ye-ji was listening to the conversation as if spellbound.
So, Kang Yu-jin waited for a moment, savoring every inch of his sister’s pussy meat, before speaking.
"Then, I'm going to keep going, okay?"
Kang Yu-ri’s eyes widened mid-sentence, but Kang Yu-jin didn't wait any longer.
In fact, he moved his hips as if the middle of her sentence was the perfect timing.
He placed his hands on both of Yu-ri’s thighs and thrust upward. As his glans crushed her uterus and grazed the very end of her vaginal walls, Yu-ri let out a sharp, high-pitched cry as her back arched flexibly.
"Ngh, ah, Oppa, wait, I...!"
Ignoring his sister’s desperate plea, Kang Yu-jin surrendered to the desire driving his body.
He used the fact that Shin Ye-ji was watching—watching him rapidly violate her best friend’s pussy right in front of her—as lubricant and fuel.
Kang Yu-jin moved his hips with a rough, fast, and practiced snapping motion.
He pressed his backside down deep until he felt the mattress sink, then thrust upward. Every time he felt his glans push against the hard cervix, he would intentionally twist his hips slightly as he pulled out to change the point of stimulation.
Each time, Yu-ri let out a frantic scream, her pussy juice flowing profusely, while Ye-ji looked up at her friend with an expression that mixed worry and fascination.
It was a situation that could only be described as madness, but Kang Yu-jin loved every bit of it.
Part of him wanted to have a threesome with Shin Ye-ji as well, but he couldn't do that given Yu-ri’s obsession and love.
Sometimes, one must uphold love even if it means not getting everything they want. As if reflecting on the love he usually received, Kang Yu-jin suddenly changed his rough movements into something slow and sticky.
At that, Yu-ri began to writhe and sob. The intense, viscous pleasure—the sensation of him scraping against her entire vaginal wall right beneath her belly, frying her brain—actually brought tears to her eyes.
"St-stop... I came, I already came... stop..."
"But Oppa hasn't cum yet."
At those words, at that commanding voice, Yu-ri’s hips flinched. Struggling to keep her torso upright, she panted for breath with her trembling hands on Yu-jin’s knees and her backside raised.
The sound of her whimpering was truly pleasant to his ears. The saying that a man who makes his woman cry isn't a man briefly crossed his mind, but he figured that making her cry like this was essentially the same as making her smile.
Kang Yu-jin shifted his grip and placed his hands on Yu-ri’s waist.
Then, he moved stickily and slowly.
Yu-ri’s reaction to this was fresh. She threw her head back and then dropped it, drooling and shivering. When he pressed against the back wall of her pussy and scraped to the left, she let out a frantic shriek and jerked her head up again.
Kang Yu-jin knew Yu-ri well.
When they first started their relationship, Kang Yu-jin was certainly the one in control.
But that was short-lived. Women tend to adapt quickly, and thanks to Yu-ri’s talent for studying how to maximize her brother’s pleasure, Kang Yu-jin had soon found himself yielding control to his sister.
How much semen had he spent in her mouth, and how much had he pumped powerfully toward his sister’s uterus inside a condom?
Kang Yu-jin knew he couldn't let things stay that way as their relationship continued, so he decided to change himself.
He practiced fencing diligently and trained himself privately.
Furthermore, he spent his days studying and training to become better at having sex with his sister.
In the end, Kang Yu-jin eventually came to overwhelm her.
It had been like this ever since.
When Yu-ri stimulated him, Yu-jin would accept it.
After playing along for a while, once the tyrannical nature sleeping inside him woke up, he would pin her down and use his sister like a masturbation tool or a convenient hole.
While still loving her, of course.
It was behavior that could be called being a tyrant in the bedroom, but both Yu-ri and Yu-jin preferred it that way. As proof, Yu-ri was losing her mind from the repeated orgasms and the pleasure coursing through her entire body, yet she was gripping Yu-jin’s thighs so hard she left nail marks.
Not to push him away, but to hold on. Feeling that stinging sensation anchoring him, Kang Yu-jin paused his movements for a moment. As his panting breath escaped his mouth like steam, he let his sister, whose mascara was smudged with tears, look at her friend.
Though her face was a mess from the pussy juice she had sprayed, the small girl blinked her eyes open and looked up at her friend.
With the two friends looking at each other’s faces, Kang Yu-jin whispered.
"Yu-ri."
No answer came. It seemed she hadn't fully regained her senses yet. When Kang Yu-jin nudged his hips slightly to scrape the vaginal wall, a sob-like "hngh" escaped her, followed by a response.
"Yes, Oppa..."
"You shouldn't spray things like that on your friend."
Wonder filled her eyes as if she didn't understand what he was talking about, but she didn't have the energy to argue.
As Kang Yu-jin skillfully used his glans to scrape from the cervix down the vaginal walls from side to side, Yu-ri couldn't hold back the frantic sounds bursting from her mouth.
When he delved deep into the vaginal walls again from the entrance, her legs lost all strength and wobbled, and Kang Yu-jin had to catch Yu-ri as she collapsed limply onto him.
Because of that, Shin Ye-ji was out of sight, but she was likely listening.
"Is it okay to spray squirting fluid and pussy juice on a friend? Or not?"
"It's... not."
"Then you should apologize."
As he began to move his hips in a squirming motion again, moans leaked out. Holding his sister, who was sobbing and writhing on top of him, Kang Yu-jin thrust into her pussy and urged her to apologize.
"I'm sor-ry, Ye-ji, ahhh...!"
Another climax. Feeling her pussy tightening and pulsing, Kang Yu-jin pressed her.
"Be more specific. What are you sorry for?"
"For spraying... pussy juice... I'm sorry, ahh...!"
"Good girl. That's my girl."
He grabbed his sister’s head, turned it, and met her lips. His sister accepted her brother’s kiss and his tongue as if possessed, her hips twitching. Accepting her spoiled behavior, Kang Yu-jin placed his hand on her lower abdomen.
"Then, as a reward, I'll give you a creampie."
The "hee-hee" sound of her breath was close to a laugh. Kissing his sister, who was too exhausted to even smile, Kang Yu-jin let his eyes wander.
He saw Shin Ye-ji standing frozen by the bedside, her face beet-red, her face and shirt soaked with pussy juice.
"Ye-ji."
"Ye-yes?"
"Come here and put your hand on this."
Then, with trembling legs and a hesitant hand, Shin Ye-ji approached and placed her hand over Kang Yu-jin’s hand on Yu-ri’s lower belly.
It was a sticky, cautious touch. As if a life might sprout inside at any moment, her touch was excessively careful. Kang Yu-jin intentionally thrust upward hard, making Yu-ri’s body writhe violently.
"I'm cumming now."
Both Ye-ji and Yu-ri sucked in a breath. Looking at the two women who were holding their breath, Kang Yu-jin gripped Yu-ri’s thighs tight, pushed his cock as close to her belly skin as possible rather than the uterus, and released the semen he had held back to the limit from his urethra.
A creampie with almost no sound, omen, or even sensation. Like most creampies, it would normally be difficult to even feel the foreign sensation or the change.
But because he had held it back to the limit, the powerfully ejected semen faintly reached through the skin of her belly. Shin Ye-ji’s hand flinched and trembled, and Kang Yu-ri also shook with a silent climax, her head thrown back.
As the ejaculation continued, Shin Ye-ji looked down at her friend with a face flushed crimson.
The always confident and mature Kang Yu-ri.
The best friend Shin Ye-ji admired and felt closest to.
That friend was now reaching a climax while being creampied on her own brother’s cock.
When the long ejaculation finally ended and the cock, stained with semen and pussy juice, slid out of the pussy hole...
Shin Ye-ji was staring at Kang Yu-jin with a bright red face.
As if wanting something, as if craving something.
Though Kang Yu-jin wanted to respond to that desire, he shook his head.
"You'll keep this a secret, right?"
The small girl couldn't answer, her hands just twitching. To persuade her, Kang Yu-jin offered one condition.
"I'll let you watch again."
Only then did Shin Ye-ji unconsciously nod her head.
