Chapter 312 (Se-young, Su-a)
"Oh, that’s right! Su-a said if we stop by the amusement park today, she really wants to go to the Haunted House! She said she’s never been inside because she was too scared~"
Se-young spoke, returning to a mundane topic of conversation as if nothing were wrong, continuing to toy with Si-woo in an ordinary atmosphere.
"Oh, r-really? You’ve never been inside?"
Si-woo followed Se-young’s lead, turning toward Su-a and cautiously continuing the conversation.
At the same time, perhaps finding Se-young’s boldness provocative, Si-woo pressed the vibrating smartphone—which was resting against the center of her buttocks—downward with more force.
As if reacting to the phone sliding down the curve of her backside, Se-young’s gluteal muscles twitched and tensed.
"Yeah~ We all went to the amusement park with friends before, and even then, Su-a was the only one who couldn't go in because she was scared! Hehe~"
Despite Si-woo’s blatant molestation, Se-young continued to answer him with a nonchalant smile.
"Ah~ So you’ve been there before? But if you were too scared to go in then, will you be okay today, Su-a?"
Si-woo turned his head toward Su-a to confirm.
Su-a couldn't answer immediately, likely conscious of the vibrator humming in her groin and Si-woo’s hand covering her backside.
"Yeah~ She said she’d be fine today because Si-woo Oppa is with her! Remember when you took Seon-ju into the house earlier? While Su-a and I were waiting outside, we kept talking about all the places we wanted to go at the amusement park today!"
Se-young answered for the silent Su-a.
—Casually dropping the title 'Aunt' and just calling her 'Seon-ju' as if it were the most natural thing...—
"Is that so? ...Then today... we can all... go in together."
Si-woo was slightly flustered, but he tried not to show it as he responded to Se-young.
"Yep! Hehe~!"
Se-young chirped in response, wearing her usual bright, innocent smile.
Even though he was pressing a vibrating smartphone against her buttocks, Se-young carried on the conversation as if it were nothing.
And just as Si-woo had done, she naturally called Aunt Seon-ju by her name in front of Su-a, as if the aunt were her subordinate.
Despite her cousin treating her mother with such blatant disregard, Su-a kept her head down and remained silent.
Watching Su-a, a turbulent and precarious sense of transgression spread through Si-woo’s entire body.
A dizzying sensation seemed to strike the back of his head with a delayed ring.
In that moment, it felt as if the veil separating him from his younger sisters had been stripped away instantly, like a mask in a face-changing magic trick.
The thought that no matter what he did now, the girls would accept it while feigning ignorance took hold in Si-woo’s mind with near-certainty.
Si-woo scanned the surroundings and confirmed that the residential street they were walking through in the early afternoon was deserted.
He then pulled his hand away from Se-young’s buttocks and used the edge of his sideways smartphone to hook and lift the hem of her denim dress.
Se-young continued walking, looking straight ahead without a change in expression, as if ignoring what Si-woo was doing to her.
Si-woo slid the hand holding the smartphone directly under Se-young’s lifted skirt.
The sideways smartphone was wedged between Se-young’s thighs, deep inside her skirt.
Si-woo pushed the corner of the vibrating phone up into the crevice between Se-young’s buttocks.
Se-young’s gluteal muscles tensed up again, and this time, it wasn't just her backside—her entire body reacted as if shrinking inward.
"But Se-young, were you okay with the Haunted House? You can’t even sleep alone at night if the lights are off, right? It’ll be pretty dark in there."
Si-woo asked the question with a double meaning to match his bold actions.
"...As long as it’s not... when I’m sleeping... the dark is fine... And since Si-woo Oppa is by my side... I..."
Se-young tried to answer with a smile, pretending to be unfazed again, but she seemed unable to fully control her voice and expression.
As if punishing Se-young’s nonchalant and brazen attitude, Si-woo kept the smartphone pressed firmly against her body in that humiliating manner.
The sensation of pleasure surged through her, vibrating along the space between her legs.
Se-young’s body shuddered periodically as she walked, as if she were hitting peaks of climax.
Each time she did, Si-woo slightly relaxed his grip, loosening the pressure of the smartphone wedged in her buttock cleavage.
Before long, as Se-young’s trembling began to subside, Si-woo applied force to his arm inside her skirt again, slowly sliding the smartphone toward her front mound.
After repeating this process several times, the smartphone between Se-young’s legs was positioned vertically, as if fitted into her long, frontal fissure.
Inside the moisture-filled space of Se-young’s skirt, Si-woo pressed the corner of the smartphone into the gap over her panties.
During the walk, the smartphone had already become soaking wet.
Se-young’s pussy fluid flowed down the phone and onto Si-woo’s hand like fruit juice.
Si-woo then slid his other hand, which had been covering Su-a’s backside, under her skirt as well and began to knead the bare flesh of her buttocks.
Every time he squeezed and twisted her rear, Su-a leaned her body against Si-woo, her face contorting as if in pain.
As much as her face contorted, a slick liquid leaked from Su-a’s groin down her thighs.
That slippery fluid even soaked the tips of Si-woo’s fingers as he gripped her buttocks from below.
He had heard from Aunt Seon-ju that Su-a was wearing a pad inside her panties...
Was the pussy fluid flowing so heavily that it was overflowing the pad?
As expected, the abundance of 'water' seemed to be a trait inherited from her mother’s side.
Si-woo reached his hand into Su-a’s groin to find the source of the leaking moisture.
Along with the sensation of damp fabric, his hand soon brushed against the vibrator.
Though it was supposed to be a weak vibration, the device positioned against Su-a’s clitoris was buzzing so intensely it made Si-woo’s fingertips tingle.
Using his middle and ring fingers, Si-woo pressed the vibrator firmly against Su-a’s body.
—Bzzzzzzzzzt!—
The sound of the vibrator, pressed between his fingers and her pubic bone, grew even louder.
"Haaah... hngh... hmmm~"
Su-a’s body trembled as she let out sounds that were hard to distinguish between moans and heavy breathing.
Just like with Se-young, Si-woo pulled his hand away from Su-a’s groin whenever that happened.
He repeated the process of bringing his hand back once her trembling subsided.
The smartphone wedged in Se-young’s crotch, and the vibrator buzzing against Su-a’s clitoris.
Between the three people who had fallen silent as they walked slowly, heavy vibrations echoed from both sides like a harmony, accompanied by the sound of the mini fan motors.
The ragged breathing of the two sisters seemed to intertwine and flow back and forth.
* * *
The vibrations did not stop until they left the residential area and the large road with passing cars came into view.
As the figures of people began to appear one by one in the distance, Si-woo withdrew his hands from inside Su-a and Se-young’s skirts.
His smartphone was drenched in a slick liquid, as if it had been dropped in water.
With some difficulty, Si-woo manipulated the smartphone screen to stop the vibrator operating inside Su-a’s clothes.
Only after the vibrator stopped did Su-a’s contorted expression relax, and she stepped away from Si-woo to catch her breath.
Beads of feverish sweat had formed on Su-a’s flushed face.
While catching her breath, Su-a glanced at Si-woo and turned off the mini fan hanging around her neck.
—Since, from the beginning, the fan’s purpose hadn't been to cool her down...—
Se-young also stepped away from Si-woo for a moment to straighten her disheveled clothes.
Though not as much as Su-a, Se-young’s cheeks were also flushed as if heat were rising from her body.
Si-woo tried to wipe the sweat from Su-a’s forehead and cheeks with the sleeve of the shirt he was wearing as an outer layer.
Using the sleeve of the arm that had been inside the girls' skirts, Si-woo brushed over Su-a’s forehead to wipe away the beads of sweat.
Su-a stood there dazed, her face red as she caught her breath, surrendering her body to Si-woo’s touch.
Si-woo finished wiping the sweat from Su-a’s cheeks and the bridge of her nose.
Then, he subtly brought the fingers that were stained with Su-a’s pussy fluid to her lips.
Su-a flinched and pulled her head back slightly, as if startled by the slick sensation on her lips.
Su-a knew that the slippery liquid on Si-woo’s fingers was the fluid that had come from her own groin.
And she also knew that the liquid on Si-woo’s other hand was the fluid he had scooped up from under Se-young’s skirt.
