    -Swish! Swish! Swish!

    Shiwoo moved his pelvis, lightly rubbing his penis, which was lodged inside Sua’s vaginal opening.

    “Haaah! Haaht! Haaaht!

    Sua moaned, seemingly overwhelmed by Shiwoo’s thrusting.

    Sua planted her feet on the floor and maintained an awkward, kneeling stance, accepting Shiwoo’s penis.

    Already, her cervix was touching and being pressed by the glans, Sua’s hole completely filled with Shiwoo’s penis.

    Sua’s vaginal wall, which was enveloping the front of Shiwoo’s penis, continued to release slick, viscous fluid.

    Sua’s lubricant, flowing down the shaft of his penis, thoroughly soaked Shiwoo’s scrotum.

    A damp and slippery sensation felt from his scrotum.

    Shiwoo thought that she was, as expected of Aunt Seonju’s daughter, born with an inherently lewd body.

    Shiwoo supported Sua’s buttocks and was careful not to let his penis be completely shoved into Sua’s hole.

    He was worried that if he allowed her to accept his massive member all at once, the already painful first experience might leave Sua with bad memories for life.

    As if to warm up Sua’s body, Shiwoo was poking at her cervix and scratching the vaginal wall as if caressing it.

    After several tapping motions, Sua’s tense and tightly clenched vaginal interior gradually began to gain elasticity.

    As soon as Shiwoo sensed the energy inside Sua’s vaginal opening with his inserted penis, a surge of sadistic instinct welled up.

    Shiwoo occasionally released the strength in his hand supporting Sua’s buttocks, causing Shiwoo’s penis, which was filling Sua’s body, to be shoved in even deeper.

    He did so using his waist, thrusting his penis deep into Sua’s vaginal opening…

    Each time, Sua braced herself with her awkwardly planted legs, trembling.

    “Sua! Take your feet off the floor and sit properly on my knees!”

    Shiwoo issued a forceful command to Sua.

    Sua tried several times to lift her feet off the floor but failed, perhaps due to the pressure felt in her uterus.

    “O… Oppa… Haaah…”

    Sua made a tearful sound, seemingly distressed by her inability to follow her brother’s command.

    Shiwoo supported Sua’s thighs with both arms, causing Sua’s feet to lift off the floor.

    As Sua’s feet lifted into the air, her pelvis lowered as if pressed down by gravity.

    Shiwoo’s penis shaft was pressed against Sua’s pelvis, resulting in an even deeper insertion.

    The penis shaft, which had been touching Sua’s cervix, pushed upward as if lifting her internal organs.

    “Haaah-ugh!”

    A moan, as if enduring pain, escaped Sua’s lips.

    Sua desperately tried to maintain her balance, grabbing Shiwoo’s arm that was supporting the underside of her thighs with her hands.

    Shiwoo spread Sua’s legs apart and placed them on his knees.

    Each time Shiwoo gradually released the strength in his arms, Sua’s thighs, resting on Shiwoo’s knees, trembled with exertion.

    Sua’s thigh tremors were transmitted like vibrations to Shiwoo’s penis, which was more than halfway jammed tightly into Sua’s hole.

    After repeating that several times, Shiwoo confirmed that Sua’s vaginal interior had become soft like tenderized meat.

    Shiwoo completely released the strength in his hands that had been supporting the underside of Sua’s thighs.

    Sua was precariously balancing, supported by the legs placed on Shiwoo’s knees, the hands grabbing Shiwoo’s arm, and Shiwoo’s penis fitted into her vaginal opening.

    “Heeeuuuhng~ Haaeeuuuh…”

    Sua let out a moaning sound, as if she was ailing.

    Shiwoo wrapped his arms around Sua’s slender waist.

    He was now intending to begin the piston movement in earnest.

    Sua’s body was trembling, as if foreseeing a storm.

    As if realizing Shiwoo’s intention in wrapping his arms around her waist, Sua tilted her head back and rested it on Shiwoo’s shoulder.

    Sua waited for Shiwoo’s disposal, with her eyes tightly shut.

    Sua’s pleasant, sweat-tinged odor, filled with heat and excitement, reached Shiwoo’s nostrils.

    **

    Just before starting a vigorous pounding session with Sua, Shiwoo glanced at Seyeong, who was sitting across from him.

    The vibrator was still emitting vibrations from Seyeong’s crotch.

    Seyeong was filming the act of intercourse between the two cousins on her smartphone, as per Shiwoo’s order.

    Seyeong was focused on filming, with a slightly distorted, flushed face, as if enduring the pleasure resonating from her core.

    The moment Shiwoo shifted his gaze to Seyeong, their eyes met for a moment.

    Seyeong’s alluring gaze intertwined.

    The sharp and dizzying sensation of pleasure felt as if it was slicing through Shiwoo’s brain.

    Shiwoo briefly released the hands that had been wrapped around Sua’s waist.

    Instantly, the tension in Sua’s body, which had been fully tense, was also released.

    Sua opened her eyes with a look of bewilderment and looked up at Shiwoo.

    “Just a moment!”

    Shiwoo said to Sua as if asking for understanding, then checked the smartphone he was holding in his hand.

    Then, he increased the intensity of the vibrator that Seyeong was wearing to above medium strength using the smartphone.

    The smartphone that Seyeong was holding shook from side to side in time with the increasing vibrations.

    “Hwaaht! Heeueht! Heeueht!”

    Seyeong’s moans were expelled as she cringed.

    A flood of fluids overflowed from between her twisted thighs.

    The fluids dripped down Seyeong’s calves to her ankles, soaking the orange casual socks she was wearing.

    The color of the kangaroo drawn on the socks gradually darkened as it got wet.

    Due to Seyeong’s moans and the stimulation visible before his eyes, Shiwoo’s penis swelled even more inside Sua’s hole.

    Shiwoo switched the smartphone’s screen to the camera app screen.

    Then, he pointed the lens at Seyeong and touched the video recording button.

    -Tteoling!

    Two siblings filming each other’s lewd appearances.

    What would Mom think if she saw the videos that Shiwoo and Seyeong were simultaneously filming of each other later?

    Imagining his mom’s feelings, Shiwoo’s penis grew larger again inside Sua’s vaginal opening.

    Sua showed a reaction of stiffening her body to Shiwoo’s enlarged penis.

    Shiwoo pressed the stop recording button and put the smartphone down next to him.

    Then, he wrapped his arms around Sua’s waist again and began to shake his hips without giving Sua any time to prepare.

    -Swuck! Thwack! Thwack! Thwack! Thwack!

    Shiwoo thrust his pelvis forward, piercing Sua’s hole.

    “Haeung! Haaahng! Haaht! Haeuck! Haaht”

    Sua’s body, surprised by Shiwoo’s sudden thrusting, lifted upward and her back arched backward.

    Sua tried to gather her thighs inward and give strength to them strongly, trying to escape from Shiwoo’s arms.

    An effort to somehow alleviate the impact of the deeply shoved-in penis.

    But Shiwoo’s arms were firmly fixing Sua’s pelvis and waist.

    Moreover, she soon realized that it was difficult to exert enough force to escape with her legs hanging in the air, placed on Shiwoo’s knees.

    Sua struggled for a while, then let go of her strength as if she had given up, and leaned her upper body against Shiwoo’s body with her body drooping.

    Then, each time she felt the stimulation of the penis piercing and pressing deep inside her vaginal opening, Sua startled and lifted her body again as if surprised.

    Without her will, her thighs were once again tensed as if stiffened.

    Her thighs were clamped as if constricted inwards, and Sua’s back was tautly arched backward.

    Sua was pushing down Shiwoo’s arms wrapped around her waist with an expression that was indistinguishable between a crying face and a face intoxicated with bliss.

    Pain that pierced through the center and pleasure that seemed to melt the entire body were clinging to Sua tenaciously, tormenting her.

    Shiwoo pulled his penis back and then examined Sua’s trembling state.

    “Haaaah… Haeeuuht… Haaaah~”

    Rough breathing and a vacant expression as if her mind had left her.

    He could read a desire in Sua’s eyes that she was hoping it would end like this.

    Shiwoo’s sadistic instinct was strongly stimulated.

    Shiwoo moved one of the hands that had been wrapped around Sua’s waist towards Sua’s chest.

    Shiwoo’s lewd hand slid up as if sweeping across her stomach over Sua’s clothes.

    Shiwoo’s hand covered Sua’s left breast.

    The soft and tender breast came into Shiwoo’s hand.

    Shiwoo was seemingly entangling Sua’s body by wrapping both arms around her torso.

    Sua’s body, firmly fixed in Shiwoo’s arms, seemed to have no room to move any further.

    Like a beast’s method of completely blocking movement just before severing the breath of a hunted prey, Shiwoo’s hands were intertwined zigzaggingly on her body.

    “I won’t stop until you come.”

    Shiwoo said in a low whisper into Sua’s ear, who was completely trapped in his arms with her core pierced through.

    “Haeheueeuu… Heueueeuht… Haeheueueeu…”

    Sua, hearing Shiwoo’s low whisper, moaned as if sobbing and trembled.

    Shiwoo tried to soothe Sua by fondling Sua’s breast held in his hand.

    Sua’s glutinous rice cake-like breast was being crushed and deformed in Shiwoo’s hand.

    “Haaaah… Haaaah… Haeheueueeu….”

    Sua’s breath was weakly exhaled as if it was strenuous.

    -Ssihpuck! Ssihpuck! Ssiheo-uck!!

    Shiwoo did not give her any more leeway and thrust his penis into Sua’s vaginal opening as if penetrating her body as is.
