Chapter 393 (Shin-bi)

(Se-young)
Squelch, squelch, squelch, squelch!
Si-woo adjusted the speed of his waist, keeping a close eye on Noona’s condition.
As he gradually increased the pace of his thrusts, he tightened his grip around her neck.
"Hag-ugh... Hag-uuugh! Hauuuugh... Hauuuugh..."
Pinned beneath Si-woo’s weight and choked by his hand, Shin-bi Noona reached a point where she couldn't even breathe properly.
Unlike Se-hee Noona, Shin-bi Noona had always treated Si-woo with a warm, gentle smile. Perhaps Si-woo had harbored a sense of admiration or a fluttering heart for her because of that.
Now, Si-woo was pressing her down in a position that felt like he was ironing her flat, plunging his penis into her as if trying to push her to her absolute limit.
He had wedged his penis deep into her vaginal opening, ruthlessly ravaging her as he swung his hips violently.
As Si-woo became acutely aware of this reality, a surge of peak pleasure welled up from deep within his gut.
Thwack! Thwack! Thwack! Thwack!
With the greatest strength and speed he could muster, Si-woo hammered into Shin-bi Noona’s pussy hole.
—As if he intended to shatter her pelvis from behind...—
Her smooth yet textured mucous membrane, slick with sweat and pussy fluid, rubbed intensely against Si-woo’s shaft as if it were burning.
"Haug! Haa-ah! Haak... Hauugh!"
Under the force of Si-woo’s powerful pounding, Shin-bi Noona let out groans that sounded as if she were about to lose consciousness.
Even seeing her like that, Si-woo didn't stop. He continued to drive his massive penis in and out of her hole.
At some point, Shin-bi Noona’s waist buckled beneath him, and her upper body arched backward.
"Hauuuuuu... Huguuuuuuugh!! Haaaaaaat!"
With the back of her head pressed against Si-woo’s neck and shoulder, Shin-bi Noona moaned with her eyes rolled back and her mouth agape.
The muscles in her buttocks and thighs were pulled taut with tension.
Her pussy hole tightened around Si-woo’s penis as if it were trying to snap a pillar of solid steel.
The sensation of his penis being squeezed sent a jolt of pleasure through his spinal cord, piercing straight into his brain.
"Aaaah! Shin-bi Noona!!!"
As if finally releasing the unbearable peak of pleasure, Si-woo called out her name and thrust his waist deep inside her one last time.
Splurt! Splurt! Splurt!
Si-woo’s penis exploded deep within Shin-bi Noona’s hole.
Splurt! Splurt! Splurt! Splu-uuurt!
As if determined to vent every last drop of lust into her body, Si-woo focused every nerve on his penis, ejaculating while pinning her down.
"Haguuuugh... Haut... Huguuuuugh!"
As if experiencing a second climax within the first, Shin-bi Noona’s rigid body shuddered and trembled violently.
Si-woo’s mind went completely blank.
"Aaaaaah... Haaaaa..."
An involuntary, pained groan escaped Si-woo’s lips.
—As if he were loath to let the extreme, soaking pleasure drain out of his body...—
For a long while, the ceaseless trembling of Shin-bi Noona’s body was transmitted directly to Si-woo.
Thud!
Shin-bi Noona’s arched upper body went limp, falling back onto the bed along with Si-woo.
It seemed she had fainted the moment she reached her climax.
White froth was bubbling around her slightly parted lips.
Her body continued to twitch and jerk intermittently.
"Haaa... Haaa... Haaa..."
Lying on top of her, Si-woo felt her tremors and spasms as he gasped for air, his breath catching in his throat.
His penis remained buried deep inside Shin-bi Noona’s body.
As the day’s lethargy and exhaustion washed over him all at once, Si-woo’s eyes drifted shut.
How much time had passed?
Si-woo opened his eyes, still lying on top of Shin-bi Noona in the same position he had ejaculated in.
It seemed he had lost consciousness for a moment due to the fatigue that had built up.
Shin-bi Noona was still unconscious, pinned beneath him.
The beads of sweat forming on her flushed skin served as a reminder of the intense act they had just shared.
Si-woo gave her heated body one firm embrace.
Then, propping his arms against the mattress, he pushed himself up.
He pulled his softening penis out of Shin-bi Noona’s hole.
The clinging walls of her vagina rubbed against the sensitive skin of his withdrawing shaft.
The friction between his penis and her vaginal walls, exchanging intense stimulation, caused both of them to twitch once more.
Like a large serpent emerging from a cave, his limp penis slid out of Shin-bi Noona’s hole.
Given its size, a large gap in the shape of his penis remained between the folds of her fissure, only slowly beginning to shrink.
A mixture of red blood and white semen trickled out from between her folds.
Seeing his own semen mingled with Shin-bi Noona’s virgin blood flowing from within the fissure, Si-woo felt an indescribable sense of liberation and euphoria.
The ecstatic sense of achievement from having claimed her seemed to fill his chest to the brim.
The darkness in Se-jin Noona’s room was now completely familiar to Si-woo’s eyes.
He turned his head to check the clock hanging on the wall.
In the darkness, he could easily make out where the hour and minute hands were pointing.
It seemed not much time had passed since he entered the room.
Si-woo lay back down beside Shin-bi Noona.
He took a deep breath, trying to shake off the lingering, uncomfortable remnants of excitement left in his body after ejaculation.
As his mood settled into a calm state, he shed his feelings of agony and doubt, reflecting once more on the conversation he’d had with Shin-bi Noona earlier.
While catching his breath, he began to organize the facts he had learned about the situation and the details he had confirmed with her, one by one in his head.

The mothers of the guys he had seen at the police station were definitely the same people from the photos Aunt Gyu-ri had sent and the entries in the Slave Ledger he had found in Se-jin Noona’s room last night.
Did those guys know that their mothers were in a perverted master-slave relationship with someone?
Among the inheritance clauses in the Slave Contract, there were no specific mentions of male siblings who weren't the designated heirs.
Cheol-jin might be a unique case, but wouldn't a slave normally try to hide truths that didn't need to be told from their children and family?
In any case, the guys at the blind date didn't seem to know anything about what was happening between Si-woo and his family.
While Si-woo felt relieved, he couldn't shake a certain nagging feeling.
According to the contract's provisions, the children of female slaves were to inherit their mother's status and be raised to live as the children of slaves.
Looking at the way So-ra Noona—who had been involved with him in the master bedroom in a way that felt like rape—and Shin-bi Noona—who had just been ravaged and pierced in an overbearing doggy-style position—treated him, he didn't get the impression that they were resisting or felt any repulsion.
If anything, around the time of the blind date, they seemed to be approaching him even more boldly, as if they were actively trying to reveal their identities to him.
Were So-ra Noona and Shin-bi Noona treating Si-woo as their Master that day?
Though a few suspicious points remained, Si-woo felt there was no longer a need to harbor great hostility toward Shin-bi Noona.
Whatever the case, it was Shin-bi Noona who had given him information about the Sex Diet and who had brought him to the blind date as her partner.
—Even if it felt somewhat offensive that she had skipped the detailed context and important explanations because "there was no time" before throwing him into the blind date...—
It was certain that she was treating him with a friendly attitude.
Si-woo reached out and squeezed the buttock of the woman lying face down beside him.
Her luscious backside was something he had unconsciously wanted to grab since the moment he first saw her.
Come to think of it, when was the first time he met Shin-bi Noona?
Among Se-hee Noona’s friends, she was the one he believed he was closest to.
But thinking back, Si-woo actually knew very little about her, despite feeling like he’d known her for a long time.
All he knew was that she was close to Se-hee Noona, that they were in the same track club during their time at the Intermediate Academy... and that she was Seul-gi’s older sister.
He had only recently found out about her aunt, Teacher Yoo Ye-na... and he had no idea who her parents were, where she lived, or what kind of environment she grew up in.
Si-woo suddenly became curious about Shin-bi Noona’s mother, who might very well be listed in the Slave Ledger.
