Chapter 270

Si-woo lay sprawled over his unconscious mother's body, savoring the afterglow of his ejaculation for a long while.
With his softening penis still buried inside her, he took a moment to catch his breath, idly kneading his mother’s breasts.
As the lingering heat of his passionate release faded and his mind began to settle, his smartphone, lying on the bed, caught his eye.
It was the phone he had tossed aside just before he began his heavy thrusting into her.
Still lying there, Si-woo let go of her breast and reached out to grab the device.
The chat window with Se-young was still open on the screen.
Small thumbnails of the mothers' lewd orgy photos were lined up in the chat.
Naturally, the number next to the photos he had sent had not disappeared.
Se-young was currently asleep on the second floor, naked and still latched onto Se-hee Noona’s breast.
It wouldn't be until tomorrow morning or even later that Se-young would check her phone and see the photos he had sent.
It was a given that if he left them there, Se-young would see these obscene images of her mother.
In the heat of sex, Si-woo had texted Se-young those lewd photos from his mother's past.
He had even gone as far as showing his mother the confirmation that they were sent, right before her eyes.
While he had certainly sent them to expose her and provoke her, the truth was that Si-woo hadn't actually intended for Se-young to see her mother's depraved past.
He had figured he could simply delete the photos from the chat window before Se-young ever checked her phone.
Si-woo began reviewing the photos in the chat one by one.
Pregnant women in veils engaged in a lesbian orgy.
He started deleting the photos in order, starting from the top.
But his hand paused just before he could delete the last one.
It was a photo of his mother lying down with her mouth open toward the camera, filled with Si-woo’s semen.
If Se-young actually saw this photo of her mother in such a debased state...
The image of a flustered Se-young seeing the photo flashed through his mind.
As that sinful scenario took shape in his head, Si-woo’s penis, which had withered inside his mother’s body, began to surge with power once again.
His mother’s body flinched as if reacting to the movement of his cock.
Though she was unconscious, her sensitized body was still responding to the stimulation in her groin.
When he first sent the photos to Se-young, the sense of depravity and reality had felt somewhat distant because he knew he was going to delete them anyway.
But what would really happen if he didn't delete this one and just left it there?
Would Se-young realize that the fluid in her mother's mouth was his semen?
Perhaps Se-young had only been pretending to sleep while he and her mother were together...
A forbidden sense of guilt began to crawl up into Si-woo’s chest.
He felt like savoring that forbidden guilt, along with the pleasure it brought, just a little longer.
It seemed he intended to leave the photo there until the very last possible second.
Si-woo minimized the chat window, leaving that single photo behind.
* * *
After closing the chat, Si-woo opened a recording app on his screen.
It was an audio file that had been recording since the moment he first inserted his penis into his mother.
Si-woo saved the file under the name 'Seon-mi's Moans.'
He hesitated for a moment, wondering if he should upload it to the group chat with Aunt Seon-ju and Se-hee Noona.
After a brief thought, he uploaded the file to his 1:1 chat room with Se-hee Noona instead of the group chat.
He wanted Se-hee Noona to understand exactly how the relationship between him and their mother was evolving...
Though Si-woo was systematically establishing master-slave sexual relationships with the women of the house—including his mother, Aunt Seon-ju, and Se-hee Noona—he felt a particularly special bond with Se-hee Noona.
Was it because he considered her the only person he could share these confusing secrets and emotions with?
When he sent lewd videos or photos of the family to Se-hee Noona, it didn't feel like he was exposing a secret, but rather like he was sharing it.
The mere fact that he could share the family's heavy secrets with Se-hee Noona alone gave Si-woo a great sense of relief.
He believed Se-hee Noona felt the same way.
The immense relief they gained seemed to significantly influence how they accepted each new secret they discovered.
Even after learning the secrets of his mother and the rest of the family...
Even while treating his mother and Aunt Seon-ju as slaves...
Si-woo was now about to let Se-hee Noona hear the high-pitched moans their mother had made.
The voice of a mother who had accepted Si-woo as her master and her husband.
A surge of excitement, coupled with that sense of relief, made his member swell once more.
Si-woo’s penis began to expand inside his mother’s pussy hole.
He slowly moved his hips, creating friction inside his unconscious mother.
As if to reconfirm the twisted family dynamic that had now reached a point of no return,
—Squelch! Squelch! Squelch!
A dizzying sensation, like tearing through the fissures of reality, wrapped around his sensitive, post-orgasmic penis.
Even in her faint, his mother’s body reacted without fail, bouncing with every thrust.
—Squelch! Squelch!!
Si-woo ground his hips a couple more times, pinning down her twitching body.
Then, as if the sensitive stimulation was becoming too intense to bear, he abruptly pulled his penis out of her pussy hole.
Si-woo’s semi-erect penis was covered by a condom filled with semen.
He carefully peeled the condom off the shaft of his cock.
He wiped the fluids clinging to his penis onto his mother’s arms and breasts.
Then, without a hint of hesitation, he turned the used condom over and brought it toward his mother’s face.
As if performing a sacred ritual, he squeezed the semen from the condom onto his unconscious mother’s face.
The semen that had filled the condom spilled out, staining her lips and the skin around her mouth.
Si-woo placed the emptied condom on top of her breast.
He looked down at her, admiring the sight.
Se-young’s panties covering her eyes.
The red leather dog collar and leash around her neck.
The used condom resting on her breast.
The deep bite mark he had left near one of her nipples.
And the various fluids staining her body.
Between her soaking wet thighs, her juices were still overflowing.
She looked utterly depraved.
Yet, Si-woo felt like something was still missing.
He glanced around the room.
He found what he was looking for on his mother’s vanity.
It was her lipstick.
Si-woo immediately walked over to the vanity and inspected the lipsticks on display.
Several tubes were lined up, engraved with the interlocking gold YSL logo.
He picked out a red one he liked and returned to the bed.
Si-woo positioned himself between his mother’s spread legs.
He uncapped the lipstick and twisted the base to prepare it.
He pressed the lipstick against his mother’s belly and began to write.
'Son's Exclusive Whore Pussy'
After combining those provocative words, he drew an arrow pointing toward her genitals.
Then, he spread her legs even wider and wrote on her inner thigh as if signing his name.
'S W Y'
He etched the English letters one by one into her thigh.
In the exact same spot where Se-hee Noona had her tattoo.
Having done that, Si-woo added more words to the clear skin of her front thigh.
'Don't wipe this off; stay like this all day tomorrow!'
Si-woo grabbed his smartphone and stood up from the bed.
Click! Click! Click!
He took photos, capturing every detail of his mother’s lewd state.
He immediately shared the photos of his mother with Se-hee Noona.
Looking at the images of his mother on the screen, Si-woo felt a chilling sense of conquest and euphoria.
His member became fully erect once again.
However, the fatigue that had been building up since the previous day made further sex seem impossible.
Si-woo pulled the blanket over his mother’s stomach as she lay there unconscious.
Leaving her like that, he gripped his smartphone and walked out of the master bedroom.
* * *
The sound of quiet nighttime breathing filled the living room of Si-woo’s house.
His discarded clothes lay scattered right in front of the master bedroom door.
He was about to walk past them since he didn't feel the need to dress right now, but he stopped as if something had occurred to him.
Si-woo picked up his pants.
He reached in and pulled out the key he had kept in the pocket.
The very key Se-hee Noona had given him without explanation.
Si-woo stared at the key in his hand, hesitating for a moment, before moving forward with newfound resolve.
Si-woo was heading toward Se-jin Noona’s room.
