The Price of the Deal
It was late afternoon, the sun sinking low on the horizon, by the time Kim Seojin finally made it home.
Drenched in sweat as if he had spent hours training under the scorching midsummer sun, he collapsed the instant he stepped into his room.
“Hah… haaah…”
Like a wild animal that had at last reached safe ground, he let out a long, shuddering sigh of relief and leaned back against the door, forcing the boiling heat inside his skull to cool.
His body felt completely drained of strength, as though everything inside him had burned white-hot and left only ashes behind.
I need to wash Mom’s underwear before she gets back…
Seojin thought of the underwear still sitting in his bag.
What had been ordinary laundry when he first took it out was now soaked through with a beast’s filthy lust.
He replayed everything that had happened after they left the restaurant.
Crazy. I must be crazy.
The moment Jung Taeyoung had revealed his lewd desire for Mom’s underwear, Seojin had climbed into the man’s car as if possessed.
Even for an adult man, getting into a complete stranger’s car had been pure foolishness—but he shoved that thought aside and kept turning the memory over in his mind.
Taeyoung had driven them out to the quiet outskirts of the city, parked in a secluded spot, and then boldly demanded Mom’s underwear as if he were simply reclaiming something left in safekeeping.
His attitude had been so utterly confident that Seojin had handed over the prepared underwear without even thinking.
“Ohh…”
The beast’s soft gasp of admiration as he took Mom’s underwear still lingered in Seojin’s ears.
He had sealed Mom’s gray underwear in a plastic zipper bag so the scent wouldn’t escape.
Whether it was simply Taeyoung’s preference or not, the man had insisted so strongly on a gray set that Seojin had been forced to wait until Mom finally wore those exact pieces.
At last, yesterday, Mom had gone to work in underwear that matched Taeyoung’s demand.
This morning, right after pulling them from the laundry basket, Seojin had stood right there and watched a stranger take Mom’s underwear into his hands.
Taeyoung had carefully drawn them from the zipper bag as if retrieving a treasure, then brought them to his nose the way a man might breathe in the scent of someone he loved.
“Sniff… sniff.”
Those soft little sniffing sounds had nearly driven Seojin out of his mind.
Not content with that, Taeyoung had begun sticking the photos of Mom that Seojin had prepared all over the interior of the car.
I almost screamed right then…
They were the photos Seojin himself had uploaded online—Mom in a suit, revealing bathroom selfies, close-up face shots, and more.
Even with the mosaics still in place, the sight of Mom’s photos and underwear held in another man’s hands had sparked a dizzying rush of excitement and corruption that burned straight through his brain.
Before he knew it, Taeyoung was already masturbating with Mom’s underwear.
The shock of watching another man jerk off for the first time had been enormous, but what truly stunned him was the sheer size of the man’s cock.
It was a completely different level of pressure from the photos…
Taeyoung often sent him pictures of his erect dick resting on top of Mom’s photos, but the overwhelming vividness of seeing it in person made Seojin flinch.
That cock, so hard it looked ready to tear straight through Mom’s panties, oozed sticky precum with every throb and steadily soiled the fabric.
Seojin froze, forgetting even to breathe as he watched the gray panties slowly darken from the inside out.
Slick… slick… slick…
Even that wasn’t enough stimulation. Taeyoung wrapped Mom’s bra around the thick shaft of his cock.
It was so massive that any woman impaled on it would probably go weak in the knees and collapse on the spot.
“Ah, aaah…! Ugh, fuck! I’m definitely gonna fuck that bitch!”
Taeyoung suddenly spat out thick curses, freely pouring out his lewd desire toward someone.
Seojin knew without being told exactly who that “bitch” was.
Intoxicated by the sinister, violent aura rolling off the man, Seojin made a single fatal mistake.
“Hey! What’s that bitch’s name? Tell me right now!”
“Ah, aaah…? Y-yes? Th-that is…”
“Hurry up!”
“Ki-Kim So… Kim Soeun…”
The moment he heard Mom’s name, the beast’s lips curled into a dangerous smile, as if he had just been handed the perfect side dish.
“Kim Soeun, huh…! Cute name. I’m definitely gonna fuck your mom… and… kkuuugh!!!”
The weapon hanging from that harmless-looking man swelled in an instant, then began spurting thick, clotted cum.
Gush! Gush! Gush!
Mom’s gray panties and bra were instantly soaked in milky white fluid and turned dark.
Even at a glance, the semen he shot was dense and concentrated—the kind of volume you’d only see in porn—all of it released in a single flood.
It was so thick that if it poured into Mom’s womb on a dangerous day she would get pregnant on the spot; the sticky load thoroughly violated every inch of her underwear.
A fishy night-flower scent filled the car, and the heat of his lewd desire made it hard to breathe.
The intense lust of a stranger for his mother was more than enough to send a cold chill racing down the son’s spine.
“Hooo…”
After he finished, Taeyoung carefully wiped every last drop of cum from his cock using Mom’s underwear, soiling them even further.
Then he stuffed the lust-stained underwear back into the zipper bag, returned them to Seojin, and said in a calm, almost casual voice:
“Thanks for the use.”
Hearing those words made Seojin’s heart drop with a heavy thud.
That bland, offhand way of treating a precious family member as nothing more than a tool for sexual relief.
Even though it was only the underwear that had received his lust this time, it was crystal clear where that desire was truly aimed and whom he had defiled—and that made it all the more chilling.
And in exchange for offering up Mom’s underwear, Seojin had received one item in return.
Still sitting on the floor of his room, he rummaged through his things and pulled out both the zipper bag containing Mom’s underwear and the object he had been given.
“So this is a hidden camera…”
It was tiny—no bigger than a pinky finger joint.
A simple little device with nothing but a pinhole lens and a USB port for charging and data transfer. That was the payment Jung Taeyoung had given him.
“With just this…”
Seojin could make so many of the things he had been imagining come true.
And because it would benefit Taeyoung as well, the man had handed it over without a second thought.
Seojin knew perfectly well that the small object resting in his palm was something the devil himself had given him—yet the burning thirst only grew stronger with every passing day.
That night in the sauna.
He wanted to feel it again: the dizzying excitement, the overwhelming guilt, and the ecstatic sense of corruption.
The masturbation Taeyoung had put on display today had been enough to faintly recall that night.
“…”
And if he used this hidden camera, even more males would flock to Mom. Once she became prey, they would violate her without mercy.
A shiver raced through him.
Imagining his strong, unyielding mother—the woman he could barely even talk back to—being ravished and defiled by other men sent a dizzying chill racing down his spine.
Seojin carefully closed his fingers around the tiny object and hurriedly began erasing every trace of what he had done.
Today was the day Mom had decided to check, on a regular schedule, whether he was studying properly.
No matter what, she would come home early, so he washed the cum-stained underwear as fast as he could and learned how to use his newly acquired weapon.
Time flew like a loosed arrow. Night deepened, and Mom finally returned home.
“I’m home. Did you eat dinner?”
Mom offered her usual perfunctory greeting as she came in, looking a little tired.
It was a weakened appearance he would normally have missed completely, because he was always so afraid of her.
Seojin crushed the lewd desire slowly rising in his chest and greeted her as if nothing at all were wrong.
“Yeah. You should eat too, Mom. I’ll fix something.”
“Thank you. Then I’ll wash up first—can you get it ready while I do?”
“Y-yeah.”
Pretending to stay calm, Seojin stammered the moment she mentioned washing.
But tired Mom paid no attention to his agitation. She simply took her change of clothes and disappeared into the bathroom.
The soft click of the bathroom door closing seeped into his ears.
His heartbeat grew louder and louder, like a drum being beaten.
Seojin’s trembling eyes locked onto the quiet bathroom door and stared as if trying to see straight through the thick wood.
In the tension where every second felt like eternity, the sound of running water soon began on the other side.
“Hoo… hoooo…”
He hadn’t been caught.
That was the first thought that flashed through Seojin’s mind.
Right now, the hidden camera he had gotten from Taeyoung earlier was installed inside that bathroom.
Mom’s dense, naked body, currently standing under the hot spray, was being captured by the lens.
With hands still trembling from tension, he hurriedly prepared her dinner.
Even while he cooked, every nerve in his body stayed fixed on the bathroom; he nearly spilled the side dishes more than once, but somehow he finished.
And just then, the water sound from the bathroom cut off abruptly.
Click.
With the sound of the bathroom door opening, Mom stepped out into the living room in her usual light clothes.
Drying her still-damp hair with a towel, she looked exactly the same as always.
“Kimchi stew today.”
“Yeah. It’s what you like, Mom.”
No sooner had the words left his mouth than Mom’s brow furrowed sharply.
Like a thief with a guilty conscience, Seojin jumped at her sudden change in mood.
“You…”
“Wh-what??”
“Did you think I’d skip checking whether you’re actually studying just because of this? Absolutely not. I’ll go over everything thoroughly later, so wait in your room.”
Apparently Mom had decided he prepared her favorite food just to butter her up.
Seojin let out a deep, silent sigh of relief and continued in a calm voice, as if it didn’t matter either way.
“Then I’ll hit the bathroom and head back to my room. Come when you’re done eating, Mom.”
“…You’re oddly confident today. Fine.”
Avoiding her suspicious gaze, he slipped quickly into the bathroom.
The room was still thick with steam and filled with a woman’s body scent that stirred a strange excitement.
But Seojin paid it no mind. He quickly retrieved the hidden camera he had stashed there and returned to his room.
“Hooo…”
He looked down at the tiny object resting in his palm, already wondering what treasure might be sleeping inside it.
But he pushed aside the joy of unwrapping a gift and decided to deal first with the obstacle that stood in the way of continuing this life.
Soon after finishing dinner, Mom came to his room and began checking his study progress and learning level.
Her face, which had been stern throughout the inspection, gradually relaxed, and he easily earned her satisfaction.
It was the result of lust-blinded Kim Seojin mastering the most efficient, high-yield study methods he could find—anything to shave even a little time off his studying.
