Day 2 – Mudpit

Long past midnight, Gwak Hoon was still awake. Normally, he’d be sound asleep by now—but tonight was different.

With a remote in his left hand, he watched the screen. He’d deliberately muted the sound. There was no need to hear their noisy moaning to know just how aroused they both were. How obsessed with each other they were—how utterly satisfied—it was all written plainly across their faces.

Crass as it was, their sexual chemistry was insane.

Both the one thrusting and the one getting fucked were completely lost in it.

They climaxed—both of them—through penetration alone, no kissing, no foreplay. Even through the screen, their orgasms were explosive.

Tsk. No fear of STDs, fucking raw without a condom, and came inside three times.

Three rounds of penetrative sex over the course of four hours, and not once had the one Gwak Hoon had been watching—Sailor 1—so much as touched or sucked a nipple. If they were still hypersensitive, the bottom would’ve begged to be sucked. Apparently, the training effect had worn off. A lot.

Frowning, Gwak Hoon turned to Sailor 1’s schedule log.

Let’s see.

One Developer Class session.

While the other Sailors had gone through three sessions, this one had only had one.

“Drug administration to be done every other day. In unavoidable cases, a minimum 12-hour gap must be observed.”

Manager Kim’s note in the margin was, at least, reasonable.

Gwak Hoon nodded, recalling the CCTV footage from earlier.

Sailor 1 had shown extreme reactions to the drugs. Unexpected, for someone who popped narcotic painkillers like candy. There had been one violent outburst that caused concern, but it was a one-time incident. Most of the time, he’d simply passed out. He’d even blacked out during the Developer Class session.

Because of that, they’d been extremely cautious placing him in Eden—but fortunately, it had turned out to be unnecessary. Somehow, during this round in Eden, he’d made it nearly to the end. Thanks to that, he’d provided exquisite entertainment.

Even Gwak Hoon had applauded in real time while watching.

Contrary to his rather uptight first impression, Sailor 1 was an unusual gem—brimming with potential. And brave, too. Despite being weak himself, he’d thrown his body in front of someone weaker to protect them.

While other able-bodied guys hung back, he had protected two people. Even the one who’d just beaten him up—he’d shown that bastard mercy.

Gwak ⊛ Nоvеlιght ⊛ (Read the full story) Hoon had never seen anyone like that before, and he liked it. A lot.

Still, he was deeply displeased.

Among the seven Sailors who received “gifts” yesterday, Sailor 1 alone hadn’t used his nipples during sex.

The fact that they hadn’t been touched at all was unforgivable. Almost insulting.

Gwak Hoon made a note to be passed on to Manager Kim:

First: Resume Developer Class. Double the intensity. Sailor 1 will receive the third-round level of training. A staff member capable of CPR must be present at all times just in case.

From what he could tell, the other Sailors’ sensitivity had diminished too. So this round of training would be harsher than before.

Ideally, he wanted them to cum just from a gust of air—but he’d save that kind of eye-candy for the main party.

Second: Post-training, retouch nipple tattoos. Double the current pigment saturation on both nipples and areolas. For Sailors with more developed upper pectorals, reduce areola size. For those with balanced upper and lower pecs, enlarge them.

Normally, he wouldn’t bother. But Gwak Hoon was a greedy man—and meticulous.

As with most gym-honed men, if the upper chest was built but the areolas enlarged, it looked terrible. Worse than leaving it alone.

He’d already adjusted widths for aesthetic reasons, but some were still unsatisfactory—so a few would be reduced. On the other hand, implants like Han Seoho’s, which created symmetrical development—or a flat-chested frame like Sailor 1’s—yielded far more satisfying results.

In terms of chest alone, Sailor 7 was closest to Gwak Hoon’s ideal. Sailor 7 had the only well-balanced upper and lower pecs, and his natural chest was fairly large. He was also the only one who reminded him of Yeonseo.

While Gwak Hoon usually preferred natural-looking nipples, for this party, he wanted something more stimulating—more artificial.

After all, this was his 80th birthday celebration.

Might as well make them special.

He imagined nipples and areolas dyed in a lurid shade of pink and grinned to himself.

Third: During sex, condoms must—

At that moment, there was a knock.

“Come in,” he said without looking up, continuing to write:

—must be worn at all times. Ejaculating in the mouth only is permitted. If violated—

“You never sleep, huh? Is it an old-man thing?”

The mocking voice was thick with irritation.

“Watch your fucking mouth.”

“You drag me here at this hour and expect manners?”

His grandson walked right in and flopped onto the couch. “Flopped” wasn’t even accurate—he basically sprawled.

If violated: 10 penalty points per internal ejaculation.

Gwak Hoon finished his note and stood.

The massive screen still showed an ongoing sex scene, but his grandson didn’t spare it a glance.

Instead, he asked, smugly, “Not bad, huh?”

He was confident—and why not? With a face and body like his, it was expected.

“What the hell were you thinking, going raw with someone like that?”

Gwak Hoon scolded.

“First you act like you won’t even cum inside, then you go and blow your load three times. Tsk.”

The grandson snorted.

“Test results came back clean. If you’re worried, worry about him.”

“There are tons of STDs that don’t show up in tests!”

“Which is why he’s the one at risk, not me.”

He talked back, point for point.

Still, Gwak Hoon didn’t back down. They were both the kind of people who couldn’t rest until they said what they needed to.

“How do you know what kind of shit’s been in that hole? He didn’t used to be like this—it’s even more suspicious.”

“Getting bent out of shape over one round of raw sex. Like I haven’t had my dick sucked how many times already? You gonna count those too?”

He wouldn’t give an inch.

They argued back and forth a few more times, but it went nowhere.

Eventually, Gwak Hoon gave up.

“How long do you plan to stay down there?”

Finally, the question he’d wanted to ask.

The kid had insisted on joining the project and forced his way in—only to go undercover with the crew, plotting with his cousin Tan without saying a word.

Said he was “hunting.”

He wanted to catch the rats himself—the ones that had been a thorn in their side throughout the entire operation.

There was no stopping him. Even if he’d tried, the kid wouldn’t have listened.

But still—he kept butting in.

Volunteered to be given as a gift. Got involved in that fight and nearly got someone killed.

He was a fucking handful.

“I’ll stay. Gotta be there when you blow out the candles.”

Smartass.

Gwak Hoon sighed.

He wasn’t worried about being exposed.

He was worried about Sailor 1.

He’d known his grandson was interested—but hadn’t realized it was serious enough to get into a fight over.

How the hell did their tastes end up so identical?

It was both satisfying and troubling. He hadn’t meant to hurt his grandson.

The Sailors were selected solely for Gwak Hoon. During the party, they’d do nothing but suck, fuck, and get fucked by him. His grandson knew that.

But that wasn’t the only problem.

If this were just about sex, it wouldn’t be a big deal.

Gwak Hoon had a secret—a dark and dangerous one.

Sex with the Sailors was a given. But that wasn’t all.

He planned to violate them with every imaginable toy. And then, he was going to play some very, very dangerous games.

Broken bones would be the least of it. In the end, blood would pour from every hole.

None of the Sailors would leave this place alive.

That was the real reason Gwak Hoon had created this project.

Of all the dozens—no, hundreds—of sex partners who had passed through his life, not a single one had ever seen his true nature.

Only Yeonseo and Manager Kim knew.

Gwak Hoon still loved and mourned Yeonseo, because they’d shared the same tastes. Every three months, they’d host big or small parties to indulge themselves—and Manager Kim had always handled the cleanup.

The reason Gwak Hoon had built his paradise deep in the mountains wasn’t just to hold illegal sex parties.

It was the easiest, most convenient way to dispose of bodies—without consequences.

Yeonseo and Manager Kim had been perfect allies. True accomplices.

But now...

Only one remained.

Ah... my beloved Yeonseo. My soulmate.

Since his death, Gwak Hoon might as well have been dead too. No matter how many people he fucked or killed, it never satisfied him. It brought him no joy. So he’d stopped.

It had already been over a year.

But this time was different. This time, he would enjoy it completely—for everything he’d missed, and for Yeonseo’s sake.

One per day.

Lucky Seven.

That was why he’d chosen seven.

“You interested in that one?”

His grandson let out a sharp laugh.

“You’re being weird again.”

“If you are—”

“Drop it. You’re acting like we fell in love after one fuck.”

He yawned.

“Tan says you volunteered to go down there?”

“So what if I did? He was the only one remotely my type.”

He was clearly irritated now.

“Everyone else made me think of Uncle Jongsu. Gave me the creeps.”

“Gwak Yeol!”

Gwak Hoon shouted.

“Watch your damn mouth. How dare you—”

“I’m not deaf, you know.”

His grandson didn’t even flinch.

“Why’d you call me up here? Don’t tell me it was just to nag me about condoms.”

He didn’t care if Gwak Hoon was furious—he said whatever the hell he wanted.

Gwak Hoon sighed deeply and walked to the desk. He picked up the remote, turned off the sex video, and switched to another feed.

A small dot moved across the black screen.

It was a rat.

He’d thought they’d caught it.

He’d already uncovered the fact that his grandson Jun and his lackey, Deputy Jeong Hyeonwook, had bribed the IT room staff. He’d assumed the rat was their doing.

Tan had been convinced, and Manager Kim had produced matching evidence. It had all seemed settled.

But an hour ago, the rat reappeared.

As if mocking them—even after the IT guy and Jeong had both been “cleared out.”

Tan had been so sure Jun was behind it that he rushed off to confront him. He still had at least two hours before reaching Jun’s hideout.

“A rat, huh? Thought they were all caught.”

At last, the grandson sat up, eyes sparkling.

For a moment, Gwak Hoon wondered—maybe their tastes really were the same.

“When was this recorded?”

“An hour ago.”

“What about Tan?”

“Went after Jun.”

“No way.”

His grandson grinned.

“I’m telling you—it’s not Jun. I guarantee it.”

“Then who?”

“How the fuck would I know? I’m just telling you—it’s not him.”

He smirked, tauntingly.

“He doesn’t have the balls. He’s stupid. You know that better than anyone.”

Yeah. Gwak Hoon did know.

Jun didn’t have the guts—or the brains—for something like this.

Still, this time had been different.

He’d been desperate to join the project, and worked harder than anyone to recruit for Gwak Hoon’s favor. Thanks to him, they’d found someone like Sailor 1.

Since the program began, he’d practically lived on-site. Rewatching CCTV footage obsessively. Managing the reserve staff without even being asked. It had driven Tan nuts.

If Jun hadn’t hit one of the reserves, he’d still be here playing head manager. He’d staked everything on this.

Why?

What if it wasn’t to impress—but to sabotage?

Then, the moment he was kicked out, he vanished. Only to be found receiving real-time CCTV from the IT guy he’d already bought off. The spilled coffee had been a cover—the guy had nearly been caught.

Of course, Jun had denied everything. Swore up and down that he’d never worked with the cops. Cried about being framed.

But Gwak Hoon had seen Deputy Jeong and the IT guy get their teeth and nails ripped out. He’d been sure Jun was lying.

...Was he?

Could that dimwit really have planted the rat?

Or had he been duped by the police?

“Let it run wild,” the grandson said.

“What if it causes trouble?”

“What kind of trouble?”

He sounded completely unfazed.

Yeah. What trouble?

Even if something did happen—they were all rats in a cage. Helpless sheep he could crush any time.

When did I get so damn cautious? Gwak Hoon thought bitterly.

His grandson rose from the couch and approached.

“Just wait, Grandpa.”

He grinned. And something wild gleamed in his eyes.

“That’s what makes it fun.”

He was a beast, no doubt.

And in that moment, Gwak Hoon was certain—not maybe—that their tastes were the same.

He smiled with satisfaction. He might finally have a companion who understood him.

“Wait... the bracelet’s gone?”

“What?”

“That fucker’s not wearing a bracelet.”

Gwak Hoon’s mind snapped back to full alert like a bucket of ice water dumped over his head.
