Chapter 1 — My Girlfriend Became My Friend's Lover

Once a popular student retreat, the old building now stood abandoned, forgotten by time, its crumbling walls casting long shadows in the dead of night.

It was past ten, and the silence around was absolute—like the breathless hush of death itself.

Stepping through the entrance, David Hong felt the dim glow of the bare incandescent bulbs lining the long corridor only deepened the dread. The air was thick, eerie, as if ghosts might leap from the walls at any moment.

Along one side of the hallway were half a dozen large doors—each leading to a spacious room.

David Hong had never known fear in his life. But now, his legs trembled beneath him, gripped by a primal terror he couldn’t suppress.

Tense and alert, he crept forward, searching for his friend who might be trapped somewhere inside.

“Ugh! Too many rooms—I can’t even get a sense of this place!”

Just then, he sensed movement—someone approaching.

It came from outside the building. Voices. Laughter. Footsteps drawing closer.

“Hmph. Good. I don’t know who they are, but I’ll face them head-on. Phew…”

David Hong exhaled sharply, trying to steady his nerves.

And then—a voice, thick and grotesque, slammed into his ears like a physical blow.

“Puhahaha! We’ve got a toy at last! Time for a little game tonight. Kehahaha!”

“What? So we’re killing them tonight?”

“Khehehe… Who knows? Life or death—it all comes down to luck. Kahahaha!”

Life or death… luck? David Hong shuddered.

He didn’t need to guess—the “game” they were talking about could only involve his friends.

Damn… This is worse than I thought. What do I do?

But he had no time to think.

He couldn’t run. He didn’t even know what kind of monster he was dealing with. Charging in blindly would be suicide.

He needed to hide—just until they entered—watch them, learn their moves.

His eyes darted to the nearest door. He grabbed the handle.

Click. Click. “What the—? Locked!”

He hadn’t expected that.

Panicked, he rushed to the second, then the third door—both locked tight.

Shit. This is bad. What now? Ugh…

Footsteps grew louder. Closer.

With no place left to hide, David Hong’s heart pounded as he reached for the final door—the last one remaining.

“Please… please open…”

Was it fate’s mercy? The handle turned with a soft click, and the door slid open.

But the moment it did, a scream pierced his ears—shrill, desperate, unmistakably female.

“Kyaa! Aaah!”

David Hong didn’t stop to see who it was. He lunged inside just as figures entered the building behind him.

He slammed the door shut, pressed his back against the wall, and held his breath, listening.

Silence. Then—soft, muffled sobbing.

“Uhh… huuu…”

Only then did he remember the scream. He wasn’t alone in the room.

Slowly, he turned his head toward the sound.

And what he saw nearly made him cry out.

“Wha—? No… impossible… ugh…”

Spread-eagled on a giant dartboard-like disc, a naked woman was tied down—arms and legs stretched wide in a crude “X” shape.

David Hong knew he shouldn’t be looking. This wasn’t the time.

But what man could look away from a naked woman?

The room was dim, but he strained his eyes—her body was stunningly slender, perfectly shaped.

From her perspective, the pose was humiliating beyond words.

Her full, round breasts thrust upward. Her legs spread so wide they were nearly straight. No man in the world could stand before such raw, exposed flesh and remain unmoved.

It was the kind of sight that would ignite any man’s desire.

Especially for David Hong, who had always been weak for women.

Under normal circumstances, he’d have pounced, hands roaming greedily over her soft tits and tender pussy. But now—now he couldn’t tear his eyes away, even as he whispered:

“Do you… know a guy named Eric Gicheol?”

Instead of answering, she burst into tears.

“Huuu… ugh… huuu…”

“Don’t cry. I’m not here to hurt you.”

He stepped closer, trying to calm her.

But the moment her face came into view—David Hong froze, trembling.

“Wha—? Sarah Yumi?”

“Huuu… huuu…”

David Hong’s eyes widened in shock. She closed hers, turning away, tears streaming down her cheeks.

He stood dumbfounded.

Sarah Yumi—naked, bound—had grown up in the same neighborhood as him. Until last year, she’d been his girlfriend.

But when they entered college, her beauty caught the eye of Eric Gicheol—a rich, spoiled only son from a powerful family.

With endless money and influence, Eric Gicheol had stolen her away.

Just a month ago, David Hong had no idea.

He’d gone for a jog in the woods when he spotted Eric Gicheol’s bright red foreign sports car. Excited, he rushed over and yanked the door open.

And there—inside—was a scene he never expected.

Sarah Yumi, half-naked, cradled in Eric Gicheol’s arms.

At first, he’d raged—how could his best friend steal his girl? He’d even thought about killing them both.

But in the end, he decided—he wouldn’t ruin his life over one woman.

After that, he let her go.

He and Eric Gicheol drifted apart. They hadn’t spoken since.

Until three hours ago.

David Hong had received a call—Eric Gicheol’s voice, frantic, desperate.

“Huuu… David Hong! Help me! I’ve been kidnapped!”

“What? What are you talking about? You’re kidnapped?”

“I’ll explain later! Huh! Just save me!”

“…Fine. Where are you?”

Reluctant, but unable to ignore the panic in his voice, David Hong asked.

“There’s that place we used to hang out… the lake. See the island in the middle? There’s a big building there—ahhh!”

The call cut off with a scream.

Big building… David Hong immediately thought of the old retreat.

Hearing the urgency, the terror in Eric Gicheol’s voice—he knew this was serious.

Why would he call me of all people?

Without hesitation, he rushed out, hailed a taxi, and headed for the lake.

After over an hour, he reached the shore. But the island in the center—no boat.

He searched frantically—then spotted a small rowboat. He rowed across, tied it at the edge, thinking he might need it later.

A former special forces soldier, David Hong held an 11th-degree black belt in taekwondo, judo, and aikido. He trusted his body, his training.

He entered the building.

But the moment he smelled the metallic stench of blood—thick, coppery, fresh—his confidence wavered.

And seeing Sarah Yumi, bound and exposed on that disc… he understood.

These weren’t ordinary criminals.

No law-abiding person would treat a human like this.

His mind spun. He stared at Sarah Yumi.

Her face was pale with terror. She couldn’t even open her eyes—ashamed of her nakedness.

Once, he’d jerked off countless times imagining her body. Now, seeing her completely bare—real, vulnerable—he felt… nothing.

But he couldn’t look away.

Then—his eyes dropped to her spread legs.

And he froze.

Beneath the dark patch of pubic hair—right below her soft, delicate pussy—was a knife.

A long, sharp blade, plunged deep into the flesh.

It was buried less than a centimeter from her groin.

One wrong move, and the razor-sharp edge would slice open her tender inner lips.

Now he understood—she couldn’t move.

“Just… hold on. I’ll get you out.”

“Huuu… huuu…”

He approached, but the moment he touched the restraints—his hope shattered.

Thick leather belts, tightly bound around her wrists, ankles, and neck.

Impossible to break by hand.

“Then… I’ll need a knife.”

He turned to the blade embedded between her legs.

“Wait. I’ll get you free. Just… stay calm.”

He gripped the handle.

It was buried deep—resisted his pull.

“Ugh! Ahh…”

As he strained, his hand brushed against her pussy.

Soft. Wet. The delicate inner lips grazed his knuckles.

Unconsciously, he looked up.

Her eyes—closed in shame—had flickered open, filled with something… expectation.

Then, realizing what he’d touched, she squeezed them shut again.

She was avoiding his gaze. She thinks this is punishment, David Hong realized. For betraying me.

Until now, fear and urgency had numbed him.

But the moment his skin touched her wet, trembling flesh—something stirred.

A dark, forbidden heat rose within him.

He pretended to struggle with the knife—while deliberately brushing his fingers against her clit.

Her pussy… just like her face. Beautiful. Tempting.

“Ah… careful. I don’t want you to get hurt.”

He pretended to worry—then used his fingertips to gently lift the folds of her slit.

As he pulled on the knife, his fingers slipped deeper, rubbing slowly, rhythmically.

Again. And again.

Then—something unexpected.

“Huuu… ahh… ahh…”

Sarah Yumi’s sobs changed.

No longer just fear and shame—now, a strange, breathy moan.

David Hong felt it too—pleasure, twisted and electric, as he rubbed her.

And despite her terror, despite her nakedness—Sarah Yumi felt it.

Her body responded—tingling, trembling.

Just as the tension built—suddenly, loud voices echoed from outside.

David Hong snapped to attention.

Heavy footsteps—coming straight for the room.

Thud. Thud. Thud.

He needed to hide—now.

Only one spot: behind the round disc where Sarah Yumi was tied.

He slipped behind it, just as—

Click. Creak. SLAM!

The door burst open.

He hadn’t seen the man yet—but the heavy, dragging footsteps told him: this was no ordinary man.

“Hahaha! Been good, haven’t you? Cute little thing!”

A deep, guttural voice filled the room.

The man laughed, then approached Sarah Yumi, dragging his feet.

“Hmm. No blood… so you didn’t struggle much.”

Thud! The disc shook. He’d pulled the knife from under her.

“Puhaha! Let’s see… huh? Wet? Seriously?!”

Wet? David Hong’s mind raced. He touched her? Right now?

But before he could process it—Sarah Yumi screamed.

“Aaah! Ahhh! P-please! Aaah!”

“Puhahaha! Crying makes you even cuter. Khehehe!”

The man laughed, mocking her.

Then—click—the door opened again.

“Hey. What about this guy?”

“Huh? Oh, him? Looks like this bitch’s boyfriend. Just throw him in.”

David Hong’s blood ran cold.

Eric Gicheol.

“Aaah! Ouch!”

A thud. A cry.

Someone was thrown into the room.

It was Eric Gicheol.

Naked. Beaten.

His face swollen, bruises covering his body.

“Don’t whine, you little shit! Get on your knees!”

“Huuu… huuu…”

Terrified, Eric Gicheol dropped to his knees.

“You had fun with her, didn’t you? Now it’s my turn. Ehehe~”

The man laughed, then flipped the disc.

David Hong couldn’t see—but he knew.

Sarah Yumi’s head was now down. Her spread legs—facing the ceiling.

“Look at her, you bastard! Open your eyes and watch! Got it?”

The man stepped forward, laughing.

David Hong caught a glimpse of his feet.

Over 300 millimeters. A giant.

Deep voice. Massive feet. This man was a monster.

All David Hong could see now was Eric Gicheol, kneeling in the corner, trembling.

“Hey, you little shit! Not looking? Fine. Let me force your eyes open!”

“Wha—? Ugh! Huuuu!”

Eric Gicheol jerked his head up, eyes wide with terror.

“Hehehe… That’s better. Ohhh… now it’s getting hot. Heheh…”

David Hong didn’t need to see.

He knew.

The man was rubbing Sarah Yumi’s pussy—just like he had.

Maybe even deeper. Maybe fingers inside her.

He glanced at Eric Gicheol.

Tears streamed down his face as he watched his lover being violated.

How could he stay calm?

“Ohhh… look at this! She’s dripping! Heheh…”

The truth?

The man was violating her—his grotesque, hairy hand rubbing her clit, fingers thrusting deep into her wet hole.

“Aaah! P-please stop! Ahhh!”

David Hong listened—her moans, his laughter—and imagined the scene.

Her legs spread wide to the ceiling. Her pussy—ravaged by a monster’s hand.

Yet her body betrayed her—aroused, wet, needing.

Women—even in deep sleep—leak fluid when touched.

Sarah Yumi was no different.

Fear. Terror. But beneath it—pleasure.

Then—another moan.

“Aaahh~ Ah! Stop… haaah~ ahh!”

And Eric Gicheol’s face twisted in agony.

David Hong saw it—fingers thrusting deep, pumping her.

The wet squelch—it made his skin crawl.

Slip. Slap. Slip.

Her pussy was soaked.

And then—Sarah Yumi screamed.

“Aaahh! S-stop! I… I can’t… huuu… huuu!”

“Ohhh… look at her! Puhahaha!”

A stream of liquid trickled down—splashing onto the floor.

A familiar smell.

She pissed herself.

From pleasure.

David Hong stared—disgusted, yet aroused.

How could she feel this much? How could she come like this?

He felt a strange throb in his groin.

Then—Eric Gicheol snapped.

Seeing his lover humiliated, pissing in ecstasy—he roared.

“Hey! You motherf—!”

“Huh? What’s this?”

The giant laughed. “This little shit wants to die! Khehehe!”

Eric Gicheol froze—cowed by the monster’s voice.

“You want to die? Fine. You’re done.”

The giant stepped toward him.

And for the first time—David Hong saw him.

Over two meters tall. A mountain of muscle.

The giant grabbed Eric Gicheol’s arm—snapped it with a sickening crack.

“Aaah! AAAAAH!”

Eric Gicheol screamed.

The giant walked to the disc—picked up the knife.

Then returned.

“Haa… haa… please! I’ll do anything! Money! Anything! Puhuuh!”

“Oh? But I don’t want money.”

The giant grinned, pressing the blade to Eric Gicheol’s throat.

“I want your skin.”

He slashed Eric Gicheol’s arm.

“Aaah!”

David Hong couldn’t watch anymore.

He was trained. Strong. Fast.

If he hit the giant’s weak spot—he could win.

He lunged.

“Yah!”

The giant turned.

David Hong’s flying side kick—perfect—slammed into the giant’s temple.

“Huh? What the—? Ugh!”

Most men would’ve dropped.

But the giant wobbled—then stood.

He rubbed his head, eyes blazing.

“What…? You little flea! I’ll kill you all!”

He charged.

David Hong dodged the first punch—then the second.

But the giant’s swings were relentless.

David Hong was driven back—cornered.

“Haha! You’re trapped, rat! Haha!”

“Don’t celebrate yet. You’ll die by my hand.”

“Hmph. Big talk. Let’s end this.”

The giant raised his fist—swung down with crushing force.

David Hong’s eyes flashed.

He lunged—foot driving into the giant’s solar plexus.

“Ugh! Aaah!”

The giant collapsed, gasping.

But David Hong didn’t stop.

This man was a killer.

He grabbed the fallen knife—pressed it to the giant’s throat.

Kill him. End it.

“Nooo! Don’t!”

Sarah Yumi screamed.

She was terrified—not of the giant, but of death.

Who could take a life so easily?

“Fine. I’ll cripple you instead.”

David Hong slashed the giant’s thighs—deep, brutal cuts.

Then shouted to Eric Gicheol:

“Eric! Watch the door! I’m freeing Sarah Yumi!”

He rushed to her—used the bloody knife to cut the thick leather belts.

“Huh? This isn’t cutting easily…”

The blade was sharp—but the leather resisted.

He needed to say something. Calm her.

“Did… did he touch you? Earlier?”

“Mmm… don’t tease me… I’m not in the mood… ugh…”

She blushed—remembering.

Was it teasing? No.

He regretted asking.

“So what? We’re in this mess. What’s there to hide? Where did he touch you?”

“Ah… I don’t know…”

Her face burned.

Finally, the wrist restraints snapped.

Only her ankles remained.

“Sarah Yumi… to cut this, I need to turn the disc. It’ll… expose you more. Is that okay?”

She knew what he meant. Turning it would spread her even wider.

She hesitated.

“What do I do…?”

“We don’t have time! Answer!”

“I… I don’t know… do what you want…”

He turned the disc 180 degrees.

“Huuu… ugh…”

Despite the danger—despite everything—David Hong gasped.

Her pussy—soaked from the giant’s touch—glistened, wide open.

The wetness excited him.

“Did he touch you here?” he whispered, cutting the ankle strap.

“Ahh… I don’t know…”

She avoided the truth.

But the more she denied it—the harder he got.

His cock swelled, pressing against his pants.

He moved closer—his bulge pressed against her breast.

Her open pussy—right in front of his face.

The sharp, musky scent of her arousal filled his nose.

He couldn’t resist.

As he cut the last strap—he pressed his lips to her clit.

“Did he touch you here? Did he pump you?”

“Y-yes…”

She finally admitted it.

Her pussy twitched.

He slipped his tongue inside.

Then—snap.

The last strap broke.

He pulled back—but she didn’t close her legs.

She wanted it.

“Do you want me to suck you?”

“Haa… I don’t know… do what you want… ahh…”

She’s asking for it.

He buried his face in her pussy—tongue deep.

“Aaah! Aaah!”

She was already aroused—now, she exploded.

Clear fluid gushed—dripping down his chin.

He drank it—disgusted, yet aroused.

The last strap nearly gone.

Just as she neared climax—Eric Gicheol shouted:

“Hurry! Someone’s coming!”

They snapped back to reality.

Thud!

The disc collapsed—Sarah Yumi fell forward, landing on David Hong.

She was free.

“Sarah Yumi. I’ll take out whoever comes in. You and Eric—run. Got it?”

He pressed against the wall beside the door.

“Hey! What’s going on? Had enough fun? Khehehe!”

A rough voice. The door opened.

Click!

David Hong lunged—fist aimed at the man’s temple.

The man staggered—but didn’t fall.

He was huge—built like a tank.

“Wha—? You little shit!”

He rubbed his temple—glared.

No hesitation.

David Hong kicked—hard—at his jaw.

“Ouch! Gaaah!”

Two teeth flew out.

The man wobbled—then collapsed.

David Hong rushed—stomped on his neck.

Crack.

The man twitched—then went still.

“Let’s go! Move!”

But Eric Gicheol didn’t move.

He collapsed.

“Hey! What are you—?”

Then David Hong saw it.

A knife—buried in Eric Gicheol’s back.

The first giant had thrown it.

“Fuck!”

David Hong snapped.

He stomped on the man’s neck—twisted.

Crunch.

The man died without a sound.

David Hong lifted Eric Gicheol.

He was covered in blood.

“Wake up! We have to go! Eric!”

No response.

Dead.

No time.

Sarah Yumi stood frozen—too terrified to even cry.

“Sarah Yumi. Let’s go. Now.”

They ran.

Just as they reached the exit—click.

Another door opened.

“What the hell?”

A man—built like a wrestler—blocked their path.

He looked around—grabbed something.

They used the chance—rushed outside.

Dawn had broken. The sky was bright.

They ran—didn’t look back.

“Hey! Stop right there!”

“Run! Just a little farther—my boat’s near!”

But Sarah Yumi—naked, barefoot—kept falling.

David Hong had no choice.

He slung her arm over his shoulder—his other hand gripping her breast.

Her soft, full tit filled his palm.

But none of that mattered now.

He ran—carrying her—toward the boat.

Alone, he’d have escaped.

But with Sarah Yumi—slow, stumbling—the man gained.

Less than ten meters behind.

“Hurry! Get in! Now!”

He practically threw her into the boat—pushed off—jumped in.

The man charged—ran into the water—reached for them.

But the boat was already out of reach.

“Phew… Sarah Yumi. We’re safe. He can’t catch us. Haa…”

He pulled her close—held her.

She trembled—still terrified.

After a while—she calmed.

Then whispered:

“Huuu… do you… hate me?”

“…No. I was angry. But I never hated you.”

“Huuu… then… will you take me back?”

The words he’d waited for.

He nodded—then looked down at her naked body.

She closed her eyes—ashamed—as his gaze lingered on her pussy.

By now, the boat had reached the center of the lake.

Behind them, the wrestler screamed in rage.

But something strange happened.

Even after death, after terror—excitement surged through him.

He looked at Sarah Yumi—then began to undress.

“Huh? No… here? And in broad daylight?”

She frowned—embarrassed.

But David Hong didn’t care.

If not now—he’d lose her again.

He stripped—moved close.

Sarah Yumi instinctively reached for his cock.

“Ah… but not now… later…”

She said no—but her hand tightened.

Instinct. Desire.

He laid her on the boat—spread her legs.

Her thighs—smooth, white—already slick with wetness.

He gripped his thick, hard cock—slid between her legs.

Sarah Yumi’s eyes widened.

She stared—dazed—at his massive shaft.

“What if someone sees… huu…”

But her breath was already ragged.

“Let them watch. He’s watching. And who cares? I love you. And you love me, Sarah Yumi. Huu…”

He lifted her legs—draped them over his shoulders.

“Ah… what do I do… haa…”

Then—pushed.

His thick cock plunged into her.

“Ah! Aaahh! Haaah!”

Her moan—deep, guttural—as his tip breached her.

She clung to him—arms around his neck.

At first, she’d said no.

But as his cock drove deeper—she screamed.

David Hong thrust—hard, deep—using his full strength.

Sarah Yumi had leaked fluid under the giant’s touch.

Now, under David Hong’s thick cock—she flooded.

Her pussy gushed—her moans turned filthy, loud.

“Uuuhhh… ahh! Too much! Haaah!”

She’d seen her lover die. Faced death.

Yet now—she was coming.

“Too tight… why is it so big… huuu…”

Eric Gicheol must’ve been small.

Now, with David Hong’s cock pounding her—she cried out in pleasure-pain.

David Hong thrust—half in, half out—then deeper.

Sarah Yumi—born with insatiable desire—needed more.

She clung tighter—pulled his hips closer.

His cock drove deeper.

David Hong bent her—snapped his hips.

Sarah Yumi arched—screamed—her voice raw.

He pushed until his balls slapped against her ass.

Her pussy—tight, hot, perfect—wrapped around him like silk.

He glanced back.

The wrestler screamed—watching.

Being watched—it excited them.

Sarah Yumi closed her eyes—lost in sensation.

Each thrust sent shocks through her.

She clung to him—tighter—whenever he pulled back.

She gushed—moaned—shook.

“Haaah! Something’s wrong… I’m… I’m going to come… ahh!”

She threw her head back—pulled him deeper.

David Hong knew—now.

He thrust faster.

Then—it happened.

Her body convulsed.

She screamed—flooded—a torrent of fluid gushed out.

And David Hong—came.

Jet after jet—deep inside her.

They stayed connected—still—long after.

Their tangled bodies, slick with sweat, glowed in the morning sun.

As if the future itself blessed them.

End
