The Line We Crossed
A slick, wet tongue slipped between my lips without warning.
“Mmph—.”
Yuna wrapped both hands around the back of my neck and greedily explored the inside of my mouth.
Every time her tongue swept across every corner of it, a sharp thrill raced down my spine.
“Chup, schlup…! Haaup….”
“Ugh….”
The wet, obscene sounds of our joined lips echoed through the karaoke room.
I tried to pull my head back as my breath grew short.
But Yuna climbed onto my thigh, put her full weight on me, and drove her tongue even deeper.
Her top rode up, and the texture of her skirt brushing against my leg pressed fully against my thigh.
I have to push her away…!
The remaining shred of reason in my head was desperately sounding the alarm.
Even after hearing her entire confession, I couldn’t let myself get swept up like this.
This wasn’t a normal relationship.
But while my mind screamed, my body was already surrendering to her seduction.
As she rocked her hips and ground her core against me, my painfully hard length pressed against that secret place beneath her skirt.
Yuna slid the hand that had been groping my chest lower, stroking over the front of my pants.
“Haa…! Haa…!”
Breathless, Yuna pulled her lips away just enough to gasp for air.
Her half-lidded eyes were already glazed with pleasure, shining with hazy lust.
A long string of saliva hung from the corner of her mouth, glistening under the colored lights.
“I’m going crazy…! So hurry…!!”
The moment Yuna whispered that plea and reached for my zipper—
Click.
The door suddenly opened.
“Sir, your time is—Huk!”
The employee froze on the spot the instant he saw us.
“Ah…!”
In my panic, I reflexively pulled Yuna into my arms to hide her identity.
She must have been startled too; she buried her face in my chest and didn’t move an inch.
“Y-your time’s up… If you want to keep going, please come to the counter.”
The clearly embarrassed employee hurriedly shut the door and left.
Only after the sound of his footsteps faded—
“Huuu—.”
The tension finally broke, and I let out the breath I’d been holding.
Thanks to that, the sticky heat that had filled my head cooled down in an instant.
I quickly fixed my clothes and covered the front of my pants.
When I glanced beside me, Yuna was also straightening her messy hair and putting her mask back on.
Beyond it, her eyes were filled with clear disappointment and frustration at being interrupted.
“…Let’s go.”
I deliberately lowered my voice and spoke firmly.
“It looks like other customers are starting to come in. If we stay any longer, we’ll really be in trouble.”
Yuna pouted but still nodded at my words.
She seemed quite shocked that we had almost been caught in such an intimate moment.
We practically fled the karaoke room, avoiding the counter.
Outside, the sun had already begun to set.
On the way home, neither of us said a word.
Only an awkward, uncomfortable silence lingered between us.
The shocking confession from the karaoke room, the dizzying skinship that had nearly gone all the way.
My head was a tangled mess. I had no idea where to even begin.
She’s… addicted to me…?
Yuna’s desperate, almost screaming confession kept echoing in my ears.
It wasn’t just that she couldn’t forget me.
My very existence had become an irreplaceable drug for her—an absolute necessity for survival.
I had no idea how to handle something so bizarre.
Lost in thought, I walked until we somehow arrived in front of the officetel.
Yuna stopped and looked at me.
The hazy madness from earlier had faded from her eyes, but they still trembled with unease.
“Dohun…”
Yuna gently grabbed my sleeve.
“Everything I said in the karaoke room… I meant it. I need you so badly. Your scent, your warmth, the pleasure you give me… Without those, I… I really can’t take it.”
Her sorrowful voice rang in the air.
“I won’t ask you to date me. If it’s too much for you… we can just be partners. So… please don’t abandon me. I’m begging you.”
Tears welled up in her eyes again as she looked up at me.
How was I supposed to respond to this?
Could I really handle Yuna’s twisted desires?
If the problem really was that I drove women insane, was I doomed to never escape this curse for the rest of my life?
“I’m pretty tired from walking around all day… and after hearing that shocking story in the karaoke room, my head’s a mess too.”
I forced a smile, trying to wrap things up for now. Yuna’s shoulders visibly slumped.
“Go inside and rest. I need to sort out my thoughts too.”
“…Okay.”
Yuna answered weakly, head hanging low.
Watching her walk away toward her apartment, I clicked my tongue bitterly.
Click!
Only after hearing her door shut did I enter my own place next door.
“Haa…”
I sprawled out on the bed and stared blankly at the ceiling.
I could still feel the sensation of Yuna’s lips on mine.
Her suggestion.
We wouldn’t date, but we’d be partners who satisfied each other’s desires.
My mind kept rejecting it, saying it was wrong, but my body was already secretly heating up at the thought of what would come next with her.
What the hell am I supposed to choose?
One thought led to another.
To organize them, I headed for the shower.
Shaaaa—
The water poured down on my head.
Even as it ran over my skin, Yuna’s sweet scent seemed to cling stubbornly to my body.
The events from the karaoke room kept swirling chaotically in my mind.
A top idol loved by millions, begging me.
A confession that she couldn’t even live a normal life without my existence.
And those tearful, wet eyes as she clung to me, saying she’d settle for being a sex partner if that’s what it took.
“Ha…”
A dry laugh escaped me.
This was insane.
It was a situation that defied all common sense.
But when I remembered the desperation in her voice, I couldn’t just dismiss it as a lie.
The faces of my ex-girlfriends flickered through the misty haze in my mind.
Every single one of them had unilaterally announced their breakup and left as if they were being chased by something after getting involved with me.
You’re probably the type who can never receive complete love from women, just like your father.
My father’s bitter, drunken ramblings from his lifetime rang in my ears again.
If I really was the cause of all those breakups.
If there was something in my scent or my touch that gnawed away at a woman’s mind.
Then how the hell was I supposed to live?
For now… should I go to the hospital?
With that thought, I stepped out of the bathroom.
I lay on the bed staring at the ceiling, but my mind only grew clearer.
Next door.
Yuna’s presence felt vividly alive through the wall.
What was she doing right now?
Was she agonizing over the secret she’d revealed to me?
Or was she thinking of me again and comforting herself?
As my imagination ran wild, a heavy heat gathered in my lower body.
I roughly scrubbed my face with dry hands and pulled the blanket over my head.
My reason kept warning me.
Yuna was psychologically at the edge of a cliff right now.
The fact that she’d fled alone to this rundown officetel proved it.
If I distanced myself from her in a situation like this…
…No way.
All sorts of terrible thoughts came to mind.
At the same time, a different voice whispered from deep inside my heart.
Yuna’s smooth skin.
That languid, decadent expression she only showed me.
Did I really have the confidence to completely push away all that temptation?
The next morning.
Thud.
The dull noise from beyond the wall made my eyes snap open.
My hazy mind instantly awakened, and anxiety washed over me.
Had Yuna done something extreme or impulsive?
I rushed outside and pressed her doorbell, but there was no answer.
“Yuna!”
My heart sank. I was about to pound on the door when—
Click—
The steel door opened weakly.
“……”
When I saw Yuna through the gap, I froze in place.
She looked terrible.
Dark circles hung heavily under her eyes, and her bloodless lips were dry and cracked.
But what was most serious was the trembling.
She looked exactly like an addict going through withdrawal.
“Dohun…”
Her cracked voice came out weakly.
“What’s wrong with you!”
Panicking, I stepped inside and asked.
Instead of answering, Yuna staggered and collapsed into my arms.
“Ah.”
I instinctively caught her.
Yuna rested her forehead against my chest and spoke in a powerless voice.
“I couldn’t sleep.”
“…What?”
“Because… I was scared you’d hate me.”
Her incomprehensible answer made me frown.
Yuna struggled to lift her head and look up at me.
“The way I comfort myself while thinking of you… I thought it would upset you.”
Tears welled up in her unfocused eyes.
“So last night, I tried to hold it in. Every time you popped into my head, I pinched my thighs and washed my face with cold water to stay awake. But…”
Yuna’s hands clutched the hem of my shirt like a lifeline.
“It feels like my head is going to split open, like every bone in my body is breaking…”
Yuna’s plea wasn’t an exaggeration.
Her deathly pale face and sweat-soaked hair proved the pain she was in.
In that moment, the fragile wall of reason I’d been barely holding up inside me collapsed without a sound.
I scooped her up in one swift motion, laid her on the messy bed, and spoke seriously.
“Let’s go to the hospital.”
If she got examined, her identity would inevitably be revealed.
But that wasn’t something I could worry about right now.
“I told you… I already went. They said nothing was wrong.”
Yuna pulled my hand to her cheek and rubbed against it as she whispered.
Her hot breath touched the back of my hand.
“I’ll do everything you want. I won’t be annoying… We don’t have to date. So… please?”
Yuna looked up at me with glistening eyes as she lay there.
Her voice was desperately earnest.
I sat on the edge of the bed.
The small hand holding mine was trembling pitifully.
My mind cooled rapidly, and at the same time, a decision began to take root in a corner of my heart.
I couldn’t leave Yuna alone.
If I pushed her away now, she might really break.
Even if I can’t solve the root cause, I have to get her through this immediate crisis.
I steeled myself and called her in a calm, settled voice.
“Yuna.”
“Yeah…”
“I’ll accept your offer.”
At my firm confirmation, Yuna’s eyes widened.
But before she could feel joy, I laid down the conditions in a resolute tone.
“However, there are rules we have to follow.”
“W-what are they? I’ll follow all of them. I can do anything!”
Yuna tried to sit up but staggered and grabbed my arm.
I gently pressed her shoulder back down and met her eyes.
“First, we are not dating. I’m just helping you as an old friend.”
Yuna bit her lip lightly, then quietly nodded.
“Second, I don’t know why this phenomenon is happening to you, but let’s try to fix it somehow. Whether it’s going to the hospital or working together to find a way. I’ll make an effort, and you have to as well.”
“Okay… I understand.”
“And finally.”
I put more strength into my voice.
“If this relationship starts ruining your life even more, or if a dangerous situation arises that I can’t control… then I will end it based on my own judgment.”
I knew it was a cold standard.
But to maintain this twisted bond, we needed at least some safety measures.
Yuna didn’t avoid my eyes.
“I don’t care! As long as you stay by my side, I’ll do whatever you tell me to!”
With that answer, the invisible line that had been drawn between us finally snapped.
I slowly leaned down, bringing my face closer to hers.
This time, I was the one who pressed my lips to her cracked ones first.
“Mmph…”
The moment our lips met, a suppressed moan escaped from Yuna.
It was different from the fierce kiss she’d given me in the karaoke room yesterday.
Like a castaway finding an oasis in the desert, she carefully and tenderly explored my lips.
“Chuuup, chup, chuuuup…”
“Nngh…!”
I gently held the back of her neck and parted her lips.
Her hot tongue carefully pushed into my mouth, and the wet, slippery sounds began to fill the room.
Saliva mixed. Body heat tangled.
“Dohun, chuuup— Dohun…!”
Every time our lips parted even slightly, Yuna called my name like she was begging.
Then, as if pouring out all the emotions she’d held back for so long, she dug deeper into me, craving me even more.
The touching skin grew hotter, and her body trembled.
I reached down to her waist and slowly ran my hand over her smooth skin.
“Haaah…!”
Yuna’s body arched violently in response to my touch.
Thud. Thump…
The sound of clothes falling to the floor one by one echoed.
“Haa… Haa…”
“Huu… Huu…”
The lips that had been devouring each other slowly parted.
Only then could we face each other’s changed appearances.
The pure white naked body lying beneath me was so perfect that it took my breath away no matter how many times I saw it.
At the same time, the glamorous top star who had shone under dazzling stage lights was nowhere to be found.
The only thing here now was one woman.
A fragile, pitiful woman who craved a man named Kim Dohun’s body heat and touch, breathing heavily.
Yuna lay on the bed, looking up at me with hazy eyes.
I moved between her thighs and positioned myself.
Her spread entrance was soaked, and clear fluid slowly trickled down her thighs.
My swollen cock gently touched the wet opening.
The moment it made contact, her slender body trembled faintly.
Squelch…!
The sensation of slowly pushing in.
Her insides welcomed me, tightening around my shaft without any gaps.
The feeling was shockingly familiar.
“Hngh!”
The instant we were fully joined, Yuna bucked her waist hard and let out a cry.
It was the sound of overwhelming joy as the terrible thirst that had tormented her was finally quenched.
I laced my fingers with both of hers and slowly began to move my hips.
Squelch! Squelch! Squelch!…
Every time the friction repeated, wet, lewd sounds rang out.
“Haaahng— It feels so good…! Dohun, it feels so gooood…!!”
Yuna shook her head helplessly, completely swept away by the pleasure I gave her.
Her half-lidded eyes wandered through the air before locking onto me clearly.
It was different from before.
She still craved me like a madwoman, but her eyes were alive.
The withdrawal-like tremors and deathly pallor that had tormented her were gone.
In their place, a deep flush and vitality filled her face.
As if my very existence was a medicine injected directly into her.
Witnessing that unreal change, I sped up my thrusts.
Thwack!! Thwack!! Thwack!!…
The sound of our pelvises slamming together filled the room.
Pleasure raced up my spine and struck the top of my head.
“Yuna…! I’m gonna come…!!”
“Aah! Inside…! Inside me…!! Fill me up…!! Haaaaah!!”
Yuna wrapped her legs around my waist and pulled me tightly against her.
I couldn’t hold back any longer. I drove deep into her most secret place and poured out my cum.
Spurtttt—!!!
“Ugh…!”
“Hngh…!!”
At the same time as my climax, Yuna’s inner walls clamped down on my cock like a vice.
She swallowed a cry that seemed like it would stop her breathing and trembled violently as she reached her own peak.
For a long time, hot heat filled her insides completely.
Yuna panted and buried her face in the crook of my neck.
“Haa…”
A pleasant body scent and the smell of sweat wafted from her heated body.
When the convulsions of her inner walls finally began to subside, I slowly raised my upper body and looked down at her.
“Yuna.”
I called her gently, but she didn’t answer.
Her half-lidded eyes were blankly floating somewhere in the air.
She looked slightly out of it, like someone deeply intoxicated by a drug.
But there wasn’t the slightest trace of pain or anxiety on that face.
Instead, it bloomed with joy and ecstasy, as if she possessed the whole world.
“Heu… D-Dohun…”
Between her saliva-glistening lips, my name kept leaking out endlessly.
“Yeah, I’m right here.”
When I answered and brushed her disheveled bangs aside, Yuna’s eyes curved into a bright smile.
“Dohun… My Dohun… I really, really like you…”
Yuna’s arms wrapped tightly around my neck again.
It was as if she never wanted to let go, as if she wished this moment would last forever.
A slippery sensation came from where we were still joined below.
Yuna twisted her waist slightly, savoring that sticky connection, pressing her body even closer to mine.
“Now… I feel like I can live.”
Her breath tickled my ear.
“My head feels so clear… Now that you’ve filled me up inside… everything feels better.”
That whisper was so sweet and eerie that it gave me goosebumps.
It wasn’t just the afterglow of a simple relationship.
My very existence had become her one and only salvation.
The face of Yuna kissing my cheek with unfocused eyes looked exactly like a devotee with blind faith.
“Thank you, Dohun… for not abandoning me.”
Yuna rubbed her face against my chest, letting out a breath filled with happiness.
Then, as if the intense tension had finally released, her eyelids slowly closed.
“Keep… holding me like this…”
With that sleepy murmur, the sound of steady breathing began to fill the room.
She had fallen into a deep, unconscious sleep while still holding me in her arms.
I slowly pulled myself out of her embrace and lay down beside her.
I let out a long breath while staring at the ceiling.
A famous female idol sleeping beside me with the most peaceful expression in the world.
A woman bound to my existence, drunk on its pleasure, smiling happily.
The realization that I had crossed an irreversible line finally sank into my skin.
But I didn’t regret it.
Just as she was addicted to me, I had already been captivated by the way she looked up at me moments ago.
Pushing aside my complicated thoughts, I carefully wrapped my arms around the shoulders of the soundly sleeping Yuna.
It was the moment our strange and corrupted cohabitation dropped anchor.
