Can You Turn Off the Lights?

The sound of a keyboard clacking echoed through the empty office. It was well past the time everyone else had gone home, yet here I was, alone, hammering away at the keys. I hadn't finished the paperwork I was supposed to wrap up today.

Outside the window, only moonlight filtered in. There was no sign of the work ending anytime soon. The one bright spot was that tomorrow was a company holiday, followed by the weekend—kicking off a glorious long break. But I had wanted to spend this time on my precious hobby.

I still hadn't finished the document I was working on, and there were three more left to write, plus proofreading. At this rate, I'd probably be here until morning.

I had no idea how long I'd been pulling this all-nighter when I heard the elevator, which shouldn't have stopped on this floor, come to a halt. Huh...? I'm the only one here on this floor...

The thought lasted only a second before I was sucked back into the monitor, too focused to care. Then came the sound of someone opening the office door. Only then did my attention finally shift.

I poked my head above the partition to check the entrance. No one was there. I'd definitely heard the door open, but the room was empty. A chill ran down my spine.

Maybe I shouldn't have left just the desk lamp on... I should have kept the main lights on. The dark office felt increasingly eerie tonight.

When I stopped typing, every sound in the office became audible. The ticking clock... my rapidly beating heart... and someone's footsteps...

Huh? I thought no one was here?

I instinctively checked if my legs were shaking from fear, but they had frozen solid instead. The footsteps were definitely coming this way. No doubt about it.

On pure instinct, I slowly pushed my chair back and quietly slipped under the desk, trying not to make a sound.

Wait... could it just be a yokai? Or maybe the security guard? He wasn't human—what kind of yokai was he again?

Thinking about it that way, my fear started to fade. In a world where humans and yokai lived together, why was I getting scared over something like this? It suddenly felt ridiculous.

Now that the panic had passed, I felt a little embarrassed about hiding under a desk at my age. Screw this...

I let out a mental sigh and lifted my head to crawl out from under the desk. That's when a pair of bright red lips appeared right in front of my eyes, along with round pupils staring straight at me.

"Aaaaaagh!"

Thud!

Startled, I fell backward and smacked the back of my head against the desk.

"What are you doing?"

A familiar voice reached my ears. Rubbing my aching head, I looked up to see Ha Eun-ju staring down at me with a pitying gaze.

"Ah... Section Chief Ha..."

She let out a sigh, walked over to the light switch by the door, and flipped it on. Bright light flooded the previously dark office. As a bonus, the sudden flood of illumination after relying solely on my desk lamp stung my eyes.

Squinting at her, I noticed she looked different from her usual office appearance. Her hair was tied back in a messy ponytail, she wore a casual blue tracksuit, and she had on round glasses ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠she never wore at work.

With her arms crossed, Ha Eun-ju approached my desk.

"Section Chief... what brings you here..."

"Ah... I forgot my wallet and came back for a walk. What about you, Dae-geun? What are you doing?"

She asked while glancing at the computer on my desk.

"Ugh... I was going to suggest we grab a drink since we ran into each other, but... did you do all this by yourself? You should've asked me for help."

"It's my responsibility, so I wanted to finish it myself..."

"At this rate, you'll be done around lunchtime tomorrow. What kind of colleague leaves their coworker like this? No way. This big sister will help you out."

Ha Eun-ju cracked a joke she rarely made at the office and turned on her computer. Was this what they called camaraderie? The petite woman who always seemed like a little sister suddenly looked incredibly reliable.

"What are you waiting for? Send me the files."

"Ah... yes! Sending them now."

Just having one more person in the dim office brought it to life. Until now, I hadn't realized it, but I guess I was the type who got pretty lonely.

"Done~ What time is it... Whoa! Five-thirty? Sigh, no drinking for us tonight."

By the time we finished everything, it was 5:30 in the morning. Ha Eun-ju had probably wanted to drink, but at this hour...

"I'm sorry, Section Chief. It's all because of me..."

Feeling guilty, I bowed my head in apology. She had been stretching when she saw me and let out a small chuckle.

"Instead of 'I'm sorry,' 'Thank you' would sound much better. I just wanted to help, so there's no need to apologize."

"Ah... thank you."

When we stepped outside the building, darkness still blanketed the sky, but light would soon chase it away. I kept thanking Ha Eun-ju as we walked out together.

"I really appreciate your help today."

"Not at all. It was nice working in comfortable clothes without any pressure, and chatting while we worked was actually pretty fun. Buy me a drink sometime."

With that, she waved and disappeared behind the building. I watched her back until she was out of sight.

By the time I checked my watch, it was already six. Cleaning up the empty office had taken longer than expected. I hurried toward the street to catch a taxi.

The sun would rise ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠soon. I had to get home and sleep before it did. That was my next mission after finishing the company work.

I somehow managed to hail a taxi and arrived home quickly. But I must have been a bit late—the sun was already cautiously peeking out between the buildings.

I unlocked the door and stepped inside. A little sunlight was already filtering into the house. I washed my face, changed clothes, and headed to my room to close the blinds.

But thin rays of light still squeezed through the gaps, settling inside the room.

"Ah..."

Realizing I was too late, I felt incredibly resentful. My constitution that prevented me from sleeping when it was bright... and these cheap blinds that couldn't completely block the light even though the sun hadn't fully risen yet...

I lay down on the bed out of formality, but as expected, I tossed and turned and couldn't fall asleep. It was torture. I was clearly exhausted, on the verge of collapsing, yet this inability to sleep felt like being tortured alive.

"Maybe I should go for a walk..."

I got up from bed, threw on some casual clothes, and left the house. I sat on the swing at the playground in front of my apartment and watched people pass by.

Students in school uniforms heading to class... office workers in suits on their way to work... Oh right, today was Friday? Our company had the day off, so I hadn't noticed, but it was a regular weekday.

That was a small comfort, but the exhaustion weighing down my entire body was unavoidable.

Ah... maybe I should check out some new shops worth visiting?

I dragged my heavy legs and started walking. I'd been to the yokai brothel street near the company many times, but I didn't know much about the ones close to home.

I searched for nearby yokai brothel districts on my phone and headed there. It wasn't far by bus, but I decided to walk to clear my head and get some fresh air.

After walking for a while, I arrived at the yokai brothel street behind the bar district. I wandered inside, looking around. Most shops were closed, but a few operated 24 hours.

I was observing the various shops and the yokai girls cleaning in front or smoking when someone called out to me.

"Hey there, Oppa~! Wanna come play at our place?"

Thinking it was just typical solicitation, I turned around. On a wooden bench by the street, a woman sat with one leg crossed over the other.

Her eyes were quite large and sharp. Her skin wasn't extremely pale but had a healthy glow. Her hair fell all the way to her chest. The slight smile on her lips instantly told me she was quite the mischievous type.

But what really caught my eye wasn't any of that—it was the cat ears perched on top of her head. Looking closer, two cat tails were swaying behind her hot pants.

Uh... what kind of yokai was she again...?

As I stood there silently staring, she seemed to get impatient. She stood up and walked right up to my face.

"Oppa~ Why aren't you answering?"

Startled by her sudden closeness, I lowered my gaze. The tank top she wore accentuated her figure, and though not huge, the cleavage between her breasts was tempting. Her slightly smiling mouth revealed sharp fangs that looked incredibly attractive.

She stared intently at my face for a moment before returning to her seat on the bench.

"Ugh... Oppa, you're hopeless~"

"Huh...?"

She sighed and said something meaningful.

"You couldn't sleep, could you? The type who can't sleep when it's bright? It's written all over your face~"

Was it that obvious? I had noticed pretty dark circles when I looked in the mirror earlier... But to even guess my constitution about not being able to sleep in the light...

"Ah... how did you know?"

"Hehe. A cat who's lived long enough is on the level of a gumiho, you know?"

She winked proudly as she spoke. Then she reached behind her hip, rummaged around, and handed me something. It looked like her business card.

"It seems like you won't be playing at our place today, so I'll tell you about a good one!"

She pointed toward a certain shop.

"Go to that place over there and choose the Eodukshini for the overnight course! Tell them Nago recommended you and they might give you a discount."

Nago... That's what was written on the card she gave me.

"Alright, I'll check it out."

As I started to walk away, Nago waved and added one more thing.

"You have to ask for Eodukshini specifically!"

I gave Nago a light bow and headed deeper inside. When I reached the shop she recommended, the sign above the door caught my eye.

The two keywords that seemed completely mismatched somehow stimulated my curiosity. I wondered if Nago had really recommended a proper place to someone she'd just met, but I figured I had nothing to lose. I cautiously opened the door and stepped inside.

In one corner of the lobby was a sofa and table where guests could rest, and across from it were simple refreshments. It felt just like a motel lobby...

In the center of the lobby was the counter, but strangely, there was no clerk inside. Only a dark space existed there. The lobby itself was bright, yet the area behind the counter was pitch black.

"Welcome~ This is Darkness is Sometimes Warm."

A gentle voice flowed from somewhere. Startled, I looked around frantically before realizing the sound was coming from within the darkness.

"Would you like to rest for a while? Or would you prefer the overnight course?"

A yokai brothel offering overnight courses in broad daylight was a first for me. I'd originally planned to just look around, but since I'd been recommended, I decided to try it out and get some sleep while I was at it.

"I'll take the overnight course. Ah! ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I was recommended by Nago..."

"Ah~ So Nago sent you. Overnight course it is~"

The gentle voice echoing from the darkness sounded pleased when it heard Nago's name.

"We don't let guests choose specific ladies. We use a yokai selection system. Between Eodukshini and Geuseundae, which yokai would you like?"

The choice of two yokai piqued my curiosity, but Nago had strongly insisted I choose Eodukshini, so I set my curiosity aside and picked her.

"Here is your key card~"

A pitch-black hand, as if merged with the darkness, emerged from the shadows, placed the key card on the counter, and vanished back into the dark.

"Go down the hallway on your left. You'll find the changing room and shared shower. Put your clothes in a locker, shower, change into the provided clothes, and then enter your room."

I gave a small nod, paid with my card, and picked up the key card from the counter.

It was an interesting setup. A brothel with a shared shower instead of bathrooms in the rooms... For someone like me who sought out new experiences, this novel structure was incredibly intriguing.

After a quick shower, I put on the gown from the locker room and headed down the hallway to find my assigned room.

I used the key card to open the firmly locked door. Inside was nothing but pitch-black darkness.

Huh...? Is this right?

As I hesitated, wondering if I should step into the darkness or if I'd come to the right place, a voice called out from within.

"Come inside and take off your gown~"

The refreshing voice lured me deeper. I slowly walked into the darkness.

Once inside, I couldn't see anything ahead. With a creak and a thud, the door that had let in the faint light closed by itself. Now I really couldn't see a thing.

It felt like I was alone in a completely black space. A shiver ran down my spine in an instant. It was similar to the eerie feeling I'd had alone in the dark office at dawn.

Feeling that chill, I slipped off my gown. There must be someone here since I'd heard a voice from inside...

Just as I started groping my way forward, something appeared in front of me.

It looked like pure black darkness itself, completely covered in jet black. Strangely, even in this pitch-black room, while it shared the same color as the darkness, its form was clearly visible.

I couldn't see any eyes—whether they were hidden by the black darkness or simply didn't exist—but I could make out a small nose and mouth. She had a skinny, bony body with small breasts and wore no clothes.

Uh...? Wouldn't this... hurt...?

Doing it with such a bony, fleshless woman might feel good in theory, but all the bumping and colliding would surely come with pain.

Maybe my thoughts showed on my face, because the woman—whose scary-looking eyes I couldn't see—smiled with her mouth and approached.

She then grabbed my limp member with both hands and said,

"Not your type? Hehe, but if I do this~"

She stroked it up and down. Of course her figure wasn't my preference, but the physical sensation was unavoidable. Using both hands on my member—which was much larger than her hands—she stroked it several times.

Her body was extremely thin and frail, but her technique was anything but. Those skilled hands were more than enough to stimulate me, and I soon grew hard in response.

"Ugh!"

The intense stimulation made me squeeze my eyes shut. But the more pleasure I felt, the more a sense of guilt slowly crept up from somewhere in my heart. Because of that, I grabbed her hand to stop her movements.

When I slowly opened my eyes, a completely different body was before me. The woman holding my member was now taller than before. Her breasts had grown slightly larger, and her body had filled out with flesh.

Huh...? What is this?

She had grown so tall that her head now reached my chest. She smiled as if finding my reaction amusing and savored my flustered expression.

I took another look at her face. Her previously gaunt face had filled out into a sleek, attractive jawline. Her small breasts had ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠swelled nicely. Her short hair had transformed into long, slightly wavy locks.

Her more mature appearance left me bewildered.

"Why~? Are you surprised?"

She spoke playfully. I nodded without a word.

"Eodukshini are yokai who grow larger the more fear their partner feels. But now that yokai and humans live together in society, there aren't many people who feel fear anymore. So each of us grows according to our partner's specific emotions."

She suddenly grabbed the back of my neck and pulled me down. Then she stood on her tiptoes, brought her lips close to my ear, and whispered.

"Just so you know, I grow when my partner gets excited?"

She released my neck, slowly bent her knees, and lowered her head. Her face stopped in front of my member, and her breath touched my angrily swollen lower half.

Looking up at my face, she said,

"Tell me when it reaches the size you want. I can stop growing whenever."

After hearing her words, I soon felt a warm, moist sensation on my lower body. Looking down, I saw her kneeling as she took my thick member fully into her mouth and began slowly moving her head.

In this pitch-black darkness, the sight of her—black as the void itself—performing fellatio made it look like my member kept disappearing and reappearing.

Slurp. Sluuurp.

Inside her moist mouth, her tongue swirled around my shaft, lovingly caressing every inch. Feeling that warm, soft sensation, I sensed a mass of desire slowly rising from my balls.

I was powerless to stop the eruption triggered by her tongue technique, and I began to release.

"Ugh! I'm coming!"

The thick, sticky fluid forcing its way through the narrow passage sent sensations throughout my body, but she still didn't pull my member out of her mouth. Instead, her suction grew even stronger as she began stroking the exposed part with her hand.

"Ugh!!"

After receiving the pouring liquid in her mouth, she slowly withdrew my member. Then she opened her mouth wide and stuck out her tongue.

My white semen—standing out starkly against her entirely black body—dripped down her tongue.

Gulp.

"Hehe... That was a lot, wasn't it?"

She swallowed the remaining semen on her tongue. Then she slowly straightened her legs and stood up.

Huh? What?

The woman standing tall before me had grown even taller than me. Her breasts had become far more glamorous, and her hips had widened considerably.

How many centimeters...? I was 182 centimeters tall, and now she was as big as a basketball player?

I looked up at her face. Her eyes were still invisible, but her mature, straight nose and slightly smiling lips looked mysteriously sexy.

"Now I've become the big sister, huh? Should I stop here?"

She placed her hands on her hips, tilted her head slightly, and asked. I was curious what would happen if she grew even bigger, and how high the pitch-black ceiling went, but I figured I'd have trouble if she got any larger, so I nodded.

"Good! Hey... you can keep going, right? Come here."

She spread her arms slightly, beckoning me. My lower half was once again standing stiffly at attention, pointing toward the sky.

I slowly approached her and buried my face in her chest as she embraced me. If I stood on my tiptoes, I could see her face up close, but I didn't. Even though her body had grown larger, her waist—when I carefully wrapped my arms around her—was still slender.

She gently held me and laid me down on my back. I had no idea where I was lying since everything was covered in darkness, but it felt somehow cozy.

While I was in her arms, she gently lifted my chin from her chest and pulled me up toward her face. Seen up close, her face was quite mystical.

Her playfully grinning lips had a black tongue slightly poking out. Her straight nose... Where her eyes should be was occupied by deep darkness, but I could picture her expression in my mind.

With a mischievous look, her glossy black lips drew closer and planted a light kiss on my cheek. Then she gazed at me intently before her lips mercilessly covered mine.

Her tongue slipped between my lips and gently caressed mine. I responded by slowly swirling my tongue as well. Our tongues intertwined like our bodies, softly stroking each other.

Then her right hand slipped down my stomach, sliding smoothly downward. She began touching my member with hands as soft as her tongue.

Feeling myself growing harder, I reached out with one hand to caress her breast. I focused on the slightly protruding tip of the dark, full mound, circling it gently or giving it a light tug. Each time, a sweet moan escaped her throat and was swallowed by mine.

"Ahh!! Mmm!"

When I pulled my lips slightly away from hers, a sticky string of saliva stretched between our tongues. Her gradually quickening breaths echoed in the darkness.

"Haa... Haa..."

My fully hardened member below twitched in time with my heartbeat, begging for release. Seeing this, she gave a sly smile, spread her legs in an M-shape, and used both hands to part her faintly visible slit.

"Now... come inside..."

I positioned myself between her M-shaped thighs and looked at her opening. But where she spread it with her fingers, there was no visible hole. It was like a black hole—only a pitch-black abyss.

"Hehe... Hard to see, right? I'll help you..."

She grabbed my thick member with one hand. She carefully aligned it with her entrance, and I thrust my hips forward.

"Hngh!"

Perhaps from the pleasure of my member pushing inside her, she arched her back slightly and let out a moan. I squeezed my eyes shut at the momentary pleasure but slowly pushed my shaft deeper.

Someone in a manga I once read had said it... Darkness pulls everything in... Her black hole-like vagina drew my member in even more strongly. It seemed to wriggle as if begging for more, pulling me deeper inside.

As I slowly thrust in, I felt our hips meet. I began pistoning with increasing speed. Every time I pulled back, her vagina sucked me in as if refusing to let go, urging me toward climax.

"Hngh! Haaang!"

The more intense my hips became, the more intense her moans grew. I felt like I was about to come soon, but her tightly gripping folds still craved my hard shaft, and I didn't want to disappoint.

Carefully controlling the rising urge to climax while moving my hips, she suddenly grabbed my face with both hands. Startled, I stopped moving.

"Hmm~~"

She stared intently at my face as if thinking about something. Then in an instant, she flipped me onto my back on the bed and straddled my hips.

"You must be tired, right? I'll move for you~"

With those words, she lifted her hips slightly, grabbed my shaft with her hand, and aligned it with her opening. Then she slowly lowered herself. A wet squelch sounded as my thick member entered her moist folds.

Was this the power of gravity... or the pulling force of darkness...? Even though it entered slowly, the intense force stimulated my member.

"Ah... Ahhng!"

Her folds tightly gripping my member must have felt pleasure too, because sweet sounds flowed from her lips. Her hips, swaying gently back and forth, were incredibly flexible. Even without intense force, they drew out powerful pleasure.

Squelch. Squelch.

"Ahh... Hngh."

The sounds that carefully slipped from her slightly bitten lower lip were incredibly lewd. Soon she stopped swaying her hips and began bouncing her ass up and down.

The sound of my thighs slapping against her ass echoed through the room. At the same time, she threw her head back and opened her mouth wide.

"Aah! Ahhng! Ugh! So good..!"

Clear saliva dripped from her wide-open mouth, adding a glossy sheen to her dark lips. The warm touch of her hands resting lightly on my chest combined with her increasingly wild hip movements made it impossible for me to hold back any longer.

"Ah... I'm about to..."

"Ahng! Cum inside..."

She dropped down with a smack, and I erupted, spurting thick semen deep inside her.

"Ah..."

"Haa... Haa..."

Still sitting on me, she shifted backward, pulling out the thick member her body had been gripping. From the deep, dark abyss between her legs where my member had been, white fluid flowed out in streams.

She took a rough breath, glanced between her legs, and marveled.

"What the~ That's the second time and you're still coming this much?"

Then she lay down beside me. Spreading her arms, she looked at me and said,

"Aren't you tired? Come here. I'll hold you while you sleep."

Hearing those words, I slowly climbed on top of her and buried my face in her large breasts. Her body, now larger than mine, was as cozy and warm as expected.

Before I knew it, I felt like I was left alone in a space filled entirely with black. My eyes slowly closed as the sleep I'd forgotten came rushing in all at once.

It felt like my body was floating and slowly sinking into an abyss... But it wasn't scary or uncomfortable. Instead, it felt cozy and pleasant.

Ah... So this is what this place is... A place where tired people entrust their bodies to the darkness and heal...

With that thought, I fell asleep.

When I opened my eyes some time later, I was still lying on top of her, warmly embraced. The feeling of her hand gently resting on my head was incredibly warm.

"Haaam~"

Soon she yawned and woke up too. She looked at me and patted my head.

"Did you sleep well? I ended up falling asleep too, hehe."

She smiled softly.

"Hmm... We still have a little time left. Want to do it again?"

I quietly nodded. After several more releases, it was soon time to check out.

She lay spread-eagle with a dazed expression. Thick, pure white fluid flowed from between her legs.

"Haa... Haa... You have great stamina. You really went at it..."

She spoke in a trembling voice. Then she struggled to her feet and gave me a light kiss on the cheek.

"Come again next time~"

When I stepped out of the shop, the sun was shining brightly.

"Ah... It's pretty bright... Well... it'll set again soon..."

I started walking back the way I'd come, heading home. After walking a bit, I saw Nago sitting on the bench again, her two tails swaying as she smoked a cigarette.

When she saw me, she smiled and waved.

"Oppa~! Your face looks so much better now?"

"Thanks to you, I got some good rest... By the way, what kind of yokai are you, Nago?"

I asked her about what I hadn't been able to figure out earlier. Nago grinned mischievously.

"Try guessing~ If you get it right, I might give you something."

"Haha, I'll have to think about it..."

With those words, I promised myself we'd meet again. Nago waved as she saw me off toward home.

My steps on the way home were incredibly light and refreshing. I thought that I should definitely repay Nago later for introducing me to such a healing place. I took her business card out of my pocket and slipped it into my wallet.
