Mission Day Two: Self-Introduction in an Empty Classroom

The clock struck five in the afternoon. As soon as the final lecture ended, the classroom erupted into a chaotic symphony of scraping chairs, rustling bags, and lively chatter about dinner plans.

I packed my things and walked out into the hallway with Minji, Sua, and Haeun.

“That class was seriously boring today,” Haeun said with a yawn.

“Right? How do they even fill three whole hours?” Minji nodded in agreement.

Sua turned to me. “Hey Jisoo, want to grab dinner together? I heard there’s a new pasta place right outside campus.”

I swallowed hard. Four times a day. Two sessions still remained.

If I went to dinner with my friends now and returned obediently to the dormitory, I had no idea when I would manage today’s remaining missions.

Besides, barely an hour had passed since I had done that insane stunt—walking around the men’s bathroom completely naked. The memory sent a shiver racing down my spine.

The excitement from that moment still lingered inside my body.

“I… actually don’t have much of an appetite right now.”

I tried to sound as casual as possible.

Haeun nodded. “You did look a little off during class earlier.”

“It’s just… my stomach feels a bit upset.”

I added the lie without missing a beat.

“Really? Do you have any medicine?” Sua asked, her voice full of concern.

“Yeah, I’m okay. I think I just need some rest.”

Minji patted my shoulder gently. “Then get some good rest. See you in class tomorrow.”

Avoiding their eyes, I turned and headed in the opposite direction.

Behind me, I could hear my friends laughing, but I didn’t look back.

The moment I was alone, my pace quickened. My steps toward the library grew faster and faster.

As usual, I climbed to the second-floor reading room.

I took deep breaths as I ascended the stairs.

Around this time, I would normally be studying here by myself.

Since midterms had only just ended, I figured there wouldn’t be many people around.

When I opened the reading room door, a cool draft brushed across my face.

My usual spot by the window was empty.

Out of habit, I set my bag on the chair and glanced around.

There were fewer students than I expected.

A handful of people sat scattered throughout the room, each absorbed in their laptops or books.

But it wasn’t completely deserted. Heads were visible here and there, and the occasional sound of turning pages broke the silence.

There aren’t many people…

The moment that thought crossed my mind, I was shocked at myself.

Instead of feeling relieved that there were so few people, I actually felt disappointed.

I really was crazy. Like some kind of exhibitionist, I was craving a more dangerous situation.

I grabbed my bag again. I decided to check the third floor.

My heart pounded as I climbed the stairs. Third floor, fourth, fifth… I wandered through each level.

There weren’t crowds on any floor, but none were completely empty either.

It looked like I’d have to wait until late at night for the place to clear out.

The library might be too risky.

I went back down to the second floor, retrieved my bag, and left the building with a sigh.

It would have been so easy to just masturbate in the women’s bathroom and complete the mission.

Inside a locked stall, I could have done it safely, without any danger at all.

But I couldn’t bring myself to do that. A safe choice wasn’t what I wanted.

A wave of regret washed over me. I should have just done it in the women’s bathroom. The thought kept circling in my head.

Still, I pulled myself together. I would push myself as far as I could go.

The more dangerous it was, the more excited I became. That was exactly what I wanted.

I left the library and wandered around campus. I had nowhere to go.

It was still too early to return to the dormitory, and every café was packed with people.

Then, suddenly, I remembered the lecture hall where my afternoon class had ended.

Humanities Hall, Classroom 302.

Since all the day’s classes were over, it should be empty.

At six in the evening, I stood in front of the Humanities Hall.

A few classrooms inside the building still had their lights on.

The moment I opened the entrance door, the security office came into view.

No one was inside. A note was taped to the door.

One hour until seven. A wave of relief washed over me.

If the security guard was gone, no one would suspect anything.

My steps toward Classroom 302 felt light.

I paused briefly in front of the lecture hall door.

If someone asked what I was doing, I could just say I’d left something behind.

I took a deep breath and opened the door.

The classroom was empty.

Because it was a large lecture hall, my footsteps echoed loudly.

The tiered seating could hold over two hundred people.

I flipped the light switch. The fluorescent lights flickered on all at once, flooding the room with brightness.

I walked up to the podium.

Standing there, I could see every single seat in the hall.

The empty chairs seemed to be staring back at me.

It felt like a stage prepared just for me.

My heart began to race.

I noticed a CCTV camera mounted in the corner of the ceiling.

But since the security office was empty, they probably wouldn’t bother checking the footage.

That was how I rationalized it.

In fact, the very existence of the camera excited me even more.

The possibility that someone might watch—this thought set my body on fire.

Simply masturbating felt like a waste of such a perfect stage.

I wanted to do something even more special.

I set my bag on a nearby seat and took out my tripod.

I mounted my phone, then walked down to the middle of the seating area.

I positioned the tripod in the aisle and checked the screen.

The podium appeared slightly magnified.

I pressed the record button.

A red light began to blink.

I stepped away from the tripod and walked back to the podium.

My footsteps echoed throughout the empty hall.

Standing on the podium, I looked at my phone.

The small lens stared back at me.

I took a deep breath. Then I lowered my head slightly and began my greeting.

“Hello.”

My voice rang out in the empty classroom.

It sounded louder than I expected.

Because I had placed the camera in the middle of the seats, I deliberately spoke louder so the audio would record clearly.

“My name is Kim Ji-soo. I’m twenty years old, a first-year Humanities student. My student ID number is 2.....”

The fact that I was revealing my personal information in an empty lecture hall strangely turned me on. My voice trembled slightly.

“My close friends are Minji, Sua, and Haeun. My roommate is Sumin. Everyone thinks I’m a good, well-behaved girl. I always sit in the front row during class and I’m the kind of model student who answers the professor’s questions perfectly.”

I paused for a moment and looked straight at the camera.

A smile spread across my lips.

“But that’s all fake. My real self… is completely different.”

My heart pounded so hard it felt like it would burst.

The things I was saying were becoming more and more dangerous.

“I post my photos on Twitter. Sometimes edited ones, sometimes real ones. Men leave comments after looking at my pictures, and I get aroused reading them. When I read words like ‘cumdump,’ ‘whore,’ ‘bitch in heat,’ my pussy gets wet.”

My quiet voice echoed through the lecture hall.

Even saying my friends’ names excited me.

What kind of faces would they make if they ever saw this video?

Just imagining it sent a shiver of pleasure down my spine.

“Today, during class, I went to the men’s bathroom and masturbated completely naked. I even walked around the hallway naked. I really am a crazy bitch, aren’t I?”

I slowly began unbuttoning my blouse.

One button at a time. The white fabric parted to reveal my breasts.

My full, bra-covered breasts appeared on camera.

“A pervert doesn’t need clothes, right?”

I completely removed the blouse and let it drop to the floor.

I unhooked the back of my bra.

The straps slid off my shoulders, and the bra fell to the ground.

My breasts bounced out with elastic firmness.

My nipples were already rock hard.

I loosened the waistband of my skirt and let it slide down my legs.

The thin fabric slipped down, leaving me in nothing but my panties.

The lewd curve of my mound was visible through the white cotton.

“Even now, my pussy is soaked with excitement. This bitch in heat is going to start masturbating.”

I pulled off my panties. I was now completely naked.

The cool air wrapped around my bare skin.

I sat down on the cold floor of the podium.

I spread my legs.

One hand moved between my thighs.

I was already soaking wet.

My fingers traced the slick folds.

“Ah…”

A moan slipped between my lips.

I slid my middle finger inside.

The warm, wet interior clenched around my finger.

“I wasn’t always like this. I wanted to live a normal, ordinary life… but at some point, I changed.”

I moved my finger slowly.

My juices coated my finger.

“Ah… I don’t even know when it started. I just… get excited in dangerous situations. The thought that I might get caught makes my pussy drip.”

With my other hand, I pinched my nipple.

A sharp jolt of pleasure shot from my breast straight to my brain.

“Mmm…”

“My friends don’t know anything about this.

Minji is famous for knowing everything, but she has no idea I do things like this. Neither do Haeun or Sua…”

My fingers moved faster.

Wet, squelching sounds filled the lecture hall.

“Ah… if my friends ever found out… what would they think… just imagining it makes me even wetter…”

I pushed both my index and middle fingers inside.

My pussy clenched tightly around them.

“Haa… I really am a pervert. At school, in lecture halls, in bathrooms… I touch my pussy anywhere. I’ve even gone into the men’s bathroom, walked around naked…”

I rubbed my clit with my thumb.

A wave of ecstasy rippled through my body.

“Aaaah… right there… it feels so good…”

Orgasm was approaching. My legs began to tremble.

Juices flowed from my pussy and pooled on the floor.

“I… watch people insult my photos on Twitter. I masturbate while reading those comments.”

“Ah… I’m coming… I’m really coming…”

“This crazy bitch is reaching climax right now… haaaaaah!”

My body shook. My pussy convulsed, gripping my fingers.

White fluid leaked out between them. My breath caught in my throat. Everything went white.

“Haa… haa…”

The aftershocks rippled through me.

The cold floor of the podium pressed against my buttocks.

My sweat-covered body felt chilled.

I smiled at the camera, my face flushed red.

I collected myself and walked back to the tripod.

I stopped the recording.

The saved video appeared on my phone screen.

It looked like it was about fifteen minutes long.

I went back down to the podium and got dressed.

I buttoned my blouse and pulled on my skirt.

I stuffed my bra and panties into ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠my bag. As I straightened my clothes—

The classroom door suddenly burst open.

“Huh? Is someone in here?”

The security guard stepped inside.

He stared at me with a surprised expression.

My heart nearly stopped.

But I forced myself to stay calm and answered as naturally as I could.

“Oh, I left something behind earlier, so I came back for it. I was just about to leave.”

The guard looked ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠at me suspiciously.

His eyes scanned the bag in my hand and my slightly disheveled clothes.

“Why are all the lights on?”

“Sorry? Oh, it was dark. I needed to see.”

“I see…”

“Yes, I understand.”

I gave a quick bow and practically fled the classroom.

The moment I stepped into the hallway, my heart pounded like it would explode. My legs were shaking.

What if the guard thought something was off and decided to check the CCTV?

The thought terrified me.

But at the same time, for some strange reason, it excited me even more.

The possibility that someone might see me masturbating naked—it set my body on fire again.

“I really am crazy… if I get caught, it’s all over…”

I muttered to myself in self-deprecation.

Yet a smile played on my lips.

Since I hadn’t eaten dinner, my stomach was growling. I headed toward the convenience store.

I felt a sense of accomplishment for successfully completing this mission.

I had barely escaped being caught by the security guard and had even finished my third masturbation mission of the day.

One more ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠still remained. But for now, I needed to fill my stomach.

The bright lights of the convenience store appeared ahead.

I adjusted my bag and quickened my pace.

Inside my bag was my phone, and inside my phone was the video I had just recorded.

I wondered what would happen if I uploaded it to Twitter.

The video would spread. Eventually, my friends and family might see it.

Just imagining that made my pussy grow wet again.

The automatic doors of the convenience store slid open.

I let out a long sigh and stepped inside.
