The First Day of the Mission – While Hanging Out with Friends
It was two in the afternoon when I stepped into the lecture hall. Minji, Sua, and Haeun slid into the seats beside me one after another as the professor’s voice began to fill the room. A general education class, followed by a major course. Luckily the four of us shared every lecture, so I was spared the awkwardness of wandering between buildings alone.
I opened my notebook and pretended to take notes, eyes fixed forward. Inside my head, though, a completely different movie was playing. The photos I had taken that morning, the things I had done in the classroom, the moments in the bathroom—they all flickered past like a panorama. The skin between my thighs tingled so sharply that I unconsciously pressed my legs together.
“Ji-soo, are you still feeling sick?”
Sua’s whisper told me my expression had given me away.
“No, the lecture’s just boring.”
I answered with the most ordinary smile I could manage. Sua nodded and turned back toward the board.
When class ended we moved to the next room. Minji chattered energetically down the hallway while Haeun threw in enthusiastic replies. Sua kept the conversation alive with questions. I simply nodded and smiled along. An ordinary university student’s day. Ordinary talk with ordinary friends. Yet something inside me had already begun to fracture.
Before the four o’clock lecture, during the break, Minji spoke up as if she had been holding it in.
“Mondays are seriously the worst. After this, want to head downtown for dinner?”
“I’m in! I’m starving to death,” Haeun answered instantly.
“Me too. What should we eat?” Sua’s eyes sparkled.
Three pairs of eyes turned to me. My heart dropped. The mission I had received in the Twitter replies—masturbate four times a day. I had already done it once in the morning classroom and once in the bathroom. Two more remained before midnight. Factoring in two-hour intervals, I needed to start the next one by ten at the latest.
“Ji-soo? What do you think?”
Pressed by Minji, I had no choice.
“Yeah, sounds good.”
“For real?” Minji’s face brightened. “How about malatang? There’s a new place downtown.”
“Malatang works for me,” Haeun nodded.
If we ate and came back it would be around seven. That would still leave enough time for the two remaining sessions. I calculated silently and felt a wave of relief. It would be fine. Totally doable.
By five o’clock everyone was drained as we left the building. The fatigue from back-to-back lectures hit us all at once. We caught a taxi.
“Downtown, please.”
As soon as the car pulled away, Minji started talking.
“So what have you guys been up to lately?”
“I’ve been looking into Pilates,” Haeun said.
“I’m deep in a drama marathon thanks to YouTube’s algorithm,” Sua added.
While the conversation flowed I stayed quiet. I had nothing to contribute. What I had been doing lately was taking nudes, masturbating, and posting them on Twitter. I could hardly tell my friends that.
“Ji-soo, what about you? Any new interests?” Haeun asked.
“Um… I don’t really know. School eats up all my time.”
I brushed it off and turned to the window. Streetlights were beginning to flicker on one by one.
We reached the malatang restaurant. A bright red sign stood out; the moment we stepped inside, the spicy aroma stung our noses. We took a corner table.
“They say this place is super popular. I saw it on Instar,” Minji said, flipping through the menu.
Even while we ordered and the broth came to a boil, the chatter continued. Haeun talked about a recent movie, Sua brought up the club homecoming, and Minji shared student-council gossip. I nodded and added appropriate comments. When the broth was ready we all picked up our spoons.
“Wow, this is actually amazing.”
“See? I told you it was good.”
The mood grew brighter as we ate. Yet I kept suppressing the hunger inside me. I could feel the texture of my bra beneath the thin T-shirt, the weight of my full breasts beneath that. The panty line under my jeans, the sensitive flesh below it. Every sensation was heightened.
“After dinner let’s go to karaoke,” Minji suggested.
“Yes! Let’s sing something upbeat,” Sua agreed.
“You’re coming too, right, Ji-soo?” Haeun asked.
Another crossroads. Karaoke usually ran past ten. That would make the remaining two sessions uncomfortably tight. Still, refusing now felt impossible. I had already avoided them all weekend.
“Yeah, let’s go.”
After finishing our meal we decided to stop at a café first. Following Minji’s lead, we arrived at the neighborhood’s current hot spot—pretty interior, warm lighting, pure Instar aesthetic.
“The cakes here are gorgeous,” Sua sighed.
The moment the drinks and desserts arrived, everyone pulled out their phones. I did the same out of habit, framing the cake and drink from flattering angles.
“Everyone take a picture? Let’s get one together,” Minji said, producing a selfie stick.
The four of us huddled and smiled. Minji posted it on Instar with tags.
“Ji-soo, you post it too.”
The Instar upload screen waited on my phone. I hesitated. Posting here meant I would also have to upload an exposure shot to Twitter. That was the rule I had set for myself. After a moment I said,
“I’ll be right back from the bathroom.”
“Okay.”
The restroom was tucked around a corner inside the shop, out of sight from the main floor. The wall featured the café logo and soft lighting—the perfect background.
I stopped there. My friends were only a few meters away, just past the corner. The thought alone made my pulse race.
First I would take the Instar photo in my current state. I lifted my phone and smiled as usual, taking several pretty shots while gazing at the lens. The face of an ordinary college student living an ordinary day.
I slipped into the bathroom and locked the door. My reflection looked normal. Just like that morning, I grabbed the hem of my T-shirt and pulled it off, then unhooked my bra. Topless now. I inhaled sharply at the sight of my exposed breasts in the mirror.
I cracked the door open. No one. I stepped out quickly and took the photo in the exact same pose and angle. The expression had to match perfectly. Side by side, the only difference between the two shots should be the presence or absence of clothing.
My heart felt ready to explode. My friends were right around the corner. Anyone could walk by at any second. That tension somehow sharpened the excitement. I wanted to touch myself right there. But I held back. Not yet.
After taking several shots I retreated into the stall again. Still, something felt unfinished. I wanted more. I unbuttoned my jeans, slid the zipper down, and pulled both jeans and panties off. Socks too. Completely naked.
Cold air kissed my skin. The chill of the tiles rose through my bare feet. My whole body felt hypersensitive.
I eased the door open once more and stepped out, standing fully nude in front of the café logo and soft lights. I arranged my face into the same casual, carefree expression I used for Instar photos and smiled at the lens.
Then I heard footsteps. Someone was coming.
My heart nearly stopped. I darted back inside and locked the door, holding my breath. The steps approached, passed the restroom entrance. I was about to exhale in relief when a knock sounded.
Startled into silence, I heard another knock.
“Hello? Is someone in there?” An unfamiliar woman’s voice.
“Yes, I’m here,” I managed.
“Oh, okay.”
The footsteps retreated. It had been dangerously close. My heart still hammered. Yet the thrill that danger brought was stronger than I could have imagined. My hands wouldn’t stop shaking.
I sat on the toilet and checked my phone. The photos filled the screen: clothed, topless, fully naked. Me standing completely bare with an ordinary, everyday smile. The dissonance was strangely beautiful. I chose only the first image for Instar. The rest I would upload to Twitter later tonight.
I dressed again, fixed my hair in the mirror, and smoothed my expression back into that of an ordinary college student.
When I returned to the table Haeun studied my face.
“Ji-soo, your cheeks are kind of red. You okay?”
Shame burned across my skin, but I kept my voice casual.
“Really? The bathroom was a little warm, I guess. It’s nothing.”
“You’ve seemed tired lately,” Minji added with concern.
“I’m fine. Mondays are just rough.”
I sat down and took a bite of cake. Sweetness spread across my tongue, but the hunger inside me remained untouched.
After a little more conversation at the café we headed to karaoke on the third floor. The room had sofas, a table, and drinks. The lights were dim.
“What should we sing? Something fun!”
Minji grabbed the mic and began scrolling through songs. Sua and Haeun did the same. I sat on the sofa sipping my drink.
The dilemma returned. I needed to take care of the next session here. I didn’t know when another chance would appear. Karaoke would likely end after ten, leaving me short on time.
I deliberately spilled my drink on my clothes.
“Ah!”
“Ji-soo, are you all right?” my friends asked, startled.
“Sorry, my bad. I’ll run to the bathroom and clean up.”
“Go ahead.”
I picked up my bag and left. At the end of the hallway was a public restroom. It felt more alien than the one on campus. I entered a stall in the women’s room, locked the door, and let out a breath.
Just like in the student union building bathroom, I would complete another mission here.
I stripped methodically—T-shirt, bra, jeans, panties, socks—hanging each item on the hook. Naked now, the cold air wrapped around me. Unlike the school restroom, this place was silent, empty of any human presence.
I took the selfie stick from my bag, mounted the phone, and hit record. I fixed the stick above the toilet and checked the frame. My naked body filled the screen.
All week I had wanted to record myself masturbating. I couldn’t explain why. I simply needed to.
I closed the toilet lid and sat on it, spreading my legs toward the camera. My full breasts were clearly visible. I cupped them, feeling their soft weight against my palms.
“Hah…”
A moan escaped. Unlike at school, I decided not to hold back here.
My hand slid down my stomach, between my thighs. I was already soaked. My fingers glided along my folds, slick and warm.
“Ah… hah…”
I slipped one finger inside. The tightness welcomed me. I pushed deeper, feeling the walls close around it.
Self-degrading words began to spill from my lips.
“A filthy slut who comes to karaoke with her friends and fingers herself in the bathroom…”
My voice shook, but I didn’t stop.
“No one knows. They’re all out there singing while I’m in here doing this.”
I moved faster. Wet, obscene sounds echoed off the tiles.
“A crazy bitch who wants to get caught… a cheap whore hoping someone walks in and sees me like this…”
I rubbed my inner walls and pressed my thumb against my clit. A jolt raced up my spine.
“Ahng! Hah, hah…”
“Normal girls don’t do this. If they need a man they become perverts who can’t even control themselves…”
My breathing grew ragged. In the mirror I watched myself—naked, legs spread, fingers buried inside while I degraded myself. That was me.
“On the outside I act like an ice beauty, but inside I’m nothing but a whore… ah, ahng…”
I added a second finger. Two now, stretching me, the walls clenching hard.
The words themselves pushed me higher.
“First one in the morning, second in the bathroom during the day, and now the third time already. What kind of slut does this?”
My hips rocked. The wet sounds grew louder.
“Look at these dirty tits… I wear tight clothes on purpose, knowing men will drool over them…”
I squeezed one breast hard. My nipple was rock hard.
“Ahng! Hah, right there, more…”
I found the sensitive spot inside and rubbed it relentlessly.
“I’m just a toilet. Men can use me whenever they want… ah, aaaahng!”
My legs shook. My pelvis lifted, taking the fingers deeper.
“I wish someone would open the door. I wish they’d see me like this and laugh. That would be perfect…”
In my mind the door opened. Eyes filled with contempt and lust stared at me. The fantasy made my insides tighten even more.
“Ah, ahng!”
Climax rushed toward me. My lower belly drew tight. I pumped my fingers as fast as I could.
“I’m coming, ah, aaaaaahng!”
Out of habit the ahegao expression took over my face—eyes rolled back, mouth slack, tongue lolling slightly. My mind went white. Pleasure crashed through every nerve.
“Haa… haa… haa…”
I rode the aftershocks, breathing hard. When I withdrew my fingers they were coated in sticky fluid. I wiped myself with toilet paper, still seated, trying to steady my breathing.
I stopped the recording and checked the phone. There I was—naked, masturbating, calling myself every filthy name. A strange satisfaction bloomed in my chest at the sight.
After finishing the third session of the day, I cleaned up. I wiped my body, dressed, fixed my hair, and composed my face into the mask of an ordinary college student. As if nothing had happened.
When I returned to the room Minji was belting out a song while Sua and Haeun clapped and sang along.
“You’re back. Everything okay?” Sua asked.
“Yeah, I cleaned up. Sorry for the wait.”
“No worries. Sit down. It’s your turn to sing.”
I took the mic with an easy smile and chose a song. An ordinary university student enjoying an ordinary evening with friends. Yet something inside me had already cracked. And I loved that crack. The secret no one else knew, the fact that it made me special. I smiled as I sang—normal on the surface, quietly satisfied underneath. The thrill of this double life was beginning to feel like home.
