Five Minutes on the Central Staircase Without Underwear

Seo-ah eased the classroom door shut and made her way back to her seat.

The professor went on with the lecture, eyes fixed on the front of the room. A few students had glanced up when the door opened, but by the time she sat down they had all turned back to their screens or their notes.

She set her bag beside the chair, picked up her pen, and looked around once.

No one was paying her any mind. In that classroom, she seemed to be the only person who knew what had just happened.

She tried to take notes again, but the material refused to settle. What snagged her attention first was the simple fact that there was no bra under her knit top. Every small shift brought the fabric straight against her breasts. Sitting upright made it bearable; the moment she changed her posture, she felt it all over again.

She faced forward.

The professor advanced to the next slide.

She meant to write, and then the words she had overheard at the back of the classroom the day before rose up again.

Damn, though. Those tits are fucking pretty.

The tip of her pen stalled.

"…"

She went back to writing as if nothing had happened.

They hadn't even known the woman in the photo was her. It had turned her stomach the first time she heard it, and yet, strangely, it kept lodging in her head. The moment in the hallway just now, when she had bared her breasts, laid itself over the memory.

If that person walking by had seen me, would he have thought the same thing?

Seo-ah shook her head.

Stop. Don't think about it.

She dragged her attention back to the professor.

No new mission arrived before class ended.

For the rest of the day's schedule, she never put the bra back on. At first it bothered her with every step, but as the hours passed it eased a little. Even when she ran into students she knew, no one seemed to notice anything out of the ordinary.

Back at the dormitory, she opened her bag and found the bra exactly where she had stuffed it that morning.

She looked down at it for a moment.

"…I really went the whole day without it."

That morning she never would have imagined spending hours wandering campus braless, and yet nothing in particular had happened. She dropped the bra into her underwear drawer and put the bag in order.

The next morning.

Fresh from the shower, Seo-ah sat on the bed and opened ChatPT.

The first screen displayed Today's Recommended Outfit.

Her eyes stopped at the bottom of the list.

"…Both?"

It wasn't only the bra. The panties were gone too.

She checked the screen again, then opened her underwear drawer. She took out a bra and a pair of panties, one after the other, and set them on the bed.

"What kind of outfit is this."

Beneath the list sat an ordinary little note.

For a while she looked from the screen to the underwear on the bed and back again.

Yesterday came back to her. The recommended outfit had simply left the bra off, and later a mission had arrived demanding she confirm, all over again, that she really wasn't wearing one. The day before that, the panties had already been missing from the recommendation.

She picked up the panties on the bed, then stopped.

If another mission like that comes…

She might have to deal with it at school without warning, the way she had yesterday.

After a brief hesitation, she put both the bra and the panties back in the drawer.

"…If I wait until then to take them off, I might not have enough time."

She shut the drawer.

First she stepped into the navy tennis skirt. The fabric climbed straight over bare skin. Once the zipper was closed, she pulled on the white T-shirt she had bought a few days ago and never worn, dragging it down over her head.

The cloth was thin, but it wasn't a clinging cut. There was a little ease through the chest and waist, and standing square in front of the mirror she looked like any other girl in an ordinary white tee. She turned sideways. Without a bra she was a little different from usual, but it didn't show nearly as much as she had feared.

"…It doesn't show as much as I thought."

The tennis skirt looked perfectly normal from the outside. She checked the mirror one more time, then packed her bag.

Even after she reached campus, nothing about her looked unusual from the outside.

The problem was Seo-ah herself.

Every step let the air under the tennis skirt touch her bare skin directly. A coolness she never would have noticed otherwise brushed the insides of her thighs and the edges of her pussy, and she couldn't stop registering it. Climbing the stairs, she checked more than once whether anyone was coming up behind her.

It wants me to stay like this all day?

No one seemed to have caught on, but she still couldn't relax. By the time her first lecture ended, though, she had grown used to it enough that she no longer froze with every step the way she had at the start.

Class was over. She was slipping her books into her bag when her phone chimed.

Ding.

Seo-ah looked down at the screen.

"…Of course."

She opened the mission window.

Seo-ah read the last condition again.

"It wants me to leave proof on video that I'm not wearing them?"

She really wasn't wearing them. The problem was having to prove it on camera.

She scrolled down.

Her finger stopped.

This time it was her part-time job. Among the contacts filed under #PartTime, there could easily be someone she ran into at the convenience store.

Seo-ah tapped Preview.

The photo appeared, and she closed the window at once.

"…"

A few seconds later she opened it again.

It was a crop from the nude she had registered long ago as a body record, only the lower half. From just beneath her belly down to the tops of her thighs, her pubic hair and her pussy were caught exactly as they were. Almost no face, almost no other identifying feature—it would have been hard to tell the body was hers.

It's still my photo.

She closed the preview.

There was no reason left to doubt that a failure penalty would actually be carried out.

Seo-ah stood.

The landing in front of the 2nd Floor Central Staircase was a little wider than the corridor. A railing ran along where the stairs ended, and beyond it she could look down on the first-floor lobby and the flight coming up from below.

She checked the position marked on the screen. A few students were passing, but no one lingered in ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠one place for long.

She found a spot to prop the phone and lined up the frame. Her whole body and part of the central staircase fit together in the shot. She pressed record.

Seo-ah took her place on the marked spot.

At first, all she had to do was stand there. Literally.

A student came walking from the far end of the corridor and passed in front of her. He might have glanced her way for a second. He kept going.

She checked the phone. Plenty of time left.

"…So for five minutes, I really just have to stand here."

The last verification was the problem, but she wouldn't have to show anything for long. When no one was around, she could lift the skirt and the T-shirt for a moment and drop them again. She made ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠herself believe that.

Then she heard footsteps from the floor below.

Without thinking, she looked past the railing.

A male student was coming up the stairs. He was still a good distance from the second floor, climbing one step at a time from far beneath her. Then he lifted his head.

Seo-ah's gaze dropped, all at once, to her own skirt.

"…Wait."

Even that morning, climbing the stairs, she had worried about whoever might be following behind her. Now she was standing perfectly still at the very top, and he was looking up at her from much farther down.

She looked at the skirt again.

There were no panties under it.

If even a little of the inside of the skirt entered his line of sight, nothing would be there to cover what lay behind the cloth. From where she stood, if he tipped his head up even slightly, he might see straight to her pussy beneath the hem.

On reflex she pressed the front of the skirt flat with her palm. The thin fabric clung to her thighs. Her heart only beat faster.

He kept coming up.

Skirt held down, she tried to keep her eyes forward. Then, unable to stand not knowing how far he had climbed, she looked down once more.

He looked up at the same moment.

Their eyes met.

"…"

For an instant she couldn't breathe.

She had no way of knowing where he had been looking before he raised his head. He might already have seen, before she pressed the skirt down. Or he might have seen nothing at all.

He showed no particular reaction. He simply came up onto the second floor, passed beside her, and disappeared down the corridor.

Only then did Seo-ah loosen the hand clamping her skirt. Her heart did not settle so easily.

…Did he see?

The first thing she wanted was for him not to have seen. Even so, she couldn't stop wondering ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠where his eyes had been.

She stole a glance at the phone. Time still remained.

A little later, two voices rose from below.

This time, the moment she heard footsteps, her hand went to the front of the skirt. One of the two looked up as he climbed, and for a second his eyes met hers. They passed without any particular reaction.

A few seconds later, without quite meaning to, Seo-ah turned to look down the corridor where they had vanished.

…They didn't see. They couldn't have.

The thought brought her face forward again. She didn't really understand, even herself, why she had checked behind her.

After that, whenever footsteps sounded from below, her hand went to the skirt first.

The recording passed five minutes.

She checked her surroundings. The second-floor corridor was empty for the moment. No one was coming up the stairs just yet.

Only the last verification remained.

She caught the hem of the skirt, but her hand didn't move at once. The camera was pointed straight at her. She looked around one more time, then yanked the skirt up fast.

Below her bare belly, her pubic hair and her pussy—nothing covering them—went straight into the frame.

She didn't give herself time to check. She dropped the skirt at once.

"Hah…"

A short breath left her.

Now she only had to confirm the bra.

She took hold of the hem of the white T-shirt. She had done this yesterday too. That thought came first.

She lifted the shirt. Her stomach showed, and a little higher, the undersides of her breasts. At last she rolled the tee up above her chest.

Her breasts, covered by nothing at all, were bare in front of the camera.

In that instant the words from the day before came back.

Damn, though. Those tits are fucking pretty.

Her hand stopped.

"…"

They hadn't known the woman in the photo was her. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠But now her own breasts were sitting, exactly as they were, inside the camera frame.

Seo-ah looked at the phone screen.

When she had lifted the skirt a moment ago, she had dropped it without even thinking of checking. She could do the same now. The fact that she wasn't wearing a bra had already been captured clearly enough.

Her hand still didn't come down.

For a moment she looked at herself on the screen.

…Did I really look like that?

Only after the thought surfaced did she blink.

What am I thinking right now…

Then a voice carried up from the floor below.

"Hey, hurry up."

"I'm coming."

Several sets of footsteps came with it.

Seo-ah startled and yanked the T-shirt down. She dragged the hem into place in a rush and looked toward the stairs. No one was in sight yet, but the voices were getting closer.

She lunged for the phone and stopped the recording. There was no time to review what she had just filmed. She hit submit at once.

A loading indicator spun for a moment.

"Hah…"

Seo-ah picked up the phone.

That was when the students appeared at the bottom of the stairs. She grabbed her bag and walked straight off toward the corridor. Her heart was pounding.

In the women's restroom she locked herself into an empty stall.

The mission was a success. There was no need to watch the video again. Even so, she couldn't stop thinking about how long she had held the T-shirt up at the end.

She opened the clip she had just submitted and pressed play.

At first there was nothing special about it. There she was on the screen, white T-shirt and navy tennis skirt, standing in front of the central staircase. Every time students climbed the stairs, the Seo-ah in the video glanced that way. It was all there. Looking only at the clothes, she seemed perfectly ordinary. From the footage alone, no one could have told she wasn't wearing a single piece of underwear.

She dragged the playhead to the end.

First came the moment she lifted the skirt. The hem rose, and her bare lower body, panties nowhere in sight, entered the frame—then the skirt dropped again almost at once. Seo-ah watched that part pass and pressed her lips together.

Next, her own hand caught the hem of the white tee. The shirt went up. Her bare breasts appeared on screen.

It was different from the skirt. In the video, Seo-ah held the tee above her chest and simply stared at the screen for several seconds, only yanking the shirt down in a panic after the voices rose from below.

She played that stretch again.

"…"

She paused the video.

That was when her breasts on the screen caught her eye. Looking a little closer, her expression changed.

"…What?"

Her nipples were stiff. It wasn't only one of them. Both stood out more sharply than usual.

She brought the phone a little closer. She hadn't misseen it.

"Why are they like this…"

She didn't remember being cold. It hadn't been a place with a strong wind.

Because I was nervous?

She had been on edge the whole time, afraid someone would come. Her heart had been racing. In a situation like that, she told herself, a body could react that way.

She moved to turn the screen off. Then she looked at herself in the video again.

What unsettled her more than the stiff nipples was why, even after the verification was already done, she hadn't lowered the shirt for those few seconds.

She played that part once more.

The line about her breasts being pretty came back again.

Only then did she realize how many times she had rewatched the same stretch.

"…What am I even doing."

She shut the video off at once and laid the phone face-down on her knee. She sat like that for a while, then dragged a hand down her face.

"This is seriously messed up…"

That evening.

Back at the dormitory, Seo-ah set her bag on the bed. She was still in the white T-shirt and navy tennis skirt she had put on that morning. In the end she had spent the entire day, right up until she returned to the dorm, wearing neither a bra nor panties. Even so, no one at school seemed to have noticed.

She set the phone on the desk.

Her reflection showed in the full-length mirror. It didn't look much different from what she had seen that morning. She studied herself for a moment.

Then her gaze stopped.

"…Huh?"
