One Irreversible Minute

"Haa… Sunbae… we really shouldn't be doing this."

"What… are we even doing?"

"But if Jeonghun oppa saw me like this… he'd definitely get the wrong idea."

"Jeonghun… he won't be here that soon, will he?"

"What? What do you mean…"

"Jeonghun… he's going to be pretty busy right about now."

Mijin tilted her head at Taeseok's words, completely lost.

That was when Taeseok's hand slid without hesitation beneath her skirt.

The moment she felt his fingers against the soft inner skin of her thigh, Mijin's body jolted as if electricity had shot through her.

"Haah… Sunbae… where is your hand going? Seriously… this isn't okay."

She instinctively grabbed his wrist.

Even with her fingers clamped around his wrist, Taeseok's hand hovered at the edge of her panties—so close it almost brushed the fabric, yet not quite.

Every time she drew breath, her breasts rose and fell softly against him, and sweat-slicked heat passed between their joined hands.

But she could not refuse the electric thrill that radiated ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠from his touch. Her thighs parted of their own accord, and the strength drained from her grip.

"Really… is it that impossible?"

"Hnnngh~ It is. Sunbae… please…"

The hand that had been waiting right in front of her panties climbed higher. This time she could not stop him.

Inside her head she screamed that she had to pull free of his arms, yet the instant his fingertips grazed the elastic edge of her panties, a soft "Haaang…" slipped from her lips.

The soft flesh of her inner thighs clenched and then released, sending a faint warmth into his fingers.

"You're already… wet."

Caught between shame and pleasure, Mijin curled even tighter into herself.

No—she had already collapsed under the pleasure, yet she still clung to a single thread of reason at her fingertips. Watching her like that sent another dark thrill through Taeseok.

"Sunbae… haang… Sunbae… if you keep doing this I… haaang… what am I supposed to do…"

Her face hovered inches from his.

Taeseok cupped her face with one hand.

Mijin turned toward him almost naturally. The moment she realized what he meant to do, she shook her head hard.

"I really can't. Hiiing~"

Her voice trembled, thin as a thread.

Why… why am I like this? I want to kiss this sunbae. I want him to hold me. What is wrong with me…

Anxiety and shame swam in her eyes, but the deep flush on her cheeks and the ragged rhythm of her breathing made no effort to hide her lust.

Just as she expected, his lips drew closer.

"Sunbae, please… mmmph…"

Experience had already taught her: once the emotion ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠value climbed past thirty, her body would no longer be able to refuse him.

Before the last syllable left her mouth, Taeseok's lips claimed hers completely.

"Mmm…!"

Mijin flinched for a heartbeat, but she did not pull away.

The instant their mouths met she locked both arms around his neck and sank deeper into the kiss of her own free will.

Her tongue was even more aggressive than his—sliding into his mouth, hunting his tongue, licking and sucking as if starved.

Sweet, wet saliva mixed between them.

One of Taeseok's hands slipped beneath her blouse and closed hard around the soft, resilient swell of her breast. Every time his fingers sank deep into the flesh and kneaded, Mijin's body gave a small, helpless convulsion.

"Haang…!"

Still kissing him, she pressed herself tighter against his chest, breathing in short, frantic bursts.

So this is the kind of chest Mijin has been hiding…

As he groped her, Taeseok painted a mental picture from pure sensation alone. Her breast changed shape inside his grip, crushed and reshaped; the stiff nipple tried to escape between his fingers, hypersensitive.

Shame kept her eyes squeezed shut, yet her hips rolled forward and back on their own, grinding against the hard length straining under his clothes.

Taeseok pinched her nipple between thumb and forefinger and deepened the kiss, rougher now. The moans leaking from Mijin's mouth grew sweeter, wetter.

Then the heat of something pressing against her ass climbed her spine and made the nape of her neck tighten.

"Mmm… haa… Sunbae…"

Before she knew it his hand was under her skirt again, slowly dragging her thin panties down to mid-thigh.

"Sunbae… you're not… right? You're not that kind of person."

Taeseok nipped her earlobe and whispered in a low voice.

"Okay… if you don't want it… I won't."

With the panties gone, the heat beneath her ass became unmistakably clear.

It was both familiar and completely new. She knew it had to be a man's cock, yet its length and thickness far exceeded anything her imagination had ever sketched as "normal."

She heard the soft rasp of Taeseok's sweatpants being shoved down to his knees.

He guided one of her legs over so that her thigh wrapped around his waist. Her bare pussy settled directly onto his cock.

"Haaah~ What even is this… hnnngh…"

The moment his hot, rigid cock dragged a long, slow stroke along her soft folds, pleasure she had never known exploded through her body.

He still had not entered her, yet the sensation of that thick shaft sliding against her pussy was on an entirely different level from everything that had come before.

"Hnnngh… it's so… hot…"

Her pussy began to itch—the kind of maddening tickle you can't scratch, or rather the kind you desperately want to scratch knowing that the second you do, everything will fall apart.

She clenched her teeth, trying to swallow the moans, but her hips moved on their own, searching for more of him.

She wanted him inside so badly she thought she might lose her mind.

"Sunbae… not there. Don't put ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠it in."

Anyone listening would have heard the words as a plea of "please put it in," not a refusal.

But Taeseok obeyed her words. He did not push inside.

His glans parted her soft lips and rubbed over her clit; the thick shaft dragged along her entire slit—yet he never crossed the final line.

That restraint drove her even crazier.

"Sunbae… haaang~ Sunbae… I… I think I'm going to lose it. What do I do…"

"I think I'm going to lose it too."

Taeseok's voice had gone rough.

"I'm trying so damn hard not to put it in. Your pussy is… so wet and slippery and it feels so fucking good… holding back like this is actual hell."

Mijin shook her head.

You idiot… if it's that hard, just put it in!

She wanted to scream the words, but they stayed locked behind her teeth. Her hips only ground more obscenely against him.

Every time she dragged her soaked folds along that massive column, wet, lewd sounds filled the space between them.

"Ahang~ Ahang~"

Please put it in. I'm going crazy. I don't care that you're my boyfriend's friend—why would you get me like this and then…

Her thighs trembled violently; her pussy clenched again and again, trying to suck him in.

"You really… can't put it in."

She kept making him promise, yet the subtext screamed, You're still not going to put it in even after all this?

At last Taeseok brought his lips to her ear.

"Is it really not okay? Just once—can't I put it in just once?"

"!!!"

The moment she heard those words, Mijin understood they were exactly what she had been dying to hear.

"Mijin… just one minute. I'm… suffering right now. I won't move. I promise."

It was pure bullshit.

The second he went inside, one minute would never be enough. And the promise not to move was even more of a joke.

They both knew it.

Yet right now those words worked on her. She was almost grateful he had said them—because it meant she only had to share half the responsibility.

"Then… only one minute."

"Yeah… one minute."

"Just putting it in. No moving."

"Mm. Just putting it in…"

Mijin closed her eyes. She held her breath. And she waited.

"Okay. I'll stay like this. If you… lift your hips just a little, I can put it in."

She gritted her teeth. Shock and the silent question I have to do it myself? flickered across her face.

But Taeseok remained perfectly still, waiting for her next move.

"God, Sunbae…"

The rest of the sentence died. Her soaked pussy was already begging for him.

Mijin bit down hard. One hand braced on his shoulder, the other clamped over her own mouth, she slowly lifted her hips.

Her lower belly tensed; the entrance of her pussy parted a little wider. She guided the scorching head of his cock to her opening herself.

"Haa… haa… really… only one minute."

Eyes squeezed shut, she lowered herself by agonizing degrees.

"Uuuuh…!"

The instant his glans forced her narrow entrance open, Mijin's back arched like a drawn bow. His cock was thicker and hotter than she had imagined.

One inch, two… every slow push deeper forced her walls wide, flooding her with crushing pressure and explosive pleasure at the same time. She could not even make a proper sound; the air locked in her lungs.

"Ah! Ah~ It's too… big… all of it… it won't all go in… it's still not all the way, right?"

"Yeah. Not even halfway."

The sheer girth was overwhelming; the sensation of being completely filled blanked her mind white.

She lowered her hips further until she had swallowed every last inch of him to the root.

"Hnnngh…!"

The moment he bottomed out, her whole body convulsed hard. She was stunned that she could be this full.

Her pussy clamped and fluttered around Taeseok's cock; overflowing juices soaked his thighs. She buried her face against his shoulder and shook violently.

"Sunbae… it's so… deep… I'm so full inside I… I think I'm going crazy…"

She tried to lift her hips a fraction and sink back down, but Taeseok's hands locked around her ass and stopped her cold.

"Don't move. If you do, I won't be able to hold back either. We promised… just one minute like this."

Mijin shook her head in disbelief.

"It's already in… what does that even matter now?"

"I don't know either… but I feel like we have to. You're… my friend's girlfriend, after all."

Taeseok knew perfectly well how ridiculous he sounded. He simply wanted it this way.

He wanted to watch the girl he had liked for so long move on him of her own free will. Even if she didn't, he wanted to torment her until she came crawling back. That, he believed, would make Jeonghun—who had so casually tossed his own girlfriend in front of him—regret it even more.

Still pressed against his chest, Mijin begged in a tiny voice.

"Okay. Fine. We'll just stay like this. Then… we didn't really do anything."

Was bullshit contagious?

She had put his cock inside herself with her own hands and was still claiming they had done nothing. She needed a loophole so she could keep lying to herself about what she was doing with another man while she still had a boyfriend.

She rocked her hips forward and back the smallest possible amount. Even that tiny movement dragged his cock across her most sensitive places and sent sharp spikes of pleasure through her. She swallowed moans and trembled, holding her breath until her chest swelled and a tiny, tearful sound escaped anyway.

It feels this good just from that little bit of movement… why do we have to do it this way? This is… torture.

The promise not to move and the raw desire to move crashed inside her body. She still did not understand why she was fighting so hard to keep a promise that had been absurd from the start—yet she kept fighting.

She hugged his neck tighter. The harder she pulled, the deeper he sank. And the one-minute mark had already passed a long time ago.
