.

“You can sleep here.”

“Thank you, Serim Noona.”

“Hehe, sleep well.”

Jin Serim waved goodbye to Kim Doha and immediately headed to her own room.

The room she had given to him was on the 2nd floor of the department store, and Jin Serim’s own room was also on the same floor. They were not far apart.

She drew the curtains, entered the room, buried herself in the blanket, and became lost in thought.

‘It was truly a chaotic day…’

Except for the day of destruction when the zombie virus suddenly appeared, she thought today might have been the most memorable day.

‘What would have happened if I hadn’t called Doha there…?’

Jin Serim had called Kim Doha, who was heading towards Daehwa Station, where the military troops were located.

In this apocalyptic world, bringing in strangers could lead to negative outcomes.

Nevertheless, calling Kim Doha was an act of pure goodwill that flowed from her kind heart.

She wished that no more innocent victims would suffer at the hands of those military thugs.

That choice ultimately became the path to saving all the survivors in the department store.

‘In the end, I only received help from Doha… Is there anything we can do to help them in return…?’

Doha and his girlfriend, Rena, were much more intelligent and powerful than the people in this department store.

Not only were their abilities outstanding, but they were also perfect at planning tactics to predict and overcome the mutant zombies’ attacks.

As the leader that guided the department store, she felt that Kim Doha was an insurmountable wall.

‘Except for the initial unarmed patrol, there were no deaths on our side. If we had fought only with our people, without Doha and Rena’s help…’

Today, it wouldn’t have been strange if all the survivors in the department store had turned into zombies. The mutant zombies were that powerful.

“Sigh…”

Jin Serim let out a heavy sigh.

Her heart felt heavy as a leader who would have to lead hundreds of survivors in the future.

No matter how she thought about it, it seemed difficult for her to become an outstanding leader like Kim Doha.

At that moment, when she was reflecting on the day and about to fall asleep, she suddenly heard a strange noise.

“Slurp… Slurp… Suck…”

‘… What’s that?’

Jin Serim sat up and listened closely.

As a leader, she was responsible for paying attention to incidents that happened there.

As she quietly listened, the sound started to be heard again.

“Slurp… Slurp… Chew…”

‘What… is this noise…?’

It was a sound that seemed somewhat familiar and strangely irritating.

‘It’s like the sound of someone eagerly sucking on ice cream or candy…’

The problem was that it wasn’t a sound that should be heard at this time when everyone was in bed.

‘…I should check it out.’

Jin Serim left the room and walked in the direction of the sound.

“Slurp… Chew… Chomp… Slurp… Slurp…”

The closer she got, the clearer the sound became. It was definitely a sound coming from a human mouth.

The sound of something being eagerly sucked on.

‘It seems like… it’s coming from Doha and Rena’s room…?’

Finally, she arrived at the room they had been given. Outside the room, uninvited guests were huddled together, including Jin Serim—three men and two women. They were all pressing their ears to the curtain of Doha and Rena’s room, holding their breath.

‘Even though I don’t know what’s happening, eavesdropping like this is not polite…!’

Jin Serim approached them and spoke in a low voice.

“Hey, you guys.”

At that, they were startled and turned to look at Jin Serim, putting their index fingers to their lips and frantically gesturing.

If their soundless outcry were translated into refined language, it would be roughly as follows:

“Unnie!? Shh, Shush—!”

“Be quiet, noona—!”

“Noona, you can’t make noise…!”

Having spent a long time with them, Jin Serim immediately understood their meaning and began to communicate using lip movements.

“What’s going on? What happened?”

“……”

They suddenly shut their mouths and began to avoid Jin Serim’s gaze.

Then, the sound came again from inside the room.

“Chomp, slurp, chew…, suck, slurp, chew…, slurp, suck.”

The sound was clearer now that they were right next to it.

Jin Serim looked at them again and asked with her lip movements.

“This is Doha’s room, right? What’s this noise?”

One of the women who understood her question looked at Jin Serim with a perplexed expression and asked.

“Unnie… you don’t know what this sound is…?”

“I’m asking because I don’t know.”

Then, one of the men also asked with the same expression.

“Re, really…? You don’t know this…?”

“You guys… Are you making fun of me?”Jin Serim was secretly short-tempered. In a flash of anger, she opened the door to Kim Doha’s room to uncover the truth.

Of course, there wasn’t actually a door, so by “opening,” she meant she slightly pulled back the curtain.

The scene that was revealed shocked Jin Serim.

“Mmm…, slurp♡, slurp, suck.♡”

“Serena. We’re only doing this once before bed, okay? People can hear us around here if we do this…!”

‘…Gasp!’

Jin Serim quickly returned the curtain she had peeked through to its original position.

Fortunately, the two inside seemed too engrossed in each other to notice.

‘What… What did I just see…?’

It was dark, so she normally wouldn’t be able to see well. However, Jin Serim, who possessed special abilities, saw everything in that darkness.

Two naked bodies entwined, a man’s wide-open legs, a woman’s head buried in his groin, the undulating blonde hair, even the ecstatic expression on their faces.

Even Jin Serim, who was not well-versed in sexual matters, realized it instantly.

This was… oral sex. Also known as fellatio.

‘That sound… like sucking on ice cream…!’

Jin Serim’s face grew hot, and her heart started to beat faster. It was the first time she had seen an actual sexual act between a man and a woman up close.

As she froze after peeking behind the curtain by herself, the five men and women behind her became impatient.

“Unnie! Did you see it? How was it?”

“Is it really happening? Can I see?”

“Noona, can I look too? Can I open it? It’s okay, right?”

Jin Serim snapped to her senses at that moment.

This was an obvious invasion of privacy.

Even if the sound leaked out because the room was not soundproof, that room was assigned to them alone by the department store.

They shouldn’t be peeking like this!

“Hey, you guys! Disperse, disperse! Scatter and go to your rooms! Quickly!”

Naturally, complaints erupted.

“What! Only you get to see!”

“Let us see just once too!”

“You’re stingy, noona!”

Jin Serim took a firm stand.

“Not going away!? You’re making me angry!?”

“……”

In the end, they trudged back to their rooms.

They probably wouldn’t be able to sleep. They could still faintly hear the noise, even from afar.

And so, Jin Serim was left alone in front of Kim Doha’s room.

“Slurp, suck, slurrrrrrp—♡”

“I’m going to start now, Serena!”

“……”

This spot had the best acoustics for hearing the couple’s sexual noises.

‘…I can’t help it. I have to guard this place and control it so that no one sneaks a peek. I’m the leader, after all…’

Even at this moment, Jin Serim’s sense of responsibility was constraining her.

She stood with her arms crossed in front of the curtain like a guardian protecting the couple’s room.

‘Let’s guard them until their relationship ends and they fall asleep. Once they sleep, I’ll return to my room and sleep too…!’

As time went by, more and more people were attracted by the moans of the couple leaking out of their room.

“What’s going on? What’s happening?”

“Surely this… isn’t the sound of sex, is it?”

“Who’s inside? Could it be Doha and Rena?”

“That’s right! It’s sex, isn’t it!”

Each time, Jin Serim would sternly shake her head and speak with her lips.

“Everyone go back. Eavesdropping like this is not polite.”

Of course, protests came back occasionally.

“What about you, noona? Why are you eavesdropping alone?”

“…I am an exception. I have to drive you all away.”

“Hmm……”

“…Go away quickly!”

Thus, Jin Serim guarded the spot alone.

“Ah♡, ah♡, ah♡, I, I’m coming again, Master…♡”

“Heh, I’m coming too. Let’s go together!”

“……”

Moans of climax, countless times.

Every time she heard the noise, Jin Serim’s mind recalled the scene that unfolded before her eyes when she opened the curtain.

Most striking of all was the image of Lena’s face, in ecstasy, as she sucked Doha’s penis.

Her sweat-soaked blonde hair clung to her face, but she paid it no mind and continued to suck as if tasting the most delicious thing in the world…

‘Is that… really that good…?’

Though Jin Serim was a 29-year-old virgin, she had no sexual experience.

As a career-driven woman who had quickly climbed the corporate ladder, she had been so buried in work that she had no time for romance.

‘She really looked happy…’As her thoughts continued, an unexplained ache began to throb in her lower abdomen.

Until then, Jin Serim had been taking it lightly.

‘The sex between the two must be nearing its end soon.’

But.

‘Is sex usually something that takes about an hour…?’

As time went on…

‘It’s taking longer than I thought…’

She had no choice but to admit it.

‘What’s going on? How long are they going to do it…!?’

She realized how naive her thoughts had been…

Thrust♡Thrust♡Thrust♡Thrust♡Thrust♡

“Ma, Master…! Ah♡, Ah♡, Ah♡, Aahh—♡”

“Heh……!”

“……”

Jin Serim pulled out her phone with a dazed expression to check the time.

[12:06]

The sex that had started just after 6 o’clock was still ongoing.

What was even more frightening was that there was still no sign of when it would end.

.

The people in the department store had long woken up.

And the rumors had spread about what was happening inside the room on the second floor where Jin Serim was standing guard.

Now, there was no one among the department store people who didn’t know.

They made a comment each time they passed the second floor, going up or down. Of course, only mouthing the words.

“What’s going on? Are they still doing it?”

“How many hours has it been, this?”

“Wow, Doha’s stamina is impressive. He’s a real man!”

“Why can’t you last as long, oppa, if you’re also capable?”

“……”

“Hey, what time did you bet on for them to finish?”

“I bet on 9 PM.”

“No way, even if he’s strong, 9 PM is too much. Isn’t 6 PM more reasonable?”

Jin Serim, who had witnessed all of this, had to listen to the sounds of the two people having sex for over 10 hours.

“Heh♡, Ahh♡, Again, let’s go…♡”

“Heh…!”

“……”

She was slowly reaching her limit.

‘It’ll be fine to leave for a moment…’

Both her body and mind had truly reached their limit.

Since some time earlier, she had felt a tingling in her lower abdomen that she couldn’t bear.

‘This feeling is strange… Is it a need to relieve myself…?’

As she headed towards the women’s restroom on the second floor of the department store, Jin Serim discovered men lined up in front of it.

“What, what are you guys doing lining up here?”

They answered, awkwardly smiling.

“Ah, the urinals in the men’s restroom are full…”

“There are restrooms on every floor.”

“……They are all full, sister. Don’t worry about it.”

‘All the urinals in the men’s restrooms are in use…?’

Did they all have constipation as a group?

Jin Serim thought it was strange but hurriedly went into the women’s restroom due to the continuing tingling in her lower abdomen.

Sitting on the toilet as she lowered her pants, she was shocked.

“Why, why am I…!?”

Her panties were soaked by something. She hadn’t noticed they were this wet. She must have been incredibly distracted.

She touched the liquid that soaked her panties with her fingertips. It was transparent and sticky to the touch.

This was… unquestionably, her love juice.

“My goodness…!!”

The face of Rena, who she had seen at dawn, sucking Doha’s thick member with a blissful expression, flashed through Jin Serim’s mind. The memory made her vagina twitch and quiver, releasing more love juice.

“Huuh…!”

This was it.

The sensation that had been tingling her lower abdomen since earlier was this.

And it was understandable.

Live sex had continued vividly for more than 10 hours just behind a curtain, and Jin Serim had to listen to it all.

‘Darn it… I have to wipe it off to put my pants back on…!’

She tore some toilet paper and began to wipe off the love juice.

Starting from her wet panties, to her thighs, hips, and lastly, her vagina.

“Heh…♡, Huhh♡, Ahh…♡, Eeeehh…♡”

Jin Serim moaned alone in the restroom, laboriously wiping off all the love juice.

Then, she steeled herself and came out to continue standing guard. To protect the two people’s privacy.

In the end, the sex between the two people didn’t fully end until after 9 PM.

“……Finally…… It’s over……”

Jin Serim’s pants were soaked with her leaking love juice as she finally returned to her room.
