Chapter 143: Side Story – Modern IF (4)

Chapter 143: Side Story – Modern IF (4)

“Tomorrow is finally vacation…”

“Are you happy?”

“Yeah. I’m super happy. We decided to go to the beach during vacation.”

“Let’s just hang out at my villa. It has a private pool, you know.”

“Uh… Gaeun, you need to enjoy a little romance…”

I slumped over my desk with an incredulous expression.

Gaeun looked at me as if she couldn’t understand.

I smiled faintly at Gaeun.

“Let’s go to the villa later. After we come back from the beach. Is that okay?”

“Well… if Sewon likes it, I don’t mind. We have plenty of time anyway…”

After quickly persuading Gaeun, I slumped back onto my desk.

It’s 7:20 AM, before class even starts.

Yeonseo and Raewon left, saying they were going to the library.

Exams are over, and vacation starts tomorrow, so the atmosphere among the other students was very excited.

Gaeun, who sat down, looked at me blankly.

Then she gently took my hand.

Her subtly upturned lips held so many emotions.

I couldn’t help but blush.

“Ahem, ahem… G-Gaeun-ah, I just thought of something… What are you going to do during vacation?”

I felt like I was going to be overwhelmed by Gaeun’s pace, so I changed the subject.

Gaeun giggled at my words.

Gaeun’s attitude has changed a bit lately.

No, actually, it’s changed a lot.

She’s still a good friend who listens to me, that hasn’t changed.

However, her occasional bold moves sometimes fluster me.

Since the day we were intimate, Gaeun has been teasing me more and more.

It’s not that I dislike it, but it sometimes embarrasses me.

“During vacation? I’m thinking of playing the violin.”

“Oh… Violin? Do you know how to play the violin?”

“I learned a little when I was young. I haven’t played for a few years, but I want to try again.”

“Wow… How long did you play?”

“About 7 years?”

“Th-that’s not a little…”

I slightly opened my mouth at Gaeun’s mysterious experience.

I knew she was talented in many ways, but I didn’t expect her to be able to play the violin.

Her unexpected side made her seem different.

Gaeun chuckled and looked at me.

Then she spoke softly.

“If you’re interested, do you want to come to my place? I’ll teach you a little.”

“Oh, really? Of course, I have to go! I’ve always wanted to try playing the violin.”

“It seems so. You were really captivated by the street performance before.”

Two days ago, I saw a street performance on our way to a restaurant with Gaeun.

Everyone seemed to be in a band, playing violins, guitars, and pianos on the street.

What captured my heart there was the violin melody.

I think I talked about the violin the entire time we ate.

I smiled happily.

“Yeah. Violin is the best… When can I come?”

“Come in about 4 days. My house will be empty then.”

“Come to think of it, this is my first time visiting Gaeun’s house. I’m looking forward to it.”

“It’s nothing special. If you expect too much, you’ll only be disappointed?”

“So what? It’s my first time visiting a friend’s house since elementary school.”

“..Really?”

At my words, Gaeun spoke with slight surprise.

Oops. I got too excited and accidentally said something I shouldn’t have.

I forced a wry smile and closed my mouth.

Teop-

“Are you two still attached today? It’s so sickening.”

Raewon, who had returned from the library, placed something cold on my head.

I wondered what it was and raised my head slightly, and Raewon handed me a strawberry milk.

Behind him, Yeonseo was smiling broadly with her chin resting on Raewon’s head.

“Oh, is this for me?”

“You should move aside, you tall beanpole. Oh, there’s one for you too.”

Raewon said with a slight grumble, but handed the strawberry milk to Gaeun.

Gaeun, who received it, looked slightly bewildered.

“You didn’t have to give it to me. Thank you. I’ll drink it well.”

“Of course. Who’s giving it to you? Now move your chin off my head, you tall beanpole!”

“Heehee.. Raewon’s head smells..”

Yeonseo, dodging Raewon’s slightly angry headbutt, laughed like a pervert.

I chuckled and watched the two bicker.

Although those two bicker every day, they are very close.

In fact, their parents are friends of 20 years.

Should I call them friends chosen by heaven?

Raewon and Yeonseo bickered for a long time and then, seeming tired, sat down next to me.

Raewon wiped away a drop of sweat and sighed.

She fiddled with her hair and then turned her gaze to me.

“By the way… Sewon, why are you here so early? You used to be late with your wife.”

“W-wife..?”

At the word ‘wife,’ my body trembled.

Why am I remembering that time now?

I swallowed and felt my face strangely flush.

Gaeun, who was holding my hand, gave me a suggestive glance.

It’s been about a month since Gaeun and I had sex, but we haven’t had sex again.

Although there were times when her kissing skills improved, making things difficult,

We never went as far as sex.

“..Why are you so surprised? You two are always together. According to Yeonseo, you even live together in a rented apartment.”

“Th-that’s right. Lately… we’ve been together a lot.”

I chuckled and vaguely smoothed over the slightly awkward atmosphere.

Raewon also tilted her head, then lost interest and changed the topic.

We chatted like that, and after the roll call, we took out the textbooks for the next class.

Since exams are over and the essay review is done, we’re not having class.

However, the teacher instructed us to at least take out our textbooks.

It’s incomprehensible, but I have to follow it if I want to watch a movie.

We spent the first period watching a movie, and the second period was hellish outdoor physical education, so I had to change into my gym clothes.

“Ah… Seriously, why do we have to go outside…”

I grumbled softly as I changed clothes.

How nice would it be if we could just watch movies in the classroom with the air conditioning on.

It’s so hot, but the gym teacher insisted on an outdoor class.

He said, ‘If not now, when will you exercise?’

‘Aish, fuck…’

He’s not wrong, but that makes me even more annoyed.

Gaeun gently consoled my slightly sulky mood and slowly led me along.

“Heeu-aaaaah… It’s hottt…”

As expected, the temperature outside the classroom was killer.

Seeing this, I envy Gaeun’s ability to withstand the heat.

I sighed faintly and headed to the playground with Gaeun.

“Okay… Is everyone here? Then I’ll call the roll.”

The bell rang, and the strict, old-fashioned teacher started calling the roll precisely on time.

Even though the sun was shining brightly, the teacher showed no signs of being hot.

If I were hot, I would have whined to go inside.

Despite the cheers of countless students, he didn’t budge an inch.

After calling the roll, the gym teacher, with a stoic face, shouted ‘Free P.E.’

My head spun at that announcement.

As I pondered how to escape this hellish heat, a good idea suddenly struck me.

I tightly held Gaeun’s hand and ran towards the gym teacher.

“Teacher… We want to play dodgeball, can we get a ball from the gym storage?”

“Dodgeball?”

The gym teacher looked at me very suspiciously at my words.

It seems strange that I, who always loafed around with Gaeun during free P.E. time, would be so enthusiastic about physical education.

However, he knew the weather was killer, so he eventually nodded.

“…Alright. Go get it. Don’t slack off.”

“Yes! Let’s go, Gaeun-ah. To get the ball…”

Success.

I was a bit nervous at first, but it’s fortunate that he wasn’t completely devoid of humanity.

I giggled and ran with Gaeun to the gym storage.

“Heeu-aaaaah… I can live now…”

Then, I let out a sigh of relief at the cool gym storage.

“How is it? Feeling a bit better?”

Gaeun looked at me with great satisfaction.

“Yeah. Compared to being out in the sun, it’s heaven…”

The weather today has low humidity and intense sunlight.

Thanks to that, it was quite cool even without much wind.

I smiled faintly and sat on the mattress next to me.

She tapped the spot next to her, as if telling me to sit there.

I sat down on her side with a much better mood.

Then Gaeun tightly held my hand.

“Let’s rest here for a bit. If we’re too late, the teacher will say something again.”

“Let’s stall for 20 minutes. The teacher will understand. We don’t have class anyway, I want to stay here for the full 50 minutes…”

“The teacher will be sad.”

“That’s none of my business. It’s his karma.”

She chuckled at my words and moved closer to me.

Then, something felt a bit strange.

Wait.

I’ve seen this before.

Didn’t we have sex in this kind of atmosphere before, Gaeun and I?

My yuri radar suddenly reacted, and I tried to distance myself slightly,

But Gaeun was already above my head.

“..Sewon-ah.”

“Why, why is it..?”

“..You changed your shampoo. Did you use the one I gave you?”

“Uh-huh.. It smells nice. My hair feels better too..”

“I chose a good one. It matches your preferred scent too.”

Gaeun’s face slowly drew closer.

The scent of roses wafted to my nose, and my heart pounded reflexively.

Gaeun, looking up at me with a smile,

Then, a soft touch touched my cheek.

My face turned bright red, and I felt heat rising.

“Look at me. I’m right here.”

“Uh.. Sorry. That’s-“

Chup.

As I unconsciously turned my face away, Gaeun’s lips ambushed me.

Our lips met and naturally molded together,

And what greeted me was Gaeun’s sweet tongue.

“Mmm.. Hmmm..”

I couldn’t break away even if I tried.

Our tongues intertwined, and our breaths grew ragged.

The teeth that occasionally bumped into each other before no longer did.

We continued the sticky kiss with unparalleled skill.

After passionately mixing our tongues in the dark gym storage,

“Poo-haah.. Haa.. H-here… no… Gaeun-ah..”

I spoke urgently, panting heavily.

The heat was rising, and my head was hazy.

On the other hand, Gaeun showed no signs of stopping.

She grabbed my wrist tightly and laid me on the floor.

My heart was pounding uncontrollably.

“It’s okay. No one will come.”

“What if.. we get caught..”

“I’ll handle it if we do.”

The unfortunate part is that the sense of transgression from doing this in a school is greater than the anxiety of getting caught.

Because of that, I couldn’t resist at all,

And I weakly moaned as I accepted her cool hand sliding under my gym clothes.

Her hand gently pressed my hip and then moved upwards.

Her hand reached under my bra and slowly circled my nipple, making my breath grow more ragged.

“Haa, eut.. Gaeun-ahhh..”

She rubbed my thighs through my gym clothes, increasing my arousal.

She persistently tormented only one nipple, then gently squeezed my erect nipple.

And then slowly rotated her index finger.

A tingling sensation spread from her touch to my lower abdomen.

Although it’s only been a month since we last touched, the pleasure is exceptionally special because I’ve tasted it.

“Heeut, hee-eut..”

I twisted my hips, clamped my legs together, and let out a faint moan.

Gaeun looked at me lovingly and then supported my head,

Leaning my body against the gym storage wall.

“Gaeun-ah.. Let’s, let’s stop here..”

“Shhh..”

Sreuk-

She pursed her lips slightly and then gently inserted her hand into my gym pants.

Then she lifted my underwear and moved her hand to my most sensitive area.

“Heeut, eut.. J-just a m-moment..”

“You’re already wet..?”

It was true.

Gaeun rubbed the sticky entrance of my vulva and then slowly inserted her fingers.

Two fingers entered in an instant.

At the same time, my abdomen contracted, and I gasped for breath.

Chup.

Gaeun kissed my neck, as if to relax my body.

Then she pressed her lips firmly against my neck, and kissed me harder this time.

Her fingers inside me began to move in a circular motion.

So that I wouldn’t feel pain or surprise.

Slowly, and as pleasurably as possible.

And she didn’t stop caressing my neck.

Squish, Squish-

“E-heek, hee-ek.. Gaeun-ah.. J-just a m-moment.. that.. just a m-moment..”

Leaning against the wall, my lower abdomen trembled as I pleaded.

The inside of my vagina was being pressed and rubbed in all the right places, gradually melting away.

Instinctively, I realized from her sucking my neck.

Ah.

I probably got another hickey.

“How is it… Do you like it..?”

“Hickey… You made another one..?”

“Yeah.”

“Don’t.. don’t make them.. I…”

Squelch, Squish-

As I showed my displeasure, her fingers pressed firmly on the upper part of my vagina.

Ah, no.

That’s my favorite spot.

“Hee-eup..!”

I covered my mouth with one hand, barely managing to suppress a moan.

But my trembling lower abdomen didn’t stop,

And I sent a shallow climax through my spine.

“Haak, haak..”

I barely managed to suppress my moans and took a deep breath, tilting my head back.

I don’t know why she knows my weaknesses,

But right now, my vagina was more concerning than such trivial matters.

Chup, suck-

After letting me climax, Gaeun started sucking my neck again.

“Two,” she said, opening her mouth, implying another hickey had formed.

“Hickey.. marks.. to hide.. how.. hard it was.. do you know..?”

“Sorry. The way you try to hide the hickey marks is so cute.”

I don’t know what she finds attractive.

I looked at Gaeun and firmly intended to say ‘Stop,’ but

Jjugeop, jjugeop-

“Hieek, hii-eek..”

As her fingers rubbed my vagina again, I foolishly moaned.

She pressed down on my upper vulva and scratched the vaginal walls with her fingers.

And then, wiggling her fingers, she caressed the inside.

It’s incomparable to masturbation.

Her movements, which seemed to know my body better than I did, made my mind hazy.

Ttubeok, ttubeok-

But.

From outside the gym storage, where I thought no one would come, I heard footsteps.

“G-Gaeun-ah.. J-just a m-moment..”

“..Just a moment.”

Then Gaeun pulled her fingers out and stood up.

I thought I should get up too, but I couldn’t feel any strength in my lower body.

Creak-

As soon as she wiped away the sweat, the gym storage door opened.

There stood Raewon, with a sweaty face.

“R-Raewon-ah? What are you doing here..?”

“You two haven’t come out, so I came to check. Is it that hot? Why are you sweating so much?”

At Raewon’s words, I forced a smile and vaguely replied, ‘Yeah.’

“Yeah. They said it’s very hot. Sewon gets hot easily.”

“That’s true. Yeonseo said the same thing. She told me to check if Sewon’s corpse was in the gym storage.”

“D-don’t say such creepy things..”

I chuckled softly at the absurd story and lowered my head slightly.

Yeonseo sometimes says creepy things.

Anyway, fortunately, Raewon didn’t seem to intend to stay here long.

“Anyway, I’m leaving. You two should come out after a while.”

Raewon glanced at me, roughly checking my condition, and turned away.

Then the gym storage door closed.

“Hoo-aaaaaah..”

I let out a sigh of relief.

Only then did my tension completely release, and my heart pounded wildly.

Gaeun smiled at me.

“It’s quite thrilling, isn’t it?”

“If.. if we had been caught…”

“It’s okay since we weren’t caught. Right?”

“Well, that’s true, but…”

Gaeun’s sly attitude made my head spin.

She smiled faintly and then approached me again.

And then she resumed what she was doing.

She kissed my cheek and then put her hand inside my pants.

At the same time, the corners of her foxy eyes slightly turned up.

“You’re even wetter… Pervert.”

It was true.

I hadn’t realized it before, but my lower body was even wetter.

Perhaps because of that.

Squelch, squelch-

“Haa, haa-ah.. Hat..”

The sensation of her fingers entering my vagina again was even more special.

My lower body was being thrust into at a faster pace, and Gaeun slowly sucked my neck.

She stimulated my sensitive spots with her tongue and pressed the vaginal walls at the timing of my tightening vagina.

Squish, Squish, Squish-

As my breathing grew ragged, she increased the pace of her thrusting.

My body, leaning against the wall, went limp, and a tingling sensation spread upwards.

Her remaining hand dug under my clothes and slowly circled my nipples.

And then, when my lips were also taken,

I surrendered my entire body to Gaeun and trembled my vulva.

‘I think I’m going to…’

As our tongues mingled, my breath grew short.

My head grew hazier and hazier, and the tingling spread throughout my body.

It felt as if my vagina was connected to my heart, as my chest pounded wildly with every thrust.

Gaeun also seemed to realize that I was about to climax.

She gently squeezed and pulled my nipples while roughly thrusting inside my vagina.

The appropriate stimulation and the overwhelming excitement of the gym storage escapade.

Here, in this place.

In a space shared with friends.

Having sex with my best friend, and even letting her touch my vulva.

Along with the thought of being pathetic, an unbearable sense of transgression rose to my throat.

“Heeup, hee.. Eu-hee-eup. Hee.. Hee-eeup..”

I’m about to climax now.

Gaeun’s scent, taste, and her teasing hands that focused only on my weak spots.

Everything was teasing my body,

Squish, sploosh-

“Hee-eup, hee-eup..!”

As my vagina tightened and the upper part of my vagina was pressed firmly,

My back arched forward, and fireworks exploded in my head.

As if everything around me turned white, a tingling and hot pleasure swept through my brain.

Meanwhile, Gaeun didn’t take her lips off mine.

Rather, she kissed me more intensely and persistently than before.

“Hee-eup, hee.. Poo-ha.. Haa.. Hat..”

As I trembled from the aftereffects of the climax, Gaeun took out her wet hand and deliberately flexed and unflexed her index finger.

Sticky, transparent lubrication stretched between her fingers.

To think that came from my body.

Seeing that with my own eyes made my lower abdomen ache even more intensely.

Gaeun, showing the obvious traces, licked her lips and cleaned the lubrication cleanly.

At that stimulating sight, I couldn’t help but swallow.

And then she lowered my gym pants.

Jjueup, jjue-eup-

“J-just a m-moment..!”

She started sucking my vulva, which was covered in lubrication.

It happened so quickly that I couldn’t even react.

She licked the surface with her tongue, stimulated my clitoris with her lips, and then inserted her tongue inside,

Neatly sucking out the evidence of my climax.

“Hoo-ah..”

She wiped her mouth and stood up as if nothing had happened.

She then helped me, who was still trembling and slumped over, to stand up.

And then she whispered softly in my ear.

“Shall we do the rest… tonight..?”

I had no right to refuse.

I leaned against her and gently lay down on the mattress.

My body felt weak from the aftereffects of the climax.

After that, I rested for about 20 more minutes and was able to return to the classroom.

But that day, I was distracted all day by the memory of the sex in the gym storage.

And then, time flew by, and it was time to go home.

“..Let’s go home.”

I swallowed dryly at Gaeun’s words, whispered with my arms crossed.

That night, we ate dinner as usual and had a lot of sex.

Considering that the next day is the vacation ceremony, this is a very good timing.

From then on, our wild physical relationship began.

The thrilling escapade peaked when we went to the beach.

I still can’t forget Gaeun from that time.
