Chapter 150: Side Story – Modern IF (11)

“Are you crazy?”

I was the first one to speak.

Gaeun scratched her cheek with a slightly awkward expression and shook her head.

“No… Sewon-ah. It’s not like… I have any weird intentions. Listen to me, okay?”

When I gave her a slightly cold look, Gaeun fidgeted and held my hand tightly.

The other two chuckled as if they found it amusing.

It felt a bit like a husband controlled by his wife.

I pretended to be a little upset and looked at Gaeun.

Eventually, I couldn’t hold back and burst into laughter.

“I’m not angry. What are you trying to do?”

“We’re going to switch partners and have sex.”

“Can I be angry?”

“No… Calm down. Wouldn’t it be fun? We’re not complete strangers, after all.”

“Hmm…”

Even at the shocking word ‘swapping,’ Raewon and Yeonseo didn’t show any signs of finding it strange.

Perhaps it was because Yeonseo’s mind was a flower garden.

Anyway, where did she learn about swapping?

“Where on earth did you see something like that…?”

“..Just skip the source. Sewon, you’re also interested in various plays lately, aren’t you? Wouldn’t it be okay to try it?”

“Um… That’s true, but…”

I’ve been researching various things, even searching online, because of our play.

It wasn’t that I was tired of sex with Gaeun.

On the contrary, because I was so satisfied every day, my eyes were drawn to even more diverse pleasures.

Swapping was one of them.

It was strangely curious.

What kind of voices would Yeonseo and Raewon make when having sex?

I was also curious how Gaeun, who always attacked me, would react when being attacked.

That perverse curiosity seemed to have made my expression strange.

Gaeun smiled faintly as she looked at me.

“Sewon, you’re intrigued too, right? Let’s just do it once today. Okay? Sewon-ah…”

Then, she pleaded with me with pleading eyes.

Whenever she really wanted something, Gaeun would beg me with this look.

This usually happened when we were doing cosplay, bondage, or bizarre equipment play.

“..What about you guys?”

Without answering, I looked at Yeonseo and Raewon.

Gaeun seemed to have taken my silence as ‘tacit consent.’

Her expression was beaming.

Yeonseo seemed to be contemplating for a moment, then gently stroked Raewon’s face.

Her hand moved down her neck to her shoulder.

For some reason, her hand went inside her clothes.

She seemed to be massaging something, then withdrew her hand.

As she kept fiddling with it, Raewon shivered.

She threw her head back and exhaled heavily.

Then, she answered in a delicate voice, ‘I’ll do it…’

‘Is this right…?’

It felt like she was being coerced.

But since she said she would do it, it should be fine, right?

Feeling my mind go blank, I looked at Yeonseo.

“Since Raewon is doing it… I guess I have no choice but to do it too…”

She was attempting some nonsensical acting.

In any case, this means all four of us agreed to swapping.

I swallowed hard and stared intently at Gaeun’s face.

“So… what do we do now?”

“We have to switch people. So, um… let’s each choose someone, and the people chosen by both sides will pair up.”

So, Gaeun’s suggestion was to swap with people we felt a connection with.

I nodded. It wasn’t a bad method.

“Then… let’s start. One, two, three.”

The nominations began, and I fell into a brief contemplation of whom to choose.

Although the nomination itself was quick due to the method.

The person I nominated was Raewon.

Whether it was good luck or bad luck, Raewon also nominated me.

The remaining were Gaeun and Yeonseo, and they also nominated each other.

It’s so strange. Could it really happen like this, even by coincidence?

“I’ve thought about wanting to ruin that proud face at least once… Hehe…”

Yeonseo, who nominated Gaeun, made a rather dangerous remark.

When the switch was flipped, her eyes completely changed.

It was like a predator, but also like a perverted degenerate.

Gaeun also seemed to notice something strange and frowned slightly.

I couldn’t easily imagine the situation of her attacking Raewon due to her usual image.

But seeing that, I got the gist of it.

“Um… then, when should we start? Should we… wash up first?”

I changed the subject somewhat due to that eerily creepy sight.

Gaeun nodded at my words.

They must have had sex and showered today, so it didn’t matter to them.

But not to us.

Gaeun and I got up and took a quick shower.

After showering and drying our hair, Yeonseo and Raewon were waiting for us on the bed.

“..Shall we start?”

“Uh, un…”

The owner of the room wanted to do it on the bed, so we laid out a soft mat.

I wondered if we had to do it in the same room.

The remaining bed was Yeonseo’s parents’ bed, and I felt that was a bit much.

“Hoo…”

I sat down gently on the mat and looked at Raewon, letting out a small sigh.

Since she had changed into comfortable clothes, her skin was slightly exposed.

To be doing this with a friend I see every morning.

My heart pounded wildly with a strange sense of depravity and inexplicable guilt.

Gaeun was also a friend until recently, so maybe it’s okay?

Rationalizing it to myself, I slowly started to take off my clothes.

‘Her face is so red…’

It seemed I wasn’t the only one feeling strange; Raewon also had a peculiar expression.

Her appearance was quite cute, so I gently stroked her shoulder.

Seen like this, she’s so small.

Her face, shoulders, and delicate arms.

Her slightly full chest was the only thing that showed a weak presence.

I moved my hand from her shoulder to her face and said softly.

“…I’ll start now.”

“Uh, un…”

This is bad. It’s so awkward, it’s hard to set the mood.

Was the swapping too sudden?

While we were in that awkward atmosphere.

“Ahah… Hah…”

Yeonseo’s voice began to be heard from the bed.

At first, it was a laugh mixed with a slight tickle, but her voice gradually melted into it.

Gaeun is really good at caressing.

Thanks to that voice, the reality of having sex felt palpable.

Slurp.

Right. There’s no need to be awkward.

I should just do it like usual.

I kissed Raewon’s neck briefly and gently laid her down.

Then, I stroked her slightly soft belly with my hand.

Kissed her pubic bone again and slowly moved up towards her chest.

Rustle-

As I removed the clothes that were barely hanging on, the evidence of her arousal appeared.

‘Her nipples are a bit big…’

Indeed, they were different from Gaeun’s.

But it didn’t seem ugly or anything.

Rather, with their pretty pink color and shape, they felt even more alluring.

“Wh-what are you doing… If you’re going to do it, do it quickly…”

Was I staring too intently at her nipples?

Raewon frowned slightly and spoke in a displeased voice.

Judging by her slightly rough breathing, she seemed very excited.

I nodded and poked her erect nipple.

“Hoot, ooh…”

Immediately, a voice came out.

I kissed her abdomen repeatedly, then kissed her areola again.

“Whyyy… everyone… when they see me… can’t stop bothering my nipples…”

Judging by her reaction, Yeonseo’s nipples were also bothered a lot.

After all, she attacked her chest when getting an answer earlier.

‘This is the weak spot…’

Since she revealed her weakness herself, it’s only polite to exploit it.

I gently licked her areola in a circle, then lightly bit the tip of her nipple with my teeth.

Raewon shivered but didn’t seem to be in much pain, exhaling breath.

Since she just showered, she smelled nice like soap.

Using my teeth, I gently rubbed it with my tongue.

Then, I sucked that part vigorously.

“Hoo, ahh…”

The stimulation was so strong that I felt her body jump slightly.

I held her small hands with both of mine and brought my knees between her legs.

Clasping our hands, I sucked her breasts, feeling her lower body getting wet.

‘She’s getting wet so fast…?’

What did she do to have such high sensitivity?

She must have been developed in areas I don’t know about.

Thinking about it, I truly realized how perverted Yeonseo was.

After bothering her nipples for a long time, I finally let go.

“Heek, heek…”

Raewon turned her head away, perhaps embarrassed by my caresses.

She tried to cover her face several times.

But why would I have held her hands and caressed her for no reason?

The completely melted expression of the once strong Raewon was a different kind of stimulation.

Her mouth, which had been spewing vulgarities, was now letting out moans, and her dry body was drenched in arousal.

‘She’s driving me crazy…’

I stroked her hair with my hand, then lightly kissed her cheek.

My lips, which touched her soft cheek, naturally reached her lips.

I gently inserted my tongue and tapped her neat teeth.

At the same time, her lips trembled.

Her breathing was a bit strange, so I pulled away from the kiss.

“Hooa… What’s wrong?”

“You, you… why did you kiss me all of a sudden…”

“Huh? What’s wrong? Of course, we’re going to have sex, so a kiss is…”

Raewon’s reaction is unusual.

She frowned and touched her lips with her finger.

Wondering what was wrong, I looked at her, and Yeonseo, who was enjoying herself, spoke.

“She… hasn’t kissed anyone but me…!”

Sploosh-

Along with a moaning voice, a strong fountain poured onto the bed.

Gaeun smiled faintly as she looked down at Yeonseo, who was writhing and panting.

“She has good sensitivity. When do you use the dildo?”

“Ev-every day…”

“Hmm… Really? Can you do fisting too? Since the dildo is that size…”

Some dangerous remarks were flying around.

I decided to ignore them and turned my attention to Raewon, who had a few tears welling up in her eyes.

It seemed she considered kissing someone other than Yeonseo as a form of ‘cheating.’

‘Should I have asked first…?’

Actually, that’s a bit of a gray area.

I’m the type to just go for it when kissing.

Feeling a slight sense of guilt, I hugged Raewon tightly.

“…I’m sorry. I didn’t know. I thought kissing was okay since swapping was okay.”

I whispered softly in her ear and stroked her hair.

Then, Raewon’s breathing gradually became more relaxed, and I could feel her tension easing.

Once she had completely calmed down.

I looked directly at Raewon and smiled brightly.

“If you’ve calmed down, we’ll continue. It’s okay, right?”

“Uh, un…”

Is it because my attitude is gentle? I felt Raewon acting shyly.

She must have been forcefully taken by Yeonseo quite a bit.

Anyway, I gently stroked her lips and gave her a silent warning.

Seeing that she was opening her mouth slightly, unlike before, it seemed okay.

“Hoop…”

As our lips met softly, Raewon let out a faint moan.

When I touched her teeth with my tongue, her mouth slowly opened.

I caressed the inside of her mouth slowly and very stickily, holding her hand tightly.

“Hooong.. Hoot.. Hoop…”

As our tongues intertwined smoothly, her moans grew louder.

I slightly tightened my grip on her hands and led her.

This must be the first time someone has put so much effort into a kiss.

After mingling our tongues for a long time, her expression completely melted.

“Poooh.. Haa.. Ha…”

“You look like you’re enjoying it. How is it?”

“This kind of thing… is the first…”

Her chest rose and fell rapidly, and she couldn’t finish her sentences.

Her face was slightly sweaty, and her face was even redder than before, perhaps from the kiss.

To get like this from just one kiss.

Her sensitivity is truly beyond imagination.

“You, why… are you so… good at kissing…”

“I do it with Gaeun whenever I have time. We even do it in hidden places at school.”

“So that’s why you’re not around during breaks…?”

“Yeah. We even have sex sometimes?”

“Perverts…”

I chuckled at Raewon’s harsh scolding.

I kissed her neck, then slowly reached for her vulva with my finger.

“Hoot..!”

A cute voice came out.

Since it was already very wet, there was no need for foreplay.

As soon as I inserted my finger inside, I felt her small vagina tightly clench.

Her reaction was very cute. When I poked her erect nipples, her vagina twitched.

“You’re so sensitive. Do you masturbate a lot?”

“No… I don’t…”

Is she embarrassed that her private parts are exposed?

She covered her face with both hands and answered with a moaning voice.

It was so obvious, but she was pretending not to, which was cute, so I wiggled my finger inside her vagina.

“Hooik, hiiik…”

The squelching sound echoed as her belly trembled.

Her slightly protruding eyes looked at me in protest, but.

I ignored her and gently scraped the inside of her slippery vagina with my finger.

The folds tangled around my finger, and the G-spot was lightly touched.

As I pressed on the spot that reacted the best, her vaginal fluid flowed like a flood.

“Ahh, haak.. Hiik…”

Since I’m always the one being dominated by Gaeun, seeing this reaction is fun.

After scraping the inside of her vagina for a long time, thin vaginal fluid spurted out.

By now, I should be able to have sex as I please.

I gently held her legs apart and inserted my finger into my own vulva.

Since my hand was already covered in vaginal fluid, it wasn’t difficult to moisten the inside.

I inserted two fingers and roughly rubbed the entrance.

“Hoot.. Krrik.. Hooik…”

I must have been too rough, as beastly sounds escaped my mouth without me realizing it.

Raewon also seemed to get excited by that.

She breathed heavily and rubbed her thighs.

After preparing by thrusting into my vulva for a while.

“Haa, haa…”

I caught my breath and pressed our wet vulvas against each other.

As I gently moved my hips in that position.

Squelch, squelch-

Our sticky wet vulvas rubbed together, emitting a lewd sound.

“Hoo, hoo…”

“W-wait a minute…!”

Raewon, with a look of utter shock, waved her hand.

But I couldn’t hold back anymore.

Keeping our vulvas pressed together, I roughly rubbed the surface.

Then, as our clitorises rubbed against each other, a tingling pleasure spread throughout my body.

Raewon covered her face with her hands and panted.

“How is it…? Is it… okay…?”

It felt like our vulvas were deep kissing, rubbing against each other.

After exchanging vaginal fluid for a long time, I pulled my vulva away.

Then, we kissed passionately and rubbed our vulvas together again.

The mat was already soaked, and Raewon’s face was as red as a beet.

She couldn’t say anything, just moaning like an idiot and trembling.

Squirt-

As I squeezed and twisted her erect nipples, vaginal fluid immediately spurted out.

“There..! Don’t twist-“

Pfft, pfft-

The more she told me to stop, the more intensely and persistently I targeted her nipples.

I licked around her areola with my tongue, then bit down hard.

Then, I roughly stimulated the other nipple with my index finger and thumb.

As a result, Raewon, as if a dam had burst, was gushing vaginal fluid.

“G-get out. Stoooop! KYAaaaaaaak!!”

She screamed and received the intense orgasm with her whole body.

Then, with a final kiss and vigorous thrusting into her vulva.

Shhhhhh-

Having reached her limit, clear urine poured onto the mat instead of vaginal fluid.

“Ah, haak.. Hat, ah. Higg, hoot…”

She felt intense shame and kept releasing embarrassing things.

After the intense sex finally ended.

Raewon breathed heavily, her lower body trembling.

“Hiiik, hik.. Stop.. I told you to…”

She seemed very embarrassed about peeing in front of her friend.

Tears welled up in her narrowed eyes.

Her hiccuping sobs were stimulating my sadistic desires, but.

It was indeed severe, so I decided to comfort her.

“I’m sorry. I got carried away… Let’s stop crying, okay? I’ll buy you delicious egg tarts later.”

“…Really?”

“Really. So don’t cry.”

When I offered a bribe while stroking her hair, Raewon stopped crying and giggled.

This simplicity and tenderness. I felt my heart skip a beat, so I hugged her tightly.

Poo-guk, poo-guk-

“Uh-heok, eh-heuk…”

On the other hand, more intense sounds were heard from above.

As I lifted my head while holding Raewon, the first thing I saw was Yeonseo, on the verge of fainting.

“You’re tall, so your mouth can’t reach my vulva? Suck properly.”

“Sorry, haaae…”

Gaeun was thrusting her dildo into Yeonseo’s vulva, which was completely wet.

Although it was a 69 position, it felt more like a one-sided interaction than a mutual one.

Yeonseo moaned under the merciless oral sex, but she struggled to suck Gaeun’s vulva.

Gaeun didn’t show any significant change in expression, as if it wasn’t good enough.

Squelch!

After thrusting the dildo in and out repeatedly, she inserted it as deep as possible and then rotated it.

Yeonseo spurted again.

“Heek, hee-hek…”

‘Wow…’

It was a very stimulating porn that only elicited a ‘wow’ from me.

Compared to this, what I had with Gaeun was truly sweet without end.

“Hmm… You like it here, right? Pressing down on the deepest part… then scraping around there.”

“I like it… I like ittt!!”

Her hand skills are truly amazing.

Even though she was using a dildo, she was as skilled as if she were using her own body.

As I watched their sex, I felt something flowing down my thighs.

It was sticky vaginal fluid.

Looking at Raewon’s expression, she seemed to be feeling the same way.

“…Shall we do it again?”

“Un…”

Raewon nodded.

After that, the four of us spent the day together, mixing our bodies.

As promised, the swapping ended today, but there’s one slight change.

KakaoTalk-

“You’re here again?”

“Yeah.”

“What kind of picture is it today?”

“Pictures of outdoor exposure play.”

“Ooh… Shall we try it sometime, Sewon-ah?”

“…I’ll think about it.”

That change was that the two of them sent sex pictures or videos almost every day via KakaoTalk.

It was the beginning of a surprisingly not-bad, debauched life.

Having sex as a group of four would be a story for later.

We were having a very stimulating vacation.
