Chapter 1129: Side Story – Underwater Cave (2)

It wasn’t like I hadn’t expected things to turn out this way. Given Sun-ah’s personality, it was obvious she’d react like this the moment we were alone.

I just didn’t expect her to start so soon, though. I thought she might take a moment to appreciate the natural beauty before cautiously setting the mood.

Suddenly ripping off my swimsuit and shoving her face at me was a bit startling, even for me.

“Hoo, T-Taekyung Oraboni….”

“……”

Unlike me, who was immersed in the beauty of the jewel cave, Sun-ah seemed to have a different kind of cave getting wet.

Since they’re twins, their heat cycles come around the same time anyway. Even the usually docile Jin-ah would pounce on me while I slept, so imagine how it is for Sun-ah, who has a stronger libido.

It’s an Oraboni’s duty to help his younger sister relieve her sexual urges, so I don’t really plan on refusing.

“Do you want it, Sun-ah?”

“Ah, s-sorry, Oraboni. Come to think of it, I didn’t even ask if you wanted to….”

“It’s okay. I knew anyway.”

That mood of leisurely lying on the cave rocks, appreciating the scenery for a bit before cautiously making love… let’s save that for another time. Right now, helping this poor younger sister relieve her urges comes first.

Besides, Min-ah and Jin-ah each had their private time last night, so it feels a bit unfair to skip Sun-ah.

“If you want to, you can, Sun-ah. It’s a vacation you came here for, so you should do whatever you want.”

“…Then, may I pleasure you with my breasts, Oraboni?”

“With your breasts?”

“I recently learned a new way to pleasure a penis with breasts, and I wanted to show you, Oraboni.”

…Is she talking about Feyzili? But I’ve probably done Feyzili with Sun-ah a few times already.

I had experience trying various positions with my younger sister, who is full of curiosity about sexual acts. Feyzili was naturally one of them.

Wondering if there was something different from what I knew, I waited patiently, and soon Han Sun-ah’s breasts began to envelop and rub against my penis.

-Malkang, malkang.

“Eut, euut…”

-Malkang, malkang.

“Hoo, hoo, hoo…”

Large breasts rubbing against my erect penis, moving back and forth from above.

It was definitely Feyzili, but slightly different from how we usually do it.

While our usual Feyzili involved inserting the penis vertically between the breasts and rubbing up and down, what Sun-ah was doing now was inserting the glans between her breasts and rubbing it back and forth.

Each time her body moved back and forth, the tip of my glans poked into the inner cleavage of Sun-ah’s breasts. If I had to name this act… maybe Vertical Feyzili?

-Malkang, malkang.

“H-how is it, Oraboni?”

“It feels good, Sun-ah.”

“Heehee, that’s a relief. My Unnies probably can’t give you this kind of position, Oraboni.”

As she said, Sun-ah is probably the only one of the three who can do this position. Han Min-ah’s breast size goes without saying, and even if Jin-ah brought her breasts together, it would only be enough to swallow my glans. The act of gathering large breasts to create a pseudo-vagina for rubbing was possible only because it was Sun-ah.

I wonder if she was looking for swimsuits with holes in the cleavage when choosing bedroom wear because she wanted to try this position from the start.

“But, as expected of you, Oraboni… I’m not exactly small-chested myself, but I didn’t realize I could only cover about half of it…”

“It feels good enough even with just that, so it’s fine.”

“Since you say so, Oraboni… I should make it feel even better.”

-Jureureuk.

With those words, Sun-ah continued the Feyzili, spitting a little saliva into her cleavage.

As her saliva dripped several times into the slightly tight cleavage, I could feel a slippery liquid touching the tip of my glans.

-Chilpeok, chilpeok…

“Puh-hoo… H-how is it, Oraboni…? Ah, it feels better than before, right…?”

“Yes, it feels good, Sun-ah.”

“Hoo, huh, huh-heut… I’ve been researching how to please you, Oraboni… Hoo-hoo…”

Honestly. Where does she keep getting this knowledge that’s so heavily biased towards lewd things?

Of course, I like Sun-ah’s passionate attitude, so it’s actually good. The fact that she researches on her own how to make me feel good is arousing in many ways.

For several minutes, she moved her body back and forth, her large breasts covering about half of my penis. My penis, sensing the signal, twitched as if about to ejaculate any moment.

-Chilpeok, chilpeok, chilpeok!

“Hoo, Sun-ah! It’s coming!”

“Yes, Oraboni… Please, cum all inside my breasts…!”

With those words, Han Sun-ah squeezed her breasts together and diligently rubbed my penis deeper inside. Not long after, the hot liquid spurted from my penis into her breasts, and sticky semen soaked the inside of Sun-ah’s large breasts.

-Jureuk…

“A-as expected of you, Oraboni… So much…”

Even after ejaculation, Han Sun-ah held my penis close for quite a while before gently parting her breasts to check inside. As soon as her breasts opened, a mixture of Sun-ah’s saliva and my semen flowed stickily down below her body.

“……”

-Haljak.

“…Since you went into the sea today, Oraboni, your taste is a little salty.”

She even dipped a finger into her cleavage and tasted my semen.

It made no sense to hesitate in front of Sun-ah, who was openly seducing me like this, so this time, I boldly lunged at her.

“How dare you tease Oraboni? Are you prepared to be taken?”

“Yes.”

“You even brought me to a place where no one can see. Did you want it that badly?”

“Yes.”

Truly, she’s consistently honest. She was completely different from her Unnies, who would try to escape embarrassment with lies or excuses.

Seeing her face flushed, she seems to feel embarrassment similarly, but why is her personality the complete opposite of the two of them? Thinking such a trivial thought as ‘maybe foxes are obedient because they belong to the dog family,’ I pushed her shoulder, making her sit on the stone floor.

“First, clean my dick. It’ll be a bit messy if I enter like this.”

“I don’t mind if Oraboni’s dick has saliva or semen on it?”

“Should I take that to mean you don’t want to suck Oraboni’s dirty dick with your mouth, our Sun-ah?”

“Haaap.”

Han Sun-ah, as if realizing she hadn’t meant that, quickly took my penis into her mouth and shook her head back and forth. She moved her head diligently, her mouth holding the penis that hadn’t even gone in halfway into her large breasts, cleaning off her saliva and semen from it.

-Tseupeup, tseupeup, tseupeup…

“Eup, eu-hreuup, hreuup…”

Naturally, she couldn’t swallow it all with just her mouth, so she used her entire throat to swallow. I just received fellatio from Jin-ah this morning, but Jin-ah definitely can’t compare to Sun-ah when it comes to lewd abilities. Jin-ah still finds the sensation of swallowing my dick down her throat awkward and struggles with it. On the contrary, Sun-ah is already so proficient that it feels almost no different from fucking her in the pussy.

-Tseupeup, tseupeup…

“Hoo-eup, hoo, hoo-euup…”

If the goal was just to clean my dick, it would have been over already, but Han Sun-ah still hadn’t taken it out of her throat. As a token of gratitude for her diligent efforts in pleasuring my dick, I also removed Sun-ah’s swimsuit bottoms and slowly caressed her two holes.

-Jjilggeok!

“Hoo, hoo-geuup…”

-Sseupuuk.

“Hoo-eu, hoo…. Hoo-neuup…”

Two fingers, the index and middle, went into the vagina. The thumb, slightly short but thick, went into the anus. The method of stimulating and caressing both holes simultaneously with one hand. This caress, which some might find shameful, was one of Han Sun-ah’s favorites.

Since she accepts information about sex as openly as possible without prejudice, she has the least resistance among the three sisters to a penis entering her butt, and she feels the most pleasure from it too. Since it was obvious we’d end up doing both front and back anyway, simultaneously caressing both holes was practically routine during sex with Sun-ah.

-Jjilggeok, jjilggeok, jjilggeok!

“Hoo-geu-euup! Hoo-eup, hoo-geu-euup!”

-Sseupuk, sseupuk, sseupuk!

“Ugh, huh, huh-euung! Hoo-eu-euup….”

Her vagina was wetter than the underwater cave, and her anus, though not wet, tightly gripped the thumb. Sun-ah’s body was filled with the desire to have sex from the moment she invited me to this cave.

As her body became increasingly ready for intercourse, the urge for a second ejaculation began to build in my penis.

“Sun-ah, I’m cumming again! Swallow it all!”

“Hoo-eu, hoo-euup…!”

Sun-ah’s body trembled violently as she took the second ejaculation with all her might into her throat, reaching her own climax.
