Chapter 1130: Side Story – Underwater Cave (3)

-Tcheupeup….

“Hoo, hoo, hooneuueu….”

After cumming, Han Seon-ah carefully withdraws the mouth that was sucking my cock, her expression slightly relaxed.

A single stream of liquid, a mix of my semen and her saliva, carefully dripped down from the corner of her mouth.

“Good work, Seon-ah.”

“…Thank you, Oraboni.”

“Your blowjobs are getting better and better. Today felt great too.”

“I, I was able to come too thanks to your fingers, Oraboni. Thank you for always paying attention to me.”

As she said that, Seon-ah was leaking sexy fluids both above and below.

The fact that she didn’t bother fixing her swimsuit, choosing instead to expose her slightly disheveled body, really only meant one thing.

“Want to do more?”

“…Could I stay for about 30 more minutes, Oraboni?”

“Sure, if we stay too long, someone will be waiting, so let’s just stay 30 more minutes.”

“……Yes.”

What else could I do? She likes lewd things more than her sisters or sightseeing.

Seon-ah, who had a particularly strong libido compared to other women, so it was my job as her lover to satisfy it.

…And perhaps after tonight, I’ll become her husband too.

“So, where do you want it today? Front? Or back?”

“…Do, do I have to choose just one?”

“If you behave, Seon-ah, we might just have time for two rounds.”

“I’m always well-behaved, Oraboni.”

“Yeah, I know.”

It was obvious Seon-ah would say that, so I wasn’t particularly surprised.

…Still, two rounds in 30 minutes would be a bit tough, so the chance to leisurely sightsee the cave was practically gone.

Sex outdoors is inherently limited in terms of positions, unlike in places like beds or sofas. Especially in places like this, without any structures to support the body, just flat ground.

The place where Seon-ah and I were sitting was a circular rock in the middle of the cave, surrounded by seawater, making it impossible to even lean against a wall with our hands. Therefore, the positions possible in such a situation were quite limited.

“Lift one leg, hug my neck, and lean towards me, Oraboni.”

“…Yes, Oraboni.”

Seon-ah, with one leg held by me, obediently wrapped her arms around my neck. Her large breasts pressed against my chest as she hugged me tightly.

-Jjilkkeok.

“Eueut, heueung…”

Down below, I pushed my cock into her slightly spread opening. After hugging her body tightly once more in that state.

-Beonjjeok!

“Heueueueup…!!”

I lifted Seon-ah, my cock still inside her, into the air. Holding her back and buttocks tightly with both arms.

“Haa, heu, heueueut….”

“Hold on tight, Seon-ah.”

“Yeees, O, Oraboni….”

Han Seon-ah obediently followed my words, gripping my waist tightly with her legs. If we were going to do it in a place like this, there were practically no positions possible other than a standing fuck. Because there was nowhere to lean or lie down.

Using Belle’s dungeon would have been fine, but since this was a secret space Seon-ah went out of her way to bring me to, suddenly moving elsewhere seemed pointless.

Holding my sister’s body, embraced by me, tightly, I moved Seon-ah’s body up and down, continuing the sex inside the underwater cave.

-Jjilkkeok!

“Hoo, hooeup…!!”

-Jjilkkeok, jjilkkeok!!

“Hugeueup…!! Haa, heueung…!!”

Han Seon-ah, holding me tightly, writhed her hips with lewd moans. My cock repeatedly thrust deep into her vagina, which was as wet as the passage we used to get here, inside the cave.

-Jjilkkeok, jjilkkeok!!

“Haa, heueup…!! O, Orabonihiit…!!”

-Jjilkkeok, jjilkkeok, jjilkkeok!!

“Harder, Seeeggeet…!! Enough to break Seon-ah’s pussy, do it haaard…!! Haa, haaaang…!!”

My sister, hanging onto me with her legs, diligently thrusting her hips with an utterly lewd request. Were ladies with long black hair all just very horny, or was she really moving so diligently? It would have been fine just enduring it, but she actively urged her own climax with even more intense movements.

…If she asks me to go this hard, of course, I have no choice but to oblige. I just have to fuck her hard enough to break, just as she wants.

-Jjigeueueuk….

“Hee, heu, heu, heeek…?”

To thrust deeply in one go, I pulled my hips back as far as possible, almost letting my cock slide out.

-Jjikkeoeok!!

“Eueup, heugu, kkeut…………?!”

I thrust the roughly 20 centimeters that had exited Seon-ah’s body back in all at once. Seon-ah climaxed from the strong impact, felt even at her cervix, unable to even fully let out a moan in surprise. Before she could even grasp what was happening, I thrust my cock, pulled back maximally again, straight into Seon-ah’s vagina.

-Jjikkeoeok!!

“Kkeuhe…!! Heu, geuhiit…!!”

Even for Seon-ah, who was the least sensitive among the three sisters, the pleasure was so intense that a single thrust sent her to climax. Along with that, a stinging sensation began on the back of my neck. It seemed she was unconsciously scratching my back with her nails, likely due to the impact being much stronger than expected. It stung a little, but I showed no sign of pain, simply continuing to thrust into my sister’s body. Any injuries could be treated later, but this fleeting heat would cool down if not seized now.

“Kkeuhe…!! Ora…! Heu, hee…!!”

-Jjikkeoeok!! Jjikkeoeok!!!

“A, As expected…! A, A little…! Heu, heukkeueueuk…?!”

All she could do was desperately hang on, climaxing repeatedly as she was pierced by my cock. As we shared rougher sex than usual, Seon-ah and I, the urge to cum began to build within me as well.

“Seon-ah, I’m gonna cum inside!”

“……Gyehek. E, Eh….”

…It didn’t seem like she could properly hear or respond, but Seon-ah wouldn’t refuse internal cumming, so it probably doesn’t matter much.

Thrusting vigorously into Seon-ah’s body, moments from losing consciousness, I vomited all the pleasure accumulated over ten minutes inside her.

-Jjikkeoeok!!

“Heu, heukkeu…!!”

Into her body, unable to even utter a proper voice at the end, I forcefully released my desire.

“Hee, heu, heueut…!! Hi, higeek, heek…!!”

Even after the first cum, just the sensation of my cock twitching and spraying semen made Han Seon-ah flinch and writhe her hips. It was truly impressive how she still moved her hips even in her semi-conscious state. Seeing this made me think it was just like Seon-ah.

Thus, after expelling the very last drop remaining in my cock into her body.

“Eu, heueu…. Heugu, heeee….”

What remained in the underwater cave was, in the end, just my sister, collapsed in submission to pleasure.

Although my sister initially asked for both front and back, sadly, that wish couldn’t be fulfilled. This was because Seon-ah herself, who made the request, passed out during sex.

Because she demanded I fuck her hard enough to break her pussy, I got a little too excited myself. In the end, it was practically like raping her body with genuine force.

I thought she would endure it sufficiently, given she had the highest tolerance for lewdness among the three sisters, but in the end, she collapsed unconscious right after the final internal cumming.

‘Indeed, body size and tolerance for pleasure aren’t directly proportional.’

If it were CEO Seo Ok-hee or Min Hyunyoung, who are much smaller than her, they wouldn’t have collapsed from just this much.

Perhaps her heat cycle coinciding was a factor, but still, collapsing after just one round of sex was quite unexpected. Although the intensity of the sex itself was several times stronger than a typical encounter.

After that, I simply carried her out of the underwater cave. Of course, since she couldn’t use the underwater passage while unconscious, I had to use a slightly different method.

Open the warp gate leading to Belle’s dungeon.

Place Han Seon-ah inside Belle’s dungeon.

Retrieve the warp gate, then swim out alone.

Open the warp gate again and take Han Seon-ah out.

That was roughly the process of getting Seon-ah out. Thanks to being alone in the dungeon for a few minutes (about 3-4 hours) during that process, Seon-ah recovered somewhat.

“I’m sorry, Oraboni. I asked you to do it, but I was the one who passed out first….”

“It’s okay. I should have held back a bit, but I got carried away.”

“N, no! You weren’t excessive, Oraboni! It, it was because I’m inexperienced and couldn’t properly accept your affection!”

“I don’t really think that’s the case…”

“…Next time, I’ll endure more firmly so I don’t disappoint you, Oraboni. So, um… C-can you do it like just now next time too?”

…She just needed an excuse to do it again.

Then again, Seon-ah passing out means she felt good enough to pass out. Wouldn’t she rather regret not being able to feel the full sensation because she lost consciousness?

“Sure, Seon-ah. If you want it, I’ll do it anytime.”

If you want, even tonight is fine.
