“…Haa, *gasp*. *Ugh*!?”

*Slap!* While we were still in the midst of it, an inexplicable impulse made me involuntarily raise my hand and firmly smack Baek Ayun’s buttock.

Her gray hair swayed wildly, tickling my body in turn, and Baek Ayun stuck out her tongue, her face slightly flushed.

“Haa, heuu, hooo…”

The sight of her catching her breath was utterly sensual. The way her small body accepted me, and yet showed no signs of pain, was equally so.

Even though I was using vitality absorption, Baek Ayun seemed completely unfazed.

‘Even if it’s fundamentally affected by total stamina…’

Could this even be possible? I let out a hollow laugh in disbelief, but that wasn’t to say it was bad.

Unlike Cheon Soyul, who desperately tried to overpower me, Baek Ayun wasn’t the type to be so obsessed with winning.

If anything, I’d have to be careful when her switch was flipped, but…

In other situations, I just needed to satisfy her sufficiently.

*Squish, squish*…

“…*Gasp*, *yelp*.”

This was exactly that feeling. I moved my hips slightly slower, then intentionally thrust my body forward the moment Baek Ayun’s body trembled.

*Thwack!*

“A choked gasp!?”

This time, she let out a genuine scream, her ten fingers tightly curling around the seatback.

It seemed difficult for her to stand bent at the waist, as her legs trembled quite a bit.

“…Ah, ah.”

I slipped my arm under Baek Ayun’s stomach, holding her in place.

I held her body tightly so she couldn’t fall as she pleased.

Baek Ayun’s ear tips turned bright red as if she found the contact rather embarrassing, but she didn’t refuse my touch itself.

“A sharp gasp!?”

So I decided to go one step further. I moved my hand a little playfully, lightly fondling Baek Ayun’s belly fat.

As expected, I received an excellent reaction. Unable to simply let this pass, Baek Ayun quickly twisted her neck and looked at me with trembling eyes.

“O-Orabeoni? Th-this, this is a bit too embarrassing, *e-eh*…? *Squeal*!?”

“Shh.”

Of course, I wasn’t going to accept such resistance. I deliberately changed my touch to be more suggestive, rubbing Baek Ayun’s belly.

I rubbed her belly button with my index finger, then covered the area with my palm, and finally pressed down on her most sensitive lower belly with my index and middle fingers.

“A low moan.”

The last reaction, in particular, was truly artful. Baek Ayun let out a wanton moan, her eyelids twitching, and between her legs, lubricating fluid streamed out, squeezing past our connection.

‘Hmm.’

How good must she feel to be gushing like this again?

Given this reaction, shouldn’t I, as her Oppa, make my younger sister even happier?

That thought suddenly occurred to me, and I was aware it was quite a crazy idea, but I didn’t feel the need to correct the thought itself.

I merely twisted my lips into a smirk and softly stroked Baek Ayun’s buttocks.

“Her moans grew more intense.”

Baek Ayun let out a rather peculiar sound and covered her face with both hands.

Now that I held her, she didn’t even bother to grasp the seat anymore.

I looked down at her reddened buttocks… and felt my own sexual arousal, already near its peak, intensify to its limit.

It was an instinctual desire. I wanted to possess her more. I wanted to plant my seed deep inside her.

Perhaps it could be called a rather vulgar emotion, but I decided not to think of it that way.

Just for today, Baek Ayun had pounced on me first. I was merely responding.

“…You’re the one at fault, Baek Ayun.”

“Eh, *gasp*? What…?”

Baek Ayun stammered her reply, a bewildered expression on her face at my softly murmured words.

I didn’t bother to add anything more.

After all, she was my little sister who loved me dearly, so I had an inherent certainty that she would like whatever I did.

Wasn’t she the one who, even during our first encounter, had forcibly wrapped her legs around my waist, demanding that I spill inside her?

If so, there wouldn’t be any particular problem if I did the same today.

‘Now that I think about it, not bringing condoms feels like a clever idea in its own way.’

I let out a soft snort of laughter, a rather absurd thought coming to mind.

For your information, Cheon Soyul was still engrossed in her own pleasure.

That’s right. Perhaps not deviating even a millimeter from what I expected, she was poking herself downstairs while watching Baek Ayun and me intertwine our bodies.

Could it really be that good? To be honest, I didn’t quite understand such a fetish…

Frankly, just imagining Cheon Soyul or Baek Ayun doing such things with a man other than me would make me boil with rage.

I’d probably freeze the other man’s groin, then burn it off, or something.

‘Well, it’s not like that’s going to happen anyway.’

Anyway, there wasn’t much value in entertaining meaningless hypotheticals.

I decided to focus on the present moment.

“I let out a short breath.”

After a short exhale, I began to increase my pace. I roughly gripped Baek Ayun’s twin tails and started moving my body in a rather violent manner.

*Thwack─!*

“A sharp gasp!?”

Baek Ayun’s bare body, revealed in its pristine white, particularly her lower back, convulsed violently.

Intermittent drops of lubricating fluid wet my shoes, and her face was completely flushed.

Was it because I had thrust into her quite roughly this time? Baek Ayun’s expression showed a mix of pain and pleasure, but—

“She let out intense moans…”

She certainly didn’t seem to dislike it. The suggestive sounds flowing from her, as if she felt good, were proof enough.

I continued my back-and-forth motion, half-lifting Baek Ayun’s small body, and Baek Ayun gradually approached her climax.

“Her moans grew more intense.”

Judging by the lubricating fluid she was releasing, she seemed to have already climaxed several times, unlike me.

I couldn’t tell exactly how many times it had been. I could only surmise that this would likely be her final orgasm.

“A groan.”

In any case, I too had reached my limit.

It would be difficult to hold out any longer.

I wanted to enjoy Baek Ayun’s soft, firm body for a little while longer, for hours if I could, but…

It wasn’t something I could control. I gave up and decided not to hold back my release.

“…Turn your head, Baek Ayun.”

“A choked gasp, ‘Yes, eh…?’”

Finally, I called Baek Ayun in a low voice. She dazedly questioned me with a pleasure-soaked expression, yet she obeyed my words.

“…*Mmph*!?”

I grabbed her head, which she had turned towards me, a bit roughly and kissed her.

I inserted my tongue, ravaging her lips and the inside of her mouth without restraint.

Baek Ayun, who had initially looked surprised, soon melted and reciprocated the kiss.

Her eyes were filled with deep affection and love for me.

While holding her chin, I subtly shifted my gaze to quickly observe the expression on Cheon Soyul’s face on the opposite side.

‘…Well now.’

And I couldn’t help but let out a silent chuckle internally. It was clear she was drenched in a mix of depravity and sexual pleasure, but…

Yet, seeing me fully enjoying myself with Baek Ayun without even paying attention to her, her expression seemed quite complicated, almost distressed.

The key point was that she still didn’t stop her wanton fiddling with her own private parts.

I let out a hollow laugh as I continued to explore Baek Ayun’s lips and the inside of her mouth.

Perhaps I, who received such unwavering love from such wonderful women, was quite blessed compared to the things I did…

With such trivial thoughts—soon, the urge to ejaculate reached its peak.

*Gush, gush*…!

“A muffled groan…!”

Soon, I felt something hot gush out from my shaft.

Baek Ayun’s eyes, who likely felt it most acutely, widened considerably.

But she didn’t evade it. Instead, she struggled, twisting her body as if to better receive my semen.

She instinctively wore an obscene smile, parting her lips.

Her eyelids and facial muscles twitched, and her lower belly rippled repeatedly, indicating that she was likely experiencing a considerable amount of satisfaction.

“…A delighted gasp!”

I aided the amplification of her pleasure by lightly tracing her lower back with my fingertips.

Sure enough, Baek Ayun wore an incomparably blissful expression.

Soon, the rather long-lasting release concluded, and Baek Ayun, looking utterly exhausted, collapsed onto the seat, limp with lethargy.

“She let out a long sigh…”

And I directly hit her with a remark.

“Don’t fake being exhausted. It’s too obvious.”

“…Ah, I was caught.”

At that, Baek Ayun quickly recovered, as if she had never shown any signs of exhaustion, and sat her upper body upright again.

Other than her slightly ragged breathing, she didn’t seem to have expended much physical energy, which was the most terrifying part about her…

“…Ah.”

Still, I had no intention of doing anything more. Not only because of physical limitations, but also because there was a limit to flight time.

The estimated arrival time displayed on the in-flight monitor had already decreased to about an hour.

If I were to do anything more and the pilot inside came out…

‘…I don’t want to imagine that.’

Firstly, it would be a huge inconvenience, and if such a story reached Yang Chan-ho-ssi’s ears, there’s no telling what he’d say.

Thinking I should at least wipe down the dirtied floor later, I slowly detached myself from Baek Ayun.

*Squish*…

“…A low moan.”

Baek Ayun let out a short moan, seemingly feeling considerable heat even from that brief friction.

I felt my lower body twitch again, but I didn’t show it.

I simply looked down at my own ‘thing,’ covered in lubricating fluid and semen… and then voiced a sudden amusing idea.

“Cheon Soyul.”

The softly murmured name was, without a doubt, my fiancée’s.

Cheon Soyul on the opposite side replied in confusion.

“…Huh?”

“Come here.”

“Huh, huh?”

I gestured for my fiancée, who had probably also reached her climax at the same time Baek Ayun and I did.

Cheon Soyul’s eyes darted around for a moment, but she didn’t disobey my words.

Her legs trembling, her panties dangling around her knees, she walked over.

I spoke directly to her, without beating around the bush.

“Didn’t it feel a little lacking doing it alone?”

“…A squeak, ‘Ugh?’”

“Of course, it must have felt good, but I’m willing to give my wife-nim this last chance.”

Cheon Soyul’s eyes trembled. She didn’t seem to guess what I was about to say, but instinctively swallowed hard.

I looked at Cheon Soyul, subtly curving the corners of my lips upward.

Then, I gestured downwards.

Cheon Soyul’s gaze followed.

“Suck it.”

I commanded succinctly. An order to clean the soiled ‘thing’.

“…What?”

Cheon Soyul wore a momentarily blank expression, showing she didn’t understand my words, but I calmly continued to explain.

“If you don’t do it, I’ll have Ayun do this too. Is that okay? To have even that taken away?”

“…!”

“Hmm, you don’t seem too keen on it… Then, Ayun, could you clean this side for me?”

Baek Ayun’s eyes sparkled wide. She nodded her head as if she would lower herself immediately if only I said the word, and at that reaction, Cheon Soyul showed signs of great panic.

“N-no, wait…!”

Cheon Soyul urgently reached out, restraining Baek Ayun who was about to approach me.

She whirled around to face me, an expression that was neither crying nor laughing on her face.

“You, you just *have* to make me and her compete like this…?! Th-that’s a bit much, isn’t it…?”

I didn’t answer, merely shrugging my shoulders. It was a gesture implying that she should decide for herself, and Cheon Soyul seemed to understand.

“*Ugh*, *uh*…”

Had she realized there was no other option?

Cheon Soyul made a tearful face and knelt down.

“…You’re mean…”

From below, my wife-nim’s voice, grumbling at me with a resentful gaze, sounded irresistibly charming.

I chuckled silently, and Cheon Soyul soon opened her mouth without a word and stuck out her tongue.

*Slurp*…
