RE: Keep it in the Family (Secret Class) 185 — Under the Stars VII

With Mia, I had always managed to pull out in time. Every single time. Despite the fact that we had been having unprotected sex ever since that first night in the Training Center.

But with Su Ah... I had simply... lost control.

During what was truly the first, intensely mind-shattering sexual encounter of my life, I completely forgot the most crucial rule I had established for myself. This reckless gamble I was playing with my own sisters was not one I intended to lose. Now that I had, the overwhelming guilt, coupled with the lingering tremors of an explosive climax, struck me with the force of a lightning bolt.

"Is it a safe day?" I repeated, my voice sharper than I meant it to be. I inwardly chastised myself. What kind of fool asks that after the fact?

Shouldn't we have discussed the ramifications of intercourse in a mountain setting before this could have possibly occurred?

Still, witnessing her blood mingle with my own essence caused my jaw to clench in pain. I had come so far with her, and I should have exercised greater caution. I remained seated, my gaze shifting repeatedly between her beautiful, panting, flushed face, utterly spent, and the mess between her thighs.

"Umh..." Su Ah's voice was soft and trembling. She pushed herself up onto her elbows, looking down at the result between her legs. Her expression was difficult to decipher, a peculiar blend of awe and dismay. "It... should be." She stammered, her mind evidently cycling through her personal calendar. "I... I believe it is. But I'm not entirely certain..."

I sat up abruptly. That hint of uncertainty made the situation feel even more precarious. It solidified the realization that I had committed the unthinkable; that, indirectly, I had jeopardized two lives through sheer chance. However, not all hope was extinguished, and we both understood that. "You can take the morning-after pill..."

"Yes." She murmured, her lovely pale features contorted into a tight, shame-filled expression. It was as if the entire responsibility rested solely on her shoulders, rather than both of us having acted impulsively.

"I couldn't restrain myself, I apologize." I attempted to offer an apology, though I wasn't entirely certain what precisely I should be sorry for. She had desired it just as intensely as I had. She hadn't urged me to pull out, and it likely hadn't even crossed her mind.

But it was true that she had not requested it, unlike Mia typically did.

Su Ah simply glanced down at her hand, which hovered above the smeared, blood-stained, slick crevice between her legs, and shook her head. "Don't... it's not your fault. Actually... this, the chance to experience what it feels like..." Her eyes took on a wistful quality. Then, she raised her gaze back to me, her cheeks so flushed that her entire face seemed aflame. "To feel you inside me like that… it was… it was the most sublime sensation I've ever experienced in my entire life. I… I wouldn't mind doing it again, if it's with you."

She looked away, resting back on her hands.

"......."

The sight of her nakedness, her flushed and disheveled state, was as captivating as gazing upon Mia's unveiled, post-deflowered body for the first time.

I still found it difficult to comprehend the path I was now treading in this new existence. Out of all the women I could have been intimate with, the very first one to have taken me raw and deep was my own sister. Yet, one thing I knew for certain: my body, heart, and mind would never permit me to relinquish either of them.

My primary concern was for the future, and whether this unconventional relationship could withstand the immense pressures we would inevitably face in the coming months. I also worried about the possibility that, one day, they might desire marriage, children, and how I would cope with such a situation.

What kind of perverse family would I be establishing if I kept both of them exclusively to myself?

The scandal that such an arrangement would ignite was unimaginable.

I doubted Su Ah and Mia had contemplated these future complexities, and I wouldn't broach the subject. For the present, we would have to navigate these circumstances as they unfolded.

Still, a small pang of worry arose, contemplating the possibility that their feelings might change later on, that being with me might eventually become insufficient. That, ultimately, I myself might not be enough for them.

"I wouldn't mind either." I found myself stating, without much surprise at my own words. When all was considered, it was a simple, undeniable truth. "In fact, I cannot think of a single other woman I would rather be sharing this with."

"Jae-il..."

Her eyes widened momentarily before a beautiful, languid smile graced her lips. And it would have been even more stunning, if only her eyes hadn't held such a... look.

I frowned, blinked, and then the expression vanished as if it had been a mere figment of my imagination.

"So..." Su Ah cleared her throat and sat up properly. "We... should probably tidy up a bit. It's rather... sticky."

A snort escaped me at her deadpan delivery.

She glanced at the state of the sleeping bag. "Oh, this is... this is a disaster."

She wasn't wrong, in fact. The sleeping bag was marred by stains of various kinds – sweat, blood, and other bodily fluids. We peeled ourselves from its confines with winces and groans, the cold mountain air hitting our bare skin and causing us to shiver.

"Well, there goes our sleeping bag," I remarked, attempting to fold it in a way that concealed the evidence, a futile effort. It resembled a scene from a very, very joyful crime. "I don't think it's... usable anymore. It's far too wet and... soiled."

Su Ah wrinkled her nose. "Let's offer it as a sacrifice to the elements."

"Not much of a choice there, is there?" I chuckled. "It's not like we'll be carrying it home."

We used the remnants of the small towel I'd retrieved from my pack to clean ourselves as best we could. The coarse fabric felt cold against my skin, and the limited material meant we had to share.

After she finished, her movements somewhat awkward but resolute, it was my turn.

The rain outside was still heavy, though it seemed to be subsiding slightly.

"Come on," I said, unrolling my own dry sleeping bag beside the ruined one. "In here."

Su Ah lowered her head, a faint blush returning to her cheeks, and slid in beside me. We lay facing each other, the air crisp, but the warmth of our bodies gradually dispelling the chill. It would take time, but we weren't overly concerned.

"Okay, first things first. How are you feeling, truly?"

Su Ah tilted her head back, her gaze fixed on the cavern's ceiling, her eyes hooded. "Good," she let out a low, satisfied hum, slowly closing her legs. "Very good, actually." The lingering tension in her eyes finally melted into a soft, sweet expression of contentment.

"How about you?" she asked.

"Better... and emptier."

She snorted, a smirk playing on her lips.

"Are you... sore?"

She shrugged. "A little. I don't... regret any of it, if you're wondering. I'm just a bit nervous about how this will play out for us. I'm not naive; I know we can't exactly publicize this. And I'm also aware of the potential major repercussions for you... but I just couldn't help myself."

"We both wanted it," I stated. While Su Ah had orchestrated the situation, her intentions weren't malicious. At some point, this desire became mutual. I couldn't, and wouldn't, deny the impact this lust had on my judgment, nor the fact that I was still processing the aftermath of an intensely satisfying sexual experience.

"I feel better knowing that, Jae-il."

Su Ah nestled closer. We remained unclothed, and my erection was pressed against her soft, moist skin. Her hand, which had been resting on my chest, moved to cup my non-erect penis, her fingers giving it a curious squeeze. Naturally, blood surged into the soft flesh at her touch.

A playful sparkle appeared in Su Ah's eyes. "Well, well... someone's awake again. Should we..." She tilted her head. "... go for another round?"

I chuckled. "Tempting, Noona. Very tempting. But after losing control once... I don't trust myself for a second round tonight. At least not one that involves finishing inside you... which is something we should avoid if we don't want a surprise mini Jae-il or mini Su Ah appearing in the world."

A blush crept up to Su Ah's ears. She shot me an annoyed glare as I smirked, amused. "Humph. I see how it is..." she huffed, though genuine annoyance was absent from her expression or tone. "I'm surprised you say that. Do males generally lack self-control?"

"Self-restraint, yes. I've had more than enough over the past few months. And the occasional lapse in judgment here and there."

"Only Mia Unnie knows the extent of those lapses in judgment?"

"Sometimes we also forget to lock the door," I shrugged. "But it's never happened that I couldn't pull out in time."

"You really do manage to make pulling out sound heroic," she commented, giving my penis a slow squeeze, feeling it twitch and harden at the stimulation.

I puffed out my chest slightly. "Because it is. Only the strongest can overcome the overwhelming impulse to climax. Resisting such desires is like battling a fierce current."

Su Ah looked thoughtful at my words. A different kind of glint appeared in her eyes. She leaned closer, her breasts brushing against my chest. Her fingers gave another, gentler squeeze, her thumb caressing the swollen head of my erect penis. "Never happened before, hmm? Wait, does that mean... you've never finished inside Mia Unnie?"

"Yeah, actually."

Then again, it might have been Mia's intense desire for my seed within her that somehow prevented me each and every time.

Su Ah's breath hitched, her eyes narrowing into slits as she gazed at me through her dark lashes. "Oh, is that so? Are you implying my pleasure surpasses Mia Unnie's? Is that the insinuation, hmm~?"

My own arousal surged intensely, my cock spasming in response. This wasn't solely due to her provocative words, but more so because her hand on me was undeniably potent.

And yes, admittedly, a measure of satisfaction bloomed from the thought that she felt better than her own sister.

A fleeting, yet intensely perverted thought. Yet, I was reveling in every moment of it.

"He's quite honest, isn't he."

"Is he now?"

A smug smile played on my lips as I allowed her to continue her teasing, arousing touch. My focus blurred, a choked laugh escaping my throat as her skilled ministrations tightened their grip, making me harder by the second, until I was fully, exquisitely erect within Su Ah's grasp.

Her soft palm felt custom-made. I reached out, cupping her breasts with both hands. Capturing her right breast with my mouth, I tongued her nipple as her hand continued its caress.

A soft sigh of pleasure escaped her lips, and she writhed slightly beneath this dual assault, shifting closer to the sensation of my mouth.

"You... still haven't... ...answered."

I looked up at her, my vision likely a bit hazy from the intensity of her stimulation. It was a welcome, albeit torturous, development. "Answered what?"

"You... ah, never mind..."

Then, I kissed her, eliciting a moan and a wriggle. I found myself captivated by the interplay of her shyness, her quiet reserve, and her sudden naughtiness. My hand traced a path from her breast down to her stomach, and then further.

"Jae-il~"

She tensed, a shiver running through her as my finger brushed against her labia. The feeling was soft, moist, and undeniably inviting, a clear sign of her arousal, especially considering everything that had transpired.

What followed was a tangle of limbs.

We didn't go all the way, merely engaged in passionate kisses and mutual stimulation until the urge to rise and clean up the results of our second climax became imperative.

"At this rate, we might have to offer this one to the elements as well,"

I remarked, and Su Ah's laughter erupted against my chest. Within moments, her breathing evened out, deepening into a peaceful sleep. One of her legs was draped across mine, her hand still possessively curled around my semi-aroused length, as if she wished to carry it into her dreams.

As for myself?

I remained awake, unable to fully relax and drift into peaceful sleep, given our precarious situation in the wilderness.

I held my sister, for what felt like hours, until the storm receded from the summit, and a profound quiet settled over us.

On that day, I confronted the depth of my own desire for Su Ah.

And now, shackles, heavy chains, bound my spirit.
