RE: Keep it in the Family (Secret Class) 184 — Under the Stars VI (NSFW)

Su Ah's POV:

With her hips arching higher, Su Ah clenched and pressed, a wave of shivers cascading down her body with every deep thrust of his firm shaft. The sheer sensation of being filled repeatedly, her nerve endings alight as Jae-il moved in and out of her, was nearly unbearable. They were actually doing it. They were truly making love.

A low growl of pleasure rumbled from him with each deliberate, grinding motion that came and went. Su Ah, her hips rolling, seemed to chant inwardly. The deep, carnal sounds escaping his lips caused her spine to curve upwards. He tightened his grip on her hips, drawing her closer, and continued his steady rhythm. Su Ah let out a broken sob.

She had never even dared to imagine such a thing could happen, let alone experience it with Jae-il—her own little Jae-il. "Ahnn~!!" Su Ah cried out as his length filled her completely. "Jae-il... please don't stop," she managed to gasp.

Even as her own ecstasy threatened to consume her, Jae-il offered no further words, only soft, panting breaths and a gaze that was so exquisitely gentle. "Jae-il.... oh~..." Su Ah choked out as another potent surge coursed through her.

He growled and seemed to fold into her, shifting a hand to brace beside her shoulder to quicken his pace. His eyes were wide open, meeting hers. He watched her writhe and feel, even as her hips spasmed, rocking and trembling. He thrust into her with a force that was not precisely rough, yet so intensely deep, she felt as though his cock was striking directly at her womb.

"God, Noona... you look so incredibly hot when you lose yourself for me," he breathed into her ear, panting and gasping. "Can you even see me?"

No, she couldn't. Her vision blurred, her gaze fixed upwards towards the cave's ceiling, seeing nothing. All senses and consciousness were submerged beneath a rising tide. Perhaps it had ascended beyond the mountain peaks, soaring into the oppressive darkness far above the heavens, the presumed abode of God—and was He watching them right now as her own sweet brother defiled her?

Did He see her at all, her form and senses fading away? Was God appalled, perhaps, by her and her actions? Or was He amused by the fancies of a wretched mortal? Would this be recorded somewhere, perhaps a brief mention, in some divine ledger regarding the curious activities of mortal humans down here when overcome by lust and acting on primal urges?

Maybe. Maybe not.

Su Ah had no further moments to ponder such questions, nor the capacity to worry about any divine spectators. The sensations she experienced felt nothing short of heavenly. Something so exquisite could not possibly be sinful. The very notion of it being anything less than miraculous struck her as absurd.

It felt so good. It was good, so very good, far too good! She couldn't contain the soft sounds escaping her, and the sheer pleasure made her cry out and scream, half-pleading with him. He chuckled, his rhythm deepening, accelerating, lengthening, striking harder until Su Ah was writhing uncontrollably.

"Ah! Jae-il! Jae-il!"

"You like that, Noona?" Jae-il murmured.

He continued, his hips snapping powerfully against hers—

"Answer me, Noona," he repeated, his voice firmer this time, and she shivered at the commanding tone. "Look at me when I speak to you."

Su Ah's world snapped back into sharp focus. She met Jae-il's gaze, her breath catching in her throat. Tears welled in her eyes, a mixture of intense pleasure, a sharp sting of pain, and an overwhelming emotional flood. "I—I like it, Jae-il... ahn~ please don't stop!"

Jae-il's face was a tableau of intense concentration, yet she discerned a flash of triumph in his eyes, and a hint of playful scorn as he thrust into her with enough force to make her body bounce upon the thin sleeping mat. He brought his lips close to her flushed ear once more. "You're just like Mia Noona, aren't you? Both disgusting perverts craving my cock in your slutty, willing little cunts."

Su Ah felt her pulse quicken at the shockingly vile words escaping his lips, the heat inside her intensifying, spreading upwards like flames along her spine. The muscles within her contracted and spasmed. "Yes," she heard herself respond, her voice reduced to pathetic whimpers.

Had she been slightly more sober, perhaps, a touch more composed, Su Ah might have flushed with shame or lashed out at his scandalous, crude remark. But with her entire being consumed by the effort to satisfy this demanding, relentless lover, all she could manage was a high-pitched, reedy moan that sounded more like a squeak than actual speech. "J-Jae-il... s-slow d-down, ahn~!! If you fuck me like this, I'll c-come..."

His pace didn't falter even slightly; instead, he met her groans with a resonant growl and intensified his efforts. Su Ah's ankles responded swiftly, digging into him as she wrapped herself around him with her arms and legs.

The sleeping bag seemed to convulse, struggling to contain the frantic rhythm and fervent movements now colliding in unrestrained passion. Su Ah, her senses already dissolving, found herself unable to resist. She clung tightly to his form, her hands grasping at anything she could hold onto—his hair, his back, the nape of his neck, his forearms. "Ah... oh, yess~."

"Noona, you're squeezing me quite intensely. Does it excite you more, knowing you're being taken by your brother~?" A strained chuckle escaped him as he shifted slightly, his grip tightening on her hair.

With a sudden, decisive motion, he pulled her face upwards, initiating a forceful kiss that left her no choice but to inhale the very air he exhaled.

"Look at how slick you are. Gods, it feels so hot and wet." Her vision swam, the building tension in her core threatening to shatter. "I can't tell who's the bigger freak. You, for being so damn eager for this cock. Or Mia Noona, for raising you with her twisted ways."

He then let out a deep groan into her mouth, his moans and gasps stealing the air she desperately tried to draw in.

"Y-You're..." Su Ah began to stammer, but Jae-il's actions cut her off. "Oh god... Jae-il~ ah! Nngh, ahh~!!"

She couldn't even articulate what she might have wanted to say. Everything he spoke held a certain truth.

"Then again, perhaps you've always been this way..... I won't last much longer like this, Noona..."

Su Ah cried out his name, her body clenching with an intense, almost unbearable tightness, nearing the brink. With just a few more powerful thrusts, her eyes fluttered shut as if under a spell. A profound, electrifying sensation coursed through her with each punishing movement from Jae-il.

"Jae-il~~!!!"

The climax was imminent, delivered with forceful intensity as his hips slammed against hers repeatedly, without a moment's hesitation.

And then, a moment later, her vision contracted, sharpened, and finally blurred. All awareness of her surroundings vanished, replaced entirely by him; his presence was all-encompassing, leaving nothing else—the entire universe seemed to converge on her, on him, and on Su Ah...

Finally, her cries escalating as her mind fragmented, her core tightened and constricted like a serpent. A colossal orgasm surged through her, eliciting tears, screams, shudders, and gasps. Her toes curled, and her knees would have buckled if not for Jae-il's firm hands holding them apart, spreading her wide.

All she could manage was a whimper and a wriggle as waves of pulsating ecstasy washed over her body.

Her body continued to convulse even as her spirit felt utterly broken.

Her face flushed so deeply she felt her skin might crack.

Jae-il propelled her deeper into the throes of pleasure. He drove relentlessly, prolonging the agonizing sweetness of the orgasm, extending it beyond what seemed humanly possible, pushing her senses to the absolute limit until her head spun.

And then, with a brief grunt and the words, "I'm cumming, Noona. Hah~ fuck, haa... fuck!" followed by a powerful shudder that ran through his muscular body, she felt a surge of heat filling her from within.

Her eyes snapped open, her body instinctively drawing closer to the source. Her nails dug into his hips, locking him in place. She shuddered around him as warm torrents filled her completely, overflowing, his cock pumping out surge after surge as if intent on reaching the very depths of her womb, thoroughly coating it, and then painting her insides with a pure white finish, obliterating every trace of the blood he had just shed and replacing it entirely.

Su Ah's eyes widened impossibly as she experienced a distinct, overwhelming orgasm that convulsed through her core, ignited by the deliciously hot fluid flooding her. Jae-il groaned, his hands pinning her down, trapping her for each subsequent throb as he reached his own climax.

"God, god, ahhhn~ hah~!! Aaaah!! Jae-il..." she mumbled into his hair. "Oh, goodness. There's so... much..."

Indeed, a portion of that intense heat had escaped from where they were joined, staining the fabric of the sleeping bag.

"Yeah. There is," came his weary reply, just as her trembling core pushed out his receding erection with a final squeeze, a generous mixture of lubricant and his sticky release splattering, leaking, and spreading across her underside.

With that, Jae-il's back arched one final time before he slumped forward, exhaling heavily, pressing her against the mat and himself as their heaving bodies settled into the quiet aftermath.

Somehow, her little brother possessed enough remaining strength to sit up, unzipping the sleeping bag slightly to create more room.

He looked at Su Ah, who lay prone on the mat, arms outstretched, her hair a disheveled mess. Her lips remained slightly parted, her breasts still tingling from the sudden chill, her skin glistening with a thin sheen of sweat.

A brilliant crimson stain traced a perfect line from her pubic mound downwards, painting her thighs. A mixture of seed, cum, and blood continued to ooze and trail from her thoroughly used core.

"Fuck..." Jae-il cursed, his chest still heaving, muscles twitching from the lingering effects of his intense climax. "Noona...?"

"Hmm?"

"Is it a safe day?"

"......"
