186 — The Comet

Su Ah's POV:

Cold bit first at her skin, then burrowed into her bones. It crept from the stone floor beneath her.

Morning, she dimly thought. Only it wasn't morning. The cave was darker than when she fell asleep earlier.

The second thing she registered was the heat. A solid wall of muscle and warmth pressed against her back. An arm rested heavily over her waist, pulling her close. Another body's breath fanned the back of her neck. A shiver went through her, and she found herself pushing backward. She slid into that warmth until not even a sliver of air separated their skin.

Sleep began to dissolve around the edges of her consciousness like fog lifting from a pond.

And with the awakening came the sensation—not pain, but discomfort. A lingering awareness of how she'd been stretched and taken. It had been an ache when Jae-il penetrated her the first time. Nothing sharp, just a slow, pleasant burn of entry. Then his thick girth had awakened every nerve inside her sheath.

A delicate fullness remained now that he wasn't inside her, almost as if her channel missed him already.

Even her vaginal walls twitched. She inhaled, clenching them experimentally and sighing with pleasure at the ache this caused. Then she relaxed them, and they squeezed down around emptiness, milking that ache with every subtle movement and coaxing an aching sort of throb from her overused, sensitive inner flesh.

Somehow, Jae-il and his manliness were making her vagina fucking purr.

Filled, then empty... it was addictive, her sheath seemingly clinging to the ghost of him inside her.

Behind her, her younger brother let out a long, groggy sigh. Her neck tingled as warm breath spread down her spine, her brother's forehead grazing her nape. Her eyes fluttered as she vividly remembered that very same sensation, of him panting, groaning, on the absolute fucking edge of exploding, right into her ear.

And she recalled perfectly how his words, his naughty, brutal honesty during the act that made her feel incredibly ashamed and mortified, yet so incredibly aroused in that moment. Like, what the fuck? Was she more of a pervert than she already was?

Because having the truth being spat out of those beautiful lips of his had the effect of turning her body into a melting pot of bubbling liquid magma. Who'd have thought Jae-il had such a side to him?

Maybe he enjoyed that taboo aspect of it too? Once you embrace an unlawful act, your capacity for more perversion grows infinitely. She mused inwardly.

Shame flickered. Briefly. She was his sister—his older sister by years, who should know better, who should guide him not lead them both here. But the memory of Jae-il's final guttural groan as he spilled himself into her—God—all those considerations dissolved like the rainfall had dissolved everything else outside their sheltering rock.

How could she not want more of that bliss when she felt it slip and ooze out from her.

She'd live with the guilt and shame if it meant feeling that intense high again and again. And Jae-il wanted her too, right? If they'd go to hell for that, they'd go together.

It took an immense amount of self-control to keep from turning around and climbing him like a tree. Instead, she laid there, hyperaware of her younger sibling's hand resting against her stomach. His cock—not so little anymore—straining against the back of her thigh.

A movement behind her broke through her thoughts. Jae-il's body stirred. "Noona, are you awake?"

His words lacked the typical drowsy slur. He must've been just lying. "Jae-il... you didn't get any sleep at all, did you?"

A low, sleepy chuckle that sent vibrations along the curve of her back. "I much preferred watching you snore like a truck driver."

"Snore—like a truck driver?!?! What the fu—Are you—"

She managed, affronted, her spine suddenly stiff as a steel rod. But a palm pressed her flat again. "Stop. Move. Your ass feels way better." He cut her off.

"......"

She huffed, squirming against her back. There was this telltale pressure at her upper thigh, a delicious sort of friction that didn't relent and seemed to burrow into her asscrack, seeking—well, something.

"Is your morning wood that thirsty, hmm?" She teased, flushing a little. "Not satisfied from last night?"

"Ah, Noona... I can last all night and well into the day. My thirst is never quenched."

And they both could confirm he was being brutally honest about the second part as his virility surged with renewed vigor right between her buns. She smiled. "Incorrigible, Jae-il."

"Right back at you, Noona. You're totally a bad influence on your poor little brother, leading him to a remote mountain where he could easily and most irresponsibly, end up fucking you within an inch of your life while you beg for more. Tsk tsk. Just the type of woman I should be staying far away from."

She couldn't help a small huff of amusement, even as her heartbeat rose a little higher. "Is that supposed to be the same little brother whose massive dick is grinding on the small of my back? In that case, should I consider myself a victim of rape? You raped the morals out of your good and righteous, poor noona?"

Jae-il burst out laughing, and she stifled a small chuckle of her own. She was also starting to feel how uncomfortably sweaty and grimy she was; they had been rolling and wrestling around for a while, getting all dirty without a chance to properly get themselves cleaned.

"Yikes." Was her little brother's witty remark, but even in that word she sensed a glint of mirth in the tone.

Their fingers found each other beneath the covers, interlocking loosely. A comfortable silence passed between them as they lay spooning in their cocoon.

Su Ah turned fully in his arms then, careful of her sore places, to face him properly.

In this light, she was more conscious than before of how handsome he truly had become—not childishly cute or teenager handsomeness but the sort of appearance that would make people glance twice with no apparent shame.

If Jae-il could walk down the street today, all the teenage girls' eyes would probably be popping out.

'Mine.' She found herself thinking with extreme satisfaction and elation. 'He's all mine.'

Like, if she wanted to, she could kiss him right now, she could touch him, could do whatever she damn wanted. She could grind into him until he lost his shit and penetrated her. Right fucking now.

But, at the same time, it was scary... how alluring and exciting this newfound freedom was.

Temptation proved too powerful. Before she knew what was going on, she was rolling onto her side, scooting close enough that Jae-il was forced back to prop his torso up with an elbow. She giggled as he pretended to pull back with an alarmed look, and giggled some more.

This is what Jae-il brought out in her—happiness, real, genuine joy she hadn't experienced before—like, ever.

When was the last time she had smiled and laughed so freely, like a child?

Maybe, in some deep, buried place, Su Ah was a very lonely, wistful girl.

"Ahhh, Noona is the worst... taking advantage of her poor, pure, unassuming little brother. So despicable and unethical." Jae-il moaned pitifully. She smirked.

Her arm tightened around his shoulder in a hug and her mouth latched onto his. It wasn't meant as something lustful or erotic, rather more a loving greeting. She continued to kiss him, peppering every inch of his face she could reach.

His facial structure, his cheeks, jaw and nose, the perfect arch of his eyebrows and even the curves of his lips—Su Ah worshipped them with her lips. Jae-il wrinkled his face and tried to fend off her mouth with the back of his hand. "Ewwww, Noona."

"Ewww!? Eewww what?!" Su Ah couldn't stop smiling. "Didn't seem like eww earlier!"

Jae-il chuckled as he stretched an arm and grabbed his smartphone to check the time, still too immersed in their playful banter. "You can't do these kinds of things to your little brother, or I'll be scarred for life, Noona!"

"Since when has Jae-il ever been scarred, mmh?"

"Oh, damn it's actually quite late. 9 PM already."

His response was so unexpected Su Ah had to blink.

"9 PM? Really?" She didn't realize she had slept in for so long. When had it been raining? Almost five in the afternoon, probably, when they decided to hole up in this cave. "Wait... the storm has passed?" She couldn’t hear anything from outside.

Jae-il pulled himself into a cross-legged position, stretching out his arms as he twisted his upper half right and left with an audible pop.

"A while ago." He grunted, getting to his feet. She watched, enchanted, as the lean, toned lines of his naked torso flexed and moved beneath his smooth, nearly poreless, pearly white skin. "You were so fucking out of it."

Her face and neck warmed, then her eyes lit up. "There's still time, Jae-il! The comet! We can still catch it!" She sprung into motion, running for her clothes, which while still quite a bit wet, were still wearable.

Jae-il was already strapping his pack to his body by the time she had pulled on her wet-clothes and joined him. It was quite dark by the time they left the cave and stepped out into the cold mountain air, the night air clear and crisp.

Above them, a perfectly clear and pollution-free night sky.

Su Ah was mesmerized as she stood there, next to Jae-il, beholding the vast expanse of the heavens.
