182 — Under the Stars IV (Slightly NSFW)
Su Ah's POV:
Jae-il blinked. He reached a hand towards the sleeping bag.
And paused.
If he lay down and held her close, their shared heat would thaw his own chilled flesh as well as hers.
They could warm each other and then keep the warming throughout the night, huddling close, safely ensconced in the warmth of their bodies and the bag, and, perhaps...
... they would be even more intimate.
Su Ah still didn't turn around, but Jae-il heard the slight tremor in her breathing.
"Alright, I'm coming in, Noona."
She scooted deeper into the bag, tensing.
As Jae-il slid himself in, however, all she felt was the press of her brother's body.
Su Ah's world narrowed to that single, heartstopping point of connection.
"You're shivering." He murmured, his breath licking across the sensitive skin of her neck.
She wasn't—it was desire disguised as tremors—but she just nodded, clutching the fabric of the bag. Jae-il's arm slid around her waist, pulling her snug against him. His hand came to rest on her stomach, undeniably firm yet strangely not intrusive. It just rested there, comfortably.
Yet the small, delicate strokes of her brother's thumbs along the curves and dips of her waist, navel and hips sent her blood pumping at a frightening rate. She prayed her heart didn't give them both away. Ah, who was she kidding? As if Jae-il didn't already know what was happening down there.
"... hng..."
She gasped, fingers clenched and holding back her breath at the same time.
His fingertips didn't need to go any higher or lower for her to lose it. Just this gentle concern in which he moved his fingers. There was nothing sexual about it, at least that didn't seem to be the intent behind those slow circles.
Still...
Jae-il nosed into her hair, exhaling, before wrapping his arms fully around her and pulling her back firmly against him.
Their bodies connected from shoulder blades, to shoulder blades, to calves, to legs...
Su Ah sucked in another sharp inhale, trembling and frozen.
So warm. So unbelievably warm.
So much, that her knees felt weak.
Minutes passed in relative silence. Su Ah could hardly hear the thunderstorm outside over the pounding of her pulse in her own ears, and the rapid rise and fall of her chest. "Haah... haaah..."
"Are you cold, Noona...?"
"... nnnh."
She didn't trust her voice, not with how her brother's breath hitched when his fingers inadvertently slid higher up.
Su Ah tried to think—not that there was much to think about. And her body, apparently, had already made up its mind.
She shifted, and then moved again. An exquisite slide back until—
Oh.
She felt it then, hard and insistent, pressing against the cleft of her pantie-covered butt. Jae-il tensed sharply against her, a hiss leaving his lips.
Even more warm shivers erupted beneath her skin at her brother's husky groan.
Su Ah's eyes grew wide. The hot, smooth swell of flesh beneath her ass reared tightly against her brother. She bit her bottom lip, eyes screwing shut as she carefully, ever-so carefully, pressed backwards, inch-by-inch, her skin and silk panties caressing a firm, rapidly growing ridge.
His hips shifted, nudging closer and—
Oh, gods! Su Ah groaned softly into the crook of her arms, a harsh intake of breath following in its wake.
Su Ah squeezed her thighs together, whimpering. She burned at her brother's unconscious bucking, even more so when Jae-il grunted deeply, pressing his hips into her once, twice—
The sensation made her throat close, eyes blur with tears, the contact sending pleasure up her spine.
A sharp inhale, followed by the most exquisitely lewd and breathy moan. Jae-il's fingers dug into the soft flesh of her stomach, pulling her impossibly closer.
"Jae-il..." Su Ah didn't know where she found the courage to speak, or what sort of spell her brother was casting upon her as she willingly grinded herself back and forth and, fuck, it just felt so good. "My panties... I... we should probably remove them. J-Just to ensure there's no clothing barrier between us. Just... so we can stay warmer..."
There. That sounded logical and normal and not like a sister shamelessly offering herself to her brother.
"... I agree." He said hoarsely. And slowly, ever-so slowly, the tips of his fingers sneaked along her flesh towards the strings holding her last defense together.
One quick yank and her panties were no more than a piece of silk trapped at the bottom of her sleeping bag.
He didn't waste any time removing his underwear either, tugging them down until he harshly kicked them off to join her own at their feet.
The sudden rush of the hot, bare expanse of her bottom directly meeting the rigid girth between his legs had her shaking so hard, and yet craving his touch just as desperately.
She eased herself further back, felt the unmistakable arousal straining against her bare bottom. Then her hips bucked as Jae-il's fingers crept lower down, towards the apex of her thighs.
She let out a ragged gasp. His touch made her hips stutter back against him again, and she pressed her thighs together to relieve some of the sudden ache that bloomed there.
Jae-il bucked forward against her ass and pulled another languished groan from her lips. His cock was nestled tightly between her cheeks. She wiggled. Jae-il pressed back. His fingers tightened on her stomach and his hips followed her retreat with a forward thrust.
A soft whimper she couldn't quite swallow down escaped her lips.
There was no actual need to hold her voice down, so maybe it was just that tiny slice of vanishing pride still left within her that didn’t want him to know how much this simple action of grinding was getting to her.
Her eyes were in a daze.
His mouth found the curve where her neck met her shoulder in response, a trail of kisses that made stars explode behind her eyelids.
She arched into his touch shamelessly. All pretense gone now.
Jae-il knew, and yet there wasn't even the slightest hint of rejection from him. His hands only became firmer on her hips, gripping. Tightly. Pulling her back into the motion of grinding against him.
Now both their voices were clear and audible within the confines of the cave. Moans and pants, gasps and shuddering breaths.
His length was rigid, sliding firmly in the crack of her ass, the pre-cum smearing between her cheeks—and like a river, converged into the ocean between her thighs.
She was so moist down there she could hardly believe all of this wetness came from her.
No words were spoken as Jae-il slowly eased one arm under her, coming to rest on her soft mound. She tried not to buck. Failed, in a most obvious way. Her hands clasped firmly over his, while his other one spelunked down the very stormy weathers on her slick folds.
"I'm sorry..." She apologized. And yet, the pace of their hips didn't falter for a single moment, not until her breath hitched as his fingers moved and grazed that one spot at her core that felt impossibly slick and throbbing and so sensitive she could barely keep still, rocking gently against his digits, and his cock.
"For what...?" Jae-il was panting right into her fucking ear. Oh God!
"For... haaaah... a-all of... hnng~... this..." Su Ah managed breathlessly.
This?"
Su Ah whined.
Gods.
"Look down."
Her lashes fluttered at his rough command, her chest moving up and down rapidly.
When did this escalate from innocent body-warming measures into something she didn't dare to call a proper intercourse?
Why were her legs suddenly so, so incredibly, deliciously sensitive?
Then again, it wasn't like she hadn't used the comet as an excuse be as far away from the rest of the world as they could. She had planned this for the sole purpose of doing this with him. The apology was just to make peace with her conscience.
Still, she couldn't help feeling as if she was using him—her own brother.
Su Ah wanted this, yet...
Jae-il swallowed the sentiment and crushed his mouth to her earlobe, tracing a soft path of kisses down to the soft spot beneath her ear that had Su Ah gasping helplessly.
She whimpered softly as he continued. His hips remained in perpetual, slow thrust.
"I-I'm sorry..." She cried, the movement making her jerk and rut even further into his grasp. Her entire body convulsed. Su Ah went rigid, arching sharply. "I-I'm using you!"
But her hands clenched over his. Gripping tighter, she urged him forward and rolled her hips up into his palm, and the waves of a pleasure that felt so fucking sinful, sent her toes curling, her head spinning.
Faster and faster the sensations rolled through her, and with Jae-il's hips moving, he drew pleasure and tingling pressure over the tight little nub between her legs again, and then over, and over and over again in an unrelenting cycle.
Her mewls evolved into low, keening noises as his pace picked up. She matched the intensity with the undulating of her hips, trying to drown out all thoughts except for the one consuming her senses—that she couldn't stop chasing that dark, beautiful abyss no matter what she did.
Jae-il's harsh pants next to her ears mingled with his hoarse, rumbling moans. She didn't care; there was no part of her that felt capable of reining in her instinct anymore.
With tears in her eyes, Su Ah squirmed. And in that instant, his pace took on the frantic urgency of a beast on the brink of an extinction-inducing climax. "Jae-il, J-Jae-il!! Oh~!!"
Fuck.
The tremor coursed throughout every fiber, every pore of her being.
She arched her neck and reached an all new high, one that had her grinding against him harder. Her muscles clenched, and rippled and her belly jerked forward. Jae-il's pistoning hips stuttered to a halt as he focused all of his energy on stimulating the same sweet spot that had her quivering so helplessly against him, and sending her over the edge with guttural sob.
Oh god, god, gods!
She had missed this so fucking much!
Su Ah went bonelessly limp against the sleeping bag, eyes glazed, sweat pasting tendrils of hair to her face.
Her lips trembled as the sensations tapered and receded until she was cognizant of her surroundings. The sleeping bag. The cave. Only now was the racket coming from outside registering in her mind.
"J-Jae-il...?" Her whisper was hesitant. Shy. Embarrassed. She squirmed until she found the perfect position to gaze straight up into his face, and then down at his painfully hard, throbbing member.
He hadn't found release.
His eyes bore into hers. Their hips were still gently undulating.
"... Noona..." He breathed out, eyes darkening.
Su Ah snapped her gaze away as tremors, once again, ran through her body. His cockhead was still so cozily wrapped between her twin buns, pulsing, battle-ready—all Su Ah had to do was give the command.
"Jae-il..."
She couldn't look at him and say it. But if not now, then when? They were naked, hidden away, in an earthy pocket protected by the elements. No one would be passing by. No one would be hearing her say the cursed words. Most importantly, no one would know that here, in this thousand-year-old cave in a small-no-name mountain in the middle of a storming rain, that this little incestuous couple had taken the first steps.
"Jae-il... take me."
