Kang Ihyeon suddenly craved a glimpse of his sister's nipple buried deep in her flesh. He plunged his fingers into the pink mound at the center of her breast and began swirling them around.
Round and round, round and round.
"Ahhk?! W-Wait...! Ah, ah?! Aaaahhh??!!"
Yoon Se-ah felt a tidal wave of mind-shattering pleasure crash over her as her nipple—which had always been so shielded by her soft flesh that it rarely felt any external touch—was roughly rubbed and scraped.
"It's coming out? Just a little more...!"
He could see the bumpy protrusion at his fingertips gradually pushing through the flesh, bit by bit.
Like a sprout breaking through the soil, a pristine pink nipple emerged without a single blemish. As it peeked out, his sister's waist arched back with a creak, trembling wildly in the air.
"Where do you think you're going?"
He resumed thrusting his hips, which he'd paused to target her nipple, while his fingers gently scratched at the pink treasure still half-buried in her flesh, coaxing it further into the open.
"Kyaaah! Aaak?! Kh-Khuuuuuhhh??!!"
His sister let out a shrill, cat-like screech, her back bowing as if it might snap at any moment, convulsing uncontrollably. It was anything but normal.
"Kkh?!"
The already vice-like grip of her virgin pussy tightened even further, making it impossible to thrust anymore.
The ejaculation he'd been holding back surged up in an instant.
Gritting his teeth until they ground together, he forced his cock deeper, prying apart the narrow vaginal walls.
"O-Oh... Ooooh...? Oooohhh...??"
His sister wailed in a mix of disbelief and ecstasy, as if his cock had invaded somewhere it shouldn't, her reason leaking away in ragged moans.
"Sis, sis... I can't hold back anymore!"
His vision flashed white from the overwhelming pleasure, his mind refusing to function.
Driven by the primal instinct to impregnate the female beneath him, he slammed his hips forward until the tip of his glans popped against something inside.
He'd reached the end of her channel—the entrance to her womb.
At that moment, their convulsing bodies froze as if a switch had been flipped, every movement halting abruptly.
His balls contracted sharply, unleashing a torrent of thick, freshly brewed, scorching-hot baby batter in one go.
Spuuuurt!
"...!!!!!!"
The female, twisting her hips as if to buck off the man astride her belly, felt a gooey, lava-hot mass surging deep into her core.
Her teary violet eyes rolled back, whites flashing upward.
Her mouth, drooling rivers of saliva, gaped wide as if expelling every last breath in a primal scream.
"Nnghooooooooh!!!"
Spiiiish!!
With her cry came a gush tide from their tightly sealed coupling, squirting out in every direction through the tiniest gaps.
Yoon Se-ah's limp legs, dangling in the air, shot straight out and quivered violently, her toes curling inward.
The recoil was so fierce that the panties precariously clinging to one leg finally floated free, drifting down to the floor.
Spurt! Spurt! Spurt!
Twitch! Twiitch! Twitch!
Each pump of the cock buried deep in the female's depths drew a corresponding spasm from her body, as if in eager response.
Her doughy, overflowing breasts jiggled wildly, and at their center, the pink flower finally shoved aside the enveloping flesh to bloom proudly into the world.
The nipple—never before exposed to the light—stood erect in a soft yet vivid pink hue, mirroring the magnitude of her climax.
"O-Ohh... Kh-Kh... Khuu..."
Moans dribbled from Yoon Se-ah's lips in staccato bursts, as if her intelligence were draining away in real time.
Her saliva-slick tongue lolled out, rolling free as if the heat inside her mouth were unbearable.
'Ah, he's creampieing me...'
Lost in the hazy euphoria of her first-ever orgasm, Yoon Se-ah dimly registered the sensation of semen flooding her insides.
Each throb of the cock rammed deep in her belly filled her with a strange, addictive fullness—utterly alien yet intoxicating.
With no time to care about her thrashing body or her embarrassingly vulgar cries, the thread of her consciousness snapped.
Her bowstring-taut waist, quivering in midair, collapsed onto the sofa like a marionette with cut strings.
"Kkh...!"
In the midst of pouring every ounce of strength into his climax, Yoon Se-ah's falling hips shifted their angle.
Kang Ihyeon tumbled atop her in turn.
Her plush breasts cushioned his fall, and the dizzying heat radiating from her body, mingled with her intoxicating feminine scent, was utterly intoxicating.
Gloop! Glorp! Gloop...
Squish! Splat! Spuuurt...
Their inseparably joined sexes continued their fierce exchange, refusing to part.
Desperate to sow his seed even deeper, his cock churned relentlessly, displacing flesh, while her mound wept tears of arousal, forming a lewd puddle on the floor.
The two lovers, rigidly entwined, slumped onto the sofa together, utterly spent.
Yoon Se-ah's legs, twitching limply in the air, finally dropped into the slick puddle with a wet splat, ushering in silence.
Drip, drip, drip.
Only the periodic patter of their mingled fluids dripping from their union into the pool below broke the quiet.
"Haa, haa..."
Kang Ihyeon let out a deflating wheeze, like a man who'd exhausted every last drop of energy, and slowly pushed himself up.
Being his first time, he'd had no control over intensity or rhythm, no techniques to pleasure her—just raw, frenzied hip-thrusting.
Having poured it all into his beloved in such a short span, his limbs trembled like a newborn fawn's.
"Hoo, hoo... Hooo..."
Feeling the slick vaginal walls and folds clinging to his cock stirred fresh blood flow, but he decided to pull back for now and slowly withdrew.
Shluuuurp...!
"Nngiiih...?!"
A strange whimper escaped his sister's lips, and with a reluctant parting, he bid farewell to her stretched pussy.
Refusing to collapse in an unseemly heap, he steadied his legs and gazed down at Se-ah sis, sprawled across the sofa.
"Sis??"
"H-Hueee..."
Her sweat-soaked, disheveled two-tone hair was a mesmerizing mess all on its own.
Her face—streaming tears and drool, eyes rolled back with tongue lolling out—was so far gone it worried him.
Her ample breasts rose and fell with each breath, glistening with sweat in a profoundly erotic sheen.
Especially those nipples, now proudly erect and twitching atop the flesh that had once hidden them—he ached to latch on and suckle.
"Sis. You okay?"
Kang Ihyeon's concern stemmed from her lower half, which convulsed like she was having a seizure.
As he moved to gather her splayed legs, her plump pussy gaped open on its own and vomited a flood of semen.
Gloop! Glorp! Glorp!
The creamy white load cascaded from between her thighs, trickling down her sweat-slick inner legs to splatter into the arousal puddle below.
Clear fluids mingled with the opaque seed, releasing an indescribably erotic musk.
A decadent blend of musky night-bloom and sweet feminine essence.
"U-Unnh... N-No. Hold back."
He'd just cum, but one look at Se-ah sis's wrecked form had his cock stiffening anew, as if on command.
He wanted nothing more than to mount her right then and pound away like a beast in heat—but sex was consensual.
Forcing it for his own satisfaction would be coercion, so he clenched his jaw and endured.
After tidying her limp limbs on the sofa, he offered his lap as a pillow for her comfort.
His slick, fluid-coated cock ended up right by her face, but whatever—who cared?
Eventually, he'd ask her to suckle his precious tool, and she'd indulge him cutely. Sighing in deep satisfaction, he exhaled heavily.
"Haaaaah."
A wave of bone-deep fatigue crashed over him, the relief of completion mixing with exhaustion.
'Ah, I can't hold out anymore.'
Come to think of it, after three sleepless days tending his father's funeral, he'd charged ahead like a beast.
Kang Ihyeon's eyes lost focus, his head lolled forward, and he drifted off to sleep.
Thus, the two lovers' tender yet intense first time drew to a quiet close beneath the warm glow of dusk filtering through the window.
