Their bodies clung together with fevered desperation. Ai's nails scraped down Shin's back as he thrust into her harder. He lifted her hips again and sat back on his heels, pulling her onto his lap with her legs arched high above her, feet pointed toward the ceiling. The angle made her cry out, her voice cracking as he hit deep, untouched places.
"O-Onii-chan—this is…!"
He smirked, grinding into her slow and deep, watching her eyes flutter, her mind drowning in the pleasure.
"New angle," he murmured, "You like it?"
She couldn't speak—only moaned in answer.
Then he lifted her entirely, shifting into a standing squat at the edge of the bed, his arms locked under her thighs, her back arched in mid-air as he pounded upward into her. Gravity made everything sharper—every thrust, every bounce, every pulse of heat between them.
"Ahhh—you're a beast today—!" she whimpered.
He grinned, pressing his lips to hers briefly. "You love it."
She did. But in a brief moment of hazy breath, her lips parted, and she whispered, "Onii-chan... you have to say yes."
He slowed, eyes narrowing curiously, still buried inside her.
"Say yes to what, Ai?"
"To Rika. You have to say yes if she confesses again. Like she did this morning."
Shin blinked. Then smiled—genuinely. "You really want that?"
She nodded, wrapping her arms around his neck, lips brushing his ear. "I want all of us to be together. Forever. So promise me."
He kissed her deeply, his tongue curling around hers, then whispered, "Okay. I promise."
Ai's heart fluttered, her smile drunk and blissful. But she wasn't done.
"Also... Haa-Onee-chan. And Yuki-san. If they confess too… you have to say yes."
Shin laughed, a low, deep sound full of affection and lust. "What a greedy little sister I have."
"Promise me," she said, voice rising as he began to move again.
"I promise. To all of them. If they want me—I'll say yes."
Her smile widened, and she opened her mouth to say something more—but then gasped as he suddenly pulled out.
"Eh—? Onii-chan—?"
Without warning, Shin pressed the head of his cock to her tight, untouched hole and shoved forward.
"Wai—AHHH!"
It went in.
No preparation. No warning.
But Ai's body, already used to his tongue from earlier—four, five times throughout the day—reacted instantly. Her back arched, her mouth fell open in a silent scream, and her legs shook violently.
"O-Onii-chan! It's—it's in my butt—!" she cried.
"It is," he growled, voice feral. "You teased me too much today… I need this."
He held her hips and began to thrust. No mercy. No hesitation.
Ai's body burned, mind overloaded from the sudden shift. The pain and pleasure blurred into one storm of sensation as Shin's length filled her in ways she had never expected.
She reached out blindly, grabbing the sheets as he continued to take her, sweat pouring off his body onto hers.
"I'm going to stretch this hole until it remembers only me," he whispered hotly in her ear.
"Y-Yes—yes, Onii-chan—!" she sobbed.
Shin didn't slow down. If anything, he got rougher, more primal.
He shifted his grip again—his hands sliding lower, locking around the backs of Ai's knees—then lifted her until her entire lower body was suspended in the air, her torso dangling, only his strength keeping her aloft. Her toes pointed toward the ceiling, her spine curved in a perfect arc, breasts bouncing wildly with every violent thrust upward.
The new angle made her scream.
"Aaahhh—! O-Onii-chan—! It's—it's too deep—!"
Her tiny, clenching hole was stretched impossibly around him, spasming with every pump of his cock. Gravity pulled her down onto him as he rammed upward, their bodies slamming together with slick, obscene sounds.
"You can take it," he grunted, biting into her shoulder hard enough to leave a mark. "You're my good girl. You're mine."
Ai's brain short-circuited under the intensity. Her hands flailed for purchase before she grabbed onto his arms, nails digging into his sweat-slicked muscles.
Shin kept going.
Not satisfied with just this, he moved again, still inside her—dropping onto his back on the bed and flipping her over so that she was now straddling him in a reverse cowgirl, her back to his chest, his cock still buried impossibly deep in her ass.
Ai sobbed, the shift forcing him even deeper.
"O-O-Onii-channnnn—!"
"Ride me," he growled against her ear, one hand smacking her ass sharply, making her squeal.
Ai, half-crazed with sensation, braced her hands on his thighs and began to move, bouncing shakily up and down on him. Every time she lifted herself even a fraction, gravity and his strength pulled her back down, spearing her over and over.
Her whole body trembled. Her belly bulged slightly from the sheer force of his thrusts.
"Faster," Shin commanded.
She obeyed—what little strength she had left focused on moving, even as tears blurred her vision, even as pleasure threatened to break her in half.
Then—another shift.
Shin bent his knees, planting his feet flat on the bed, and thrust up from below while holding her hips steady. Every upward drive hit something devastating inside her, making her scream out loud, her voice breaking into sobs.
The world blurred into heat and noise and frantic, sweaty motion.
Ai felt herself spiraling—losing control completely.
"O-Onii-chan—I'm—I can't—!"
"Come for me," he snarled, pounding harder. "Come while I'm deep in this hole."
And she did.
Ai shattered, her orgasm ripping through her with blinding force. Her entire body seized, her hole clamping tight around his cock, milking him as she screamed his name, her voice raw with ecstasy.
But Shin wasn't finished.
While she was still trembling, he rolled them again, pinning her flat against the mattress with her ass raised high, her legs spread wide. He loomed over her, pushing even deeper somehow—his cock hitting places that made her vision white out.
"Still conscious, Ai-chan?" he teased darkly, breath hot against her ear.
"Aahhh—! O-Onii-chan—no more—!"
"Yes. More," he growled.
He hooked one of her legs around his shoulder, folding her nearly in half, and slammed into her with brutal, relentless thrusts.
The position was impossible—her body bent so sharply she could barely breathe—but it only made the sensations stronger, sharper, more overwhelming.
Ai cried, sobbed, moaned—her body betraying her completely as a second orgasm began to build immediately.
The sounds of their bodies colliding filled the room, obscene and wet and feral.
Sweat slicked their skin, the scent of sex heavy in the air.
Shin leaned down, pressing his chest against her back, one hand tangling in her hair, the other gripping her hip as he pounded into her mercilessly, his cock slamming deep into her over and over.
He growled words into her ear—dirty, possessive, loving.
"My sweet little sister… taking it so good… Fuck—Ai-chan, you're perfect…"
Ai couldn't speak anymore—only sobbed and gasped and pushed back against him instinctively, her body desperate for more even as her mind reeled from the intensity.
She was wrecked.
And she loved it.
Then Shin did the unthinkable—he lifted her again, this time standing with her body still impaled on him, one hand under her ass to keep her in place, her legs dangling helplessly.
He turned toward the wall mirror at the side of the room and forced her to look.
"See yourself," he growled, voice feral. "See how beautiful you are like this."
Ai's blurred gaze focused on their reflection—on the image of herself dangling limply from her brother's cock, her body marked with bites and finger-bruises, her skin flushed red from overstimulation.
She moaned brokenly, burying her face in his neck, shame and lust crashing together in a breathtaking storm.
Shin fucked her standing like that, hard and fast, the sound of slapping skin echoing through the room, Ai's cries growing higher and thinner with every brutal thrust.
She came again.
And again.
And still, Shin didn't stop.
When her body finally gave out completely, when she hung limply in his arms, he carried her back to the bed and folded her in half once more—her knees pressed against her chest—and fucked her into the mattress.
By the time he finally roared her name and emptied himself deep inside her ass, Ai had lost count of how many times she'd come.
She sobbed weakly, trembling all over, feeling every pulse of his release inside her.
And when he finally pulled out—slow, deliberate, savoring the sight of her gaping, dripping hole—he gathered her into his arms, kissing her forehead tenderly.
"My beautiful Ai-chan," he whispered. "You're incredible."
Ai clung to him weakly, tears streaming down her cheeks—not from pain, but from overwhelming love and pleasure.
"I love you, Onii-chan," she whispered hoarsely.
"I love you too, Ai," he murmured back.
And he meant it with every fiber of his being.
