The room was heavy with silence—thick, slow, and trembling, like the hush that follows a violent storm. The air still carried the scent of skin, salt, and something darker: surrender.
Yuki had long since collapsed against the mattress, eyes fluttering shut, breath soft and even, a faint flush painted across his cheeks. His body, once wracked with wave after wave of pleasure, now lay still—only the occasional twitch in his fingers betraying the aftershocks that still rippled through him.
Aiko wasn't much different. Draped across the pillows in her own glow of sweat and satisfaction, her legs curled slightly beneath her, her lips parted in a dazed smile as sleep began to claim her.
But Ai wasn't done.
Her hand moved slowly between her legs, fingers slick with her own desire, eyes locked on the scene unfolding before her—just a few feet away—where Shin now hovered over Rika.
And Rika... trembled.
Her body quivered under Shin's touch, already marked by anticipation and something far deeper—devotion, maybe. Fear. Hunger. All woven together beneath her skin like fire and silk. She lay on her back, her brown eyes wide and fixed on his as he loomed above her, his breath hot against her lips.
He kissed her.
And not gently.
It was a claiming—tongues and teeth, hands finding bare skin and soft curves. Rika arched into him, her breath catching as his mouth found her neck, then lower, dragging fire down her chest. Her back lifted off the sheets, gasping when his tongue flicked against her nipple, swirling in circles that made her hips buck instinctively.
"Shin—" she moaned, but he didn't stop to answer.
His hands were everywhere, sliding down her sides, gripping her thighs, pulling them apart with that familiar confidence that made her heart race. She was so wet—hot and Shin could feel it around her dick.
Ai's breath hitched from across the bed, her fingers curling deeper as she watched Rika writhe.
Rika's back arched off the bed, a cry tearing from her lips as her walls tightened instinctively around him.
"God… Rika," he groaned, his hips meeting hers in a rhythm that deepened with each thrust.
She clung to him, nails digging into his back, legs wrapping around his waist. Her body welcomed him eagerly, clenching and fluttering with each roll of his hips, each whispered word of praise into her ear.
"One…" he murmured.
She didn't understand at first.
Then another wave hit her—sharp and fast—and she cried out again, her first climax ripping through her like lightning. Her whole body tensed, and Shin didn't stop. He only smiled, his thrusts growing firmer, more deliberate.
Ai's fingers moved faster.
Rika came again.
"Two…"
Each time she reached that edge, he counted. Quietly, intimately, as though it were a secret only the two of them shared.
"Three…"
"Shin—please—" Rika sobbed, overwhelmed.
He kissed her again, deeper now, swallowing her cries, whispering promises against her lips.
"You can take it," he said gently, even as his hips punished her with relentless rhythm.
"Four…"
Her legs were trembling. Her voice had all but broken. Her body was on fire.
"Five…"
Ai was panting now, watching through glazed eyes, her other hand clutching her breast, twisting and teasing in rhythm with Shin's movements. Her thoughts were a mess—jealousy and arousal tangled so tightly that she couldn't tell where one ended and the other began.
"Six…"
Rika was sobbing in pleasure now, barely coherent, her skin burning, her hair clinging to her damp forehead. And still—he didn't stop. If anything, he grew more tender, more focused. His hands soothed even as his body pushed her past the brink.
"Seven…"
Every climax tore a new piece from her, yet left her more complete.
"Eight…"
Ai bit her lip hard, stifling a moan.
"Onii-San…" Rika whimpered, her voice cracking. "I—can't…"
He leaned down, their foreheads pressed together.
"Yes, you can," he whispered.
"Nine…"
Her body shook. Her lips trembled. Her hips lifted one more time, desperately meeting his.
And finally—finally—
"Ten."
Rika shattered, clinging to him like she might never let go again.
And that was when Shin allowed himself to let go.
His breath caught—his body stiffened—and he buried himself deep inside her, letting his climax crash through him like thunder.
They stayed like that, trembling together, hearts racing in sync.
Rika's eyes were glassy, her mouth parted in stunned silence. Shin gently stroked her cheek, brushing damp hair from her face.
"I'm still here," he whispered. "You did amazing."
Rika only nodded, too dazed to speak, but the faint smile on her lips said everything.
Ai, meanwhile, sat back, legs splayed, chest rising and falling rapidly. Her hands fell to her sides, her body flushed, her mind numb with satisfaction.
She stared at the ceiling, trying to understand what she felt.
Shin had just made love to Rika like she was the only girl in the world.
And Ai had watched every second.
Her best friend.
Her brother.
Together.
And yet… she hadn't looked away.
