Shin collapsed slowly onto the bed beside her, pulling Ai into his arms with careful tenderness. Their bodies glistened with sweat, skin flushed and sticky, hearts still pounding in unsteady rhythm. Ai curled instinctively against him, burying her face into the crook of his neck as if trying to hide from the world—or from the remnants of the pleasure still echoing through her body.
Her entire frame trembled, her breath shallow. Her thighs twitched occasionally, her stomach rising and falling against his with each soft inhale.
"Onii-chan…" she mumbled, voice husky, barely audible. "It… burns…"
"I know," he murmured, brushing a hand down her spine, fingers featherlight. "You did so well, Ai. I'm proud of you."
His voice was warm, steady, anchoring her in the storm of overstimulation and lingering heat. She whimpered softly, nuzzling closer to his chest, where she could feel the slow thump of his heart. Its rhythm soothed her.
Shin glanced down at her body—swollen, flushed, marked with love. His own cock had finally softened, now a deep red and tender from the intensity of their movements. A part of him throbbed with guilt at how far they'd pushed each other.
He kissed the top of her head, his hand still stroking her hair. "Too much?"
Ai nodded faintly, her lower lip caught between her teeth. "You're a mean bull…"
Shin chuckled. "Bull?"
She pouted against his neck. "A big, stubborn, relentless bull. You didn't stop even when I was crying…"
"You were crying because you were happy," he countered with a smirk. "Your legs said yes. Your voice said yes. And your eyes… well, they rolled back, so I took that as a yes too."
Ai groaned in protest and swatted his chest weakly, but her fingers had no strength. "Don't tease… I'm completely ruined…"
Her thighs clenched around nothing, and she hissed at the soreness that bloomed there.
"You're not ruined," Shin whispered, lowering a hand to gently rub soothing circles over her lower back and hips. "Just full. And very, very well-loved."
She blushed furiously and hid her face even deeper against him.
"I can't walk," she muttered.
"You don't have to," he replied, smirking. "I'll carry you. Princess-style. Or maybe over my shoulder like a sack of rice."
"Stop!" she whined, laughing despite herself.
He shifted a little, eyes drifting downward again. "Mmm… Your little hole is still twitching…"
"Shin!" Ai squeaked, glaring up at him.
He grinned, utterly unrepentant. "What? It's cute. Like it's pouting that I'm not inside anymore."
Ai made an outraged sound. "Y-you're not even hard anymore!"
He shrugged playfully. "So? I've got fingers. And a tongue."
She stiffened immediately, eyes wide. "Don't you dare."
He leaned in closer, lips grazing her ear. "Just a little taste…"
"No!" she gasped, squirming and trying to wiggle away, only to groan at the soreness between her legs. "I'll die."
Shin laughed, his breath warm against her cheek. "Fine, fine. I'm kidding."
"You're not funny," she pouted.
"You're cute when you're scared of me," he teased, pulling her close again and wrapping both arms tightly around her.
"I'm not scared. I'm exhausted," she mumbled, eyes fluttering closed.
He kissed her forehead softly. "Then sleep, Ai. I've got you."
Her arms came around him slowly, fingers curling against his back. The burn in her body dulled beneath the warmth of his embrace. Despite the soreness, the faint sting, she felt… whole. Safe. Cherished.
Their lips met in a lazy, lingering kiss. Not desperate. Not hungry. Just warm. Familiar. Home.
"I love you," she whispered, the words tumbling out like breath.
"I love you more," he replied easily, resting his forehead against hers.
The room was quiet now. Just the hum of the evening outside the window, the faint rustle of sheets as their bodies shifted slightly to find the perfect fit.
Ai's breathing evened out slowly, her eyelashes brushing his skin. Her legs tangled with his beneath the covers, and her fingers loosened their grip as sleep took hold.
Shin remained awake for a moment longer, gazing at her peaceful face, brushing away a few stray strands of hair.
"My greedy little sister," he whispered, his heart impossibly full. "You want the whole world from me."
He smiled, placing one last kiss on her lips.
"And I'll give it to you."
Then he closed his eyes, letting the warmth of their shared breath lull him into sleep beside her.

The morning sun filtered softly through the curtains, casting golden rays over the bed where two tangled forms lay. Ai stirred first.
Her eyelashes fluttered, and a sleepy yawn escaped her lips. For a moment, she just breathed—long, deep, content sighs. Her body ached. Every inch of her, especially between her thighs, pulsed with the faint soreness of the night before. Yet as the memories returned—each intense moment, every gasp and cry, the impossible positions, and the way her Onii-chan held her afterward—her heart swelled with warmth.
A slow smile tugged at the corners of her lips.
He really made love to me.
She bit her lower lip, cheeks turning a vibrant red as she recalled how he took her, how she begged, how he didn't stop even when she said she couldn't anymore. The real sex, her first time taken so deeply... even the embarrassing anal position that had made her cry out in ways she didn't know she could.
And yet, she was happy. Incredibly happy. She turned her head slightly to look at him. Shin's chest rose and fell slowly, his arms still loosely around her, his expression soft and peaceful in sleep.
Ai leaned forward and pressed a gentle, lingering kiss to his lips.
"Onii-chan..." she whispered against his mouth.
He didn't stir.
Smiling fondly, she very slowly began to slip out of bed, careful not to wake him. As soon as her feet touched the ground, a sharp sting radiated up her thighs. She hissed, holding onto the edge of the bed.
"I really might not be able to walk today," she muttered, chuckling under her breath.
But even with the soreness, she stood. Because she knew her Onii-chan had school today. And if he had to go, then she wanted to make sure he had a warm breakfast to remember her by.
She grabbed her nightgown from the floor, wincing as she bent down to pick it up, then shuffled slowly toward the bathroom. There, she brushed her teeth, washed her face, and ran cool water down her arms to freshen up. Despite the ache, she felt invigorated. Loved. Claimed.
In the kitchen, the aroma of rice and miso soup soon began to fill the air. Ai hummed softly to herself, occasionally touching her lips and blushing at memories. She moved gingerly, but she moved. For him.
From the bedroom, the sound of shifting sheets and a sleepy voice drifted into the hallway.
"Ai...?"
She smiled to herself.
"Morning, Onii-chan!" she called sweetly.
There was a pause, then Shin's voice replied, more awake now. "Morning... what time is it?"
"Still early. We went to sleep pretty fast yesterday, remember?"
Shin groaned lightly as he sat up, stretching his arms with a yawn. "Yeah... guess we were wiped out."
He rubbed his face and stood, feeling unusually refreshed. The events of the previous night were still vivid in his mind. He smiled to himself as he headed for the bathroom. After a quick brush and a cold shower, he dried his hair with a towel, glancing at himself in the mirror.
His reflection showed a tall, lean young man with tired but bright eyes, hair slightly tousled but clean. As he buttoned his high school uniform, pulling the collar straight and adjusting his tie, he looked every bit the proper student. Except, perhaps, for the faint red marks that lingered on his neck.
He smirked. Ai's love had left its mark on him.
He padded quietly into the living room, guided by the delicious smell wafting from the kitchen. Ai stood at the stove, gently stirring a pan, her hair tied up in a lazy ponytail. She wore his oversized shirt again, the hem barely covering her thighs.
Without a word, Shin stepped behind her and wrapped his arms around her waist.
Ai jumped slightly. "Onii-chan! You scared me!"
He kissed the side of her neck. "Good morning, chef."
"You didn't make a sound..."
"That was the plan."
He kissed her again, lower this time, just above her collarbone. She let out a little giggle.
"What are you making?"
"Rice, grilled salmon, tamagoyaki, and miso soup," she replied proudly.
Shin grinned. "My favorite. You're spoiling me."
She blushed, trying to hide her smile. "You deserve it. After... last night."
He tightened his arms slightly around her. "You were amazing last night, Ai. All of you."
Her face glowed. "Don't tease me while I'm cooking..."
"I'm complimenting you," he said innocently.
Ai rolled her eyes and leaned back into his chest. "Eat first. Tease later."
He chuckled and nodded, still hugging her for a few more moments before finally letting go to set the table.
The quiet morning continued, wrapped in warm silence and the gentle clatter of bowls and chopsticks. For both of them, this moment felt like peace.
And love.
And home.
