Shin's eyes drifted across the bed, catching the soft rise and fall of Ai's chest as she slept, her body bare and inviting. A predatory grin spread across his face. Without hesitation, he moved over her, spreading her thighs apart, the scent of her arousal thick in the air.
Her lips parted in a soft, involuntary sigh as the blunt head of his cock pressed against her folds. She stirred slightly, but he didn't give her time to react. With one long, forceful thrust, he sank into her slick warmth, filling her completely.
"Ai…" he growled, voice low and commanding, gripping her hips tightly. "You're mine."
Her eyes snapped open, startled, breath hitching as she recognized him. "Onii-chan…!" she gasped, voice trembling, both from surprise and rising pleasure.
Shin didn't answer with words. His hands roamed over her chest, cupping her breasts, thumbs teasing her stiff nipples as he began a merciless rhythm. Each thrust drove him deeper, stretching her fully, pulling needy cries from her throat.
"Ohhh… Onii-chan… ahhh… so deep…!" Ai moaned, hands clutching the sheets, body arching beneath him.
He leaned down, lips brushing her neck, teeth grazing lightly as he continued his brutal pace. "You like that, Ai?" he murmured, squeezing her breasts, flicking her nipples with precise, torturous pressure. "You always take me so well."
Her back arched sharply, a strangled cry escaping her as her hips bucked, trying to meet his thrusts. "Ahhh… Onii-chan… harder… please!"
Shin obliged, slamming into her with ruthless force, hips snapping forward, filling her completely. Her moans became frantic, each one punctuated by the wet slap of their bodies meeting. His fingers dug into her flesh, kneading, pinching, teasing, sending shivers through her torso.
Her body trembled uncontrollably as he continued, each thrust driving her closer to the edge. "Ahhh… Onii-chan… I… I can't…!" she cried, voice cracking, hands clawing at the sheets.
"That's right," Shin growled, gripping her hips with unyielding strength. "Let it all out. Feel me inside you. All of me."
Her walls clenched violently around him, squeezing and milking him with every desperate gasp. His mouth found her nipple again, sucking and biting lightly, while his hands kneaded the other, making her scream in a mixture of pain and pleasure.
"Ohhh… Onii-chan! I… I'm… ahhh—!" Ai's voice broke as her first orgasm hit, waves of trembling pleasure washing over her. Shin didn't relent, riding her through it, driving deep, relentless, his own need building with each spasm of her body.
Her second orgasm hit before she could catch her breath, her entire body shaking as he continued pounding into her, fingers tightening on her hips, thumb circling her clit with precise, torturous rhythm. Each movement brought her closer to the brink again, her moans and cries filling the room, mingling with the wet sounds of their bodies.
Shin's grunts of exertion grew louder as he leaned over her, capturing her nipple between his teeth, biting gently before sucking, making her arch violently. "Mine," he hissed, voice low and guttural. "Only mine, Ai."
She gasped, body trembling, voice high and desperate. "Onii-chan… yes… yes! Please don't stop…!"
The combination of his relentless thrusts, nipple biting, and clit stimulation drove her over and over the edge, shuddering violently under him. Her walls contracted with every pulse, milking him as he rode her, each spasm of pleasure echoing through the room.
Finally, with a guttural growl, Shin's own climax hit, filling her completely, hot ropes of release spilling inside her. Her body convulsed beneath him, trembling, shivering, moaning helplessly as he rode out his own release, still pounding deep, still demanding, still claiming her fully.
They collapsed together, her body slick and shaking against his, breasts pressed into his chest, hair tangled, faces flushed and damp with sweat. Ai clutched him, whispering his name softly, exhausted but completely satisfied.
Shin smirked against her skin, pulling back slightly, letting her rest while his own body still pulsed with need. "Ai," he murmured, voice low and rough. "You took me so well."
Her lips curved in a tired, breathless smile. "Onii-chan… you… you're relentless…"
He chuckled darkly, fingers trailing over her damp skin, teasing, savoring. "And you love it, don't you?"
Her soft moans were the only answer, and Shin knew the night wasn't over yet.
