Awakening: My Yandere sister is obsessed with me

Haruto knocked on Akiko's door, heart heavy. When she opened it, she pulled him into a warm embrace.

"Oh, I knew you'd come find me," she teased, her playful smile easing his guilt. Her arms felt like home, and for the first time in days, he breathed easy. The door closed softly behind them.

Haruto's hands gently cupped Akiko's face, his gaze an intense, searching question. Akiko's eyes fluttered shut, unable to meet the burning intensity of his stare, and in that fragile moment, Haruto leaned in, his lips finding hers with a tender urgency.

A wave of searing warmth enveloped Akiko as their mouths met, a soft, involuntary moan escaping her lips as her legs threatened to buckle beneath her.

Haruto pulled her closer still, deepening the kiss into a consuming inferno. She felt herself dissolve into the sensation, utterly lost in the embrace. His tongue, a playful serpent, expertly parted her lips and teeth, teasing hers with an exquisite dance.

Akiko's full breasts pressed intimately against Haruto's chest, rising and falling with each rapid, breathless intake.

She responded instinctively, her own tongue eagerly meeting his, savoring the intoxicating, new taste of their intertwined desire.

They held each other in a passionate embrace, a world unto themselves where the very fabric of time seemed to unravel and cease to exist. Without a conscious thought, Akiko's arms had wound around Haruto's neck, while his hands, with a feather-light touch, began to trace the delicate curve of her back.

Finally, with a shared, lingering breathlessness, they parted. Haruto's fingertips gently grazed Akiko's cheek, his voice a low, husky whisper, "Akiko, shall we go to your room?"

Her eyes, still hazy with unspoken emotions, gave a silent nod. With that, Haruto led her, a magnetic pull drawing them together, back to her room. The door clicked softly shut behind them, sealing them within their private sanctuary, where they were once again enveloped in a fervent, all-consuming embrace.

Within the soft lamplight of her room, Akiko found herself laid bare, her body glistening with a captivating allure, her legs now spread in eager invitation.

Haruto, once more consumed by an insatiable desire, gently rolled her onto her back, his hands tracing the exquisite curves of her firm, round buttocks, kneading them with a fervent intensity. Unable to resist the damp, beckoning depths between her thighs, his fingers slipped inside, exploring her with a knowing touch.

He positioned himself above her, then plunged downward, a powerful, deliberate thrust that sent a tremor through Akiko's entire being. A cry of pure bliss, of profound and utterly consuming satisfaction, escaped her lips, urging him on.

"Harder, harder, my love," she pleaded, her voice a husky, breathless whisper, lost in the crescendo of their shared passion.

He began to caress Akiko's breasts, his voice a low murmur of praise.

"Akiko, your breasts are wonderful, so wonderfully large and soft, and truly, incredibly elastic..."

A flush of pride bloomed across Akiko's cheeks, a natural response to his tender admiration. She reveled in his touch, her smile growing more alluring, more open.

"Really? You're caressing me... it feels so good... and you're touching me there... it feels so good..."

Haruto peeled away her T-shirt, unfastened her bra, and then lowered his head, his mouth closing over one of her waiting nipples.

Akiko was utterly enthralled, her waist and hips beginning to rock intensely, her body flowing, yielding, even more.

"Oh, darling... keep sucking... use more force... ah... ah... it feels so good..." He continued to suckle, drawing her into a deeper realm of sensation, before finally releasing her, only to compliment her again.

"Don't stop... lick me more... yes... it feels so good...oh... it's so good... But that woman... Satsuki... her breasts are even bigger... even fuller..."

"Don't talk about her, only you and I here." He thrust deeply a couple of times, his voice thick with arousal.

"Ah... ah... deeper..." Akiko gasped, her voice trembling, "They are... big... and firm... once... when she and I were in the room... changing clothes... I saw her breasts... oh, it felt so good... just seeing how big they were... I reached out to touch them... so elastic... so plump... I deliberately... ah... deeper, deeper... ah... I guessed... her nipples were so perfect and pink... stood erect and quivered on you... I was so jealous when I saw them..."

"Don't talk about her..." he urged, his voice a low growl. He was listening intently, his own excitement swelling, making Akiko's movements even more beautiful.

Akiko thrust down, again and again, urging him deeper, seeking to reach the very bottom of their shared ecstasy.

Late, she was so weak, collapsing on the bed. instinctively reached out... and touched her lower abdomen... sparsely haired. She was already flowing with wetness onto his hand... and kept moaning. "Such a lustful girl... I only... touched her for a while... and she just... oh... oh... it felt good... she completely soaked the bed..." He thought.

Upon hearing this, he could no longer restrain himself, and with a fervent "thump-thump," he reached his climax, his body shuddering with release.

"Ah... darling... so hot... I'm... coming too..." Akiko seized the moment, before he could soften, her hips rocking violently, extracting his last remnants of energy. Suddenly, her heart fluttered, and she too released, a gush of pleasure, further soaking his pants.

He embraced Akiko with a profound satisfaction. Akiko lay softly on his chest, her breath coming in short, rapid pants.

"You're so naughty... hearing me talk about other girls makes you... this excited... and finish so quickly..."

He gently caressed her buttocks, his voice a playful murmur, "No..."

Akiko feigned protest, spitting playfully, "You wish... make me feel good one more time, and I'll consider it..."

Hearing Akiko's playful suggestion, he instinctively grew harder again. Without a moment's hesitation, he flipped her over, pinning her to the seat, and without letting her catch her breath, he began to thrust wildly and fiercely. Akiko was drenched in passion, her small, rounded hips moving in perfect rhythm with his movements, both of them completely lost in the fervent intimacy of their shared desire.

Akiko lay on her back, legs spread, her entire body wet, lustful and beautiful. Haruto, once again consumed by desire, rolled her over, his hands kneading her firm, round buttocks.

He then slipped his fingers into the damp depths between her thighs, positioning himself over her, thrusting down hard, so powerfully that Akiko's entire body trembled. She let out a cry of pure bliss and profound satisfaction, urging him on.

"Harder, harder, my love..." she pleaded, her voice a husky whisper...

Exhausted after pushing herself to the limit, Akiko lay panting, her strength utterly drained. Haruto hesitated for a long moment before gently brushing his fingers against her flushed cheek. His voice was quiet, deliberate. "I... have to leave this place."

Akiko's eyes flew open. Her fingers immediately tightened around his wrist, nails digging in as if she could physically chain him to her side. "What... do you mean?" she whispered, voice trembling.

"I'm going abroad. To study," Haruto lied, avoiding her gaze.

"Liar!" Tears welled up instantly, her lips quivering. "It's her, isn't it? That woman won't let us—"

He cut her off with a kiss—soft but firm. "No. This is my choice."

Akiko shattered. Sobs wracked her body as she screamed curses, her fists pounding wildly against his chest. When words failed, she clawed at him, desperate to leave marks he couldn't ignore. Haruto said nothing. Instead, he pulled her into his arms, burying his face in the damp warmth of her chest. Her heartbeat was frantic against his ear.

"I do love you," he murmured, the truth slipping out like a confession. "That's why... I have to go."
