Sakura quickly moves away from Lux's reach.

She glares at him with an intense look.

Sakura cracks her knuckles, signaling her readiness for battle. The tension in the air rises as she assumes a combat stance, staring at Lux without breaking eye contact.

Her brows furrow in annoyance at his playful refusal to stop calling her 'sis'.

Her voice remains level, but determination hardens her gaze.

With swift steps, she closes the distance between them.

Without hesitation, she launches a blistering fast straight punch right at Lux's jaw, her striking speed and force immediately showcased in her opening gambit. The whole arena watches with bated breath, eager to see if this little sister is just hype or the real deal.

Sakura uses her lead fist to redirect Lux's kick, the motion fluid and natural like a dance.

She swiftly responds, not just defending but immediately countering with an elbow to Lux's side.

Sakura's strikes are rapid and continuous, striking while he's off-balance, not allowing him time to set up his heavy hitters.

Her punches land sharp and fast, each carrying deceptive power behind them.

Her rhythm doesn't falter, moving from open-hand strikes to quick jabs to a spinning back kick, each hit perfectly calibrated to test Lux's ability to adapt.

The bitterness in her voice is palpable as she presses her assault, a barrage of lightning-fast kicks keeping Lux firmly on the defensive.

Sakura feints low, using the motion to slip a blindingly fast jab into Lux's guard, aiming squarely at his chin.

Even as she pushes her advantage, Sakura's gaze remains cold, any hint of her old affection for Lux long since buried.

Sakura comments. She leaps back, maintaining a wary distance between her and Lux.

Her expression remains stoic, showing little emotion other than cold focus.

Sakura's eyes narrow as she studies her brother. She seems calm on the outside, but her inner turmoil and determination are undeniable. She circles Lux, probing for an opening to unleash the full might of her speed and technique once more. She darts in with another lightning fast combo, using fast hits to probe Lux's defenses, looking for that elusive opening that will allow her to launch a decisive strike.

Sakura sees the determined look in Lux's eyes, a spark of her old affection for him almost resurfacing briefly.

Sakura ducks under one of Lux's swings, immediately turning it into a counter attack, hitting Lux hard across the ribs.

Sakura's eyes flash with a bitter laugh.

Sakura doesn't go for the kill, she continues pressuring him, wearing him down with her relentless barrage of attacks. It's not just about winning anymore. For Sakura, this is personal. She wants Lux to realize, to understand just how much his constant comparisons and neglect hurt her.

Sakura grins coldly.

She releases her hold, allowing Lux to stumble back. But she doesn't pursue, waiting to see how he responds to her ruthless assault.

She maintains her distance, baiting Lux to try and test if his defenses are still solid.

Sakura's hands curl into fists, ready for the next exchange, but also watching, calculating. She knows this battle is far from over, that Lux still has some fight left in him. But for now, she has the advantage.

Sakura quickly parries and dodges Lux's onslaught, her speed and agility still on point. She slides under one of his high kicks, using it as an opening to lash out with her own attacks.

She taunts, her relentless combos keeping him on the defensive. Ducking another incoming fist, Sakura launches an uppercut that connects solidly with Lux's chin.

Sakura follows up with a flurry of jabs that land unerringly against Lux's guard.

Sakura ends with a powerful roundhouse kick, the sheer force of it enough to send Lux staggering backwards, barely managing to stay on his feet. As she lands, Sakura readies herself for another attack, her relentless assault far from over.

She laughs coldly, not letting up for a moment. Her punches land like a relentless rain.

Sakura keeps hitting, targeting Lux's limbs to limit his movements, her attacks measured but deadly, aimed to cripple rather than maim.

Sakura muses as she lands another sharp punch to Lux's ribcage.

With a vicious grin, Sakura unleashes a flurry of kicks, each one striking with practiced accuracy, painting Lux's skin with shades of purple and red.

Sakura spoke calmly, not showing any exhaustion in her voice.

Her hands gripped tight around Lux's neck, cutting off his air supply.

A wicked smirk graced her face.

She whispered darkly into his ear, her grip tightening like a noose.

Sakura kept staring intensely at her brother as he struggled to breathe.

Sakura let out a chuckle, amusement in her eyes.

Sakura leered as she drew back her leg, ready to unleash the devastating knee.

The gleam of victory and vicious satisfaction shone in Sakura's eyes.

She focused on her target, savoring the impending moment of triumph.

Sakura whispered mockingly, just a fraction of a second before she thrust her knee forward.

Her knee dug deeper into his most sensitive area, rubbing and grinding brutally against it. Lux winces and groans loudly. Sakura shows no mercy, enjoying his humiliation.

She chuckles, the cruelty etched into her face.

She spits the words out like venom, punctuated by more grinding and rubbing that keeps Lux in constant agony.

Lust begins to take over her eyes, aroused by Lux's misery.

She enjoys every gasp of pain, her breath hot on Lux's skin as she invades his personal space. Her tongue glides along his cheek, leaving a wet trail that disgusts and humiliates him further. Her leg works double-time, the shaking rhythm painful enough to make Lux's body convulse with each impact.

She whispers, taunting him with his own powerlessness. A crazed look takes over her face as she forces him to endure her wrath.

Sakura intensifies her assault, savoring the raw pleasure of dominating her brother. In that moment, Sakura finds the sick satisfaction she yearned for all those years of repression. This is her power. His helplessness. Her sadistic bliss.

Sakura smiled gleefully as she watched Lux's orgasm. With a mischievous grin, she slowly removed her knees from his crotch.

Sakura mockingly commented as Lux's body slumped to the ground.

She reached out her arms, wrapping them tightly around Lux's waist in a bear hug before he could hit the floor.

She squeezed with brutal force, eliciting pained moans and screams of agony from Lux.

With a sickening grin, Sakura continued her relentless assault.

Sakura mused as she delighted in the sound of Lux's excruciating cries.
