The morning after Yui's awakening dawned awkward.
Kaito descended to the kitchen, body pleasantly sore from the night's tenderness. Sayuri was at the stove in a soft robe over lingerie—silk clinging to her curves, hair tousled from sleep. She glanced up, cheeks flushing at his gaze, a secret smile playing on her lips.
Yui followed soon after, in fresh pajamas: a cute oversized shirt with a chibi character and tiny shorts that barely covered her thighs. She avoided eye contact at first, blushing fiercely, but when their eyes met, she beamed shyly and hugged him from behind at the table.
"O-onii-chan… morning," she whispered, cheek pressed to his back.
Sayuri's smile deepened, maternal and knowing.
Akari entered last, fresh from a shower—damp hair in a messy bun, wearing a tight sports bra that hugged her firm breasts and low-rise shorts that rode high on her athletic hips. She paused in the doorway, green eyes narrowing as she took in the scene: Yui's clingy hug, Sayuri's soft gaze, Kaito's relaxed posture.
The air shifted—thick, charged.
Akari grabbed coffee roughly. "What's with the lovey-dovey atmosphere? You all win the lottery or something?"
Yui squeaked, releasing Kaito. Sayuri busied herself with plates.
Kaito met Akari's stare calmly. "Merely a pleasant morning."
Akari's jaw tightened. She sat opposite, legs crossed, foot bouncing. Throughout breakfast, her glances sharpened—watching Yui's lingering touches, Sayuri's subtle brushes against him.
School and work passed in a haze.
At school, Haruka teased about weekend plans. Sora, bolder now from her shifts, sat closer at lunch, offering snacks with shy gratitude.
Work: Reina's dramatics, Haruka's competition, Sora's fumbling cuteness. But Kaito's mind lingered home.
He arrived late evening. House quiet—Sayuri at a rare overtime, Yui at a friend's study group (Sora's, ironically).
Akari waited in the living room, in yoga pants that clung like second skin and a cropped hoodie zipped low, revealing sports bra and toned midriff. She scrolled her phone, but looked up sharply when he entered.
"Finally," she snapped. "Sit. We need to talk."
Kaito obeyed, sensing the storm.
Akari tossed her phone aside, standing to pace. "What the hell's going on? Mom's glowing like a teenager. Yui's practically glued to you. And you—strutting around like you own the place more than usual."
He lifted his chin. "I provide. Protect. It strengthens bonds."
She stopped, hands on hips, eyes flashing. "Bonds? Don't bullshit me. I see how they look at you. How you look at them." Voice cracked slightly. "Am I the only one left out?"
Jealousy—raw, tsundere fire.
Kaito rose slowly. "You are not excluded. You are… essential."
Akari laughed bitterly. "Essential? You barely touch me anymore. Not like—" She cut off, cheeks reddening.
Tension crackled.
He stepped closer. "Like what?"
She shoved his chest—half angry, half desperate. "Like you're touching them! I'm not blind, Kaito. Or stupid."
He caught her wrists gently, minor strength holding firm. "Then see this: I want you. Always."
Akari stilled, breathing hard. Eyes searched his—anger melting to need.
The kiss exploded—her initiating, fierce, teeth nipping his lip. Hands fisting his shirt.
Kaito responded with centuries of restrained hunger—backing her against the wall, deepening the kiss until she moaned into his mouth.
Clothes peeled urgently.
Hoodie unzipped, sports bra pushed up—revealing perfect breasts, larger than Yui's, nipples dark and hardened. He lavished them roughly at first—sucking hard, teeth grazing until she gasped—then softer, tongue swirling.
Akari's hands yanked his shirt off, nails raking his back. "More… damn it…"
He spun her, pressing her front to the wall—yoga pants peeled down slowly, revealing firm ass and soaked panties. Panties tugged aside.
Fingers first—tracing her slick folds, circling clit until hips bucked. Two fingers plunged deep, curling, pumping rhythmically. She was tighter than expected, walls clenching greedily.
"Fuck… Kaito…" she whimpered, tsundere facade shattering.
He withdrew, spanking one cheek firmly—sharp crack echoing. She yelped, then moaned deeper.
"Like that?" he growled.
Another spank—harder. Red bloom on skin. "Yes… punish me… I've been jealous… bitchy…"
More spanks—alternating cheeks, building heat. Between, fingers teased her entrance, denying full penetration.
Akari trembled, legs spreading wider. "Please…"
He used his tie—silk binding wrists behind her back. Light bondage, but enough to make her arch.
Positioned behind—cock hard, sliding along her slickness, teasing clit.
Entered slow at first—thick head stretching her. She gasped, pushing back impatiently.
Deeper thrusts—building to pounding rhythm. Bound hands helpless, body rocking against wall.
Spanks punctuated thrusts—each making her clench tighter.
Sweat slicked skin. Her moans louder, needy. "Harder… own me…"
He obliged—grip on hips bruising, pace relentless. One hand reached around, rubbing clit in circles.
First orgasm crashed—body seizing, walls milking him rhythmically, cry echoing.
He didn't stop—thrusting through, prolonging.
Untied wrists—spun her to face him, lifting against wall. Legs wrapped his waist.
Re-entered deep—face to face now. Kissing fiercely as he bounced her on his length.
Second build—her nails digging shoulders, eyes locked. "I… love you… idiot… don't leave me out…"
Confession broke her—orgasm shattering again, tears spilling.
Kaito followed—thrusts erratic, spilling hot inside with groan, filling her completely.
Afterglow: lowered gently to couch, bodies tangled. He stroked her hair, kissing tears.
"You are mine," he murmured. "All of you. No exclusion."
Akari nuzzled his neck, voice small. "I… don't want to share. But… if it's them… I'll try."
Emotional reconciliation—jealousy sated, deeper bond forged.
Later, cleaned up before others returned.
But the court expanded—tsundere flame now devoted blaze.
