The weekend brought rare respite—no school, no shift. Kaito slept late, body demanding recovery from weeks of dual fronts.
He woke to sunlight filtering through curtains and the faint scent of breakfast wafting upstairs. Voices murmured below—female, warm, overlapping.
Downstairs, the kitchen glowed with morning light. Sayuri stood at the stove in a light sundress similar to last night's, but pale yellow today, thin straps crossing delicate shoulders, fabric clinging softly to her curves as she moved. Her hair was loose, wavy from sleep, brushing the small of her back.
Akari lounged at the table in tiny sleep shorts and a loose tank that gaped at the sides, revealing glimpses of sideboob when she reached for coffee. Legs stretched long, toned from runs.
Yui sat cross-legged on a stool, in an oversized pastel hoodie that slipped off one shoulder and soft cotton shorts riding high on her thighs. Silver twin tails messy, eyes bright as she helped set plates.
All three turned when he entered, smiles blooming.
"Morning, sleepy hero," Akari teased.
Sayuri's gaze lingered on him—knowing, warm from their shared night. "Breakfast is almost ready."
Yui bounced over for a hug, small body pressing close. "You deserve rest, onii-chan! After saving Sora-chan and everything…"
The embrace lingered—her cheek against his chest, arms tight around his waist. Innocent, but the softness of her through thin fabric stirred him.
He patted her head. "Minor deeds."
They ate together—pancakes, fruit, laughter. Touches casual but charged: Sayuri's foot brushing his under the table, Akari's elbow nudge, Yui feeding him a strawberry with shy fingers.
Afternoon: chores and relaxation. Kaito helped Sayuri with laundry—bending close in the narrow room, her scent enveloping, sundress riding up as she reached high shelves.
Akari dragged him for a quick jog—sports bra and shorts hugging her athletic form, sweat glistening by end. She punched his arm playfully. "Keeping up okay, weakling?"
Evening: family movie on the couch. Lights dim, blanket shared.
Yui nestled against his side, head on his shoulder. Hoodie zipped low, revealing delicate collarbones. Her hand rested on his thigh—innocent at first.
Sayuri on his other side, robe over dress now, leg pressed warm.
Akari opposite, feet in his lap eventually—"Massage, servant."
Tension simmered. Stolen glances. Lingering touches.
Movie ended late. Akari yawned first. "Bed. College tomorrow."
Sayuri kissed his cheek goodnight—lips soft, lingering. "Sleep well, sweetheart."
Yui hesitated at stairs. "Onii-chan… can I talk to you? In my room?"
He followed.
Yui's room: otaku paradise—posters of anime girls, plushies piled, soft pink lighting from fairy lights.
She closed the door softly, fidgeting in hoodie and shorts. "About the fight… and Sora-chan starting work… you're doing so much for everyone."
Kaito sat on her bed edge. "It is my role."
Yui climbed beside him, closer than necessary. Thighs touching. "I… feel left out sometimes. Mom and Aki-nee are older, stronger. I'm just… me."
Her blue eyes searched his—vulnerable, shimmering.
He cupped her cheek gently. "You are precious. Irreplaceable."
She leaned in, breath warm. "Really?"
The kiss began shy—her lips trembling against his, soft as petals. Kaito deepened slowly, hand sliding to her waist, pulling her closer.
Yui melted, small sounds escaping. Hands tentative on his chest.
Tension built like a gathering storm—slow, electric.
He trailed kisses down her neck, feeling her pulse race. Hoodie unzipped inch by inch, revealing smooth pale skin, small breasts in simple white bra—nipples already peaked against fabric.
"O-onii-chan…" she whispered, voice breathy.
He lavished attention—lips on collarbone, hands cupping breasts through bra, thumbs circling nipples until she arched, gasping. Bra unclasped, falling away. Breasts perfect handfuls—pert, pink-tipped, trembling with each breath.
Kaito worshiped them slowly—tongue swirling one nipple, sucking gently while fingers teased the other. Yui's fingers threaded his hair, moans soft and needy.
Lower—kissing down her stomach, hands sliding shorts off. Panties simple cotton, damp already. He peeled them slowly, revealing her—smooth, glistening folds, virgin pink.
Yui flushed crimson, thighs pressing together shyly.
"So beautiful," he murmured, parting them gently.
First touch—fingers tracing outer lips, feeling her slick heat. She whimpered, hips bucking.
He explored languidly—circling clit, dipping shallow inside, curling to find sensitive spots. Yui writhed, breaths coming faster, small hands clutching sheets.
When she neared peak—body tensing—he replaced fingers with mouth. Tongue flat against clit, lapping slow then faster, sucking gently. Two fingers eased inside, stretching carefully.
Yui shattered—back arching, cry muffled into pillow, walls fluttering around him, juices coating his tongue.
He let her ride it out, kissing inner thighs tenderly.
Then positioned above—clothes shed, his arousal hard against her thigh.
"Ready?" he whispered.
She nodded, eyes wide, trusting. "Please… be gentle."
He entered slowly—inch by inch, pausing at resistance. Kissed away her tears, whispering praise. "So tight… perfect for me…"
Full breach—gentle thrust past barrier. Yui gasped, clinging.
He stilled, letting her adjust—kissing deeply, hands stroking hair, back, breasts.
Movement began slow—shallow thrusts, grinding clit. Building rhythm as pain faded to pleasure.
Yui's legs wrapped him, heels digging. Moans grew louder, hips rising to meet.
Faster now—deeper strokes, her small body rocking beneath. Sweat-slick skin slapping softly.
Second climax built—her nails digging his back, whispers of "Onii-chan… love you…"
She came hard—walls clenching rhythmically, milking him.
Kaito followed—thrusts erratic, spilling deep inside with groan, pulses filling her.
Afterglow: tangled, breathing heavy. He held her close, kissing forehead.
"My precious one," he murmured.
Yui nuzzled, sleepy smile. "Yours… always."
Door cracked open suddenly.
Sora—visiting for study session, forgotten in passion—stood frozen, eyes wide behind glasses.
Face scarlet, she stammered, "I-I'm sorry! I heard noises and…"
Yui squeaked, pulling blanket.
Kaito met Sora's gaze calmly—though internally cursing timing.
Sora fled downstairs.
Yui buried face in his chest. "Oh no…"
He stroked her hair. "A complication. But… perhaps not unwelcome."
Tension lingered—new possibilities blooming.
