*****
Sunday morning arrived in a hush of gold.
Rito drifted awake to the slow spill of sunlight across the tatami, the quiet so complete it pressed against his eardrums like water. No warm tangle of limbs. No soft tail curled possessively around his waist. No muffled giggles in the dark.
The futon felt cavernous.
Memory flooded back in a visceral rush, striking him long before his eyes fully adjusted to the morning light. A shiver traced its way down his spine, a phantom sensation returning to his nervous system.
He remembered the blindfold.
He remembered the silky, vibrating alien gloves.
He remembered the hands—small, eager, merciless in their exploration and control.
He lay there for a moment, letting the events of the previous day wash over him. It had been... a lot. A whirlwind of emotions, expected yet unexpected situations, and "interactions" that left his head spinning even now.
He thought of Lala's tail circling, teasing, stopping.
He thought of Sachie's mouth, hot and humming, swallowing his desperation.
He thought of Mami's tears, her cracked voice, her gaze full of worship.
He thought of his thick, and almost endless release that painted their faces in glistening white.
He thought of Mikan's door slamming like a gunshot. His own hoarse promise of pancakes.
His body remembered every second. His cock stirred beneath the sheet, already half-hard, the thick vein along the underside pulsing with phantom sensation. His new-forming flexed as he shifted, skin still tingling where Mami's tears had cooled.
Then he saw a note.
A single square of pink paper, stuck to his pillow in glitter ink:
"I researched ALL night! Meet me in my room after breakfast~!— Your future wife"
The words hit like a spark to dry tinder.
His heart slammed against his ribs, a frantic drumbeat that drowned out the quiet. His cock throbbed, fully hard now, the head pressing insistently against the sheet, a warm bead of pre-cum already soaking through. His palms went damp.
'She researched?'
'All night?'
'Where did she research?'
'The Earth's internet?'
'What did she find? What does she want today?'
'Will it again be like yesterday's one? Or… more?'
The phrase "your future wife" burned behind his eyelids. His breath came shallow. His fingers trembled as he peeled the note free. It fluttered to the floor like a fallen petal.
He stood on unsteady legs. The house was too still. From downstairs drifted the faint clink of a spatula on cast iron, the sweet scent of butter and vanilla curling up the stairs like an invitation.
'Mikan.'
He exhaled, steadying himself.
'Pancakes first. Then… whatever Lala had waiting.'
He had promised to make pancakes with her. That was the least he could do after everything.
…
Downstairs, the kitchen smelled like butter and vanilla. Mikan stood at the stove, flipping pancakes, humming a pop song off-key. Batter speckled her apron like abstract art. A bowl of batter sat beside her, half-empty. She didn't turn when Rito entered, but her shoulders relaxed.
She glanced over, flour dusting her nose. "Morning, slowpoke. Grab the syrup before Lala drinks it straight again."
She said, voice soft. "I started the batter. You promised, remember?"
Rito smiled, rolling up his sleeves. "I wouldn't dare break my promise with my dear little sister now, would I?"
They moved in perfect sync. He whisked eggs. She poured batter in neat circles. The sizzle of butter on the griddle filled the silence. He stole a blueberry from the bowl; she swatted his hand with the spatula, but her lips twitched.
"You're getting better," she said, watching him flip a pancake with one smooth motion. "And… stronger."
Mikan's eyes drifted to the way his T-shirt clung to his midsection when he stretched for the syrup bottle. The faint ridges of his abs pressed against the fabric like a secret she wasn't supposed to notice.
Rito caught the look, and his ears went reddened a bit.
He scratched the back of his neck, voice dropping to a flustered mumble.
"You're my sister, Mikan… if you're that curious about what's under the shirt, just say the word. I'll always oblige."
The spatula froze mid-flip.
Mikan's face exploded in crimson. "W-What are you saying, Baka Rito?!"
Rito laughed, soft and sheepish, though his ears were still burning from his own words, he believed that the tension would melt into the familiar rhythm of their mornings.
Meanwhile Mikan's face was a furnace, her eyes were fixed on the griddle like it held the secrets of the universe.
The spatula continuously trembled in her grip.
Silence stretched, thick and electric.
She didn't push.
She couldn't.
Her throat worked, but no sound came out.
Finally, she slid a perfect golden pancake onto a plate with a clink and nudged it toward him—harder than necessary. The plate scraped across the counter, stopping just short of his fingers.
They ate standing at the counter, shoulders brushing, the way they used to when they were kids. Only now the air crackled with something else.
Rito chewed mechanically. Mikan stabbed her pancake like it had some enmity with her.
Just then, the front door burst open.
"Morning~♡!"
Lala bounded in, tail swishing, followed by a sleepy Sachie and Mami rubbing their eyes. They piled into chairs at the dining table like it was the most natural thing in the world.
Mikan served without a word.
Pancakes stacked high.
Syrup.
Whipped cream.
Blueberries.
Sachie leaned over to Mikan, voice dripping with mischief. "Your onii-chan was so sweet last night. Chased you all the way to your room to make up~"
Mami nodded, cheeks pink. "And this morning… you guys… look extra close in the kitchen."
Mikan choked on her orange juice, spoon clattering against her plate. "I-It's not like that!"
Heat surged to her face in a single, unstoppable wave.
She folded her arms so tightly her knuckles paled, eyes flashing with a storm she couldn't name.
"We're just siblings." she said, the words small and brittle, like glass about to shatter. It was like she was trying to convince herself as much as them.
Lala's head cocked to one side, her tail tracing a slow, thoughtful arc through the air. "But siblings can be close~♡" she said, the words light as dandelion seeds, yet they landed like stones in still water.
Sachie's grin sharpened, all teeth and mischief. "Last day of our sleepover, Mikan-chan. We're heading back home after dinner. Let's make it unforgettable— how about a grocery run for a feast?"
Mami's hands came together in a soft clap, eyes bright. "I'll carry whatever you need!"
Mikan paused, fork hovering mid-air, then gave a curt nod. "Fine. But no taking Lala-san's inventions in the store."
"Roger!" *2
Soon after the breakfast, the three girls swept out in a whirlwind of laughter and swinging bags, the front door clicking shut behind them like the final note of a song.
…
"Sigh…"
Rito let out a slow breath, the sound swallowed by the sudden hush that settled over the house. The front door had barely clicked shut behind the girls when the silence pressed in, thick and expectant.
He climbed the stairs one by one, each step echoing like a heartbeat in the empty hallway.
The guest room door stood ajar, a sliver of warm light spilling across the floorboards. Inside, Lala waited by the window, her back to him, silhouette framed in the late-morning glow.
No bounce in her stance.
No tail flicking like a metronome of mischief.
Only stillness—an unfamiliar gravity that made his stomach twist.
She turned.
Her eyes caught his, and the usual sparkle was gone.
In its place burned something deeper, steadier.
"Rito."
He crossed the threshold.
The door closed behind him with a soft, final click.
"I stayed up all night," she said, voice low, almost reverent.
"Earth's internet… I searched about everything through it."
She drifted closer, feet barely brushing the tatami, hands clasped tight at her waist.
"I thought tail-docking was just play. A game of pleasure. A way to understand you."
Her lashes lowered, then lifted again.
"But it's not.
It's love.
It's giving you every part of me—body, heart, the rest of forever."
She reached for his hands. Her fingers trembled against his palms, but her gaze never wavered.
"I love you, Rito.
Not because of a beam.
Not because of duty.
I want to give you all of me.
Today.
Always."
His throat closed.
He curled his fingers around hers, grounding them both.
"Lala…"
His voice came out rough, scraped raw by truth.
"I've loved you since the moment you crashed through my roof and turned my world upside down.
At one time, I was scared. Scared of whether am I worthy of you or not? Whether I should just give up…
But I'm done running."
He drew her in until their foreheads touched, breath mingling.
"I want this.
I want you."
The room answered.
A low vwoom rippled through the air.
The floating bed hummed, rising an inch higher, but gravity stayed firm.
They remained grounded, feet on the tatami, breath mingling in the warm space between them.
Clothes slipped away in hurried, trembling hands—shirt over head, skirt pooling at feet, underwear kicked aside.
No drifting.
No weightless dance.
Just skin on skin, heat on heat, the bed waiting behind them like a promise.
…
The guest room door clicked shut behind them, sealing the world outside.
Lala's hands found the hem of Rito's shirt.
Her fingers trembled, but her eyes never left his.
She tugged it upward, slowly, reverently.
The fabric caught on his shoulders, then slipped free, pooling at his feet.
His newly forming 4-pack flexed under her gaze, skin warm and golden in the late-morning light.
Rito's breath hitched.
He reached for her, palms sliding under the thin straps of her top.
One tug, and it fell away.
Her breasts spilled free, soft and perfect, nipples already stiff.
He cupped them, thumbs brushing the peaks, drawing a sharp gasp from her lips.
Their mouths crashed together.
No gentle start.
No hesitation.
A hard-core kiss, teeth clashing, tongues tangling, breath stolen and shared.
Lala moaned into his mouth, a low, needy mmph that vibrated through his chest.
Her tail curled around his waist, pulling him flush against her.
His cock, already rock-hard, pressed against her stomach, leaving a warm, wet trail of pre-cum.
Rito's hands moved lower.
He hooked his fingers into the waistband of her shorts, dragging them down with her panties in one motion.
She stepped out of them, bare, glistening.
His fingers found her pussy—soaked, swollen, dripping.
He rubbed her clit in slow, firm circles, then slid two fingers inside.
Shluck-Shluck!
The wet sound of his fingers pumping filled the room. Lala's hips bucked, tail tightening around his waist.
"R-Rito… ahh…!"
She dropped to her knees.
Her first blowjob started innocent.
Lips parted, tongue tentative, licking the head like it was candy.
Then she took him in.
One inch.
Two.
Three.
Her throat opened, and she deep-throated him in one smooth, expert motion—two minutes from start to finish.
Gluck-Gluck-GLUCK-GLUCK!
Her cheeks hollowed, throat contracting around his shaft.
She hummed, the vibration shooting straight to his balls.
"Mmmmmm~♡"
Rito's hands tangled in her hair.
He held her head, guiding her rhythm, voice rough.
"Like that… deeper… yes… fuck…!"
She gagged once, glrk, but didn't stop.
Saliva dripped down her chin, pooling on the tatami.
Her tail curled around his thigh, squeezing in time with her bobs.
Rito pulled her up, spun her around, laid her on the floating bed.
The mattress dipped under their weight, still hovering an inch above the floor.
He returned the favor.
His mouth found her pussy—wet, sweet, pulsing.
He licked her clit in slow, firm strokes, then sucked.
Slurp-Slurp-SLURP!
Lala's back arched, tail thrashing.
"R-Rito… I'm—"
He rubbed the tip of her tail with his thumb, circling the heart-shaped end.
She orgasmed.
"AHHH—!"
A gush of clear fluid squirted across his face, warm and sticky.
They flipped into 69.
Lala on top, mouth back on his cock.
Rito below, tongue buried in her pussy.
Gluck-Gluck-GLUCK!
slurp-slurp-SLURP!
Mutual moans, wet sounds, the bed creaking under their rhythm.
Rito's hips bucked upward, chasing her throat.
He came first.
His voice cracked, raw and desperate.
"L-Lala… I'm— cumming—!"
A massive load flooded her mouth.
SPLURT-SPLURT-SPLURT-SPLURT!
Thick, hot ropes hit the back of her throat with wet thwacks.
She gulped frantically, throat working with soft glurk-glurk-glurk, swallowing every drop.
Her cheeks puffed, eyes watering, but she drank it all.
Rito didn't stop.
His teeth grazed her clit—gentle, then firm.
A sharp bite, and Lala's whole body seized.
"R-RITO—!"
Her scream muffled around his cock.
SQUIIISH-SQUIIISH!
A warm, endless stream squirted across his face, drenching his cheeks, chin, neck in sweet, sticky fluid.
She shuddered, tail thrashing, pussy pulsing against his tongue.
They collapsed, panting, slick with sweat and cum.
…
Both of them laid tangled on the floating bed, breath ragged, skin flushed and shining.
The air was thick with the scent of sex and vanilla.
Rito's cock still twitched, half-hard, slick with Lala's saliva.
Lala's pussy glistened, swollen, dripping with her own release.
She rolled onto her back, legs parting.
Her tail curled around his wrist, tugging him closer.
Her voice was soft, trembling with nerves and need.
"Rito… I'm ready."
She bit her lip.
"I want you inside me."
Rito's heart slammed against his ribs.
He knelt between her thighs, hands shaking as he lined himself up.
The head of his cock brushed her entrance—wet, hot, pulsing.
They both gasped.
He pushed in.
Slow.
Tight.
The first inch stretched her, her walls clenching around him like a fist.
Lala's eyes widened, a sharp hiss escaping her lips.
"R-Rito… it's… big…"
He froze.
"Are you okay?"
She nodded, tears pricking her eyes.
"Keep going… please…"
He thrust deeper.
Shluck-Shluck!
Her pussy sucked him in, inch by inch, until he was buried to the hilt.
They both moaned.
"Haaaah…!"
He started moving.
Slow at first, then faster.
shlick-shlick-SCHLICK-SCHLICK!
The bed creaked under them.
Lala's tail wrapped around his waist, pulling him deeper.
Her nails dug into his back.
"R-Rito… harder…!"
He obliged immediately.
Hips slamming.
Thwap-Thwap-THWAP-THWAP!
Her breasts bounced with every thrust.
Her pussy squelched, gushing around his cock.
"AHH— AHH— RITO—!"
He flipped her onto her stomach.
Doggystyle.
Grabbed her tail, yanked.
She screamed.
"YES— THERE—!"
He pounded harder.
Thwap-Thwap-THWAP-THWAP!
Her ass rippled with every impact.
Her pussy clenched, milked him.
"I'm— cumming—!"
Rito slammed home one final time.
His hips locked against hers, buried to the hilt.
Every muscle in his body tensed — abs carved into steel, thighs quaking, toes digging into the mattress.
A low, guttural growl tore from his throat:
"LALA—!"
He exploded.
A torrential flood of thick, scalding cum gushed into her womb like a broken dam.
SPLURT-SPLURT-SPLURT-SPLURT-SPLURT!
Each pulse was violent, endless, relentless.
The first rope slammed against her cervix with a wet thud, filling her so fast her belly visibly swelled—a soft, rounded bulge rising under her skin.
The second, third, fourth were heavy, syrupy waves that stretched her walls, overflowed her entrance, and gushed back out around his shaft in warm, sticky rivers.
Shluck-Shluck-SHLUCK-SHLUCK!
The excess poured down her thighs in thick, pearly streams, pooling on the sheets with soft plip-plop-plip.
Pulse-pulse-pulse — his cock kept spasming, squeezing out final oozing globs that dripped from her stuffed pussy in slow, lazy strands.
Lala's eyes rolled back.
Her tail thrashed wildly, heart-shaped tip clenching around his wrist.
"R-RITO— IT'S SO MUCH—!"
Her voice cracked into a shaking scream, body convulsing.
Cum leaked from her in a continuous stream, soaking the bed, dripping off the edge in heavy splat-splat-splat sounds.
Rito collapsed forward, forehead against hers, breath ragged.
Lala's belly gurgled softly, still bloated, cum sloshing inside her with every tiny movement.
A Golden Heart Seal #1 glowed on her lower abdomen, pulsing with light.
Lala's eyes widened.
"The Engagement Beam… it's real…"
They collapsed, panting.
Rito pulled her close, kissing her forehead.
Lala curled into his chest, voice soft.
"I feel… complete~♡ I belong to you forever, Rito~♡"
Hours later.
They had fucked again.
And again.
Missionary.
Cowgirl.
Against the wall.
Rito's stamina and lust was insane.
Lala's Devilukean physique matched him.
Shlick-Shlick-SCHLICK!
Thwap-Thwap-THWAP!
Glurk-Glurk-GLURK!
Cum everywhere.
The bed soaked.
The walls splattered.
…
POV Switch.
Mikan, Sachie, and Mami stood frozen outside the door.
They'd returned early, arms full of groceries.
The sounds hit them first.
Thwap-Thwap-THWAP!
"RITO— HARDER—!"
SQUIIISH-SQUIIISH!
Mikan's face went white.
'My brother… with her… in our house…'
'He promised… just pancakes…'
Sachie's eyes gleamed, hand over her mouth.
'He's… huge even when inside her, I can see his shape… I want that…'
Mami's knees buckled.
'Onii-san… inside Lala… I'll be next…'
They fled in silence.
…
POV Normal.
The sun dipped low, painting the room in amber.
Rito and Lala lay tangled, sweat-slick, cum-soaked.
The bed was a wreck—sheets twisted, pillows on the floor, air thick with sex.
Rito stared at the ceiling, mind reeling.
'I took her virginity. I'm… completely different now.'
Lala nuzzled his chest, her voice soft.
"Rito~ I feel full~♡
Let's do this every day… Husband-dono~♡"
The sun had slipped behind the rooftops when the front door slammed downstairs, the sound sharp enough to cut through the haze of sweat and satisfaction.
Mikan's voice rose, edged with something brittle.
"Dinner's ready."
Rito and Lala froze mid-breath.
They exchanged a look—his eyes wide, hers sparkling with the afterglow of secrets.
Clothes came on in hurried silence: shirts tugged over damp skin, shorts pulled up over sticky thighs, cum still drying in faint, glistening patches.
The air between them hummed with unspoken promises.
Downstairs, the dining table waited like a stage set for judgment.
Mikan stood at the head, arms folded so tightly her knuckles blanched.
Her eyes were red-rimmed, not from tears but from the effort of holding everything in.
Sachie and Mami sat opposite each other, hands folded in their laps, stealing glances that darted like frightened birds.
Pancakes from breakfast—reheated, edges curling—sat in the center.
No one reached for the syrup.
The silence stretched, thick and suffocating.
Forks scraped plates with soft scritch-scratch sounds.
No one spoke.
After, Sachie and Mami rose.
They hugged Mikan goodbye—quick, awkward squeezes that lingered a fraction too long.
Lala floated to Rito, tail curling around his wrist like a ribbon.
"Tomorrow… more research~♡"
Her voice was light, but her eyes held his for a beat longer than necessary.
Mikan watched them leave.
The door clicked shut.
The house fell quiet, the kind of quiet that presses against the eardrums.
Rito found her in the kitchen, sleeves rolled to her elbows, hands submerged in soapy water.
The dishes clinked softly as she scrubbed, harder than needed.
He stood behind her, hands hovering before settling on her shoulders.
"Mikan…"
She didn't turn.
Her voice was small, scraped raw. "
Just… go to bed, Rito."
He lingered a moment, then let his hands fall.
His footsteps faded up the stairs.
And thus, one of the most memorable days of Yuuki Rito came to an end.
