The room is dim, lit only by the soft glow of a bedside lamp.
The scent of jasmine shampoo and warm soap still clings to the air, mixing with the clean smell of freshly washed skin.
The covers are pulled up to their chins, and Haruno’s arm is wrapped around Kouma’s small frame, her fingers threading through his damp black hair.
He is curled against her chest, his cheek pressed to the soft swell of her breast through the thin fabric of her bathrobe.
She can feel his breath, warm and even, against her skin.
Her other hand rests on his back, tracing lazy circles between his shoulder blades.
“Kouma-kun,” she murmurs, her voice soft and drowsy.
“You’re so warm.”
He hums in response, nuzzling closer.
His voice is small, innocent.
“Haruno-nee…
do you always see me as a child?”
The question catches her off guard.
She pauses, her fingers stilling in his hair.
“Of course,” she says, her tone gentle but certain.
“You’re my little b[rother].
My good boy.”
He smiles against her chest, but there is something different in his eyes when he looks up at her.
A flicker of something older, something knowing.
“Good boy,” he repeats, and the words hang in the air.
Then he closes his eyes.
Haruno feels it before she sees it.
A warmth radiates from his body, a faint golden glow that seeps through the fabric of his robe.
She blinks, confused.
“Kouma-kun?
What’s—”
Her words die in her throat.
His body shifts beneath her hands.
The small frame she was holding expands, broadens.
She feels muscle and bone reshaping, growing.
His shoulders widen, his chest thickens.
The robe strains against his new form, the fabric pulling taut over a much larger frame.
She pulls back, her eyes wide.
His face changes.
The soft, boyish features sharpen.
His jaw becomes more defined, his cheekbones higher.
His eyes, when they open, are no longer innocent.
They are deep, knowing, burning with a heat that makes her breath catch.
Horns sprout from his temples, curling back like a ram’s, dark and smooth.
A tail emerges from the base of his spine, long and muscular, the tip shaped like a spade.
It flicks once, twice, brushing against her calf.
And then she sees it.
The robe has fallen open.
His body is no longer that of a child.
He is a man.
Broad shoulders, defined chest, a trail of dark hair leading down from his navel.
And his cock.
God, his cock.
It is thick.
Thicker than any she has ever seen.
The shaft is veined, the veins raised and prominent, creating ridges that catch the dim light.
The glans is large, bulbous, a deep flushed pink against the darker skin of the shaft.
It stands erect, heavy, the weight of it pressing against his lower stomach.
She can see every detail: the way the skin is stretched taut, the way the veins pulse with his heartbeat, the way the tip glistens with a bead of precum.
Her breath catches.
Her mind screams.
This is your b[rother].
Your little b[rother].
You just bathed him.
You dried his hair.
But her body…
Her nipples harden beneath the thin fabric of her robe, pressing against the material, aching.
Between her thighs, she feels a warmth spreading, a dampness that makes her clench her thighs together.
Her pussy is getting wet.
She can feel the slickness, the way her folds are already parting, preparing.
Why?
she asks herself.
Why is my body reacting like this?
She looks at him.
At his broad shoulders, his defined chest, the trail of dark hair leading down his stomach.
At his cock, thick and veiny, the raised veins creating a texture that she can already imagine pressing against her inner walls.
The glans is large, bulbous, glistening with a bead of precum that catches the lamplight.
That’s not my little b[rother], she tells herself.
That’s…
that’s a man.
But it is him.
The same eyes, the same smile, the same warmth.
Just…
older.
More.
Her breath is shallow.
Her heart pounds against her ribs.
Between her thighs, she feels a wetness spreading, a heat that makes her clench her thighs together.
Her pussy is getting wet.
She can feel the slickness against her folds, the way her body is already preparing for something her mind is still rejecting.
This is wrong, she thinks.
He’s my b[rother].
My little b[rother].
I raised him.
I changed his diapers.
I taught him how to tie his shoes.
But her body does not care.
Her nipples are hard, aching, pressing against the fabric of her robe.
Her pussy is throbbing, empty, hungry.
She can feel the pulse between her legs, a rhythmic ache that demands to be filled.
Why am I getting wet?
she asks herself, but she knows the answer.
She has always known.
The way she looked at him a little too long.
The way she held him a little too close.
The way she felt a strange thrill when he called her “nee-chan” in that soft voice.
She wanted this.
She just never admitted it.
Kouma moves slowly.
He does not rush.
He reaches out, his hand cupping her cheek.
His palm is warm, his fingers long and strong.
He tilts her face up, forcing her to meet his eyes.
“Haruno-nee,” he says, and his voice is deep now, rich, commanding.
It sends a shiver down her spine.
“I have always wanted you.”
He leans in, pressing his lips to her neck.
She gasps.
His mouth is hot, his tongue tracing a path from her jaw to her collarbone.
He bites down gently on her earlobe, tugging, and she moans before she can stop herself.
“I have watched you,” he whispers against her skin.
“I have smelled your arousal when you thought I was asleep.
I have seen the way you look at me when you think I am not paying attention.”
She shivers.
She should push him away.
She should tell him to stop.
This is wrong.
This is her b[rother].
But her body arches into him.
Her hips press forward, seeking contact.
Her breath comes in ragged gasps.
“Haruno-nee,” he murmurs, his lips brushing her ear.
“Do you want me too?”
She looks at him.
At his horns, dark and elegant.
At his tail, curling around her waist, the tip resting on her hip.
At his eyes, deep and burning with desire.
And she stops fighting.
She reaches up, her fingers tracing the curve of his horn.
It is smooth, warm, alive.
She slides her hand down, cupping his cheek, feeling the stubble on his jaw.
He is real.
He is here.
And he wants her.
She pulls him down and kisses him.
It is not a gentle kiss.
It is hungry, desperate, a collision of lips and tongue and teeth.
She tastes him—warm, sweet, familiar and foreign all at once.
Her tongue slides against his, and she moans into his mouth.
Her hands move, exploring.
She traces the base of his horns, the curve of his shoulders, the hard planes of his chest.
She pushes his robe off his shoulders, and it falls away.
She is naked beneath hers, and she lets it fall open, baring herself to him.
Her hands find his cock.
She wraps her fingers around the shaft, and she gasps.
It is thick, so thick her fingers barely meet around it.
The veins are raised, textured, a landscape of ridges and pulses beneath her palm.
She strokes him once, twice, feeling the weight of him, the heat of him.
The glans is smooth and slick, and she rubs her thumb over it, spreading the bead of precum.
He groans, low and deep, and the sound vibrates through her chest.
She looks up at him.
At his horns, his tail, his eyes.
At the man who was her little b[rother].
And she surrenders.
She lies back, pulling him with her.
The covers fall away.
They are both naked now, skin against skin.
She spreads her legs, and he settles between them, his weight pressing her into the mattress.
His cock rests against her thigh, thick and heavy, the veins pressing into her skin.
She is ready.
Nervous, but ready.
Aroused, but terrified.
But she wants this.
She looks into his eyes, and she whispers, “Kouma-kun.”
He smiles, and it is the same smile he has always had.
Soft.
Affectionate.
Loving.
“Haruno-nee,” he murmurs, and the name sends a shiver through her.
She is lying beneath him, naked, open, ready.
His cock is pressed against her thigh, and she can feel the heat of it, the weight, the texture of the veins against her skin.
Her pussy is wet, aching and waiting.
