Inside the fitting room of a women's lingerie store, Kuro was fastening the lingerie bracelet straps from behind with gentle, careful movements, adjusting each detail without causing Tamamo even the slightest discomfort.
Meanwhile, Tamamo stood still, allowing him to finish.
Her gaze was fixed on her own reflection in the mirror before them.
The reflection revealed soft pink lingerie elegantly adorning her figure—delicate lace, a sheer veil overlay, and feminine details perfectly matching her pink hair.
A faint blush spread across Tamamo's face.
Not entirely from embarrassment—more like a small flame just brushed by a warm breeze.
Once everything was properly fastened, she slowly turned to face Kuro.
Her arms immediately slipped around his neck, pulling the distance between them much closer.
"How is it?" she asked softly.
Her gaze was gentle, though it carried a trace of unease that rarely surfaced.
"Does it… suit me? Do you like it?"
Kuro gave a small smile.
"Yes, I do. And you look good in anything, Caster."
For a moment, Tamamo froze.
Then her expression softened, like thin ice slowly cracking beneath warm embers.
"Hehe…"
A quiet laugh escaped her lips.
"You really do know how to catch a woman off guard."
Her face slowly leaned closer.
The distance between them thinned until it quietly disappeared.
Warmth flowed naturally between them—like lava slipping through cracks in stone, calm yet inevitable.
Not an eruption.
Just a steady warmth moving of its own accord, like two serpents tracing each other's presence through a silent marsh.
Kuro's eyes widened slightly for a moment.
But soon enough, he followed the rhythm as well, allowing that subtle flow to take shape on its own.
"Slurp... lick... nggh..."
At times, they drifted slightly apart.
Just enough for that thin boundary to briefly reform.
Only to draw close again.
Like two serpents dancing in a pattern understood only by themselves—coiling, drawing near, then pulling away before finding each other again.
"Aaa... hhh... hhh..."
Tamamo's breathing gradually became heavier.
Her thoughts felt slightly lighter, like snow slowly losing its shape beneath foxfire burning far too close.
Her eyes were half-lidded.
The pink flush on her cheeks deepened.
"Mm…"
She let out a soft breath.
"…What about my kiss…"
Tamamo opened her eyes slightly, looking at Kuro with a faint smile.
"...did you like it too, darling?"
Kuro let out a soft laugh, almost amused.
There was something about that closeness—warm, delicate, and faintly dangerous—like the bite of a serpent that caused no wound, yet left behind a trail of heat spreading far deeper than expected.
The sensation was enough to subtly alter his expression.
Sharper.
A little more alive.
"Never disappointing," he replied at last. "You have a taste I like, Caster."
Right after that, Kuro's left hand moved slowly.
Like a serpent discovering the warmest path through midnight grass, his touch traced along the surface with a rhythm almost too calm.
"Hngg..."
A quiet sound slipped from Tamamo's lips.
Her body swayed slightly, nearly losing balance as her knees weakened.
By reflex, she grabbed onto Kuro more tightly, making him the only anchor keeping both her body and thoughts grounded.
As if without him, she might truly drift too far away.
Meanwhile, Kuro's right arm continued to hold Tamamo carefully.
Steady, yet gentle.
Like an ancient serpent-shaped artifact—beautiful, but far too delicate to handle carelessly.
His face leaned closer to Tamamo's ear, still hidden beneath illusion.
"Just remove it," he whispered softly. "I can restore these clothes as if they were brand new."
A faint smile crossed his lips.
"Besides… we already bought them, didn't we?"
Tamamo swallowed.
Those words struck her like a small spell directly into the center of her foxfire.
As if something warm and fluid surged rapidly through her—like serpent venom finally returning to its original source.
"—!?"
The heat rose too quickly.
And just before her voice could break into something far less controlled—Tamamo hurriedly bit Kuro's shoulder.
Not to hurt him.
More like a final attempt to suppress the rising wave of warmth threatening to spill over.
"Aah... hahh... hhh..."
Her breathing quickened.
"…You're really terrible," she murmured softly between the small bite.
Yet her tone sounded nothing like a complaint.
This time, without saying a single word, Kuro slowly adjusted Tamamo's position, guiding her until both of her palms rested against the mirror before them, her back bent slightly at a right angle.
The cold surface of the mirror pressed directly against her skin, creating a strange contrast with the lingering heat that had yet to truly fade.
And yet, the blush on her face only deepened further. Even the fox ears hidden beneath her illusion pulsed subtly, betraying her far more honestly than her expression did.
Slowly, Kuro revealed another layer.
Like a serpent patiently uncovering something hidden beneath dense leaves.
Then, in the next moment—an unfamiliar sensation slipped into a path even foxfire itself had not prepared for.
Not rough.
If anything, far too subtle.
Far too unexpected.
Like a serpent finding its way into forbidden territory without permission.
Tamamo's eyes widened instantly.
"—!?"
Her right hand quickly flew to cover her own mouth before any uncontrolled sound could escape.
Kuro smiled faintly at her reaction.
"This time, you don't have to hold your voice back," he said casually. "I already set up a small bounded field around this room."
Tamamo stared at him through the mirror's reflection, clearly unsure whether to feel relieved or even more flustered.
"You really are…" she murmured softly behind her fingers.
But the sentence never finished.
Because after saying those words, Kuro began to move.
Slowly.
Steadily.
Consistently.
Like a small flame patiently licking across ice, allowing it to melt little by little without ever rushing.
Each motion felt like the path of a serpent circling its prey—not to harm it, but to ensure no trace of cold could remain.
"mmha... hnaa... hhh..."
Tamamo's breathing gradually became uneven.
Without realizing it, her eyes rolled upward slightly, and the tip of her tongue slipped past her lips.
The surface of the mirror before her began to fog faintly beneath the warmth of her breath.
"AHH…"
A small sound finally slipped free, far softer than she expected.
Her body tensed slightly, then gradually weakened again, like snow realizing it was losing against summer.
Kuro let out a small chuckle as he watched Tamamo's reflection in the mirror.
"See?" he said softly. "Your expression is pretty cute, you know?"
Tamamo froze for a moment.
Her gaze slowly shifted toward her own reflection.
Flushed cheeks.
Half-dazed eyes.
Warm breath leaving faint fog against the glass.
And an expression far more vulnerable than she was used to seeing from herself.
"Ah…"
A small sound escaped her lips.
Her face reddened even more.
"You're really making me watch all of this?" she murmured softly, almost like a complaint—though her tone sounded far more embarrassed than genuinely upset.
At the same time, as if adding more wood to an already burning fire, Kuro's hands moved again.
Like two serpents instinctively understanding their separate paths of warmth.
His right hand drifted upward, tracing along hidden lines beneath fabric and lace, following the areas most reactive to heat—not roughly, but with a light rhythm disruptive enough to steal her concentration.
Meanwhile, his left hand moved lower.
Calm.
Steady.
Consistent.
Like a serpent gliding patiently across the surface of a marsh.
The two flows worked together, turning already difficult warmth into something far harder to manage.
As though three different poisons were now flowing at once through Tamamo's foxfire pathways, assaulting her defenses one after another without giving her even a moment to recover.
"Ngyu... nnn... hhh... aaa.. haa... haa..."
Tamamo's breathing grew increasingly erratic.
Her vision became harder and harder to steady, until even her own reflection in the mirror began to blur.
Eventually, her face came to rest against the mirror's surface, as if her strength had slowly drained away, while the tip of her tongue—still slightly extended without her noticing—brushed lightly against the cool glass.
"Dar… ling…"
Her voice nearly collapsed.
Her body trembled faintly, like ice being forced to melt faster beneath a flame far too patient.
Kuro only smiled softly.
His expression remained far too calm.
Almost as if he was quietly enjoying the chaos slowly overtaking Tamamo.
"Caster," he whispered near her ear. "If this keeps going…"
His eyes met Tamamo's through the mirror.
"…you're really going to melt."
