Xu'er lifted it out with the care of someone handling an unpredictable, priceless artifact.

It wasn't a solid object, but a small, disc-shaped device that seemed to hold a swirling, semi-liquid mass of pure darkness.

Within the darkness, faint, silvery filaments sparked and shifted, like neurons firing in a living brain.

It seemed to breathe and had a texture.

As Su Mu watched, a tendril of the substance detached from the main mass, pressing against the inside of the containment unit, seeming to reach towards Xu'er before melting back into itself.

It moved like something sentient, a captive symbiote.

It was hypnotic and vaguely unsettling, yet incredibly fascinating.

"What… is that?" Su Mu whispered, her voice husky.

Her bluish-silver tail, which had been resting peacefully, gave an involuntary, inquisitive twitch against the sheets.

Her ears, pointed and alert, were angled directly at the strange object in Xu'er's hands.

Xu'er handled the device with a practiced, confident care that spoke of familiarity.

"This, my sweet Missy," she said, her voice full of a scientist's passion and a lover's promise, "is my most prized prototype."

"It works on a similar principle to the transformation shot you took, but it's a much more specialized application."

As she brought it closer, Su Mu felt that familiar tingle at her temples as her Insight Digitization activated, hungry for the strange energy signature.

The data that flooded her mind was even more shocking than the transformation shots.

[Name: Bio-Kinetic Symbiote (Prototype V3.7)]

[Level: ??]

[Source: Genetically-Engineered Parasitic Cloud Beast (Symbiotic Strain)]

[Function: A bio-organic, quasi-sentient organism designed for temporary symbiotic bonding with a host. When activated, it extrudes from its containment field and forms a fully functional, controllable appendage on the host's body. The primary intended form is a phallic structure, resembling human dick.]

[Attachment: Dermal-neural interface. Attaches to the lower abdomen via micro-filaments, integrating with the host's nervous system for direct mental control.]

[Additional Attributes:]

[Haptic Feedback: Transmits all tactile sensations experienced by the appendage directly back to the host's neural pathways. The host feels what the appendage touches.]

[Morphing Capability: Can subtly alter shape, texture, and firmness based on the host's mental commands.]

[Thermoregulation: Can be mentally willed to be warm or cool.]

[Bio-Luminescence: Internal filaments can glow based on the host's emotional state or specific commands.]

She brought it closer to the bed, allowing Su Mu to see it more clearly. The dark mass inside pulsed with a slow, rhythmic light.

"It's a parasitic symbiote, bio-engineered from a very unique kind of Cloud Beast," Xu'er explained, her words simple, but the concept behind them vast.

"Think of it like… a living extension. It doesn't permanently bond, of course."

"The device provides the power and the neural interface to control it. When activated, the symbiote leaves its containment and forms… well, whatever the user desires."

Su Mu's mind reeled. A living, shape-shifting prosthetic. "It… attaches to you?"

"Perfectly," Xu'er confirmed, her eyes gleaming.

"It melds with the wearer's skin, reading their neural impulses, their desires. It becomes a part of you, for a time. It feels what you feel."

"And," she added, her voice dropping to a conspiratorial whisper, "I can make it feel however I want."

"Like, I can change its length, its thickness, its texture… I can make it warm or cool. I can make it vibrate or pulse. It can be as soft as silk or as firm as stone. It's a prototype, so it has… multiple functions for testing."

She looked from the device to Su Mu, who was now sitting up slightly, her transformed body a canvas of rapt attention.

"It's the ultimate tool for pleasure, Missy. Both for the one wearing it and for the one receiving it. The sensory feedback is… unparalleled."

The words washed over Su Mu with the force of a tidal wave.

To be touched by something like that, something alive and responsive, nothing short of a real dick, guided by Xu'er's desires and expert knowledge… it was beyond anything she could have ever imagined.

"Fuck!!"

The line between technology, biology, and pure pleasure was completely blurred in her mind.

The concept was so far beyond anything she had ever known that her mind struggled to grasp it, yet her transformed body understood on a much more primal level.

Not long back, he used to have a real one himself… Yet, it's completely different now.

"You want to… wear it?" Su Mu asked, her voice barely audible.

Internally, she wrestled with the decision: should she accept Xu Er's proposal?

Xu'er's smile was slow and achingly sensual as she looked at the confused Su Mu.

"Tonight," she purred, "I thought I would."

Her gaze traveled over Su Mu's naked, fur-covered body, lingering on the valley between her legs.

"I want to feel you, Missy. Deeply. And I want you to feel me. Every pulse, every thought. With this… we can."

She set the harness down gently on the bed between them. The dark substance inside swirled, as if it could sense the rising tension in the room, as if it were eager to be released.

Su Mu's mind raced, a whirlwind of her past life as a man colliding with her current reality as a woman, now transformed into something even more.

The sight of the symbiotic device, a living tool of pleasure, was both deeply alien and strangely, profoundly resonant.

Her body, already thrumming with heightened senses, seemed to answer the silent invitation before her mind could form a coherent thought.

Her bluish-silver tail gave a slow, deliberate sweep across the velvet comforter, a gesture of profound curiosity and acquiescence.

A radiant smile broke across Xu'er's face. Before Su Mu could decide on whether to accept or not, she placed the small disk on her own lower abdomen.

"Okay," she whispered, mostly to herself. "Just relax."

Su Mu watched, mesmerized, her own breathing growing shallow as Xu'er's fingers, steady and deliberate, pressed the center of the dark, disc-shaped device.

A soft, internal light flared within the swirling darkness, pulsing once, twice, before the containment field around the mass seemed to shimmer and then dissolve.

The black substance, no longer constrained, didn't simply pour; it flowed out onto Xu'er's skin like thick, liquid silk, spreading with a mesmerizing, organic grace.

It was seamless, beautiful, and utterly alien.

Shimmering silver filaments, fine as spiderwebs, immediately began to spread from the main mass, branching out across Xu'er's lower abdomen.

Su Mu watched, transfixed, as they sank into Xu'er's skin, anchoring the substance with astonishing speed and precision.

As the symbiote began to bond, a soft gasp of intense pleasure escaped Xu'er's lips, almost a moan.

Her body gave a subtle twitch, a delicious shiver that rippled through her from the sheer intimacy of the connection forming.

Her head fell back for a brief moment, a faint sheen of sweat appearing on her brow, her eyes fluttering closed as she absorbed the feeling.

It was clearly not painful, but deeply, profoundly sensual, a new kind of integration that resonated with her own adventurous spirit.

Then, the symbiote began its true transformation.

The dark mass, now fully attached to Xu'er, flowed and gathered, rising from her skin silently.  Newest update provided by NovєlFіre.net

It elongated, thickened, shaping itself with an almost conscious fluidity.

It formed a perfect, long, elegant, and unmistakably phallic structure like a human dick, rising from Xu'er's body like a dark, living sculpture.

The surface of this new organ wasn't uniform; it had the soft, plush texture of smooth, dark velvet, absorbing the lamplight.

And within its depths, the silvery filaments that had anchored it to Xu'er's skin now pulsed with a soft, ethereal blue light.

It was beautiful, strange, and breathtakingly erotic, looking nothing short of a perfectly formed, exquisitely responsive living extension.

Su Mu's own breath hitched in her throat, her transformed body vibrating with a mix of awe and burgeoning desire.

Her new feline eyes, wide and luminous, devoured the sight.

After a moment of internal adjustment, Xu'er let out a shaky breath, her eyes fluttering open, now dark and heavy-lidded.

She looked down at the new organ, now a seamless, living part of her, and a slow, triumphant smile spread across her lips.

With a simple thought, she flexed it. It moved, slightly swaying with a fluid, almost conscious life of its own, an incredible testament to the bond it shared with her.

Xu'er's gaze lifted to Su Mu, a triumphant, deeply sensual gleam in her eyes.

"Hello there," she murmured, her voice husky with the echoes of connection, "my new companion."

The statement was directed at the symbiote, but her gaze was fixed on Su Mu, a clear promise of what was to come.

All thought was replaced by pure, instinctual observation.

The sight of that beautiful, strange dick like organ, moving with such fluid grace at Xu'er's command, pulsing with a soft blue light, was the most shockingly erotic thing she had ever witnessed.

A deep, primal purr started in her chest, a rumbling vibration that she felt down to her bones.

Xu'er's smile widened as she heard the deep, resonant purr.

She took in Su Mu's wide, luminous eyes, the way her claws were unconsciously flexing into the bedsheets, the sensual sway of her tail.

Every part of Su Mu's body was broadcasting a clear, undeniable signal: fascination, arousal, and a deep, yearning curiosity.

"So," Xu'er said, her voice a low, intimate murmur that slid under Su Mu's skin. "What do you think of my... new companion, Missy?"

Su Mu swallowed, her throat suddenly dry. Words felt entirely inadequate.

She could only shake her head slightly in awe, her sapphire gaze fixed on the living appendage.

"It's… it's…" she stammered, "…unreal."
