Her eyes flicked towards the wooden box made up of crystal jade wood, and then back to Su Mu, a hint of nervous excitement in them. 

"I have a little collection," she began, her thumbs gently stroking Su Mu's collarbones. 

 "Collection?" she echoed, her curiosity deeply piqued. This whole evening had been a series of delightful surprises, and she had a feeling this one would be no different.

Xu'er bit her lip for a moment, a flicker of something unreadable in her dark eyes, something more than just anticipation, maybe a touch of cunningness. "Come see."

She took Su Mu's hand again and led her a few steps to the small, ornate side table. 

The crystal jade wood of the box seemed to glow faintly in the amber light, looking ancient and precious. 

Xu'er's fingers, slender and sure, went to a small, almost invisible clasp. 

With a soft click, she lifted the lid.

A puff of distinctively cold air wafted out, kissing Su Mu's face and carrying a faint, sterile, almost metallic scent, quickly overpowered by the sandalwood and vanilla of the room. 

Su Mu leaned closer, her gaze drawn to the contents within.

Inside, resting on a bed of what looked like black velvet, were three small, sleek devices that looked like something out of a futuristic medical drama. 

They were auto-injectors, gleaming with a dull metallic sheen, each designed with an elegant, ergonomic curve. 

Next to each injector, in a perfectly fitted compartment, was a slender vial containing a liquid that pulsed with a soft, internal light. 

Each liquid was a different, vibrant color: one a brilliant, fiery orange like a captive sunset; another a deep, electric sapphire blue that seemed to shift and swirl; and the third a vivid, almost fluorescent emerald green, reminiscent of the comforter on the bed.

"This?" Su Mu questioned instinctively, her voice barely a whisper. 

She looked from the glowing vials to Xu'er, whose eyes were wide and shining with an unmistakable eagerness. 

Xu'er looked like a child about to share her most treasured, secret toy.

As Xu'er watched her, a breathless anticipation on her face, Su Mu felt a familiar, subtle tingle at her temples.

Her Insight Digitization activated almost on its own, drawn by the unusual energy signature of the items in the box. 

Information flooded her mind:

[Name: Transformation Vials ]

[Level: ??]

[Type: Temporary Humanoid Enhancement - Cloud Beast Gene Integration (Prototype)]

[Source: Modified Feline Cloud Beast Gene Sequences (Panthera Nebula Variant - 'A')]

[Function: Induces temporary, controlled polymorphic adaptation in human subjects. User manifests enhanced humanoid characteristics resonant with the base Cloud Beast gene profile. Notable physiological boosts include significantly increased strength, stamina, speed, and heightened reflex arcs.]

[Duration: Approximately 2-3 hours, subject to individual metabolism. No permanent alteration to the baseline gene chain. Reversion is complete.]

[Specific Modification: These particular admixtures have been further refined. Standard combat enhancements are secondary. Primary modification significantly amplifies somatic sensory input and neural reflex sensitivity. Nerve endings experience a temporary hyperinnervation, drastically increasing tactile perception, pleasure responses, and overall sensory acuity. Designed for... heightened experiential states.]

[Additional Enhanced Attributes:]

[Nocturnal Adaptation (Enhanced Low-Light Vision): Grants superior visual acuity in minimal lighting conditions. Details, textures, and subtle movements become exceptionally clear, even in deep shadow, rendering the environment and individuals within it with heightened definition.]

[Pheromonal Acuity (Heightened Olfactory Perception & Subtle Emission Modulation): Drastically sharpens the ability to perceive and differentiate nuanced pheromonal signals, particularly those related to emotional states, attraction, and arousal. May also subtly modulate the user's own pheromonal signature, enhancing non-verbal communication of desire and receptiveness.]

[Kinetic Flow: A remarkable increase in bodily agility, suppleness, and graceful coordination, allowing for fluid, instinctual, and effortlessly articulate movement.]

Su Mu's eyes widened slightly as she processed the last part. Heightened experiential states. 

Increased nerve reflexes to enhance sensitivity. Her gaze flicked back to the glowing vials. 

She looked at Xu'er, who was watching her with an almost baited breath.

"Xu'er, what exactly are these?" Su Mu asked, her voice still hushed, a whirlwind of thoughts like caution, intense curiosity, and an undeniable thrill swirling within her.

Xu'er's smile was a mixture of excitement and a touch of shyness. 

"They're… well, they're a bit of a hobby. Something special I came across a while ago. You know how some people collect rare wines, or art?" 

She gestured to the box as she picked up the injector beside the fiery orange vial, handling it with familiar care. 

"These are from… well, let's just say they're from a Black market merchant."

"They temporarily give you some of the... attributes of certain Cloud Beasts. Not the full change, nothing dangerous or permanent, I promise!" she added quickly, seeing the complex look on Su Mu's face. 

"Think of it more like... borrowing their senses for a little while, not more than two to three hours."

"Their strength, speed, reflexes, but mostly…" Her voice dropped, becoming huskier, more intimate. "...their sensitivity. Especially their sensitivity."

She set the orange injector down carefully, and her fingers hovered over the sapphire blue one. 

"These specific ones, the ones I have here, are all from different kinds."

"And they've been specially tweaked. They make everything feel… every touch, every sensation, it's like your whole body becomes active, in the best possible way."

Xu'er looked directly into Su Mu's eyes, her own dark pools filled with a hopeful, eager light. 

"I've never… shared them with anyone before, Missy. They're very precious to me."

"But with you… tonight… everything with you feels different, so much more intense already. I just thought…"

"I wondered if you'd be curious enough to try? With me?" Her gaze was open, making Su Mu's chest ache with a sudden surge of affection. 

"Imagine," she whispered, leaning a little closer, "everything we've already felt, but amplified. Every kiss, every touch… a hundred times more powerful."

Su Mu's mind raced. Her own Empathic Siphon already made her experiences with emotion and pleasure incredibly potent. 

To add this on top? The idea was both terrifying and exhilarating. 

The feline aspect… she thought of their predatory focus, their uninhibited sensuality. 

And Xu'er wanted to share this with her. 

It was an incredible gesture of intimacy.

She looked at the three vials, the orange, the blue, the green, each pulsing with a soft light. 

She thought of Xu Er's earlier words about her being different from other women she'd been with. 

A slow smile spread across Su Mu's face, mirroring Xu Er's eagerness. 

The thrill was winning out over any apprehension. 

With Xu'er, she felt brave enough to explore anything. "You want me to become… a little wild?" she asked, her voice soft and teasing.

"Something like that, Missy.." Xu'er's answering grin was dazzling. She let out a shaky little laugh. "So? Are you in? We can choose your… favorite type… Among the three."

Su Mu's gaze drifted over the vials again. 

The fiery orange seemed to call to a bold, passionate side of her. 

The sapphire blue hinted at something sleek, perhaps mysterious and deep. 

The emerald green felt connected to the lushness of the room, promising a more grounded, deeply sensual experience.

"Which one," Su Mu asked, her voice a little breathless, "is your favorite?"

Xu'er's eyes sparkled. "They all have their charms. But tonight…"

"For the first time, together…" She reached into the box and her fingers hovered, then decisively picked up the auto-injector beside the sapphire blue vial. 

"I think this one... It'll make you feel incredible… fluid."

"And the sensitivity is just exquisite." She held it out slightly, the blue liquid swirling within its glass chamber like a tiny captured galaxy. 

"It reminds me a little of Shadow LYNX's incredibly graceful and intensely acute awareness of everything around it."

Su Mu looked at the injector, then back at Xu'er's expectant face, and it was totally irresistible. 

"Alright, Professor Xu Er," she said, a playful tremor in her voice. "Show me how it's done."

Xu Er's smile widened, full of delight and anticipation. 

"Wonderful! Now, this won't hurt, just a tiny prick. The best place is usually the inner thigh or the upper arm."

"Since we're aiming for a full sensory experience..." Her gaze flickered down Su Mu's body with a heat that made Su Mu's skin tingle, lingering for a moment on her thighs. "...perhaps the thigh would be most… effective?"

Su Mu felt a blush creep up her neck, but she nodded, her heart racing. "Okay."
