"Good." Xu'er gestured towards the bed. "Why don't you get comfortable? Make yourself at home, Missy."

Su Mu walked towards the bed, the plush burgundy rug feeling incredibly soft beneath her bare feet. 

She sat on the edge, the emerald velvet comforter cool and inviting. 

The size of the bed, the opulence of the fabrics, the soft, golden light… It all felt incredibly decadent and exciting. 

She looked back at Xu'er, who was approaching with the sapphire blue injector held carefully in her hand, her eyes alight with an intoxicating blend of excitement and tenderness.

"Ready?" Xu'er asked softly, kneeling before Su Mu, so they were almost eye to eye. 

The scent of Xu'er enveloped Su Mu, making her feel slightly dizzy with anticipation.

Su Mu took a deep breath. "Ready."

Xu'er's touch was gentle as she reached for Su Mu's leg, her fingers warm against Su Mu's skin as she slightly adjusted the hem of Su Mu's pants, exposing the pale skin of her inner thigh. 

The simple touch alone sent a shiver through Su Mu that had nothing to do with cold. 

Xu'er produced a small, sterile wipe from a pocket, cleaning a small area with a focused intensity that was surprisingly arousing.

"Just a little sting, then…" Xu'er murmured, her gaze flicking up to meet Su Mu's, holding it for a long moment. 

Then, with practiced ease, she pressed the tip of the auto-injector against Su Mu's skin.

There was a tiny hiss, a fractional moment of cool pressure, and then a very faint prick, so slight Su Mu barely registered it. 

She felt the cool liquid disperse beneath her skin, a subtle thrumming sensation that began to spread outwards almost immediately.

Xu'er withdrew the injector, her eyes fixed on Su Mu's face, watching for her reaction. 

"There," she whispered. "Now we just… wait a moment."

Su Mu didn't have to wait long.

It started as a warmth, a tingling that began in her thigh and radiated upwards, spreading through her veins like a slow, delicious tide. 

It wasn't unpleasant; in fact, it was incredible… enlivening. 

Her skin began to prickle, not uncomfortably, but as if every single nerve ending was waking up from a long sleep, stretching and becoming exquisitely aware.

The colors in the room seemed to deepen, the amber light taking on a richer, more golden hue, the deep indigo of the walls becoming more vibrant, the jewel tones of the bedding almost glowing. 

She could hear the faint, almost imperceptible hum of one of the lamps, a sound she hadn't noticed before. 

Xu'er's breathing, soft and close, seemed to echo in her ears like a gentle rhythm.

"Oh," Su Mu breathed, her eyes wide as she looked at Xu Er. 

Xu Er's face, so close to hers, seemed even more beautiful, every detail sharpened, the tiny laugh lines around her eyes, the soft curve of her lips, the way a single strand of dark hair fell across her forehead. 

The scent of sandalwood from Xu'er's skin was suddenly intoxicating, so potent Su Mu felt she could almost taste it in the air.

Xu'er smiled, a slow, knowing smile. "Feeling it?"

Su Mu could only nod, speechless for a moment. 

Her own skin felt… electric. 

She lifted a hand, looking at her own fingers, and it was as if she could see the very texture of her skin in minute detail, feel the air currents moving around them. 

She touched her own arm, and the sensation was astonishing, the soft brush of her fingertips sent a cascade of sparks up to her shoulder.

"It's… incredible," Su Mu finally managed, her voice sounding slightly more resonant to her own ears. "Everything is… so much clearer than before."

"Exactly," Xu'er purred, her eyes gleaming. She took Su Mu's hand, her fingers lacing through Su Mu's. 

The contact was electrifying. 

Su Mu could feel the subtle texture of Xu'er's skin, the warmth of her palm, the slight pressure of each individual finger as if it were a profound caress. 

"Now imagine what happens," Xu'er whispered, leaning closer, her breath warm against Su Mu's ear, sending a shiver down her hyper-sensitive spine, "when I touch you."

Xu Er's voice, a husky whisper right against Su Mu's newly sensitized ear, sent a jolt through her entire system that was far more potent than any simple shiver. 

And then she did.

Her hand, the one still laced on top of Su Mu's breasts, squeezed gently. 

But to Su Mu, it felt like an exquisite pressure, every point of contact a tiny explosion of sensation. 

Xu'er's other hand lifted, her fingertips light as a breath, tracing the line of Su Mu's jaw, then drifting down her neck. 

"Eheaa….!!"Su Mu gasped, a soft, involuntary sound. 

The touch was feather-light, yet it seared a trail of fire across her skin, making the tiny hairs there stand on end, each one a conduit for pure, unadulterated feeling.

As Xu'er leaned even closer, her warm breath ghosting over Su Mu's lips, a strong, internal heat began to build within Su Mu. 

It wasn't just the flush of arousal; this was deeper, more primal, a sudden surge of energy that felt like her very cells were vibrating at a higher frequency. 

"Hanmmaaa…." It coiled in her belly, hot and urgent, then spread outwards below, a radiating warmth that intensified with every beat of her rapidly accelerating heart.

"Xu'er..." Su Mu whispered, her voice trembling as Xu'er's lips finally met hers. 

The kiss was electric, a thousand times more potent than before. 

Su Mu felt as if she could taste the very essence of Xu'er, feel the subtle textures of her lips in impossible detail, the warmth of her mouth an intoxicating inferno.

And then, the changes began, subtle at first, then undeniable.

The golden lamplight seemed to refract differently through Su Mu's eyes. 

When she blinked, the world sharpened with an almost painful clarity, colors becoming richer, deeper. 

She caught her reflection for a fleeting second in the dark wood of the headboard, and saw her pupils elongate, becoming sleek, vertical slits like a cat's, surrounded by an iris that now shimmered with an intense, luminous sapphire blue, mirroring the vial Xu'er had chosen.

A strange tingling started at the crown of her head. 

Su Mu's breath hitched as she felt something push through her silver hair, soft yet firm. 

Two new shapes, triangular and pointed, emerged, swiveling slightly, covered in a downy, bluish-silver fur that matched the new glow in her eyes. 

Her hearing sharpened dramatically; she could hear the faint rustle of Xu'er's clothes, the almost silent sigh of air from her nostrils, the distant thrum of the city outside the drawn velvet curtains, all with an astonishing new clarity. 

These new ears twitched, sensitive to every nuance of sound.

Her mouth felt different. 

Her tongue, already hyper-aware, traced the edges of her teeth and found them subtly altered. 

Her canines felt longer, sharper, pressing delicately against the inside of her lip. 

Not monstrous, but definitely… fangs. Small, elegant, but undeniably predatory.

A delicate, downy fur, the same mesmerizing bluish-silver as her new ears, began to spread across her skin. 

It wasn't thick or heavy, more like a fine, silken velvet that shimmered faintly in the amber light. 

It started on her forearms, peeking out from the cuffs of her simple knit top, then dusted her shoulders and traced the elegant curve of her collarbones. 

It softened her already curvy silhouette, making her skin feel incredibly soft and yet intensely alive to the slightest touch.

Her fingernails tingled, then hardened, extending slightly, curving into elegant, sharp claws that looked as if they were carved from mother-of-pearl with a faint blue sheen. 

She flexed her fingers, marveling at them. They didn't feel cumbersome, just… more capable.

The most startling change was the last. 

A warmth, a pressure, a strange new weight at the base of her spine. 

Su Mu gasped against Xu'er's mouth as she felt something unfurl, something long and sinuous, pushing against the constraint of her pants. 

A tail. 

A sleek, beautiful tail covered in the same soft, bluish-silver fur, perhaps three feet long, emerged, twitching and then swaying gently in the air behind her. It brushed against the velvet comforter, and the sensation was so new, so intensely felt, that Su Mu moaned, her hips instinctively arching.

The simple knit top and pants she wore now strained in places, hinting at the subtle but significant shifts in her body. 

The swell of her breasts seemed fuller, pressed against the hidden bustier, the new layer of soft fur making the fabric cling in a way that was incredibly suggestive. 

Her waist, already defined by the bustier, now seemed even more dramatically contrasted by the gentle curve where her new tail emerged, drawing the fabric of her pants taut.

Su Mu pulled back from the kiss, breathless, her sapphire cat-eyes wide as she tried to process the flood of new sensations, the reality of her altered body. 

She felt… powerful. Wild. 

And astonishingly, undeniably, incredibly aroused.
