One traced the line of Su Mu's neck, fingers dipping beneath the collar of her top, sending shivers down her skin. 

The other slid around Su Mu's side, her palm pressing flat against Su Mu's ribs, then moving upwards, her thumb brushing tantalizingly close to the underside of Su Mu's breast, right where the edge of the hidden bustier lay. 

Su Mu gasped into the kiss, arching slightly into the touch.

"Missy," Xu'er murmured against her lips, her breath warm and sweet with wine. "You make it very hard to think about moving."

"Good," Su Mu breathed back, her lips brushing Xu'er's with each word. 

"Don't think. Just feel." She kissed her again, deeply, pouring all her longing, all her burgeoning affection into it. 

She explored the curve of Xu'er's ear with her lips, then trailed soft kisses down her neck, inhaling Xu'er's unique scent.

A mix of her perfume and her own natural musk, a fragrance that was quickly becoming Su Mu's favorite.

Xu'er's head fell back a little, exposing more of her throat, a silent invitation that Su Mu eagerly accepted. 

She felt Xu'er's fingers clench in her hair, heard the soft, whimpering sounds she made, and a fresh wave of desire, mixed with a profound tenderness, washed over Su Mu. 

The Empathic Siphon hummed a powerful, resonant chord within her, feeding off this intense, mutual adoration.

After a long, delicious while, when they were both breathless and trembling slightly, Xu'er lifted her head. 

Her eyes were dazed, her lips even more swollen and red. 

She looked utterly consumed, and Su Mu knew her own expression must mirror it.

"Okay," Xu'er panted, a shaky laugh escaping her. 

"Okay, you win. A few more minutes here." She then nuzzled into Su Mu's neck, her voice a seductive whisper. 

"But Missy… as much as I love being right here… my legs are starting to get a little numb from this position, and my bed is so much more comfortable for…." She punctuated her words with a soft bite to Su Mu's shoulder that sent a jolt straight to her core. 

"And I really, really want to see what you're hiding under that very innocent top."

Su Mu shivered, a thrill running through her at the thought. 

The idea of Xu'er discovering the bustier, of what would follow in the privacy and comfort of the bedroom, finally outweighed her reluctance to move. 

"Alright," Su Mu conceded, her voice thick with anticipation. "Lead the way to your... laboratory, Professor Xu'er."

Xu'er chuckled, the sound of a warm puff of air against Su Mu's neck. 

"Delighted to, my eager student." She pressed one last, soft kiss to the spot she'd just nipped, then slowly, reluctantly, began to shift her weight off Su Mu's lap. 

Getting untangled was a delicious little struggle in itself. 

Xu'er didn't just hop off; she slid, her body brushing against Su Mu's in ways that sent fresh waves of heat through her. 

Her hand trailed from Su Mu's shoulder, down her arm, her fingers lightly dancing over Su Mu's own as she finally stood, her movements fluid and full of an easy grace that Su Mu couldn't help but admire.

"Come on then, my eager student," Xu'er said, holding out a hand, her eyes sparkling with mischief.

"Oh, I forgot to mention that, I prepared quite the curriculum planned for you, Missy." 

Su Mu let out a breath she hadn't realized she was holding as Xu'er stood, wiggling her legs a little.

Su Mu took Xu'er's offered hand, her palm tingling where their skin met. 

As Xu'er gently tugged, Su Mu rose from the sofa, her own legs feeling a little unsteady, partly from holding Xu'er and partly from the sheer force of anticipation coiling low in her belly. 

Xu'er didn't let go of her hand. 

Instead, she intertwined their fingers and began to lead Su Mu from the living area, down a short, dimly lit hallway. 

The apartment wasn't large, but every step, each movement drawn out and significant. 

The hallway was softly lit, a few framed pieces of art on the walls that Su Mu didn't quite register, her focus entirely on Xu'er's back as she led the way, and the warm, firm grip of her hand.

Su Mu watched the sway of Xu'er's hips as she walked ahead, the way her dark hair brushed against her shoulders. 

The simple sight was incredibly erotic, fueling the fire that was already burning brightly within Su Mu.

The silence between them now wasn't empty; it was filled with a crackling energy. 

The only sounds were their soft footsteps on the floor and the faint, almost inaudible thrum that Su Mu recognized as her Empathic Siphon, vibrating in tune with the heightened emotions in the air, amplifying every sensation, every subtle shift in Xu'er's energy, drawing them closer on a level beyond just the physical. 

It was like a magnetic pull, growing stronger as they neared the bedroom.

The short walk from the living room felt like a journey into a more intimate part of Xu'er's world. 

Xu'er paused at a doorway, turning back to look at Su Mu. 

Her expression was soft, almost vulnerable for a fleeting second, before that playful, confident heat returned to her eyes. 

She still held Su Mu's hand, her thumb gently stroking the back of it. 

She leaned in, her voice a low, husky whisper that caressed Su Mu's ear. "Ready for your next lesson, Missy?"

Su Mu's heart was pounding against her ribs like a trapped bird. She swallowed, her throat suddenly dry again despite all the wine. 

This was it. 

The air felt thick with anticipation, so potent Su Mu could almost taste it. 

She could only nod, words failing her as she looked into the depths of Xu'er's dark, knowing eyes.

Xu'er's lips curved into a slow, satisfied smile. 

"Good." With her free hand, she reached for the doorknob, turned it, and pushed the door open, revealing the soft, inviting glow of a bedroom beyond. 

"Welcome to my lab."

The bedroom wasn't what she might have expected. 

It wasn't overtly frilly or starkly modern. 

Instead, it was a haven of soft textures and warm, inviting colors. 

The walls were painted a deep, soothing indigo, almost like a twilight sky. 

The main source of light came from a couple of strategically placed lamps with amber shades, casting a golden, almost honey-like glow across the room, leaving intriguing shadows in the corners. 

A thick, plush rug that looked like a cloud of deep burgundy covered most of the wooden floor, muffling their footsteps. 

Heavy velvet curtains, the same deep indigo as the walls, were drawn across what Su Mu assumed was a large window, creating a cocoon-like sense of privacy and seclusion from the outside world. 

The air itself seemed to hum with a quiet energy, scented faintly with something exotic and sweet sandalwood and perhaps a hint of vanilla.

But the centerpiece, the undeniable heart of the room, was the bed.

It was huge, a magnificent expanse that looked big enough for three or four people to lounge comfortably. 

It was low to the ground, giving it a decadent, inviting feel. 

The headboard was a sweep of dark, carved wood, intricate but not fussy. 

And the bedding… oh, the bedding. 

It was a landscape of textures and rich jewel tones. 

Sheets that looked like dark silk, shimmering faintly in the lamplight, peeked out from under a thick, plush comforter that seemed to be made of crushed velvet in a shade of deep emerald green. 

Pillows of all shapes and sizes were scattered artfully.

Some large and square in the same emerald velvet, others smaller and round in contrasting shades of sapphire blue and amethyst purple, some with silken tassels, others with delicate embroidery. 

It looked like a bed designed for pleasure, for long, lazy mornings and even longer, passionate nights.

Su Mu found herself just staring for a moment, a little awestruck. "Xu'er," she breathed, "this room... It's beautiful. It's like you."

Xu'er squeezed her hand, a pleased smile on her lips. 

"I'm glad you like it, Missy. I wanted it to be a place where… well, you can feel comfortable, and not pressured…." 

She led Su Mu further into the room, towards a beautiful antique-looking dresser on one side. 

Next to it, on a small, ornate side table, was a delicately carved wooden box, about the size of a shoebox, its lid closed. 

There was also a sleek, modern music player, currently silent.

"Now," Xu'er said, her voice dropping to a conspiratorial whisper as she turned to face Su Mu, her hands coming up to rest on Su Mu's shoulders. 

Her gaze was intense, yet soft. "Before we get too comfortable on that bed… and believe me, we will."

"There's something I've been dying to share with you. Something I thought we might… experiment with together."
