Xu Er pressed one last, lingering kiss to her inner pussy before slowly, reluctantly, pulled back slowly, her lips still glistening, a satisfied, almost predatory smile playing on them. 

"We should get those drinks before I decide to keep you in here all night, Missy," she said, her voice husky.

Su Mu sagged against the sink, her legs feeling like overcooked noodles. A shaky sigh escaped her. 

"Don't take too long, Missy," Xu Er whispered, her eyes, dark and luminous, held a promise of more to come. 

She caressed Su Mu's cheek, her thumb brushing over swollen lips. 

"Those drinks are waiting... and so am I." With a final, smoldering look that sent a fresh shiver down Su Mu's spine, Xu Er slipped out of the steamy bathroom.

The click of the door closing sounded unnaturally loud in the sudden quiet. 

Su Mu let out a long, shaky breath, her body still humming with the aftershocks of her intense release. 

She looked at her reflection. Her silver hair was a mess, sticking to her damp forehead and neck. 

Her cheeks were flushed a deep rose, and her eyes, usually so composed, looked dazed and heavy-lidded. 

A small, almost shy smile touched her lips. "Wow," she breathed out, the word barely a whisper.

Her whole body felt wonderfully languid, every muscle loose and warm. 

The intensity of her own release had surprised her, a raw, untamed power she hadn't quite known she possessed. 

Her skin was sticky, and the scent of their mingled arousal hung heavy in the air, a potent reminder of what had just passed.

She pushed herself upright, her limbs feeling deliciously heavy. 

Looking down, she saw the evidence of their passion, her own wetness, a smear of something on the porcelain edge where Xu'er had leaned. 

A soft, pleased smile touched her lips, but first, she definitely needed to wash up. Again.

Turning back to the sink, Su Mu twisted the faucet, warm water gushing over her trembling hands. 

As she reached for the soap, her gaze fell on the mirror again. 

She could almost still see Xu'er there, her dark eyes alight with desire, her lips curved in that knowing smile. Su Mu touched her own lips, a soft, remembering gesture.

She reached for a soft washcloth, soaking it and then slowly, tenderly, began to wash herself. 

Every touch was a reminder. 

As she cleaned her inner thighs, she could almost still feel Xu Er's mouth, her clever tongue. 

A fresh wave of heat bloomed low in her belly at the memory, a gentle echo of the earlier inferno. 

Her own scent, mingled with Xu Er's, rose with the steam from the cloth, a musky, sweet, and undeniably arousing.

She took her time, the simple act of cleansing feeling almost ritualistic. 

Her body felt exquisitely sensitized, every nerve ending alive and tingling. 

She glanced at her reflection. 

Her eyes were bright, pupils still slightly dilated, her lips plump and red. 

A faint flush still graced her cheeks and chest. 

She looked… thoroughly debauched. And wonderfully alive.

The thought of Xu Er waiting for more sent a thrill of anticipation through her. 

This was just an intermission, a chance to catch their breath before the next act. 

Drying herself with a fluffy towel, Su Mu felt a newfound energy beginning to replace the languor. 

A soft sigh escaped Su Mu as she padded, still naked, from the steamy bathroom into the relative cool of the bedroom. 

Her skin felt clean and hypersensitive, every brush of air a faint caress. 

The air here was cooler, carrying the faint, lingering scent of whatever incense Xu Er sometimes burned, together with the lingering scent of their intimacy, seemed to follow her, like a ghostly perfume.

Su Mu soon wrapped a soft towel around her body, the terry cloth a comforting weight against her still-sensitive skin.

She went to the small wardrobe. 

'What to wear?' Part of her wanted to slip into something overly seductive, but another, perhaps wiser part, knew that the real seduction was already well underway, woven into every glance and touch they'd shared. 

Her gaze fell upon the shopping bags from earlier, and a small, knowing smile played on her lips. 

Xu Er had been so insistent, her eyes sparkling with mischief when she'd held up that particular item. 

Reaching into the tissue paper, Su Mu pulled out the bustier. 

It was even more exquisite than she remembered from the shop, black lace over deep crimson silk, delicate straps.

Holding it against herself, she considered. 'This was… bold.' But then again, everything about Xu Er and what had just happened between them was bold and exhilarating.

The faint, ever-present hum of her Empathic Siphon seemed to agree, buzzing with a low, anticipatory thrum. 

She slipped the bustier on. The silk was cool against her warm skin; it fastened in the front, and as she hooked each clasp, she felt a shiver of excitement. 

It pushed her breasts up, framing them beautifully, and cinched her waist just enough to accentuate her curves. 

She paired it with a simple pair of black silk tap pants they'd also picked out, feeling both wickedly daring and surprisingly confident.

Her silver hair was still slightly damp at the roots, curling softly around her face. She ran her fingers through it, fluffing it a little, deciding against any complicated styling. 

Her makeup had mostly survived the steam and the passion, but she reapplied a touch of kohl to her eyes, making them seem deeper and more mysterious, and a sheer berry tint to her lips, already swollen and sensitive from Xu'er's kisses.

To cover her delightful secret, she chose one of the simpler outfits they'd also acquired, a soft, deep blue tunic dress made of a flowing material that would drape elegantly and feel good against her skin, but wouldn't hint at what's hidden beneath. 

It was comfortable, unassuming, and perfect.

Moving back to the sink, Su Mu examined her face. Her earlier exertions had left a natural flush that no makeup could truly replicate.

There was a new softness around her mouth, a vulnerability she wasn't used to seeing.

As she did, her mind replayed the scene in the bathroom making Xu er cum, and then the complete, shattering embarrassment of her own release. 

It was different from anything she'd felt so far. 

But what surprised Su Mu more was how good she had felt giving pleasure, how intoxicating it had been to witness Xu Er cum. 

It was a powerful feeling, this give and take, this shared vulnerability and escalating desire. A connection was forming between them, deeper and more potent than just physical.

She took one last look in the mirror. The simple clothes hid the secret invitation of the bustier beneath. 

Her eyes were bright, her expression a mix of contentment and eager anticipation. She felt good. Really good.

As Su Mu stepped out of the bathroom, the air in the house felt a little cooler, the lingering steam from her ablutions already starting to fade. 

The soft lamplight in the living area cast warm shadows, making the space feel cozy and private.

She peeked into the main room. And there she was.

Xu Er was standing by the small minibar setup near the window, her back mostly to Su Mu. 

She was wearing a silky robe that shimmered slightly in the soft lamplight, the dark color a stark contrast to her pale skin. 

It was loosely tied, hinting at the curves beneath. 

One hand was resting on her hip, the other idly swirling the contents of a glass, an amber liquid catching the light. 

Even from the back, her posture exuded a relaxed confidence, a patient waiting.

As if sensing Su Mu's presence, Xu Er slowly turned. 

Her eyes met Su Mu's across the room, and a slow, knowing smile spread across her face. 

It was a smile that promised heat, promised fun, promised all the things Su Mu was now eagerly awaiting.

"There you are, Missy," Xu'er's voice was a low purr, smooth and inviting, like the drink in her hand. 

She lifted her glass a little, a silent invitation. "I was beginning to think you'd gotten lost in there."

Su Mu felt a blush creep up her neck, but she met Xu'er's gaze boldly. She walked towards Xu'er, each step feeling deliberate, closing the distance between them. 

They settled onto the sofa, not too close, but not too far apart either. 

An invisible current seemed to flow between them in the space. 

Su Mu watched Xu Er as she talked about something trivial, but all Su Mu could focus on was the way Xu'er's lips moved, the expressive gestures of her hands, and the way her eyes kept finding Su Mu's, holding her gaze for a moment before looking away.

The drinks were just a prelude, a pleasant pause in their unfolding story. 

Su Mu felt a growing certainty that whatever happened next, it would be even more intense, more revealing than what they had already shared. 

And she couldn't wait...
