"My, my, such enthusiasm," she purred. "But now, it's my turn to offer a special kind of delight." With a smooth, deliberate movement, she reached for something Su Mu couldn't quite see at first. 

Then, Su Mu gasped quietly as she realized what it was – Xu'er produced the realistic-looking strap-on dildo that Su Mu had seen in the changing room. 

The same "secret weapon" that she tried to use it on her.

In a surprisingly bold move, Xu'er quickly and skillfully put on the strap-on. 

The two women, who had been caught up in their own pleasure, watched with wide, curious eyes, a new spark of excitement on their faces. 

Xu'er, now wearing the strap-on, turned her attention to one of the women, who lay back on the couch, her expression a mix of anticipation and eagerness. 

"Are you ready for something a little more... fulfilling, my loves?" Xu'er teased, giving them a wicked wink. 

"God, yes, Xu'er! Please!" the brunette panted, her gaze locked on the gleaming toy. 

"I need it now!" 

Xu'er positioned herself above the brunette, who lay back against the plush cushions, her legs eagerly parted. 

With a slow, deliberate, and powerful thrust, Xu'er entered her. 

The brunette screamed, a sound that was half shock, half ecstasy.

Xu'er used the strap-on with impressive skill, her hips moving in a steady, rhythmic way. 

With each thrust, she seemed to increase her force just a little, making the woman beneath her gasp and moan louder, her body arching in pleasure.

"Deeper, Xu'er! Oh, yes, harder! Don't stop!" she begged, her hips bucking up to meet each thrust.

Young Master Zhao leaned forward slightly, his eyes glittering as he watched the passionate display.

While Xu'er was busy making sure one of the women was having an incredibly good time, the second woman, who had been watching the scene with fascination, slowly turned her attention away from them. 

She shifted her gaze, her eyes now fixed on Young Master Zhao, who was still sitting on the couch a little way off, watching everything unfold with that look of a king enjoying his private entertainment. 

The redhead, her bunny ears flopping playfully with each movement, crawled slowly and seductively across the plush carpet towards Young Master Zhao. 

Her eyes, still bright with arousal from watching Xu'er and the brunette, were now fixed on him. 

She stopped just before him, looking up with a coy smile.

"Master, did you enjoy the show?" she purred, her voice husky. 

"Or are you perhaps feeling a little left out?" She reached out a tentative hand, lightly touching his knee over the expensive silk of his robe.

Young Master Zhao chuckled, a low, satisfied sound. 

He leaned back, steepling his fingers. "The show was... not bad, my dear." He placed his hand over hers on his knee. "What did you have in mind?"

"Oh, I have a few ideas," the redhead whispered, her gaze dropping meaningfully to his lap before flicking back up to his eyes. 

"Or perhaps you have some preferences you'd like to share with me?" She leaned closer, her warm breath ghosting over his skin.

Meanwhile, Xu'er paid no mind to Young Master Zhao and the redhead. 

True to the store's policy—or perhaps her own professional focus—her attention was solely on the brunette beneath her. 

She continued her powerful, rhythmic thrusts with the strap-on. "That's it, baby," Xu'er murmured, her voice low and encouraging against the brunette's ear. "Let go... feel it all. You're so close."

The brunette was lost in sensation, her moans growing louder, her fingers digging into the sofa cushions. 

"Oh, Xu'er! Yes! Yes! I can't... I'm going to..." Her body arched sharply, a keening cry tearing from her throat as waves of pleasure washed over her. 

She shuddered violently, her legs trembling around Xu'er.

Xu'er held her close, continuing with a few more slow, deep thrusts as the brunette's orgasm subsided into soft whimpers and gasps. 

"There now," Xu'er whispered soothingly, gently withdrawing. "Wasn't that wonderful?"

The brunette nodded weakly, her eyes still glazed over. "Amazing..." she breathed.

Xu'er gave her a tender kiss on the forehead. "You rest for a moment, sweet thing."

As the brunette lay there, catching her breath, her gaze drifted over to where the redhead was now very intimately engaged with Young Master Zhao. 

The redhead was kneeling before him, her head bowed in his lap, her hands busy under his robe. 

Young Master Zhao had his eyes closed, a look of intense pleasure on his face, his fingers tangled in the redhead's hair.

A new spark lit in the brunette's eyes. 

Perhaps it was the lingering arousal, or maybe seeing her companion with the Young Master ignited a fresh wave of desire. 

Slowly, gracefully, she pushed herself up from the couch. Her half-bunny outfit was delightfully revealing, tantalizing glimpses of her still-flushed skin.

Xu'er watched her with a knowing smile but made no move to join or direct. 

Her role was with the women, and she herself didn't like men that much. 

She leaned back against the cushions, allowing the dynamic in the room to shift naturally.

Su Mu's gaze outside flickered towards the small monitor that showed discreet views of the private lounges. 

For just a second, she caught a glimpse of the scene unfolding in Young Master Zhao's room – tangled limbs, the bunny girl outfits now mostly discarded, and movements that left little to the imagination.

Her eyes widened slightly. She immediately understood the very explicit nature of what was happening. 

A little flush crept up her neck, and concerned that watching any longer might fill her head with thoughts she didn't want or need, especially at work, Su Mu quickly reached out and closed that particular viewing window on her screen. 

"Nope, not going to watch that," she muttered quietly to herself, shaking her head a little.

With no customers currently in RomantiX, the store was quiet and calm. 

Su Mu decided to use the downtime productively. 

She closed her eyes and focused on the, intricate runes she had been so focused on the night before to craft her Will Rune, a key component for her evoulation.

Thanks to her steady efforts and the fact that she was becoming more familiar and comfortable with the delicate art of rune construction, she had actually managed to complete a large part of it. 

Looking at it now, she estimated that only about 30 to 40 percent of the complex patterns and energy lines were left to finish. 

Once done, the Will Rune would fulfill a crucial requirement set out in the Lunar Disc Breathing Method, the spiritual cultivation technique she was diligently practicing. 

Focusing on the precise, almost meditative work was a welcome distraction and a much better use of her mental energy.

To her surprise, when Su Mu inspected her Spiritual Realm, she found that the incomplete Will Rune remained unchanged.

However, when she shifted her focus to her attribute panel, she noticed something different. 

The progress bar, which was at 73.8% when she checked it first thing in the morning, now displayed a much higher number: 86.3%. 

And as she watched, the number continued to tick upwards, slowly but steadily, adding a tiny fraction more with each passing moment.

"Hmm?" Su Mu thought, a slight frown creasing her brow as she mentally double-checked the figures.

 "Why has the progress bar jumped up so much? It was definitely only at about 73.8% when I looked this morning."

She tried to reason it out. 

"Okay, so comparing it to yesterday... I gained 0.8% overnight, and I figured that was from my body just naturally absorbing the ambient spiritual energy in the air while I slept."

"That makes sense." She did a quick mental calculation. "If it was 0.8% for the whole night, say over about eight hours, that's an average of 0.1% every hour."

Her frown deepened. 

"But now," she observed, watching the panel intently, "the progress is accelerating like crazy. It's increasing by what looks like 0.1% almost every minute!" 

She watched for another minute, and sure enough, the number ticked up by another tenth of a percent. 

This was a dramatic and completely unusual shift in the rate of her spiritual energy absorption and progress. 

Something was definitely different.
