Seeing Yu Xiaogang turn away again, ignoring him, Tang Yin smirked and glanced down at Liu Erlong, who was bent over beneath the desk.
At this moment, Liu Erlong's posture was incredibly alluring.
She was still sitting on Tang Yin's lap, their lower bodies tightly connected, while her upper body was bent forward, hidden beneath the desk. This caused her backside to arch high in the air, appearing exceptionally round and full.
The sight of this tantalizing position made Tang Yin unable to resist reaching out to savor the smooth, soft sensation beneath his fingers.
Then, without warning, he raised his hand and brought it down sharply—
Smack!
A crisp sound echoed through the room.
Since he had already warned Yu Xiaogang that there might be some noise that could disturb his reading, Tang Yin didn't hold back at all, striking Liu Erlong's plump rear with full force.
"Ah—it hurts!"
Liu Erlong, who had been bowing her head close to the ground, suddenly felt a fiery sting spread through her body, and she couldn't help but let out a soft moan.
Tang Yin's strike had been painful.
But… why did it also feel strangely pleasurable?
Do I… have some kind of masochistic tendency?
No…
That can't be.
It's just… just a little bit of pleasure. That's normal.
Yes.
Definitely.
Her face burning with embarrassment, Liu Erlong stared at the floor, trying to convince herself.
Tang Yin glanced at the red handprint now imprinted on her round backside and grinned wickedly. He rubbed the spot firmly, making Liu Erlong feel a different kind of sensation—distinct from the sharp sting.
On the sofa, Yu Xiaogang furrowed his brows.
The loud noise Tang Yin had made had disrupted his reading. He wanted to turn around and say something, but remembering Tang Yin's earlier warning, he held back.
Smack!
A moment later, Yu Xiaogang's frown deepened.
The strange sound had returned—even louder than before.
Forget it, I'll just focus on my book. Once Teacher A Yin arrives and I ask my questions, I'll leave.
Suppressing his irritation, Yu Xiaogang tried to ignore the noises.
Smack!
But then—
The sounds grew louder and more frequent.
Yu Xiaogang, who already held little fondness for Tang Yin, felt a surge of anger but still said nothing.
However, the relentless disturbances made it nearly impossible for him to concentrate.
Finally, he turned around, wanting to see what exactly Tang Yin was doing.
But what he saw only confused him further.
Tang Yin's movements were erratic—sometimes shifting his hands, sometimes his lower body—but Yu Xiaogang couldn't make sense of it.
Noticing Yu Xiaogang's gaze, Tang Yin paused his stimulation of Liu Erlong and offered a perfunctory explanation:
"Ah, Grandmaster, my apologies. I was just slapping my thigh to relax the muscles. You know how intense my training is—it causes strain, so a little percussive therapy is necessary."
"Mn, proper massage is indeed important for recovery," Yu Xiaogang replied stiffly before turning back to his book.
Meanwhile, beneath the desk, Liu Erlong's face was flushed with desire.
She needed more—needed Tang Yin to push her further, to send her into ecstasy.
As for Yu Xiaogang?
After the shameful words she had spoken earlier, he had completely vanished from her mind. Now, there was only Tang Yin.
If not for the fear of being discovered, she would have screamed—
"Faster! Make me lose myself!"
Tang Yin sensed her desperation. Hidden beneath the desk, he wasn't worried about being caught—only that Liu Erlong might overflow if this continued.
Smack!
Seeing Liu Erlong's pleading gaze, Tang Yin knew she craved more. Without hesitation, he delivered another sharp slap.
Then, like a Gatling gun unleashing its barrage, he opened fire relentlessly.
"Nngh…!"
After what felt like an eternity, Liu Erlong trembled, a choked sob escaping her lips.
Her body convulsed violently, no longer under her control.
A terrifying tidal wave surged from the abyssal depths, bursting forth like a collapsing dam—unstoppable, uncontrollable.
At the same time, Tang Yin unloaded his ammunition directly into the floodgates of Liu Erlong's overflowing reservoir.
Their simultaneous eruptions collided, sending shockwaves of pleasure through both of them—wave after wave of bliss.
"Huh? Why does my scalp feel… strange?"
On the sofa, Yu Xiaogang rubbed his head, an odd numbness spreading over him.
Then, an inexplicable sorrow gripped his heart—as if someone important had just left him.
The suffocating ache made it impossible to focus.
Forget it. I'll come back tomorrow.
Without a word to Tang Yin, Yu Xiaogang stood and left the office.
Tang Yin, wholly absorbed in Liu Erlong—the woman who brought him such pleasure—didn't even notice Yu Xiaogang's departure.
"Haah…"
Leaning back in his chair, Tang Yin exhaled deeply, satisfied. He patted Liu Erlong's round backside, signaling her to rise.
Now aware that Yu Xiaogang was gone, Liu Erlong had regained some composure.
But instead of pulling away, she shocked Tang Yin by suddenly grabbing his head and kissing him fiercely.
Her long, shapely legs straddled him as she positioned herself over his Gatling gun and plunged down.
"Nngh…!"
A low, pleasured moan escaped her lips as she deepened the kiss.
"Erlong, your initiative surprises me," Tang Yin murmured against her lips. "But I like this side of you. From now on, you belong to me."
"Yes… I'm yours. Only yours," Liu Erlong gasped, begging for more.
And so, in A Yin's office, the two engaged in a fierce battle—kissing, grinding, clashing with abandon.
Meanwhile, not long after Yu Xiaogang left, A Yin herself approached the office.
She planned to fetch her adopted son, Tang Yin, so they could return home for dinner—and then retire to their room for bedtime.
And bedtime, of course, meant shedding every last stitch of clothing.
