Each insertion aimed to penetrate deeper, and each withdrawal brought forth more thick, warm love fluid. Her body trembled violently under my fingers, her thigh muscles spasming and relaxing.
"Then…" Mom's voice trembled violently, becoming hoarse and uncontrollable, as if she were struggling to continue explaining, "After the system was released… the spring retracted… driving the block to move… initially, the spring's extension was still large… the retraction force was large… at the same time… the friction was kinetic friction…"
"Then... what about the direction of acceleration, Professor Zhou?" Li Ming asked.
"A…A is pulled to the right by the spring…and the kinetic friction moves to the left…" Mom explained intermittently, her waist seemed to sway slightly, responding to my fingers, or perhaps trying to avoid that deadly stimulation.
His voice trembled more and more, and his nasal tone became heavier and heavier. He had to take a breath every few words.
Li Ming's voice was full of confusion: "Teacher Zhou, are you... are you alright? Your face is so red, and your voice is... do you have a cold? Should we go to the infirmary?"
"No! No need!... Cough, it's... it's a bit hot..." Mom almost blurted out, her voice hurried, "The air conditioner, the air conditioner might not be set low enough... I, I'm fine!"
She cleared her throat again, her voice strained as if on the verge of collapse, "You...you listen carefully! For A...at the beginning, the spring tension is high...so...the net external force is to the right...it accelerates to the right..."
"What about B..."
Just as Li Ming was about to ask again, I suddenly increased the pressure of my two fingers, scraping across a dense patch of sensitive flesh folds deep inside her wet and hot cavity, and then forcefully bending them up to press against the soft indentation at the deepest part!
"Ah ...
A sharp, short groan, completely out of control and filled with extreme pleasure and collapse, finally broke through the blockage in her throat and suddenly echoed throughout the office!
Then came a deathly silence, broken only by the monotonous hum of the air conditioner.
I can imagine the astonishment on Li Ming's face right now.
On the table, I heard the frantic rustling of pages from books.
The mother's chair slid backward suddenly, and she collapsed onto the table as if all her strength had been drained, her arms covering her face, her body still heaving uncontrollably.
"Teacher Zhou... Teacher Zhou! What's wrong?! Are you really alright?" Li Ming's voice was clearly panicked.
Several seconds later, a muffled, broken voice, thick with nasal tone and even a hint of sob, finally came from under the mother's elbow: "It's... nothing... just an old problem... my stomach... my stomach is cramping a bit... it hurts... but it'll be over soon..."
She took a deep breath, her voice trembling, "You...you should go eat...this question...can be asked again this afternoon..." The weakness and panic in her tone were undeniable.
"...Oh...okay! Take care of yourself, Teacher Zhou!" Li Ming was startled by this, quickly responded, and hurriedly left the office, closing the door with a "bang".
The office fell silent again, with only the low hum of the air conditioner and the increasingly clear, uncontrollable heavy breathing and sobbing of the mother.
I then slowly crawled out from under the table.
Mom was still slumped over the table, her shoulders twitching slightly, and her exposed earlobes were so red they looked like they were about to bleed.
I licked my index and middle fingers, which were covered in her warm, slippery love juice that smelled sweet and fishy, and walked over to her, grinning mischievously as I held my two shiny fingers to her lips.
"Look, what did you vomit from your 'stomach'?"
Mom suddenly raised her head, her face covered in tears and sweat, her eyes red from crying, and her hair disheveled and plastered to her forehead.
She glared at me fiercely, her eyes filled with both shame and anger, as if she wanted to devour me alive.
But the next second, she bit her lower lip, which was a little red and swollen from the kiss, and with a complex and indescribable sense of resignation and indulgence, she actually opened her mouth slightly.
A soft, supple tongue emerged, with an inexplicable reverence and submissiveness, slowly and carefully licking my two sticky fingers.
The scraping of her tongue brought a tingling, itchy sensation, and she swept away every last drop of the liquid mixed with love juice and subtle desire that remained on it.
After swallowing, the reproachful look in her eyes hadn't completely faded, but she softly uttered a few words:
"You little rascal, are you satisfied now?"
Seeing my mother slumped over her desk, looking both ashamed and angry, with tears still glistening in the corners of her eyes, and hearing her reproachful "You little rascal, are you satisfied now?", I grinned, deliberately straightened my back, pointed to the bulging crotch of my school trousers, and said in a low voice with a mischievous swagger, "Me? I'm comfortable, but it... hasn't nodded yet."
He lightly pointed to the spot where the tent was set up.
My mother looked up and glanced in the direction I was pointing, her cheeks instantly flushing red to the tips of her ears.
She rolled her eyes at me, her gaze a mixture of embarrassment and indulgent "I just can't do anything with you."
She took a deep breath and reached out her hand.
Cool fingertips brushed aside the elastic band of my school pants and slipped inside. With a slightly annoyed force, they pulled out my huge, throbbing, and frighteningly hot thing that had been pent up for so long!
Freed from the constraints of the fabric, it practically bounced upright in front of the desk, its purplish-red glans glistening with oil, arrogant and eager.
Without another word, she parted her red lips slightly, lowered her head, and took the swollen, hot glans into her mouth.
The warm, moist mouth instantly enveloped me, and the familiar tightness and skillful licking of the tongue sent a shiver down my spine.
"Uh..." I couldn't help but groan, my hand resting on the edge of the table as I felt her lips and tongue working so hard to serve me.
But today, I don't know what's wrong. Maybe the "foreplay" under the table was too intense, or maybe the "secret of the vacuum" is still burning my nerves. That deadly pleasure feels like it's through a thick membrane, making my heart itch, but I can never reach the peak.
She was down there swallowing and spitting for a while, her cheeks were sore, but I held back and didn't ejaculate.
"Hmm...uh?" She finally stopped, a trace of saliva still clinging to the corner of her mouth. She looked up at me, puzzled, her brows furrowed, her breath coming in a slightly annoyed gasp: "...Why...why haven't you ejaculated yet? My little darling...are you made of iron today? Are you trying to wear your mother down?"
Looking at her rosy, slightly swollen lips and hazy eyes, my lust intensified.
He didn't say a word, but his eyes, like little hooks, kept glancing between her long legs covered in flesh-colored stockings beneath her black skirt.
Following my gaze, Mom looked down at herself and instantly understood what I meant.
The last trace of color drained from her face in an instant, and her lips trembled slightly: "You...you're crazy? In broad daylight...in the office...no! Absolutely not!" She spoke with unwavering resolve, her voice trembling with terror.
I raised an eyebrow, not urging her, and just looked at her with amusement, deliberately flexing my erect weapon.
Time seemed to stretch out, and all that remained in the office was the hum of the air conditioner and our heavy breathing.
Her eyes darted back and forth between my gaze and the weapon beneath her, a fierce struggle in them.
There was shame and fear in it, but deeper still, a long-suppressed and aroused flame was stirring.
Sweat trickled down her temples and dripped onto the table.
"Sigh..." A barely audible sigh, filled with despair, escaped from her lips.
She suddenly stood up, her face showing a resolute determination, and strode to the window. With a "whoosh—!", she forcefully pulled the curtains shut!
The glaring sunlight was blocked out, and the office instantly became several degrees darker, with ambiguous lighting.
Immediately afterwards, she turned and walked to the door, "click," and locked the door from the inside!
The final safety valve has been activated.
After locking the door, she took a deep breath, turned around, and walked back to her desk without further hesitation.
He slammed his hands on the heavy tabletop, his upper body obediently bending down and lowering his waist.
Her plump buttocks, encased in a tight black pencil skirt, instantly rose high and alluringly, forming a perfectly lewd curve.
Then, she turned her head to the side and glanced at me sideways.
On that face, flushed with a peach-like blush, there was no trace of the shock and shame from before.
All that's left is blatant seduction and a resigned, utterly unrestrained, and flamboyant attitude.
Her red lips parted slightly, revealing a languid yet provocative smile; her voice was both alluring and sweet, like melting honey.
"What are you still standing there for?... You little rascal... Come on. Today... I'm truly defeated by you."
That "you little rascal" made my bones melt!
I took two steps to get behind her and lifted up her annoying skirt with one hand!
His fingertips immediately touched the bare, smooth, warm flesh of her buttocks above the edge of the stockings, and then he unceremoniously probed into the valley between her legs!
What my fingertips touched was not the obstruction of the fabric, but two fleshy petals that were already wet, muddy, swollen and full!
"Tsk!" I deliberately smacked my lips, my fingertips smeared with the sticky, warm fluid, and sniffed it. Then, with a wicked grin, I roughly scraped her sensitive clitoris, whispering into her raised buttocks, my voice hoarse and amused: "Teacher Zhou... you haven't even finished your 'class' yet, and down there... why is it 'raining' on its own? Hmm? It's soaking wet like a waterfall... could it be... that you were thinking about this while looking at me from below the podium during class? Hmm?"
