The Collapse of Absolute Rationality and the Switch in the Palm of Your Hand

"Ring ring—!!"

The sharp preparatory bell, like a scalpel, abruptly cut through the sensual yet viscous air in the office.

You jolted awake from the suffocating afterglow of pleasure, your heart still pounding in your chest. "Ms. Sayama," slumped over her desk, also jolted, like a cat whose tail had been stepped on. In her previously unfocused, even slightly rolled-back eyes, the rational light that once belonged to A-Jie was slowly and laboriously gathering again.

"Hoo...ha...damn...that ringtone scared the hell out of me..."

Although Ah Jie's voice was still heavy with panting, he had managed to regain his irritating tone. He awkwardly propped himself up, and with his movement, his two large breasts swayed heavily beneath his sweat-soaked shirt, creating a dazzling wave of flesh. The once well-tailored white shirt was now wrinkled beyond recognition, several buttons dangling precariously, and the collar wide open, revealing large expanses of snow-white skin covered in red marks.

The air was filled with the rich scent of heather, mixed with Mr. Sayama's signature citrus perfume, and that lingering, faint smell of biological leather—ironclad proof of your frenzied intercourse just now.

"Quick... help me button up my bra. This damn skin... is so sensitive, my hands are shaking so much I can't button it up myself."

Ah Jie turned around, cursing under his breath. His once smooth and delicate skin was now covered in the fragrant sweat from the muscle spasms during his orgasm. As you trembled, you fastened the clasp of his lace bra, your fingertips touching that still-hot skin.

Even after you've already ejaculated once, the feeling still sends shivers down your spine. The slightly trembling muscles under the skin, the clearly perceptible spine, and that invisible seam at the back of your neck that only you know... all of this reminds you that you just did more than just your homeroom teacher; you did it with your "good brother" in his "human skin."

The most exciting part was the part where they wore stockings.

Ah Jie sat in the chair, raised his long, beautiful leg, and pointed his toes. He picked up the black stockings that had been pulled down to his ankles and were now slightly sticky with bodily fluids, and skillfully gripped the garters with his thumbs.

"Sizzle—Sizzle—"

The sound of fingernails scraping against nylon fabric was exceptionally clear in the quiet office, carrying a strangely erotic connotation. The previously loose black stockings were gradually pulled upwards, like a layer of black paint, reappearing on that voluptuous body.

The curves of his calves were outlined, the shadows of his knees deepened, and finally, his thighs… those red handprints left by your rough kneading were now all sealed beneath the translucent black shadows. With a gentle flick at the base of his thighs, a soft "snap" sounded, and the absolute domain symbolizing taboo and temptation was re-formed.

Finally, he took out a lipstick from his bag, looked in the small mirror, and carefully applied it to his lips, which were slightly red and swollen from the passionate kiss and even had a few strands of saliva on them.

She pursed her lips, applied makeup, straightened her collar, and adjusted her glasses.

In just one minute, the wanton woman who was just beneath you, moaning and begging for pleasure with a dazed look in her eyes, was gone. In her place was the icy beauty who inspired both awe and lust in all the boys in the school—Misato Sayama.

Apart from the occasional lingering allure in those eyes, you could hardly find any flaws.

"Alright, let's go back to the classroom."

Just as you turned to open the door, Ah Jie suddenly called out to you.

"Wait, I almost forgot about this."

He pulled open the bottom drawer of his desk and, under the cover of a pile of lesson plans and red pens, took out a pink, oval-shaped object no bigger than a thumb, and a white wireless remote control.

Vibrating egg.

"Weren't you... still not satisfied?" A-Jie winked at you, a wicked smile creeping across his usually stern face as he licked his freshly applied red lips. "And this skin... seems to be getting a little craving it. Look—"

He didn't try to hide it from you; instead, he directly lifted the pencil skirt he had just straightened.

Between those beautiful legs in black stockings, the bare area, though covered by stockings, was still completely exposed and glistening.

"It's still flowing... This body's design is too lewd. As long as there's still a foreign sensation, I'll keep getting excited."

Before you could refuse, he spread his legs in front of you and pressed that little pink thing against your wet entrance.

"Pfft."

With a soft splash, the vibrator was instantly swallowed by the greedy soft flesh.

"Ugh...!"

A muffled groan escaped his lips, barely suppressed. A-Jie's brow furrowed, a blush instantly rising to his cheeks, and his body trembled violently. Clearly, that area was still extremely sensitive after being overstimulated, and even this minor intrusion of a foreign object brought a powerful stimulation.

"Give."

He placed the white remote control with the LCD screen into your palm, his fingertips lightly tracing the lines of your hand, leaving a warm, damp mark.

"This class is 'that' boring lesson on derivative applications. If I don't find something to have fun with... as the owner of this body, I'm going to fall asleep."

After saying that, he took a deep breath, like an actor putting on a mask, composed his expression, pushed open the door, and walked "tap tap tap" in his high heels towards the classroom at the other end of the corridor.

……

Back in the classroom, you sit in the back row by the window, your heart still pounding. The remote control in your palm is damp with sweat and has become slippery.

Not long after, the classroom door opened.

Misato Sayama walked in carrying a thick stack of exam papers. She still had that unapproachable air about her, with black-rimmed glasses perched on her high nose, a perfectly fitted white shirt, and a black stockings pencil skirt that accentuated her pear-shaped figure. Every step she took was steady and elegant.

"stand up."

The entire class stood up and bowed in unison.

As you look at "her" on the stage, an unprecedented sense of absurdity and immorality instantly overwhelms you. The students around you are all looking at her, their eyes filled with awe and the restlessness unique to adolescence.

But none of them knew that beneath this seemingly perfect goddess-like body lay the soul of a man—your good brother, A-Jie. They also didn't know that just ten minutes ago, this body was in the next office, frantically responding to your thrusts like a bitch. And now, she still contained what you had just personally handed her.

"Today we'll talk about the relationship between the monotonicity of a function and its derivative..."

Ms. Sayama's voice was clear and professional, and the chalk made a rhythmic "tap tap tap" sound on the blackboard. As she turned to write on the board, the firm curves of her hips were facing you.

You remembered the sensation of your palm striking that surface, the warmth beneath the black silk, and the little toy inside waiting for instructions…

Is this what it means to be a "dominant" person?

Looking at that extremely serious figure on the stage, you inexplicably reached into your desk and gently pressed your thumb on the remote control switch.

**Level 1: Micro-vibration.**

"...When the derivative is greater than zero, the function is... um..."

Mr. Sayama, who was on stage, suddenly paused for a moment.

The "hmm" was very soft, like an **** sigh. Her back trembled slightly for a moment, and her hand holding the chalk froze in mid-air for half a second. But it was only half a second. She quickly adjusted her posture and continued writing the formula, only her voice seemed slightly more tense than before, and her speaking speed unconsciously increased.

"Heh, he's quite tolerant," you chuckled to yourself. You knew that Ah Jie was using his willpower to fight against the body's instincts.

You pressed it again.

**Third setting: Pulse mode.**

The reaction was noticeably stronger this time.

As Mr. Sayama was explaining an example problem, his legs suddenly tightened involuntarily. It was an instinctive reaction to stimulation. His knees, encased in black stockings, pressed tightly together, rubbing against each other and making a very faint rustling sound.

"Students, look at the blackboard... the graph of this function... whew..."

She turned around and faced the whole class.

Her once fluent explanation began to become disjointed. One of her hands was on the podium, her knuckles turning slightly white from the ****.

The whole class was stunned, thinking the teacher was unwell.

"Teacher?" a girl in the front row asked, "Are you alright? Your face is so red."

Ms. Sayama took a deep breath but did not answer. You could see her shoulders trembling slightly, and the originally fair skin on her long neck was visibly flushing pink.

She looked up, her eyes behind her black-rimmed glasses fixed on you, sitting in the back corner.

His eyes were filled with anger, shame, and a deeply hidden...pleading look.

You know, right now, deep inside that layer of "skin" tightly encasing A-Jie's body, that little pink vibrating egg is frantically pounding against his sensitive spots. That pleasure, acting directly on his nerve endings, is slowly eroding his facade as a "teacher." The inner walls of his body are secreting love fluids like crazy; if he weren't wearing no underwear, his bodycon skirt would probably be soaked through.

But now, that slippery liquid is slowly flowing down the inside of her black stockings, running down her inner thighs.

That hot, sticky, and impossible-to-wipe feeling must have driven Ah Jie crazy, right?

You can almost hear Ah-Jie roaring at you in his mind: *“Fuck you! Stop it! It’s leaking! It’s really leaking onto my stockings!!”*

The feeling of controlling the goddess on the podium, the contrasting pleasure of manipulating "sacredness" and "depravity" at will, is simply irresistible.

You look at her beautiful, black-stockinged legs trembling violently under the lectern, and at her lower lip that she's biting down hard to hide her trembling, and a cruel smile curls at the corner of your mouth.

"This isn't enough, Mr. Sayama..."

You murmured softly, moving your thumb to the special red button.

**Maximum power: Random high-frequency vibration.**

"Click".

With that soft click of a key—

"ah--!!!"

A short, sharp cry shattered the silence of the classroom.

Ms. Sayama on the stage seemed to have been struck by an invisible lightning bolt. The chalk in her hand snapped with a "crack," and she lunged forward, slamming her hands heavily on the lectern with a loud bang.

"Splash—"

Lesson plans and test papers were scattered all over the floor on the lectern.

She couldn't stand up at all. Her once-proud long legs seemed to have lost their bones; her knees buckled, and she collapsed to her knees behind the podium.

"Teacher...?!"

The whole class stood up in a panic.

But no one dared to step forward. Through the gap in the podium, they could see their usually dignified and serious homeroom teacher kneeling on the ground, her body convulsing violently like a sieve. One hand gripped her skirt tightly, as if trying to hide something, while her thighs, encased in black stockings, were rubbing and clenching frantically.

"Ah...no...no...it's going to break..."

Although the sound was very soft, the students sitting in the front row could still vaguely hear the moaning that was both tearful and seductive to the bone.

You can see it clearly.

At the base of those black-stockinged thighs, a dark wet patch was spreading rapidly, gleaming lewdly under the fluorescent light.

Ah Jie completely broke down. This body named "Misato Sayama," under the gaze of dozens of pairs of eyes in the class and manipulated by the remote control in your hand, ushered in a **** and frenzied climax.

And you, looking at the trembling figure below the podium, gently put the remote control back in your pocket, revealing a satisfied smile.

This lesson has only just begun.
