After briefly considering my proposal, Chaerin nodded.
“Yeah. Help me. But how are you going to help? Do you have any gel?”
Chaerin asked in a small voice. I gestured for her to come closer, speaking casually.
“No, I don’t. Come closer.”
‘Crazy bastard. Seriously, I’m out of my mind.’
I smiled on the outside, but cursed myself inwardly.
It was only yesterday that, after seeing the ominous note, I had resolved to keep a low profile for a while.
And now I was planning to put my finger into my younger twin sister’s pussy in the middle of a classroom watched by more than twenty female university students and our homeroom teacher.
Reason screamed at me to stop, but instinct charged toward pleasure. And, as expected, instinct won.
Chaerin stood in front of me, fully exposing her lower body without even wearing underwear.
And just like that, the wariness and fear I had felt last night flew far away.
“Could you stick out your butt a little?”
Though Chaerin thought it strange, she obediently moved as I asked.
She immediately turned around and stuck her butt out toward me.

The sight before me was far more intense than the note.
Pale, round buttocks. Her private parts visible between them.
Her neatly groomed pussy, and above it, a small, tightly closed asshole.
That feminine rear view was enough to get my cock hard.
At first, the other women paid little attention to us as they inserted their devices.
But the moment I reached between Chaerin’s legs and touched her pussy, the classroom fell silent.
Dozens of heated gazes focused solely on the two of us.
Those gazes held not just curiosity but also envy, jealousy, and lust directed at Chaerin being touched by a man.
Chaerin, too, seemed conscious of those gazes and fell silent.
But the instant my finger touched her pussy, Chaerin’s body flinched, and I could feel all her nerves drawing toward my fingertip.
“Hey…! What are you doing?”
Chaerin cried out softly in embarrassment.
At her voice, the gazes in the classroom became even more blatant.
I could even feel Iseol noona’s gaze from where she stood in front of the lectern.
I spoke casually in a low voice, as if I wanted everyone to hear me.
“If you don’t have gel, you can just coat it with vaginal lubrication and put it in.”
At my words, I heard exclamations from various parts of the classroom, along with several girls swallowing hard.
Chaerin’s face turned bright red, and she couldn’t say a word.
From my seat, I made Chaerin spread her legs a little farther.
Chaerin obediently followed my request, spreading her thighs so I could touch her more easily.
It felt strange, as though she were a puppy naturally lifting its chin when its owner held out a hand.
“Why… in front of everyone….”
Chaerin grumbled, but she never pushed my hand away.
When my finger first touched her, Chaerin’s pussy felt slightly dry.
But as soon as I began gently stroking her labia with my finger, it quickly began to grow moist as if by magic.
After a few strokes, clear, transparent vaginal lubrication welled up from her pussy, making my finger slippery.
I slowly pushed one finger inside her pussy.
“Hngh….”
A thin moan escaped Chaerin’s lips. I moved only a little.
-Squelch
“Haaah….”
More vaginal lubrication flowed out, making a wet, squelching sound.
In the deathly quiet classroom, the sound and Chaerin’s lewd moans rang out unusually loudly.
Overwhelmed by the intense pleasure, Chaerin gripped the desk in front of her as though she wanted to hold on to anything.
Satisfied, I pulled my hand out and smeared the vaginal lubrication coating my fingers all over the smart Kegel device.
Then I pushed the device into Chaerin’s pussy.
The thin, slippery metal rod was smoothly sucked into Chaerin’s pussy.
“Hngh!”
Chaerin’s body flinched, and vaginal lubrication trickled from between her legs onto the floor.
Next, I brought the other device to Chaerin’s anus.
Because the opening was much narrower and more sensitive than her pussy, Chaerin’s body jerked even harder.
Once all the preparations were complete, Chaerin sat back down with her face flushed red.
I smiled in satisfaction and turned to Subin, who had been staring blankly at us.
“Subin, you didn’t bring any gel either?”
“Huh? Uh, yeah….”
Flustered, Subin unconsciously pushed the gel she had put in her bag a little deeper inside.
She glanced around once, then lowered her head shyly and spoke in a voice that barely carried.
“Um, me too… could you help me?”
I beckoned her over, as though I had been waiting for her to ask.
When Subin stuck out her butt, I deliberately teased her.
“Did watching Chaerin and me get you excited?”
During the physical examination and the photos for the female student IDs, Subin had seemed much less sensitive than the other women.
But now, perhaps because she was slightly aroused, the inside of her pussy was moist.
It seemed like plenty of vaginal lubrication would come out even without much touching.
Subin’s face turned red at my words. I began gently stroking her pussy with my finger.
It felt soft in a different way from Chaerin’s.
Subin flinched but stayed still, letting herself feel my touch.
When my finger entered her pussy, Subin’s thighs trembled faintly.
I caressed her while deliberately striking up a conversation.
“Subin, there’s something I want to ask you. Could you spare me some time after school?”
“Hah…? Mmm….”
“I want to hear more about the illness you mentioned before.”
When I pressed my finger firmly against her vaginal wall, Subin’s thighs trembled as she barely managed to answer.
“O-okay….”
In less than a minute, Subin’s pussy had grown slippery with vaginal lubrication too.
She seemed to feel even more strongly when I caressed her while talking to her.
I coated the devices with Subin’s vaginal lubrication and gently inserted them into her pussy and anus, respectively.
Subin also sat down and awkwardly squirmed with the devices inserted.
That was when it happened.
“Hey, class president!”
I turned at the lively voice and saw Yeji, a track-and-field athlete, smiling brightly at me.
She was a lively woman with slightly tanned, healthy skin, a firm figure, and a ponytail that suited her well. I remembered clearly that her thighs, in particular, were incredible.
“I didn’t bring any gel either. Could you help me?”
There was none of Subin’s shyness or Chaerin’s tsundere-like coyness in Yeji’s tone.
Rather, it carried a confidence that seemed to say, ‘I have no ulterior motives.’
I answered with a gentle smile.
“Of course. Come here.”
Yeji approached me without hesitation and stuck out her butt.
Her firm, toned buttocks, free of an ounce of flab thanks to her regular exercise, came into view.
Perhaps because of her copper-toned skin, her light pink pussy looked especially lewd.
When I reached between Yeji’s legs, she grinned and swayed her hips.
“Please take care of me, class president.”
Contrary to her cool demeanor, Yeji was incredibly sensitive.
The moment my finger touched her, her body shuddered with a breathy “Hngh!”
And, like Chaerin, she couldn’t last even thirty seconds before her vaginal lubrication came pouring out.
Her body was honest, and her reaction explosive.
I generously coated the Kegel devices with Yeji’s vaginal lubrication and slowly inserted them into her pussy and anus, respectively.
As I deliberately stroked her firm thighs gently in the process, Yeji let out a pleased nasal hum.
Could my actions have been the starting signal?
“M-me too!”
“Class president, help me too!”
Suddenly, girls all around the classroom began raising their hands and calling out to me.
They were all the female university students except Ayoung, the cold, aloof vice class president, and Hayeon, the eccentric who thought of herself as a man.
Every one of their eyes burned with the desire to be touched as well.
Savoring pussies of different shapes and textures, each reacting differently, was an utterly exhilarating experience.
One girl even cried, saying she was so happy that she had ended up in the same class as me.
Before I knew it, the classroom was filled with the women’s heated energy and the scent of vaginal lubrication.
Finally, after helping the last student, Iseol noona tried to begin the class.
But now that things had come this far, I had no intention of sparing her.
“Teacher.”
I called softly toward the lectern.
“Did you insert your device properly, teacher? If you had trouble, shall I put it in for you again?”
At my blatantly suggestive question, all the other women’s gazes turned toward Iseol noona.
She seemed flustered for a moment, but soon answered with a flushed face.
“…Yes. Please, class president.”
Forgetting even her position as a teacher, she answered like an obedient female.
Watching her, I thought to myself.
The government’s brainwashing education must certainly have played a major role in the belief in male superiority and female inferiority I had seen so far.
But beneath it all was powerful, uncontrollable female sexual desire.
That sexual desire, which made women crumble so easily at a single touch from a man, was intertwined with the brainwashing that taught male superiority and female inferiority.
Most women would be happy as long as a man penetrated their pussies, no matter what else he did.
