36th Rule, Devoted Fingering for Marin in Heat During Lecture
♥Marin♥
Such a thing... had never happened even once.
The major professor's passionate lecture didn't register a single word.
Just attending class with my puppy, and yet...
My heart pounded like mad.
A distressing situation I'd never experienced in my life.
Even after last night, when my pelvis felt crushed from having my legs pinned down so hard.
My body was fiercely craving the cock of the puppy right beside me.
I desperately wanted him to torment me until I lost my mind, just like yesterday.
To hug me so tight my body shattered.
Maybe because of that, blood rushed downward.
Uncontrollable hot fluids gushed out in waves.
Fearing my skirt would get soaked, I hurriedly lifted it.
Sure enough, the floor beneath the chair was already drenched in my juices.
In that mortifying panic, gripping my pen and bowing my head low—
Thud.
The puppy grabbed tissues from my bag and started plugging my twitching pussy.
"Hngh♡!"
Right in the middle of the lecture hall, where the professor's voice droned on.
The rough texture of the tissue brushed my hypersensitive skin, and I couldn't help but twitch my hips, letting out a moan.
The professor, lost in his lecture, didn't notice.
But every student around us turned to stare.
Even as I clamped my hand over my mouth, waves of shame crashed over me, setting my face and my core ablaze.
My juices surged even fiercer, soaking the tissues through.
Each time, the puppy pulled out a fresh one and pressed it to my pussy lips.
So soft.
His gentle touch stroking my sensitive folds sent electric shivers racing up my spine from sheer arousal.
That addictive caress kept drawing my body toward him.
Before I knew it, I'd scooted closer until I was plastered against him.
Then I glanced at the clock.
Still about thirty minutes until the lecture ended.
For now, the puppy's tissues were a temporary fix.
......But something was missing.
My dopamine system, already wrecked beyond repair, refused to be satisfied with mere tissues—it craved a far more intense reward.
Just pressing the tissues against my pussy lips wasn't enough.
So I seized his big, rough thumb, which was trying to wipe away my juices.
Taking a deep breath to steel myself.
Shaking off the humiliation flooding me as best I could.
Gathering every ounce of courage, I begged him.
"......Honey. This precious part of mine that won't stop throbbing... calm it with your finger, honey."

★Toilet★
Marin's eyes glistened more moistly than ever, her face on the verge of tears.
I was flustered.
It was the first time she'd ever made an expression like that.
A moment ago, when she'd moaned, everyone had stared our way.
Now they were all focused on the lecture again.
So I cautiously shook my head at her, mouthing no.
"B-but... it itches here so bad I can't stand it anymore...... So please, I beg you. Scratch it quick and make me comfortable......"
Her whispered voice trembled. Her ass twitched.
Those lewd words set my own heart racing.
I knew I shouldn't in my head, but I found myself glancing around anyway.
Luckily, the students' eyes were forward again. The back row was our perfect blind spot.
There was no real reason to refuse Marin's demand for sex during class.
Swept away by her plea, I carefully extended my hand and cleared away the soaked tissue clumps.
Then, between her spread thighs, I pressed my index finger to that scorching, aroused spot.
Squish.
"Hahk......♡!"
Marin clamped her hand over her mouth, swallowing the moan.
Just a touch, and her pelvis jerked wildly.
Her pussy lips heaved like they were coughing up juices, the air filling with her hot mint scent.
The person a seat away sniffed—each time, my heart shrank in terror.
I swallowed hard, fearing we'd be caught, but the thrill of fingering her during class made me stroke her folds... then plunge my middle finger deep inside.
Squelch♡.
Her soft pussy flesh clung to every knuckle, burning hot.
Scorching heat. Juices flooded my hand without respite.
As she'd begged, I curled my finger to scratch the itch, gouging roughly into that tight crevice.
Squish♡, squish♡.
A faint lewd sound tickled my ears. Nearby students caught it, glancing around at the squelching.
Marin stared fixedly at her textbook, but her mind was gone—she panted hot breaths into my ear.
In the middle of a lecture hall with 150 gazes forward, I was violating the girl everyone admired, Marin.
Each twitch sent a fishy-sweet aroma wafting under the desk.
To avoid detection, I madly scribbled meaningless lines with my left hand, pretending to take notes.
Marin bit her lip to stifle her moans, her contractions gripping my finger tighter, more brazenly.
As I eased my finger deeper to soothe her pussy—
Tok, roll roll.
A pen dropped from the seat right next to us.
The smooth, rounded barrel hit the floor and rolled straight toward me.
Glance around.
Its owner ducked down to search for it.
It was only a matter of time before his eyes hit under the desk—my right arm buried between Marin's thighs.
Ah, no! If we're caught now, it's over.
I froze, my hand still deep inside her.
But Marin? She was different.
"Hah, eung......"
This peril only spurred her on—her pussy walls clamped my finger harder.
She pressed her ass back to trap my hand, grabbing my wrist through her skirt hem with all her strength.
Thud.
The guy's hand touched the floor. Just a bit lower, and he'd see my drenched hand and her disheveled skirt.
In desperation, I kicked the pen with my left foot, sending it toward him.
"Eh? Oh."
It rolled to his feet. Luckily, he stopped short of bending fully.
"Thanks~."
He picked it up and straightened, but he sniffed the air, his face twisting oddly as he turned toward us.
He tilted his head, eyeing me and Marin back and forth. My heart nearly stopped.
But then—
"Okay, focus. Now, I'll explain the assignment due before the next lecture."
Perfect timing.
The professor pulled everyone's attention forward again.
Marin and I locked eyes. What we felt wasn't mere relief at dodging disaster.
United by my finger and her pussy, it was an intense catharsis we'd never feel in normal circumstances.
Captive to the pleasure of depravity, Marin gushed thicker juices, and I crushed her walls harder.
That let me pinpoint her weak spot instantly.
No rationality left in Marin's eyes—just instinctual bliss, ragged breaths.
Fear transmuted to lust; her depths burned hotter than before, pulsing as they swallowed my finger.
Staring at her textbook, Marin murmured low.
'Feels good...... scratch harder.'
As if others' stares meant nothing, she rocked her hips fiercer.
Mint-scented juices sloshed under the desk.
With trembling fingers, I plunged to her deepest core, pressing my pen to my notebook to mask the lewd sounds with fake notes.
Luckily, the room buzzed with chalk scratches and whirring fans.
Our shared slick friction blended seamlessly into the noise.
Marin's pussy now gushed uncontrollably, a hot waterfall over my hand.
Droplets pitter-pattered to the floor, forming a puddle. The mint scent thickened, stinging my nose.
Marin's face flushed crimson; she slammed her head onto the desk.
"......That's it for today's class. Don't forget the assignment."
Drag.
Before the professor finished, Marin shot to her feet.
Grab!
She seized my hand and bolted from the classroom, hurrying somewhere in a frenzy.
