27th Rule: For Efficiency-Obsessed Marin, Help with Homework (3) ♥Marin♥
There are just way too many useless things in this world.
Like booze and smokes that wreck your health, or gaming consoles that suck away your time.
Stuff that's utterly pointless for actually living life.
Yet the masses always fall for the flashy packaging and chase instant gratification.
Then, when they crash into the brutal consequences, they blame society for their choices and curse the world.
They've cooked up far too many pointless rituals of their own.
And they shoot dirty looks at anyone who doesn't follow along.
So I've decided to treat those monkey-like idiots like ants.
No different from how I wouldn't care if some tiny, pathetic ant badmouthed me.
I couldn't give less of a damn what people say about me.
Even right now, with this slave gawking in shock at my bare crotch.
I... don't care at all.
Underwear is inefficient—that's my ironclad belief.
And this guy who can't get on board with that? He's just another ant...
"You mean... you're saying you want me to insert it?"
"...Got a problem with that?"
"N-no, not really..."
"Then quit yapping and get on with it."
"...Yes, ma'am."
Marin shot an irritated glare at the floor.
I shook off my flustered stray thoughts and gripped her petite ass from below, pulling it down.
Her slender legs began folding up right away. I could feel her slight weight shifting onto my lap.
If this kept going, my cock would surely plunge into her tiny body. But this woman showed zero hesitation, like she was used to riding guys.
Then, in one swift drop, her tight little hole softly pressed against my glans. Without pausing, I thrust my cock straight into that narrow entrance.
Ngh!
Insane.
Just the tip brushing in made me groan reflexively.
It clamped down with overwhelming pressure from the get-go, just like her uptight personality.
But I wasn't the only one struggling. For a split second, Marin's stoic face twitched.
"Miss... you okay?"
She shot me a quick glare, clearly annoyed by my worried tone.
"...No issue. Just... caught me off guard since it wasn't what I expected."
'Thought it'd be no different from Gomdori...'
I swear she muttered something like that, but it made zero sense, so I let it slide for now.
"R-right, then. I'll keep going."
She nodded, eyes dropping away.
I grabbed her sides and applied a bit of pressure.
Her forced composure started crumbling. The tips of her ears, once pale white, flushed bright red.
Squelch♡.
With great effort, Marin finally took my cock deep inside her.
"Hoo... ♡ Hoo... ♡."
She panted raggedly for a while, like it hurt, then slipped a hand under her clothes to rub her belly.
"...It's hot. And it keeps throbbing bigger inside... Ngh♡. Feels stable, but... breathing's kinda tough..."
The ever-cold and haughty Marin had lost her cool in an instant.
"...Size-wise, you pass."
...Is that good?
Hearing "pass" from a woman who seemed so merciless felt oddly satisfying, yet kinda ironic.
Whatever—good is good. Moving on.
"But... what exactly are we doing in this position?"
This was uncharted territory for me. I flashed an awkward smile from my chair, and Marin commanded:
"First, scoot the chair right up to the desk."
"...Like this?"
Glare.
I flinched involuntarily under her sharp stare.
But it didn't last.
"Ngh...!"
Marin suddenly shrugged her shoulders, eyes widening. Her gaze dropped downward again.
"Does this thing... usually move around inside like that?"
I wondered what the hell was twitching, then focused on my cock, buried root-deep in her cramped pussy.
She clearly wasn't used to the pulsing sensation inside.
"Y-yeah... I can't really control it... haha."
I gave a sheepish grin, but I still had my doubts.
She'd shoved it in without a second thought, but now she was acting all awkward, like a virgin.
It was confusing, but no time to dwell—Marin barked her orders in a sharp voice.
"Quit sitting there like an idiot and move already."
"...Got it, moving now."
"...Leave about a knee's worth of space."
Following her instructions, I slowly dragged the chair toward the desk.
Then, carelessly, it scraped across the floor.
Scraaaape, thunk!
Ngh!
The chair jolted to a stop. Marin's body atop me lurched forward; she grabbed my knees quick, clenching her pussy walls hard as she moaned.
"Grk♡! You idiot, the chair...!"
She was seriously freaking out—her inner walls clamped down like mad, screaming her panic.

"S-sorry!"
"Haa... ♡ Haa... ♡."
This is bad.
No words from Marin—just ragged breaths as she clawed at my knees.
After an eternity of squeezing my cock like she wanted to crush it, her grip finally eased. With trembling hands, she pointed at the desk.
"Pick up the chair... and move it slowly to the desk..."
"...Yes."
I complied eagerly, lifting the chair carefully with her straddling my thighs. As I straightened my knees a bit...
Sluuurp!
Her pussy folds clung and slid along my shaft. Her body stiffened in spasms again.
"You moron! When you stand, hold onto me... Hnng♡!"
Squeeeeal! Squeak! Squeeeeal!
Marin bucked wildly, squirting hot juices all over my thighs.
Ngh!
I couldn't take the insane pressure anymore and slammed back into the chair, wrapping my arms around her quivering belly.
Her face in that moment: eyes brimming with tears, pupils lost and wandering the air.
No choice—I hugged her belly tight and inched forward bit by bit.
Even that was clumsy, demanding way more strength and patience than expected.
And whenever the chair rattled with a scraaaape, her nails raked my knees, making even me wince in pain.
Less than 30 centimeters, but it felt like miles.
Finally, we made it with a sliver of space. The room filled with our heavy breathing.
"Hoo... ♡ Hooo... ♡."
After ages, Marin steadied herself with deep breaths and picked up her pen.
What the hell is she planning?
As I watched, cradling her belly warmly, she grabbed a thick textbook from the desk and opened it in front of her.
"...I'm doing my backlog of homework now, so don't interrupt. Just sit still."
"I-in this position?"
Not groaning or anything... she's seriously doing homework? With my cock clamped inside?
"...It's not your job."
"...True, but..."
"Just... having a dildo plugged in makes me feel stable somehow. Boosts my focus efficiency."
This woman's lost it, for real.
Efficiency my ass in this state. She's just catering to her own perverted habits...
But she acted like it was routine, resting her cool bare feet on my lap.
Scribble scribble.
And started writing.
Peering down, it looked like math equations—tons of letters, barely any numbers.
Guess this Marin chick majors in math or science.
Thump, thump.
Clinging to her back like this, I could feel her steady heartbeat pulsing through.
Totally tense, Marin ignored my throbbing cock and dove into her work.
But it wasn't boring.
When homework flowed smoothly, her pussy walls hugged me all cozy.
Then, when she hit a snag and bit her nails...
Squeeze!
Ngh!!
Her toes wiggled, and her walls wrung my cock like a rag.
She'd loosen up sweetly, then crush me if I let my guard down.
Just 30 minutes of being sheathed, and the urge to cum was overwhelming.
One wrong climax, and I'd get zapped again. I gripped the chair arms, holding back desperately.
Not easy at all.
Especially when she struggled for over five minutes.
Squelch♡, squelch♡!
Stomping her feet, she'd bounce her ass up and down.
Each time, her gripping walls tugged me along, flooding my brain with ecstasy right to the tip.
An absurd situation no normal person experiences. Pure agony.
Sluuuurp♡.
Her ass slid up slickly, then...
Slam♡.
...crashing down onto my thighs with ruthless gravity.
Her already vice-tight pussy endlessly swallowed and spat my cock. Meanwhile, Marin was laser-focused on homework.
I got sensitive to the rustle of flipping pages. Every scribble made her folds twitch.
I endured about an hour like that.
But I'm at my limit.
Her endless homework showed no sign of stopping. My maximally swollen cock in her narrow depths ignored my brain, drawing up semen to flood her.
Her work's not done yet... If I blow my load again, I'll be electrocuted toast!!
Body shaking, tears welling, but my cock marched to its own beat, defying my pleas.
And finally unleashed thick, hot white ropes.
Spurt! Spuuurt! Spurt!
The massive orgasm jerked my head back. My thoughts blanked white, ass bucking on autopilot in extreme pleasure.
Grkkk!!!
My long-steady erection deflated like a punctured balloon.
As it squished under her inner pressure, Marin finally seemed to feel the emptiness—her eyes dropped down.
But my instinct-driven cock kept going.
Spurt, spurt.
Pumping every drop into her like it was dead-set on knocking her up.
Stupid dick, I wore a condom this time...
...
I sneaked a terrified peek at Marin.
Our eyes locked.
Cold, expressionless face.
Click.
She set down her furiously scribbling pen and stared right at me.
I'm dead meat now...
