37th Rule, Finishing in the Bathroom with the Super Heated-Up Marin (2)
“Yeah, who would've thought a rude bitch like that would actually get a boyfriend.”
Splurt! Spluuurt!
Even as I eavesdropped on the guys' conversation with bated breath, my release just wouldn't stop.
My thighs and lower body kept twitching uncontrollably, pumping semen straight into Marin's womb until my balls were completely drained.
It seemed the tension and fear had melted into peak pleasure, my survival instincts desperately trying to impregnate her as fast as possible.
On the flip side, Marin's eyes were rolled back so far tears were streaming down her face. She was staring right at me, but there was no soul behind that gaze. All trace of her stubborn reason had vanished.
She'd surrendered completely to instinct, soaking the hand I'd clamped over her mouth with her warm, slobbery saliva.
Just as I felt her womb overflowing, the semen pushing back out, the guys chatting right in front of our stall revved up my cock even more.
“Fuck... She had a pretty face, too. If I'd known she'd go for a loser like that, I would've hit on her first.”
Splurt.
“Right? Her personality's a nightmare, but damn, that face and body...”
Spluuurt!
“That slut must've fucked her boyfriend's brains out in a motel, huh?”
Spluuuurt!
“You call that fucking? If it were me, I'd have emptied my balls completely!”
Spluuuuuurt!
The more I listened, the more my cock kept unloading.
There was no sign of it stopping.
My vision blurred as my mind went hazy, but claiming this hot female right in front of me—the one all these other males had lusted after—filled me with triumphant satisfaction. I'd beaten the competition and fulfilled my primal duty.
Just like they'd said, not a drop left behind. Every last sperm was shoved deep into her plump womb.
Glug, glug.
“Fuck, I'm so jealous! I wanna fuck her senseless too!” “Hey, if you're gonna cum, do it quietly! There are people behind you!” “It's just the part-timer, fuck off. Go take a shit. It's not like that slut's in the men's room.”
Drip.
No sooner had he finished than my twitching cock finally went limp.
The thick white load that had bloated Marin's belly started leaking out along with my shrunken dick, filling the entire bathroom with the musky scent of night-blooming flowers.
Then the guy who'd been yelling about sex just moments ago sniffed the air and shot his friend a creepy question.
“...Dude, doesn't this smell kinda weird?” “Huh? What?” “It's not shit—smells like cum.” “Cut the rude shit and get out if you're done. You're stinking up the place...” “Ugh... It's weird, though... Why's there this minty pussy smell in the bathroom? Gotta be that bitch's...”
Muttering in confusion, the guys slowly shuffled out.
Only then did Marin's tension ease, and the sticky semen cheese started oozing from her pussy down her thighs.
I released my hand from her mouth, and Marin—her face a mess of sticky drool—flashed a satisfied smile and whispered,
“Haa...♡ So, puppy? How's it feel to flood the womb of a beautiful woman all those monkeys were drooling over with your seed?”
Gulp. I stared at her face in stunned bewilderment at the question.

Marin lifted my chin, pressing her face close as if demanding an answer.
“I wanna hear it.” “...It was... the best...”
What more could there be? A bound slave, pouring his seed into his mistress's baby pouch.
She said she'd taken her birth control, but this raw, thrilling sensation—something condoms could never match—had me hooked already.
Marin seemed plenty satisfied with my answer, planting a kiss on my forehead and stroking my hair.
“Good boy, puppy... But my legs won't move... So let's rest here just a bit longer...”
Haa...♡
Marin leaned her face on my shoulder with an exhausted sigh.
We stayed like that, embracing on the toilet seat until lunch was nearly over.
In the meantime, some guy banged on the stall in a hurry. Someone next door crunched on pickled radish like it was a meal.
But Marin and I, drenched in thick pheromones that permeated the whole bathroom, just basked in the afterglow, feeling each other's heartbeats.
Finally slipping out when no one was around, Marin realized her embarrassment for the first time.
“Look at this, puppy. See how much you blasted inside me? My belly's sloshing around.”
Sticky white globs had been dripping since she stood up, so I kept wiping her with toilet paper.
But we couldn't be late for afternoon classes, so Marin rolled up some paper and shoved it right into her pussy hole.
Then she yanked at my pants.
“Gimme your panties, puppy...”
She swiped my underwear after stroking the cum off my cock...
Slurp, sluuuurp...♡
Kneeling with my panties in hand, Marin greedily licked up every last trace from my dick.
Right after cumming, my glans was hypersensitive—her hot tongue sent shivers down my spine—but all I could do was grip her hair and endure.
Once her post-cum cleanup was done, she tucked my panties between her legs like a prized trophy, covering her lewd, paper-stuffed pussy hole with them.
Marin licked the semen from her lips and shot me a look—like she wanted more.
I picked a curly pubie off her mouth and said,
“No matter how you look at me like that, there's nothing left...” “...Tch.”
Still, she kept lapping at my limp cock with regret, but no amount of effort would raise it again.
###
We barely made it to the classroom just before class started.
We sat in the very back row we'd reserved that morning, pretending to focus, but since it was a major unrelated to me, I just stared at Marin the whole time.
I figured after blowing off steam in the bathroom, she'd concentrate on class now.
Shh, shh.
But her first time wearing panties felt awkward, so she kept rubbing her thighs together, glancing down.
Eventually, her face flushed beet red as she scratched her crotch with a pen—lewd beyond belief, almost comical.
All classes finally ended, and as we headed back to the village shuttle.
Marin kept caressing her sloshing belly while walking, and until we reached the village, I had no choice but to keep scratching her crotch as she straddled my lap.
Were intelligence and libido really proportional?
Even back at the village, Marin's explosive lust showed no signs of fading.
She spun her chair around backward this time, hugging me outright like in the men's room and diving into her assignments.
With my dick hard and just sitting there, I teasingly tickled around her pink asshole, dotted with a tiny black freckle.
Hnngh...♡
Every time my finger grazed her sensitive skin, Marin shuddered and clenched my cock.
When it got unbearable, she'd glare at me and snap, “Don't,” but...
Shh, shh.
She didn't actually stop me—seemed to love that chilly thrill. Instead, she just panted hot breaths and drooled.
The next day was the same.
Marin and I rode to campus together, hitting the classroom, bathroom, and empty spots for sticky lovemaking just like before.
When we nearly got caught, her pussy would clamp down like it was devouring my cock, squeezing her already tight hole even narrower.
She got addicted to the thrill, boldly hiding in high-traffic spots to barely conceal my dick inside her.
By day five with Marin, I'd relentlessly pounded her precious hole without mercy.
Marin, relying on birth control, kept her pussy walls molded to my massive cock's shape, reeking of thick pheromones.
No sign of the cool, intellectual Marin anymore.
Now she was a full-on bitch in heat, shaking her ass like her tail was wagging—an illusion so vivid—gazing longingly at my face and cock in turn.
And so, day six with Marin began.
On the way to class, my bladder suddenly hit critical, so I whispered in Marin's ear as she clung to my arm,
“Miss, I need to hit the bathroom quick. Go ahead to the classroom without me.”
The moment I spoke, her arms tightened around mine—not just holding, but nails digging into my flesh with desperate urgency.
“Wanna come with? Let's make more memories~♡”
Marin grabbed my pant leg right there in the busy hallway full of students.
Uncomfortable stares from passersby made me glance down in panic—her eyes were glazed over.
Marin no longer hid her heat in public.
Like she didn't give a damn about the stares. She just craved my massive cock stuffing her vulgar pussy.
Part of me wanted to drag her lewd ass away right then, but with my butt clenching from desperation, I took her hand—wedged between her tits—and said,
“I'll be right back...”
I couldn't subject a noble lady to my foul stench, no matter what.
After agonizing, Marin sighed in resignation and let go.
“Hurry back.”
Freed from her grasp, I bolted for the bathroom.
That's when I saw it—a guy scowling at Marin, brushing past me toward her.
Something felt off.
I hesitated, watching, but...
Ugh!
My gut twisted like it would burst.
Leaving the guy in front of Marin behind, I had no choice but to dash to the bathroom.
