Rule 30: Marin, Who Desires the Slave's Submission, and Semen Endurance Training (2) ♥Marin♥
I'm pissed.
Pissed, pissed, pissed.
Just this morning, I'd woken up so efficiently, and the puppy had been so adorable.
But the moment I approached the front door with his cock wedged against the wall, the irritation started flooding in.
The whole entrance reeked of Ruby's fancy black tea.
Still, I didn't let it show then. No matter how steamed I was, the task at hand came first.
Besides, even if this guy was mine right now, he was basically public property for the entire village.
So I figured I could just brush it off.
But cumming in thirty minutes? That's a whole different story.
Today's schedule was light on assignments, leaving plenty of time for self-improvement afterward.
But this big, dumb mutt with zero self-control spurted his hot load at the worst possible time, and now his cock had shriveled up.
This throws my entire plan off the rails.
While I was racking my brain for a way to train him properly, I came up with the perfect idea.
Something ideal for a horny mutt who pops a boner for any girl—a method that maximizes efficiency and lets me monopolize this living dildo.
I clenched my lower abs hard, channeling all my frustration into it.
The pussy walls, toned from constant dildo use, clamped down on the puppy's cock with brutal force. As I pressed my body tight against his and looked up, his expression was...
Grk!
Perfection.
Especially the way he bit his lip—pure gold.
Aah, I want to torment him. Break his ego and rewire his brain to my exact tastes.
Sure, cumming now means a high chance of pregnancy.
But with this massive dick of his, I could make it my personal toy forever.
So cum already, puppy. Stamp your claim deep inside me, make it yours alone. The second you do, you'll be my eternal living dildo, forever trapped at my bedroom door.
*Schlurp♡. Throb♡!*
I rocked my hips wildly, reveling in the secure fullness stuffing me tight.
"Come here, puppy. I'll show you what happens if you spill your seed carelessly again, just like before."
I'll make sure you never carry another bitch's scent. You'll scream my name alone when you blow your load.

★Toilet★
*Throb♡, throb♡, throb♡, throb♡.*
My eyes lost focus.
When I tried staring at the ceiling to ignore the violent pleasure surging through my cock, all my nerves zeroed in on it, making it even more sensitive.
But looking at Marin's face, yanking my collar? That cold beauty might end up carrying my kid—and the thought ignited a savage conquering urge.
No escape.
I was trapped in the coils of a massive python named Marin, utterly helpless.
"Haa...♡ Hold it back, no matter what. Got it?"
Marin let out a hot sigh as she ground down on my cock.
Her voice was firm, but for some reason, she wore a sly, predatory smile. Like her mouth and body were operating independently.
*Squelch♡.*
Every time, her womb kissed the tip, threatening to unravel my control.
With every word she uttered, it felt like holding back got harder and harder.
*Squelch♡.*
"Haa...♡ You know what? A woman's womb can get pregnant just from the precum leaking from your urethra~."

Grk!
Please... stop...
*Throb♡.*

"Haa...♡ It might already be too late, so wouldn't it be easier to just go full beast mode and flood me with your seed?"
Marin's temptation dripped like honey-coated candy, so sweet.
My locked muscles slackened for a moment, teetering right on the edge of eruption.
If it was already too late like she said, maybe I should just surrender to this hellish bliss and unload everything deep inside her.
But I clenched my lower abs desperately, forcing the thick load back upstream.
Then Marin, like some competitive fire ignited in her, swallowed my cock whole and started grinding her hips side to side, wildly swirling.
*Squelch♡, squelch♡.*
The glans, glued to her womb mouth, tempted me with that lewd motion.
Her pussy folds milked my shaft like squeezing a cow's udder, forcing my eyes shut over and over.
Marin ordered me to hold back at all costs.
But her words and body's filthy signals screamed for hot semen to gush from my tip.
This was blackmail.
Like a thug shaking down a mark in a dark alley, her womb openly demanded my cum.
Haa...♡.
Every time I made a whimpering face, Marin exhaled toward me with a melting expression.
That hot breath. That musky scent. That sticky humidity.
It loosened my abs for a split second, plunging me into crisis.
But I squeezed my eyes shut, tears streaming like a wimp, and in that instant, hugged Marin tight to barely hold on.
The moment my arms wrapped around her back—
"Eek!"
Marin widened her eyes in surprise, glaring at me.
"Y-You stupid mutt... jumping me without warning—hnng♡!"
*Squiiiirt! Splurt! Squiiiirt!*
Marin gushed hot tides all over my lower belly, flopping in my arms like a fresh-caught fish.
Then her body tensed in spasms, her rigid pussy walls squeezing my cock like a wrung-out rag, driving me insane.
Uuugh!
I'm gonna black out.
But I had to stay sharp. Getting cocky now could waste all my endurance.
Even as my vision whitened and hot liquid soaked my belly, I clung to reason.
"Haa...♡ Haa...♡ Hnng...♡!"
Marin, riding her climax, shuddered periodically in aftershocks.
With her face buried in my chest, every breath heated my skin. The squirt soaking her sweater quickly cooled against my belly.
Fuu...
Each inhale caved her belly into mine.
Like she'd lost or something, Marin trembled in my arms for ages.
Lost in the afterglow, panting hot breaths—then she scowled up at me.
"Puppy... you're more enduring than you look. Unnecessarily so..."
Even as she said that, I was still teetering on the brink, pure agony.
Her first orgasm loosened the grip, but now her pussy walls gently stroked my cock, teasing nonstop.
I gripped the chair back with both hands, enduring.
Fuu... fuu...
My breathing ragged, head spinning.
Legs cramping from the strain—
*Schlurp♡.*
Finally, Marin slowly rose from the chair, pulling off my cock.
The tight entrance grazed my glans one last time—
*Pop!*
*Splurt! Spuuurt!, spuuuurt!*
A near-disaster. The massive, pent-up load rocketed through my urethra in a scorching blast.
Like a sprinkler, it painted the whole room—and Marin's body—white.
*Drip, drip.*
Our eyes met as cum splattered her face.
Blink. Blink, blink.
Confused, she wiped the sticky semen from her cheek.
...
Shadows crept over her face like a villain's transformation.

"...What should I do with a naughty puppy who pisses all over his owner's body?"
Marin glared down, clenching her cum-smeared fist.
My spent cock hung limp, no defense left. No one to save me now.
"...Haha. Yeah... what should we do...?"
With this vulgar, hyper-potent dick that unloads like crazy at the sight of its mistresses...
###
In the end, using the excuse that I'd dirtied her body with cum, I was dragged to the bathroom to wash her every inch.
*Swish, plop.*
Marin tossed her reeking clothes—squirt and semen mixed—into the hamper.
Her panty-less body was fully exposed, defenseless.
Not as skinny as Ruby's, but slim with nicely swollen tits.
Especially when she stepped into the shower first—those plump, jiggly ass cheeks stole my gaze.
Round and meaty like puffed cheeks, but right below, the smooth pussy hole that had gripped my cock so fiercely peeked out shyly, unlike its bold owner, flaunting a lewd allure.
*Slide.*
Marin opened the shower door, arms crossed, shooting me a cold glare.
Dried, flaky cum still clung to her sculpted face—like semen on a plaster statue.
"...What're you doing? Hurry up."
Staring at her perky nipples poking through her crossed arms...
Guess shame wasn't in Marin's vocabulary.
"Can't you see my precious time melting away because of you?"
"...Coming right now."
