28th Rule, Basic Bedtime Etiquette for Well-Behaved Puppies (1) ♥Marin♥
In moments demanding intense concentration, I'd always force a massive dildo deep into my gut.
Like how some people crave spicy food whenever they're pissed off.
Filling my inner walls to the brim with a dildo was my personal way of relieving stress.
It naturally dissolved the sexual urges that disrupted my focus, letting me immerse myself completely, no matter the surroundings.
Extreme efficiency that converted waste into fuel.
This was the pinnacle of the life philosophy I pursued.
Especially when I'd clamp down hard on a dildo so enormous it felt like it might rip me apart with my vaginal walls.
For some reason...... my mind would settle into peace.
That's why I'd never experienced a real man's cock directly, cherishing the assortment of dildos in my room like prized collectibles above all else.
They were cold and squishy, but nothing else came close as a substitute.
......
But the first time I encountered a big, rock-hard real man's cock.
What I'd dismissed as mere fleeting fun proved utterly wrong the instant I took it inside me—an unprecedented wave of pleasure crashed over me.
Its unyielding hardness that wouldn't yield no matter how hard I squeezed, the throbbing pulse within, the way it kept swelling even past my limits, and the scorching heat that set my insides ablaze.
The dildos I'd favored before felt like pathetic knockoffs; the real thing delivered satisfaction on an entirely different plane.
Especially when it twitched like it was hitting climax. The sensation of my entire vagina heating up brought an indescribable comfort.
But.
......
For some reason, my lower body was starting to feel emptier by the second.
Just moments ago, it had been swollen rock-hard inside me, ready to burst.
Now, even a slight squeeze from my vaginal walls made it yield—it was softening and shrinking.
This was the post-ejaculation refractory state I'd only heard about. It matched textbook theory perfectly.
My concentration shattered unintentionally, irritation bubbling up.
But even as I furrowed my brow to check the results so far.
"......Impressive."
Rustle, rustle.
No matter how I flipped through the pages, the outcomes were unbelievable.
Problems that had stumped me for days were now solved perfectly, complete with clean solution paths, in a mere few hours.
Sure, I'd struggled a little here and there, but time-wise, it was historic performance.
But...... regrettably, that's as far as we go.
Slurp♡.
A squeeze of my vaginal walls, and out slipped the slave's pathetic dildo, limp and trailing. The overstretched condom, heavy with yellowish semen, plopped to the floor.
I stared at the slave, my gaze a turbulent mix of awe and annoyance. The pitiful thing apologized with a clueless, lost expression.
"S-Sorry."
His naive innocence only stoked my anger further. I considered drilling some thorough training into him, but...
......The efficiency had far exceeded expectations, so my rage evaporated in an instant. Hell, I even felt like rewarding him.
As I ran mental simulations on what to do with this puppy, a brilliant idea hit me.
I closed the textbook and turned to the bio dildo.
"You, are you really sorry?"
"Y-Yes...... Huh?"
There we go. He bit the bait.
This dildo seemed to have some spine back in the public toilet, but up close? Just a naive, easy-to-use puppy.
To dig into that weakness, I sat facing him casually, arms crossed, and said,
"Then sleep here tonight."

★Toilet★
I glanced around at Marin's sudden invitation, then asked her, brimming with confusion.
"Is there a spare room or something?"
"......There is, but you'd be sleeping on the bare floor. I don't keep extra blankets around the house."
"......Then where do you mean I should sleep?"
Her proposal made zero sense.
My barrage of questions must've irked her, because she furrowed her brow slightly and jabbed a finger at her bed.
"You doing this on purpose? Here. Sleep in this bed. Don't wanna?"
"N-No...... It's just, sharing a bed with a woman I just met feels kinda......"
I trailed off, but damn, it was awkward as hell.
A total stranger. And not some sweet type like Amelia or Ruby—this was prickly, hot-tempered Marin for a whole night.
I'd take my one and only home, the slightly smelly public toilet, a hundred times over.
Worse, this woman was a psychopath who'd slapped a brutal electric shock on my collar without a shred of guilt.
Somehow I'd piqued her interest instead of wrath, but sticking close? Bad things were guaranteed.
"Fine, if you wanna shiver on the floor without a blanket like some mutt, I won't stop you. Not like I'm soft-hearted enough to care about your pathetic whining. But that's inefficient, right?"
"......Y-Yeah......?"
"It's late anyway. Management office now? Just guards, and they won't bother letting you in."
......The more she talked, the more convinced I got.
At first, I figured she just wanted to torment me by keeping me overnight.
But her efficiency pitch? Even I had to admit it made sense.
Still, there was a flaw in her logic.
I always had someone who welcomed me warmly at night—
"Oh, and don't even think about crashing with Ruby or Raven."
......What the—? Did this woman have mind-reading powers?
I hadn't said a word, but she nailed it right on the head. Spot on!
"......No need to look so shocked. Everyone in the village knows everything. Usually Ruby and Raven walk you home, super nice about it."
"Y-Yes......"
"Anyway, they're out of the village for a bit. Grandfather called 'em—health stuff, business handover, whatever. Don't care. Ruby just asked me to pass it on if you came looking."
Her words conjured up my last talk with Ruby.
—Hey...... Can I hold you like this, all warm, every single night?
We'd made that promise...... but I hadn't seen her since getting stuck at Hyo-eun's place.
So her health acting up? Probably caught another cold waiting for me, like last time......
Had to be. She had a history, and Amelia once said Ruby was famous for her strict self-care.
Imagining her shivering under blankets twisted my gut with worry.
"So, what's it gonna be? Quit stalling and decide."
As I stared at the floor in anguish, Marin tapped her crossed arms impatiently.
Something felt off.
I was her property, right? So why wait for my answer?
One command to "stay," and as a slave, I'd have no choice but to obey.
Made me suspicious.
This urging didn't match her usual bulldozing style.
Part of me wanted to refuse out of doubt, but I couldn't bring myself to.
It seemed like she was asking my opinion, but it felt like veto power wasn't an option.
Like her logic was ironclad, and she didn't even consider I'd say no.
So, staring at my spent, semen-drooling cock hanging limp, I mumbled weakly,
"......I'll stay."
And in that instant.
For a fleeting moment, Marin's lips twitched upward, almost like a smile.
"Smart choice. If you'd rejected after all that convincing, I'd have zapped you into obedience."
Called it. No way I could ever like this ruthless woman.
♥Marin♥
Perfect.
This guy's turning out way more fun than expected. I like him.
Still need more training to know for sure, but.
That monster cock outclassing every dildo in my room, plus surprisingly obedient attitude?
More than enough to win me over.
Average looks? Whatever, never cared. Dumb thought process like every other monkey out there? Minor flaw, no biggie.
So I decided to raise him into a proper pet.
Dogs and cats? Can't communicate, not interested.
But a slave this smart? We could actually talk. Worth the investment.
Train him right, and after a week he'll stick to me, supplying top-tier bio dildo on tap.
Hell, might even revolutionize academia.
He should be grateful.
He'll be the only one getting attention from a genius driving human progress.
First things first: time to instill some discipline in this beast.
Thud.
I slid off his lap and sat on the edge of the bed.
Without hesitation, I spread my legs wide, fingers parting my outer labia, shoving it right in his face.
It twitched, stirring back to life.
A rare smirk slipped out after ages.
But I kept a straight face, issuing my first command to make him my puppy.
"Alright, before you get in bed, come here and kiss this."
Something from a book flitted through my mind unbidden.
Medieval knights kissing their lord's ring to pledge loyalty.
No ring? Fine, swapped it for the part he should treasure most down below.
This puppy would prefer it anyway.
Unlike vulgar sluts, a chance to experience a noble, beautiful woman's pussy up close? One-of-a-kind.
My heart raced for the first time in forever.
Excitement from finally finding a candidate for my first-ever pet.
