27th Rule, For Efficiency-Obsessed Marin, Help for Assignments (2)
“Come on in. This is my room.”
I stepped slowly inside, glancing around.
She froze for a moment with a startled look, then snapped irritably, like she had something to hide.
“...What? Something wrong?”
I quickly looked up at her face. Her coldly mechanical expression had a slight furrow between her brows.
“N-no, nothing...”
“...Then get in already. Don't dawdle.”
She brushed it off verbally, but that strange feeling wouldn't settle.
The walls were papered in a clear blue like Marin's hair.
Unlike the empty hallway, the bed and dresser were crammed with teddy bears of all sizes.
And one entire wall was taken up by a display shelf packed with rainbow-colored dildos.
Bigger than average, but a bit smaller than my little guy here...
And that black one looked freshly used, still slick. Touch it, and it'd probably feel slippery...
That wasn't all.
A massive teddy bear on the bed had some unidentified plastic holder tucked under its plump belly.
I had no idea what it was for, but it screamed extreme filth.
This shock dwarfed even finding that damp, warm photo in Hyoeun's panties.
It almost made me think all rich girls had these bizarre tastes.
Drag.
In this situation where I couldn't guess what she'd do next, Marin pulled up a chair and ordered,
“Sit. No time to waste—hurry up.”
Totally dog treatment.
Her icy tone felt a bit off, but I sat down anyway.
Right in front of me was a desk piled high with books next to a reddish-brown bookshelf.
What the hell is she planning...?
I swallowed dryly in my unease, and Marin started scrutinizing my dick—the one that had been twitching wildly under Amelia's comfort all the way here.
She measured its length and girth with a plastic ruler from the desk, jotting notes, then
“Hmm, size is decent. No, actually bigger than the teddy bears.”
“T-teddy bear?”
I blurted out in confusion, but she ignored me completely, tossing the ruler aside. Then she leaned in, sniffing my dick.

Zap.
She grabbed the shaft—too thick for one hand—and glared at me.
“It stinks a little... You do wash properly, right?”
“W-well, we rushed out, so no shower...”
This woman didn't even give me time to dress—what the hell?
“...Fair point, I guess. But wash ahead next time. Or I'll peel off that smelly hide of yours.”
“...Understood.”
A scary condition added, but surprisingly, she accepted my excuse.
Back to her indifferent face,
Clunk.
She pulled out a bottle labeled IPA and a scrap of white cloth from the desk drawer.
Squirt.
With expert finesse, she soaked the cloth in the liquid.
The sharp alcohol smell from childhood science labs stung my nose.
“Miss... what is that...?”
“This? Snagged it from Dad's factory. He's big in semiconductors. ...Relax. It's not real alcohol—just diluted hand sanitizer.”
That's not reassuring at all...
As I tensed up, she forced my legs apart and knelt between them.
Wipe, rub.
Then, with surprising gentleness, she cleaned my dick thoroughly with the sanitizer-soaked cloth.
Unlike her rough drag here, she handled it like fine china—soft, delicate touches.
Especially the smooth white fabric; it felt like silk gliding over skin.
Every pass of the booze-laden cloth brought that stinging tingle, making it twitch.
When she pressed firmly into the glans,
“Guh!”
Ejaculation pressure surged from my balls; I gripped the chair without thinking.
Marin noticed the twitching in her hand and blew on it to evaporate the alcohol.
“Fuu~. Hold it. Cum now, and I'll force it back up.”
“...Yes.”
Her warm breath nearly made me pass out, but I held on.
A week ago, I'd have painted her face white like with Ruby.
But that me and this me? Worlds apart.
Thanks to Catalina's brutal toilet training, I'd achieved shedding my mortal shell-level growth.
Thanks, Catalina. You're probably not in heaven, but you saved my life.
Anyway!
Unlike her frosty first impression, watching her focus so intently with that blank face...
...kinda made her look cute.
Her image had been rock bottom moments ago, but it was softening in my heart.
Dark web loner communities call this phenomenon gap moe.
“Done. Smell’s better now.”
That ticklish, savory interim cleaning ended; she tossed the cloth in the trash and pulled something else from the drawer.
It was a rubber sleeve custom-fit for my monster dick, just like Hyoeun's.
A condom...
Why clean so meticulously if you're covering it...?
As I sighed in complaint at her inscrutable mood, Marin peeled off the wrapper and slammed the condom down my shaft, pushing hard.
But
“...Why won't this go on?”
After grunting futilely, she shot me a prickly glare.
...Why ask me? Unreal.
Amateur moves for someone with a dildo collection.
No choice—I took her hand and fitted the condom myself.
Not my first rodeo; routine now.
Wait, shouldn't something like this not be routine?
Damn. Living in this absurd world had me turning absurd too.
Love it or hate it...?
Drag, click.
Once it was seated to the hilt, Marin scowled at my dick again, muttering. Her fists clenched in frustration.
“Didn't need help from trash like you...”
“...Sorry.”
Her dejected look made me apologize quick, stirring some odd emotion.
Her words dripped irritation, but oddly, it didn't bother me.
Not 'cause I'm a masochist freak.
Just... felt kinda pitiful.
Dunno why, but deep empathy welled up.
No time to ponder that tenderness, though.
“Grip your ass tight.”
Whoosh.
“...Huh? Whoa!”
This bratty miss suddenly turned her back, stepping up onto my thighs.
Panicking, I grabbed her soft, squishy cheeks—and looked up.
An unbelievable sight unfolded.
Her short blue skirt fluttered with the motion. Between her pert little ass cheeks:
Normally, panties or boy shorts would cover it.

Nothing.
Smooth pussy lips, slick with drool, faced me outright—red inner flesh on full display.
Even the puckered pink rear hole, dotted tiny, clenched tight in view.
Weird? Never saw her take off panties on the way...?
“M-miss? Did you... forget your panties?”
I asked despite how dumb it sounded, just in case.
But defying my caution, Marin looked down with vacant eyes.
“Oh, that? Don't worry. I never wear 'em. Hate inefficient crap like that.”
“...Pardon?”
No panties? Must've misheard.
My pupils quaked like an earthquake.
“Relax. Unlike you, I stay clean without 'em.”
What the actual fuck is she saying?
She's missing the point entirely. Cleanliness isn't the issue.
Normal women—no, any civilized 21st-century person, regardless of age or gender, wears underwear. National rule.
Even babies wear diapers. Flaunting your privates like this?
My afternoon gloom shifted to pure bewilderment.
But thanks to her nonchalance, my upright dick—still hard from sitting—hid her sticky pussy.
Spotting it, Marin bent her knees.
“Hold tight. Now I'm shoving your bio dildo all the way inside me.”
