Seventh Rule: Knowledge about Men for the Inexperienced Rio (1)
"Come in. Take off your shoes over there."
Guided by the blonde beauty Rio, I stepped into the mansion.
The pristine hallway, adorned with gleaming white marble, immediately caught my eye, along with the masterpieces hung at regular intervals along the corridor.
According to Amelia, the name Rio came from heliodor, a yellow gemstone.
Miss Rio was a freshman who'd just started university, taking Western painting classes at a prestigious art school to nurture her talent for drawing.
A closer look at the paintings on the walls revealed they were all signed with [RIO], as if they were her own works. But the subjects were a bit peculiar.
They were all pictures of men...
No landscapes or still lifes in sight—just portraits of handsome men filling the corridor.
If I had to point out something odd, their faces all seemed vaguely similar somehow.
...Probably just my imagination?
As I strolled down the hall, admiring these curious paintings, Rio, walking ahead, spoke up.
"I heard the gist from Ruby unnie. You caused a huge scene this morning, huh?"
"Yes. I heard I broke the rules and put everyone in a real bind..."
"Hmm, yeah. The whole village was buzzing about it all morning. But don't worry about that part."
......
"Pardon?"
"Haha, why so surprised? I've already forgiven you. Truth is, I couldn't care less about that side of things with you."
"...Could you maybe explain what you mean by that?"
"Huh, what?"
As if caught off guard, Rio stopped in her tracks and turned to look at me.
"You didn't even know what the rules were about?"
Overwhelmed by guilt toward Ruby, I averted my eyes from her gaze and nodded.
The air in Rio's bedroom was thick with the sweet, feminine fragrance wafting from her.
I sat on the desk chair as she explained the rules to me.
According to her, when they bid on me, there had been discussions about slave ownership.
Originally, each lady was supposed to get one slave, but Ruby's impulsive action had forced them to pool their entire budget on just me—that was the whole story.
"Of course we demanded a refund. We couldn't just burn 50 million won each—four of us—for something like you. But Ruby unnie's so stubborn... In the end, she paid the full 4.8 billion and they settled on two conditions."
Rio held up one finger as she spoke.
"First rule: Residents here have absolute ownership of the slave for one week."
She then rested her chin on her hand and stared straight at me.
"It's my turn starting today for the week. Which means Ruby unnie barging in this morning and messing with you was a clear violation of my ownership rights. Her turn's dead last."
"...So that's how it was."
Once again, I felt a surge of gratitude toward Ruby.
After all, I'd blasted her lifesaver's face with cum. I deserved to die for that.
"Anyway, that's all water under the bridge. The second rule... somehow feels like something you shouldn't know, so I'll skip it! Just take good care of me for the week~."
With a sly grin, Rio plopped down on the bed.
Before I could even wonder what the second rule might be, she patted the spot beside her.
"Come here for now? I'll explain what you need to do from right here."
Gulp.
A bed... and a man and woman alone.
Even if she claimed zero interest in me, the flow screamed physical service.
Imagining what might go down on that bed, my dick started stiffening again.
I sat on the edge of Rio's bed, my crotch bulging noticeably, when she fidgeted awkwardly and slipped a hand under her skirt.
......?
She hesitated for a moment, glancing away, then...
"Ugh... whatever! Here, take this!"
Swish, plop.
She yanked her hand out from her panties, and a mysterious photo landed swiftly in my palm.
"M-Miss? What is this...?"
The photo still carried the warmth of her body. It featured a handsome guy, absolutely drenched in some unidentified fluid.
When I scooped up the liquid with my finger, a thin string trailed after it.
How the hell did this end up there...? I had no clue.
I stared at Rio in utter confusion, and she turned away, mumbling softly in embarrassment.
"He's a senior from my department... So, so handsome that just looking at his face soaks my panties... I tucked it in there to hide the constant leaks, but his face felt so gentle licking me that I just... couldn't help it..."
Verdict: This innocent-looking girl was just as batshit crazy as the rest.
Thud thud!
I'd almost fallen for her wholesome first impression.
Looking closer at the photo, I realized his face matched the men in the hallway portraits.
"...So, what kind of service do you need from me?"
I couldn't even guess. The sour scent from the photo was making my head spin, but that wasn't the main reason.
Grab.
Rio clasped both my hands tightly, her face shy. The same hands that had just fondled that soaked photo now overlapped mine.
"Teach me..."
Her bright yellow eyes glistened with tears.
"Everything... about men. From one to ten, all of it."
First, I got the rough gist of her situation from Rio.
She'd grown up under her father, a bank CEO who controlled massive cash flows.
Banking is a field that tolerates zero mistakes, so her father was strict with everyone—but lenient with her. He'd support whatever she wanted to pursue, even overlooking actions that bent common sense a bit.
That kind, supportive father who cheered on his daughter's happiness and future had one unbreakable rule.
"He absolutely forbade me from getting anywhere near boys. So from elementary school through girls' middle and high school, I only hung out with other girls. He even pressured me to apply to a women's university because he hated the idea of me mixing with guys."
In short, she'd nearly gone down the nun path.
"That's why I have no idea what guys like or what to do for them... I studied theory from books and the internet, but real life is different, right? So first, tell me what men like!"
"Wh-what men like?"
Hmm, what could it be?
Cars, watches, gadgets, comics, anime, and so on...
"Tastes vary wildly from guy to guy, so..."
"Then isn't there something universal? Something every guy goes crazy for."
Universal...
My eyes drifted to my bulging pants, thanks to her heaving breasts rubbing against me. Rio's gaze followed mine.
Whether from the photo fresh out of her panties or the fishy scent from her hands...
My zipper-sealed dick was twitching like it was screaming, The answer's me!
"Looks like this guy's it..."
......
Rio stared at my crotch with a rotting expression for a long while.
"For real...? If I handle this, every guy will like it?"
"Yes. Unless he's gay, no man hates a woman touching him there. Especially not you, Miss Rio—you're gorgeous, with a model-slim figure. Guys would lose their minds."
Whoosh.
My honeyed words clearly hit the mark; her clasped hands grew hotter.
But there was no lie in what I said.
The more instinct-driven the man, the more he craves claiming a beauty.
"...You too?"
"...Pardon?"
"You! Do you wanna do it with me too!!"
Her voice was sharp, but laced with eager anticipation.
"Of course. I'm a man too, you know."
"For real? Not just 'cause you're a slave?"
Her need for reassurance was a bit annoying, but also kinda cute. So I gripped her hands tight and delivered the knockout blow.
"Yes. From an objective male perspective, you're more beautiful than anyone in the world. Like a goddess."
Hnng!
Rio's eyes trembled like there was an earthquake. Her face was beet red, on the verge of exploding.
As we locked eyes like that for a while...
Whoosh.
She yanked her hands free and hurriedly shoved them toward her panties.
Through the gaps in her fingers, I glimpsed her soaked teddy bear panties. She was clearly trying to hide a fresh gush of juices.
After fidgeting awkwardly for a moment, Rio commanded in a trembling voice.
"Then... show me."
"Sh-show you wh-what...?"
"Seeing is believing. I need to see that... monstrous dick of yours with my own eyes. Hurry!"
"Y-yes, ma'am!"
Clink clank.
In my haste to obey, I fumbled toward my zipper—but sitting down made it impossible to reach properly.
"Sorry, Miss, my hands just—"
"Ugh, seriously! Such a hassle."
Grumbling all the while, Rio unzipped my pants herself.
My proud erection burst free from my underwear...
Smack.
...springing up like a coiled jack-in-the-box to slap her cheek.
Squish, squish!
Unintentionally tensed, it pressed against her cheek. Rio stared at me blankly with huge, wide eyes.
