Summer Retreat at Ye-eun's House
A few days after the Retaker's Academy announced our summer retreat, the first day of summer break finally arrived.
"I'm off, Mom. Dad."
"Have a good time, sweetie. Make sure to thank Ye-eun and Hye-won for me!"
"Sure thing. You guys have a safe trip too, Mom."
I gave my parents a quick bow at the front door before dragging my suitcase outside.
Who would've thought things would go so smoothly.
When I told them I'd be staying at a friend's house during the Retaker's Academy summer break, they didn't hesitate for even a second—they gave their okay right away.
If anything, they felt bad about leaving me home alone while they were on vacation and even asked me to pass along their thanks to my "good friend."
Mom and Dad probably think I'm just gonna study diligently with friends there...

I gripped the suitcase handle tight and let out a secret sigh.
Of course, I'd told them I'd be studying hard at my friend's place, and since Seo Ye-eun and Kang Hye-won had decent reputations, it made sense they'd buy it.
But unlike my parents' rock-solid trust, I knew exactly what kind of treatment I'd be getting there.
High chance I'd spend my days not as a normal friend, but as a lowly bitch in heat, collared up and wagging my tail.
Just thinking about it brought a twinge of guilt for deceiving my parents... right alongside a filthy thrill that made my lower belly tingle with heat.
I must be totally insane.
Walking into what was basically a prison with my own two feet, and my heart's pounding like this.
Hoo... W-whatever. It'll work out somehow.
Pushing the worries aside with that thought, I hopped in a taxi and headed to Seo Ye-eun's house.
I rode the elevator up, rang the doorbell at her front door, and it swung open not long after.
"Oh, you made it?"
"Yeah... You're already here?"
"Eh, nothing to do at home alone... Damn, you pack like you're emigrating or something."
The one greeting me today was Kang Hye-won.
She grumbled a half-hearted scolding but smoothly snatched the heavy suitcase from my hand and headed inside.
I didn't need to be babied like this.
No idea if she was looking out for me or just making sure I couldn't bolt with my stuff, but I decided to think positive.
"Thanks, Hye-won. But where should I put my luggage...?"
"Oh, that. This way."
"Huh...?"
Kang Hye-won led me to a room at the end of the living room hallway.
Door had always been shut tight before—I'd never been inside.
The moment it opened and we stepped in, my eyes went wide in surprise.
I'd figured it was just storage or a closet since it was always closed, but nope—a surprisingly spacious room unfolded before me.
"Whoa... There's a room like this?"
"Dunno, first time I've been in here too. It was empty before, but Seo Ye-eun said she prepped it for you."
"Really?"
"Yeah. Ask her for details. Unpack however you want."
Kang Hye-won set my suitcase by the bed and left the room.
As the door clicked shut softly, I let out a relieved sigh and plopped down on the bed.
A neat single bed, desk, wardrobe, even a full-length mirror—giving me my own room like this.
Didn't expect her to prep a whole room for me. Figured I'd just crash on a futon in the living room.
The place was already pretty big for someone living alone, but multiple rooms? Had no idea.
She definitely lived by herself—no family around—but why was the house this huge?
Suddenly, I remembered that time she rented out an entire motel floor as a punishment game excuse.
Setting up a place this big for a girl fresh out of high school, barely an adult, and handing her enough pocket money to book a whole floor without batting an eye.
Just how loaded was Ye-eun's family?
No wonder she has that classy vibe despite being a delinquent...
A bunch of questions bubbled up, but I decided not to voice them.
Asking outright would be rude,
and more importantly, waiting patiently until Seo Ye-eun told me herself was the proper posture for a good pet.
I shoved my stuff to one side and headed back to the living room, where Kang Hye-won was spreading out a thick futon under the sofa.
"Hye-won, you're not using a room? Sleeping there?"
"Yeah. Air-conditioned living room floor under the sofa's the comfiest for me. You take the spare room."
"Oh... Okay, got it."
"Speaking of, when's Ye-eun getting here? Said she'd grab something on the way..."
-Click!
"What, you here?"
Right as we finished sorting things out, the homeowner herself—Seo Ye-eun—unlocked the front door and strolled into the living room.
She carried a convenience store bag stuffed with all sorts of snacks.
Seo Ye-eun set the bag on the living room table and smiled at me.
"Oh my, Seojin's here? You got here quick."
"Y-yeah... Nothing to do at home anyway."
"Perfect~. Now that we're all here, how about some snacks and a little chat?"
Seo Ye-eun unpacked the bag onto the table and settled down in front of it.
Kang Hye-won and I joined her around the table.
As we munched on the snacks she'd bought, she kept smiling and continued.
"First off, a big welcome to you two for our Retaker's Academy summer retreat~."
"Summer break's boring anyway. Might as well hang out and study together—should be fun."
"Y-yeah..."
"You're both friends I trust, so no need for strict rules, but since we'll be living together for a few days, let's go over a few basics."
It was only natural to have house rules at a friend's place, even with close pals.
Especially with girls—they'd probably enforce the girly ones strictly.
Kang Hye-won and I sat side by side on the carpet in front of the sofa, watching Seo Ye-eun.
She looked back and forth at us, then raised one finger.
"One: During the day, we strictly follow the schedule for intense college entrance exam prep. Everything else is free time."
"Study?"
"Duh, Hye-won. We're here to study, right?"
"Hm... Not to fuck this horny bitch we dragged along?"
"Eek...?!"
"Kidding, you slut—why so jumpy."
Kang Hye-won laughed and patted my shoulder lightly.
Didn't sound like a joke at all...!!
I ducked my head to hide my flushing face.
Still, so far it sounded like normal study rules.
I'd braced for getting stripped and turned into a slave bitch right away, but this seemed manageable...?
"Two: At night after studying, we'll have a quick quiz on what we learned today."
"Quiz?"
"Yeah. Remember last time? We make questions for each other to solve."
"Oh, that format."
"And based on the quiz results..."
Seo Ye-eun smiled at me.
"The one who gets first place sets a special rule we all have to follow for the rest of the day."
"Special rule...?"
"Yep. Anything goes, but nothing too ridiculous, okay?"
"Y-yeah..."
"We follow it until study time the next day. Sound fun? We can make the days pretty interesting, right?"
I nodded at that.
Obviously, if Seo Ye-eun or Kang Hye-won took first, I could guess the rules: legally turn me into their pet or slave and have their way.
But flip it—if I got first?
Then I could steer things my way.
If I was tired or couldn't handle play, just make a "rest" rule. Otherwise, set minimal safeguards so they could dominate me lightly.
Nice—not bad at all.
"Sounds good. Could be fun."
"Yay~. You in, Hye-won?"
"Sure, why not. Seojin might be right—could be entertaining."
"Great~. It's the first day of break, so no brain-melting quizzes. How about a light game to pick the winner instead?"
"Game...?"
"Yeah. Starting with study on day one is way too human~."
Couldn't argue with that.
I'd crammed a bit before coming over just in case, but a game showdown beat a quiz for not frying my brain.
Plus, games played to my strengths.
Even if I'd slacked on gaming for pussy play lately, I'd been a casual gamer not long ago.
Beating these two delinquents? Easy.
"Alright, let's do it."
"Seojin picks the game then? Our Seojin loves games most, so she'll choose something fun~."
"Yeah. I'll pick."
And she was letting me choose the game?
I glanced around, pondering options.
PC or console? Total win for me—but nothing like that in sight.
Board game it was, then.
That's when I spotted a deck of playing cards tucked under the TV cabinet.
"How about... a quick game of One Card?"
"One Card?"
"Yeah. You both know the rules?"
"Know 'em~. What about you, Hye-won?"
"One Card? Total classic. I'm down."
Perfect—they bit.
I'd played One Card tons back in high school on trips and retreats.
Luck played a part, sure, but it had strategy too.
With my experience, I'd have the edge.
Great—when I win first, no gagging me. Gotta secure my right to speak.
With the safe word, I could handle anything—as long as I could say it.
With that in mind, I grabbed the deck.
