Strip Quiz or Quit
Strip, or quit? If you get it wrong on the note quiz, you have to take off your clothes as punishment?
Such an utterly unexpected suggestion came out of nowhere, and my brain just froze solid in that instant.
“Oh, take off our clothes…?”
“Yeah! Doesn’t a penalty like that sound kinda fun?”
“I-I guess…? But we’re in the middle of studying right now…”
If this were a situation where I’d already become Seo Ye-eun’s pet and was being forced into all sorts of lewd acts, a penalty like this might’ve felt totally natural.
No, if it were that kind of situation from the start, I probably wouldn’t even be wearing clothes.
But right now, this was supposed to be a wholesome study group where retakers prepping for the college entrance exam were helping each other fill in their weak spots.
A penalty like this was completely out of line with anything normal…!
While my head was spinning in chaos, Seo Ye-eun smiled lightly and added,
“What’s wrong with friends doing a little something like that? We’ve even bathed together before, remember?”
“Ah, yeah… true, but.”
“Don’t be so shy~. It’s just a light penalty game between friends, right?”
I couldn’t come up with any retort to her words and just nodded blankly.
It didn’t sound wrong, exactly.
Stripping in front of opposite-sex friends would obviously scream ulterior motives to anyone watching, but there were only girls here.
And more than that, stripping in front of these two wasn’t anything to be embarrassed about.
I’d already stripped completely bare for other reasons—and gone way beyond that—with them before.
The problem wasn’t the lewdness of the penalty; it was the act of stripping itself.
I-if I strip in this situation… they might notice…?
Thanks to the filthy fantasies I’d been indulging in earlier, my panties were utterly soaked, sticky with my arousal fluids.
If I had to take off my pants, the wet stain on my panties would be blatantly obvious.
Even if I somehow got lucky and dodged that, losing more rounds and having to strip down to my panties would make it worse.
I could maybe hide the stains or make up some excuse for them.
But a pussy drenched and glistening with slick? There’s no hiding or explaining that away.
S-sure, I just need to get them right. But if I mess up and have to strip everything…?
Getting caught as the pervert who spent study time lost in dirty daydreams, leaking like a faucet.
What would these delinquent girls think then?
They’d probably say something like, “A bitch in heat even during study time? This slut needs lessons in something other than books.”
Then they’d collar my neck and shove that wicked tail plug up my ass…♡
*Drip*
“Ngh….”
Just imagining it sent a hot rush surging up from my lower belly, my body heating uncontrollably.
I clenched my trembling thighs, desperately shoving down the lewd anticipation radiating from my core.
First things first, I needed to calm down.
“H-Hye-won, you’re okay with this…?”
“Me? Doesn’t bother me at all. You’re the one who’s gonna end up stripping anyway, Seojin.”
“Hiiik?!”
“Beat me and Ye-eun for real here, and I’ll acknowledge it.”
I’d glanced at her expecting she might not like it since she’d been seriously studying, but she just propped her chin on her hand, smirking and waving it off.
Makes sense. From the perspective of Kang Hye-won, the inquiry monster who’d never missed a top grade, this was a no-lose game.
She’d win anyway, so no stripping for her—and this pervert enjoyed watching me strip naked and prance around.
D-do I really have to do this…?
Kang Hye-won wouldn’t have to strip, and even Seo Ye-eun, who might, was no easy opponent.
I’d be the only one left naked, and the nightmare scenario I feared could unfold.
W-whatever… let’s just try. If I don’t mess up, it’s fine…!
Honestly, part of me wanted to refuse, but in the end, I accepted Seo Ye-eun’s proposal.
The desperate urge not to strip would keep me focused on studying, and if luck was on my side, I might even get to ogle a naked Seo Ye-eun.
It definitely wasn’t because I was looking forward to getting exposed naked and in heat in front of them.
No way.
“A-alright. Let’s do it…”
“Great~. Let’s start right now!”
“Yeah, bring it.”
With all three of us in agreement, the strip penalty note quiz officially kicked off.
The rules were simple: Pick a problem from your notes, and the receiver had to answer within the time limit.
No matter how suddenly my heat switch had flipped during today’s study session, all that studying wasn’t for nothing—it stuck in my head.
Early on, things went pretty smoothly for me.
“Correct. Number 3, right?”
“Oh, Lee Seojin. Not bad? Been studying, huh.”
“Hehe… of course.”
“Hmm, this won’t be easy to strip her.”
“W-what’re you saying, you psycho bitch…!”
I grumbled at a seemingly disappointed Kang Hye-won, but deep down, I let out a huge sigh of relief.
Good, at this rate, I can coast through safely.
Even if I slipped up a few times, I’d layered up plenty today—I could peel them off slowly and endure.
That’s what I believed.
Until I saw that sight.
“What? Isn’t the answer 4?”
“It’s 3, bitch. You didn’t study this properly.”
“Ah, this one tripped me up a bit. My bad~.”
“Then strip, slut.”
“Got it, Hye-won~. Here goes…”
Seo Ye-eun gave the wrong answer to Kang Hye-won’s question and burst out laughing casually.
Then, without a hint of hesitation, she yanked off her crop hoodie.
The pale skin hidden beneath the black hoodie and her somehow seductive bra came into view.

“Phew, the room’s gotten kinda hot anyway. Perfect timing~.”
“Ah…”
Facing the massive presence her black bra couldn’t fully contain, all I could do was gasp in awe.
Holy shit, insane.
The fragile calm I’d been clinging to in my heart crumbled to pieces.
“What’s wrong, Seojin?”
“Ngh…. N-nothing.”
“Hng~. Did you wanna see me strip that badly? Pretty naughty.”
“N-nooo…! Not like that…”
“Okay, okay~. Your turn now, Seojin. Hurry and give a problem.”
“Right, next problem coming up.”
Kang Hye-won’s voice snapped me out of it, and I tore my eyes away from Seo Ye-eun in a panic.
What if I end up stripping like that too?
She’d see my body all aroused and worked up.
And if she pounced under the pretext of punishing me for getting horny over her naked body…!
C-crazy… calm down, it’s not like that…!
I tried to steady my mind somehow, but my body was already beyond my control, burning up.
My heart pounded like it was right in my ears, and slick gushed from my pussy, soaking my panties through.
No, I can’t keep getting turned on like this out of nowhere.
Calm down, Lee Seojin. Calm down!!
“Alright, Lee Seojin. Solve number 9.”
“Yeah…? Ah, uh…. Yeah…”
“Gave you an easy one. You can do this, right?”
Kang Hye-won tapped the note with the problem, and I started scanning it with my eyes.
Like she said, it was pretty straightforward.
A concept I’d just seen in the book moments ago—definitely one I knew.
But with my mind gone blank white, not a single word registered.
All that filled my head was the terror of having to strip—and the fantasies of the secret pleasure that would follow.
“T-that’s…. 4…?”
“Wrong. You blew it. Even this?”
“Ah…”
“You know what to do since you got it wrong, right?”
Kang Hye-won stared at me with cold eyes.
With shaking hands, I cautiously pulled off my t-shirt.
Honestly, losing just a t-shirt wasn’t a big deal.
The room felt mysteriously stuffy and hot anyway—I’d kinda wanted to shed it.
But once my crumbling composure met the reality of stripping, things spiraled out of control fast.
“Next, number 21.”
“Nngh…!?”
“Easy one too? Go on, solve it.”
My turn came around again, but the problem wouldn’t focus.
Once my concentration cracked, there was no recovering it.
Every time a problem came up, my head swirled not with answers, but visions of myself stripped bare and ravished.
“2…?”
“Wrong again. Strip.”
“Hik?!”
“Oh my, Seojin’s shaking? What to make you take off this time~.”
“Nngh….”
With each turn, my clothes vanished one by one: socks from both feet, the thin short-sleeve I’d worn under my t-shirt just in case, and even my pants.
Every inch of bare skin exposed brought a wave of shame that made my face feel like it’d burst,
but weirdly, stripping piece by piece built an inexplicable pleasure.
Once I was down to just my underwear, their gazes felt even stickier.
“Seojin, you’ve got nothing left to take off now? You good?”
“Nng… ngh…”
“Lee Seojin, this is your real last chance. Mess up here, and you’re stripping everything.”
“Hik?! B-but bra and panties are separate…!!”
“You took off socks one foot at a time earlier. That’s cheating.”
“Huuu…”
“Fine, get this one right and I’ll let it slide. Solve it.”
Her fingertip pointed to a simple concept problem in the corner of the textbook.
Basic stuff, really—but my head was an empty slate.
“Uh… that’s… 1…?”
“Ha, this bitch. How do you screw up even this?”
“Ah…”
“Wrong, so what now? Strip, or quit?”
Biting my lip hard at Kang Hye-won’s voice,
all that remained on my body was a white bra and panties sticky with arousal.
Lose these, and it’d be exactly like I’d imagined.
But I couldn’t refuse.
The memories of obeying as their pet compelled me to follow the rules we’d set as friends.
“I’ll strip…. It’s the rule.”
“Good, hurry up then.”
Slowly, so slowly, I reached behind my back and unhooked my bra.
With a soft pop, the fabric constricting my breasts dropped to the floor.
Then, with trembling hands, I gripped my panties and dragged them down past my thighs.
A long string of slick stretched out, and a musky, fishy scent flooded the room.
Finally, utterly naked without a stitch on, a moan slipped from my lips unbidden.
I’d done it.
Just like at the motel, I was exposed in my cheap, slutty nakedness before them again.
“Wow, our Seojin’s totally stripped now?”
“Ngh….”
“Why’d you keep messing up? Like you wanted to get naked.”
“Hik…!?”
Seo Ye-eun’s eyes sparkled with amusement as she scanned my naked body up and down.
Every spot her blatant gaze touched burned like fire on my skin.
“But what now? No more clothes to strip.”
“Hng, nngh….”
“Screw up again here, and the penalty’s way bigger than stripping. You okay with that?”
“Hik?!”
A bigger penalty.
Just those words made my body shudder involuntarily.
With the mood like this—and coming from Seo Ye-eun—whatever punishment awaited wouldn’t be easy.
Should I beg now? Say I’m sorry, that this is enough, please stop?
Any rational thinking screamed to tuck tail and run.
But the words that spilled from my mouth were something totally insane.
“L-let’s keep going. It’s all or nothing now… just get ‘em right…!”
“Oho…. That confident?”
“Yeah. I am…”
No, honestly, I wasn’t.
Any concepts in my head had flown out long ago—how could I solve anything?
The real reason I insisted on continuing was simple.
I was curious what that bigger penalty would be now that I was naked—what horrors and pleasures it’d bring.
“Alright? Special problem incoming then?”
“Ngh…!?”
“Nail this, and I’ll give your underwear back. Miss, and you get punished. Got it?”
“Nng… bring it.”
“Good, Hye-won, start us off.”
“Roger. Special problem time.”
Kang Hye-won smirked and read the next one.
As expected for a special, it was tricky and tough.
Even in a normal game, I might’ve second-guessed and blown it.
But difficulty didn’t matter now.
“The answer is…”
Gripping the table with shaking hands, I spat out the first random number that popped into my head.
“3…. It’s 3!”
“Wrong.”
“Huuuk….”
Close, or thank god.
If I’d guessed right by luck, it would’ve ended anticlimactically.
But now I’d blown it on purpose—time for punishment.
Good, let’s see what this is.
If it’s too much, I’ll concede and go back to normal studying.
I rationalized it to myself and squeezed my eyes shut.
“Wrong, huh? No more clothes for our Seojin, so time to take your penalty with your body?”
“Hngggh…!”
“Ready, Seojin?”
I opened my eyes and nodded faintly.
Seo Ye-eun rose slowly from her seat with a satisfied smile.
She approached my frozen naked form, leaned in from behind the chair, and breathed hot against my ear.
“The first penalty our Seojin gets is…”
“Ngh….”
What would it be?
Roughly groping my breasts and tormenting my nipples?
Or straight to my pussy, ravaging me till I came?
Not knowing made my heart thunder, my pussy growing even wetter.
She looked at my eager, swollen anticipation and chuckled.
“Sit in the thinking chair and wait without doing a thing.”
“…Huh?”
A punishment I’d never seen coming.
