Hellish Yet Sweet Study Days
The hellish yet sweet weekend of an ordinary cram student's life had passed, and I was back to my monotonous, hamster-wheel routine.
Waking up early in the morning to head to the academy, sitting at my desk late into the night listening to lectures and solving problems—the dull, dry existence of a typical retaker.
On the surface, it looked no different from before, but something inside me had flipped completely since that day.
"...Boring."
The first change was that I couldn't satisfy myself with ordinary stimulation anymore.
Before, I'd have fired up a game under the pretense of relieving study stress, but now those games felt utterly unexciting.
Even the lewd illustrations I'd secretly search for late at night with my door locked were the same.
After becoming a girl, only yuri ones had caught my eye anyway, but now even those barely registered.
Okay, fine, that much I could accept.
It was actually helpful for focusing on studying, so a good change, right?
The problem came when I ran into those two delinquent girls at the academy and chatted with them.
"Seojin, did you sleep well last night too? You didn't stay up late doing something weird, did you?"
"Y-yeah... I slept great."
"Good. Sleep's the most important thing when you're studying. That way, we can grind hard today and all get into the college we want together~."
During break time, Seo Ye-eun approached my desk with a gentle smile and sweet words.
To anyone listening, it sounded like perfectly wholesome encouragement to cheer on a friend and boost her spirits.
But my brain twisted those innocent words into something utterly vulgar on its own.
'Our little bitch, you gotta become the smart puppy your owner wants and do all your pretty tricks, right? Go on, wag that tail.'
My mental auto-translator turned her kind cheer into her owner's sweet command.
The moment I heard it, my lower belly tingled, and I even felt a phantom tail wagging furiously behind me.
Owner's praising me. Owner wants a smart puppy.
An inexplicable passion surged up inside me.
"You really slept properly, right? You've been spacing out a lot lately."
"Eek?! N-no... I haven't been spacing out that much."
"Good. If your scores drop below ours and you can't get into college with us, you're dead, got it?"
Then Kang Hye-won, leaning in from the side, playfully tapped my desk and jabbed at me.
It was the kind of teasing scolding you'd expect between close friends, but in my head, it came out completely different.
'If you fail the entrance exam and turn into a useless mutt, I'll really whip your ass raw. Do it right, okay?'
I could almost hear the crack of the leather paddle slicing through the air over her voice.
A chill ran down my spine, goosebumps prickling as my inner thighs quivered uncontrollably.
The terror that if my grades really slipped, I'd face that merciless punishment.
And the dizzying anticipation of the overwhelming pleasure that came after the pain.
They crashed over me at once.
"Seojin will do great. Don't be so harsh, Hye-won."
"Yeah, probably. Seojin's a good friend, right?"
"Y-yeah...! Yeah..."
The two of them left me with those strangely loaded words before switching to another topic.
As their somewhat burdensome attention drifted away, I let out a sigh of relief.
Becoming their pet had left this vulgar translator in my brain.
That alone was tough, but the real trouble started after parting ways with them and getting home.
"...Yeah, gotta do what needs doing."
After academy ended, I headed straight to my room, locked the door, and spread out what I'd study that night on my desk. Then I sighed deeply.
Normally, my hand would reach for a pen to start studying, but instead, it went not to the pen on the desk—but to my pussy underneath it.

"Ah! Hn, ahh...!"
With the room lights off, relying only on the desk lamp, I slumped sideways in my chair.
One hand clutched my concept review notebook tight; the other slipped into my pajama pants to rub my secret spot.
Studying while masturbating.
That was the massive, vulgar change that had taken over my life since that day.
"Can't get in together... I'll die...♥"
Kang Hye-won's chilling voice from earlier and Seo Ye-eun's gentle praise echoed back and forth in my head.
The sensation of being naked except for my collar, getting my ass spanked.
Remembering that beastly moment of pissing on the puppy pad while crying from shame synergized massively with their voices.
"Hngg...! W-woof, woof woof...! T-together... we'll go... togeeeether...♥"
In the end, biting my lip hard, I arched my back from just my fingers' stimulation and those twisted translations of everyday chat—cumming hard and clean.
Not as intense as that time, with no squirting, but enough to release the built-up lust. A perfect moderate climax.
I slumped in the chair, panting, body limp.
Reality hit hard at the fact I'd jerked off while barking like a dog in my room, but a weird feeling washed over me too.
After shuddering through orgasm, my fatigue vanished, replaced by a bizarre surge of study energy.
"Haa... haa... This isn't... a normal cram student's life..."
I sighed, pulling my sticky fingers from my pussy.
The desire for praise and instinct to avoid harsh punishment.
That vulgar motivation had turned me into a perfect study machine.
'Our Seojin has to get into the same college as her owners to get all the pets, right? We'll love you up tons~.'
'If you're thinking of tanking on purpose to escape, you're dead? Do it right, got it?'
"Eek... Y-yeah, I get it. If I study hard... it'll be fine..."
Their voices echoed again in my head, so I wiped my pussy roughly and sat properly.
Gottta focus on studying when the energy hits.
That way, my heated body could cool, and their strengthening voices in my mind would quiet down.
And so, days passed in this bizarre, vulgar routine.
Finally, the day of the June evaluation mock exam arrived—the first hurdle for retakers, deciding our fates ahead.
"I can do it. Lee Seojin... you can do this...!"
I psyched myself up, even muttering aloud as I took the test.
Sure, I spent time on vulgar masturbation before studying, but I'd cut gaming and slacking even more, so net study time increased.
Plus, post-orgasm focus sharpened weirdly, brain working better—efficiency skyrocketed.
At this rate, way better than last time...!
The June mock wrapped amid tension and strange excitement.
Seo Ye-eun, Kang Hye-won, and I finished all tests and gathered to check preliminary scores.
"Hmm~. Mine came out as expected."
"Yeah? Ugh... Inquiry went well, but why'd English suck?"
"You're a bit weak in English, Hye-won~. Wasn't it the same last time?"
"Yeah... Well, just need to invest more. Oh, what about Seojin?"
We three spread our answer sheets, grading them.
Seo Ye-eun seemed to have nailed expectations; Kang Hye-won had hits and misses.
My turn now.
I carefully checked and graded my sheet.
And the result was...
"What...? D-did I really score this high?"
"Seojin~! Amazing. Your scores jumped like this!"
"Ooh, Lee Seojin. Not bad."
Even better than I'd hoped—massive improvement.
Korean, math, English.
All top-grade 1s in the big three subjects.
Pouring beast-like into studying outside eating/sleeping to meet my owners' expectations paid off.
Tears welled up from emotion I couldn't contain.
"Wow, our Seojin is incredible! All 1s in Korean, English, math?"
"Hehe... No, just lucky."
"Luck? I know how hard you've worked. Great job—if you keep this up, that college is a free pass."
Seo Ye-eun beamed at my score sheet, gently petting my head.
Good girl, our puppy. Such a smart one.
My brain translator fed me sweet hallucinations from her touch.
Feeling good, I unwittingly nuzzled her hand, wagging my tail inside.
But the sweet praise didn't last.
Kang Hye-won flipped to the back page of my sheet, frowning coldly.
"Hey, Lee Seojin. Korean, English, math are great, but what's with inquiry?"
"Huh...? In-inquiry...?"
"Yeah, inquiry. All 1s elsewhere, but 3rd grade here? Were you daydreaming during those?"
"N-no...! I studied hard, but so much to memorize, got a bit mixed up... And I always got 3rd in inquiry anyway..."
"No excuses. 1s everywhere else makes that 3rd look bad."
She tapped the sheet accusingly; I shrank like a whipped puppy, making excuses.
Useless mutt. Bringing home scores like this? On your belly. Now.
Her icy glare seemed to lift the leather paddle.
Fear hit, but so did the tingle low in my belly, tension building between my thighs.
Thankfully, Seo Ye-eun smoothed it over softly.
"Don't be too hard~. 1s in the big three is huge for Seojin."
"Ye-eun..."
"Still, getting 3rd in inquiry when you could do better is a shame. Right?"
"Y-yeah..."
"Good thing inquiry improves fast, unlike the big three. You know that, Seojin~?"
I nodded.
Whatever miracle hit, 1s in notoriously tough Korean/English/math was massive.
Inquiry? Comparatively easy to boost short-term.
Just study while hearing their voices like now.
- Drip...♥
Thinking that, my secret spot felt wet.
"Got it. I'll focus on inquiry from now on."
"Good~. But planning to study alone?"
"Huh...?"
"Hye-won's an inquiry monster. Same subjects as you—her help could boost you faster, no?"
True, she'd nailed 1s in inquiry again. Despite retaking over botched Korean or whatever.
"Yeah, probably."
"Right? How about a study group?"
"Study group?"
"Yeah! She'll share tips! Studying together might help focus more?"
A study group?
Glancing over, Kang Hye-won smirked casually.
Something felt off, ominous.
Instinct screamed danger, but I shoved it down.
Worse than before? Nah.
And this was about studying, not turning me into a bitch.
Should be fine.
"Yeah, let's. Studying together will help for sure."
"Knew you'd say that, Seojin. Study group it is!"
I just nodded at her beaming excitement.
Could I even handle a study group properly?
Lucky if I didn't get horny alone and just masturbate.
Whatever, it's just studying. It'll be fine.
That's what I told myself.
I shouldn't have.
