The Good Bitch's Oath
"I'll be a good little bitch who spreads her pussy and wags her tail just like you order... ♥" Kang Hye-won yanked roughly on my leash, dragging me toward the wide bed in the corner of the room.
"Get up there."
"Hngh...!"
"Hurry up, get on it already?"
When I hesitated in fear, Kang Hye-won snatched the leash and shoved me onto the bed.
I couldn't resist that forceful push and tumbled onto the bed.
My upper body flopped face-down onto the soft mattress, while my lower half stayed on my knees on the floor, ass thrust high in a humiliating pose.
Kang Hye-won gave my taut leash a short tug, tying it securely to the bedpost, then pulled out leather cuffs and bound my wrists to the leash.
"You can't move when you're getting punished, so I have to fix you in place nice and tight."
"Hii... W-Woof! Woof!!"
"Aww, so noisy. Maybe I should just gag that mouth of yours."
"Hng...?"
With that, Kang Hye-won pulled out a thick rod gag with black leather straps from somewhere.
Just seeing that vicious thing that had muffled my mouth earlier, preventing me from saying the safe word freely, made my body tremble.
If that goes back in my mouth, even if I miraculously remember the safe word, I won't be able to say it.
"Open your mouth."
"N-No, hnggh... I d-don't wanna... Mmphh?!"
I shook my head in refusal, but Kang Hye-won grabbed my jaw roughly and forced my mouth open.
She shoved the cold, hard silicone rod deep into my mouth and pulled the leather straps tight behind my head, buckling it securely.
Now I couldn't close or open my mouth freely around the thick rod.
Drool spilled from the gaps in my forcibly parted lips, soaking the bedsheet.
"Mmph...! Mmmph...!"
"There. Now you're finally in the right state for your punishment."
"Hnnnggh!!"
I was completely bound, unable to even run away, and with my mouth stuffed, I couldn't scream properly.
On top of that, my bare ass and the hideous tail plug wedged between were thrust defenselessly into the air.
No matter what punishment came, I couldn't refuse or escape.
I'd truly become a good little bitch who could only take her punishment obediently.
"Where do you get off trying to trick your owner? Did you think a pathetic bitch like you could scheme and we wouldn't notice?"
"Hng, mmph...! Mph!"
- SMACK!
"Hiiiggh...!!"
Kang Hye-won's leather paddle sliced through the air, mercilessly striking my ass and thighs.
The sharp pain felt like my flesh was ripping apart, stars bursting before my eyes.
With the gag crammed in my mouth, I couldn't even scream properly, just writhing and trembling against the cuffs binding my hands.
"Trying to pretend you didn't piss on the floor after failing to hit the toilet? How utterly shameless."
"Hngh...! Hnnngh...."
- CRACK!
"Mmmphh!! Mph, hnnngh!"
"A bitch like you only learns when she's beaten."
"Brrngh, mph...! Hnggh...."
But as the merciless whipping continued, a strange change started stirring inside me.
Each time Kang Hye-won's paddle slammed into my ass, the heavy impact traveled through the deeply embedded metal tail plug, transmitting straight to my inner walls.
The pressure in my asshole seeped beyond to tease my pussy subtly.
It hurt. It hurt so much I thought I'd go mad.
Yet at the tail end of that excruciating pain rose a bizarre, sticky pleasure that shot tingling up my spine.
"Oh my, Hye-won. Look at her shaking her ass even while getting hit."
"For real? Hey, is that from the pain, or are you getting off on the spanking? Pussy juice is dripping everywhere."
"Hiiik...! Mph, hnnngh...!"
"Ugh, this horny bitch gets turned on even from ass spankings. Totally hopeless."
"Brrngh...."
Kang Hye-won was right in her mocking words.
Even as my ass swelled red and raw from the beatings, hot, sticky fluid gushed from the slit below, trickling down my thighs to drip onto the floor.
My reason screamed in agony from the pain and humiliation, but my body—fully corrupted into a bitch's—accepted even my owner's punishment as pleasure, heating up like an animal in heat.
This is wrong.
Why has my body become like this... ♡
"So you're brazenly feeling good even while your owner punishes you?"
- SMACK! SQUELCH!
"Haahng! Mph, hngh...! Mmph!"
"Look at her now, just gushing pussy juice everywhere."
The friction of the paddle slapping flesh and the squelching of the plug against my inner walls filled the room.
My breath came in choked gasps, tears soaking the sheet.
It hurt like hell, it was humiliating and shameful enough to make me want to bite my tongue off.
But at the same time, it felt so good my brain was melting.
In that dizzying sensation where the line between pain and pleasure completely collapsed, I could only moan pitifully, twisting my hips against the bed.
No, if I keep taking this punishment, something's gonna break inside me.
Please, just fuck my pussy and make me feel good instead....
It was around then, as my mind grew hazy in the tangled chaos of pain and pleasure.
"Hye-won, that's enough. Our puppy might actually pass out."
"Hngh, ugh.... Brrngh..."
"Fine, whatever. She's been hit enough that she'll never try scheming again."
With Seo Ye-eun's gentle voice, the leather paddle that had been mercilessly thrashing my ass was finally withdrawn.
I panted raggedly, enduring the burning skin like it was on fire and the lingering tingles deep inside.
Was the punishment over now?
Would the paddle come flying at my ass again?
Trembling in fear and the weird pleasure wrapping my body, that's when Seo Ye-eun climbed onto the bed, unfastened my leash, and gently brushed back my sweat-matted hair.
"Seojin worked so hard taking her punishment~."
"Huu, hnnngh?!"
"Oh, right, I should take this off too."
- Click
"Puhahh...! Haa, haa, hnggh...."
The buckle squeezing the back of my head came undone, and the rod gag filling my mouth was pulled out.
Pent-up breath burst from my aching jaw, and the pooled drool stretched in a long string from my lips to the sheet.
My mouth was free.
If even a shred of reason remained, I would've screamed the safe word I'd been dying to say.
But my mind, thoroughly steeped in pain and pleasure, had no room for rational thought.
"You okay, Seojin?"
"Eut... Ahng... ♥ Huuuh...."
"Sounds like you're just fine~."
Instead, the moment the gag came off, what escaped was a heated moan craving more pleasure.
Seo Ye-eun gently cupped my jaw, meeting my eyes with a soft but chilling voice.
"We punished you because you did well but also messed up. You get that, right?"
"Hngt.... W-Woof...!"
"Got it. I'll make a special exception and let you speak human words this time, so let's hear your resolution."
"Hngh...?"
"Will you trick your owners and scheme again? Or will you be a good puppy who obeys her owners?"
What was I supposed to answer?
If I said I'd keep scheming, the outcome was obvious.
The paddle would come flying at my ass again.
But if I promised to be a good, obedient puppy, I'd never return to the old me.
Ah, no.... I can't... answer....
The only real answer was clear.
The safe word.
She'd even allowed human speech—saying it now would end this roleplay cleanly.
But even in this critical moment, the safe word wouldn't come to mind.
Drawing? Academy? Friend? What was it...? What the hell was it...?
As I just worked my lips in hesitation, the smile lingering on Seo Ye-eun's lips began to fade.
That chilling atmosphere told me instinctively.
I had to decide on an answer fast.
Refuse and take more beatings, or submit here and receive my owner's warm touch and reward.
The right choice was painfully obvious.
"Hngh.... Y-Yes.... I'll obey...."
"Oh? How exactly will you obey?"
"N-No more scheming... I'll do whatever my owners... haa... order, spreading my pussy and wagging my tail... like a good little bitch... ♥"
It was an unbelievably beastly, vulgar oath even for me to utter from my own mouth.
How could any normal person say something like that?
Hearing it, Kang Hye-won cackled in disbelief, while Seo Ye-eun flashed a spine-chillingly satisfied smile.
"Oh my, our puppy. Once her mouth's free, she picks the prettiest words~."
"Haa... Hng, hngt...."
"Good. Since our good puppy promised to behave, her owner has to reward her accordingly, right?"
Seo Ye-eun stroked my cheek once, then turned toward the bedside table.
Punishment over—now the reward.
My body, which had just begged to have its pussy fucked, reacted instantly to those sweet words, gushing more fluid.
The moment I thought I'd finally taste sweet pleasure, wiggling my ass like a wagging tail—
- Slide
The sound of the table drawer opening, and Seo Ye-eun approached with something in hand.
The instant I saw what she held, confusion clouded my eyes.
"Hngh...?"
"Now, shall we give our puppy this as a treat~?"
It was a U-shaped toy, its shaft split into two prongs unlike a regular vibrator.
Anyone could see it was meant for two holes.
But with my puppy tail plug blocking my ass, the only spot available was my pussy.
As if reading my confusion, Seo Ye-eun smiled meaningfully and sat right beside me.
"You've been so good today, Seojin. So I'll end your bitch training lesson with this reward."
"Eut...?"
"Meaning, this tail that helped make you such a perfect bitch..."
Her hand gripped the tail plug firmly embedded in my ass.

"...can come out now, right?"
"Hii...?"
