Good Girl's Reward
You're my pet now. Good girl.
Those short, sweet words snapped the last thread of reason I'd been clinging to in my mind.
I wanted my reward. Now.
The shame that had filled my heart just moments ago melted away like snow, replaced by a thick, vulgar craving.
"R-reward...? You're gonna give me a reward...?"
"Of course~. My good little puppy deserves one."
"R-right... hnn! S-stop thaaat...!"
Just minutes earlier, I'd been eagerly licking and sucking Ye-eun Seo's pussy with my tongue, my face drenched in her juices.
Anyone who saw it—hell, even I knew—it was the act of a mindless bitch in heat.
And now, for doing it so perfectly, I was getting a reward. It was as good as admitting I'd devolved into a beast.
But I didn't hesitate long.
"That's right, my puppy wanted her reward, didn't she?"
"Hnnngh..."
"Come up slowly. No need to rush—I'll give you everything."
In the end, I let her sweet command draw me in. Careful not to spill a drop of anticipation, I crawled onto the bed for my prize.
It was all over anyway.
I'd had chances to say the safe word but kept my mouth shut. I'd thrown myself into beastly acts without a second thought.
What would refusing Ye-eun Seo's reward change now?
Nothing.
Like they say, giving in makes it easier. I just wanted to surrender to this insane pleasure and feel good.
I settled obediently on the bed, sitting and waiting for her to toy with my body.
"Good girl, puppy. You listened so well—truly excellent~."
"Nnngh..."
"You worked so hard today. Making your owner this happy? I'll give you the best reward I can."
"Haa... P-please, reward me... Make me cuuum...♥"
Vulgar pleas for my owner's reward spilled from my lips, unfiltered.
Ye-eun let out a satisfied chuckle, then slipped behind me, pulling my body into a deep embrace.
Her soft breasts and warm body heat pressed against my bare back.
She was wearing clothes, but it felt like skin on skin—goosebumps erupted all over me.
She ground her tits into my back, squish squish, etching that dizzying sensation deep into me.
- Squeeze!
"Hnnngh?!"
Then her arms shot forward to my chest.
Ye-eun's fingers gently enveloped my swollen, soft breasts.
It wasn't just rough kneading. She caressed the undersides softly, building layers of dull pleasure until I held my breath—then she pinched and twisted my sensitive nipples in a sneak attack.
"Hnn! Y-Ye-eunaaah...! Hnng! N-not there, like thaaat... Aaaahn!"
"Shhh... Be a good girl. Relax~."
"Hnn, ngh... Nnngaaah!"
Not sharp pain, not boring rubs—a perfect tightrope walk. Teasing just enough to feel good, but never letting it tip over. My body trembled at her infuriating touch.
It felt so good. I was going insane.
Please, please touch me for real...
But her hands tormented my breasts right up to the edge, where something hot threatened to burst inside.
"Getting this worked up from just your tits. Seo-jin, you've got real talent as a girl."
"Haa... Hnnngh... M-more, moreee...!"
"Ah, no."
Ye-eun brought her lips close to my ear, whispering in a mocking tone.
"Right now, you're my cute little puppy. Should I say you've got talent as a bitch instead?"
"Th-that... Hnn?! Haaaang!"
"Hehe, a bitch wants something even better, so I'll put in extra effort~."
Bitch. Bitch in heat. Those vulgar words drilled into my ears, melting my brain white.
I should deny it, get angry—but instead, I gaped my mouth like an animal, drool dripping as I savored the humiliation.
No, it felt better.
Having my tits sloppily played with while mocked as a bitch pushed me to a far dizzier cliff's edge.
If only I could cum like this...
"Just tits would bore you, right? Want me to pamper somewhere else?"
"Hnn... Nnngh?!"
"Here, feel this~."
The hand teasing my left breast slid slowly downward.
My right nipple still pinched, her fingers trailed over my sternum and belly.
Finally, they reached my lower abdomen—just above my pussy, that strange, sensitive spot that felt full yet emptily alien compared to my male days.
Ye-eun's fingers pressed and rubbed there firmly.
"Huiiih!! Th-there...!"
"This is where girls are most sensitive. Right where your womb is."
"Haa, yeah... R-really...?"
"Especially on those days—super sensitive and achy. All girls go into heat then~."
"Wh-where's thaaat... Hnnnngh?!"
"But my puppy's always in heat like a bitch, so rubbing here should be fine, right?"
She was right.
Just her pressing and stroking my lower belly had my pussy between my legs twitching wildly, gushing juices like crazy.
Feels so good, I'm losing it...♡
Every stroke sent chills racing up my spine.
Every firm press above my pussy felt like something hot searing inside.
Not even touching it directly—just pressing my belly.
This alone was driving me half-mad.
If that hand slid down to my sopping wetness...
"Feels good, huh?"
"N-nngh!! Y-yes, so good...!"
"Hehe, good. Then let's go somewhere even better."
Already half-gone, eyes glazed, I just nodded and panted.
Her hand tormenting my belly shifted lower.
Finally, finally touching me there?
But her hand grazed my sensitive spot teasingly and went much further back—to the filthy hole stuffed with the heavy tail plug.
"Eek...!"
"You know this can feel good too, right?"
"Wh-what're you taaalking...! Hnyaang?!"
"How's that? Feel it?"
Her fingertips tapped the cold metal base plugging my ass tight.
Each jiggle of the heavy weight inside stirred my guts with bizarre, unfamiliar sensations—every hair on my body stood on end.
How could this feel good?
I couldn't understand, didn't want to—but instinctively, I knew with every touch.
This spot could feel good, just like she said.
More weird pleasure than discomfort or pain surged in with every prod.
"Oh, by the way, the tail I put in my puppy today is just a tiny beginner one."
"Hnnngh...! Ngh..."
"Most beginners can't take it easily, but Seo-jin handled it so well?"
Ye-eun stroked the fur at the plug's end, murmuring low.
"Once you're trained into a perfect bitch... I'll get you a much thicker, better tail~."
"Ah... Haa... N-ngh..."
This chunk alone felt like it was crushing my insides—something even bigger in this hole?
I couldn't imagine how much further I'd fall.
Terror flooded me, but my instincts eagerly pictured that horrific moment, blooming with chilling anticipation.
No, I shouldn't look forward to this...
I wanted to scold myself, steady my heart—but only vulgar moans escaped my lips.
"Now, time for my bitch's favorite real reward?"
"Hnn...?"
"Ready?"
My trembling body nodded on instinct, and Ye-eun's fingers moved.
Fiddling with the tail in my ass, they turned upward, sliding between my legs.
Her fingertips touched the entrance of my pussy, soaked and throbbing from the wait.
"Eek...!"
"Oh my. No need to train this spot separately."
"Haa... Hnnngh..."
"It's gaping wide, drooling for owner's fingers."
"N-not like thaaat..."
- Squish...!
"Hiyaaaang...!!"
"It is~. You're not being honest."
With her mocking whisper, her slick middle finger plunged deep into my wet pussy.
Electric pleasure shot up my spine to my brain in an instant.
Just one finger, and my walls clenched madly, gripping it tight.
"Haaang! Aaang! Y-Ye-eunaaa...! Hn, aa! S-so good...! There, hiaaah!"
"Amazing. Puppy, I can feel your insides pulsing around my finger."
"M-more, shove deeeeper...! Ahaa?! Haaaang...!!"
Her right hand flicked and pinched my nipple, while her left roughly scraped the most sensitive spot inside—a perfect two-pronged assault.
Amid the furious caresses, the last remnants of human reason in my head—Lee Seo-jin's—evaporated completely.
Shame? Humiliation? Gone without a trace.
Only explosive pleasure and the twisted, sweet depravity of being a bitch receiving her owner's touch ruled me.
- Squish! Squelch! Squish!
"A-ah! Gonna... gonna cuuum...! Hn! Haaaang♥"
"Already? I haven't even really started."
"C-cumming...! Let me cuuum...♥"
"Got it~. As you wish."
"Hnn... Haaangh!"
With that lazy reply, two fingers thrust in without mercy.
Unlike her soft voice, her movements inside were rough, merciless.
Squelching filled the room, white light flooding my vision.
Feels so good...
I wanna cum like a beast♡
- Squish, squelch... Squelch...!
"Nngh...! C-cuuu...♥ Eek! Cumminggg..."
"Gonna cum?"
"Y-yes♥ I-I wanna cuuum...♥"
"Your tongue's all mush~. Alright, as you want."
- Press...!
"Hiiik?!"
"Cum, you bitch."
Her cool command to cum—and her fingers stabbed mercilessly into the deepest, tenderest spot inside.
That vulnerable place that usually just poked faintly.
Ravaged by rough fingers, my back arched like a bow, vision flashing white.
"Hiyaaaaaang♥"
"Wow, what a slutty scream~."
"Huu, ngh... Hnnngh...?!"
I finally hit my limit, howling like a beast as I plummeted into orgasmic bliss.
And right then—
- Spluuurt...!
"Hiyaaaaang...!!"
An unbelievable torrent of clear fluid erupted from between my legs like a fountain, soaking the bedsheets.
My first overwhelming, violent climax left me shuddering violently, drool and tears streaming.
My body went limp.
I slumped into Ye-eun's arms, spent.
"Haa... Haa... Hnnngh..."
"My pretty bitch squirted so hard."
"Hnn... Nngh..."
"Now, lift your head and look in front."
She kissed my sweaty forehead contentedly, then gently cupped my cheek, turning my face forward.
My hazy, unfocused gaze met the full-length mirror across from the bed.
Facing my naked reflection, my breath caught.

Ye-eun in her pink pajama shirt, hugging me tight from behind, a satisfied, sultry smile on her lips.
And me in her arms, legs spread wide.
Black puppy ears on my bobbed hair, a crude leather collar around my neck, thick furry tail protruding from my ass.
My nipples erect and flushed red, pussy gaping between spread legs, juices splattered messily on my thighs and sheets.
But the most shocking was my face.
Smeared with tears and drool, tongue lolling out like a beast, mouth agape in a dazed pant. No trace of humanity—a perfect bitch in heat captured vividly in the mirror.
"See? You're my perfect pet now, Seo-jin."
"Nnngh..."
No.
I'm Lee Seo-jin, an ordinary guy studying for retakes to get into university.
I'm not some vulgar pet wagging her tail for rewards.
Just my gender changed recently—I'm the same person otherwise. I wanted to shout it.
But the mirror showed an undeniable vulgar bitch.
"You worked hard with training today, Seo-jin. Now rest well."
"Haa... Nngh..."
"Tired, right? Close your eyes and sleep."
Ah, it's finally over.
A strange relief from total surrender mixed with post-orgasm languor washed over me.
Too broken to even think of resisting, I leaned deep into my tamer's arms and slowly closed my eyes.
