Training Complete
My little sister squatted down and looked at me from above.
It felt like she was announcing the hierarchy that would define everything from this moment on.
My heart pounded as I exposed my naked body to her. Once the dam had broken, reason flooded out without end, wrecking everything in its path. Then one particular place entered my field of vision.
Between my sister's legs.
The most secret, deepest place. The spot where her panties would be.
The moment that thought formed, my cock twitched and started to swell.
She edged a little closer and locked eyes with me. Brushing her glossy hair aside, she spoke.
"Getting turned on showing your big sister your naked body, puppy?"
Twitch♥
She reached down and put her hand on my cock. With just her thumb and index finger, she pinched the shaft already slick with cum. At that cool, commanding touch, my cock throbbed helplessly.
I looked at her hand — it was so pale and delicate that my face flushed before I could stop it.
"Does it feel like it's going to get hard if I keep touching it?"
"Hic…"
Throb throb♥
My sister fixed me with a steady stare. That haughty gaze made my whole body want to flinch. There was a superiority in her eyes that could have gotten me hard from a look alone.
"No. Don't get hard♥ No erections allowed♥"
Twitch twitch♥
She casually swung my cock from side to side like she was playing with a sausage. The root of it rolled with the motion, and it felt like my prostate was being wrenched along with it. Being forbidden so contemptuously only piled on a strange, mounting excitement.
Defeated and surrendering to nothing more than two fingers. That moment of submission felt so good it threatened to become a habit.
My sister picked her panties up off the floor and pressed them to my face.
"Did my scent get you hard? Want to sniff them like before?"
I swallowed hard. I couldn't bring myself to answer. She spoke with casual indifference.
"You asked me to raise you as a puppy. I'll take responsibility."
"…Y-yeah. I want you to."
At my words, she immediately clamped the panties over my nose. The instant I reflexively tried to inhale—
"Wait♥ Don't sniff. Hold it. Forbidden♥"
My body went rigid. The way she spoke was exactly like someone training a dog. I stopped everything — blinking, breathing — and just rolled my eyes.
A few seconds later, she spoke with evident satisfaction.
"Good. Now you can smell as much as you want. Sniff all you like."
Sniff sniff♡
It was strange. An unnervingly lewd scent flooded my nasal cavity. Originally I had only sniffed my sister's panties so I could lick Park Seoh-ah's breasts. Now just the smell of my sister's panties was getting me wildly aroused. Just burying my nose in them, just breathing in her scent, was enough to drown me in lust.
"I told you not to get hard, and look at you standing straight up… Do you like it that much? Want to cum in my hand?"
"I want to cum… I want to cum in your hand."
She pinched my cock between two fingers and smiled. Confidence poured off her — the certainty that she could crush someone like me in an instant.
"You can't. No cumming♥ Wait♥ You can hold it, right?"
"Y-yeah…"
I huffed through my nose and forced the urge down. But my answer meant nothing — precum welled up and I nearly came anyway.
She stopped her hand and asked,
"Is it hard to hold back because the little sister you always wanted to fuck is touching you?"
I had never once thought about fucking her.
"Does it turn you on that your sister is treating you like a dog?"
Twitch twitch♥
She gently toyed with my bangs. For some reason I couldn't look her straight in the eye.
"You really do want to be a puppy, huh. Did you want me to baby you?"
My lips parted on their own and a ragged breath slipped out.
"Haaah…"
"Or did you want to shove this cute little cock into me? Did you want to get your sister pregnant?"
"Haaah…"
Pinch♥ Pinch♥
"Puppy…♥ You have to answer. Answer Chaeeun♥"
"Ah…♡"
Park Seoh-ah was gently chewing on my ear. With delicate fingers she tormented my nipples. Already teetering on the edge of reason from my sister alone, my mind went hazy at once.
When my sister spun my cock in a circle, my spine jolted. She looked me dead in the eyes.
"You have to answer."
"Y-yes, yesh♡"
She laughed and stroked my head.
"Yes to what? Did you want to be a puppy? Or did you want to get me pregnant?"
She kept swinging my cock carelessly left and right. Park Seoh-ah pinched and twisted my nipples.
"B-both… I want to be a puppy and fuck you…"
"Then should we let you cum nice and good right now? Should you finish from just two fingers?"
Flare flare♥
My nostrils flared with excitement. My sister formed a ring with her fingers.
"Shove it into this handpussy and cum. I'll give you everything you want."
"…"
"Pant like a dog and knock up my handpussy. Cum a defeat-orgasm for your little sister♥"
The handpussy wrapped around my cock. My hips jerked on their own, desperate to thrust into it.
"You can move. You've got to dump a load deep in your sister's pussy."
I hesitated, breathing hard, until Park Seoh-ah whispered,
"Master will help you♥ Just lift your hips and thrust like this♥"
Guided by her hands, I rocked my hips. Friction against the hole she'd made with her fingers.
Twitch twitch♥
My brain sparked. One single stroke and I already felt like I was going to cum.
"That's it. Keep going just like that."
My sister tilted her head with a smile, looking for all the world like she was praising a real puppy.
"Hm…? Already about to cum? Does sister's handpussy feel that good?"
She wiggled the handpussy as she spoke.
"Going to cum the second you put it in? Can't hold it?"
"I'm going to cum… I-I'm gonna cum."
"You can cum. Cum. Dump it in your sister♥ Oppa's a puppy now, so it's okay to cum♥"
"Hek♡"
My sister's handpussy stroked down the shaft and settled at the root. I couldn't tell whether I was thrusting or she was moving. In that state, I fired.
Gush gush♥
My head went blank and the world swam. It felt like I was pumping cum into something deep.
"Heehee. Feel better? Sister's handpussy is going to get pregnant♥"
Twitch twitch twitch♥
"If you get pregnant, thass… not allowed…"
"Duuummy. Your brain turned into a puppy's too♥ How are you going to get pregnant from a hand."
"Ah…?"
You… can't get pregnant from that?
Park Seoh-ah wrapped her arms tight around me from behind.
"Is our puppy happy? You got to be Chaeeun's dog and fuck a pussy."
Being held felt strange. Being hugged as a puppy.
"Happy?"
"I'm happy…"
"Pfft."
Park Seoh-ah laughed brightly and stood up. The moment her full breasts left my back, a hollow emptiness settled in. Without thinking, I dropped onto all fours like a dog.
Smoothing her clothes, Park Seoh-ah said,
"Well? You're a complete dog now. Only took two days."
"……"
"At this rate we can take him with us in three days, right?"
"…How did you do it?"
At my sister's question, Park Seoh-ah paused. She looked at me, then shoved her firm ass into my face. She pressed it down hard, toppled me onto the floor, and sat on me completely.
A thick, damp sweat-scent flooded out as my vision and airways were sealed shut. The same sense of defeat and surrender I'd felt under her feet washed over me — only the pressure was far more intense, the helplessness far more vivid.
At the same time, my cock started reclaiming its hardness. It was exhausted from cumming too many times today. My stamina was spent, past its limit — and yet it got hard without fail.
Park Seoh-ah's sunny voice floated down.
"How? Because our puppy is a total masochist."
"…"
"A maso who's desperate to submit to women♥ A maso who has dirty fantasies about his little sister♥"
Throb♥
"Your cock keeps twitching♥ You're getting off on this♥"
"Hahk♡"
"You're getting off on losing to an ass♥"
Throb♥
"You must be a born masochist. Your body already felt developed."
"Developed?"
"Like someone already trained your body? But you said you've never dated a girl. Guess you were just born a maso. A puppy from the day you were born."
"…"
"Should we name our puppy now? Want me to pick, or do you want to?"
"…I'll pick."
My sister said,
"How about Cookie?"
"I like it, it's cute! Wait — did you name him after that Cookie over there?"
"Who cares about a name. If you don't like it, you pick one."
"Hehe, no. I like it too. Does our Cookie like it?"
Park Seoh-ah's body tilted, and a shiver-inducing breath ghosted over my cock.
"Hooo♥ If you like the name Cookie, wiggle for me♥"
Wiggle wiggle♥
"Mm♥ He likes it a lot♥ Cookie likes everything Master does, right?"
Wiggle wiggle♥
"Ah♥ What am I going to do with this maso♥ You're too easy. So cute♥"
Park Seoh-ah lifted her hips and stood. I must have been on the verge of suffocating — air rushed into me all at once. My lungs seized and I coughed. It had clearly been dangerous, and yet all I felt was regret that it was over.
"Cookie, stand up♥"
At her command I dropped onto all fours. Park Seoh-ah stroked my head as if I'd done well.
Our eyes met. The upward curve of her smiling eyes was so captivating it made my heart race.
Only…
Was it because I had seen the future? Something about that gaze felt hollow. Empty somewhere, vacant, artificial — like she was wearing a mask. Compared to the eyes I had seen in the future, you could say there was no affection in them at all.
If anything, my sister's haughty gaze seemed to hold more warmth.
Why? Maybe it was just the reverse culture shock of having seen the future. In the future, time had passed — of course more affection would have grown by then.
My sister flicked my cock with a finger.
"From now on, you're absolutely not allowed to cum without Master's permission. No ejaculating. Got it?"
She looked down at me steadily. Captivated by that arrogant stare, my nostrils flared.
"But if you listen to Master well, I'll let you have an orgasm way better than this one."
An orgasm way better than this…
What could possibly feel better than this.
Don't tell me.
"I'm going to give Cookie what he just thought of. I'll let you put it in Master's real pussy."
Twitch♥
"Ah, it twitched. What a dumb dog♥ There's no way Master would ever let a pathetic little dick like this inside her."
She dangled my cock back and forth.
"From now on, Cookie's cock is mine. You're never allowed to use it however you want. Got it?"
Twitch twitch♥
"Y-yes…"
"Cookie, come here."
Park Seoh-ah dropped onto the sofa. I crawled to her as if it were the most natural thing in the world. The moment I reached her feet, she buried my face straight between her legs.
This time, though, what my face sank into was the pussy beneath pure white underwear. While I breathed in the scent of her slightly damp panties, she whispered,
"Master wants to keep babying Cookie forever, but after today we won't be able to see each other much."
I was sniffing that musky scent in a frenzy when her words gradually started to sink in. I looked up at her blankly.
"Don't make that sad face. I'm not abandoning Cookie, so don't worry."
"…"
"It's nothing major… Master has to study. And I have a part-time job. So I just don't have a lot of free time."
"…"
"Master has to get into a good university and land a good job. I have to make a lot of money. That's how I can take care of our Cookie too. You'll understand, right?"
Press♥
She pushed down on the back of my head and squeezed her thighs together. My face mashed against her outer lips and filled with that musky fragrance.
"Master wants to be with Cookie all day. I'm sorry I can't. Okay?"
The weakness in her voice made my heart lurch. I scrambled to open my mouth.
"I… I have money. Please use my money."
"Hm? Cookie's going to give Master money? You're going to give me everything?"
"Yes. Please use my money… I have a lot. In exchange… please baby me a lot."
Press♥
There was no answer, but the pressure on my face intensified. Her skin was so soft it was pure bliss. The feminine scent dominating my nose was something I could never get enough of. The longer my face stayed pressed there, the wetter her pussy became. When I licked the soaked panties, a tingling taste spread across my tongue.
"Does Cookie want to be with Master all day?"
"Yes…"
"Then want to be Master's manager? Master just got cast in a drama."
A drama? So she was trying to become an actress.
"If you become my manager, you can stick with Master all the time and— nn…"
Park Seoh-ah rubbed my face this way and that, as if searching for a good spot. Then she lifted her hips slightly and shoved hard on the back of my head. My face was ground against her from clit to pussy.
"Mm, nn, hhk♥ Like this… we can do dirty stuff all the time♥"
Slurp♥
"If you're my manager, mm♥ you can submit to Master even outside♥ Nnh♥"
Before long, sweet little moans were slipping out between her quickening breaths.
"Hnn… mm. Nn♥ Haa♥ Master, Master's gonna cum♥"
Slurp♥ Slurp♥ Slurp♥
"Nn— haa. Haahk♥ Hnnn♥ Because of Cookie, Master came♥ Hurry up and lick♥"
Heat rose thick from her pussy. I pushed the scant fabric of her panties aside and licked the wetness spilling out. She had hair, so every lick brought pubic hair into my mouth. The sensation was strangely addictive, and my tongue sped up.
"Happy you get to offer Master your money? Mm♥ Nn♥ Ahn♥"
Twitch♥
"Then haahk♥ stick with Master forever just like you wished♥"
Lick lick.
"Just doing Master's dirty work… hahk♥ and staying hard all the time♥"
Twitch twitch♥
Suddenly a seductive sensation wrapped around my cock. My sister had seized it in her grip.
"Wait♥ I said this cock is mine… Don't get hard♥"
My sphincter clenched. I tensed up trying not to tense up. It was useless. The moment she grabbed me, I only got harder.
"Haa. I told you not to get hard."
"I'm sorry…"
"Then you can hold your orgasm. Hold it. Tense your cock."
Twitch♥
I licked her pussy in a frenzy while my sister's commands ruled me completely. Going to the bathroom, eating, sleeping — for three straight days, all day long, I never left their side for a second. Without a moment to collect myself, I was endlessly whispered to and endlessly touched.
And so I was trained.
Park Seoh-ah and my sister's masochist puppy.
