My Girlfriend Is My Master
I lingered outside the front door, hesitating before turning the handle. 9:14 PM.
I tried telling myself that everything was perfectly explainable. Like usual, the meeting had dragged on, the department head had cornered me afterward, and though I hailed a taxi immediately, rush-hour traffic had been brutal. But would it just sound like a string of excuses? A sudden chill of dread seized my chest.
"Pheeew..."
Stay calm. It's my own home—what's there to be afraid of?
I drew a deep breath and unlocked the door. With a heavy metallic click, I pushed it open and saw the warm glow of the lights inside. Before taking off my shoes, I slid open the inner door.
"You're here?"
A low, quiet voice greeted me.
Soyoung was sitting on the living room sofa, reading a book.

She was a voracious reader—enough of one to swap out half the volumes on her bookshelf every month. In all honesty, I found it impressive.
"Yeah."
Yet right now, the suffocating silence between us was nearly unbearable.
Flip. The crisp rustle of her turning a page sounded razor-sharp.
"Come in. What are you doing standing there?"
As I slipped off my shoes, I stole a cautious glance in her direction. She didn't spare me a look. Only when I stepped right up in front of her did she finally shut the book.
"You're late."
No "good work today," no "go change into something comfortable."
"Yeah..."
My voice crawled along the floorboards. Honestly, a small part of me felt aggrieved. Shouldn't you welcome your boyfriend warmly after a grueling day at work? Hearing a blunt interrogation the second I walked through the door grated on me. Yet I didn't dare voice a single complaint.
"Oppa."
I didn't answer right away—or rather, I missed the window to reply. Though we were the same age, she occasionally called me Oppa. Ordinarily I liked hearing it, but right now I had no idea how I was supposed to react.
Slap!
Stars burst across my vision. A delayed, stinging heat flared across my cheek, and a dull ring echoed deep in my ear. She was strong to begin with, and her slaps packed a vicious sting.
"Why are you standing on two feet?"
I scrambled and dropped straight to my knees.
"I'm sorry."
"Your voice."
"I'm sorry!"
With a faint sigh, she rose from the sofa. The soft trickle of the water purifier filtered in from the kitchen. Soon after, the scuff of her slippers returned, carrying a glass of water.
I swallowed dryly, my throat tightening until it felt constricted. I wished she would just say something, anything...
Amid the heavy silence, she slowly glanced up at the living room clock.
"What time were you supposed to be home?"
"Nine o'clock."
"What time is it now?"
"...Nine nineteen."
Another sigh slipped past her lips. My mouth twitched of its own accord.
"The meeting ran long, so—"
Crack!
My head whipped around violently. If I hadn't instinctively caught myself against the floor, I would have tumbled over completely.
"Did I ask you for an excuse?"
"...No, you didn't."
"Then shut up."
"...Yes."
Soyoung sat back down and reopened her book. She idly checked her phone, sipped her water, flitting from one small distraction to another rather than focusing on any single thing. That indifferent restlessness frayed my nerves even more.
"Choco."
"Yes."
...
An icy stillness descended upon the room.
A shiver ran down my spine. When I lifted my head, she was staring down at me with eyes devoid of any warmth or emotion.

Shit. My senses snapped into place. I hurriedly corrected my answer.
"Woof."
My dry throat produced a raspy, cracked sound.
"Again."
"Woof, woof-woof...!"
"Good boy."
Her tone held no genuine praise, merely a clinical confirmation. Just as I tried to let some of the tension drain from my shoulders—
"Ugh—!"
My neck snapped back. She seized a fistful of my hair and yanked upward, sending a sharp throb across my scalp. With my head forcibly craned back, her pajama-clad figure filled my entire field of view.

"You promised with your own mouth that whenever I call you Choco, you act like a puppy. I don't particularly care for dogs using human speech. If it happens again, I'm going to be very angry."
Frightened though I was, her silhouette commanded my eyes first. Because she was bent forward, the deep valley of her cleavage was laid bare. Her voluptuous breasts hung heavily forward with the posture. The moment I caught sight of the firm nipples poking taut against the fabric of her sleepwear, a tight ache flared in my lower belly.
A slender waist cinched inward before flaring out into wide, curvaceous hips. The dramatic contrast was intoxicating; I couldn't tear my eyes away. Her neatly gathered legs pressed against the fabric of her pajama bottoms, tracing smooth curves, and the outline of her groin seared itself into my gaze. It was a pair of pajamas I had seen countless times, but looking up from my knees made it look completely different.
That woman is my fiancée. That body.
The thought made the inside of my slacks grow agonizingly tight. All the exhaustion from the office evaporated; nothing existed anymore except the body right before my eyes. I gulped. My crotch swelled, tenting against the fabric. Unable to use my hands to cover it, I pressed my knees tightly together, praying silently that she wouldn't notice.
"What do you think you're doing?"
Her voice was frigid. The grip on my hair tightened with painful force.
"Ugh...!"
"Your Master is speaking, yet all I hear is the sound of your eyes rolling around."
"Woof, woof-woof! Woof...!"
I desperately wanted to apologize, but human words were forbidden. All I could do was bark with everything I had.
Soyoung leaned down even closer. The humid, musky warmth rising from between her breasts drifted into my nostrils. Alarm bells blared in my head. I knew that one more misstep would ruin me, yet my eyes kept wavering. I tried to focus solely on her face—I genuinely tried—while my heart hammered wildly against my ribs.
"You crazy bastard. Getting slapped by your girlfriend, kneeling on the floor, and getting cursed out turns you on?"
"Woof, woof...!"
The toe of her slipper wedged itself between my knees. My thighs twitched.
Tap.
"Ngh."
Tap, tap, tap.
"Ah, ngh, ugh!"
Every little prod stole the air from my lungs.
"Ngh... woof..."
When I let out an urgent, defensive bark, a quiet scoff slipped from above. Her slipper didn't withdraw. Keeping its position, it bore down heavily against me.
"Ah...!"
My hips bucked involuntarily.
"Stay still."
Her voice was flat and cold. Tensing every muscle, I gritted my teeth and braced my body. Even so—
"Ah, ah, ugh... W-Woof...!"
It was utterly futile. The moment her foot began to move, I realized just how helpless I truly was.
"Haa, ah, ngh..."
Bracing myself only seemed to concentrate my senses further. I was hypersensitive. Though her movements were slow, the heat inside my pants flared instantly. Soyoung's foot pressed down with heavy, crushing force over my erection, yet the motion remained eerily smooth. Her foot slid faintly up and down, grinding in slow circles around the sensitive crown before pressing down firmly.
"Ah... hah, ngh, eep...!"
She pinpointed the most sensitive spot with uncanny precision. My body shuddered helplessly. Though I bit down hard on my lip, a pathetic whimper spilled past my teeth.
"Pfft."

A smirk curved the corner of Soyoung's lips. Her muffled snicker sent a wave of scalding heat rushing to my face. I was mortified. I had been slapped, cursed at, forced to bark like an animal, dragged by my hair, and thoroughly humiliated. I was supposed to hate it. I was supposed to feel shame and misery.
It was agonizing. It wasn't just that I was disgustingly hard; weeping pathetically beneath a few teasing strokes of my girlfriend's foot was humiliating beyond measure. And yet... even so—
"Ah...?"
Suddenly, the pressure vanished. Her foot pulled away, and the hand gripping my hair let go.
"Haa, haah..."
My held breath burst out all at once. My shoulders trembled, and I could barely swallow the saliva pooling in my mouth.
"Hngh... haah, haah..."
Even with her foot gone, the sensation lingered on my skin. If anything, the sudden void left behind felt sharper, radiating a deep, throbbing ache through my groin. As I knelt there flustered by a sensation both familiar and impossible to get used to, her chilly voice cut through the air.
"Straighten your back."
I scrambled to fix my posture. It wasn't a deliberate decision—pure reflex took over. Not that it was anything to be proud of, but I managed it properly this time; my body responded that quickly. Even so, she clicked her tongue in irritation.
"Haa... On your stomach."
"Woof, woof!"
What did I do wrong? The moment she clicked her tongue, panic had spiked. My mind raced to figure out where I'd slipped up. Yet as soon as the command fell, I dropped flat onto my stomach and raised my rear into the air. It felt unnervingly natural, yet sickeningly unnatural. My body had moved before thought could even form.
I had only obeyed her orders, but my face burned scarlet. To be posing like this in front of my girlfriend was unbearably shameful. When I watched it in adult videos, it always looked like an alluring posture, but doing it myself felt utterly degenerate. Truthfully, she had only told me to get down, never to stick my ass in the air. I hadn't even realized that until now—I was simply engulfed in shame.
The shuffle of her slippers crept up behind my back. Thump, thump. The sound of slippers dropping off her feet.
Thump, thump. My heart pounded. The slippers alone had been intense enough—could it finally be...?
Haah, haah...!
The top of her bare foot slid down between the cleft of my buttocks. Smooth, cool flesh invaded between my thighs. Her touch was almost careless, as if she were doing it without a second thought. Yet the moment her skin brushed against my tip, my mind blanked.
"Ah, ngh...!"
The hands braced against the floor trembled violently. Bare skin was on an entirely different level from rubber slippers. Even knowing what was coming, I couldn't brace against it. It wasn't a matter of strength. That was simply the power of a woman's body—a structure I had been fundamentally born incapable of defying. Even to myself, it was a bizarre thought. It felt like fatalism, yet I resented it; I felt compelled to surrender to it.
Why? Why was I like this?
What happened to equality? Men and women were equals; patriarchal supremacy was outdated nonsense. Nor was there any need to flip it into female supremacy. Everyone was the same. I shouldn't be accepting this.
Then why was I doing this? This couldn't be happening. It made no sense. And yet, not even a speck of a desire to stop crossed my mind. That was what disgusted me most. A creature like me—
"Mm... Choco. Do you really love my feet that much?"
"Ah, a-aang! Ang...!"
Every time my girlfriend's toes teased against my tip and my entrance, I felt an embarrassing rush of pleasure. Writhing and crying out in shrill whimpers while being mocked to my face, I found myself utterly abhorrent.
