Meanwhile, at that exact moment, Song Jiwon.
After finishing her class, she slipped into her private office and quietly locked the door behind her.
She immediately opened her laptop, pulled up Twitter, and checked the account that was already logged in automatically.
Her timeline was flooded with dozens of comments pouring in nonstop beneath the verification video and photos she had uploaded just moments earlier.
‘That comment I left this morning… Master must have already seen it…’
‘It felt so good that I couldn’t help myself… but still…’
Song Jiwon lightly bit her lip and placed her fingers on the mousepad.
She began scrolling slowly, reading each comment one by one, but before long her eyes were half-lidded as she stared at the screen.
‘I wasn’t supposed to comment without permission…’
‘Even so… I want to do it again… My hand keeps moving on its own…’
The thought that she had posted without permission made her increasingly anxious, yet the opposite impulse—to do it again—rose dizzyingly inside her.
“I have to ask him properly when I get off work today… whether I’m allowed to comment…”
“And… what kind of character I’m supposed to be on Twitter…”
The tone, behavior, and attitude permitted to her…
She wanted to know. Only then could she truly perform the role of his bitch in a way that would satisfy him.
The more she sank into those thoughts, the more her lower body gradually, strangely, began to heat up.
‘Ah… If Master had class today too… by now he would be…’
‘Haa… I… want it so badly…’
Still seated, she slowly crossed her legs.
The inner thighs pressed tightly together, sending a faint stimulation toward her pussy.
At that brief, sharp pleasure, her body trembled slightly and her breathing grew thin without her realizing it.
‘No… Not now… I still have classes left…’
She tried to reason with herself, yet her body was already recalling her master’s fingertips, replaying every movement from before.
The more the sensation between her crossed legs intensified, the harder it became to suppress the rising urge inside her.
Consumed by lust, Song Jiwon could not even remember how she finished her class.
Her body burned the entire hour as though boiling from within. She rushed through the lesson in a haze and left for Min-gyu’s house without properly packing her bag.
All the way there, only one thought filled her mind.
‘Ah… I can’t hold back anymore… It’s been so long since I tasted Master’s cock…’
When she reached the door of Min-gyu’s studio apartment, she stopped for a moment with her hand on the doorknob.
‘Haa… I’m sorry, Master…’
As if making a decision, she drew a deep breath and opened the door.
Inside, Min-gyu was sitting in front of his computer, enjoying a game he hadn’t played in a while.
With one side of his headset lifted, he spoke.
“You’re here?”
Instead of answering, Song Jiwon kicked off her high heels, spun around, and strode toward him without bothering to arrange them.
She roughly grabbed his face and immediately covered his mouth with her own.
“Huh… Mmph, what are you—”
Before Min-gyu could finish speaking in surprise, her tongue plunged in without giving him a chance to breathe.
Her breathing was rough and ragged. Deeper, more intensely, she chased after his tongue with her own.
Min-gyu’s chair tipped backward and his body fell to the floor.
In that instant, Song Jiwon placed her hands on his thighs and climbed on top of him in one swift motion.
“Wait, hold on— Ngh…!”
She seized his wrists as he tried to speak, yanking them down and pinning them to the floor with her full weight.
“Don’t move… You need this kind of reward too, don’t you, Master…?”
She immediately covered his mouth again, shoving her wet, rough tongue inside.
From his nape to his jawline, earlobes, and lips—she licked and sucked noisily, leaving nothing untouched, and let out a moan mixed with heavy breaths.
“Master… I missed you so much… I can’t just leave you alone anymore…”
Min-gyu’s wrists remained pinned beneath her. He could only roll his eyes, unable to move.
‘What’s gotten into her…?’
A flash of confusion crossed his mind, but a calculation quickly followed.
‘Hmm… I guess I can play along. After what happened today… and since I licked Aran’s pussy too… maybe she’s trying to punish me?’
The image of the slapper whip Kim Aran had given him surfaced in his mind.
‘Right. That thing Aran gave me… Now I have a reason to use it. I’ll match her pace… Yeah, sounds good.’
His expression remained hidden, but his eyes had already accepted the situation.
Beneath him, her body instinctively rubbed against his thigh, slowly riding the rhythm.
“Haa… haa… I’m sorry… Forgive me… but…”
“I’m not going to stop…”
Her words were barely sentences—just breath, desire, and thirst itself.
Song Jiwon pressed her entire body down, crushing his arms.
She exhaled roughly, closed her eyes, and whispered.
“Please… don’t resist… I’ll take my punishment… I’ll be scolded…”
The moment those words left her lips, she released his arms.
She grabbed her bra and tank top together and yanked them off in one motion.
Cool air clung to her heaving breasts.
She stood up, looked down at Min-gyu, and slowly began unbuttoning her jeans.
The zipper came down; the pants caught on her thighs. She pulled her panties down with them and kicked everything aside.
There was no hesitation, no shame in her movements.
Like a beast… completely natural.
Her gaze dropped between his legs.
She lunged at him like a starving hunter.
She roughly yanked down his sweatpants and underwear, bunching them around his thighs, then gently caressed his balls with one hand.
The heavy heat filled her palm.
Her mouth immediately swallowed his cock.
She licked the foreskin, then the exposed glans. Her tongue circled the tip, saliva dripping as she lapped at it like an animal.
With his cock still in her mouth, Song Jiwon slowly dragged her tongue along the underside of the glans.
The firm sensation against her tongue made her breath hot.
She opened her mouth wider, rolling the glans inside, and spoke.
“Just… put milk in my ass…”
She took the glans deeper into her mouth, swallowing it all the way to the back of her throat and sucking hard. Saliva streamed from the corners of her lips.
“Don’t fuck me… and post it on Twitter…”
She pulled his cock out for a moment, then licked between the foreskin and the base again.
Saliva glistened over the glans.
“Make me… your fap material…”
Now she wrapped one hand around his balls and slowly rubbed them. The heavy pair twitched beneath her palm.
“At the department store stairs…”
She took his cock back into her mouth and muttered.
Her wet tongue curled around the tip. Eyes closed, she sucked like a madwoman.
“I even sent you… pictures of my tits…”
She swallowed him to the root once more. Her throat tightened around him as she spoke in a voice thick with saliva.
“Because you wouldn’t fuck me like this…”
His cock slipped from her mouth, glistening wet.
She gripped his thighs with both hands, flicking her tongue over the glans again and again.
“I’m sorry… If I don’t do this…”
She pushed his cock deep into her mouth once more. Her tongue pressed and circled beneath the glans while saliva dripped down. She smiled.
“I think I’m going to lose my mind… Master…”
Normally she would have waited patiently while pleasuring him, but not now.
Her unfocused eyes chased only lust. There was no waiting, no hesitation.
Judging that he was sufficiently hard, she climbed onto his thighs.
Squatting, she grabbed his cock with one hand and rubbed the glans against her pussy.
The slick folds clung to it, parting wetly with each pass. Every time his glans brushed her entrance, her juices ran down his shaft.
Squelching, slippery, obscene sounds echoed between their flesh.
She held her breath, rubbing her pussy against his cock as if trying to split herself open, then gripped the glans tightly and shook it up and down to check how thoroughly she had soaked him.
Then she twisted her body, changing position into something even more lewd and beast-like.
She shifted her pussy aside and slowly guided his cock toward her ass.
With trembling hands she pressed the glans against her anus.
There was no lube.
Driven purely by the urge to be fucked, she hadn’t spared it a single thought.
Her asshole was already wet. Whether from her own juices or tension, she spread her cheeks with her hands and began pushing the glans inside, slowly, agonizingly slowly.
Her anus clenched as if trying to push him out. Still, Song Jiwon forced his cock in with her body weight.
“Hnnngh… Aaaah… Hnn…!”
She swallowed a moan that mixed pain and excitement. Biting her lip, she slowly lowered her hips.
Min-gyu’s glans forced her open. The hard shaft began to invade her ass.
The tightness was rough and hot. She flinched, gasping as the sensation overwhelmed her.
“Hah… Master… Aang… Hnn…”
She continued pressing down until she had taken him to the root. The foreign sensation of being stretched and the sharp pleasure shot up her spine.
When his cock was fully buried and twitched inside her, she ground her soaked pussy against his pubic bone.
“Hah… Deeper… Please go deeper…”
She rocked her hips back and forth, rubbing her pussy against his pelvis in a slippery motion.
Every time her wet folds dragged over the hard bone, a whimper escaped her.
“Nngh… It feels good… Like that… Make my pussy feel it too…”
With his cock buried to the hilt in her ass, she moved her hips and ass in a steady rhythm. She twisted, searching for the angle that would stimulate both holes the most.
“Hnn… Master… Min-gyu… I’m sorry… Forgive me… Just for today… I’ll rape you… Please forgive me…”
This was no longer submission or patience.
Like a bitch swept away by lust, she looked down at Min-gyu with a dazed smile.
“Hnn… Master… Min-gyu… I’m sorry… Forgive me… Just for today… I’ll rape you… Please forgive me…”
She slowly brought both hands to his neck. Her small hands wrapped around his throat.
At first it was almost gentle, but gradually her fingers tightened. She began to choke him.
Matching the pressure, her hips moved more roughly—up and down like a piston.
Every time her ass slammed down, his cock drove deep into her rectum, filling the room with wet, obscene sounds.
“Hnn… Fuck me… Harder… Haa… I’ll do the fucking…”
She thrust her hips while squeezing his neck tighter. She could feel his pulse beneath her palms, his breathing growing ragged.
Min-gyu’s face flushed red. Instinctive wariness flickered in his eyes—‘Isn’t this… a little dangerous…?’
But he didn’t resist.
He trusted that Song Jiwon would never truly hurt him. With that single belief, he surrendered himself to her.
While fucking her own ass and chasing pleasure in a frenzy, she saw Min-gyu’s face turning purple from lack of air.
She slowly eased the pressure on his neck.
Yet there was no confusion or guilt in her eyes—only unfocused pupils and the face of a bitch completely drowned in lust.
“Haa… haa… Min-gyu… Teacher… is raping her student… Haa… It feels so good… Teacher’s going crazy…”
Her hands moved to his chest. She pushed herself upright, rising onto her heels and spreading her legs wider.
The position was obscene.
Her ass was lifted high, his cock still buried deep inside it.
Staying in that pose, she began slamming her hips up and down like a madwoman.
Thud! Thud! Slap! Squish—
Her anus clenched as though trying to tear itself apart, yet the wet sounds of flesh meeting flesh echoed relentlessly.
“Hnn… Good… So good… I’m really… a bitch addicted to cock…”
Every time her thighs slammed against his pelvis, her asshole squeezed and sucked greedily at his cock.
She was no longer a “woman.”
She was a beast gone mad with pleasure, unable to tell whether she was his bitch or his teacher.
With nothing but his cock in her ass, every boundary melted away.
Her thoughts blurred, her breath burned, and all that remained was a body lost to ecstasy.
She became nothing more than a beast greedily taking Min-gyu’s cock deeper and harder.
