The Milking Cow's Submission
Yuna stared at him in a daze, her face flushed crimson at Seong-il's words. Seeing her like that, he felt the sweet taste of victory in their little battle and raised his hand again.
Smack!!
"Kyaaah...!"
"Wrong. It's not 'kyaaah.' You say, 'Thank you~.' Why? Because from now on, you're my cumslut. Got it?"
"..."
At his words, Yuna quietly buried her face in the pillow, avoiding the answer. Watching her, Seong-il silently lifted his palm and began raining merciless slaps across her ass without pause.
Smack!! Smack!! Smack!!
"Ahng..! Ahht.. Hng..!"
Even as his palm brutally beat her ass, Yuna didn't resist. She only moaned. Seeing her like that, Seong-il continued the relentless corporal punishment, demanding an answer.
"Why aren't you answering?"
"Kk.. Khup..."
Smack! Slap!! Smack!
Yuna had been gritting her teeth, refusing to speak. But under his merciless palm, she finally reached her limit. Her ass trembling violently, she cried out.
"Stop...! Please stop...! I can't take any more..!"
Smack!! Smack..!!
"Then answer me properly?"
Seong-il kept spanking her ass without mercy as he spoke. Finally, Yuna opened her mouth and surrendered.
"I understand..! I get it...! I'll do it..! I'll do it, so please stop hitting my ass...!"
At her submissive declaration, Seong-il felt blood rush to his cock until it felt like it would burst. The excitement made him want to thrust straight into her pussy right then, but he held back with iron will and pressed her for the humiliating words.
"What exactly will you do?"
"Th-that thing..!!"
"What thing? Be more direct."
"That's too much..!!"
Smack!! Smack!!
The moment Yuna showed even a hint of defiance, Seong-il's hand flew up and struck her ass again.
"Kyaaak...!"
"Don't talk back like a brat. Give me the answer I want. Understand?"
"..."
Once again, Yuna fell silent at his words. Seeing this, Seong-il silently raised one hand high into the air.
"S-stop! I'll.. I'll say it..!"
"Speak."
"I'll become it... I'll be your.. c-cumslut!!"
After steadily training her for quite a long time, he had finally heard her vow of submission. The moment those words left her lips, a refreshing wave of pleasure washed through Seong-il's mind. Drunk on that feeling, he grabbed her plump ass with both hands and began pushing his cock into her folds.
"Ahng...!! W-wait, what are you..!"
"What do you mean, what? You literally said it with your own mouth just now. You're my cumslut. What's the problem with me using my own cumslut?"
Having said that, Seong-il activated his sexual technique to the extreme and began brutally thrusting his cock into Yuna's pussy.
"Ahng... Ahng.. Aang...!"
Her ass was more voluptuous and softer than any woman he'd ever slept with. Gripping those plush cheeks with delight, Seong-il kept slamming his hips without pause. Under his relentless pounding, Yuna's massive breasts bounced wildly as her entire body accepted his brutal rhythm.
"Ahht... Ahht...!!"
Leaning over her like a beast in heat, Seong-il pressed his upper body against her back and whispered into her ear.
"How does Master's cock taste?"
"...!"
Overwhelmed by both pleasure and shame, Yuna buried her face in the bed, refusing to answer. Seong-il's expression twisted with annoyance and he stopped moving his hips.
"Wh-why...?"
Yuna had been lost in the overwhelming pleasure flooding her pussy. When he suddenly stopped, she looked up at him with a bewildered expression.
Slap!
Seong-il lightly backhanded her face as she stared at him.
"Ahht...!"
"You dare close your mouth when your Master asks you a question? You still don't know your place?"
"S-sorry..."
"If you're going to be sorry, don't do it in the first place, right?"
With that, he raised his hand again and brought it down hard on her ass.
Smack!! Smack!!
"Ah.. Aah..!"
After receiving well over fifty spanks, Yuna's ass had turned bright red. Unlike the beginning, the pain now felt sharp, and she let out pained moans.
Smack! Smack!!
"Ahng...! Ahhng....! It.. it hurts..!!"
Yet Seong-il showed no mercy, continuing to slap her ass repeatedly. Trembling, Yuna begged for mercy.
"Please stop..! I was wrong...!"
"Master."
"Yes...?"
"If you're a cumslut, you should call me Master like one. Where did you sell your honorifics?"
After saying that, Seong-il raised his hand high once more. Startled, Yuna quickly spoke.
"S-sorry! I was wrong, Master...!"
Interestingly, the moment those humiliating words left her own mouth, Yuna felt her pussy grow hot again and a strange pleasure echo through her mind. While she was confused, confronting the true nature hidden inside herself, Seong-il gave a wicked smile at her satisfying answer. He grabbed her glowing red ass once more and began thrusting into her.
"Ahng...!"
The heavy, thick intrusion filling her pussy again. Overwhelmed by that scorching pleasure, she stopped thinking entirely. She buried her face in the bed and focused solely on feeling his burning cock.
"Ahng.. It feels good.. So good...!"
Seeing her like that, Seong-il finally lost all restraint and began slamming his hips like a wild animal. After ravaging her like a beast for a long time, he felt a powerful climax building deep inside and began pumping thick ropes of cum into her.
"Aah..?!"
The moment Seong-il came, their senses linked, and Yuna experienced an intense orgasm unlike anything she'd ever felt before. It wasn't the awkward, painful pleasure she'd known from clumsy sex with other men. This was pleasure amplified several times over by his sexual technique. The overwhelming ecstasy flooded her brain until she couldn't endure it. She squirted violently and passed out.
"Khh... The grip is pretty damn good... Huh?"
Seong-il noticed that Yuna had fainted right as he finished his first load. He stared at her in disbelief.
'Huh...? Was the stimulation too strong because it was her first time...?'
His lust wasn't fully satisfied yet, but he couldn't wake a woman who'd passed out. With a sigh, Seong-il lay down beside her and began kneading her enormous breasts while thinking.
'Well... It's not like today is the only day.'
Having finished that thought, he gently pulled her into his arms, stroking and playing with her soft skin until he drifted off to sleep.
The next morning.
"Ugh... Mmm...?"
Early morning. Yuna woke to a dull ache in her ass. She felt something heavy and warm pressing against her chest and looked down with a dazed expression.
"Uh... a hand...?"
Startled, she sat up quickly. In front of her was a muscular man.
"Wha... what..?!"
Seeing Seong-il sleeping peacefully beside her, she panicked. She pulled the blanket over herself and recalled the previous night. The humiliating sex. The vow of submission. As memories of last night flooded back, her face burned with shame.
Yet strangely, along with that rising shame, she felt her pussy growing hot again.
'Again....'
Without thinking, she reached down and touched herself. Her fingers came away soaked with her own juices.
"Gulp..."
Sudden heat surged through her, making her face flush even hotter. While she was still confused and flustered by her body's reaction...
"What? You're awake?"
"!!!"
The moment the man who'd toyed with her so shamefully the night before opened his eyes, Yuna panicked. She quickly wrapped the blanket around herself and took a defensive posture.
Finding her reaction cute, Seong-il chuckled lightly. Then he moved roughly, pinning her beneath him on the bed.
"What's this, my little cumslut? When your Master wakes up, you should greet him properly. Your attitude is terrible, isn't it?"
"Ah... Ahht..."
Seong-il pinned her down, roughly yanked the blanket away, and began sucking hard on her neck.
"Ahng...!"
After savoring her neck for a while, he paused his ministrations, pressed his lips to her ear, and whispered.
"Did you already forget the title you were supposed to use when we're alone together?"
"Th-that was..."
"Hmm... Looks like your training is still lacking. Should we start morning exercise then~"
"....?"
Yuna's eyes widened at the sudden mention of exercise. Ignoring her, Seong-il got up, roughly flipped her over, and positioned her in doggy style.
"N-no way?!"
Yuna finally understood what he meant by 'exercise.' She struggled desperately, trying to escape his grasp, but Seong-il's body—empowered by inner energy—didn't budge an inch.
Smack!!
"Kyaaak...!"
"Come on. Let's have another self-introduction session with our Yuna, shall we?"
As he spoke, he roughly kneaded her ass like he was pinching dough, rubbing his hardened cock against her entrance.
"Huuung..."
His hot shaft rubbing against her already soaking wet pussy made her moan involuntarily, her face twisting with arousal.
'Saying she doesn't want it with her mouth, but her body is completely honest with its instincts.'
Thinking that, Seong-il pressed his stomach against her back again, kneading her breasts as he whispered into her ear.
"Now. Yuna. Repeat the self-introduction you did yesterday. If you do, I'll play with you as happily as last night."
"....."
Yuna remained silent for a long time. To break that silence, Seong-il moved the hand kneading her breast to her nipple. He poured inner energy into it and pinched hard, pulling it outward.
"Aang...!"
The electric pain shooting from her nipple made her body shake as she let out a lewd cry. Seong-il kept tormenting her nipples, demanding an answer.
"Are you going to keep this up? I can play with your tits all day, you know...?"
"Ahht... Ahng... Hng...!!"
He kept kneading and demanding, but Yuna only moaned lewdly without answering. Growing irritated by her half-hearted attitude, Seong-il issued an ultimatum.
"This is your last chance. If you don't want to, just say so. I'll stop and leave. Understand?"
"!!"
"I'm counting to five. Answer before I finish. Five... Four.... Three...."
At his words, her complexion changed drastically as she agonized. After opening and closing her mouth several times in that short moment, she finally closed her eyes and spoke.
"Y-Yuna is Master's cumslut. And... and Master's milking cow as well. M-Master... P-please roughly fuck my pussy from behind...!!"
She squeezed her eyes shut as she forced out the humiliating words. Hearing her answer, Seong-il smiled with satisfaction.
'Perfect...!'
He had succeeded in making her say exactly what he wanted while she was still fully conscious. Overjoyed, Seong-il could no longer contain his excitement. Like the night before, he began thrusting into her like a savage beast.
"Aah..! It feels good...!! This is it...! Master's cock is filling my pussy completely...!!"
Yuna screamed in pleasure as his cock stretched her completely, heating her entire body. After declaring her submission to Seong-il, she felt the last fortress in her heart crumble. Lewd words began spilling from her lips without restraint. Seeing her like this, Seong-il felt his desire to dominate surge, and he focused entirely on enjoying her body.
They went at it like animals from dawn onward. Lost in each other, they didn't notice the sun rising brightly outside.
'Shit... I need to get to the office soon...?'
Seong-il, who'd been completely absorbed in the pleasure of being with Yuna, left her sleeping soundly in his arms and casually headed to the shower in her living room. After washing up, he returned to the bedroom and gently woke her.
"Yuna..! Yuna..! Sorry, but could you wake up for a moment?"
"Huh...? Yes? Y-yes.. Master."
"That's enough. You only need to call me that when we're having sex. Once the 'play' is over, you can call me by my name."
"R-really?"
The woman who'd resisted him all night only to be thoroughly broken blushed as she asked.
