The Masochistic Pig’s Training
I had secured a university professor as my sex slave with nothing more than a single beating.
I’d originally set my sights on Aunt Saehee as my first woman, my first female conquest, but somehow that had turned into Professor Han Yumin instead.
With nothing to my name, I had no choice but to bow before power. And honestly, making the professor my woman might have been a better choice than I’d expected.
For the price of a slap or two to the ass, I’d acquired a sex slave with a professor’s title. What better bargain could there be?
“First, cancel that class representative thing immediately.”
“Yes!! I’ll cancel it right away, Master♥”
For now, I needed to deal with the fundamental reason I’d been forced to come all the way to her lab in the first place.
I let out a relieved breath at the thought that I wouldn’t have to take on that annoying class representative position after all.
But the result was almost absurdly hollow.
Could it really have been this easy? How many choices had I made just to solve something so simple?
Well, still, I hadn’t taken a complete loss.
“Second, Professor, you’re nothing more than a toy. You’re not allowed to expect anything from me.”
“Yes, yes..!!♥ I understand, Master♥”
“Hm. Good. Then, as my toilet, how far can you go?”
“Anything I can possibly do, I can do it all♥ If I could only be raised by Master for the rest of my life..♥”
As if my thoughts had been meaningless from the start, the professor’s answer was excellent.
A declaration that, so long as I didn’t throw her away, she’d crawl under me for the rest of her life.
But then—
“You said it feels good no matter where I hit you, or what I do to you.”
“Yes!! Please do whatever you want, as long as Master desires it♥ Hit me♥”
Smack!
Before she’d even finished speaking, I raised my hand and struck the professor hard across the face.
It was hard enough to wrench her head aside, but instead of recoiling, she let out a cry of ecstatic bliss.
“Ughha..♥ Th-thank you!! Thank you so much for hitting me!♥”
The professor hit the floor in dogeza the instant she was struck, bowing low and thanking me.

“A toilet only takes what its owner gives it and keeps its head full of its owner.”
“Y-yes..!! I’m sorry..!!”
“Remember that. If you forget, then there won’t be anything you want from now on.”
“Hngh..♥ I-I’ll remember..!! I’ll never be so arrogant again, Master..!!♥”
She was older than I was, and far more educated as well.
But there was a mountain of things that still needed correcting, starting with that habit of daring to voice her wants to her master first.
Then I lifted her chin.
“You called yourself a masochistic sex toilet. So why do you keep speaking like a person?”
“Hngh..♥ I’m sorry I’m still lacking..!”
“From now on, whenever I hit you or when you’re so aroused you want to be beaten, don’t talk like a person. Bark on your own.”
“Yes, Master..!! I’ll remember!! Oink.. oink!!♥”
Even if she was a sex toilet, a toilet that squealed like a pig needed to be treated accordingly.
If I turned every conversation into animal noises, communication would become a nuisance, so I decided she’d only be allowed to bark when she was being punished or when I let her relieve herself.
“And Professor, you’re still unmarried, right?”
“No..! I’m married..♥ Does that bother you because I’m a married woman..?”
It didn’t bother me in the slightest.
If I had been bothered by that, I never would’ve expressed my feelings to Aunt Saehee in the first place.
On top of the fact that she was a professor, I was more interested in the satisfaction of being able to play with a married woman who still had a man at home.
And the more I listened to her story, the clearer it became that, despite the title of husband, they hadn’t even been intimate for years. In fact, her husband was the one having an affair, all while leaving such a lewd, filthy wife behind—something like that.
Ah. So she was this filthy because of that, huh.
In any case, that sexual deprivation and loneliness seemed to be what had twisted her into such a warped masochist.
“Should I.. divorce him..? If Master wants it, I’ll divorce him immediately..!!”
When I stayed quiet after that, she must have grown anxious, because she started talking about divorce first while watching my face.
“No. Don’t get divorced until I bring it up again.”
“Yes, Master!♥”
After she answered, I sat down on the sofa and pulled down my zipper.
I took the seat of honor—the very spot that had originally belonged to Professor Han Yumin—and at the sight of me settling in like that, she wore a delighted expression.
“Then come here and suck my cock.”
“Yes!!♥”
The professor crawled between my legs without the slightest hesitation.
She came so fast it was as if she’d happily crawl under my thighs if I told her to.
“Haaah..♥ Ugh..! I-it’s so big.. so huge..♥ I’ve never seen anything like this..”
It really was bigger than the size I’d known myself to have.
In Hajun’s memories, his cock hadn’t been particularly large—just average, really—but this one was enormous, so much so that I could feel how big it was even back when I’d been with Aunt Saehee.
It wasn’t as though my body parts could suddenly change on their own, so I figured the gift from that bastard in my dream had probably been this.
“Shut your mouth and keep going.”
“Y-yes..!!”
The professor’s hand wrapped around my cock.
Saehee might have been shocked too, but mine was truly far beyond the range of ordinary size.
It was bigger than the cocks in porn, and as that thing twitched in front of her eyes, the professor swallowed hard and wore the look of someone completely aroused.
“Suck it.”
“Hrrk!! Haaahup!!♥”
The moment I gave the order, she took the enormous glans into her mouth.
But because it was too large, her eyes rolled upward as my cock filled her mouth to the brim.
“Hmph. So you’re a university professor and a toilet, but your mouth-pussy skills are pathetic.”
“Ugh..! N-no..!! I’m still not used to it.. I’ll do better! I’ll try harder..!♥”
“Be quiet and keep going. Use your tongue more.”
She shook her head desperately as she sucked my cock with all her might.
But because it was so huge, it seemed to reach all the way to the back of her throat, making her gag over and over in misery.
Yet even that misery seemed to become pleasure for the professor.
“Until you get good enough to satisfy me with your mouth-pussy, no more spanking. Practice.”
“Hngh..!♥ Ma-Master.. p-please, anything but that..!!”
“Also, no touching yourself alone. Not a single finger on yourself without my permission.”
“No, Master..!! I might die..!! I’ll do better, Yumin will do better..”
No masturbation. No spanking.
To a woman whose brain was ruled by lust and masochism, it was no different from a death sentence.
The sight of her crying with the expression of someone who had lost the whole world was pitiful in all the right ways.
“If you want to get beaten again, then improve your skills first.”
“Ahh..”
“And I kept it standing too long, so it hurts a little.”
“I-I’ll help you right away, Master..!♥”
I’d reached my limit too.
The image of her naked body when I’d first seen her in the lab had burned itself into my mind, and my cock had swelled to the point of bursting.
So instead of waiting for the professor to move on her own, I grabbed a fistful of her hair.
“Hrrk..!! Uuup!!♥”
“If you don’t want to get hurt, stay still. Take it all the way to the back of your throat.”
“Hrrk..!!♥ Kheh..!! Kkugh!♥”
I forced my cock deep into her throat.
Tears spilled down the professor’s cheeks from the suffocating pain, but there was an expression in her eyes that words couldn’t describe.
“Ghuk!! Uup! Up!!♥ Kheup chuuup..!♥”
“I’m going to cum, so swallow every last drop. Don’t leave a single drop of semen behind.”
“Khhup..!!♥”
I drove into the depths of her throat according to my will, and before long, the urge to climax surged up hard and fast.
It felt like I was going to shoot at any second, so I immediately blasted my hot seed deep inside her throat.
She really was a fine toilet, because she swallowed every drop without spilling a single one.
“Thank you, Master..!! Gghhhup♥”
“That’s enough. You took it better than I expected.”
“Yes♥ If it’s something Master gives me, I could even drink piss..!♥”
“Come closer.”
After finishing, I called her back in front of me and made her kneel again.
The professor looked up at me like a dog wagging its tail, waiting for her next command.
Smack!
Without warning, I slapped her face as hard as I could again.
The impact made her body lurch sideways, and before even a second had passed, she was spraying pussy juice between her legs like a fountain.
“O-oh..!♥ Hngh..!♥”
“What did I tell you to say when you get hit?”
“T-thank youhhaa..♥ Gulp..!! Oink oink oink!!♥ Th-thank you for hitting me, Master!!♥”
She crawled on the floor, bawling like an animal exactly as I’d ordered.
A university professor, reduced to barking and begging at my feet like a beast.
That was enough training for today in the lab.
“Then let’s end it here for today.”
“Ughh..!!♥ C-couldn’t you do a little more.., Master.. n-no.. heheh..♥”
I kicked her aside coldly and left the lab.
The sound of my foot shoving her back, along with the professor’s pig-like noises drifting after me, rang pleasantly in my ears.
Even when she slipped from honorifics into plain speech midway through, I didn’t care at all.
“From now on, masturbation is banned for the rest of your life.”
“Ahh.. Th-that’s impossible.. Please..”
“But if you really feel like you’re going to die, ask me for permission. I’ll only let you do it in front of me.”
Professor Yumin wore the expression of someone who had lost the whole world at the words that she’d be forbidden from masturbating for life.
But then, with the next words that came to her like a rain after drought, her face softened again, and she was so happy that she even kissed the top of my foot.
A single masochistic sex-toilet pig that had chosen submission for itself.
As I patted her head and started planning my next move, class was already ending before I knew it.
It hadn’t been my intention, but with a professor on campus—especially the professor who represented the department—turned into my sex toilet, my school life was all but assured smooth sailing from here on out.
Now I could go home... except I had a dinner appointment with Yujin waiting for me instead.
I was a little drained after emptying myself out on the professor, but when I thought of Saehee, fresh energy somehow began to surge through me again.
The pig who simply vented her instincts and the woman I wanted, the woman I desired, were two very different things, and with light steps I headed toward the place where Yujin was waiting.
