The Bitch Training Was a Success Too
"Ngh?! U-uuungh...!!"
Startled by the sudden thrust of my cock, Cha Suah's eyes flew wide open.
It was understandable that she'd panic. From her perspective, the largest thing she'd ever seen in her life had just pushed its way into her mouth without warning.
Overwhelmed by the sheer volume she was experiencing for the first time, tears welled up at the corners of her eyes in an instant—purely physiological ones.
What do I do if she pushes me away?
That worry flashed through my mind for a moment, but fortunately, my fear never came to pass.
Instead of instinctively pulling her head back or shoving me away, she began straining to open her mouth as wide as she could, desperate to take my member in fully.
"Chuup... hooob... chup, jjok...."
"Mm, good. Very good. Just like that, keep going."
"Chuboo... churip... jok, jooop...!"
Even if she was the theoretical type, it seemed the department's top student hadn't earned her rank for nothing.
With almost no experience, she wasn't good from the very start, but she was skillfully adjusting her tongue technique in real time, drawing on the vast theoretical knowledge etched into her brain.
The tongue that had been frozen stiff with confusion at first gradually began to move fluidly, tracing every ridge and contour of my shaft.
Wrapping my cock airtight with her hot palate and tongue like a vacuum, she sucked on it with an awkward yet steady, sticky rhythm.
Wow, shit. This is no joke at all.
I momentarily forgot I was supposed to respond as a professor, utterly lost in her service.
Every time the warm mucous membrane of her saliva-drenched mouth softly enveloped my glans, admiration spilled out of me.
And when her tongue teased my urethra—clumsily, yes, but with dogged persistence—I nearly let out a groan despite myself.
A virgin who volunteers to become a bitch, and even her inexperienced mouth-pussy delivers a heavenly sensation?
There was only one word for it: insane talent.
"Ngh... very good, Student Suah. You're keeping up quite well."
"Chuboo, ub... gah... chuooob...! Gahahaia...♥"
"How does it feel? Having your master's cock filling your mouth."
"Chuoob... guhod... heuu... guhoyeo...♥"
"Are you getting used to how a bitch is supposed to serve with her mouth now?"
At my question, Cha Suah lifted her dewy, glistening eyes to meet my gaze, my shaft still buried deep in her mouth.
Then, jaw stretched uncomfortably wide, she mumbled and struggled to squeeze out an answer.
"Uuub... u, yes... chup, M-Master... chuub...♥"
Her mouth was so stuffed full of flesh that her words came out completely garbled, and to top it off, she was drooling shamelessly—a hopeless mess.
Watching Cha Suah reduced to the very image of a vulgar bitch, I couldn't suppress a satisfied smile.
Just think about it.
The aloof, buttoned-up model student—wearing puppy ears, a tail plug buried in her ass, my cock in her mouth, babbling out answers of submission like a cooing infant.
Honestly, how the hell is anyone supposed to hold back against that?
My sadism and lust for dominion came boiling up, and I couldn't stay still a second longer.
Before her answer had even finished, I thrust my hips up hard and began pistoning roughly into her mouth.
*Thok!* Jjigeup...!
"Hooub?! Kkuk, kkeok...!"
At the sudden motion of my hips, Cha Suah's shoulders heaved violently as she gagged.
Well, of course—my glans was mercilessly jabbing at her sensitive uvula.
Even as her brow furrowed in pain, seemingly unable to breathe, she kept her laced fingers locked together and focused like a madwoman on serving my cock with nothing but her tongue and throat.
"Jjop... kkeok, chureurip! Chup... haaang, chup!"
"Ohhh..."
Every time I moved my hips, her head bobbed back and forth, the puppy ear headband fluttering wildly.
She tried tilting her head back slightly to catch her breath, but the cock hammering into her in steady rhythm seemed to leave her too dazed to manage it.
*Kkadeuk.*
"Heokeok?! Beuh, muhob...!"
"...It's all right. Keep going."
"Heuu, hauhi...!"
Cha Suah's upper teeth scraped lightly along my shaft, but I simply patted her head gently as if to say it was fine.
Honestly, it didn't hurt, and it was her first time—teeth grazing a little was only natural.
But Cha Suah, as if determined never to repeat the same mistake, strained with all her might to hide her teeth and keep her jaw open wide.
How could even her effortful struggling be this adorable?
I truly could not take it anymore.
"Student Suah. That was excellent service. Satisfying, even for a first time."
"Heuu... chuboub... gah, gahahahaia...."
"So then..."
Breathing roughly, I took the hand that had been gently stroking her and gripped her head with it.
Then I clasped her head with my other hand as well, pinning her completely so she couldn't pull away.
"This is the first praise sticker your master is giving you, so don't spill a single drop—take it deep inside."
"Ub?! Uuub...!!"
Without hesitation, I drove my cock all the way into the deepest part of her mouth.
And then I ruthlessly unloaded all the cum that had been building up.
*Byureureureuk! Byurit! Bsok!*
"Uuuk...! Kkeok, ub... kkullok!"
"Whew... not bad."
It wasn't the kind of blinding pleasure that wipes your mind white, but a pleasant climax still washed over me.
Cha Suah trembled all over as she took in the thick, murky semen that came pouring out like a burst dam.
Whether she was suffocating or not, her eyes rolled upward as if they might flip back entirely,
and yet she never once pushed my cock away, continuing to receive my cum right up until the very end of my release.
"Haa... haa... ugh."
"Good. Now then, shall we finish up?"
As the long, intense ejaculation gradually subsided, I savored the lingering heat and very slowly withdrew my limp member from her mouth.
*Pong.*
"Huab...!"
"Well done, Student Cha Suah."
"Haa... hauuu...."
Cha Suah, her head still held firmly in both my hands, crouched on the floor with her lips pressed tightly shut, panting for breath.
For a first experience, it had been quite painful and overwhelming—a hardcore practicum by any measure.
And yet in her tear-brimmed eyes, there was no resentment or fear toward me at all—instead, only a deep loyalty and a strange fondness seemed to glow within them.
That aside, it really was a magnificent sight.
Between her tightly closed red lips, the semen she hadn't managed to swallow trickled down in a sticky white thread.

That decadent scene—such a pretty face defiled by my cum—left me momentarily awestruck.
God, I could just shove it right into her pussy like this...
That beastly thought flickered through my mind, but I forced my reason back and cleared my throat.
I was a professor right now, after all.
A student had pushed past her limits to work hard for me; this was the moment to praise and acknowledge that effort.
"You did truly well. Calling it mere practice would be an understatement—that was exemplary service."
"Uub... gaheuhaia...♥"
"Ah, we haven't done the final step yet. Open your mouth as you are and show me the cum you're holding."
At my command, Cha Suah obediently opened her mouth wide, without a flicker of hesitation.

Resting on her red tongue was a full pool of my thick, fishy semen, enough to make it wobble with her breath.
The white liquid, thickened with mingled saliva, hovered precariously on the edge of sliding down her throat—that sight was, quite simply, sex itself.
Ha, seriously. This crazy bitch keeps bringing out the filthy words in me.
Once again I barely recovered my reason, and recalling the dignity a tenure-track professor ought to project, I opened my mouth.
"Very well done. A very pretty sight."
"Gah, gahaeo...."
"Good. You may spit it out, or if you wish, you may swallow it. The choice is yours, student."
At my generous offer, Cha Suah rolled her eyes thoughtfully for a moment, cum still resting on her tongue.
Frankly, this was her first time receiving a man's cum, and swallowing it right off the bat must have carried some instinctive resistance.
But her deliberation didn't even last ten seconds.
*Gulp.*
"Haua... I sw-swallowed it all... Master...♥"
Her slender throat bobbed up and down once, and my fishy semen vanished entirely into her stomach, without a single drop remaining.
Swallowing it should have been revolting, yet instead she looked proud, as if she'd proven her own worth, sticking her tongue out to lick up even the residue smeared around her lips.
Wow, she's the real deal. It's her first time taking it in her mouth ever, and that's the talent and execution she shows?
If her earlier confession about being a virgin was no lie, then that was a genuinely reality-defying talent—a depraved masochistic bitch prodigy.
Maybe the curse of the Altered Common Sense was, in fact, a blessing.
Swallowing my admiration, I picked up the tumbler sitting on one side of the desk, unscrewed the lid, and handed it to her.
"You've worked hard. It must have tasted musky, being your first time. Drink some water and calm down."
"Ah...! Th-thank you, Master...."
Cha Suah respectfully accepted the tumbler with both hands and gulped down the water greedily. Her water-dampened red lips glistened all the more vividly.
While she quenched her thirst, I pulled wet wipes from the desk drawer and roughly cleaned my slick cock and crotch.
Honestly, I was still holding back.
Watching that shameless display, her love juices dribbling down, the urge to drag her to the sofa right then and there for round two surged through me like mad.
But I pinched my thigh and barely clung to my sanity.
Today was our first meeting and her first experience; if I went all the way now, the fun of taming her later would be cut in half.
Only by slowly stoking the tension, gradually molding her into the shape I desired, would the eventual feast taste that much sweeter.
Besides, there was a far more pressing practical matter.
I still have two more students to interview.
Lee Songi, the airheaded bombshell freshman, and then Baek Nahee, the bitch I absolutely had to put in her place.
I could let Songi slide with a light touch, but with Baek Nahee I needed to leave my cum's scent stamped deep into her to break her spirit.
If I drained myself two or three loads more here, I'd seriously end up wrung dry like a mummy before the day was out.
Even with my twenties not yet bent, if I squandered stamina and virility this recklessly, I could collapse before ever properly enjoying my campus life as a tenure-track professor.
Shaking off my lingering regret, I zipped my trousers back up neatly.
Then, smiling at Cha Suah as she set down the tumbler and caught her breath, I spoke.
"Thank you for your hard work, Student Cha Suah. Now that I've confirmed your resolve, return to being my student and go back to your daily life."
"Ah, yes.... Master—no, Professor."
"We covered a lot of ground for a first session, so it must have been tough. Hurry and get dressed, head back to the dorm, and rest."
"Yes, Professor...!"
"And the tail... use your own judgment on that."
With my permission granted, Cha Suah struggled to her feet on unsteady legs.
She hurriedly gathered up her scattered underwear, skirt, and silk blouse from the floor and put them back on.
Fully dressed again, she had returned perfectly to the pristine, cold composure of an elite university student—the very image of the girl who had first walked through my office door.
Though, of course, that tail plug, still buried in her ass, remained hidden beneath her skirt.
"Then... I'll be going, Professor. I look forward to our next practicum."
"Yes, off you go."
Cha Suah bowed to me at a crisp ninety degrees, then made her way to the office door with quick, mincing steps.
It seemed the tail plug kept her from taking wide strides.
God, just watching that is almost enough to break my restraint.
*Thud.*
"Phewww..."
Once the door closed and her presence had completely faded, I slumped back into my professor's chair.
With the taut tension finally released, a long sigh of relief escaped my lips before I knew it.
"Haah, shit. I survived."
Cha Suah's mouth-pussy.
Honestly speaking, it was staggering—beyond anything I'd imagined.
That kind of snug grip and suction, on her very first time.
What would happen if someone with that much talent, that much affection for me, actually acquired real technique on top of it?
By then she'd probably become the ultimate onahole who satisfied me unprompted, all on her own.
"Seriously, am I even going to survive from here on out?"
I let out a hollow laugh as I smoothed down my crotch.
I'd only finished the first meeting with one of my personal students.
I couldn't even guess how much more stamina I'd need to expend from here.
And with that happy dilemma in mind, I waited for my second student to arrive for her meeting.
