The 9th Period: Living Teaching Material
‘I was going to take Sera straight home… give her a bubble bath and play dress-up with her hair…’
Percival protested at the mention of supplementary lessons.
“What? This academy doesn’t even have night self-study, does it?”
Instructor Grenol smiled and replied,
“Instructors are allowed to arrange supplementary classes to help students improve their grades.”
“Since when?! Ah, right—Sera’s a new student today, isn’t she? So she should be exempt from supplementary lessons…”
“Absolutely not!! Sera is our academy’s finest teaching material. No… our special-treatment student. Ufufufu. Isn’t that right, Sera dear♡?”
＊ ＊ ＊
Eh?! Special treatment, my ass?!
I puffed out my cheeks in a sulky pout and shot back,
“Since when?! I’m just a normal student, mmph—mmph……”
Suddenly a group of male students rushed forward and clamped a hand over my mouth.
“Sir, please just start 9th period already!”
“Shall I?”
Percival’s expression twisted, but unlike in front of the other students, Grenol was still a legitimate academy instructor. There was nothing Percival could do.
“This… this can’t be happening!! This can’t be!!”
After shoving the wailing Percival out of the classroom and drawing the curtains to block the hallway view, Instructor Grenol turned back to the room.
With Percival’s apologetic gaze lingering until the very end, I found myself the center of attention in the middle of the classroom—everyone’s living teaching material.
“Now then, students. Shall we begin 9th period supplementary class—‘Sex Education’—so you can freely satisfy your academic desires?”
“Yes, sir!!”
*
The moment 9th period began, the male students and the instructor dropped all pretense.
They sat me down in the center of the classroom and began pulling out their cocks, pants already discarded. Dark-red, grotesque members sprang into view right before my eyes.
“Hik—hiiik…?!! You said this was sex education, so why are you taking your pants off?!”
The sex education I’d learned at school never involved this.
“Kukukuk. Practical, hands-on lessons are obviously more effective, don’t you think? Why? Do you need private tutoring from me? Just say the word if you do.”
“Don’t be ridiculous, sir.”
“I’m telling the principal.”
“Haha, just kidding. It was a joke.”
From the way they kept talking, I caught a hint that might help me escape this situation.
Ah, right. The academy’s principal, Layla, was a high-ranking mage who could use 5th-circle magic.
If I told the principal…
“Mmph, mmph…”
But one student kept his hand firmly over my mouth, so all I could do was drool and whimper incoherently.
Another student leaned in, lowering his head, and started stripping me.
“Huh? Didn’t we leave some pretty graffiti on Sera’s body this morning?”
“Wait, that was real?”
There were about ten male students in the classroom. Seven of them apparently lived in the dorms. The remaining three seemed unaware of the obscene graffiti incident from this morning.
Those three were even more enthusiastic.
“Hey, what kind of graffiti did you draw?”
“Show us too.”
“Ah, well…”
The boys began roughly stripping me.
“Hi—hiiik…..”
“Ehehe, bring that magic pen that doesn’t wash off easily.”
“Yeah, regular ink just gets wiped away by this bitch.”
The students stared at my now-naked body and smirked while holding up the magic pen.
“Move, I’m first!”
Magic pens weren’t something ordinary students could easily obtain. The first one to pull out a pen belonged to Dragan, whose family crest—a basilisk—marked him as a member of the Selton viscount house.
The Selton viscount house ruled the very territory I currently lived in. In the original novel, the heir to the Selton family was Hamilton. That meant Dragan was likely a branch-family member.
‘Soon his older brother Hamilton will come to my house to propose…’
Yet here was that very brother’s younger sibling, mercilessly scrawling vulgar graffiti across the body of the woman Hamilton would one day court.
Scratch, scribble—scratch—
He started with crude words across my chest, then didn’t stop there.
“Spread your legs.”
He drew an arrow pointing at my pussy and wrote more obscene phrases beneath it.
[No-Condom Sex Scheduled]
[Urine Enema]
Once he finished his filthy graffiti, the other students joined in, covering every inch of my body with vulgar writing.
Hik, no…! I can’t let them write more obscene things on me again!!
Startled, I tried to activate the Refresh skill.
This skill is on a 48-hour cooldown.
Damn it! What kind of skill has a 48-hour cooldown?!
Ah, right—what if I use the I Am a Virgin skill? Maybe they’ll all listen to me then?
I Am a Virgin
No recent sexual partners detected.
Damn it…?!
It only activates right after having sex, apparently.
Scribble, scribble.
In the meantime, Dragan had covered my body with even more lewd writing.
On my left thigh:
[Meat Toilet]
On my right thigh:
[Free Pussy Distribution]
Another student grabbed my hips, flipped me over, and started writing on my ass.
“I’m writing [Public Cumrag].”
“I’m writing [Slave Bitch].”
“Ehehe, nice! Let’s have a contest to see who can write the most degrading graffiti!”
The students’ eyes lit up with lust as they stared at my body, drooling.
Soon the words multiplied across my skin:
[Please Fuck Me] [Cum Receptacle] [Anal Slave] [Sex Almost Every Day] [No Boyfriend] [Bitch in Heat] [Titboy] [Trash Can] [365-Day Constant Arousal] [Cock-Addicted Slut] [Human Onahole] [Number of Times Fucked] [Training Complete] [Unfit to Be a Woman] [SEX Addict] [Everyone’s Bitch] …and more.
“Ufufu. Sera, you’re not allowed to erase the graffiti anymore.”
“That’s right. You’ll live as our slave until the day you die.”
“Don’t even think about getting married. This magic pen leaves tattoos that won’t come off no matter how much you wash.”
“Hngh…”
The real problem was that my body had become so sensitive that even the slightest male touch made me instantly wet. With several boys rubbing the sensitive tips of their pens across my skin, my pussy couldn’t help but heat up.
Right in front of everyone, shameful fluids began to leak from between my legs like I was peeing.
The boys watched in awe as my glistening, twitching pussy dripped.
“Whoa, looks like we’ve already trained Sera’s pussy pretty well.”
“Do you like it, Sera?? ♥♥”
“As expected, you get off on being treated roughly. Fine—today I’ll fuck you hard.”
One student suddenly lifted me by the arms and offered me to Dragan.
“Here, let the young master of House Selton go first.”
At that moment, Instructor Grenol stepped forward and shoved Dragan aside.
“Not so fast, you brats. Even cold water has an order. I’m first.”
Dragan smirked at the vulgar writing he’d scrawled across my thighs and said,
“Well, she’s a public toilet anyway. Does it matter who uses her first?”
Instructor Grenol grinned triumphantly.
“Ufufu! Then the written lesson is over. Time for the practical demonstration. I’ll show you how it’s done first—watch carefully and follow along.”
“Enjoy, sir,” the students replied.
Instructor Grenol began demonstrating the doggy-style position.
＊ ＊ ＊
Gluck! Gluck-gluck—
Even before he started, water was already trickling from between my legs. The moment Instructor Grenol pushed inside me, an indescribable wave of pleasure crashed over me and I let out a sweet scream.
“Aaaahng, haa ♥♡♥♡”
His thick glans plunged deep, scraping against my inner walls as he thrust forward.
Thud, thud, thud!!
The pleasure was easily twice as intense as before. Without realizing it, I wrapped my thighs around his waist and pulled him closer.
“Haa, haa. Sera, does it feel good?!”
“I don’t know, hic… Sir, you’re so mean~♡”
Thwack, thwack, thud!!!
Grenol pounded his cock roughly into my sopping pussy. Once my body had been properly developed, the way my walls clung to him felt even more obscene.
Grabbing both my arms, he rocked his hips while groaning,
“Whoa, Sera’s pussy… it’s gripping me even tighter than when I first took her virginity!”
“Really, sir?”
“As expected from the finest pussy in Selton Village, huh?”
Dragan, the young master of House Selton, shouted proudly,
“Wahaha! This is what Selton is all about. Got it, you idiots?”
Students swarmed in from all sides, sucking and leaving kiss marks across every inch of my body.
‘Aah, at this rate…’
My consciousness grew hazy. Only primal pleasure remained—nothing but instinctive ecstasy. I was turning into a vulgar, pleasure-drunk slut.
‘No… while I still have even a shred of sanity left… I have to use my trump card.’
“Hngh♥♡ I don’t want to feel even better than this…! So please, just let me go home. I want to go hooome…!”
“What are you talking about?”
“We’re going to fuck you all night tonight too. Kekek.”
At those words, I let out a sorrowful laugh and played my final card.
The one I had chosen was—
Sera has become everyone’s plaything…!
