"Higuuh—?! A-again— nnh, nnn♡!!!"
Sion's hips lurched upward and she climaxed again, easily, helplessly. Straining her neck back as far as her limited movement allowed, she tried to let some of the pleasure escape — but the wide-legged squat that left her clitoris exposed, thrust forward and offered up, was not something she could change.
With each merciless forced orgasm, Sion's reactions grew a little more unrestrained.
"That makes ten. Carnal Arcana demands a more refined degree of magical control than most of you have been imagining. Even crude power-based casting is enough to bring Sion to climax in her current state — but if you refine your magical precision, you can produce significantly stronger pleasure. Next — Lidia. Keep that in mind as you try."
"Yes, I'll try."
"Ngh… uh, ah♡… auu— nnn~~~~~♡"
Sion had no way to resist the Carnal Arcana being used on her — the first she had ever experienced in her life. Even attempting to endure it, to grit through it, was nearly beyond her.
And yet — this was Carnal Arcana at only its most foundational level. Sion was being used as a plaything as part of the other students' basic practice drills.
"NNaah—?!♡ Ugh, ngh, nnnNnn♡nnN——!!"
A wand was aimed at her clitoris. A spreading warmth bloomed there — like a spotlight of heat — and translated directly into pleasure.
Class had barely begun.
Even so, the continuous forced orgasms at short intervals were steadily draining Sion's strength.
"Ah, no—?! Ngh!! St-stop it! Please— NNaah aaaaah♡!!!"
"——~~~~~~~~~~♡!!!" Eleventh climax.
At the slowest, within one minute. At the fastest, within about ten seconds — that was how quickly Sion was being made to come now.
The Arousal Excitation spell the instructor had cast had already sensitized her clitoris to the point where the lightest touch sent sensation spiking through her. And onto that hypersensitized flesh, Carnal Arcana was being applied again and again.
The more she came, the less she was able to hold back.
"Next. Inducing climax quickly is not the only goal — producing deeper, stronger pleasure is equally important. Adjusting your output in response to Sion's reactions will make your casting more effective."
"Ah— ngh! W-wait, just a — let me — rest, just a little — nnAah♡?! ♡"
Before the waves from one orgasm had even receded, a new student stepped up and pressed a wand without ceremony against Sion's clitoris, blasting Carnal Arcana directly into her.
She was ashamed — desperately, unbearably — and yet Sion couldn't suppress her voice anymore.
And every time a student switched out, the instructor interjected with measured advice, which only made things worse.
"Fh— fh— fuh— hah……ngh♡ kuu~~~♡?! ♡♡♡!!!"
That continued, mercilessly, eight more times.
◆
"Uhh… aah… ♡… ahh…"
The nineteenth student finished.
Even when no spell was being cast, Sion's hips kept twitching and convulsing involuntarily, and slick fluid ran in rivulets down her inner thighs and dripped to the floor.
Forced to climax so many times in such rapid succession, Sion's eyes had gone glassy and distant.
"Wow… that's rough. How many times has she come now?"
Sion lifted her gaze — and found herself looking up at the last student, a tall girl staring down at her.
Open contempt. Undisguised scorn.
A thin, mocking smile playing on her lips, the girl leveled her wand at Sion's swollen, reddened clitoris.
"You… try it yourself… and see how you like it…" Sion said back, her voice small and trembling.
Even used and tormented by a whole roomful of students, defiance still burned in her eyes.
"Hmm… You're making quite a spectacle of yourself, and you still have the nerve to talk back?"
Cru-nch.
"Ngh— ?! Kh, hah… hah… hah… ~~~~~~~~~~"
The tall girl pressed the tip of her wand beneath Sion's clitoris and lifted — a delicate, deliberate pressure against the engorged little bud.
A fear like having a blade pressed against her skin seized Sion, and she went utterly still.
Beneath that casual, careless manner, this girl was the top student in the class.
The others had been using Carnal Arcana on Sion as part of class practice — nothing more. But this girl had clearly found something she was actively enjoying: the pleasure of tormenting a helpless target.
"Looks like you haven't had nearly enough. Let me make you feel even better."
A low hum resonated from the wand tip pressed beneath Sion's clitoris — dense magical power pouring in.
"Ugh?! Kuooooh♡?! ♡"
Instant climax.
A beat later, she realized — pleasure and vibration were both being delivered to her clitoris at the same time.
A spurt of arousal fluid escaped her, and Sion writhed in agony.
"NNaahuu aauuuuuh♡?!?!! ♡♡♡"
Ten seconds. Twenty seconds.
A tier above all the Carnal Arcana that had come before. And it wouldn't stop.
She was pushed straight into a second, deeper climax.
"AhAAAaaa♡!!! ~~~~~~~~~~♡?!"
There was no keeping her voice down. If she could have moved, she would have flung herself away from the vibration hammering the underside of her clitoris that very instant.
But the spread-legged, hips-lowered stance couldn't be changed. She couldn't escape the wand that rested against her, barely even touching — just barely.
Thirty seconds.
She reached a third climax, and finally the vibration began to ease.
"Kah— …… Hah……… hah……… haah, hh—"
(It's… finally… over…)
"Why do you look relieved?"
The strong pulse of Carnal Arcana surged back, full force.
Into Sion, who hadn't yet come down from the chain of orgasms — another wave of pleasure, forced in on top.
"NaAH?! NNaaaaaaaah♡! Why— stop it— let me go——!!"
Stimulation to a clitoris caught off-guard was devastating. Sion struggled with more force than she'd managed all day.
"Wait— stop?! ~~~~~♡?! St-stop, I said— STOP♡!! STOP IT——!!!!"
Her hips jerked hard upward, then shook in continuous convulsion.
A powerful orgasm. Her speech was breaking down. The expression on her face — eyes wide, screaming — was a genuine plea for mercy.
"There you go. Plenty left. Varying the intensity makes it worse, doesn't it?"
"KuuaAAAaAaaaaaah♡♡♡!!!"
The tall girl eased the vibration down — then drove it back up all at once.
Against Carnal Arcana controlled with this precision, Sion was completely helpless.
"HiiiIi♡?! I— I'm coming!! I'm already coming, so stop— please——!!"
"So? It doesn't matter how many times you come. That's your problem. If you don't want to come, try holding it back for once."
Merciless pleasure crushed down on a clitoris in mid-climax.
Sion arched her immobile body back as far as it would go, clenched her teeth, and waited for the wave to pass.
"Also — did you just say 'stop'? What exactly does a piece of teaching material think it's ordering around?"
"AuUaaAAAAh♡?!"
The tall girl's voice was soaked in glee and sadism, and she varied her Carnal Arcana output with even finer precision.
"Besides, it's not 'stop,' is it? A lowborn commoner like you should be grateful we're even letting you participate in our lesson."
"Ah!! No— ngh kuu♡! Not that— STOP that— nnAH♡!"
Orgasm before the last one had ended. And through that orgasm, the vibration against her clitoris continued unbroken.
"Come on, try saying 'thank you.' Say it, or I'll keep you coming until you do."
"~~~~~♡!! I— I won't!! I'll never— say— something like that— ♡"
"Fine. Then come."
"KuuaaAAAAaaaaah♡♡♡!!!"
A sensation like her clitoris was being seared from the inside. An unbearable burning, as though hot metal were being pressed against her. And yet Sion couldn't change her position, couldn't escape the Carnal Arcana — she was forced to keep coming and coming.
"Come on, admit defeat already. No one's coming to save you. Even the instructor won't stop me. No matter how much you thrash and scream, this is a perfectly legitimate class exercise. So go on — let me make you feel even better."
"Ugh, kh♡ auuuuu! ♡! That— please— Instructor— help— HIGYA UUH♡?!♡♡"
Harder — and the wand tip ground into the base of her clitoris. Just as the tall girl had said, the instructor only watched Sion's anguish in calm, measured silence.
"You know, doing this, I can actually tell the exact moment you come. The magical feedback — I can sort of feel how much pleasure is being produced. That's five now — oh, six? Can't you resist at all? You keep coming so easily, it only gets worse for you. Ahaha."
"NGiuu uuuUUuu♡?! ♡♡"
Seven in a row.
With one final, overwhelming orgasm, the tall girl at last withdrew her wand from Sion's clitoris.
Sion's head fell back, and she gasped — ragged, desperate, sucking air.
"Good. Leviar is the most accomplished. Seven times in one minute. Forcing consecutive climaxes at this rate will render a target incapacitated for some time."
Only now did the instructor step in to stop the tall girl.
"Furthermore—"
The instructor's wand flared with light.
"NGYAAAh♡?!?!!"
Sion squirted hard and climaxed — a release that eclipsed everything that had come before. And not just once. Pleasure too dense to individually register. In a single instant, ten orgasms' worth of sensation had been hammered into Sion's clitoris.
"As demonstrated — once you can deliver Carnal Arcana from a distance in a single instant, you are operating at a combat-ready level. Against a target with no tolerance for pleasure, incapacitation is guaranteed… That said."
The instructor pressed her wand to Sion's lower abdomen — to Sion, who was wide-eyed and reeling from the rapid cascade of deep orgasms.
"It is rare to find a subject with pleasure tolerance this low. Do not let yourselves become complacent about the convenience of Carnal Arcana — strive for ever finer magical control."
And with that — while commenting on Sion's weakness — she began engraving a pattern into her skin.
"Despite 36 additional climaxes — 46 total — Sion's body remains in a state of strong arousal. Once the Arousal Excitation spell is applied, the subject cannot come down from that highly orgasmic state until the spell is lifted."
"Ugh♡… ngh… uaaah♡!!"
The instructor traced her wand tip across Sion's skin as she lectured. Every time the wand grazed her still-erect clitoris, Sion's back arched involuntarily. The instructor's hands moved with the detached manner of someone handling a piece of equipment — no consideration for the student's pain, no restraint whatsoever.
Even without active Carnal Arcana, Sion came.
"From this point, we will change the conditions. Let us run through the exercise from the beginning once more."
The instructor's wand glowed — and the arcane marking she had engraved on Sion's lower abdomen activated.
