“See? I’m not touching you with my hands.”

“That’s not the problem right now. What the hell are you trying to do?”

“You’ll see soon enough.”

The other half of the slime burrowed between my clothes. Something damp and sticky squirmed inside my shirt.

“Wh-what are you doing…!”

After slipping under my underwear, it clung firmly to both br*asts. As it moved sluggishly, my n*pples felt strangely ticklish.

“Kyaah! You perverted slime!”

“Devileth, begin.”

At that moment, the slime attached to my chest started vibrating with a humming sound. As my entire chest resonated, even my n*pples felt the subtle tremors. My body twitched and rough breaths escaped in gasps.

“Hngh…!”

“I’m trying to start with this level of stimulation. Is it too weak? If it’s weak, I’ll make it stronger.”

“That’s not the issue…!”

“You’re getting angry, so you must still have some composure. Devileth, intensify.”

The vibration became incomparably stronger. My flesh changed shape like kneaded dough. The slime rotated persistently around the sensitive peaks. An indescribable sense of arousal surged through me.

“Ahhng…!”

My mind grew hazy while the vibration kept changing. With its squishy body, it twisted my n*pples then pounded them mercilessly. My body kept twitching at the wicked movements.

“Wh-what is this…! This is human anatomy practice. Hnn, stop it right now. This is weird…!”

“I already explained. I’m checking how the human body’s structure works.”

My master smiled brightly. His blue eyes captured every moment of my changing state. I couldn’t escape his gaze, bound by it like ropes.

Heat surged through my entire body and my legs trembled. My lower belly grew hot. Something tickling kept building up. The unfamiliar stimulation muddled my fading consciousness.

“I’ve been thinking about why I keep failing, and that was the problem. I didn’t know what level of stimulation was appropriate for an ordinary human.”

Even though that delighted expression made me angry, I couldn’t suppress the excitement bursting out. Without realizing it, I instinctively rubbed my legs together. The inside kept itching and feeling strange.

“Haa, ahhng, hnn…!”

“The book said that when a woman gets aroused, something called the cl*toris down below swells up. It would be nice if I could directly confirm how much it grows.”

Unfulfilled pleasure was no different from pain. My body kept heating up, but this thirst wouldn’t go away.

“Wh-when… will this end? Hnn, haa, ngh…!”

“Until I obtain meaningful research data.”

“I mean! When, ugh, is that?!”

“Who knows.”

Vrrrrm—!

The vibration intensity increased once more. Just the recoil of my body jolting with each breath turned my head into a jumbled mess. Sticky fl*id flowed from my lower half, making wet sounds.

“Ahhng…!”

I nearly lost my mind and cursed him out. My master watched me panting and answered leisurely.

“You said it yourself. That to develop the toy, I should learn about methods to please women. This is part of that process.”

Why did I ever say something like that? My mouth was always the problem.

“If that’s the case, this is already enough…!”

“This won’t be enough. Unless I check it with my own hands, that is.”

“What… did you just say?”

“If you don’t like it, you can keep doing this for days on end.”

Her master whispered softly, his devilishly sweet smile sending chills down her spine.

“So, what will it be? There’s a quick, intense method that’s stimulating but over fast, or you can stick with the slow, torturous one like now.”

How could someone this cruel and sadistic be one of the “100 Greatest Mages Who Changed the World”?

I didn’t think I could feel any more humiliated than I already did. All I could do was hope he would finally quench this burning thirst.

“Just touch it, only touch it! Anything more than that is, hngh, not okay!”

“Then excuse me.”

Master lifted my skirt hem. The movement had not a shred of hesitation. My pure white thighs that I’d never shown anyone were exposed.

I squeezed my eyes shut in embarrassment. Then I felt the chilling sensation of my underwear being pushed aside. Cool air touched my intimate skin.

“Just like in theory. They said if arousal above a certain level continues, transparent fl*ids are secreted.”

Slender, straight fingers slowly wandered around the split flesh. Sticky liquid slid on his fingertips. Then his fingers roughly stirred near the opening.

“Ahhng, hng, ngh!”

I whimpered at the shallow stimulation like being struck by lightning. The mischievously moving finger now brushed through the split gap. He rubbed the fl*id flowing from inside with his finger and let out an admiring sound.

“Clear, highly viscous. Doesn’t seem to have much smell.”

He soon put the soaked finger in his mouth and frowned slightly.

“The taste is… just so-so.”

“Ahhh! You crazy person!”

At this point, giving up on thinking seemed better. That person wasn’t the great Archmage Haliven. Not even human. Just a beast obsessed with toys.

“It’s always been difficult. But now I have a suitable specimen, so I can check as much as I want.”

He began rubbing the highly sensitive bead with his moistened index finger.

“Ahhhhng…!”

The shock turned my mind white. It wasn’t like I’d never touched it myself. But this feeling was truly a first. Much more stimulating and intense.

Then the slow finger sped up. Strange excitement and shame mixed simultaneously in the persistent gaze following me. Something hot rose like boiling soup, and soon a beast-like cry burst out.

“Ahh, ngh, uhhng, ahhng…!”

Lights flickered in my head. I flailed in darkness like someone fallen in a swamp, then was pulled back to the world. For a moment, I couldn’t see or hear anything. Then through blurry vision, I glimpsed raised lips.

“To finish from just this much.”

Admiration tinged with surprise and an unknowable smile. Shame crashed over me belatedly. I wanted to become dust and disappear. Or close my eyes and forget this reality.

But sadly, the slime attached to my chest still hadn’t stopped vibrating. As long as that thing was attached, escaping reality seemed difficult.

“Hngh… it’s over now, right? Then please release this.”

“I never said it was over.”

“Don’t lie. You just touched that… that thing!”

“But that doesn’t mean it’s satisfactory research data.”

“Th-then…?”

What had I done until now? I thought I’d thrown my whole body into extracting data with all my might. I let out an empty laugh from disbelief.

“A good idea just came to mind. Wait here for a moment.”

“What? Where are you going?”

“I’ll be right back.”

With those final words, Master disappeared. At first, I laughed because I didn’t want to believe this reality. Then later, anger suddenly surged.

How could he think to leave someone like this? Shouldn’t he at least say when he’d return? This crazy bastard. What if he doesn’t come back?

“This… insane Archmage! Go step in sh*t! And bite your tongue while you’re at it! No, that’s not enough. Waste that handsome face and become impotent for life!”

I huffed and spewed curses. But strangely, I felt a presence right behind me. The moment I met coldly chilled blue eyes, a cool voice brushed past my ear.

“Thanks so much for the kind words. You’re the first to say such things to my face. Come to think of it, you did before too. Seems like there won’t be a next time.”

It was Master. He was cursing with a smiling face. He’d clearly disappeared just before—when did he return? It was truly a short time, not even a few seconds.

“Y-you heard…? Everything?”

“What do you mean by everything?”

“Well, that’s, I mean…”

“Like calling me an insane Archmage or to step in sh*t? You also said to bite my tongue. Oh right, the most important part was to waste my handsome face and become impotent for life.”

He really heard every single thing. There was no room for excuses. I used the only method available to me now—changing the subject.

“B-by the way, what’s that in your hand?”

In Master’s hand was something wriggling. At a glance, it looked like an octopus leg, but its size and thickness exceeded imagination. Fortunately, Master’s gaze turned there.

“Oh, this? The seventh leg of an Octopus Crew.”

Octopus Crew was a high-level monster. Since rifts with monsters opened randomly, you couldn’t meet monsters as desired. Moreover, since Octopus Crew was a high-level monster, it was hard to encounter, and even if you did, it was hard to return alive.

Yet Master spoke of such a monster’s leg casually, like picking up a stone from the road.

“Where did that suddenly come from?”

“I told the Octopus Crew to hand over a leg if it wanted to live.”

“So it just gave it to you?”

“It did. Politely, on four legs. It’s pretty docile.”

As expected, Master was someone beyond common sense. How many people in the world could bring back an Octopus Crew leg like that? I had nothing to say and just blinked when Master showed a bright smile.

“Then let’s continue the practice.”

“What… are you going to do?”

“Don’t you think it would be interesting to use an Octopus Crew leg like a d*ldo?”

Accordingly, the seventh leg of the Octopus Crew in Master’s hand wriggled. Large suckers were densely attached without gaps to the massive leg.

Using that on my body?

Just imagining such a scene was disgusting and horrifying.

“No! I really don’t want that!”

“Why not? It meets all three conditions you mentioned yesterday.”

“How does that meet the conditions?”

“First, it must be big. Second, it must be powerful and move like something alive. Even if you cut off an Octopus Crew’s leg, the nerve cells stay alive, so it’s perfect. Third, at this point, it’s even sparkly and pretty.”

The Octopus Crew’s epidermis sparkled like sprinkled star dust. So I’d heard quite a few people wanted them for ornamental purposes to show off their wealth. But separately from that, using that as a d*ldo felt like losing humanity. I had to stop that at all costs.

“I… have an allergy to octopus legs! So it won’t work.”

“Octopus leg allergy? Just don’t eat it.”

“It’s so serious. I might die just from skin contact.”

Master narrowed his eyes and looked at me. Even I thought it sounded like a lie. What about the person involved? Still, perhaps because it threatened my life, he reluctantly nodded.

“Then it can’t be helped. It seemed like it would make good research data. Devileth, swallow it.”

Master threw the wriggling Octopus Crew leg. The slime attached to my body leaped into the air. The slime that had split in two merged into one, opened its mouth wide, and swallowed it.

—Nyom.

That massive leg disappeared in an instant. Devileth smacked its lips and smiled languidly.

“Did it really eat it? That Octopus Crew leg?”

“No, I sent it to my secret storage. I connected it with Devileth. It’s half-creature, half-magic tool.”

Part of me felt regretful. Just that one Octopus Crew leg would fetch a lot of money. Maybe I should have made a different excuse.

“Then we should continue the practice.”

“What? Wasn’t this enough?”

“Not yet. We have so much research to do.”

Master, who insisted on sitting me back in the chair, tormented me terribly that day. How long it took for a human to reach *rgasm at maximum speed. And how much larger the cl*toris grew when at peak arousal—he measured it all.

Beyond that, he said he’d experiment with the fl*ids I’d secreted and used the slime to absorb it all. During that process, I reached cl*max once more and whimpered softly in shame.
