What the Hell Are You Doing Right in Front of Everyone?!
The elf's words came out in a silky tone, as if she were leisurely running her eyes all over my body from head to toe, making my skin crawl.
Someone in the front row immediately shot up a hand and blurted out, "Weren't we sweating too?"
"Exactly! Of course we were sweating! That's how we climbed all the way to the top of today's food chain! By sweating, we developed our own body-temperature regulation, so no matter where on Earth we fell, we'd still have the superb adaptability to survive!"
Her eyes narrowed again, this time locking straight onto the thick bead of sweat sliding down my neck toward my chest.
"All the other animals on Earth had those sharp teeth, claws, and horns, but since they couldn't regulate their own body temperature, their activity levels were always lower. You beastkin folks can relate, right?"
The beastkin's ears perked up in unison. One wolf-eared beastkin sitting at the side let out a long tongue like she was panting from the heat, then casually stuffed the whole thing back in.
"But humans were different. Without any natural weapons of our own, we relied on that massive brain and those hyperactive sweat glands to cool ourselves off, letting us regulate body temperature far more efficiently!"
"What are you staring at? Ahahaha!"
My foot was crushed again.
I wanted to say something more, but it was a lecture, so I just kept my mouth shut.
"Isn't that fascinating? Just a little sweat-gland development was enough to put us at the front of the survival race and even let us reach the pinnacle of all living things?"
As she spoke, the elf stealthily circled behind me, hiding her body while continuing her lecture.
She tapped my shoulder with the pointer stick in her hand.
"But that's not enough. Just sweating a lot or being more active doesn't protect you from predators. Here, humans evolved again. That evolution was… hey, raise your arm a little!"
"I didn't say to just stand there!"
"Hmph, that's what I mean—raise it a bit. It's these shoulders! Shoulders evolved to throw things hard and fast!"
Since I had clearly misunderstood her, I was stuck in that awkward pose with my arms behind my back, offering my bicep like some bodybuilder flexing, thanks to the elf's firm grip.
"See? Isn't it amazing? These shoulders are just the right amount of muscle—no more, no less—and compared to other species, they're basically matchstick-thin. Yet they elevated humans to the top of the food chain!"
"…?"
She stroked my shoulders and arms in slow circles.
I knew this was all part of teaching the students about human evolution, but after everything that had happened with Dyna and that crazy scene earlier, the elf's actions felt… dirty.
"These shoulders gave humans the power to throw from a distance. Thanks to that, we could hunt prey far away or protect ourselves from bigger, fiercer predators than we were!"
The strange sound of her heavy breathing came from right behind my neck.
She must have leaned in close, trying not to smell the sweat on my skin. Trying to hold her breath… or something.
Curious, I tilted my head just a little—only for two heavy, weighty pockets to slam down on my back.
"Professor Celestin?"
"Shhh! It's a lecture. How many times do I have to repeat myself for you to get it?"
Her voice slipped into my ears as if her face was right on my shoulder.
Still pressed against my back, she let out a tiny fart—actually farted—then immediately started groping all over my body again.
"From there, it was smooth sailing. As time passed, humans learned how to train their bodies thanks to our superior intelligence. Just like you see now—efficient muscles and perfect physiques!"
I'd heard somewhere that humans first figured out body training during ancient Roman times.
They even held a meeting to boost the coliseum gladiators' win rate and came up with weight training, right?
The elf kept touching my chest and lightly caressing the faint abs that had started forming on my belly, as if daring the students to pay attention.
"And that's why we became the apex of all living things. Civilization grew, so we kept having children to keep the labor force going, causing our population to explode!"
She started trying to tug my pants down. I grabbed her hand urgently, but she ignored me and kept pulling, grunting the whole time.
"And even with that explosive population growth, there's one more secret: this… reproduction… Hey! Let go?!"
"You want to lower my pants right here?!"
Everyone's watching! What the hell are you doing right in front of everyone?!
Now that I'd seen it all and was completely numb to the shame, I wasn't embarrassed anymore—but that didn't mean I was okay with it.
I struggled hard.
"We're supposed to talk about human reproduction! Just cooperate!"
"Just say it! Why are you trying to strip that pervert's pants?!"
"Didn't you hear that 'seeing is believing' is better than hearing it a hundred times?! Just for a second—please!"
Despite the power gap, the strict master-slave dynamic left me no choice. I had to let go. The elf took the chance, shoved my pants down in one go, and shouted, "There—!"
"Kya?!"
"P-professor! Even if it is, still…"
"Quiet! The chance to see the reproductive organs of the last remaining human on Earth doesn't exist anywhere else! Only right here! Stop thinking about shame in the face of academic progress!"
"That's you who's taking them off!"
Who would ever think I'd happily strip just to advance learning?
"So many words. In this opportunity, let's correct your arrogant attitude… No, wait. Actually, showing everything like this is a bit much, isn't it?"
The elf had been glaring at me fiercely, but something in her mood seemed to shift.
She kept glancing between my crotch and the students, probably deciding that even showing her panties was too much. She reached over my boxers and traced the outline of my erection.
"Professor Celestin! What are you doing?!"
"You're imagining getting pregnant, aren't you?! Hand—"
Chaos broke out again among the elves.
Some were blushing furiously and throwing themselves face-down on the desk. Others were yelling at each other. One looked like she was about to cry. Just one pants removal had turned the lecture hall into a circus.
"Now, now, everyone, calm down! You guys are really stimulated, aren't you? If I could, I would've shown you human reproduction methods firsthand, but since you're this shy, we'll stick to imagination today… I suppose?"
"Damn it!"
She actually pulled my panties down too!
"Kyahaaaaah?!"
"Oh my god!"
"Elephant! Why is the elephant trunk down there?!"
"There wasn't much fur anywhere else, but right there… is that a mammoth?! The smell… the smell!"
The elf casually dropped a bomb, and the entire class fell into total panic.
While the elves were squealing and blushing, the beastkin were staring at my crotch with pure curiosity.
"Well… if that's the case, I guess it's fine."
"So that's why the human population reached billions…"
I actually felt a little sympathetic toward the shy elves, but it didn't make me feel any better.
Looking around at the noisy lecture hall, the elf shouted again.
"Quiet! Human reproduction isn't that different from ours! We stimulate the genitals until they harden, then directly plant the seed deep in the female womb! It's that simple!"
"Why are you so calm while groping someone else's dick?"
"Eh? Of course I should show the climax too. This is part of the lesson—how much seed we shoot! Any problem with that?"
"…"
A lot of it.
Instead of saying that, I started thinking about how I was going to get revenge on the elf later—only for
Thump!
"Kyaa?!"
"Huh?"
"S-stop moving! Everyone can see…!"
The soft fabric against my back vanished, replaced by something sharp poking my spine. At the same time, the startled elf yelped.
"Ah, yeah… your chest really is huge. Guess you got the short end of the stick with that destiny."
"I can't stay still?!"
Finally, after enduring all that mischief, the elf received heavenly punishment and let out a red-faced scream.
