"Purity? That's insane.

"So that's why I suggested we take a bath... In our tribe, when a wandering male elf visits from outside... if we like him, we indirectly propose by suggesting a bath..."

I'd sensed something unusual in the atmosphere and had my suspicions, but... she swore this to the World Tree?

"But Mister... I can't do anything without proper knowledge. I need some basic information first."

"You don't need to go to an elder elf. I can teach you."

Well, since things have come to this, there's no reason to back out. Only a eunuch would retreat now.

"You? Do you know about these things?"

"Yes. Though my academic credentials fall far short of yours with your advanced degree, I do know a little about this area."

"In that case..."

Ismera swallowed hard.

"Please teach me..."

"First, take off your clothes."

"Alright... Please don't look..."

As I turned around, I heard rustling sounds behind me. It was Ismera removing her clothes.

"Now you can look at me..."

When I slowly turned around, I was left speechless.

Ismera's golden hair captured the moonlight, emitting a subtle glow in the breeze.

Her green eyes sparkled with a deep, serene light reminiscent of the forest's depths, seeming to guide onlookers into an infinite woodland maze.

Ismera's body was elegant and harmonious.

Her waistline flowed smoothly like a river current, and her full breasts trembled delicately like flower petals.

Her skin, reflecting the moonlight with a lustrous sheen, seemed to convey its silky texture even without touch.

Between her legs, which extended in smooth curves like a straight-grown tree, existed an ineffable mystery and delicacy.

Ismera's body, blending with nature, radiated a quiet charm like a lyrical poem.

This was my first time seeing an elf's naked body.

I can declare with certainty that among everything I've seen or will ever see, nothing could be more beautiful than this.

Under my gaze, Ismera's face flushed deeply as she mumbled:

"Please... your private lesson for an ignorant elf who knows nothing..."

"Come closer."

As Ismera approached unsteadily and stood before me, I tried to embrace her.

But my already aroused lower half jabbed against her stomach.

Ismera looked down between her fingers with a bewildered expression, and her body froze.

"Kyaaaaaaah!!"

Then she screamed shrilly and frantically backed away.

"W-what is that!?!?!?!"

"Oh, I'm sorry. This isn't something I can control."

Seeing what was standing at attention, Ismera's face turned pale.

"Is-is that some kind of parasite!?!?!"

"No, this is a human male's sexual organ."

"Sexual organ?! What on earth?! Are you saying you've been walking around the academy with that large, hard thing attached to you?! Are you insane?!"

"It's not always like this. It only gets big when I'm excited. There's nothing strange about it."

Ismera, who had been clutching her chest and panting, slowly approached me again after a moment.

"So this... is your sexual organ..."

Ismera slowly crouched down and examined the veiny thing intently.

"It looks like a mushroom that grows near the Great Forest. Though not nearly this big... Does it contain poison?"

"Of course not. Human women touch it, hold it, and even suck on it."

"Gasp?!"

The color drained from Ismera's face.

"Why...?"

"Because it feels good. Want to try?"

After staring at mine for a moment, Ismera stood up again and shook her head.

"I'm sorry... let's just bathe and go back today... I'm suddenly not feeling well..."

"Not feeling well? Are you sick?"

"Yes... After seeing your thing, my body feels hot... and there's a tingling sensation below my waist. I think I might have a fever..."

Now I noticed that Ismera's face was flushed, and sweat was beading on the bridge of her nose.

"You're feeling hot?"

"Hnngh?!"

When I touched her forehead and cheek, Ismera moaned and curled her body tightly.

"D-don't touch me! It feels strange!"

"Ismera, this isn't sickness..."

I started to explain but stopped. What was the point of explaining everything to Ismera, who was completely uninformed about these matters?

"Mister!! What are you doing!!!"

I embraced Ismera suddenly.

"Seeing is believing. Let's learn through experience."

When I laid her down on the grass, Ismera tried to curl up like a pill bug.

I grabbed her wrists and ankles, spreading them apart, and a moan like an exclamation escaped Ismera's lips.

"Mister..."

"We must keep the Oath of the World Tree."

At my words, Ismera flinched but finally spread her legs herself.

"Please... give me your private lesson..."

# # # # #

At first, Ismera could clearly feel everything.

Being carried from the pond by Dian, laid down, and allowing him to do as he pleased with her body to fulfill the Oath of the World Tree and to have him.

Then Dian embraced her and kissed her, and was that when it started? Ismera's consciousness began to blur.

Her first kiss was so ecstatic that even with her eyes closed, the invisible sky and earth seemed to spin like a clock.

Suddenly feeling something hot welling up inside her like she was about to cry, Ismera unconsciously wrapped her arms around Dian's neck and extended her tongue.

The sensation of their tongues intertwining was so electrifying that Ismera almost bit Dian's tongue.

I think I'm becoming addicted to kissing...

Lost in ecstasy, unaware that saliva was dripping, Ismera rubbed and sucked on his lips, feeling an acute sense of deprivation when Dian finally pulled away.

"Why did you stop...?"

"We need to move to the next step."

"Ah!"

When Dian moved down and suddenly took Ismera's nipple in his mouth, she twisted her waist violently, unable to resist.

Though Dian was stimulating her nipple with his teeth and tongue, for some reason, she felt a sudden response far below in her groin.

This must be urine. It must be urine coming out!

Not wanting to embarrass herself in front of Dian, Ismera tried to excuse herself to relieve herself in the bushes.

But she couldn't.

Because Dian, still holding her nipple in his mouth, inserted his finger between Ismera's thighs.

When the tip of Dian's finger touched Ismera's deepest, most intimate place, she bit her lip and threw her head back.

"Ismera. You're getting very wet."

"Don't say... such... ahh!"

Dian's fingers mercilessly violated Ismera's valley, which was soaking wet with slippery fluid.

Experiencing this incredible sensation for the first time, Ismera twisted her body in suppressed silence like a deer shot in a vital spot.

"Ugh...! Ungh! Mmph...!"

The world's most elegant race was now writhing with primitive pleasure on the grass in the middle of the night.

"I'm going to put it in now."

"What, what are you going to put in...? No! No!!!"

Looking down with hazy eyes, Ismera suddenly came to her senses and shouted.

Dian's enraged mushroom was about to enter Ismera's body!!

"You can't put something that big in! Wait, Mister! Please wait!"

Ismera pushed against Dian's chest desperately, pleading.

"Please wait here for a moment! I'll go ask the elder if this is really okay! Please, I beg you! Since I'm ignorant about these matters, I should first seek advice from the elder and after that...!"

Ignoring everything, when Dian's mushroom finally forced its way in, Ismera could speak no more.

At first, Ismera was pinned down underneath, mercilessly pounded.

By this point, Ismera's body had already left the control of reason.

Every time Dian thrust deep inside her, the impact traveled all the way to her brain.

It hurt, but at the same time, the extreme pleasure made her eyes water, and Ismera unconsciously wrapped her legs tightly around Dian's waist.

After ruthlessly pounding Ismera for quite some time, Dian switched positions.

Finding herself on top, Ismera momentarily tried to escape, but Dian grabbed her waist and pulled her down, not allowing it.

After bouncing like that for a while, Ismera eventually crouched down, drooling and frantically slamming her hips down.

Then Dian's body trembled as he released something hot abundantly inside Ismera's body.

"Your essence, Mister... this precious thing..."

In a dazed state, Ismera licked up all the fluid that flowed from her opening onto Dian's stomach.

Ismera couldn't understand what had possessed her to do such an outrageous, vulgar act.

After licking his stomach, Ismera moved down and took Dian's mushroom deeply into her mouth.

The salty, full sensation was enough to drive both Ismera and Dian crazy. Rapidly, Dian's mushroom prepared to release spores again.

This time, Dian made Ismera get on all fours and attacked from behind.

It was the same position as stray dogs mating in downtown alleys—practically an insult to a noble elf.

The normal Ismera would have exploded in anger, but now was different.

Realizing she was being treated like an animal by Dian, Ismera was overcome with an uncontrollable sense of depravity and excitement, and in reaction, she forcefully squirted clear fluid.

Like urinating against a street tree, she had truly become a female dog.

In this moment, Dian was the advanced scholar, and Ismera was an uneducated illiterate without even basic education.

The sounds coming from her mouth were no longer human but animal whimpers.

This is as far as Ismera clearly remembers. She has no memory after that.

It's not that she has no memory, but rather that her consciousness blurred from the sensations storming through her from head to toe, making it difficult to recall properly.

The heavy feeling pounding her lower abdomen, the shame and guilt of urinating on Dian's body multiple times, the dizziness and floating sensation as everything went white before her eyes, and the unstoppable wave-like pleasure.

Dian's firm body and their shared heat, the exchange of slippery fluids, and the "private lesson" progressing gradually through various positions she couldn't have imagined.

"Mister, Mister..."

Ismera shook Dian's chest as he lay flat.

"Mister... you can still do more..."

Like a thief who learned late and doesn't notice the dawn.

Ismera's desire, having learned womanly pleasure from Dian, didn't cease even as the day changed.

"I can't do any more... Nothing's coming out anymore..."

"Mister... I'll help you, so please gather your strength..."

Ismera went down, almost crawling, and slowly licked Dian's organ.

Ismera, being fundamentally intelligent and highly educated, has excellent learning ability.

So in just one night, she mastered how to revive Dian with her mouth and tongue, and under Ismera's skilled oral technique, Dian's lower half stood at attention once again.

"Haa, Ismera... This is really the last time..."

"Hurry. My thirst for knowledge hasn't been quenched yet... Please proceed with the advanced course..."

Filled with ecstasy, Ismera embraced Dian with her entire body, smiling with completely relaxed eyes.

Soon Dian was persistently thrusting into Ismera's depths.

Ismera's body began to convulse wildly and squirt streams of fluid.

This continued without pause until dawn, as the eastern sky gradually brightened.
