Sex Ed with Virgin Valkyries in the Divine Realm!
A brilliant golden flash fades, and Kang Hanul's vision fills with a grand, sacred temple.
"Hraaah!! You kidnappers!! Show yourselves right now!!!!"
One idiot shadowboxes the air. And gazing down at that moron from above...

'Arrogant Goddess of Holy Judgment' (Astraia)
The empress sits upon her jade throne. With her wings fully spread behind her, she looks like she's striking quite the pose. The problem is that her audience is Kang Hanul.
"Ahem. Ignorant mortal. I have personally summoned you..."
"Whoa! It's a boss monster!!"
Kang Hanul points straight at the empress without a second thought.
"B-Boss monster?! You worm! I am the noble Empress of Holy Judgment, Astraia!!"
"Ooh? Auntie? Why's the auntie from my head popping out there?!"
Crack! A thick vein bulges on Astraia's forehead. Calling a great constellation "auntie." She could split this punk's skull open and it wouldn't be enough, but she suppresses her rage.
"Haa, fine. Listen up. You know your Rapid Breeding trait is disrupting the order of the mortal realm, right...?"
"No clue!!"
"......"
"That seed you're irresponsibly shooting everywhere!!!"
The empress bellows thunderously, but Kang Hanul picks his nose and mutters nonsense.
"Seeds...? Like the sunflower seeds in chicken breast fried rice?! I ate all of those!"
"......"
No surprise—this guy's brain couldn't grasp it. Astraia takes a deep breath and decides to probe with a basic question. She needs to gauge his sexual knowledge level.
"Haa... fine. Then you... do you know how babies are made?"
'He's shoved it in every hole and even made kids, so he must at least know about sperm and eggs combining.'
But.
"Of course I do! Babies are brought by storks, right?!"
"......"
The empress clutches her face with both hands. To think this level of intellect has been blasting seeds into an otherworldly princess and a Special Grade Hunter's pussies.
'This guy... he's beyond imagination, a total musclehead idiot...'
She judges that without basic sex ed and ideology, he'll go right back to "training" and impregnating females in the mortal realm.
"This won't do... Valkyrie."
Whoosh!—!
"You called, Your Majesty?"
At her gesture, three Valkyries zip in at light speed and kneel.
"Drag this ignorant beast to the Divine Realm's Valkyrie Training Hall immediately and install at least the minimum intelligence!"
"By your command!"
The Valkyries rise and grab Kang Hanul's arms.
"Whoaaa!! Let go! I'm a Martial Artist! I'll walk on my own two feet!!"
The flailing Kang Hanul gets dragged out of the temple.
Divine Realm Sector 3, Valkyrie Training Hall.
This is where fresh adult Valkyries learn divine laws, regulations, and "Union of Life" (sex ed). Union of Life is a liberal arts course only available right after becoming adults.
Creak!—!
"In you go!!"
The Valkyries kick Kang Hanul in the back, shoving him into the massive lecture hall.
"Gyaaack!!"
Kang Hanul lifts his head from the floor, and every gaze in the packed room of Valkyrie trainees locks onto him.
"Oh... a guy?"
"A male from the mortal realm...!"
"His scent... that smell is no joke..."
Ding-dong!
Then, the class bell rings.

Creak!!
"Hey!! Quiet down, everyone!!"
The professor with silver hair in a neat bun slams her baton on the podium as she enters. Her name is Arian. She pushes up her glasses with a stern expression, but her tight suit skirt boasts hips ready to burst—quite the lewd figure.
She probably doesn't know who Kang Hanul is or why he's here. Just an order from the empress to educate a delinquent male.
"A human from the mortal realm has joined. By Her Majesty's special order—ignore him and focus on class. You, sit in the back row."
"Ooh! Got it!!"
Kang Hanul salutes smartly, plops into an empty back-row desk, and pulls out parchment and a quill from beside it.
'Martial Artist Kang Hanul! I'll absorb these teachings like a sponge!'
Ignoring the idiot who thinks he's here to study, Arian's class begins.
"Today is theory on fertilization and implantation."
She starts chalking a [cross-section of male genitalia and female uterus] on the blackboard.
"When the male's yang enters the female's yin, guide the glans tip to the cervix! Pour the seed deepest inside for smooth fertilization and implantation."
"Kyaaah!"
"P-Professor... that's too explicit..."
"So naughty...!"
The innocent virgin Valkyries blush, cover their cheeks, or giggle shyly as the lesson continues.
But our protagonist Kang Hanul's reaction?
"Huff...! Deepest inside...! Note... notes!!"
Learning theory for what he's done on instinct opens a whole new world for him.
Then, something clicks wrong, and he tilts his head.
Scribble...Pop!
"......?"
Arian, mid-lecture, and dozens of Valkyrie students all turn to Kang Hanul as he stands.
"What is it? A question?"
As everyone stares puzzled!
Thrust! Thrust! Thrust!
"Hut!! Hut!! Hut!! Hraaah!!"
This guy suddenly starts air-pistoning!
"Kyaaaaah—!!!!"
"Wh-What the hell is that human doing!!"
Thrust! Thrust! Thruuust!
"Haht! Hut! Heh-heh-hut!"
Right in the sacred Divine Realm classroom, a male performs "shadow mating." Valkyries scream and cover their eyes, but some peek through fingers, drooling at the vulgar hip snaps.
Huff... huff...
After snapping his hips dozens of times into the air, Hanul sits back down with an enlightened "Aha!!" look.
"......!!"
Arian watches the moronic display from the podium. Her eyes shake.
'Th-That... that's a human male's size...? Impossible...'
As a professor of life creation, she's seen countless texts and diagrams, but that out-of-spec natural cock flopping before her shatters her common sense.
'Can't lose my dignity as professor... Calm down, Arian.'
She steadies her trembling voice.
"H-Hem! Q-Quiet down! Class continues! Ignore that human's... behavior!"
She slams the blackboard to resume, but steals glances at Kang Hanul's lower half whenever she can.
Buuuuuurp—!!Twaaaang!!
Because Kang Hanul is rock-hard, tenting obscenely through class.
"The male seed reaching the uterus... haa... charges toward the egg... hngh, and upon implantation..."
As the lesson drags on, the classroom air thickens. Maybe from the air-pistoning.
Kang Hanul's sweat and male musk heats everything up. Nearby Valkyries stop watching the board.
They just fixate on his massive cockhead bulge.
Squelch... squish...
Valkyries clamp thighs, rub them together, or grind hips secretly on chair edges, whimpering.
Ding-dong!—!
The sacred end-of-class bell rings.
"Cl-Class dismissed! Everyone, go!"
The professor blurts desperately, and—
Stampede-bang!!
"Move!! B-Bathroom!!"
"Haa... haa... hurry...!"
Valkyries bolt without grabbing books, clutching throbbing pussies as they flee.
Huff... huff...
Arian hastily packs her materials. No time for professor pride—she needs to escape before begging for cock on all fours.
'Dangerous... back to my lab quick... fingers to calm down...'
But.
"Ooh!! Professor!! I still have questions!!"
Kang Hanul, massive tent leading, blocks Arian's back-door exit.
"Eek?!"
She startles and stumbles back.
"M-Move! Class is over! Questions next time..."
"It's important!! When the seed charges the egg, do you spin and strike?! Or thrust like spear arts?!"
A brain-dead moron question.
The pussy-exploding horny professor feels her guts twist, but blurts anything to escape.
"Ch-Charge! J-Just shut up and plunge! Now move!!"
Arian brushes past, but—
"Then when releasing seed, do you yell 'Hraaah!!' to shoot farther?!"
"Sh-Shut... l-later...!"
As her pussy threatens to burst, she tries fleeing without answering.
Grab!—!
"Where you going?! Questions ain't done!!"
Kang Hanul absentmindedly grips her slim arm tight.
"W-Wait...!! Ahhnngh…!!!"
Squiiiirt!!
From her soaked skirt-trapped pussy, pent-up juices gush uncontrollably.
Buck-buck...
"Haa... haa... aaahn...!"
Arian orgasms standing, hips jerking back and forth.
'No... limit... can't hold back...!'
Reason succumbs to lust. Unable to endure, Arian yanks Kang Hanul's hand.
"F-Follow me! Can't explain here... I'll finish in my lab...!!"
"Ooh!! Lab!! Professor's the best!!"
The clueless idiot gleefully follows.
Arian's private lab.
Click!
Kang Hanul enters, picks his nose, and looks around.
"Ooh~! Sooo many books!! You explain here?!"
"Y-Yes! Stand there a sec!"
While he blankly eyes a wall painting—
Sliiide...Plop.
Arian ducks behind her desk and flings off her drenched panties without hesitation.
'That size... my tight hole can't handle it... gotta loosen up or it'll rip...!'
She shoves three fingers into her pussy entrance, trembling.
Squelch... squish!
"Hngh...!"
Three fingers in, but she shakes her head.
'No... not enough room. At least fist-sized...!'
Arian bites her lip and forces her fist into her narrow pussyhole.
Squish—!!Splort... squelch!!
"Hnnngh...!!"
DIY pussy expansion.
Squelch! Scriiiich!! Squelch!!
Pussy juices spray, filling the lab with vulgar squelches.
Then, Kang Hanul turns.
"Professor! That implantation thing... what was it again?"
Arian answers in her embarrassing pose, fist deep in pussy.
"Haa... haa... that's when... ngh! the seed takes root deep in the field... hngh!"
Her free hand waves mana—
Shrrk—clack!Click!
Blinds drop, door locks.
Squiiiish... pop!
Arian pants, pulling out her hand. Pussy expansion complete.
"Ooh!! Thanks for explaining! I totally get it now!!"
Satisfied, Kang Hanul nods and heads to the door, twisting the knob.
Click-click!
"Huh? Door won't open!!"
Of course not, idiot. Horny virgin professor pussy cast soundproofing and locked it.
"Where do you think you're going? My lesson isn't over."
A stickier voice comes from behind.
"Did you really understand my answers?"
"Uh...? Y-Yeah..!!"
"Then answer this. When a male yang rubs a Valkyrie's stigma at a 47.5-degree angle, name the three mana backflow phenomena from the third cervix!"
"Stigma...? Backflow...? Uhh...?!"
Brain-capacity-exceeding nonsense.
As Kang Hanul stammers, Arian smirks knowingly.

Squelch...
Now fully nude, the former-suited professor hops onto her desk, spreads wide toward Kang Hanul.
Her expanded slutty hole drools clear nectar.
"You can't fully grasp life's mysteries with theory alone."
Arian adjusts her glasses.
"Time for supplementary lesson... hngh...!"
She spreads her pussy, beckoning him with a finger.
End of Chapter 13!!
