The Breeding Tutorial
Vibrating Pussy is manifesting.
We reached the Breeding Facility.
Maybe because the building was built like a motel, the inside was exactly what I'd pictured: one long corridor with rooms running in a straight line from Suite 1 all the way to Suite 10. Casey and I took the innermost of them and stepped into Suite 10.
Creeeak—
"Whoa..."
"Tch..."
A king-size bed. Dildos and whips packed edge to edge along the walls. Contraptions I couldn't even put a name to. Just standing still in there was enough to get me stupidly hard.
"Take off that pussy cover and get on the bed. Face down."
"Pussy cooover?"
"Yeah. The thing you've got covering you down there."
"Haa?! This isn't a cover, it's a gainer, you idiot~"
Casey didn't bother hiding how put out she was, but whatever that earlier "correction" had done to her must have stuck. She didn't actually fight me. The mesugaki climbed onto the bed, flung the cloth aside, and lay face-down on the mattress.
"......"
An elf really was an elf.

Snow-white skin. A perfect line running from that narrow waist out into her hips. And because she was prone, even her pink pussy was out in the open, bare as anything.
Throb—!
My cock swelled just a little more.
My turn to strip. I stole a glance at her, then eased my waistband down.
Slip— rustle!
I stood right in front of Casey's ass, idly working my erection in my hand.
"Is it really okay to just... do it?"
The breeding tutorial will now begin.

◈ Phallus Enlargement (Lv.1) — For 10 minutes, cock size increases by 1.5× (scales with level).
The massage I could live with. But Phallus Enlargement? From the name straight through to the effect, it was vulgarity pushed to the absolute limit. Still, I wanted to see it at least once—my trusty little guy, blown up into a porn-tier monster cock.
"Guess I'll... try Phallus Enlargement first."
In the end I couldn't swallow the curiosity, and I shouted the skill name in my head.
Phallus Enlargement...!
In that instant, something impossible happened between my legs.
Using skill Phallus Enlargement.
BWOOOOM!!
"Holy shit—ngh?!"
Girth was girth. Length was length. My cock had swollen until it was as thick as my forearm. The old me hadn't exactly been something to apologize for, but this had left human specifications behind entirely.
"Whoa... this thing's gotta clear ten inches, easy."
I stared blankly at what I'd become, then looked back down at Casey, still face-down on the bed.
Gape— gape—
The mesugaki's plump pussy. Slick was seeping from the seam, popping little bubbles as it went.
"Is it just... leaking out of her on its own...?"
At my mutter, Casey turned her head a fraction.
"Why aren't you starting alrea—hwaaaah...?"
The second she saw how huge I'd gotten, her face went red. She buried it in the pillow again and mumbled into the cloth.
"I'll never forget this... you thick-headed human, you dull-witted humaaaan... hyk!"
Pssht...!
Her mouth was running filthy-arrogant, and yet her pussy was already drooling on instinct, slicking itself to take me.
I brought the enlarged cock up between Casey's lips.
Thump—
"Hoohk...!!"
The moment the tip of my glans touched skin, her ass flinched. I dragged myself slowly up and down along the soft fold of her, just the outside.
Slick, slick—
"Ngh...!?"
"Hweh... d-don't rub iiit...!"
I was only grinding on the outside, and it was still so soft I thought I'd lose my mind. It felt incredible.
Skrt, skrrt! Tok—
"Hyit...!"
After a few dozen passes back and forth, I felt something like a little nub pop free up top. Her clit. I gave that bead one good rub.
Shk-shk-shk—!
"Haa...!? Hwaaaahk♡!?"
Casey reacted instantly.
Squirt—! Jolt, jolt...♡!
"Hooohk...♡"
Her waist flopped back and forth like a fish still alive on the cutting board, and my cock ended up smeared in her slick. That was enough rubbing. Time to actually put it in.
Except I was twenty. I'd watched a disgusting amount of porn, and I'd never once done it for real.
Where am I even supposed to put it?
I hesitated, then caught the plump lips on either side of her pussy in my hands and spread them wide.
Squelch—! Fwip!!
"Nnghok?!"
The flesh pulled taut, and the pussy-juice pooled in the seam flicked out in a little spray. Once I had her opened up, the bright-red hole that had been hidden underneath showed itself.
"Found it."
It sat a lot lower than I'd expected. I set the tip of my glans to the hole and pushed in, slow.
Grrrk—grrk—!
"Ah... ah! W-wait a se—!"
Unbelievably tight. I wasn't even halfway in, and the grip was no joke. But I couldn't stop here. I put everything my hips had into the thrust and drove up.
"Hrrk—take it!"
Puuuush—!!
"Hwaaaaaahk♡!!!"
A moan so filthy it barely counted as a sound, and my cock punched clean through the mesugaki's narrow pussy to the hilt. And the feeling of being inside a woman for the first time—
"Ohh... i-it's warm, it feels so good..."
"Haht... y-you're like a beast...!"
Yeah. Warm, and the squeeze felt good. And then, right at that moment—
Mesugaki Elf Casey's 19+ trait Vibrating Pussy manifests.
As if her cunt had swallowed a phone set to vibrate, the walls clamped around my cock began to tremble.
Brrrrrrrrrr—!!!
"Ghhhaaak!!"
This wasn't a pleasant buzz. It was a sharp, electric tingle, like my glans had been shocked.
Brrrt! Viiiiing!!
"F-fuck!"
"Heh...♡ Just as I thought, you th-thick-headed human..."
Casey, still face-down, turned her head at the sound, lifted the corner of her mouth, and laughed at me.
"So why'd you go and stick it in me without asking...? Heojup~♡"
Tears were still standing in her eyes, and she was running her mouth like none of it touched her.
"C-Casey... s-stop!"
"Heeh? Stop what, exaaactly?"
"The hole! Tell the hole to stop vibrating!"
"L-like this? Haht~"
Casey's ass went rigid. Then—
Sqqqquelch!!!
The vibrating walls themselves started squeezing my cock even harder.
"Gyaaaahk!!!"
"Hyut...! Kihhihit..."
A grip that had lost its mind. A vibration function that melted my brain. And on top of that, the mesugaki's sweet body-scent, stabbing the tip of my nose over and over.
Throb...!!
Fuck. I hadn't even been inside her a full minute, and my balls were already drawing up. At this rate I'd blow my load without landing a single thrust and graduate as the Premature Monarch.
I'm cumming in a few dozen seconds either way.
Then it was all or nothing. I seized Casey's stiffened ass in both hands and hauled my hips all the way back.
Schluuuk—! Brrrrt—!
"W-where do you think you're running? You caaan't...!"
"Ghk! Just—!"
The tight walls clung wet and sticky to my glans, like they refused to let go. I barely, painfully dragged myself out until only the head was hooked in her entrance.
"Y-you started it... I'll pound you like a bitch."
"Whaaat?"
The gentle part was over. Mesugaki! I braced my hips and slammed roughly toward Casey's womb.
SMACK—!!!
"Hooohk—!?"
The wet clap of pelvis meeting ass. Casey's head snapped back, and her eyes met mine.
"Heeh...? Eeh...?"
They weren't focused. One good slam and the mesugaki's mind had briefly left the building.
Now!
I pounded her pussy without a pause for breath.
Smack—!! Squish-SMACK!!! Thrust!!
"Ook!! Hooohk!! Nnhwaaaahk♡!"
Pssht!! Fssssht!!
Every time I snapped my hips, pussy-juice sprayed in every direction from the seam where cock and cunt were joined.
Smack—! Squish... smack—!! Viiiiing!!
"Ghk... pussy, just hold still for a second!"
"Hwaaang...!! I don't wannaaa...! Haahk!"
I wanted to keep slamming into that mesugaki pussy, but I was at my limit too. For the last one, I drove my hips in like I meant to wreck her womb.
SMAAAAAACK—!!!!!!
"Hwaaaahk!!!"
"Ghk... I'm c-cumming!"
And I let go of the semen I'd been holding back.
Brrlt—!! Splurt-splurt-SPLURT—!!!!
"Oh... hooohk...♡"
The moment I poured it into her, Casey hiked her ass high and trembled all over.
Ejaculation in progress!
Use the skill Follicle Massage to maximize pregnancy chance!
Right then—maybe it was the system's doing—one side of Casey's lower belly began to glow, faint and soft.
Is that the spot I'm supposed to massage?
I let go of the ass I'd been gripping and slid both hands under her stomach.
Using skill Follicle Massage (Lv.1).
And I pressed into the glowing patch of her lower belly, firm little circles, clockwise.
Knead, knead—
"Don't press there...! You caaan't...!!"
"What do you mean can't. Let it out. Be good."
The longer I kept at it, the more I could feel the walls that had been taking my cum inside her start to tremble harder.
"Ovulate already! Give me the egg!"
"I-I don't wanna!! Nnghh... it!"
Pop—!
In the end a small sound escaped from Casey's belly.
Ovulation successful!
The egg has been released.
Fertilization chance: 91%
Casey clutched her lower belly and shook.
"Y-you sex-offender bastard... forcing out even my egg..."
Deep in her belly, the egg she'd just ovulated was probably already sinking into the sea of semen I'd poured into her. I milked the last dribbles still leaking from the tip, then pulled out of Casey's pussy.
Schluuuk... plop!
The engorged hole gaped, and the cloudy cum that hadn't managed to fit drooled back out of her in thick strings.
The sperm squadron is searching for the egg.
A virtuous egg is fleeing! Sperm in pursuit!
Egg suppressed... Fertilization successful!
"......"
Wow. Look at that notification. The wording made it sound like I was in the middle of a violent felony. Anyway, the pregnancy itself looked like a sure thing.
Something like golden powder burst out around my body.
Fwaaah—!
"Ooh!"
I even felt my body get just a little lighter. All I'd done was wreck her once, and I leveled up. A truly god-tier class, no two ways about it.
My eyes went back to the bed.

The cocky mesugaki wasn't there anymore.
"I have to get the semen out..."
Just one female, sprawled where pleasure had completely broken her. Looking at her like that, a little guilt finally caught up with me.
"I feel... kind of bad."
Breeding Monarch or whatever else I was, this hadn't been proper sex—the kind where two people actually met each other—and on top of that, I'd gone and knocked her up.
A fertilized egg belonging to Master Ja Jihwan has implanted in the womb of the mesugaki elf, Casey!
Time remaining until birth — 10?
"The fuck?"
Ten months, right? Implantation had taken all of a minute, but the term until birth was more realistic than I'd expected.
Flick, flick—!
I waved the windows away with a rough swipe of my hand. Come to think of it, how much time had passed?
Back when I'd still been gaming in my studio, it had only been around three. Sex really did make the time fly. I picked up the underwear and pants that had fallen under the bed and pulled them on, more or less.
"Casey. Wash up a bit and get some rest."
"Oh... oohk... haaaht..."
Casey didn't answer. She just couldn't get her shaking legs under control, and the only sound coming off her was the obscene one of her pussy spitting semen back out.
Glug... squirt!
Seeing a person broken down that far only made me feel worse.
"Ahem... I'm going..."
I read the room for a second, then slipped out of the Breeding Facility like I was fleeing the scene.
[ ! ] A system error has occurred.
Analyzing... Analysis complete!
Applying the time system of Dimension 219, Planet Earth.
Time remaining until birth — 10?
BEEP—!
