First Experience
In every world, there are laws.
Just as water flows from high places to low ones, shared laws exist everywhere. And yet, alongside them, there will always be things that feel utterly alien.
Sex Battle commencing.
Pure white letters carved themselves into empty air.
📍 Victory Condition: Make the opponent climax 3 times.
⚡ Special Condition I: 2-on-1. Penalty reduced by 50%.
⚡ Special Condition II: Insertive intercourse already underway. No special rules set. Continuing as-is.
⚡ Special Condition III: No wager.
Like that one game where you catch monsters and make them fight for you—was this the eyes-meet-and-battle kind of deal?
1. No physical, magical, or mental attacks of any kind are permitted against an opponent—only the delivery of sexual pleasure.
2. Violating Rule 1 will incur a penalty.
3. Contraception is not recommended.
Of everything that had happened since I arrived in this other world, this might have been the most bewildering yet.
Slap! Squelch! Slap! Schlick!
A springy pair of hips bounced and jolted against my lower belly.
"Nnghhaaah…! Ah, nooo…! Keep going there—ngh…! It's been so long…!"
"You fucking dog-elf bitches! Shit!"
"Nyeeh~! I'm a dog-elf bitchhh~! Fuck me like a dog, pleaseee~!"
To think I was giving my virginity away to a couple of random elf whores rolling around on the ground.
Was it the rage boiling up from my chest? Even I didn't feel like myself. Maybe a darker side of me that I'd suppressed my whole life—one I never even knew existed—had finally opened its eyes.
The merciless pistoning went on without pause.

White letters flickered and sparkled before my eyes, but I didn't care.
These fucking bitches. These fucking dog-shit bitches!
"Where the hell do you think you're going?!"
I kept hold of the arms I'd pinned from behind and drove into her from the rear. She was already soaked through; the sound of flesh striking flesh had long since become a wet, sloppy splashing.
Slap! Slap!
"But…! But…! Stop! Ahghh!! It's getting weird! Nooo! Nooo!"
Fwoooosh—!
Another tide of fluid gushed straight down onto the floor.
Target A Climax Count: 2 : 0
"Heugh… nn…! Stop… I'm sorryyy…"
"You fucking bitch…. You two started this. Take responsibility till the end. Trying to finish alone again, huh?"
One of the elves who had leveled a dagger at me was already sprawled unconscious on the floor, and the second collapsed right on top of her with a limp thud.

Gulp.
Two asses stacked one atop the other. Love juices spilling out between them. Bare breasts on full display. My cock stirred back to life all over again.
"Don't just come by yourselves. Let me finish too."
Effects of Ejaculation Delay F and Sustained Erection F have activated.
Like I give a damn!
I pried open the legs of the first one who'd blacked out and flipped her around, leaving the two elf girls looking as if they'd been mid-passionate lesbian sex. That was nice in its own way.
Both of them were still dripping. Maybe they never got near men—their long-grown blonde pubic hair was soaked through.
Smack! Smack!
I slapped my fully hard cock down against that patch of long hair. That had to be her clit, right? After a while of striking it, I could see the swollen little nub bouncing up and down with every hit.
"Ghk! Ah!"
Even just looking, I could tell. A short convulsion hit her—pain and pleasure flooding in together—and she snapped her eyes wide, gasping for breath all over again.
"Please… stop… hyiiiik!"
It was different from before. Her thoroughly loosened walls had melted into something thick and yielding, taking my other half in without the slightest resistance.
"M-my consciousness is…! Flying away again. Nngh. I-I'm dying…! Hnghhh…!"
Ejaculation Delay — ACTIVE!
Ejaculation Delay — ACTIVE!
I shoved deeper. Deeper. With everything I had. At the tip of my glans I felt something like a tiny pair of lips.
"Ahh! Ahh❤ A womb kiss… that's dangerooous! I'm coming agaaain!"
Fwoooosh—!
A tangy spray of squirt cascaded down over her upper body.

Target B has been defeated.
A beast-like growl tore its way up out of my throat.
"Let me come already, damn it!"
Pop!
I sat back hard, the connection coming free, and a cute little bottle-uncorking sound came from down there.
"Hnn… then…. I'll do the… finishing cleanup for youuu…"
The elf who'd blacked out first rolled over, and the two of them arranged themselves into a sixty-nine. She started sucking my cock in earnest.
Suuuck. Hap.
The moment her soft, bright-red lips touched the head, I was sucked halfway in at once.
Schluurp. Schlup.
Someone once said the vagina is like a sedan cruising a well-paved road, anal is a four-wheeler tearing through off-road, and oral is a sports car screaming along at insane speed. If you know how to drive, they said, nothing else can match that pleasure and fun.
They were right.
When she took me in, she sucked with exquisite force; when she pulled back, the hot breath spilling over her soft lips registered with perfect clarity against a glans already hypersensitive and wet. After a few more strokes of that piston, her tongue began to brush lightly against the frenulum behind the head, hunting for the sweet spot all over again.
"Eheh…. Feels good, righht…?"
With her mouth still stuffed full of cock, she kept rubbing her tongue over the frenulum and looked up at me as she spoke.
Effect of Sadism F triggers Dominion F.
I grabbed her head, and she rocked her neck in perfect time with the rhythm of my hips.
"Nngh!"
The urge to come raced from the base of my spine all the way to the tip of my cock. I started pistoning again. Drool ran down her slender jawline and dripped in soft little pat-pats onto the stone-paved ground, and with it the sounds grew even more obscene.
Schluurp. Schlup. Glurrp…. Chaaap…. Schlup.
"Hff…. Heh…. Hff…. Heh…. Haah…. Haah…."
How many times had we repeated it? Grunting moans started slipping from my own mouth. The steady, rhythmic bob of her head; the irregular, wriggling torment of her tongue against the glans. Every nerve in my body seemed to have crowded down between my legs, begging for more stimulation. My sense of time flew apart. My head began to go pure white. I wanted this moment to last forever.
"Heh. Heheh… Riaaa. I'll do you toooo."
The elf on the bottom of the sixty-nine—handling the six—started licking Ria's clit and working fingers into her.
"U-ugp!"
Maybe it was the other elf's caress. Ria's body went suddenly slack, and my cock drove all the way into her throat.
"Ghk! Ghk!"
I couldn't hold it anymore!
I seized Ria's head and started thrusting my hips. Even through the pain she kept sucking, working her tongue for all she was worth.
"Nn… ngh—I'm coming!"
"Mmph! Nghuk! Ehk!"
"You want it in your mouth? Fine!"
Throb! Throoob—!
The climax that had been gathering surged through my perineum and burst free. A massive load of semen erupted inside her mouth.

"Uuump! Fweeh…."
She exhaled a breath so hot you could almost see the steam.

"Aaahn…. So hot…. Haa…. This is real… semen…? It's hot…? Haa…."

With hazy eyes, Ria scooped the semen running down her chin with her fingers, licked it up, and savored it.
"Hnn… so thick… and so much…. Gulp."
Then she swallowed every last drop in a single gulp.
"Fweh…."
Ria opened her mouth wide, showing me it was empty, as if for display.
"Hehehe…. I… ate it all up…."
Was I supposed to praise her?
I carefully stroked Ria's head. She nuzzled her face into my hand like it felt good—and then, still looking content, flopped over and fell asleep.

The nameless elf underneath was already snoring, too—who knew when she'd fallen asleep.

Sex Battler Skill: Training F
Was this some kind of game?
It had been a night full of things I couldn't begin to understand.
The thin, translucent membrane that had been wrapping around us looked a lot weaker now. When I gave it a light push with a finger, it tore as easily as thin plastic wrap.
Leaving the two of them lying there half-naked with their breasts and lower halves completely exposed felt a little wrong…. I hurried into my clothes, hoisted both of them up, and headed for the stables.
Fortunately, it was already late at night—there didn't seem to be anyone around to see us.
"…! He's still just a short-lived race! Ria! Get a hold of yourself!"
"Uuung…. But still…. I like it…. And Mina likes it too…."
Morning sunlight poured down through the broken roof. Outside the stable, what I heard wasn't birds—it was those two elves from last night, chirping and bickering.
"Hmph! Do whatever you want! Stupid Ria!"
"Stupid…? Don't call me… stupid…!"
If I went out there, it'd only get more complicated. Better to sleep a little longer. I curled up as far from the sunlight as I could and tried to drift off again—
"Hey! I know you're awake, human! Get out here!"
Ah, shit.
Maybe if I just pretend—
"I know you're up, so come out while I'm still asking nicely."
Creeeak.
I pushed open the old door—little more than boards slapped together—and stepped out. Mina and Ria were staring at me, looking completely different from yesterday.
I'd written them off as a pair of deranged elf rapists, but seeing them in the light of day… elves really were elves. Sunlight shattered and glittered through her slender strands of blonde hair, and under long lashes her two green eyes were full of life.
"So, uh…. About yesterday…. I mean…."
I scratched the back of my head awkwardly as I spoke, and Mina snapped at me, furious.
"Nothing happened, got it? Huh?"
"R-right, we can go with that, then?"
Honestly, I could only call last night pure luck. The timing of my awakening. The fact that the skill I'd gotten was this incomprehensible thing called a Sex Battle. Even if those two slit my throat and vanished right now, what exactly could I do about it?
This was a world of the strong eating the weak. Sex Battle? I didn't even know how to use the damn thing. I had no interest in staking my life on something I didn't understand.
"I don't wanna!"
Ria shook her head hard, making her refusal crystal clear.
"Don't wanna! Don't wanna! Don't wanna! I wanna stay with the human more…!"
"Ria!"
Watching the two elves keep at each other's throats, a sudden hunger hit me. To be fair, it was just about time to eat.
"Uh…. This seems like it's going to take a while—could we maybe eat first?"
The look Mina gave me was sharp enough to cut.
