Jinwoo was a fucking loser.
At least, that's what the other tamers at the academy called him. No contract. No beast. No power. Just a scrawny dickhead with cum-filled balls and a "Taming License" he barely earned by jacking off during beast lectures.
While everyone else was riding slime bitches and banging low-level catgirls for EXP, Jinwoo was stuck mopping cum off the duel arena floor.
"Still a virgin, Jinwoo?"
A tamer girl giggled, straddling her goblin bitch who moaned with a tongue out, green tits bouncing as she got fucked mid-duel.
"Maybe you can tame a fleshlight next, loser."
He clenched his teeth, cock twitching in his pants, hard from watching others bang their beasts like champions. But his shame quickly turned into confusion when something in his chest burned—
No, twisted, like a cock ready to bust inside a monster womb.

His brain flashed white. His balls felt like they were gonna erupt. And in front of him, a wild Slime Girl emerged from a broken summoning circle—blue, jiggly, and leaking aphrodisiac goo from her dripping core.
Her name appeared in his new system overlay:
> Name: Slippa
Rarity: Common
Level: 3
Status: In Heat
"Cuuuummm... need cock... want dick so baaad..."
She moaned with a voice like slurped honey, crawling toward Jinwoo with jello-tits and a pussy slit that opened in her gooey core like a wet mouth.
"Wait, is this real—?"
He didn't even get to finish before she latched onto his crotch, melting through his pants and swallowing his cock whole.
"F-FUCK!"
Her slime pussy wrapped around him tight, suckling like a vacuum, jiggling with every pump. Her transparent tits jiggled with lewd slaps, and her eyes turned heart-shaped as he bottomed out in her dripping fuckhole.
> [Beast detected in HEAT STATE]
[To tame: Fill her core womb with cum.]
[Warning: Do NOT pull out.]
Jinwoo grabbed her gooey waist and started thrusting like a beast.
All the rage, the humiliation, the blue-balled days of virgin agony—he poured it into each deep stroke.
"FUCK—TAKE IT! SLUTTY SLIME BITCH!"
Slippa moaned, her body going translucent as her womb-core pulsed pink and horny.
She was melting from pleasure, her inner walls wriggling like she was already addicted to cock.
Her voice turned into sloppy moans.
"Ahhh—ahhhn—tame meee—breed meeee—fill my SLIME PUSSYYY!!"
Jinwoo felt it. That pressure. His nuts clenched. His vision blurred.
And then—he BUSTED.
"TAKE MY FUCKING CUM—BITCH!!"
> [CUMMING…]

[Beast Slippa has been successfully tamed!]
She is now bound to your cock.
[New Title Gained: Virgin Breeder]
Slippa squealed as thick white cream blasted into her womb-core, bubbling inside her like heated milk. Her goo turned white and pink from the overload of cum, her belly swelling slightly as she orgasmed violently.
"Gyaaahhh~!! I'm—TAMED! I'm a d-dirty SLUT PET now!!"
---
Jinwoo collapsed onto the floor, drenched in sweat, cock still twitching inside the breeding-drunk slime girl.
He looked at the system interface floating before his eyes.

Jinwoo grinned, his cock still throbbing inside the gooey womb.
All those years of being a loser?
Fuck that.
If the world only respected beast-tamers who could dominate monster girls, then he'd become the most cock-hungry breeder bastard they'd ever see.
"Next up… I want a big-titted orc girl in heat."
Slippa moaned under him, licking his shaft inside her own goo.
"Master… let's go find her… I wanna see you breed a whole harem~."
