She was eighteen and aching for it, the kind of raw, filthy need that made her sneak out to the stables after midnight with nothing but a thin nightshirt clinging to her tits and her bare cunt already slick. The old mare's stall was empty tonight. Only the new pony stood there, big, dark, and restless, his cock already half out of its sheath like he knew why she was here.
I dropped to my knees in the straw without a word. The smell of horse and hay and my own wet pussy filled the air. My hand shook when I reached under him, fingers wrapping around that thick, veined shaft. It was hot, heavy, and still growing. "Fuck, look at you," I muttered, voice low and dirty. "Bigger than any guy I've fucked."
I stroked him slow at first, then faster, feeling him swell until the head flared wide and shiny. Precum leaked over my knuckles. My mouth watered. I leaned in and licked a long stripe up the underside, tasting salt and musk. The pony stamped once but didn't pull away. Good boy.
I stood, yanked the nightshirt over my head, and climbed onto the mounting block. Ass up, knees spread wide on the edge, I reached back and spread my pussy lips so he could see the pink. "Come on, stud. First time for both of us. Don't be gentle."
He needed no more invitation. Hooves shifted. The heavy head of that cock bumped against my thigh, then slid up between my ass cheeks. I reached back, grabbed him, and lined him up. The blunt tip pressed against my hole, too big, stretching me already. I pushed back anyway.
It burned going in. Thick, relentless, splitting me open inch by inch. I gasped, forehead pressed to the wood, cunt clenching around the invasion. "Oh shit, oh fuck, that's it. Stretch my little hole." He thrust once, hard, and sank deeper. My knees nearly buckled. The stretch was obscene, my pussy lips gripping him tight, juices running down my thighs.
He started fucking then, short, powerful strokes that rocked me forward. Every thrust punched the air out of my lungs. I reached between my legs and rubbed my clit in fast circles, moaning like a whore while the pony used me. The wet slap of his balls against me, the squelch of my cunt taking that massive cock, it was filthy and perfect.
I came hard the first time, pussy spasming, squirting around him. He didn't stop. Kept pounding, driving deeper until I felt the flare of his head battering my cervix. Second orgasm hit faster, legs shaking, voice cracking on a scream. "Breed me, you big bastard. Fill this cunt."
He whinnied low and shoved in to the hilt. Hot, thick jets flooded me, so much cum it overflowed instantly, pouring out around his cock and down my legs in heavy ropes. I stayed locked on him, milking every pulse, until he finally softened and slipped free with a wet sound.
I dropped to the straw, ass up, watching his load leak out of my wrecked hole. My fingers scooped some up and I licked them clean, tasting us both. The pony watched, cock already twitching again.
Round two started with me on my back on the block, legs spread wide, letting him mount properly. This time I guided him in myself, moaning when he sank home again. "Harder. Wreck me."
He did. By the time the sun started creeping over the horizon I was a shaking, cum-drunk mess, cunt gaping and dripping, thighs sticky, throat raw from screaming. The pony stood over me, satisfied, while I fingered myself one last lazy time, pushing his load deeper.
I limped back to the house at dawn with horse cum still running down my legs, already planning the next night. My first pony fuck had turned me into a filthy, addicted slut, and I wasn't stopping there.
