I never meant to end up on my knees in that barn, but once the big black stallion caught my scent I stopped thinking straight. My name’s Lena and I’m twenty-three, built like a farm girl with thick thighs and heavy tits that bounce when I run. I’d been working at the ranch for two months, mucking stalls and brushing the horses, pretending the heat between my legs every time I walked past the studs was just sweat.
That afternoon the air was thick and the stallion named Thunder was pacing. His cock was already half out, dark and veiny, swinging heavy under his belly. I should’ve left. Instead I stripped off my shorts and climbed onto the hay bale right in front of his stall door. My pussy was dripping before I even touched myself.
“Come on, boy,” I whispered, spreading my legs wide so he could smell me. “You want this cunt?”
Thunder snorted and stepped closer. His flared head nudged my thigh, hot and slick. I reached down and wrapped both hands around that thick shaft, feeling it pulse and grow. It was too big for any normal fuck, but my body didn’t care. I leaned forward and licked the head, tasting the salty pre-cum that leaked in thick strings. Then I turned around, braced my hands on the bale, and pushed my ass back.
He mounted fast. Hooves slammed down on either side of me. That massive cock rammed between my legs, sliding along my soaked slit before the tip caught and shoved inside. The stretch burned. I screamed into the hay as inch after inch forced its way into my cunt. My belly bulged. I could feel every vein dragging against my walls. Thunder started thrusting, short brutal strokes that lifted me off the bale with each slam.
My tits swung and slapped together. Juices ran down my thighs in shiny streaks. Every time he pulled back I felt my pussy lips grip him, trying to keep that monster inside. When he drove forward again my clit dragged along the underside of his shaft and I came hard, shaking and squirting around the invading cock.
He didn’t stop. Stallions don’t. He kept pounding until his balls drew up and I felt the first hot flood of cum explode deep in my guts. It overflowed instantly, pouring out around his shaft and soaking the hay. I reached back and rubbed my swollen clit through another orgasm while he filled me.

When he finally pulled out, a river of thick white cum gushed from my wrecked hole. I dropped to my knees, scooped some into my mouth, and swallowed while Thunder’s cock still twitched above me, dripping the last of his load onto my back.
I stayed there panting, cunt gaping and used, already wondering how soon I could get him to mount me again. The ranch had three more stallions. I planned to ride every single one before the summer ended.
