He stepped into the barn with his dick already straining against his jeans, the smell of hay, sweat and animal musk hitting him hard. The big black stallion stood in the stall, muscles twitching under glossy hide, tail flicking. Jake had been feeding and brushing the beast for weeks, watching that heavy cock drop lower each time he got close.

Tonight he wasn’t stopping at brushing.
Jake stripped fast, cock springing up thick and leaking. He climbed the stall gate and dropped inside, bare feet in the straw. The stallion snorted and shifted but didn’t pull away when Jake ran a hand down its flank and reached underneath. The sheath was hot and leathery. He gripped and stroked, feeling the massive shaft start to slide out, veined and blunt-headed, already dripping. “Yeah, you like that, big boy,” Jake muttered, voice low and filthy. He dropped to his knees in the straw and opened his mouth, tongue dragging over the flared head, tasting the sharp, salty pre. The stallion stamped but stayed still as Jake sucked what he could, stretching his lips wide around the thick meat, spit running down his chin while his own cock throbbed untouched.
He stood, turned, and braced his hands on the stall wall. Reaching back, he slicked his hole with spit and the stallion’s own pre, working two fingers inside himself quick and rough. The horse’s cock hung heavy behind him, hot against his thigh. Jake lined up, pushing back, feeling the blunt head press against his stretched rim. It took pressure and patience but the head popped in, stretching him wide open. He groaned, forehead against the wood, hole burning and clenching around the invading thickness. Inch by inch he worked himself back, taking more of the stallion’s cock until his belly felt full and his own dick was dripping steadily onto the straw.
The stallion started to thrust, short powerful strokes that rocked Jake forward. Each shove forced more of that massive shaft inside, the medial ring catching on his rim before pushing through. Jake reached down and jerked his cock in time with the thrusts, grunting every time the horse bottomed out deep. Sweat ran down his back. The barn filled with the wet sound of fucking, skin slapping against hide, the stallion’s heavy breathing. Jake came first, shooting hard across the straw, hole spasming tight around the beast’s cock. The stallion kept pounding, then whinnied and unloaded, thick hot jets flooding Jake’s guts until cum leaked out around the shaft and ran down his thighs.
He stayed impaled, panting, until the stallion’s cock softened enough to slip free with a wet rush of seed. Jake dropped to his knees again, scooping some of the mess and licking it off his fingers, tasting the mingled flavors. The stallion nosed at his shoulder. Jake smiled, already feeling his cock twitch again. Round two would come after he caught his breath, and he planned to ride that stallion cock until neither of them could stand.
