The herd of naked mares anxiously paced the floor as they waited for Stable Master Derek Kage. For weeks, they were assessed for submission, flexibility and how well their mare-holes could accommodate the endless supply of massive stallion cocks and the buckets of cum they were able to produce. But tonight was going to be the first time they were put to work—strapped into the Breeding Wall at The Stud Farm and used by every horse-hung stallion until they were satisfied. Their time had come. One by one, Stable Master Derek took hold of their reins and led them to secured pens. He began with Latin mare Rogelio, securing him hairy chest down, ass up. His ankles were tightly secured to the ground, spreading his bubble ass wide, giving full access to his fur-covered hole and showcasing his stiff, uncut cock hanging between his legs. Twink mare Kyle Brooks was next. His legs were secured high with his ass hanging out of the wall at the perfect height for a stallion to walk up and easily slide his cock into. Finally, inked up twunk, mare Kyle Harper was locked in place. All three mares shook with anticipation, excited that they were finally going to be used as they had been trained for and nervous at the idea of what their mare-holes would look like at the end of the evening.The waiting stallions’ cocks began to harden as the hall filled with the scent of mare pheromones. They knew that on the other side of the door were exposed holes waiting to be fucked for hours and filled with their loads, impregnating as many as they could.Once stallion Donovan Cox walked into the room, his eight-inch prick led him directly to mare Rogelio’s hole, begging to be fucked. Stable Master Derek lubed up his raw member and helped him slide into the hungry opening. Mare Kyle Brooks became cross-eyed, and his mouth gaped open when horse-hung stallion Justin Maxwell lined his nine-inch cock up to his mare-cunt, sunk it in completely and began to use him to service his stallion-hood. Stallion Alfonso Osnaya grabbed mare Kyle Harper's thighs tight and broke the hole open with his eight-inch uncut meat.The playroom was filled with the sounds of stallions claiming mares and mares using their holes to gratify stallions. It was music to Stable Master Derek’s ears. His own erection swelled painfully in his jeans while watching mare Rogelio’s dark-haired cunt get coated in potent cum. Stallion Donovan wiped his cock through his cum that was captured by the dark hair that surrounded the mare’s asshole and rammed back inside to finish spilling his seed. The Stable Master quickly guided the stallion over to fuck and breed mare Kyle Harper with his cum-covered dick.Stallion Alfonso took hold of mare Kyle Brooks’ ankle restraints and fucked his mare-twat hard. He pulled out and shot two jets of stallion cum on the bottom’s hairy nuts and then re-entered the tight hole, coating his mare-guts with the rest of his load. The Stable Master removed stallion Donovan’s cock from mare Kyle Harper and had him tend to mare Kyle Brooks' now used and cum-dripping hole. The stallion dropped to his knees and took the mare’s cock into his mouth and fingered his spent, gaped mare-hole.Finally, Stable Master Derek needed to feel mare Rogelio’s sperm-filled hole caress his horse cock. He easily slid in and pumped the mare’s beefy ass. The Stable Master grabbed the caramel cheeks and long-dicked the mare-slut while Rogelio pulled and twisted his hairy nipples behind the wall. The previously bred mare begged for another load as the Stable Master covered his ass with a man-sack full of perfectly brewed stallion cum.Four spent stallions happily left the stable, drained and satisfied, as the three cum-filled mares patiently waited for the next round of stallions to arrive. How many cocks would they service in the next round, and how many loads would be planted inside of them?
