She stood naked in the barn, wrists already cuffed behind her back, while he buckled the thick leather harness around her tits. The straps bit into her skin, squeezing her breasts until the nipples stood out hard and red. He cinched the waist belt tight, then forced the bit between her teeth and fastened the bridle behind her head. Drool leaked from the corners of her mouth instantly.
“Legs apart,” he ordered. She spread them. He shoved a thick, lubed plug up her ass, the long black tail sprouting from the base swinging between her thighs. She grunted around the bit. He clipped reins to the rings on either side of her mouth and gave them a sharp tug.
“Walk.”
She moved, knees high, tits bouncing with every step. The tail brushed the backs of her legs. He led her in circles around the straw-covered floor, making her turn, stop, and back up until her thighs burned. Every time she faltered he cracked the crop across her ass. The sting made her cunt clench.
After twenty minutes he stopped her in front of the breeding bench. It was low, padded, with stirrups. He bent her over it, locked her cuffs to the front bar, and spread her legs wide in the stirrups. Her tail hung down, the plug stretching her hole. He grabbed the tail and yanked it, twisting the plug inside her. She moaned, the sound muffled and animal.
He unzipped and pulled out his cock, already hard and leaking. No warm-up. He lined up and drove straight into her pussy in one thrust. She jerked forward, the bit pulling her head back as the reins stayed taut in his fist. He fucked her hard, hips slapping against her ass, the tail swinging wildly between them. Every stroke shoved the plug deeper. Her cunt was soaked; the wet sounds filled the barn.
He reached under her and pinched both nipples, twisting them while he pounded her. “You’re just a dumb pony now,” he growled.
“Made to be ridden and fucked.” She whinnied around the bit, hips pushing back to meet him. He pulled out, spat on her asshole around the plug, then yanked the plug free and replaced it with his cock. She screamed into the bit as he sank into her ass. He fucked her there until her legs shook, then switched back to her cunt, using both holes until she came hard, cunt pulsing around him.
He didn’t stop. He kept going until he flooded her pussy, cum leaking down her thighs and mixing with the straw. Only then did he pull out, wipe his cock on her tail, and leave her strapped to the bench, holes dripping, ready for the next round.
