Sacrifice
Kala shifts on her hooves wincing to feel the ropes biting in around her hocks. The small centaur secured against a large boulder, her upper body forced painfully over. Restraints holding her arms widespread, the rock rasping against her chest leaving raw welts. Her equine half splashed with patches of white and black, is equally restrained. A spreader bar forcing her hind legs awkwardly apart, a loop of leather forcing her tail high revealing oozing from her swollen vagina. Tears still wet on her cheeks while she remembers.
Her village had a tradition, going back generations. Each spring they offered a sacrifice to their gods, hoping for a rich summer of plenty and to strengthen their race. The first filly in spring to come into her first heat was offered, the males of the village watching closely. Kala had tried to hide it, gone to bath each day in the pond to cover up her scent, all the while desperately hoping someone else would enter their season. But the villagers were keen eyed and keen nosed, letting her attempt to hide herself while waiting patiently. One morning she woke up with her folds burning, dripping a sticky liquid between her legs and winking every time she got a whiff of a male. That's when they came.
She had tried to struggle, to buck and fight, but they were larger, older. Her body dragged out into a field where the alter stood, heavy rings of metal set into ready for her. She'd cried and sobbed, pleaded and whimpered as she was forced down. A bit forcefully shoved between her teeth and the reins used to hold up her tail, each breeze a torment to her overly sensitive folds. She waited for him, a nervous sheen of sweat covering her coat, hearing the stories of what was to come. Her scent hanging in the air, a declaration. She had expected it to be over soon, for him to come out almost immediately, but he didn't. She lay there in the sun miserably, the awkward position of her body making her ache and unable to give herself any relief.
Kala was small for a mare, even among her kind. They weren't hulking beasts with the bodies of drafthorses, they were smaller. Backs coming even with most ponies, the laughing stock of larger breeds of centaurs. Remaining seperate from all of them to farm and trade as they needed too, but sometimes, like now, they tried to improve their breed. To have the next generation be stronger, bigger, and that's why she was tied and bound.
Suddenly the muffled fall of hoofbeats came to her ears, making her jerk sharply straining to look behind her, praying it was someone coming to release her. The prayers went unanswered as a hot rush of air came over her dripping vagina, followed by a broad tongue as she jerked and tried to bolt. The ropes held her firmly in place as a hot equine tongue probed into her virgin body, the stallions nose wrinkled back to suck in the scent. The full grown horse easily twice her size as he explored her, licking and slurping wetly as she started crying in fear. This is what it meant to be sacrificed, mounted and bred by a common horse in the hopes her foal would be larger and stronger.
Her face flushed, trying to ignore what she couldn't change, not even able to see the stallion as he suddenly lifted his head. The thick equine cock dropped from his sheath to dangle under him, as he placed his head on her rump eagerly. Her legs braced instinctively, unable to stop her folds from winking at him as his head rested on her broad rump. It seemed almost like an eternity before a heavy chest landed on her back, forelegs scrabbled against her sides for a grip. The girl gave a sob of protest before she shuddered, a blunt tip bumped and bounced off of her hindquarters leaving sticky trails of precum.
All too soon the stallion found his mark and begain grunting, her cunny started to splay painfully around him until she screamed out. She could feel blunt teeth gripping her whithers a moment before he thrust forward, her vagina split open around him as he shoved a few inches. Kala's body trembling in pain and horror, sobbing to try and block out the grunts and sick wet sounds heard as he shoved inward and ripped her open. The stallions hooves nearly touched the ground as he slammed his hips forward against the tiny filly, driving in and out until her swollen pussy was impaled.
Kala whimpered and cried, her body forced against the rock with each slam of the stallions hips, even worse she felt the hot slippery precum oozing into her. Grunting as the tip battered against her cervix demandingly, the stallion ignored the sobbing under him and mated her like he would one of his own mares. All too soon she felt the tip start to spread out, his thrusts growing shorter and rougher as if he were trying to punch through her cervix. The tiny filly gripped the rock and could only grunt as he succeeded, forcing the cock into her unprotected belly.
The stallion held still for a few moments before his cock lurched and pulsed, spraying a rush of thick semen into her womb. The mare trembled and flushed in shame, feeling the sickening wetness covering her, billions of sperm wriggled into her womb to join with her egg. Her head dropped against her hands barely moving as the stallion jerked his cock free, only hearing the disgusting splash of cum that fell onto the ground under her. Already inside of her one persistant sperm pushed through into her egg, forming new life into her body.
