Midnight was minding her own business, grazing idly, when she felt a stallion mount her. Her head shot up in a panic. Midday was being ridden in a scouting mission. The stallion on her was not her mate!
Midnight turned her head to see Boulder, a massive draft horse, on her back. Boulder was far from the kind of mate someone of her pedigree deserved. His owner said he used to pull stumps for farmers, and he was uncouth and probably not even purebred. Panicked, she tried to buck him off, but Boulder was too strong. All she could do was stand there as Boulder blindly thrust, taking a few tries to finally shove his massive cock into Midnight's pussy. Midnight neighed loudly as he entered her; he was much larger than Midday.
Boulder's owner, a young man named Kellin, looked over. He grinned.
"That's right, Boulder," he shouted. "Give that snobby rich person horse the kind of fucking only a farm boy could give!" He laughed, clearly enjoying the sight of his lower class steed making a noble person's horse his bitch. Midnight was so furious, she didn't even orgasm, despite the intensity with which she was being fucked. Eventually, Boulder neighed loudly and came. A seemingly neverending stream of his seed was shot into Midnight. By the time he was done and dismounted, Midnight could feel semen dripping out of her. No doubt she was pregnant again.
Fuming, Midnight decided to finally leave. It broke her heart to leave her mate and foal, but she was done being bred like a broodmare. Boulder's owner finally looked away. Midnight walked over to the fence in the paddock, lifted the latch, and sprinted away. By the time she heard shouts behind her, she was too far gone. The only one who could possibly catch up to her was Midday, and he was otherwise occupied.
Midnight slowed once she felt she was safely out of range. She couldn't delay any more. She had to go to the Eastern Hills to find Anya. So, she set off on the direction of the Eastern Hills. She missed the company of her beloved mate, but as her belly slowly began to grow again, confirming she was pregnant once more, she knew she wouldn't be alone for long.
