Ivy was brought to the mating paddock first. The stallion, a massive beast of a horse fittingly named Goliath, looked at her with what could only be described as hunger. He was a draft horse, not the same breed as Ivy or Clover.
"We need more heavy duty work horses," Gunther said to one of the people observing. "Yes, the foals will be mixed breed, but they'll be useful."
Ivy stood in resignation as Goliath sniffed her vagina. She sighed and obediently moved her tail to the side. Goliath lurched forward. His hooves slammed on her back, making her nearly buckle under his weight. He took a few tries to enter her, but when he did, Ivy cried out in pain.
Goliath's cock was so huge! Her pussy felt like it was bursting at the seams trying to contain it! But quickly, she got into it, whinnying as pleasure rippled across her body. Goliath shot his seed into her, then dismounted and moved over to Clover, who had been brought out while Ivy was being bred.
