Dmitri reared up, whinnying, as he felt his cock and balls retreat into his body. His internal organs rearranged, and a new opening formed just below his tail. Dmitri hung her head low, knowing she was no longer a he.
"Perfect," the breeder said, admiring her. "Just perfect! The finest mare I have ever seen! You can be bred right now, and then I will return you to your herd. They are being bred as I speak. And now, it is your turn."
As though on command, one of the magnificent stallions thundered towards Dmitri. Dmitri didn't even have time to take a single step before the stallion's enormous cock, larger than the one Dmitri had just lost, was plunging into her new hole. To Dimitri's disgust, she...loved it. It was crazy how much pleasure she could feel. And when the next stallion took his turn, Dmitri loved that as well. By the end of it, Dmitri was panting, overwhelmed by orgasms, seed dripping from her pussy.
The breeder seemed pleased and led Dmitri back to the stable with the others. Her stall was between Yevgeney and Ellany, who both had horse semen dripping down their legs as well. An awkward silence fell.
"At least we will finally be giving your parents grandchildren, Dmitri," Ellany said eventually. The five mares laughed. With the mood lightened, Dmitri turned to the plan maker.
"Yevgeney. What now?" she asked.
