"Jason..."
You open your eyes as you look around. Yup. You're still a stallion.
"Jason, please look at me." You look to your left to see Jessie, tears welling in her eyes. "I'm so sorry..." she whinnied.
You clop over to her, until you are face to face with the mare.
"That is you, isn't it, Jessica?" You neighed softly. The mare nodded her head.
"I didn't want this for you. When I changed, my thoughts were only on you. I love you so much, and although you're a stud..." she sighed. "I want to be your one and only mate. You're the only one I feel a connection to in this place."
You stared at her sadly, as she looks down. She'd been turned into a mare against her will, and she can't even have you as her mate! You couldn't help but feel mad. She moved around her stall, letting you see a full view of her teats. Your cock got hard again.
"Jessica, I still love you." You say to the distraught mare. "I'll find a way to make you my only mate...I hope." You nuzzled her snout. "I want you to be my only mare." Your human instincts were winning now; you only wanted her now, no longer wanting every mare in the stables. "I love you so much, Jessica."
You actually slept peacefully, happy to know that neither of you lost your human minds, and that neither of you wanted to lose the love you had for each other.
The next morning, the attendant brought you out of your stall. "Alright then, stud. Pick your next mare to breed." You shook your head as you moved to Jessica's stall, who began to cry, knowing you kept your promise. "W-what is this? Pick a different mare!" You nuzzled Jessica. "YOU IDIOT STALLION! I'm not keeping you here so you can practice monogamy! FUCK THE OTHER MARES!" You got behind Jessica and got ready to mount her. "THAT'S IT!" The attendant pulled out a revolver. "If you're not going to fulfill my fetish. I'll just kill you!" Fetish? "Yeah, that's right! The zoo doesn't even need horses! I just wanted to turn humans into horses to fulfill my sick needs! Look at the rest of these braindead horses! They were all human, and they all submitted to their changes! They're mindless beings!" You notice all the other horses, Harry included, glared at her angrily. None of them had lost sentience. "So now I'm going to kill you, you worthless stallion! I'll feel no remorse for killing you, as my pleasure matters more than any human life! GYAHAHAHAH-" The insane attendant was cut off when the rest of the horses ran out of their stalls, out into the wilds, trampling her to death. That left you and Jessica. "We should follow the other horses." You said as the two of you trotted off together, the stable becoming a thing of the past.
