"I want to see your world," you replied as Lindsey looked at you surprised for a moment. "What? If I'm going to be a talking horse and I may not be able to turn back easily I might as well be somewhere I wouldn't be seen as a freak, right?"
"Fair enough," Lindsey said with a sigh. "I'll take the memory re-write. I wanted to be a horse, I guess it would feel weird to be one permanently if I remembered being a human."
"Very good," Ms. Tomlin said with a smile as her eyes glowed with strange energy. She looked into Lindsey's eyes first and her eyes glowed brightly before they faded. "There, what do you remember Lindsey?"
"I'm an operative of the Herd sent to bring more humans into the fold," Lindsey said. "I was granted this gift by my Herd mate who I will help to bring more stallions home. My first mate is a former human who will be returning to our home to be the first to breed others."
She turned back and looked at you with a smile. It took you a moment to realize that there was a scent coming from her backside as she raised her tail to reveal her winking slit. You felt your massive shaft slipping out of its sheath, whatever magic had been used on her made her crave sex, and you were having a hard time saying no.
"Go ahead, it'll be good practice for when you get to your new home," Ms. Tomlin said. "And don't worry about your family, my power is greater than you can imagine. Only those who become like us will remember you, so go ahead, mount the mare, you know you want to."
You smelled Lindsey's heat and you had to admit it was hard to resist the urge.
