Terra had been convinced by her close friend Gothica to have some experimental transformative tests done to them "as they paid well" and had just arrived at the lab.
She and Gothica were told that they were going to be test subjects for a new and experimental Drug that would transform them into something "beautiful" and "exotic" though there may be some side effects.
Having signed the contract Terra couldn't back out as she really needed the money after recently losing her job and having to work as an online game streamer but it wasn't covering her financial needs.
They said that everything would be taken care of if she went through with their "tests".
She was curious to know what a "Dorse" or a "Queen Stallion" would feel like as she had only seen Porn of it and a few Kinky stories though she figured it couldn't be that bad and they said that it was only a "temporary" thing so there was no room to worry.
