Little did Jen know, Susan had no understanding of the limitations of the curse.
“For your transformation, you’ll have all of the following: a straight back, normal legs and feet, a regular dairy cow udder that makes milk and anyone can milk it, double-D breasts with regular nipples, and no bowel movements if you can’t control them. Your pussy and asshole will go to a normal spot on your body, and whatever you end up as will be seen as normal or acceptable by everyone that doesn’t know you were cursed.”
Jen was too shocked to stop Susan. Already, she began to feel the curse course through her body, fighting itself as it tried to make both curses true.
First, a second pair of breasts ballooned out between her G-cup breasts and her urine-filled udder. These breasts reached exactly the size that Susan had said, but they looked comically small directly beneath her comparatively-large original pair.
Next, a second pair of legs began to slowly grow in front of her original pair. As they did so, Jen toppled forward, barely catching herself before she smashed her mammeries into the floor. As she waited for the curse to finish growing this second set of legs, she realized the gap between the upper and lower legs had drastically increased, giving at least 1.5 to 2 feet of “chest” to separate them.
As the second pair finished growing in, Jen stood on all four of her legs. The back pair were still hunched like Kyle’s curse had commanded, but the front legs looked like normal human legs, like Susan’s “cure” had called for. It was as if her butt had been expanded into half of another person, complete with a ribcage and gut of its own. She’d read online about smut somewhat like this, but she’d never found it enticing to search for: a humantaur. Like a centaur, but human parts where it should have been a horse.
Finally, she felt a familiar bulge on her new lower body “stomach,” like what she had felt with her original udder. Where Kyle’s udder had grown in slowly, Susan’s version of an udder was much faster. It quickly surpassed the size of her petite udder, filling more and more space until its teats drooped past the knees of her back legs. The mammary was so large, it was wider than her torso, and it clearly wouldn’t be hard to accidentally kick the thing with her front legs.
Wracking her brain on how something this bad could have happened, she realized it: Susan had said a regular dairy cow udder. Her new mammary looked so oversized on her because it was supposed to be on a bovine several times larger and heavier than she was!
With that, the changes seemed to subside. Her anus and vagina were still rear-mounted and she didn’t grow a second set of them, but her quadrupedal form did make both Susan and Kyle’s curses true enough in their current orientation. She didn’t want to think about what might happen with her bowel movements. Was she never going to poop again? Would not pooping for too long cause health complications?
“Susan, what have you done?”
Susan was still staring in horror. “Oh my god, what happened to you?! I said to make you normal, not get two of everything!”
