"No! You did this! You did this to me!" the woman yells.
You stand and smirk, as if to claim credit. You kick the potion vial to taunt her, but in so doing, you nearly topple over. The wide hips and angle of your legs will require more time to get used to. You realize in a start that you may never have the time to get used to it if you don't stay a human very long.
And as you think of that, the woman grapples at her feet and yells, helpless, as her toes start to shift and merge. Your heart races as you realize her feet are becoming hooves. Her human form is fading faster than yours! Your instinct is to comfort her as she howls, but you force yourself to stand by and watch. You did this to her because you wanted revenge. You had better make it feel like revenge.
The woman shrieks as her toes are lost to the hooves, and her feet begin extending. Her legs shuffle and shift, bending and lengthening and shortening until she has legs in the shape of a pig, complete with pink flesh and a covering of thin hair. She stares in horror and you refuse to give her any comfort. She scratches at her legs, yelling and furious, but she cannot take them off and she cannot change them back. She stands up and walks in front of the mirror. She looks comical, and you laugh. She is a little shorter, and you imagine those legs will continue to shrink throughout the transformation. Her enormous, round posterior looks completely misplaced atop those hind piggy legs.
You poke her ass, as if to suggest that she will lose her most prized body part next, and the woman clutches it with both hands. "I've worked so hard for this! You've ruined everything!"
Her sorrow is hard to take seriously. She said just minutes ago that her ass was worth more to her than your life. You wonder how you can make her even more miserable. You risk kicking her in a hoof, and she clops away as you teeter and try to keep your balance. You come to a rest by the hidden medicine cabinet, and out of curiosity, you open it up. Is there anything in here you could use?
Some of them aren't even marked, and you consider just tossing them at her to see what will happen. Some of them look like they might be fun, especially if you only have a few moments of humanity left.
