Katie starts to think the vial isn't working when she starts to tingle all over. She quickly removes her clothing, and then watches as her body grows. She gains muscle and then shoots up until she's back to her normal height. Her chest expands out to a G cup. And below her pussy lips grow a bit bigger.
"Back to normaaaaa..." Katie started to say when her body shakes with the next wave of transformations. A long bushy tail extends from her back, and then fur races up. Two more pairs of breasts appear on her chest, and she gains pointed ears on the top of her head. Whiskers push out of Katie's top lip, and her nose flattens. Once the changes are done, she's left a catgirl, from the waist up. Her hands have small claws, and her torso is patterned in brown tabby stripes.
"Wow." Tony said, looking at his friend. Katie turns around to look at her new body.
"Huh, I wasn't expecting this."
"That vial says 'Dream Maker'. You want to explain?" Tony asked.
"Well, remember when we were kids, and we got asked what we wanted to be when we grew up? And remember how I always wrote the same thing?"
"Ya you wanted to... holy crap Katie. You wanted to be a cat when you grew up!" Tony exclaimed. Katie nods her head.
"Ya, guess part of me held onto that. But nevermind my transformation, what about you? You wanna try?" Katie asked, picking up the "Dream Maker" vial.
