"Don't worry," said Amy "I poured some of the human vial into all the cups first." she smiled
Mary sighed with relief, then stiffened. "Wait...First?" she asked
"Well," she paused, thinking back "Violet really likes wolves and stuff, so I gave her the werewolf one..."
Violet looked down to see dark claws on her fingers, and dark blonde fur spreading across her arm.
"Whoa..." she said, a little mesmerized.
"Gwen is really into mythology and stuff, so I found on that shelf. I think it was...Gargoyle." she remembered
"I feel really tingly..." said Gwen, a confused look on her face as her skin seemed to be turning purple.
"Abby is really shy, so I just gave her some more of the growth vial..." Amy continued
Abby looked a little unsure as her clothe's were tightening, her shoes beginning to tear.
"Wait," said Mary "What do you mean you gave her more of the growth vial?"
"Well, I gave some to every body." she smiled "Especially me and Abby..."
Amy seemed to shoot upward as her skirt ripped open, revealing thickening thighs that were covering themselves in silky white fur. Mary looked down to see that her new legs ended in large black hooves.
Amy was giggling as a blonde tail shot out of her rear. She jumped around on her powerful new legs.
"This is gonna be so fun!" she yelled as the white fur began to cover the rest of her body.
