Improvements

You make changes to the four girls. You add four inches of length to her hair and make it 15% thicker. The one playing with her boobs have them grow a full cup size. The one showing off her ass has her ass grow another two inches in girth, causing her panties to recede into her butt crack, and the one with long legs gets more flexible. You have her think she's always been flexible, and she does the splits on the dance floor before reaching a leg up and pulling it straight up into the air.

As the girls dance, each one's desire to act on her new fetish is growing stronger and stronger. You notice them glancing around the night club and the dance floor. They are all getting lots of positive attention from the men and looks of disapproval from the women.
