Busty Fennel Chibi

SOMEONE FOR THE LOVE OF GOD TELL ME HOW YOU DRAW BREAST EXPANSION. I feel like an underdog at the beginning of a kung fu movie who needs to be taken under the wing of a ninja master to hone his skills and be a badass by the end of the movie. seriously, halp plz. I am doing SOMETHING wrong here I just..... ugh.

But Busty Fennel needs to be drawn more.....
