This month's idea comes from Fishin2244 :
Hanna from “H2grOw” decides to pour the breast growth formula on herself while locked in the closet with Peter. Her breast are at watermelon size and she decides “moar” is better. No one will be bigger than her.
As a bonus, I've included the initial rough sketch sent to the patron.
