Grouchy Grace and Her Magical Grool (Open)

This story is now open to others who would like to tell tales of girls with magical pussy juices. I moved all the stuff about Grace to her own chapter so that this can be a more generic introduction. The tale of Grouchy Grace is one of mental and physical changes, but feel free to focus on just one or the other if you prefer. Or perhaps the grool in question doesn't control people but bestows some other benefit, like super powers. Maybe your Grace is the Professor X of a group of heroes who have to regularly imbibe her sexual juices in order to maintain their powers. Maybe her cunt is the fountain of youth, capable of slowing or reversing the aging process. Maybe her pussy slime is the only cure for a magical disease and she demands a quest fulfilled before bestowing her vaginal blessings.

I hope to see some wacky ideas from people!
