Assure her it's not pee
From Create Your Own Story
Deciding it's best to be honest with her you comfort her you hug her from behind and twist her around to face you "no, it's not pee don't worry you didn't have an accident. Remember when I told you how a boy's pee-pee can get happy and shoot something special well girls pee-pees that are called vaginas and some people call them pussy's for slang they can get happy and wet too it's not exactly the same but it ok it just mean you enjoyed what we did too. Did you enjoy it?"
She nods "oh yes it was a lot of fun it felt strange and weird but kinda good"
You kiss her lightly on the forehead "good let's get cleaned up" as you break your embrace you look down and see she has a tuft of pubic hair.
Grace notices you staring at her pubic region specifically the hair down there and blushes "oh yes I've had hair there since I got my boobies" she giggles as she says boobies knowing it to be a dirty word but having fun saying it "is it ok to have hair there." she ask" worried that it might not be ok.
You decide:
tell her pubes are natural (hey hair down there is good if there's grass on the field play ball)
tell her it's gross (you're a firm believer in all woman should be bald from the neck down)
