mute someone from reading one of my stories?

I have a friend that reads one of my stories and she’s big on keeping things appropriate and stuff like that and she’s kind of a snitch in a way.

But she reads one of my stories that doesn’t have anything bad in it or anything and she really likes it.

But I also want to create something more mature in a way, but I don’t want her to see it and to start going after me for it.

I want to say I don’t care but I really don’t wanna get any shit from her.

Is it possible for me to muting her from reading one of my stories or a story instead of blocking her entirely?
