Oh no! My mom wants to read my MJ fantasy stories that I have on this journal app on my iPad and I really don't think it's a good idea for her to read them. I can't just talk back to her. What can I do or what should I tell her?!

I have been writing MJ fantasy stories for about 3 or 4 years. I started writing them my senior year in high school or the same year I graduated (whats the differents?). And I have over 20 stories. I was sitting in the back seat of the car and I was working on a story and mom looked back at me and saw me working on it and she (once again) asked me "Valerie, what are you doing there?" And I say "oh nothing" then I quickly closed it out so she wouldn't see. "And she says" no, it was something. I just saw you. What were you typing in? Are you writing a story? An article? A blog?" She kept asking me. And I kept telling her it's nothing and trying to make up and excuse to make her stop questioning me about it. I keep telling her it's nothing. And yet, she wants to read them. And I can't let her read them. Cause most of my stories are about romance and such. And I'm afraid that after she reads them, she might get mad at me make me get rid of them because they may be inappropriate. And I can't get of my stories. I dont wanna. Not after 3 years of writing all those stories. I love my stories and I just can't get rid of them. These stories are stories that I would like you all (fellow mj fans) to read but not mom. I can't just say "no, mama. You can't read my stories" right in her face. That's rude and disrespectful. However, the main reason why she wants to read them is because she coincide ring me to be a famous writer or author. That's the good thing but I still can't let her look at them. What am I suppose to do?!?!?!
