My cousin who's literally in 7th grade made nsfw art

PLEASE PLEASE someone tell me this was made by some artists cus I'm mad concerned if she made it she should not be making these kind of art. I don't know how to handle this situation?? Cus I've never been close to her much and the parents are hella religious. Also not my girl finding out abt yaoi... Is this my place to talk to her abt it as an older cousin?? She has older sisters. Which I'm also not very close with. She's in 7th grade, she's a child. I am worried about the places she might get into. SHE FREAKING POSTED THIS ON HER FACEBOOK with all the relatives for to see.
