Is there a way to limit who sees what you post but they can still follow/msg you?

I have a lil brother who follows my account and I want to post animation/art videos and they wouldn't be appropriate for his age.

I also just don't want him to see any vent arts etc. I do however want to be able to see what videos he sends me. So is there a way to limit his ability to see what I post??

Please and thank you
