My brother keeps slapping my ass, what to do?

Anonymous

Ok so my brother (15M) keep slapping my (19F) butt "for fun".

I've told my parents and they seem to tell me its only for fun and I should let it go. My dad always slaps my mom's ass and she tells him to stop as a joke (even thought she clearly likes it), so maybe he's taking a bad example from that?

He also keeps staring at my breast and I've caught him standing discretly looking down my shirt when I was sitting.

Here's the important part: I've slapped him and he almost seemed not to care/laugh it off. I've also threatened to kick him in the groin but he keeps doing it and laughs, almost like he doesn't believe I'm gonna kick him.

Should I kick him? Any other ideas? I don't want him to slap my ass anymore and he can be such a pervert, I want him to respect women/not get in trouble later on. At the same time I kinda don't want to hurt him, he's normally a very good brother.

Summary: brother keeps slapping my ass, threatened to kick him but not sure I want to hurt him, not sure what to do
