Autistic sister [13f] plays with my [20m] ears inappropriately and doens't stop when asked. I unintentionally scratched her when she did it unexpectedly and she hit me. How to put an end to this?

My sister (who is otherwise very well adjusted) gets very stubborn about playing with my ears, and people's ears in general.

She's done it to many people (mostly family members but also her school friends) and mom and dad make a point every time to tell her firmly that she can't do that without permission, and she generally gets angry as a result.

When she was a little younger she would come close to me and while we were doing something together (homework, videogames, good night story) she would start playing with my ears. I definitely don't like and I would tell her this. Like "hey, I've told you I don't like this, you have to ask for permission. And either way, I would have told you 'No' because I don't like it" and she would mostly give me an embarrassed smile and not do it again for a while.

But at some point she'd do it again, and some time later again, and so on. Bizarrely, she would sometimes try to bite my ear or earlobe, luckily with her lips and not her teeth, and that would spark most of the heated discussions about this.

Two days ago she did it again out of nowhere. I was in the couch and she suddenly came from behind me and held my head with her hand and then went right into grabbing my ear and biting it with her lips over her teeth. I reacted almost by reflex and tried to get her off me, and accidentaly hurt her cheek (very lightly to be honest) with my fingernail.

She said "Hey!" and pushed me with both arms on the shoulders. She was going to do it again but I grabbed one of her hands, so she tried to I guess slap my head with the other and I grabbed that one too. Then she yelled at me to get off and when I did she flailed her arms at me and left.

When our parents asked about it and I told her, but she didn't want to talk about it and curled in the corner of her bed without saying anything. LAter I tried to talk to her again and nothing, she also ignored me.

The whole thing was a seriously WTF moment that came literally out of fucking nowhere. Parents were also confused and had to tell them like "remeber how we would sometimes argue with her over touching other people's ears and such?".

I want to clarify that she is well behaved and doesn't have conflicts in school (that we know about at least, I guess). She has friends and acts normally most of the time.

So, WTF? What should I do about this? Is there a way to talk about this with her in a way that has, you know, long term effects and she finally understands that it is inappropriate?

tl;dr: Sister plays with and sometimes lightly bites my ears. We have been having this conflict for literally years. She recently did it again and I was taken by surprise. I accidently scratched her cheek and she pushed me and tried to hit me, and later didn't want to talk about it. What should I do to put an end to this thing once and for all?
