My little sister's birthday is coming up, I want to do something

you are saying that she is 9/10?

>>35995017
take her to a cat store

Take her to an amusement park or an aquarium or something. Kids love those, and she'll be happy you took her. Make it a surprise, but ask her which one she'd rather go to on her birthday.

do something from the heart anon
keep a good relationship with your younger sibling
I waited too long and my little brother is 18 now

Kinda hard to help without knowing what kind of person your sister is.

Take her to Chuckee Cheese. Going there with just my parents pretty fun back when I was a kid. I spent the whole day playing Metal Slug and Virtua Fighter

Take her to a room alone from everyone else and explain to her how all sex is disgusting and that she must remain pure forever if she ever wants to remain happy.

Amusement park definetly. Don't push her onto any rides but walk onto all the rides with her. It's expensive as hell though for food so if you ain't going to Six flags bring her candy in your back pocket to fill her up first and foremost.
