Wow your sis is quiet mean... it's a natural thing, everyone is doing it.
uhhh.... it's still awkward to catch someone doing it. by any cultural or modern day standards

It's quiet often that kids catch their parents having sex, I guess sex>>masturbation. It is awkward but nothing to fuss over.
my older sister catch me masturbating when I was child and since then it had been awkward and we don't talk to each other #－.－)
