Me and my brother "flirt" in a way, we aren't blood related though so I guess it's less weird. But we hug each other and hang on each other and shit, but we don't have any sexual intentions, we just love each other a lot. There's a weird unbreakable bond. We're also only a year apart so it's like having a best guy friend who just happens to be related to you lol. (he's also a very cute kid and if we weren't brother and sister I'd probably have a huge crush). I also find that his girlfriends get kind of mad at me sometimes and jealous in a way, which I don't understand.
