Fuck... I love my cousin. (TRUE)

I was 14, almost 15... it was arround Christmas when my cousin Cierra started talking about her brother , Levi, coming down to spend a week in Arizona with them, considering that he lived with his dad in California. And I'd say about a week later he was there, sitting on the couch, two feet away from me... And I couldn't help but notice how much that he has grown up, he's 16, he's really cute... I can't help but stare... Just looking at him gave me butterflies, and made me smile. I honestly didn't realize that I had grown to like him in that short time, and we didn't even talk, I just felt it.... He's my cousin.
Is it wrong that I fell for my cousin...?
