Open Question: Why am I turned on by my sister?

[feedcrawler]

I'm 16 and my sister is 18. We often like to "play wrestle". I used to like it just because I like the competition. But for the past 2 years, it's been a little bit more than that. She puts me in moves where she is sitting on my face, with my arms pinned down. I am absolutely helpless, but I don't mind one bit. She hasn't notice that I'm turned on yet. She also puts me in moves like breast smothering, which I am also a sucker for. I also have a big foot fetish, but I didn't think it would apply to my sister. Sometimes we make the wrestling match have some stakes, like the winner gets a foot rub from the loser. So obviously, losing is fantastic for me. She gets me in positions that I enjoy being in, AND I get to rub her feet. She thinks of it as just innocent sibling wrestling, but to me it's much more. Although I love wrestling her so much, I know that I shouldn't be doing it. I don't have any thoughts about having s*x with her, I just want her body parts in my face. Is this really that wrong? That I am submissive to my gorgeous sister?
