You are such a little foot fetish freak

You know, ever since mom and dad got married, I've seen that you've been looking at my feet.

And I'm your sister, so what if it's not blood related?

That doesn't mean that it's okay.

I mean, you can like feet and all. That's a little weird, but I'm your step-sister.

Seriously, we're related. We share last names now.
