I know it's not right to spy on my sister while she's taking a shower...

It's not that it's okay, it's awful, damn it, but hey, we understand because you have a stepsister who's gorgeous and has a great body, so we understand why you watch her and record her, especially since you don't send it afterward because that way we can see it, and more than one of us will probably have a good wank to your stepsister, I mean, I'm convinced...
