Well first I'd wonder where I magically got a sister from....then incest.
I would too. The only sibling I had was an older brother who died a couple years ago. So, if I just magically had a sister, she wouldn't be related by blood and that would mean, obviously, that she wouldn't be off limits. If she was hot and she responded "favorably" when she walked in, I'd totally fuck her. The thing is that when its your sister, blood-related or not, you live with her. If you do fuck, it might cause some weird vibes and make your home life a little awkward.
