Banging Friend's Siblings

I'm a little confused on the fact that nobody is asking the question "how close am I to the sibling?"
I mean, sure, I can be best friends with a guy, and end up loving his sister. I don't see why not.

Because most people have the decency to not do shit like that?

don't hate, appreciate.
or else i'll murder your family and use their corpses as a costume when i rob liquor stores and enslave your dog to do human moral work and feed him chocolate as a treat when he completes its tasks of (utter) uselessness....

The first gal I banged was a sibling of my best friend. She is a half-sister though, and he did not grow up with her. Problem? I think not. She is quite a bitch though, so I dropped her ass a long time ago. Damn near ruined my new tattoo mid-coitus.

Speaking of mid-coitus...

Your point?
