How would you feel about your best friend hooking up with your sister?

And would you hook up with your best friend's sister, regardless of how he feels? For this scenario imagine she is really hot. And totally into you. And you two hit it off like crazy.

i think if you respect your best friend at all, you look at his sister like she's your sister too.

unless he tells you to go for it, but you definitely get his opinion first.

Bros before hos. Always.

Unless you and the sister have known each other for so long that you're practically a couple already.

Isn't it kind of a moot point if you're already hooking up?

This is purely a hypothetical scenario.

I'd feel weird about dating the sister of any of my friends. I've only had one suggest that I date his sister, though.. which I declined, because obnoxious alcoholic chain-smokers are just not my type.

i dated the sister of a close friend/co-worker for a while. i definitely made sure to see if he was cool with it before we went on a date at all. it's only right and respectful.

that being said still a lot of weird moments there. really weird since we had the same name (her brother and i). and even though he said it was cool, he never really was okay with it. you could tell. luckily it only lasted a few months.

depends how much i like or dislike my sister

Aside from the fact that they have nothing in common, I really don't see a problem with it.

I guess it doesn't matter anyway.
