Bro code question???? Hooking up with friends sister

[Mr.Rob]

Went to an adult Christmas party last night that my parents took me to. The family throwing the party has two children around the same age as me (20), one a boy and the other a girl. I'm super cool with the dude we've been friends since I was 7 but never on a hangout all the time basis so we don't know each other super well these days. Just spent a lot of time together as kids and have a mutual respect for one another.

His sister on the other hand was chasing me after sharing a couple sentences from when I first arrived to the party (she's wanted to get with me since 2nd grade literally). Not super hard but enough for her to lie about not having a boyfriend to me after telling me originally she was dating someone. lol. I guess she broke up with him after she realized I had some level of sex appeal. Anyway my question is:
What is the bro code for hooking up with friends sisters? I'm an only child so I can't really empathize one way or the other. I guess it would depend on how protective the brother was. I've seen brothers give two shits about some guy/friend railing out his sister and others that get pissed when you look her way.
Do you talk about it with the bro (obviously you wouldn't if you weren't good friends with the bro in the first place)?

Honestly this girl is super unloyal (didn't use the word slut!) in her relationships and just likes to have fun. Perfect material for ONS. I was thinking just invite her over to my house hook up and not tell anyone about it as I think she wouldn't say anything either.

Someone fill me in on the protocol here?
Thanks

Rob

Do it. Don't disappoint her on account of a third party. It's none of his business.

And no, don't clear it in advance with her male relatives... Where are you, Saudi Arabia?

Rob,

I agree with Casanova and Marty, you should do it. If the brother was one of your really close friends that you had known forever and have always hung out with a bunch, then it might be a different story. I think that if I hooked up with any of my really close friends' sisters, I'd probably tell them so they didn't find out some other way and get pissed off at me lying to them and not saying anything. But since that's not the case here, I say go for it. Especially since you only want a ONS, I wouldn't bring him into the situation. The sister really wants it too, and has for a long time, so you shouldn't let the brother stop you two from doing what you want.

Pato I agree with what you write EXCEPT this. By doing that you would be violating the girl's confidence in a very unfair way. A secret is a secret. It's her reputation, not yours, that you need to consider.

It's not about bro code, fellas. This is about "lover code". Do it and keep it quiet, for her sake.

lol.

Thanks for the rapid responses fellows! I was honestly leaning this way the whole time I just wanted to clear it in advance in case there was something I was overlooking. The show must go on!

Marty, looking back at what I said, you're right. I was kind of thinking more so if I got into a relationship with the girl I wouldn't go behind my friend's back about it and lie to him, but yeah you're right. It is very important to keep the secret between just the two of you, no matter what the situation really is. And you really don't want to break her trust in you, as it isn't good for either of you.

It's weird, I feel like everyone in my social group gossips and knows everything about everyone's relationships. Maybe that's just because I'm in high school (and we all know how different high school is), but I feel like I'm one of the very few in my group that would be discrete about hooking up and not tell a bunch of people about it.

Since you said you guys don't talk too often, I'd say do it. As the guys above said, make sure you set that "our little secret" frame.
