TLDR caught my brother with another chick while his gf is none the wiser. They're both 20 year olds but I'd be lying if I said I wouldn't fuck his gf if given the chance and part of me wants to let her know and then she if she's down to revenge fuck and cuck him. I'm not too close to the guy and he pulled an awful fucking stunt the other day which left a bad taste in my mouth. Also if she is down what would be a tell to know she is? Any advice is greatly appreciated.

Yeah i think fuck you and your brother

lol you just want to fuck her and are making excuses in your mind for doing so
might as well just admit that instead of lying to yourself about the reasoning behind what your doing
also there is a huge gap in logic from "telling her my brother is cheating on her" to "hey wanna revenge fuck" you don't even know if she's attracted to you it seems
you're so autistic bro

I hate my brothers and I would gladly cut off my ties of them, but even I would not fuck their girlfriends. Shit is just weird and messy.

Call him out on his shit behaviour. Or don't. That's all you need to do.

To me, it sounds like you have a massive inferiority complex to your brother.

What makes you think his girlfriend is going to let you fuck her anyway?
