Wish my muslim colleague becomes my sister!!

So there's a muslim colleague at my workplace we both are gossip partners and we gossip about all the things going on in the company and we are pretty much good friends, so this happened a few days ago when we were having gossip as always while speaking she called me "Bhai" and continued the gossip, the moment I heard that word from her I got an instant horny feeling wish that it was true!!!! She's hot and beautiful at the same time and the thought of having !ncest relationship with her makes me go crazy!!!
