Send a concubine to your brother's room and create a drama that she was screwing him while she was out. Try that spend some money on other women to break it up......somethings gotta give.....or you can go screw her and tell your bro she's still sleeping with you when he was not around and ya....remember if you let this thing happen you'll regret and its going to come back to aunt you...............if your story is true in the first place.
