I am a bull and from what a few said dude your wife knows you had her "set up". She might have been drunk but she knows she was fucked by another man - maybe a real man. Do tell her dude! what if she knows already who fucked her and she has been with him even after that one fuck without your knowledge. It's better to let it in the open so she knows she is free to enjoy as much as she can.. It's what you WANT to happen in any case!
