Not getting a lot of replies? Might I once more suggest that you've got the cart way out in front of the horse? I think your issue may be that your wife is still "unaware."
See if she is open to the idea, and if she is, change your approach from "try to seduce my wife who doesn't even know if be cool with it," to "my wife and I are looking for her first experience with another man."
It's likely that nobody wants to help you be deceptive to your "unaware wife" as you call her, and it's nobody else's responsibility to tell her what you want. That's on you, and nobody else. It's time to have an adult conversation with your wife.
