"I haven't had a first date since we got married. I want to look good for him and make sure he knows my intentions for later in the evening. What do you think?"
On a first date with another man, I want to look good first of all for me and my husband and then for the other man. It's a date, it's not mandatory to have sex with him, maybe he's not the right guy...
You and your wife had role played cuckolding numerous times -- but you never thought things will progress beyond that. Apparently, your wife has had other ideas, and she strongly encouraged you to set up this "date". And even after you had set it up, you doubted she would really go through with it. But there is no question now that she's going to. And it's clear that this is not going to be a "one time" cuckolding.
