I need a little advice.

Yesterday, while my wife and I were driving in to work together (we work at the same place), we were talking about an event I'm attending Saturday with a newly-made female friend who's about our age, also works with us. Wife's staying at home and I'm heading off for pretty much the whole day, basically carpooling and then separating, carpooling back, maybe dinner together while we are out. I have been out with her before and have had folks mistakenly ask if she was my wife, super awkward, but we correct them and move on.

New Girl says she loves what me and my wife have, and I have never thought of her sexually (at least not in a serious sense). She's loud, just about my height, thick, and kind of domineering, compared to my shy, petite, and submissive wife. It's REALLY hard for my wife to make friends, especially female ones, so I'm ecstatic that she hangs out with New Girl as often as she does. My wife says she feels no threat from her whatsoever, and doesn't mind us hanging out alone (we have a few times, no big deal).

Anyway, I was talking about our trip Saturday, and double-checking that Wife was okay with everything. I cited an article I read about opposite gender friends with couples, and how I wouldn't be comfortable with her going off with another man (I know, that's not right, but still). I was trying to give her a way to tell me not to go if she wanted me around the house or was uncomfortable. Instead, she says "if you've gotta do it with New Girl, bring me along." My jaw hits the floor and I'm instantly rock hard.

People, this is a woman who has threatened bodily harm to me if I ever cheated on her; told me that the ONLY reasons she'd ever leave me is if I hit her or sleep around on her. Wife has told me that she thinks licking pussy is gross and she isn't into it at all. I was in absolute shock, and stammered out a pretty nonsensical response.

I ran into New Girl yesterday afternoon, on the way to pick up Wife, and had an awkward conversation, picturing a threeway instead with her and my wife. Or a cuckquean situation where Wife watches me and New Girl go at it, which really got me excited. From really no interest to serious curiosity of what it would be like to fuck her silly with Wife's permission. Or be fucked by her, I get the feeling New Girl would be very dominant with me, and that is a fucking turn-on.

So I don't know, was Wife just playing around? Did I just get a hall pass? Anyone else have this sort of thing happen and it go well?
