Had my first threesome and our unicorn pmo

If you don't care to read about how this situation came to be, skip to the 3rd to last paragraph. Everything goes well leading up, but we trip over the finish line Me [M25] and my wife [F24] have been dating since high school and we have only had sex with eachother. She was in a few lesbian relationships before, and a while back she told me how she kind of regrets never having the chance to, rather specifically, eat a girl out. Flash forward a few months and over a few drinks we discuss with one of our friends [F24] that we are looking for a threesome. She tells us that one of her friends [F23ish], we'll call her Caroline, had been eyeing the both of us when all of us went on a boat trip a while back. We get her number, we hang onto it for a while and don't do anything with it. Flash forward a few more months to last week, and Caroline texts me Friday night about a possible threesome. I add my wife to the text chat and we hash out the details (expectations, boundaries, we do a little sexting), and by early Saturday afternoon she rolls up to our house ready to get fucked. Now in the beginning it's going well. We have a couple of drinks to loosen up and it's off to the races. Of course it's my wife's first time with a girl and my first time in a threesome, so we kind of struggle with trying to fulfill all our fantasies in the first five minutes. But we settle into our rhythm and after a while it seems we got it figured out. Everyone's giving what they want to give and receiving what they want to receive. I won't go into much more detail than that, but we definitely learned a lot about ourselves. One agreement we made before hand is that because both of the ladies are on the pill, we don't need condoms. The plan is for me to finish in my wife, our new friend to eat it out of her, and then kiss it back into my wife's mouth. Just as a hot reminder that my wife is in charge, not her. But what happens is I'm doing missionary with Caroline, my wife is kissing me and sitting on her face. I realize I'm about to finish and the easiest thing is to pull out and take a quick break. But Caroline reaches down, gives me a few quick strokes and I finish all over her stomach. My wife licks it up and feeds it back to her. Now it's not really that big a deal to me, but with how big consent is with sex, I was more concerned with the fact she broke our agreement. But she was a nice lady so I let it slide. Our aftercare routine pretty chill. We put on pajamas and I start a French onion soup on the stove (I caramelize onions in bulk so it didn't take long) and we watch Christian Slater in Pump Up The Volume. At the end of the night she goes home. No more than 2 hours later she starts texting me (not my me and my wife, just me) about how her door "and legs" are always open. I text back telling her how my wife and I enjoyed it and we think she's a wonderful woman. She texts back saying that my wife was okay and she'd really prefer if it was just the two of us next time. I don't know what to think so I show it to my wife, she doesn't know what to think either. So I just end up texting back "maybe you outta come back and teach her a little more" she reacts with a 😈. Seeing it all written out like this looks pretty bad, but it seems worse case scenario we can just admit we had a fun one night stand and call it at that.
