Once, MFF. It was a less than ideal situation. My then girlfriend, now wife and I had a mutual friend. We had some good chemistry and tension between the three us for a long time and a threesome was something that felt like it's going to happen sooner or later.

So at one night they went out to hang out with some friends and after that they both showed up at our place at night, dressed up, slightly drunk and all giggly. We drank more and ended up in the bedroom.

We drank too much, our friend didn't remember anything, I only remember some parts and my wife remembers but she didn't enjoy it. Friend went out to vomit during the bedroom fun, hopefully because of all the drinks she had...

Thankfully, both ladies are no drama and pretty laid back around the subject, so we stayed good friends, if it comes up we joke around and laugh about it. Despite the less than perfect outcome, I saw serious potential here, our friend wanted to try again too but my wife lost interest, understandably so.

So yeah, it was a bummer after such a long buildup, but I have to admit sitting next to the bed at some point, seeing only their bottoms when they were on top of each other and genuinely not knowing which lady part belongs to my wife and which is to our friend (they have very similar body types, plus I was drunk as you already know) was pretty awesome.
