Hello! So, my understanding of what a unicorn is that it is someone who joins a couple for a one time threesome and that’s it.

Now, I am making this post because my friend has told me that he and his girlfriend want me to be their unicorn, as in threesome. I responded telling him we needed to discuss more and asked if both would be available to meet in person.

I already gathered that we should discuss: - wants/needs - expectations - being tested and clean - boundaries - concerns

What else should be brought up/discussed? I don’t want our friendship to be ruined and I also do not want to ruin their relationship!

Any thoughts and advice on the matter would be greatly appreciated!
