3 somes

(Before I start I'd like to preface that my husband and I are in a great place in our marriage. We are not doing this to "save" our marriage or anything like that lol."

If anyone here has ever had a 3 some can you give me some pointers? My husband and I are having our first one this weekend. Mfm, it is a fantasy we both share.

We've invited our guest to dinner before hand to hopefully break the ice. But once we get back to our room I have no idea how to start.

He is someone we met online, been vetted, confirmed its him, std check, the whole 9. But he's still a stranger and I know it will be slightly awkward in the beginning.No one wanting to make the first move, or make it too soon.

So tips??
