So I've been with my girl for almost 8 years now, we had our ups and downs and splat up several time when we were both too young I think (mostly me). Now it has been 4 years since we started again in a more mature and healthy relationship.

She always had a fantasy of doing a threesome with 2 guys, spit roast style. I was a bit reluctant at first but then I said ok but I get to do a threesome with an other girl too afterwards. We weren't sure it was a good idea because what if we realize that we prefer having sex with someone else bla bla bla.

Now I realize sex and love are very different and I love her. I want to be more open about sex and explore more, revive the crazy sex we had at our beginning that clearly faded away with the years (see my other post if you want to go deeper on the subject).

So I have this idea of surprising her on her birthday. We are currently traveling and it would be the perfect occasion.

How should I proceed ? Surprise or talk seriously with her ?

In porn the girl awaits blindfolded and the husband come back with a guy, she starts sucking his cock not nowing and then, surprise, super hot threesome. But I know real life is very different and I'd really like some advice and opinions.
