Is there anything on here about getting a 3way?

I am currently dating and brought up the idea of a 3some. my gf said she would be cool to do it with another girl

So im asking for some advice...

Who do we choose: a stranger, or her best friend?

How to go about it: Do you arrange for both to come over or do you all go out then come home together?

Choreography: what positions do you do to pull it off AND how do you go about dividing 1 cock into 2 vaginas fairly

What to expect afterwards: ??

thankyou

Don't choose her best friend. Don't do it. Did I already say you shouldn't do it? Don't. It'll backfire.

Make it a private party, at your place for example. A bit of alcohol could be quite of a help. Dude believe me, that won't be a problem. And besides you DO NOT want your actions depending on the advice on a forum. If youre really getting a 3 some, thats great and I don't think you need advice on how to do them. Besides you have a mouth too.
Just be sure you dont neglect your gf and go all on the other chick; and let the two of them have a lot of physical contact. Your gf is your #1. Pure joy. Pure bliss.
Bliss can be a state of profound satisfaction, happiness and joy, a constant state of mind, undisturbed by gain or loss. (wiki)

But you may also get your portion of drama and relationship struggle. It all depends on how your bond with your gf is, and if she really (really) wants this, or that you more or less manipulated her into doing this... ( Cant really blame you )

Best piece of advice I can give, orgasm with your girlfriend otherwise theres gonna be major issues after.
