I don't know how you'll find the right third party, but you'll all have to negotiate boundaries and expectations before he comes home with you. Though telling him that you and your girlfriend have always had the fantasy of sharing a man between you may get the ball rolling for some guys, be prepared for some men to run the other way. Even among those who accept, their performance will vary widely. Don't let him get drunk either, or your time together will be wasted.

Once things start, respond honestly. Don't cover your insecurities with bravado or passive acquiescence. Without blabbering or being apologetic, just speak the truth: "Wow, this is a little overwhelming for me," or "I'd love to see the two of you kiss." You can also set limits as you go along. If you want him to keep his hands outside of your panties until you get acquainted a bit, speak up. He'll likely be nervous too and will appreciate the guidance. You can always ask for more when you feel comfortable.

Pay attention to your responses and feelings. They'll let you know what works for you and what doesn't. You absolutely should not have a crying fit, dump on anyone, sit and pout or in any way throw a tantrum. If you're having a true meltdown and just can't get a grip, apologize, get dressed and tell your friend you'll talk to her tomorrow before taking your leave.
