Me and my girlfriend have been having threesome fantasies for a long time and were wondering if any of you out there have tried it and how it affected your relationship.
My girlfriend had always wanted to try fuck another guy and have another guy's cock inside her. The thought of her getting fucked by another man had always turned me on. I was wondering how far to go though, she personally doesn't mind doing everything imaginable with the other guy, but I'm not so sure, though the fantasy does turn me on.
We were planning to try double penetration and creampies, as well as oral, vaginal and anal sex, with me watching my girlfriend getting fucked and sucking the other guy's cock.
Also, how would we find a guy? We're both in our early 20s.

It boils down to one thing jealous If you or her feel a bit jealous then it's not going to work. You should start slow maybe with a blow-job I'm sure you have a friend that would love a blow-job

Threesome's are a regular theme for couples who like sex and are adventurous. I had the same thoughts when I got a bit older (Nearing 40) while I was in my 20's I was so busy fucking my wife that I did not have those thoughts then. I started by trying to get my wife into watching porn but it bored her. I then started to bring this mfm situation up in our own sex life. It took some time but finally when prodding her to imagine someone she fancied fucking her it worked (It took a year) she said if I really wanted it so much she would do it just for me. That was an offer I immediately worked on, her one condition was that she wanted nothing to do with picking a stud and that was perfect by me. Today's internet contact sites make things easy, I had to place an advert in a swinging lifestyle magazine. I placed the advert with a picture and her face blocked out, nude lying on the beach, she had a terrific figure and the replies came thick and fast over 200. I had stated I wanted a guy with a big dick and I then proceeded to select six guys who sported the big ones. I ignored really good looking guys - well I'm not stupid. Eventually I got this one guy who traveled to our area on business, was married, good because I thought he would be more likely to be std free. I met him at his hotel and brought him home blind folded as I didn't want him to know where we lived. After about 1/2 hour of small talk my wife said well are we going to get started, which surprised me. they went into another room to get to know each other but I could see through glass doors after a few minutes she brought him in leading him by his cock, he had a huge hard on and she was dragging him in by it with the words is this big enough for you. It was! we then got into playing with him in front of a roaring log fire on the floor. He turned out to be a great stud considerate of both our needs and he came three times that night and I did too it was easily the most erotic night of my life. We met up with him about 6 times over 18 months and then my wife said "that's it I don't want to do this any more" So our little MFM came to an end. I took many video's and photo's and now even these have been thrown out. He eventually moved oversea's. We did all sorts including DP I thought my wife was really enjoying our meets but she wanted no more. When I asked her what was her favorite part of MFM she said definitely the foreplay two tongues four hands and the attention we gave her. She was not impressed by his big cock and said if she were she would never have married me! My advise is try it if your relationship is strong, you only live once, and it is so erotic to watch your wife climax by the joint efforts of two blokes.
