The weatern world has indeed become corrupt but that doesn't mean that you have to become a freak. Don't be stupid. Marriage is between ONE MAN and ONE WOMAN. 

Go for it with a stranger or a pro. She wont get attached and do it behind your back. YOu pick the dude. If he has a bigger cock, oh well. Then your turn with two girls plus your wife. Let one do here and switch to you wile you do anal on the hot one. Make BOTH hotter than her. Take control bro!

I love the feedback and this site. I guess half of the comments will be don't do it. The other half will be go ahead and say get her fucked. It's an intense sexual fantasy. We are married twenty years. No infidelities. Be it mfm or fmf, it will only enhance our sex lives.

It's still fantasy. We have never done more than lite anal fingering. Hers is virgin. Not a big thing to us. Until one day when I got all her holes filled. She sucked my cock in a side 69 position as I fingered her pussy with my left hand. I pushef my thumb on her anus and she fucked back hard and came and swallowed my load. I told her we have to try two before three

She will love it and so will you 

If you're both okay with both mfm and fmf and think it will enhance your sex life, then go for it.  Just be aware ahead of time that more times than not, bringing in another person "makes it real." You will be confronted with your wife actually having sex with another man, and vice versa.  Some people realize too late that the fantasy was better than the reality, and that they can't handle the sudden emotions that come with seeing the person they love with someone else.  Sometimes one partner ends up fine with it while the other was not - this can create jealousy and tension. And worst case scenario, one or both partners feel such an attraction to a third party that it causes stress in the relationship that can lead to infidelity.  Threesomes are only for those who feel they have an unbreakable emotional bond and committment to each other, and safest to the relationship when bringing in complete strangers each time.  Like using a new and different tool.  Using the same one more than once can cause a bit of favoritism, which is not good.  And always remember to be safe.
