Thanks everyone for your tips so far. I decided that I should just try the start out slowly route. My wife and I attended the PGA this morning at Baltusrol and she had on a fairly (but not too) short skirt. I told her a couple times that she looked really sexy, which she seemed to appreciate. I also told her a few times that guys were looking at her and checking her out. She seemed to like that. Anyway a start of sorts.
Kaktuscpl: Thanks for your reply-I want my wife to fuck strangers not people we know. And I doubt that even if I ever got her into this she is going to let another man cum in her (nor would it be safe). But if she ever did, I would certainly clean her up if she asked me too.. The main thing is I want to see her take a bigger cock than mine. I am 7" and fairly thick but a thick 8 or 9 incher would be awesome to watch her take.
