I have heard women discuss the "tall handsome stranger who steals into their boudior at night" sort of Romance Novel thing. I don't really understand that but I've heard it before. Fabio in the drapes sort of thing.
I think some fantasies are best left imagined but obviously a lot of folks feel differently.
I find it amazing how many portly middle aged housewives solicit for gang bangs....and their husbands encourage it. The sordid side of the internet is full of that stuff.
Amazing....why would a man want to share his wife...and watch?
People are weird.
