Hi guys, I ve been married for 10 years and for the past months I ve been having these really strong fantasies about some other guy fucking my wife from behind while she is sucking my dick. In reality...I think that I would never want something like that...but when I m having these thoughts I get terribly excited..while we are having sex or masturbating..Just wondering why is this happening...and maybe share fantasies with other people in a simmilar situation...
