I'd love to try it, but definitely not with a friend from outside the hobby. The other guy would have to be someone, that you'd meet thru the Hobby (at something along the lines of a meet & greet). No problem for me in "crossing swords"!
One favorite provider did comment regarding FMF, as "sensory overload" for the guy. "That", I told her, "would be one problem I would gladly experience". She laughed and returned her attention to my balls & cock, and planted her lovely ass back onto my waiting tongue!
