Mmmmmm if I was hubby and you wanted to do another girl and then a three some. Mmmm I would be so hard when you told me I would talk dirty suggesting girls for you to do. Even if it was your own sister or hot friend. Mmm
Another example of repressed sexuality in the South that does nothing but keep people from being happy. Most anti-gay men typically still find lesbianism hot and, if not, he's moat likely concerned about the competition. "What if the woman is a better lover and my wife leaves me?" In many cases the guy probably knows he has something to worry about cuz he's not doing his "job" well enough.
I agree with #2. Plus there's the hypocritical angle. Probably jerking off to MFF porn and fantasies of you and another hot female. Find you a nice married couple with a bi wife and well hung man with an open bedroom mind.
