My wife, Tara, is always trying different things to "keep our marriage fresh" as she says. Her latest kick is having sex in public. Well, not exactly in public but places where we might be seen, usually in the backseat of our SUV which has tinted rear windows. She's a bit of an exhibitionist anyway and I like watching guys watch her so sex in public was probably bound to happen sooner or later. She is also one of the horniest women you're likely to find. I laugh when I see that ad for the erectile dysfuntion drug that warns about 4 hour erections. I swear she would use all...
