Mixed feelings here. First off, I'm not a cuck. We personally think it's silly, but to each there own. I'm not a tiny dick white guy. Wife says I'm above average. I just love watching my wife get ultimate pleasure, weather it be from a true BBC, or another talented bi woman. If she is alone with another bi girl, I will give them privacy if the other girl requests it. If you are a guy, and going to be with my wife, I want to be there. I love to see the look on her face when you reach farther than I can. It's hot to watch. Now if you are an ABC (average black cock), and not a BBC, I don't care to watch. It's a color, AND size thing to me.
On the other hand, we got hit on by another white couple on a swing site. She only plays, and he watches? Felt kind of mixed feeling about that.
(It doesn't matter, because like most, after a week of getting the wife all horned up texting back and forth, and sharing picts, she fell of the face of the earth like the rest.)
