My wife Stacy does this more than I wish she would. Though when she does wear underwear it's usually a thong, so either way she tends to show off more than I wish she would.

At first I loved the idea of a 3 some. A friend of mine and my wife did it a few years back. It didn't turn out well for me. My friend ( now ex friend ) has a really big cock, and he is more assertive that me. After the first time the three of us did it, my wife's pussy basically belonged to him for about 6 months. He made her cum from intercourse and I never have. Stacy has hardly allowed me to touch her pussy since then...and that was over two years ago. She allows me to touch her with my hands or mouth...but her pussy is basically off limits to my cock now. For guys my advice would be to not have a 3some with a superior cock alpha male type of Man.
