I remember when this happened with the ex and her friend and her husband on a vacation for all four of us. He was bigger than me soft when I was hard. Needless to say he came in my wife several times. It turned me on so much though how much my cock was laughed at.
Poor fella....not only does he have a 4" cock fully erect but he also premature came in about 10 seconds!!....Added this great premature video to my premature favorites collection.
