We're an older couple. I'm in my 60's and my wife is 10 years younger. I have had honest discussions with my about the excitement I would derive from her fucking another man in my presence. She is still very interested in sex and I cannot satisfy her completely or as often as I did before. To my surprise and delight, she did not reject my proposal out of hand but rather she asked for time to consider it. I have developed various scenarios for her to consider that would assure her anonymity. It excites me immensely to think that this could happen. I further suggested that she have a black lover. Again her response was somewhat encouraging. I am moving slowly so as not to frighten her off. Suggestions?
