I keep thinking of my straight laced wife who is 45 in bed with our neighbor,he is the same age as us but he is quite muscular and have on occasions seen my wife watching him in the garden when he has his shirt off. In my fantasy I come home from work early and catch them in our bed,they are both naked and he is thrusting his cock up inside my wife I watch them and wank myself while he gives Carol the best fucking of her life.I doubt this will ever happen but I can live in hope.
