Old man dreaming.....

I am an old gramps (M70) that is in a sexless marriage...wife gave up being intimate many years ago. For several years now, my dreams keep creeping to joining a free use family, as a distant relative type scenario. My thoughts go to sitting with, enjoying nice conversations over a beverage,,,all the while being naked with everyone in the household! My perfect dream, is a single Mom with a daughter, that is coming of age..and naive about men in general...so much so that Mom wants to give her a hands on approach to what males are all about...mind and body! I know it pretty far fetched, but Mom wants to show daughter in a safe environment, all of what happens between a man and woman...with no pressure or stress. Dreams do sometimes come true, even when they are out of reach.....
