Wife and I have only recently begun to talk about fantasies. She has not specifically mentioned a BBC but she has indicated a fantasy with a tall dark stranger at an art gallery or such. They would slip into a restroom, lock the door and they would kiss deeply and explore their bodies with hands and mouth. When they could stand it no more, she would lean against the wall, spread her legs and let him take her fully. And since it was only a fantasy, she would take his seed deep in her cunt. She does have some great fantasies. Not sure I will ever get her to act on them but one can hope. Certainly I would love to watch her enjoy a big black man.
