Dreams of what's to cum

My wife dreams a lot. She seldom dreams sexual things but did have one about us swapping with a couple that she is friends with. She was pretty vivid as Bill had her on her back and she was disappointed and she looked over at Nancy and I and she saw Nancy getting the pounding of her life. I took that as a high compliment and have brought it up over and over. She usually acts put out when I mention it. I have made up some dreams and told her about them and she has acted put out but finds them very sexy as I can tell by her body reaction she loves it. I had a dream the other night a real one. It was dumb as I dreamed she was sucking a young skinny guy's cock and he said, "You bent the wrong valve." Don't understand it but I told her about it and she just smiled. I loved it and was shocked in a good way. I need suggestions for things I could dream as right now our sex is on fire in preparation for our Florida trip and it will sound natural now. Any suggestions?
