Wife agrees to much more than I expected

My wife agreed to more than I expected. I was kinda shy to tell her what I wanted. We have always been sexually hot. I told her I wanted her to dominate me and she is not sure what I want but wants to do this. Not sure where to point her for direction. I love having my cock and balls hurt, she loves hurting them. She is a beautiful tall brunette and I told her one of my fantasies is to watch her have sex with another man. There are many scenarios to the MMF that I and she want to explore. We went to the adult shop and looked at toys and stumred upon the dildo section I told her to point out her ideal cock that she would want for the MMF and I was surprised to see that it was barely thicker than mine and no longer. I asked her no really what do you want? She said that would make her come more than a 8 or 9 inch cock could. The dildo was 7" and a little thicker than average. I showed her the 9 inch thick dildo telling her I would love to watch her get blown out by a thick huge cock so I could get sloppy seconds from her and her bf cock, I told her I wanted to feel how blown out she was after taking the large cock and feel how wet he made her leaving his cum balls deep in my wife. She said she would do whatever I wanted but would enjoy the 7 inch thicker than average cock more. I told her she can have all of them. She wants to have me watch as another man fucks her good and rough. After they are done while I watch she wants me to climb on her and take back what was taken from me. I really can not wait until I see her hand wrapped around a cock guiding it into her pussy that is supposed to be reserved for me. I want to hear how much she likes fucking them with me watching. I told her I wanted a creampie and she didn't bat an eye at it. I love my wife!
