My wife has a peculiar view of cuckolding

Hi all, here I come with another question. I hope someone here can help me understand what to do.

Recently, I opened myself to my wife and told her I would like to be her cuckold. At first she didn’t understand and thought I was suggesting opening the couple, and didn’t like the idea. I explained to her that I don’t want this, but I just enjoy the idea of her having sex with whoever she likes but I don’t feel the same urge. I want to remain faithful just to her.

(You all know who a cuckold is: someone that likes to assist to his wife having sex with other people, or at least, if he is not allowed to watch, he likes the idea of the wife having sex with other people.)

I didn’t even hope that she would be into it. To my surprise, she was kinda into it, and said that she could like this agreement between us. However, she is not going to let it happen soon as she doesn’t fully trust my ability to accept it IRL. So she told me that I have to prove her that I can do it, and than she could give it a try.

The cuckold lifestyle she has in mind is a little bit different from what I fantasised about, tho. She told me that what I told her sounds like a porn fantasy. Instead, if she is ever doing this, it would be simply her going out and having sex with another man. Without warning me. She would be telling me about it only after it has happened. And since she knows I enjoy some humiliation, maybe she could do something like ordering me to massage her feet, and thats it.

She is not going to tell me beforehand, as she doesn’t like the idea of me thinking about her while she’s at it. She is not going to share details or tell me anything about the sex she had: she thinks that, since she is free to do anything, she doesn’t have to report me.

I both enjoy the idea of this happening and am scared at the same time. In some points of view, this just sounds like betrayal, not cuckolding. What do you think? Should I accept it or opt out before it’s too late?
