37 [M4F] Online/Greece - I'd like to explore my cuck side

Hello,

Last night I had a conversation with my wife and she mentioned that she would fuck an other man if he pays her 1 million dollars.

I instantly got super hard and I can't stop thinking about it.

I was a bit ashamed about it but I am still getting hard while thinking it.

Since then I think I may be a cuck but I don't want to discuss it with my wife yet.

Could you help me explore it?
