My wife got excited and confessed that she had a big cock

My wife got excited and confessed to me that she had sex with a cock bigger and thicker than mine once and again, but it wasn't thick, just much longer than mine. The truth is I don't know why it turned me on so much, never happened before. This time I even imagined what it was like when she told me how this big cock entered her. The truth is I even imagined it while we were having sex and it got me really hot. And then she said that's because she loves thick and veiny cocks but never had a partner who shares the same fantasy, until now that she has confessed to me all her fantasies and tastes. She told me she loves thick cocks and never had the chance to have one of her taste. I proposed doing a threesome with another man but she doesn't want anything to do with it. The reason for this post is so you can tell me why imagining myself having sex with that big cock turns me on so much. One thing I didn't understand, though - she said she didn't suck it because it's embarrassing, but I don't get how she knows it was bigger than mine if all she did was let the guy put his hand on her and measure it with her fingers? The truth is I can't believe that. I know it's embarrassing, but why not enjoy having sex with a cock you like and suck it too? She also told me that when they had sex, she loved how he squeezed all her pussy and then did it again the second time, but the guy didn't want to keep going because he wanted to break her ass and she was very thick. The guy didn't care and tried to put it in anyway and it hurt her badly. People, I'd like you to comment and tell me why this turns me on so much and if my wife will accept doing a threesome with another man and having a big cock. and enlarge it all and see her enjoy haha sounds crazy never happened to me but that's my fantasy and hers too but she doesn't dare haha
