We were having a tease and deny session when I brought up having another mans cock in her pussy. Her response was not positive, and said that I am taking our kinky sex too far. As I'm sliding little willy in and out of her pussy, I said, "imagine if that was a big black cock sliding in and out of your pussy". She did not say anything, but starting responding like it really turned her on. What should I make of this? Should I follow up? It also turned me on so much that I had an accident, and a ruined orgasm.
