So, my first wife and I did allot of freaky things especially with black men. She was a Mexican woman and was always wet and ready. To me there was always a moment that I could not stop myself from cumming, when I saw it.
When her lovers would cum inside her, she would look at me and I could tell they were cumming because she would always make that same face. She would mouth the words "he's cumming in me". I would instantaneously bust my nut.
Is there a moment that makes it impossible for you not to nut when you watch her with black cock?
