Don’t have an actual experience to share but I do have a story about this subject matter. As I have mentioned in other posts, there was a slightly younger woman I dated about 10 years ago who was fairly kinky and had some wild experiences in her past. In our many talks about what each of us wanted to do and experience sexually, she said she would gladly do a black guy while I watched, BUT there was one stipulation. I would have to remain seated and not play with myself or do anything until they were done and he was gone. She said she did not want me to get off and have any change of mind about what was happening. Now, whether she had a bad experience with that in the past before we met OR if she had read anything about others experiences gone wrong or whatever I don’t know. She never said and I never asked. However, either way, I think she was spot on with advice for someone’s first time to experience this. Best to be alone with the wife or GF when you cum just in case feeling go sour all of a sudden. Too bad we didn’t stay together long enough to get that far in our relationship. She seemed like a gal who knew how a lot of things should go when it came to kinks like this.
