Great points. It's always difficult to duplicate the fantasy. You have it right, but it sure is fun trying! The first time my wife had sex with her coworker in our bed, it didn't go at all like either of us had envisioned and it turned out being a long-term relationship. It was way better than we ever expected.
Nope I would never do that, Once women know her the real you is, they will lose respect and besides Fantasies are so much better to think about When you try them it never seem to live up to the expectations
start by telling her you dreamed about licking her after she pees. Or by letting your wife know you'd be turned on if she wet her pants.....you can take it from there......she will love it.
