My Most Desired Fantasy

My wife is decently hot. She has an amazing ass mostly. I love it. Her sex drive is also fairly good, nothing compared to mine, but we get along. The problem is, she is not into anything freaky at all.

She will do certain things for me, like pissing on my face, a few public blow jobs, and she lets me film her or take pictures. Thats great, but there is one thing I dream of doing and I know if I ever brought it up, we'd be finished.

She would first off, know that I'm interested in men, slightly. That would be enough for her to end it right there.

My dream is for her to be on top of me, 69 position while getting fucked doggy style by another man. I want to suck her pussy, and occassionally suck on his cock. I want him to cum in her pussy, but just inside the edge, so it will flow down into my awaiting mouth.

I have never had cum from another man, although I eat a lot of mine. I just know I would love it. I can almost cum hands free just closing my eyes and imagining it.

I have found a few videos here and there, its not common though. I'm not even sure what to search for. Any help with that would be great btw. Has anyone tried that? Thoughts?
