Scenario Fantasy
I think my wife missed her calling.... as a porn star. She's always been okay with Swapping, Swinging, Hotwifing..., but the latest MFM we had with a guy I vetting on Adult Friend Finders, my wife went all out on the visuals. The stranger had a decent sized cock. She immediately said, "No condoms". Which let all 3 of us know, this would be a cremepie. She gave HIM instructions: "I'm going to spread my lips, cover as much as you can outside. When you're close to the end, go ahead and stick it in".
My wife knew he still had some squirts left and she let him finish up inside her.
