It is hard to narrow the fantasy downs because there are SO many things! If I had to narrow it down, would be while we are on vacation in the Caribbean, my wife loosens up a bit and after having some yummy drinks on the beach, she finally gives in out of pity for me to go naked. Then slowly a local or couple of locals start to move closer. I tell her they are massage technicians and I have set up a massage. Slightly resistant and irritated she says fine. One thing leads to another and she is cumming all over their fingers and is in full BBC Lust, the men strip down and she fucks and suck like a porn start unlike any way we have ever had sex. Ending with her riding a BBC reverse cowgirl and commanding me to suck her clit while she buck, grinds, and cums on a BBC!
