I would give almost anything to watch and video my wife doing this: Sharing cocks with me, shamelessly fucking and sucking stranger after stranger in a public place with a line of guys waiting to use her naked body like a cheap fuck toy, and orgasming on the cocks and mouths of men whose names she doesn't even know.
The ultimate would be if they all went bare. I can't help it. As dangerous as it would be, I want her to want these random guys' cocks and cum inside her so badly, and to be so excited by the possibility of getting impregnated by them, that she's willing to have me devouring her creampies between each cock be the only hint of birth control.
