I would trust
@ENAUD to do it, and even give him part of the money if I remained alive.
No point negotiating it now, though this seems the most hypothetical of hypothetical situations, and like, I probably WOULD do it, for a million bucks.
Same goes if some dude wanted an "Evening of passion" with me, I'm pretty sure the husband would be understanding.
That is ALSO extraordinarily UNLIKELY to occur, but I would TOTALY do it, and I bet the husband would TOTALLY understand and it wouldn't ruin our marriage.
Of course, I would not fall for the guy, because anyone who would do that.
Also NO

to MOUTH.
That is RIGHT out.
