BDSM Dating in Chicago

Imagine...
You meet a couple. They're fun, open, honest. Nothing seems to be off limits.
He's the dominant. But he's respectful, open, and receptive to his wife. He's a pleasure dom.
She's submissive, but can be strong when needed. She's a natural nurturer. She winces with you while stroking your face and telling you "it's gonna be all right."
And they're sitting across the table from you. M/F/T/Couple/NB, doesn't matter. It's an experience anyway.
What do you do?
