OK, I'm having a brain cramp and can't recall a story that I have somewhere on my PC, either a published book in Calibre or something from Literotica et. al.
It involves a husband and wife. There's a scene, early on, maybe chapter 2, where they are in Vegas and she picks up a guy and has her husband watch them get busy. She gives him her card afterwards and asks him to look them up if he's ever in their part of California. He does, and there are multiple group sex sessions with him and others.
The guy's name might be Jake, but that could be my brain misfiring.
I've tries to do searches for various bits of text that would match what I can recall, but have had no luck.
Does anyone know what this story could be?
