Hi guys, OP here. The dealer was femalel, I doubt she was older than 25 and we managed to laugh it off. After me nearly dying from embarrassment she actually asked what the book was. And no, it wasn't 50 Shades of Grey. It was not just the description of the act that was so bad, it was the moans and groans that the narrator put along with it. It sounded like really bad porn - not that I know what that sounds like! Thing is I was shocked when it came up in the audiobook, which is why it was stopped at that part. Later on I listened to the rest of it and boy was I glad that I managed to stop it when I did. I am really thankful that I found out about this feature before I took my parents for a drive.
