Hmm... I don't know if I've been in that situation either, but Cora and Dan certainly have--in the first book of my Wedding Heat series, "One in the Hand."
6 sentences from Wedding Heat: One in the Hand:
Dan undid his seatbelt and then his leather belt. He shifted to the middle of the bench, unbuttoning, unzipping. He was crushing Cora's maps, but when he pulled out his cock the maps were the last things on her mind.
“Thought you might want to finish what you started.” Dan stretched his arms across the back of the front seat, first toying with Cora’s hair, then pressing her head down.
