I decided to put worrying about that.

Susan arrived a few minutes ahead of Trevor and Simon.
I had him he had brought a friend without telling I hope he did not mind if I did the same thing.
He shrugged and said "Fine." and left it at that.
We all went out to dinner and a bit of a drive.
Some how Trevor and Susan ended up in the front and me and Simon ended up on the back seat.
Simon started kissing me and his hands were everywhere on my tits between my legs.
At one point he took his belt off and knelt on the floor of the car. He then lifted my skirt and started licking me out.
Susan looked over the back and said "Maybe we should swap places I could do with some of that?"
I said "You called shotgun besides I like it back here."
Susan laught ( she has a realy nice laugh this was not it) and said "I wasn't talking to you. How about it Simon want to swap?"
