I personally like the attention you get when the girl helps you with your clothes.
Taking them off the hook or finding them after they were tossed all over the room and turning them back to the right way from being inside out.
 That can also be a fun part of the session.
But what if she just wants you out fast and it has nothing to do with her wanting to give you that extra attention.
She is just turned off, for whatever reason and needs you gone!
And I don't mean the session was good and she let you stay over your time and now there's another client due for their session.
I don't think it's happened to me, unless the girl was a good actress and I couldn't tell I was being rushed out the door.
