Hotel sex would be so hot with you.  Love to meet you in the lobby bar, have a drink and chat you up.  You could give me a signal that you were interested and we could sneak off to your room.  As we started to have sex, I would get the sense that we were being watched and sure enough your hubby would be in the closet watching us.  Once out of the closet he would have fun taking pictures and giving direction, even maybe showing you how he would like the scene to go (especially when it came to sucking cock).

{Knock, Knock!}....Hello, Ma'am -- your complimentary 'Room Service' is here now....

all the time you have to spare
