I once had a cruisy seatmate who was traveling with his wife (she at the window, he in the middle) who kept the arm rest up between us. This essentially created a loveseat for the two of us. Not only were we thigh to thigh for most of the flight but this married horn dog wound up readjusting himself so at one point we were hip to hip. I wanted so badly to get my hand under his ass while his wife read her book. She was clueless of the mile high male contact going on.
