To simultaneously and unselfishly scratch in a relaxing manner, the inside of each others forearms. When one is scratching, the other simply extends fingers so as to scratch the partners arm as well. Everyone is a winner.
Lying on the sofa trying to stay awake while watching Disney films, one extends arm onto partners lap, Tandem Scratch takes place and therefore both are getting even attention!
