When two or more individuals meet, more commonly at a nudist beach and engage in mutual (giving and receiving) maturbation on the beach.
Today I went to the nudist beach and this guy next to me had a really nice boner, he was looking at me...I was looking at his boner and then one this led to antoher and we had a "mutual sandy handy".
