Area between anus and testicular "sack." This includes the crack and cusp of the butt cheek between the anus and balls.
My girlfriend really wanted to just kiss my balls and shaft, but I pointed in a circular motion from ass cheek, to ass hole, to other ass cheek to ball sack and said:"No, get the WHOLE buntsack."
