The act of the granny stain involves a well matured female wearing adult diapers. Before sexual activity takes plac, the gilf unleashes a slick wet shit in the diaper. The male then removes the diaper and places it on the grannies chest at which point he mounts the grandmother in the missionary position and proceeds to smear the poo all over grannies chest with his chest.
