When one takes his or her finger to his rectum to apply the appropriate "waxy" residue and thereby wipes said finger across another's upper lip. Fyi, The smell lasts for hours.
oh yes the greasy grundle gamble is one of my favourite pastimes, the thrill of a lifetime! Its when you push your erect cock against the womans grundle. It will either slip in the vagina or slip in the ass and which ever hole it goes into is the hole you have sex in.
In the pink or in the stink, i can't decide lets have a greasy grundle gamble! By the grundlefull!
