A woman's snatch, pussy, vajayjay when filled by the cum of multiple male partners, one after the other, in an orgy.
Gary let all his buddies bang the shit out of his girlfriend Mindy. They turned her pussy into a cumatorium before the night was over. She hobbled around sore for a week but loved every minute of it.
