A Double Decker Cream Pie Is when you have two girls and you cream pie in one of them and then the cum from one pussy drips into the other girls pussy.
Literally a gift from the Gods. This sensational bliss tastes of birthday cake and looks like a unicorn. Undoubtedly the best ice cream flavor to ever grace our universe.
Hey Anthony, do you wanna try the best thing ever???? THEN TRY SOME BIRTHDAY CAKE ICE CREAM!!!!!!!!! (:
